▼ This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified by age and body condition, and randomly allotted to a randomized block design (four blocks) with the following treatments: 1) Control, no livestock grazing; 2) low stocking, 0.36 animal units (AU)/ha; 3) moderate stocking, 0.72 AU/ha; and 4) high stocking, 1.08 AU/ha for a 42 d grazing period spanning from late May to early July. Using ruminally-cannulated cows, diet composition and masticate samples were taken, in May and July, following 20 min grazing bouts and were analyzed for forage fiber and crude protein. Treatments had no influence on cattle weight change and body condition (P > 0.10). In regard to foraging efficiency, grams per minute and bites per minute were lower in the early collection than the late collection (21.51 g/min vs. 31.21 g/min; 16.71 bite/min vs. 26.71 bite/min) and higher in the control pasture than the grazed pastures (31.21 g/min vs. 12.44 g/min; 26.71 bite/min vs. 12.70 bite/min; P < 0.05). In addition, grams per bite decreased linearly with increased stocking density (P < 0.05). Forage fiber (ADF and NDF) was lower in May compared to July whereas CP was higher in May compared to July (P < 0.01). Stocking density did not influence diet quality (P > 0.20). Botanical compositions of diets were 91.98% grass and 7.95% forb species, with beef cattle showing strong relative preference for grass (RPI = 1.69) and weak relative preference for forbs (RPI = 0.18). Shifts in diet composition and preference were noted in regard to stocking density with Idaho Fescue, Prairie Junegrass, Hawkweed species and Hoary Balsamroot (P < 0.05). In summary, cattle stocking density had minimal effect on diet quality and cattle performance, but did influence foraging efficiency, botanical composition of the diet, and relative preferences of beef cattle grazing on a bunchgrass prairie.

vii, 66 leaves, bound ill. 29 cm

Feed costs comprise the majority of the total production costs born by livestock producers, particularly cattle. Because the relative costs of feed are so great, a dramatic economic impact can be realized by utilizing the cheapest feeds available in the most efficient manner possible. In order to make efficient use of a feed, however, it is necessary for the producer to be able to predict how an animal or group of animals will respond to a given feed or mixed ration. A common method fur predicting this response is the use of computer models. Computer models meant to predict animal performance have been around fur some time, particularly fur cattle. Currently, these models are an integral component of most operations, in both temperate and tropical regions. However, these models have not been validated fur beef production in many tropical regions. Poor production by cattle in tropical regions, even in developed countries, bas been well-documented (Minson and Mcleod, 1970; Stobbs, 1971). Tropical regions differ from temperate regions in that the forages present are often lower in protein and higher in fiber, due to the higher solar intensity and faster growth rate. Also, nutrients in tropical grasses may not be as available to the animal as the same nutrients in temperate grasses, as the higher fiber concentration may bind more of the nutrients. The Cornell Net Carbohydrate and Protein System (CNCPS) is a mechanistic, deterministic, and static model based on the principles of rumen function, microbial growth, feed digestion and passage and animal physiology that was developed to predict requirements, feed utilization and nutrient excretion fur dairy and beef cattle. The system was first presented in a series of fuur papers (Fox et al, 1992; Russell et al, 1992; Sniffen et al, 1992; O'Connor et al, 1993) and has since been continually refined (Ainslie et al, 1993; Tylutki et al, 1994; Fox et al, 1995, 1999; Pitt et al, 1996; Tedeschi et al, 2000a, 2000b, 2001, 2002a, 2002b, 2002c, 2003). There have been several evaluations of the CNCPS model with animal performance data. Kolver et al (1998) used a total mixed ration (TMR) and grazing dairy cows to evaluate the performance of the CNCPS and found the CNCPS underpredicted energy allowable milk production by 2.5% in the animals fed TMR and by 6.8% in the animals fed pasture. Dairy replacement heifers have also been used to evaluate the predictions of the CNCPS. Van Amburgh and coworkers (1998) used both the CNCPS and the 1989 Dairy NRC with 273 Holstein replacement heifers. The CNCPS ME allowable ADO accounted for 86% of the actual ADO. The CNCPS has also been evaluated for tropical cattle production. Lanna et al (1996) measured energy and protein content of empty body weight gain of growing animals and milk production of dual purpose lactating cows. Using actual DMI of feeds that were characterized for carbohydrate content and protein fractions, as well as digestion rates, the CNCPS accounted for 72% of the variation in live weight gain…

