▼ Increased awareness by farmers, scientists and farm advisors of the potential to expand the role of perennial pastures in livestock grazing systems has lead to the development and evaluation of new perennial pasture systems for livestock production in the high rainfall zone of south west Victoria. Increased stock carrying capacity per hectare compared to current common practice has been reported. In this study, the question investigated is: ‘Does investing in these new perennial pasture systems makes economic and financial sense considering risk for livestock graziers?’. A representative farm case study approach has been used to investigate the economic and financial merit, and the risk profile, of investing in either of two perennial pasture systems compared to current common practice. The representative farm was based on current common practice in the high rainfall zone in south west Victoria, running predominantly sheep producing wool and prime lambs, with a smaller beef enterprise. A partial discounted cash flow budget with a whole farm perspective was constructed to analyse investing in the new pasture systems on a 100 hectare portion of the farm. Investment in the perennial pasture systems was analysed over 12 years. The analysis investigated the effect of both seasonal and price variability on the performance of the new perennial pasture systems over time at a variety of stocking rates. The impact of establishment failure was also examined. The output of the model included the economic measures of net present value and internal rate of return, and the discounted net cash flow enabled financial evaluation. Size and timing of peak debt, time taken to return to positive net cash flows and loan servicing ability were analysed. The risk profile of the alternative future options was established using mean-variance efficiency analysis. Results from the analysis for the 100 hectare portion of the farm showed that, in general, both perennial pasture investment options promised returns on the capital invested of around 20%, which was greater than the opportunity cost of capital. The extra annual net cash flows generate was sufficient to service a 12 year loan under the conditions tested. The good performance of the new perennial pasture systems compared to the existing ‘Base Case’ was largely because supplementary feed requirements per head were reduced during the Summer/Autumn feed gap in most years and increased production per effective hectare that allowed higher stocking levels. Establishment failure substantially reduced the potential returns from the perennial pasture investment options, with the greatest effect seen at lower stocking rates. Whilst an advantage of the perennial pasture investment options was their ability to increase stocking rates per hectare and hence increase annual net cash flows, the analysis showed that the…

▼ The equine production system in New Zealand is largely pasture-based and as a result broodmares, foals and young horses acquire a significant percentage of their nutrition primarily from pasture. The reliance on pasture as the main nutrient source in New Zealand is in distinct contrast to the more intensive equine production systems found in other countries such as in Europe and North America. However, there is increasing scientific evidence that raising horses primarily on pasture may provide the optimal environment for the development of a sound and durable athlete. In addition, the supply of a balanced nutritional ration for the broodmare is important as inadequate nutrition can lead to reduced fertility. The requirement to produce a live healthy foal every year is crucial to maintaining the production cycle as mares which fail to conceive within a 25-day window post-partum eventually have to forgo a mating season which is costly to the business which relies on the sale of a young horse each year. The compositional data gathered during this study showed that equine breeding farm pastures were rarely deficient in energy, protein or fibre. The low energy content of pasture in summer and in some cases autumn was caused by high dead matter content and reproductive stem content. The presence of reproductive stem content and dead matter in the sward is linked to poor pasture utilisation, but can also be present during prolonged periods of climatic pressure (lack of rainfall). Lower nutritional quality of pasture is likely to be the main limitation to animal performance, especially in regions where summer temperature is high, rainfall is low, forage availability is reduced and the stocking density is high. During the breeding season commercial equine breeding farms experience a period of high stocking density which can be detrimental pasture quality and availability. Consideration of the recommended nutritional requirements of horses were made on the basis that there was sufficient dry matter (DM) available for the bloodstock to consume. The pasture management study found that there is an opportunity within the equine production system for improved pasture utilisation and production to allow for the provision of adequate nutrition to valuable bloodstock.

▼ Monensin (Rumensin 90®, Elanco Animal Health; Greenfield, IN) is a direct-fed ionophore that alters ruminal fermentation and has been shown to increase energy efficiency by altering VFA production in the rumen, resulting in improved forage utilization. This suggests that monensin has the potential to alleviate the effects of a cool-season perennial pasture “summer slump”. Weeds compete with desired forages for natural resources and can have a negative impact on livestock and pasture production. Grazing management strategies are implemented to encourage desirable forage growth and discourage the growth of undesirable species; suggesting that the implementation of rotational grazing could alleviate competition with weeds. In experiment 1, 32 spring-calving, Angus-based cow-calf pairs were stratified into pastures based on body weight (BW) and blocked by age. The study was conducted using 2x2 factorial, for 3 years (2015-2017) with 56-d grazing seasons each year. All cows were limit-fed wheat mid-based pellets with (MON; 200 mg/cow/day) or without monensin (NOMON). Treatments included 1) continuous grazing without monensin supplementation (CONT NOMON); 2) continuous grazing with monensin supplementation (CONT MON); 3) rotational grazing without monensin supplementation (ROT NOMON); and 4) rotational grazing with monensin supplementation (ROT MON). Cows in ROT were rotated every 7-d and desired forage height was maintained by put-and-take stocking. Precipitation was highest in June and July for Years 1 and 3, and lowest in Year 2. Temperatures were highest in July and August of Year 2 and this in combination with low precipitation created the ideal conditions for a true “summer slump” in PA in 2016. There were no grazing x supplement interactions, nor were there main effects of monensin inclusion or grazing management for Years 1 and 3 (P = 0.80 and P = 0.77, respectively). In Year 2, all cows lost BW and body condition score (BCS) from d 0 to 56, but cows on ROT receiving MON lost the least (grazing x supp: BW (P = 0.02) and BCS (P ≤ 0.01)).There were no main effects or interactions for carrying capacity (CC) or stocking rate (SR) in Years 1 and 3. Cows on ROT grazed pastures and cows receiving MON had greater CC and SR for grazing treatment (P = 0.07) and supplement treatment (P < 0.01) compared to CONT pastures and NOMON supplementation. In experiment 2, 32 cow-calf pairs were grazed over 2 consecutive years either ROT or CONT to determine the effects of grazing management on weeds as well as weed-forage nitrogen uptake. The amount of weeds present in ROT tended to decrease (P = 0.13) while CONT weeds remained the same. Kentucky bluegrass increased (P = 0.06) in pastures that were CONT grazed. Orchardgrass tended to decrease in CONT and increase in ROT (P = 0.14). There was a year x nitrogen content interaction (P = 0.03) with weeds having a higher percent nitrogen (N) content across both years. Weeds also had a total N content that was higher (P ≤ 0.0001) than the desired forages. During times of ample forage… Advisors/Committee Members: Jessica Williamson, Thesis Advisor/Co-Advisor, Tara Felix, Committee Member, Marvin Hall, Thesis Advisor/Co-Advisor.