Thesis M.S. Michigan State University. Animal Science 2018

Consumer interest in the source of their food, its environmental footprint, and the impact of diet on health has supported the growth of the grass-finished beef (GFB) industry. Studies have concluded that GFB has distinct nutritional differences from conventionally-finished beef. As the GFB industry continues to expand, it is vital to continue to explore the nutritional complexities and variation in the product. To achieve this aim, a survey of grass-finishing production systems throughout the U.S. was conducted, and the beef finished on participating farms was analyzed for its nutritional composition, including fatty acid (FA), mineral and fat-soluble vitamin content. Annual production capacity of farms ranged from 25 to 5,000 cattle, with a mean age of cattle at harvest of 26.8 ± 2.3 months. An array of finishing diets included grazing exclusively perennial pasture, the incorporation of annual forage crops, as well feeding a variety of harvested forages and supplementation of non-starch feed byproducts. The ratio of omega-6 (n-6) to omega-3 (n-3) FA in beef samples averaged by producer ranged from 1.8 to 28.3, with an overall sample set median of 4.1. Only n-3 FA varied between harvest season, with a greater amount found in beef harvested in the spring. Mineral content was highly variable by season and producer, due to the inherent variation of soil and forage mineral content. Mean α-tocopherol content was 610.6 μg/100 g beef, and mean β-carotene content was 32.2 μg/100 g. The amount of these antioxidants also varied between producers, but tended to be greater in beef finished solely on fresh forages. This survey indicates that commercially available GFB can vary in its nutritional composition due to the diverse practices used to grass-finish cattle.

▼ Linseed meal (LSM) was fed to ovariectomized ewes exposed to estradiol 17-? (E2) implants over time, and LSM was supplemented to beef cows during late gestation and early lactation to evaluate the estrogenic potential of the phytoestrogen secoisolariciresinol diglycoside (SDG) found in LSM. Forty-eight ovariectomized ewes were fed a diet containing 12.5% LSM for 0, 1, 7, or 14 d and implanted with estradiol-17? (E2) for 0, 6, or 24 h before tissue collection. Uterine cellular proliferation, vascularity, and the expression of the angiogenic factors and their receptors were recorded. There was an interaction of LSM and E2 on uterine mass (P = 0.05). At 24 h of E2 exposure, proliferation was reduced (P < 0.001) when ewes were fed for 14 d compared to being fed 0 or 1 days. There was a LSM x E2 interaction (P ? 0.03) on VEGF receptor-2 (KDR) and hasicfihrohlast growth factor receptor (FGFR2) decreasing by 24 h E2 exposure. Exposure of LSM and E2 may impact the estrogenic response of sensitive tissue. Two studies were conducted to examine the effects of supplementing beef cows with LSM during late gestation or early lactation on calf growth and development. In Experiment 1, multiparous cows received either LSM or a control (CON) supplement (approximately 10% diet dry matter) for the last 60 d of gestation. Offspring weights, ADG, heifer age at puberty, conception percentage and steer carcass characteristics were recorded. In Experiment 2, multiparous cows received LSM or CON supplements (approximately 10% diet dry matter) during the first 60 d of lactation, and only heifer calf development performance was observed and recorded. Heifer calf weight, average daily gain, and attainment of puberty were assessed. For both experiments, birth weight, weaning weight and ADG were not affected (P > 0.31) by LSM supplementation. While final body weights were heavier (P = 0.04) for steer calves in Experiment 1, there was no effect (P = 0.09) of supplementation on carcass characteristics. In Experiment 1 and 2, attainment of puberty in heifer calves was not influenced (P > 0.58) by supplement type. Linseed meal supplementation during late gestation or early lactation does not appear to have a negative impact on calf growth, onset of puberty in heifer calves, or steer carcass quality, implicating that it may make a good supplement choice in cattle.

▼ Ninety-two spring-born and 76 fall-born steer and heifer calves (Hereford and Angus x Hereford) averaging 188 and 255 kg, respectively, were utilized in a 2x2 factorial arrangement of treatments to study the effects of zeranol and monensin, alone and in combination, on growth rate, feed efficiency and carcass characteristics. After weaning, calves were stratified by weight for random allotment to four treatments: 1) control (no monensin, no zeranol); 2) zeranol alone; 3) monensin alone; and 4) zeranol-monensin combination. Zeranol (36 mg) was implanted subcutaneously in the ear every 90 days and monensin (200 mg) was fed daily. The diet for both growing periods consisted of hay free choice and a barley-biuret supplement. The diet of both finishing periods (steers only) consisted of a full feed of barley with limited hay intake and biuret for additional protein. Results for the spring-born calves indicated treatments 3 and 4 increased ADG (P<.05) during the winter (196 days) while feed efficiency for steers and heifers was improved by 8, 5; 24, 21; and 27, 11% on treatments 2, 3 and 4, respectively, as compared to 1. Average daily gain for the summer grazing period (98 days) was increased (P<.05) by treatments 2 and 4. During the finishing period (97 days), treatment 4 increased ADG (P<.05), while monensin improved feed efficiency by 12%. Overall ADG (391 days) for steers was increased 3, 7 and 16% on treatments 2, 3 and 4, respectively, as compared to 1. During the growing period (111 days), fall-born steers and heifers gained .68, .61; .86, .70; .82, .71; and .88, .86 kg, respectively, on treatments 1, 2, 3 and 4. All treatments increased gains (P<.05) over 1 with treatment 4 producing increased gains (P<.05) with the heifers. During the 153-day finishing period for treatments 1, 2, 3 and 4, gains were .85, .95, .92 and 1.01 kg, respectively, with treatments 2 and 3 different (P<.05) from 1 and treatment 4 different (P<.05) from 1 and 3. Again, monensin improved feed efficiency by 12%. Overall ADG (264 days) for steers was increased 13, 9 and 18% on treatments 2, 3 and 4, respectively, over 1. Carcass data for all steers indicated a one-third older maturity score (P<.05) for steers receiving zeranol. Zeranol-implanted steers also exhibited a tendency for a slight reduction in quality grade but improved (2.1 vs. 2.3) yield grade. Either zeranol or monensin produced an acceptable increase in gains, but the additive effect exhibited by their combination provided additional and more consistent gains during the growing and finishing periods.

▼ We conducted two experiments evaluating perennial ryegrass straw as a forage source for ruminants. Experiment 1 evaluated digestion and physiological variables in steers offered perennial ryegrass straw containing increasing levels of lolitrem B. Sixteen ruminally cannulated Angus X Hereford steers (231 ± 2 kg BW) were blocked by weight and assigned randomly to one of four treatments (TRT). Steers were provided perennial ryegrass straw at 120% of the previous 5-d average intake. Prior to straw feeding, soybean meal (SBM) was provided (0.1% BW; CP basis) to meet the estimated requirement for degradable intake protein. Low (L) and high (H) lolitrem B straws (<100 and 1550 ppb, respectively) were used to formulate TRT diets: LOW (100% L); LOW MIX (67% L:33% H); HIGH MIX (33% L:67% H); HIGH (100% H). Intake and digestibility of DM and OM, and ruminal pH, total VFA, and NH₃-N were not affected by increasing lolitrem B concentration (P>0.13). Ruminal indigestible ADF (IADF) fill increased linearly (P=0.01) and IADF passage rate (%/h) decreased linearly (P=0.04) as lolitrem B level increased. Experiment 2 evaluated performance and production of 72 Angus X Hereford cows (539 ± 5 kg BW) consuming perennial ryegrass straw containing increasing levels of lolitrem B during the last third of gestation. Cows were blocked by body condition score (BCS) and randomly assigned to one of three TRT. Cows were provided perennial ryegrass straw ad libitum and supplemented with SBM (0.1% BW; CP basis) to meet the estimated requirement for degradable intake protein. Mixtures of a L and H lolitrem B straw (467 and 2017 ppb, respectively) were used to formulate TRT diets: LOW (100% L); MIX (50% L:50% H); HIGH (100% H). Thirteen of 24 cows on the HIGH TRT exhibited signs of ryegrass staggers and were removed from the study. Dry matter intake was not affected (P>0.12) by increasing lolitrem B concentration; however, estimated DM digestibility decreased linearly (P<0.01) as lolitrem B concentration increased. Lolitrem B concentration did not influence pre- or post calving weight or BCS change (P>0.10). These data suggest that feeding perennial ryegrass straw containing up to 1550 ppb lolitrem B does not adversely affect nutrient digestion or physiological response variables in steers. However, providing straw with a lolitrem B concentration of approximately 2000 ppb resulted in 54% of cows exhibiting signs of ryegrass staggers. Blending of H and L straws appears to be a successful management practice.