▼ Treading damage by cattle in wet winters is an important limitation for all-grass wintering systems in New Zealand. This study evaluated the impact of cattle treading in winter on pasture plants in both hill country and flat dairy pasture over three trials. On hill country pasture, one severe treading treatment in winter resulted in losses in herbage accumulation rate of 9 kg (or 25%) DM ha-1 day-1 on tracks and 6 kg (or 26%) DM ha-1 day-1 on slopes compared to relatively untrodden treatments over a 9 month (Aug 98 to April 99) period. In repeatedly trodden treatments at heavy stocking rates, the loss in herbage accumulation rate averaged 19 kg (or 54%) DM ha-1 day-1 in tracks but found no loss on slopes compared to lightly grazed treatments over the same period. Treading seriously reduced pasture cover and changed species that contributed cover. In flat dairy pastures, the loss of herbage accumulation rate was 29 kg (or 36%) DM ha-1 day-1 in highly damaged areas, and 5 kg (or 7%) DM ha-1 day-1 in low- to medium-damaged areas compared to untrodden areas during the 7 weeks regrowth after treading. This loss in herbage accumulation rate was associated with an initial 66% reduction in grass tiller density in high-damaged areas. Treading also reduced leaf area index. Post-treading pasture cover was only 43% in high-damaged areas compared to 80% in untrodden areas. Compared to other grass species, perennial ryegrass was least affected by treading. Losses in herbage mass and tiller density as a result of treading recovered, or tended to recover, by the end of the 7-week regrowth period. In a second experiment on dairy pasture, treading in winter, again, greatly reduced residual herbage mass and tiller population density. Losses in both residual herbage mass and tiller density recovered by the end of the 7-week regrowth period. Differences in pasture height before treading did not effect pasture growth but, relative to the tall canopy height, the short canopy height enhanced tillering of ryegrass during the recovery period. The effect of treading on the weight of ryegrass tillers was small. An important aspect of treading was its role in increasing tiller appearance rate of ryegrass and encouraging faster growth of these newly developed tillers. Ryegrass-dominant pastures recovering from treading damage are reliant on the emergence and growth of new tillers.

▼ The objetive [sic] of the work described in this thesis was to develop a mathematical model designed as a tool for research intended to improve the efficiency of finishing systems for 1-2 year old beef cattle under intensive grazing mangement [sic] on sown pastures in Argentina. The work involved a) three experiments in Argentina carried out to define the effects of herbage allowance and maize grain supplementation on herbage intake and animal performance, b) one experiment in Argentina following a preliminary study in New Zealand of seasonal variation in the composition and nutritive value of intensively managed beef pastures, and c) an exercise to develop a model of beef cattle production incorporating modules dealing with aspects of pasture production and utiisation [sic], herbage intake and animal performance. The results from the series of short-term grazing studies showed consistency in the comparison of the effects of increasing herbage allowance and supplementation on herbage intake and animal LWG (Chapter 4). A method combining the use of n-alkane and 13C method proved to be accurate for quantitative estimates of herbage and maize grain intake, and allowed estimates of a substantial variation in individual maize grain intake (between 31 to 41 % CV) when animals are supplemented in groups. The substitution rate (SR) measured in these studies varied little across experiments or level of grain at a herbage DM allowance of 2.5 % LW d-1 (0.36 and 0.38 kg herbage DM per kg grain DM for Chapters 3 and 4 respectively). Increasing level of herbage DM allowance increased quadratically the SR from 0.38 to 0.83 and 0.87 kg herbage DM per kg grain DM. The n-alkane method was effective in providing estimates of diet digestibility. Different methods for estimating diet composition, such as microhistological evaluation of faeces, differences in nutrient and component selection indexes and n-alkanes were used in the initial grazing trial (Chapter 2) but they were not considered to be reliable and they were too laborious for continued use under field conditions. The outcome of the studies on seasonal variation in herbage quality initially was useful in establishing a database of the range of values observed, and in demonstrating their relative robustness, at least under conditions of good pasture management. In these studies, herbage nutritive value did not seem to be a limiting factor for growing beef cattle, at least in terms of the minimum observed content of metabolisable energy (10.8 MJ ME kg DM) or crude protein (17.3 % DM). Additionally, significant relationships were established between morphological and maturity estimates and herbage nutritional variables in a pasture under grazing conditions. These relationships showed promise for future use in the prediction of herbage nutritive value, but require further work. The model developed ("BeefSim"), represents the main biological dynamic processes of the target system of this thesis, together with additional management decision and financial estimates. It was shown that…