▼ Three experiments were conducted to evaluate the influence of quality of supplemental alfalfa quality on beef cattle consuming low-quality meadow grass (MG) roughages. Fifteen steers (250 kg) were assigned randomly to one of three treatments: 1) meadow grass (5.2% CP), no supplement (MNS); 2) meadow grass plus high quality alfalfa hay (AHS) (18.8% CP); and 3) meadow grass plus low quality alfalfa hay (ALS) (15.2% CP). Supplements were fed at 0.45% BW and 0.55 % BW respectively. Total DM intake was greater (P<.01) for alfalfa supplemented steers. Likewise intake of digestible DM, DM digestibility and ruminal ammonia levels were greater for alfalfa supplemented steers (P<.01). In Exp. 2; 96 gestating Hereford x Simmental cows (537 kg; body condition 4.86) were assigned to the same treatments as in Exp. 1. For d-0 to d-42 cows grazed on 19.1 ha of stockpiled MG (4539 kg/ha; 6.8% CP) whereas d-43 to d-84, cows received MG hay (5.2% CP). Results for the 84-d study indicated that supplemented cows gained more BW (P<.01), body condition (P<.01) and had heavier (P<.01) calf birth weights than MNS cows. In the first 42-d period supplemented cows gained 16.2 kg more BW than MNS cows (P<.01). Likewise, supplemented cows increased .24 BC more (P<.01) than MNS cows. The same trend was observed from d-42 to d-84, though ALS cows lost more BC (P<.01) than the AHS cows. In Exp. 3; 90 gestating Angus x Hereford cows (475 kg; body condition 4.59) were assigned to one of three supplemental treatments: 1) 16.1% CP alfalfa; 2) 17.8% CP alfalfa; 3) 20.0% CP alfalfa. The level of supplementation was 0.63%, 0.55%, and 0.50% of BW, respectively. The basal diet was baled MG hay (5.6% CP). Weight gain and BC change for the 84-d study displayed a quadratic response (P<.10). In conclusion, alfalfa hay is an effective way of increasing low-quality roughage DM intake and digestibility. However, alfalfa hay quality did not appear to dramatically effect BW, BC, and (or) calf birth weights, when fed on a isonitrogenous basis.

▼ In this study subcutaneous, inter- and intramuscular fats from 42 Hereford steers were analyzed for their fatty acid composition using gas-liquid chromatography. The same tissues were analyzed from one pair each of identical twins of Angus and Shorthorn breeding. Muscle and liver lipids from these latter four animals were fractionated on silicic acid columns into glycerides and phospholipids prior to the fatty acid analysis. Feedlot performance and carcass characteristics data were also available on these animals. The data were analyzed statistically using analysis of variance techniques and simple correlations were calculated between all the variables studied with the exception of linolenic acid. Of the ten fatty acids quantitated, only the 17-carbon fatty acid and an 18-carbon branched chain acid were found to differ significantly between rations. Since both these acids are believed to be synthesized by certain rumen bacteria, these differences may reflect conditions in the rumen. No direct evidence is available. However, it is probable that this involves the availability of suitable precursors or rumen conditions favorable to these species of organisms. A highly significant relationship (r = .47) was found between average daily gain and linoleic acid. This relationship is probably also influenced by conditions in the rumen. A more rapid rate of passage or other factors which result in less extensive hydrogenation of polyunsaturated acids might also be conducive to more rapid growth. Essential fatty acids, such as linoleic, might be expected to reduce growth rates when they are deficient, however, no evidence of such a deficiency existed. Backfat thickness gave highly significant negative correlations with both myristic (r = .44) and palmitic acid (4 = .46) and was positively related to the 17- and 18-carbon fatty acids with the exception of stearic. Rib-eye area/CWT and estimated cutability, conversely, were positively and highly significantly correlated with the 14- and 16-carbon fatty acids and showed a negative relationship with the longer chained fatty acids. These relationships may indicate metabolic differences between the animals which deposit more lean tissue with less fat and those depositing greater amounts of fat. If, as these data indicate, meatier animals accumulate more of the 14- and 16-carbon fatty acids in the subcutaneous fat, a useful selection tool will be provided to the animal breeder. These 14- and 16-carbon fatty acids, in general showed a positive relationship between one another. When correlated with the 17- and 18-carbon fatty acids a negative relationship was observed. These negative relationships were particularly pronounced in the case of oleic and linoleic acids. It was suggested that the substitution of shorter chain saturated fatty acids for the longer chain unsaturates is the result of an attempt by the animal to maintain physical homeostasis of its depot fats. This assumption is based on the observation that the removal of carbon atoms… Advisors/Committee Members: Church, David C. (advisor).