▼ Chicory (Cichorium intybus L.) is a perennial herb which has long been used as a forage crop. However, only recently has this species been re-evaluated in terms of its agronomy and animal performance. The objectives of this research were to study the persistence and the seasonal patterns of herbage mass accumulation and morphological development of forage chicory under defoliation. A series of field and glasshouse experiments were conducted at the Pasture and Crop Research Unit (PCRU), the Deer Research Unit (DRU) and the Plant Growth Unit (PGU), Massey University, Palmerston North, New Zealand (latitude 40°23'S) from 1993 to 1996. 'Grasslands Puna' chicory was used in all experiments except for one of the glasshouse experiments (Chapters 6 and 7) where two contrasting cultivars, 'PG90' and 'Orchies', were also included. Under grazing, Puna chicory accumulated herbage masses of 8.5, 9.4 and 4.6 t dry matter (DM)/ha from November to April, with average plant densities of 66, 69 and 24 plants/m2 and plant sizes of 2.9, 2.7 and 6.7 shoots/plant, for 1,2 and 4 year old stands, respectively (Chapters 3, 4 and 5). It was concluded that the characteristics of a grazed chicory crop that had deteriorated to the point of not being able to accumulate half of its maximum herbage mass were 25 plants/m2, six or more shoots/plant, or less than 150 shoots/m2. Defoliation stimulated the development of secondary shoots, but suppressed the growth of the primary shoot. Axillary shoots, however, developed fully regardless of whether or not plants were defoliated. The main source of feed from chicory for livestock was primary leaves during spring, and secondary and axillary leaves during summer and autumn (Chapters 4, 6 and 7). Results from both field and glasshouse experiments suggested that Puna chicory was more sensitive to defoliation frequency than intensity. It was concluded that defoliation at 50-100 mm in height at 3 week intervals in spring, and at 100-150 mm at 5 week intervals in summer and autumn, maximised the leaf formation and minimised the stem development of chicory. Grazing decreased the plant density of chicory regardless of grazing intensity or frequency, with the significant decrease in late spring and early summer when primary shoots were controlled (Chapters 3 and 4). Autumn grazing, especially hard grazing, was detrimental to plant persistence (Chapters 4). It was concluded that less grazing pressure through the growing season cannot be used to improve persistence without compromising leaf growth rate, but that avoidance of grazing in late autumn will improve the persistence of chicory. In a comparison of three cultivars, Orchies was the most persistent cultivar but had the slowest growth rate, and PG90 was the least persistent but with the highest growth rate, whereas the performance of Puna was intermediate, due to their contrasting root sizes and different root carbohydrate reserves. It was suggested that to improve the persistence and enhance the leaf production of Puna by plant breeding the emphasis should be…

▼ The purpose of this study was to examine whether the performance of prelamb shorn sheep is influenced by pasture allowance in the immediate post-shearing period and whether the relationship between performance and pasture allowance differed according to whether the ewes were shorn by standard comb (SC) or cover comb (CC). The trial was replicated across two years to allow for climatic variations that occurred between seasons which could markedly affect results. Fifty four ewes were used in each year in a 3x3x2 factorial design with three shearing treatments (ST) (SC, CC, and unshorn), three sward surface height (SSH) (nominal 3, 5, and 7 cm) and two pregnancy-status treatments (single and twin). There was an interaction between ST and SSH which resulted in liveweight gains during the period from pregnancy day 115 (P115) to P135 of 275, 613 and 4518 g; 1557, 2314 and 3997 g; and 3623, 2894 and 3997 g for SC, CC and unshorn (control) ewes set-stocked on 3, 5, and 7 cm SSH, respectively. There were no effects of ST or SSH on lamb weaning weight, ewe wool growth rate or mean fibre diameter. There was no interaction between ST and SSH for lamb birth weight (LBW), but the LBW of lambs bom to SC ewes (4.9±0.1 kg) was significantly heavier (P<0.05) than those of lambs born to unshorn (control) ewes (4.3 ± 0.1 kg). Rectal temperatures of SC or CC ewes were significantly lower (P<0.05) than those of unshorn (control) ewes on day 2 following shearing (S2), and on S4, S8, and S20. Pasture allowance, however, did not affect rectal temperatures of shorn ewes. Blood concentrations of glucose, NEFA or 3-OHB were not influenced by ST or SSH throughout the days of measurement. There were no effects of ST or SSH on ewe organic matter intake (OMI), except on the 2nd day following shearing where the OMIs of ewes set-stocked on 3 cm (941±147 g) were significantly lower than those ewes grazing 5 cm (1628± 101 g) or 7 cm (1349±135 g) SSH pasture. The results suggested that hypothermia, as determined by rectal temperatures and induced by pre-lamb shearing, cannot be avoided by pasture management. Neither the use of a standard comb for pre-lamb shearing, nor a low pasture allowance (3 cm SSH) affected short- or longterm production parameters.

▼ Traditionally, the emphasis in dairying systems in New Zealand has been on maintaining pasture quality in late spring through increased grazing pressure and occasionally topping. Recent studies have reported an increase in summer and autumn herbage production by allowing some reproductive development during spring, followed by a period of hard grazing at the time of anthesis when seed heads are immature and still palatable (late control), through effects on tiller population and size. The objectives of this study were to (i) evaluate whether the benefits of late control can be measured within the management constraints of a self-contained spring calving dairy production system, (ii) investigate the conditions under which late control spring grazing management can be implemented, and (iii) investigate the options available for the use of additional feed over spring and summer assuming late control spring grazing management is effective. A dairying systems study at No 4 Dairy Unit, Massey University was set up in which two 20-paddock perennial ryegrass/white clover dominant farmlets of 45 hectares were each stocked with 120 spring calving Friesian cows in October 1993 and run for three lactations until May 1996. With the exception of spring grazing management and spring supplement feeding the farmlets were balanced. The first treatment, designated early control (EC), involved strict control of grazing throughout the spring and summer with average pasture cover targeted at approximately 2000 kg DM ha-1 and a post-grazing residual of approximately 1500 kg DM ha-1. Pastures in the second treatment (late control - LC) were allowed to develop some reproductive growth through October and November for removal in December. Average pasture cover target was 2700 kg DM ha-1, with a post-grazing residual of approximately 2000 kg DM ha-1 over spring. Average pasture cover was reduced to 2000 kg DM ha-1 in December by grazing to lower residuals while at the same time removing paddocks from grazing for immediate conservation. Bayesian smoothing provided an alternative to analysis of variance (ANOVA) for those variables where both treatments and/or all replicates were not measured at the same point in time, and for large data sets and produced mean values close to those that would be produced by conventional analysis methods without the need to group arbitrarily. The development of a dynamic rising plate meter calibration equation which accounts for seasonal differences in pasture density allowed clearer definition of herbage mass estimates from rising plate meter measurements. Mass per unit height values showed a distinct seasonal pattern reflecting changes in the sward. The bulk density of pasture in the summer was found to be twice that in the winter. Overall, there was no extended period of difference between early control and late control in either pasture production or animal production during the three years of the trial. However, large differences in animal performance would not be expected considering the marginal differences…

Na alimentação animal se destaca o uso das pastagens. No entanto, em sua grande maioria encontram-se em algum grau de degradação física ou biológica. O objetivo do trabalho foi continuar o estudo da recuperação de pastagem degradada, iniciado em 2011, com estratégias de manejo do solo para introdução de estilosantes cv. Campo Grande (Stylosanthes capitata e S. macrocephala) em pastagem de Urochloa decumbens, em Latossolo Vermelho Amarelo distrófico, textura média. O delineamento experimental foi em blocos ao acaso, em esquema de parcelas subdivididas e quatro repetições. As parcelas foram formadas por sete estratégias de manejo para recuperação da pastagem: controle capim-decumbens (CB); capim-decumbens + estilosantes com plantio direto (PD), capim-decumbens + estilosantes com dessecação parcial com 1,5 L ha-1 de ingrediente ativo glifosato (DP); capim-decumbens + estilosantes com dessecação total com 3,0 L ha-1 de ingrediente ativo glifosato (DT); capim-decumbens + estilosantes com escarificação do solo (E), capim-decumbens + estilosantes com gradagem aradora (G) e capim-decumbens + estilosantes com aração + gradagem (AG). Nas subparcelas foi avaliada a presença e ausência da adubação fosfatada. O experimento foi realizado na Agência Paulista de Tecnologia dos Agronegócios – APTA do Extremo Oeste, no município de Andradina/SP com coleta de dados de agosto de 2015 a julho de 2016. Após 4 anos da implantação do experimento, a aração + gradagem proporcionou menor resistência mecânica a penetração do solo, enquanto o maior diâmetro médio ponderado do agregado foi com a utilização do plantio direto + dessecação parcial. A adubação fosfatada contribuiu para maior concentração de fósforo na forragem e na produção de massa seca e menor teor de FDN no período das águas. Os teores de fósforo no solo aumentaram em relação aos valores encontrados na implantação do experimento. O sistema plantio direto sem dessecação apresentou os maiores teores de cálcio, magnésio, soma de bases, capacidade de troca catiônica e saturação por bases.

In animal feed, highlights the use of pastures. However, the vast majority are in some degree of physical or biological degradation. The objective was to continue the study of degraded pasture recovery, which started in 2011, with ways of introducing estilosantes cv. Campo Grande (Stylosanthes capitata and S. macrocephala) grazing Urochloa decumbens and associated with phosphorus fertilization in Oxisol dystrophic, medium texture. The experiment was conducted at the São Paulo Agency Agribusiness Technologies - APTA Far West, in Andradina / SP with data collection from August 2015 to July 2016. The experimental design was a randomized block with split plots and four replications. The plots were formed seven management strategies for pasture recovery: control pasture U. decumbens (CB); U. decumbens + estilosantes with partial desiccation with 1.5 L ha-1 glyphosate (DP); U. decumbens + estilosantes with complete desiccation with 3.0 L ha-1 glyphosate (DT); U. decumbens + estilosantes with tillage…

▼ In naturally occurring ecosystems, forests function as substantial carbon sinks, storing carbon in soil and in biomass that would otherwise exist in the atmosphere as carbon dioxide. The conversion of forested land to cattle pastures and their associated operational processes are noteworthy contributors to recent increases in global carbon emissions and subsequent climate change. However, appropriately managed cattle pastures have potential to be reservoirs for carbon. Rotational cattle pastures, where cattle are moved between enclosed sections of pasture, may improve soil carbon content compared to conventional practices. In rotational cattle pastures, a more even distribution of manure increases plant biomass, and increased cattle movement decreases soil compaction, thereby reducing erosion and loss of soil carbon. This study quantified differences in soil carbon and bulk density (soil compaction) within and between a high-frequency rotational pasture (HFR), a low-frequency rotational pasture (LFR), and a conventional non-rotational (NR) pasture. Soil samples were collected from top, middle, and bottom slope positions and were separated by soil depth (0-10, 10-20, and 20-30 cm). Bulk density was determined using dry soil weights, and soil carbon was estimated as soil organic matter (SOM) with the loss-on-ignition technique. SOM was found to be greatest in the HFR pasture (6.61 ± 0.27%), followed by the LFR (6.00 ± 0.37%), and the NR pasture (3.47 ± 0.24%; p < 0.001). Inversely, bulk density was lowest in the HFR pasture (0.79 ± 0.01 g/cm3), followed by the LFR pasture (0.86 ± 0.04 g/cm3), and the NR pasture (0.93 ± 0.02 g/cm3; p < 0.001). Slope position had no effect on bulk density and only influenced SOM in the HFR pasture, such that SOM was greater at the top slope position (7.51 ± 0.51%) compared to the middle (6.25 ± 0.41%) and bottom (6.06 ± 0.40%) positions. Generally, SOM was greatest and bulk density lowest at 0-10 cm and SOM decreased and bulk density increased with lower soil depths. This study suggests that rotational cattle pastures could be one pathway for mitigating climate change through greater carbon sequestration and soil carbon storage.