▼ Studies were conducted at the Squaw Butte Experiment Station during two consecutive years to : (1) compare various internal indicators and chromic oxide to estimate forage intake and fecal production, (2) compare methods of producing slaughter weight steers using maximum quantities of forage and minimum quantities of grain. Actual fecal output of six 208 kg steers was correlated to chromic oxide (Cr₂0₃) estimates of fecal output for collection times of 0700, 1200, 1700 and composite with respective correlation coefficients of .63, .59, .80 and .79. The average recovery of Cr₂0₃ was 94.05⁺- 3.91%. Estimates of forage intake using lignin(L), crude fiber (CF), nitrogen (N) and indigestible dry matter were correlated to actual forage consumption with respective coefficients (r) of .92, .93, .96 and .89. No significant differences were found between collection times of 0700, 1200, 1700 and the composite sample for L, CF or N estimates of forage consumption. Estimates of forage consumption were most accurately predicted by the L and CF methods. Three trials conducted using a total of 129 Hereford or Hereford X Angus steers evaluated the performance of steers on irrigated pasture and crested wheatgrass range during the growing phase (trials 1 and 2). The steers were allotted to various finishing regimes from the growing study. These included finishing on irrigated pasture, on range and in the feedlot using two 40% roughage based rations for trial 1 and four 40% roughage based rations in trial 2. Trial 3 was conducted using fall born steers which were either immediately sent to the feedlot and fed two 38% straw based rations, put on irrigated pasture prior to going to the feedlot or grazed on irrigated pasture, wintered on a 100% forage diet of 2/3 alfalfa and 1/3 grass hay and then finished on crested wheatgrass range the following spring. Faster (P<.05) gains were made on crested wheatgrass range than on either alfalfa-fescue or clover-fescue irrigated pastures. Steers finished on irrigated pasture and range made greater daily gains than steers receiving the 40 roughage rations in the feedlot of trial 1. The feedlot steers gained faster in trial 2 with the range steers gaining the least (P<.05). In both trials the feedlot groups had greater (P<.05) 24 hour carcass weights due to a longer feeding period. Carcass grades were lowest for the alfalfa-fescue steers. Overall desirability of the beef was greatest for the feedlot steers. Daily gains were lowest (P<.05) for the fall born steers finished on crested wheatgrass as compared to steers finished on 40% roughage rations. Carcass weight, grade and marbling scores were not significantly different between treatments. Less than 86 kg of barley was used to produce slaughter weight steers from the crested wheatgrass range treatment. Advisors/Committee Members: Turner, Harley A. (advisor).

▼ Four groups of weanling Hereford heifers were placed on four different winter planes of nutrition for a period of two years according to the following pattern: Group I - Low plane of nutrition Group II - Medium-low plane of nutrition Group III - Medium-high plane of nutrition Group IV - High plane of nutrition During the summer seasons the heifers were kept on pasture providing the same feeding level for all animals. The one year old heifers were bred during the months of June and July. All animals were weighed weekly and feed consumption was recorded weekly. To illustrate the growth rate of the heifers, K-values were calculated for all animals by the method of least squares and their growth curves were constructed. At the end of the second winter period all parturition data were carefully recorded and the rate of growth of the calves studied. From the results obtained in this experiment the following conclusions can be drawn: (1) The first post-weaning winter period is very important in regard to the feeding level of young growing heifers. The medium-low plane of nutrition (Group II) showed the best results from the economic point of view. (2) Young heifers can be bred as yearlings if the previous winter-feeding level allows them to grow continuously and to reach at least 700 pounds body weight before the breeding period starts. (3) The gestation period did not result in a decreased growth rate of the bred heifers. (4) The physical difficulties of parturition in two year old heifers do not appear to be insurmountable if the winter plane of nutrition is adequate. (5) The lactation period means a heavy drain on the young female hence a high level of nutrition must be provided in terms of sufficient amount of pasture dry matter during the grazing season. (6) Average birth weight of calves was 62.9 pounds, being higher for bull calves than heifer calves. (7) Pasture dry matter requirements for beef cattle may be calculated from the following equation: DM = 0.17 w•⁷ (w is animal weight given in pounds)