O perfilhamento possui papel central na recuperação da área foliar e na determinação de padrões de crescimento da planta forrageira responsáveis por sua longevidade e produtividade. Contudo, pouco se conhece acerca do perfilhamento em plantas forrageiras topicais, particularmente a Brachiaria brizantha cv. Marandu (capimmarandu), uma das espécies mais utilizadas em áreas de pastagens plantadas no país. O objetivo deste trabalho foi estudar os padrões de perfilhamento e as características de perfilhos individuais, visando compreender melhor a resposta dessa planta forrageira ao pastejo e favorecer o planejamento e idealização de práticas de manejo adequadas. O experimento foi realizado em Piracicaba, SP, de outubro de 2004 a janeiro de 2006. Os tratamentos corresponderam à combinação entre duas intensidades (altura póspastejo de 10 e 15 cm) e dois intervalos de pastejo (período de tempo necessário para se atingir 95 e 100% de interceptação luminosa pelo dossel durante a rebrotação - IL), e foram alocados às unidades experimentais (piquetes de 1200 m2) segundo um arranjo fatorial 2 x 2 e delineamento de blocos completos casualizados, com 4 repetições. As variáveis analisadas foram densidade populacional de perfilhos (DPP), taxas de aparecimento (TAP), mortalidade (TMP) e sobrevivência (TSP), índice de estabilidade das populações (IE), índice de área foliar (IAF), site filing (SF), área foliar específica (AFE), razão área foliar:volume (R), taxa de crescimento absoluto (TCA), taxa de crescimento relativo (TCR), taxa de assimilação líquida (TAL), razão de área foliar (RAF) e razão de peso foliar (RPF), para perfilhos basais e aéreos. De forma geral, pastos manejados com 95% de IL apresentaram maior DPP basais que aqueles com 100% de IL, especialmente no final de primavera e verão, assim como maiores TAP e TMP, tanto basais quanto aéreos. Para ambos os tratamentos de IL foi constatado um padrão sazonal semelhante de variação em sobrevivência de perfilhos ao longo do experimento, com maior sobrevivência durante o outono/inverno. Adicionalmente, pastos manejados com 95% de IL apresentaram maior SF e AFE no início de primavera que aqueles com 100% de IL, indicando que estariam aptos a reiniciar o ciclo produtivo mais cedo no início da nova estação de crescimento. Reduções em IAF de perfilhos basais estiveram associadas a aumento em AFE de perfilhos basais e em IAF de perfilhos aéreos em todas as épocas do ano. O tratamento 100/10 resultou nos maiores e o tratamento 95/15 nos menores valores de R em todas as épocas do ano, sugerindo plasticidade e adaptação da planta às estratégias de pastejo avaliadas. No início e final de primavera de 2004, o tratamento 95/15 foi o que resultou em maior TCA, resultado dos maiores valores de TAL, RAF e RPF. O início da primavera é uma época crítica para restabelecimento das taxas de crescimento e perfilhamento dos pastos. Pastos de capim-marandu devem ser pastejados quando o dossel intercepta 95% de IL (25 cm de altura) e rebaixados até uma altura pós-pastejo de 15 cm.

The work was performed on agricultural properties, located on the hydrographyc sub-basins of the Santa Cruz and Ãgua Limpa streams, belonging to the Rio Grande basin, Lavras, MG, with the objective of evaluating and correlating soil physical attributes with pasture bromatological and productive aspects. Through soil chemical analysis, it was found that Santa Cruz sub-basin presented, in an overall way, better fertility conditions in relation to Ãgua Limpa. However, the fertility limitation in both areas reflects negatively in the pasture quality. In all soil samples analyzed high organic matter content was observed. The animal harsh treatment on these pastures, considering the amount of animals observed in the area and the continuous system of pasture, did not provoke higher values of bulk density, mainly at 0-10cm depth, than the subsurface layer. The total volume of pores values varied, in average, from 44 to 55%, independently of pasture type and sampling depth. As a general tendency, there were no differences between micro-porosity values in the soil under different types of pastures, also as no difference was observed between sampling depths. Although the depth sampling effect was not significant, a tendency of higher values of macro-porosity was observed in the superficial layer in comparison to the sub-superficial layer. On the aggregate stability evaluation through the average geometric diameter (DMG), the same tendency of the other evaluated attributes was observed. It was observed that the highest correlations occurred between dry matter production per hectare values and DMG and aggregates above 2 mm values. The pasture characteristics that were evaluated showed the reflex of degraded pastures. Through canonical correlation it was verified that pasture bromatological characteristics showed some association in itâs sensibility related to soil physical attributes in which they were found.

O trabalho foi realizado em propriedades rurais localizadas nas sub-bacias hidrogrÃficas dos ribeirÃes Santa Cruz e Ãgua Limpa, as quais pertencem Ã bacia do Rio Grande, em Lavras, MG, com o objetivo de avaliar e correlacionar os atributos fÃsicos do solo com as caracterÃsticas das pastagens do ponto de vista produtivo e bromatolÃgico. Por meio da anÃlise quÃmica de solo, constatou-se que a sub-bacia Santa Cruz apresenta, de modo geral, melhor condiÃÃo de fertilidade em relaÃÃo Ã Ãgua Limpa. No entanto, a limitaÃÃo de fertilidade em ambas as Ãreas reflete negativamente na qualidade das pastagens. Em todas as amostras de solo analisadas observou-se um elevado teor de matÃria orgÃnica. O pisoteio de animais nestas pastagens, na lotaÃÃo observada e em sistema de pastejo contÃnuo, nÃo levou, principalmente na camada de 0-10 cm, Ã obtenÃÃo de maiores valores para densidade do solo (Ds) em relaÃÃo Ã subsuperfÃcie. Independentemente do tipo de pasto e profundidade, os valores de VTP variaram, em mÃdia, de 44% a 55%. Como tendÃncia geral, nÃo houve diferenÃas entre os valores de microporosidade nos solos sob os diferentes tipos…

Devido à grande importância da infecção gastrointestinal na criação de ruminantes, especialmente em ovinos, a utilização de medicamentos anti-helmínticos é amplamente empregada pelos criadores. Esta prática, entretanto, apresenta elevados custos e tem resultado no surgimento de vermes resistentes aos princípios ativos disponíveis no mercado. Em atenção a este problema, pesquisadores de todo o mundo têm estudado formas de reduzir o grau de infecção parasitária sem a utilização exclusiva de medicação. Para tanto, têm-se dado enfoque para técnicas de manejo do pasto que ajudem na redução da população parasitária ambiental, e, consequentemente, na redução da carga parasitária dos animais. Diversos aspectos ambientais podem influenciar e favorecer a infestação parasitária das pastagens. Alguns deles, como o tipo e altura da forrageira utilizada, taxa de lotação e rotação de piquetes, podem ser manejados de forma racional com objetivo de reduzir a exposição dos animais aos vermes.

Due to the great importance of gastrointestinal infection in the creation of ruminants, especially sheep, the use of anthelmintic drugs are widely used by farmers. This practice, however, has high costs and has resulted in the emergence of worms resistant to active ingredients available. In response to this problem, researchers around the world have been studying ways to reduce the degree of parasitic infection without the exclusive use of medication. For this, have given focus to pasture management techniques that help in decrease the environmental parasite population and consequently reducing the parasite load of animals. Several environmental aspects can influence and favor the parasitic infestation of pastures. Some, like the height and type of forage used, stocking rate and rotation of paddocks, can be managed in a rational way in order to reduce the exposure of animals to the worms.

▼ Poultry and dairy production are important aspects of the agricultural economy in the Southern Piedmont of Georgia. Manures associated with this production are typically surface-applied to pastures as an economic fertilizer for forages. However, nutrients such as phosphorus (P) applied in manures may contribute to agricultural nonpoint pollution through contamination of surface runoff. This has potential to accelerate eutrophication of surface waters, which can harm aquatic life and complicate the water treatment process. Given that surface-applied manures can contribute to P in runoff, a study was conducted to examine agricultural management strategies to reduce export of P from grasslands with applied manures. Following application of either broiler litter or dairy slurry at the plot-scale in the first objective of the study, core aeration was shown to have the greatest potential for reducing P losses in runoff compared to discontinuous slit aeration with tines, continuous-furrow disk aeration, and a control of no aeration. The second objective, conducted at the field-scale, determined that continuous-furrow knife aeration was effective in reducing runoff volume (22%) and export of total P (18%) and dissolved reactive P (41%) compared to a control on well-drained soils and less effective on fields with more poorly-drained soils or a relatively high seasonal water table. In the third objective, the use of on-farm, field-scale runoff data determined that the Georgia P Index was well-suited for estimating the risk of edge-of-field P losses from fields under pasture or hay management in the Southern Piedmont. Furthermore, nutrient source (broiler litter, dairy slurry, inorganic N, and no amendments), forage system (hay or pasture), and year were significant factors affecting edge-of-field P losses. Results from this study suggest that core and continuous-furrow knife aeration procedures may have a widespread impact in reducing the levels of P exported from pastures receiving broiler litter in the Southern Piedmont. Additionally, the impact of agricultural management practices on P export from pasture and hay systems can be effectively modeled by farmers using the Georgia P Index, especially for farms with a low or medium risk of P export.

▼ Private pasture lands managed with rotational grazing practices for beef cattle production are being utilized by Aleutian cackling geese (Branta hutchinsii leucopareia) during their annual migration through northern California. Continued growth in the population size of this species has led to increased reports of forage depredation in pastures used by geese. To quantify reports of forage losses, research was conducted to determine effects different grazing conditions have on pasture regrowth. Field work was completed during the Aleutian goose spring staging periods in late winter/early spring in 2008/2009 and 2009/2010 on three ranches each season. Responses in pasture regrowth were studied under three different grazing conditions utilizing multiple study pastures on each ranch: 1) no grazing; 2) grazing by cattle only; and 3) grazing by cattle and Aleutian geese. Results from analyses showed that different grazing conditions led to statistically significant differences in pasture regrowth. Across all ranches over both seasons, regrowth in pastures with no grazing was 62% higher than cattle only grazing, and 280% higher than cattle and Aleutian goose grazing. Regrowth with cattle only grazing was nearly 140% higher than cattle and Aleutian goose grazing. This study confirmed that grazing by Aleutian geese impacted pasture regrowth that would have been otherwise available for cattle grazing and production. An economic analysis using results from this study was also performed. The difference between mean regrowth with cattle only grazing and cattle and Aleutian goose grazing was approximately 572.0 lbs/acre. Using the 2010 cost of grass hay of 150.00/ ton, the estimated cost of lost forage was 42.90 per acre. With the continued growth in the population of Aleutian geese, it is likely that forage losses from geese grazing on private pasture lands will also increase. Options to help offset losses to production should be investigated. Advisors/Committee Members: Fulgham, Kenneth.

▼ With the desire to increase milk production continuing the industry is developing ways to increase production without increasing costs. Two strategies to increase production are manipulating grazing residual to increase intake and pasture quality and through the addition of supplements into the system. There is ongoing debate over the most effective grazing residual to maximise milk production and maintain pasture quality. In this experiment the effect of post grazing pasture residual (PGPR) on long term pasture production, pasture quality and milk production has been investigated. Also the effect of supplementation on milk production and the interaction with PGPR has been examined. In a farmlet experiment, 32 mixed parity kiwicross cows were divided into four treatments low PGPR (grazed to 3.5 cm) without supplement (LR); high PGPR (grazed to 5cm) without supplement (HR); low PGPR with supplement (4kgDM/day)(LR+) and high PGPR with supplement (HR+). The experiment commenced in August 2012 and paddocks have been maintained under the same grazing management for two milking seasons with continual monitoring of milk production and pasture production and quality. In autumn 2014 additional measurements were taken to investigate the long term effect of PGPR on pasture characteristics. Increasing PGPR from 3.5 cm to 5cm reduced pasture production from 11,173 to 10,639 kgDM/ha for supplemented treatments and from 10,724 to 9,829 kgDM/ha (P<0.001) for un-supplemented treatments for the period 30/9/2013 to 12/5/2014. Botanical and nutritive composition changed throughout the season, but there was no significant difference between treatments. Milk production was greater for the supplemented treatments at 485 and 474 kgMS/cow/year for HR+ and LR+ respectively, and 425 and 418 kgMS/cow/year for HR and LR respectively. Milk solids per hectare was also increased with the addition of supplements at 2326, 2276, 1913 and 1880 kgMS/ha/year for the HR+, LR+, HR and LR treatments respectively (P<0.029). Milk composition was not affected by supplement although protein yield was greater under supplement treatments at 214, 207, 179 and 174 kg milk protein/cow/year for HR+, LR+, HR and LR treatments respectively (P<0.001).

▼ A Integração Lavoura-Pecuária (ILP) refere-se a uma associação entre duas atividades em épocas distintas do ano na mesma área, em que se envolvem os cultivos agrícolas e a criação animal. O presente trabalho teve por objetivos: (a) Avaliar a produção de matéria seca e fitomassa remanescente da pastagem consorciada de inverno (aveia preta, azevém e ervilhaca) sob diferentes alturas de massas de forragem póspastejo; (b) Comparar a produtividade da cultura do milho sob diferentes alturas de massas de forragem pós-pastejo e (c) Verificar as alterações nos atributos do solo que os bovinos possam causar no decorrer do ciclo vegetativo do milho. O experimento foi conduzido no município de Mata RS, em propriedade rural, durante os anos agrícolas 2009/2010 e 2010/2011, em um Argissolo Vermelho. O delineamento experimental foi o de blocos ao acaso, utilizando quatro alturas de massa de forragem pós-pastejo: pastejo convencional (PC), com área de 500 m2, em que não se tinha o controle de deslocamento dos animais e altura de massa de forragem durante o pastejo; altura de massa de forragem de 0,10 m (M-10); 0,20 m (M- 20), 0,30 m (M-30) e uma área não pastejada (SP). Para atender aos objetivos propostos, o trabalho foi dividido em três partes. A primeira parte foi realizada avaliando em duas épocas do ano agrícola, a densidade do solo, microporosidade, macroporosidade e porosidade total nas profundidades de 0,0-0,025; 0,025-0,05; 0,05-0,10 e 0,10-0,15 m, bem como a taxa de infiltração de água no solo, resistência mecânica do solo à penetração e teores de fósforo, potássio e matéria orgânica do solo. Quando manejada corretamente a presença dos animais em áreas de pastagem, não ocorrerá interferência negativa nos atributos físicos e químicos do solo. Após o ciclo de pastejo, não houve alterações nos atributos físicos do solo, o que não interferiu na taxa de infiltração de água no solo e resistência mecânica do solo à penetração. Os teores de matéria orgânica do solo mantiveram-se em progressão nos dois anos de avaliação em ambas as camadas avaliadas, o que não ocorreu com os teores de fósforo e potássio, havendo uma diminuição nos teores destes nutrientes em todas as camadas avaliadas. Na segunda parte do estudo, foram realizadas avaliações agronômicas e componentes de produção da cultura do milho. As alturas de massas de forragem pós-pastejo em 2009/2010 não afetaram o rendimento de matéria seca do milho, não se repetindo em 2010/2011, devido à baixa disponibilidade hídrica que ocorreu na região. Os componentes de rendimento da cultura do milho a MMG e o NGE foram influenciados negativamente pelas diferentes alturas de massa de forragem pós-pastejo, no ano de baixa disponibilidade hídrica. As menores alturas de massas de forragem pós-pastejo (M-10 e PC) não fornecem o aporte ideal de palhada para o SILP-PD para culturas subsequentes. Na terceira parte do trabalho, avaliaram-se atributos referentes à pastagem (altura da planta, massa de forragem disponível e massa final da forragem) e à dinâmica de produção de forragem em pastagem… Advisors/Committee Members: Flavio Luiz Foletto Eltz, Mastrângello Enívar Lanzanova, Thome Lovato, Fernando Luiz Ferreira de Quadros, Thomas Newton Martin.

▼ Overwintering of cows is a major cost in a cow-calf production system on the prairies. Winter feeding hay and straw directly on pasture is a potentially more efficient and economical system compared to conventional drylot feeding in a yard. The objectives of the research described in this thesis were to compare winter feeding cattle directly on pasture to traditional drylot over-wintering of cattle and the associated mechanized spreading of manure on pasture. This trial compared the effects of winter feeding systems on pasture nutrient distribution, nutrient recovery in soil and forage, pasture forage response, cattle performance, and economics. The experiment was conducted at Lanigan, SK, on an old russian wildrye grass pasture. Pasture nutrient levels and distribution were measured before and after winter feeding, as well as forage yield, and cattle weight and condition. Nutrient capture and cycling was assessed along with the economics of the different systems. In the pasture fed systems, cattle were fed by either bale processing or bale grazing methods over the winter of 2003-2004. Cattle concentration was 2080 cow-days ha-1, with the cattle in the field for 130 d. In the intensive system used for comparison, cattle were fed in a drylot and 67 tonnes ha-1 of raw manure or 22 tonnes ha-1 of compost was mechanically spread on the pasture in the fall of 2003.Soil inorganic nitrogen (N) levels (0-15 cm) measured in the spring where the cattle were winter fed on pasture were 3 to 4 times the unfertilized, unmanured control treatment, with a mean gain of 117 kg N ha-1. Soil inorganic N was not significantly elevated where manure or compost had been spread by machine. Soil extractable potassium (K) was doubled on the winter feeding sites, with a mean gain of 1209 kg K ha-1. Soil extractable K did not increase where manure or compost had been spread mechanically. Soil distribution patterns of both nutrients were highly uneven following pasture feeding, with levels of inorganic soil N ranging from 12 to 626 kg ha-1 and extractable soil K ranging from 718 to 6326 kg ha-1. Additional nutrients in surface residue from uneaten feed, bedding, and manure were also heavy and variable following pasture feeding. Greater retention of N and K from urine added directly to the soil in the field in the bale grazing and bale processing systems compared to the drylot system is believed to be responsible for high soil available N and K levels compared to manure hauled from the drylot into the field.Soil extractable phosphorus (P) levels (0-15 cm) were measured in the fall of 2005. The compost treatment had the largest increase at 2.6 times the control, an additional 46 kg ha-1. Mean soil P levels did not increase significantly where the cattle were wintered. Over 18 months and 3 harvests, forage dry matter yields where the cattle were fed on pasture were 3 to 5 times the control where the cattle were fed on the pasture, and 1.4 to 1.7 times the control where raw manure or compost was mechanically spread. Also, protein content of the… Advisors/Committee Members: Schoenau, Jeffrey J. (Jeff), Lardner, Bart, Nagy, Cecil, Knight, J. Diane, Iwaasa, Alan, Highmoor, Tim, Walley, Frances L..

▼ The economy of New Zealand is dependent largely on the export of products of the livestock industry. While there has lately been an upsurge in secondary industry, a basic lack of raw materials and cheap labour curtails New Zealand's ability to compete economically with other countries as a manufacturing nation. If New Zealand's position as one of the world's leading agricultural exporters is to be maintained or expanded then increased primary production must be achieved. Such an increase is also necessary to maintain or improve the high standard of living of a rapidly growing internal population. Three general factors are important when the problem of increasing livestock production is considered. 1. Nutrition 2. Breeding 3. Diseases and Pests The interest of the author lies with nutrition but the other two factors are clearly important if animal production is to be improved. Breeding is important particularly in relation to raising fertility and producing types of animals that will give optimum returns in particular environments. It must be remembered however, that genetic improvement by selection of livestock, though essential, is usually slow because of the low heritability of many productive characteristics. Pests and diseases can limit animal production, particularly at high stocking rates, so the prevention of epidemics and the eradication of persistent diseases such as footrot, brucellosis and tuberculosis must continue to be actively pursued. At a symposium entitled, "Problems of Increasing Sheep Production", held in February 1964 by the NewZealand Society of Animal Production, it was evident that the most effective short-term method of increasing animal production would be by increasing stocking rate. This infers increases in both animal numbers and the food to support them. Thus to increase the carrying capacity of the present farming area there must be an increase in the quality and quantity of pasture produced. This can be achieved in two ways: by techniques of pasture management and by breeding improved strains of pasture plants. It must also be remembered that considerable advances may be obtained with improved management of existing strains of pasture plants.

▼ Dairy producers across the country are evaluating the effectiveness of management intensive grazing (MIG) systems as a means of reducing the economic pressures of confinement feeding and manure handling. Systems using MIG have been promoted as an environmentally safer way of managing nutrient balance on Center. However, little research has been conducted to evaluate how these systems affect phosphorus (P) loss from the Center through runoff and forage removal. The goal of this study was to investigate the effects of forage type and manure density on P levels in runoff from release plots that simulated a MIG dairy system. Two forage treatments were planted on runoff release plots and applied with three manure density treatments and four replications of each combination for a total of 24 plots. Orchardgrass (Dactylis glomerata) and a broad-leafed forage treatment consisting of buckhorn plantain (Plantago lanceolata), red clover (Trifolium pratense), and alfalfa (Medicago sativa) were planted on the runoff release plots in early spring. Manure densities with no manure (control), a density simulating a low stocking density (low), and a density simulating high stocking density (high) were applied to plots during grazing simulations. Six rainfall simulations were conducted over the season simulating grazing conditions when forage was removed and re-growth conditions when forage had reached its target re-growth height before re-grazing occurred. Thirty minutes of runoff was collected from the runoff release plots to determine first flush phosphorus losses from the various treatments. Mass losses of total phosphorus (TP) for manure treatments in series 1 were significant due to plot installation disturbance. No significant effect for ortho-phosphorus (ortho-P), particulate phosphorus (PP) or TP concentration or mass losses were observed for other simulation series. Significantly higher mass losses were observed in series 1 for both forage treatments, again due to installation disturbance. Seasonal mass losses for TP were significantly lower for the orchardgrass treatment. Forage mass removal over the season increased as the stands established. Orchardgrass treatments appeared to control P losses earlier in the season, while broadleaf treatments observed a steady increase in ortho-P losses up to series 5. Both mass and concentration losses of TP were controlled earlier in the season by orchardgrass, while PP showed no significant mass or concentration loss effects.

▼ An increasing population of Aleutian cackling geese (Branta hutchinsii leucopareia) has sparked concerns over goose population and public land management in Northwestern California. Strategies are needed to reduce depredation of private agricultural grassland pastures by geese. A Field experiment was conducted to assess the amount of goose grazing in relation to several habitat treatments at Humboldt Bay National Wildlife Refuge. Pasture plots were either fertilized with slow release fertilizer or mechanically cultivated with berseem clover (Trifolium alexandrinum). During spring 2007 an index of grazing pressure was quantified using goose dropping counts. Vegetation quality and quantity were quantified within treatment areas. Fertilizing pastures increased crude protein content of plants and made them more attractive to geese. Fertilized plots received 42% more grazing pressure compared to control plots. Crude protein of vegetation in fertilized plots was 16% higher compared to control plots. Crude above-ground biomass inside exclosures within fertilized plot was 88% higher than control plots. Fertilized plots also produced nearly twice as much standing crop biomass, indicating the potential to increase goose use days available at the refuge. Estimated cost to fertilize one hectare of land was U. S. $89.24. Goose grazing pressure on clover treatment plots did not differ significantly from the control. However, clover plots were potentially so heavily favored by geese during early growth stages that they were not able to become well established in the pastures. Estimated cost to over-seed one hectare of land with clover was U. S. $38.44. Public land managers can contribute to maximizing carrying capacity of grassland refuge areas by managing vegetation to have optimal levels of biomass and crude protein. With this strategy land managers may be able to re-distribute geese across the landscape and reduce goose depredation on private lands.
