▼ Four studies were conducted to evaluate the efficacy of a delayed timed AI (TAI) protocol. The objective was to evaluate the use of Estrotect patch status to determine optimum TAI implementation. Experiment 1 was conducted with, 997 cows across 6 locations were administered a 7-d CO-Synch + controlled internal drug release (CIDR) estrous synchronization protocol. The experimental design was a 2 x 2 factorial; factors were patch status at 58 h post PGF2α injection (activated or inactivated) and time interval from PGF2α to TAI (58 or 76 h). Patch status was characterized at 58 h post PGF2α into 4 scores: 1 = 0% activated, 2 = 50% activated, 3 = 100% activated, and 4 = missing. Females with a patch status of 3 were considered to be activated and females with patch status of a 1 or 2 were considered to be not activated. Females with missing patches were removed. There was no treatment x location interaction for pregnancy rate (P = 0.96), so data were pooled across locations. There was a tendency (P = 0.07) for an interaction between the main effects for pregnancy rate. Pregnancy rate was greater (P < 0.01) in cows with activated patches at 58 h post PGF2α (67.0%) compared to those with inactivated patches (51.1%). There was no difference (P = 0.99) for pregnancy rate when comparing the 58 (59.9%) vs. 76 h PGF2α to TAI interval (58.7%). Pregnancy rates for cows with a patch status of 3 at 58 h post PGF2α were greater (P < 0.05) than cows with a patch status of 1 or 4 and tended (P = 0.09) to be greater than cows with a patch status of 2. Cows with a patch status of 1 tended (P = 0.06) to have increased pregnancy rates by delaying TAI to 76 h post PGF2α. Although, it was not different (P = 0.13), there was a 7.4 percentage point increase in pregnancy rates for cows with inactivated patches that received TAI at 76 vs. 58 h. Experiment 2 was conducted to evaluate delayed TAI on 1,682 heifers across 3 locations. The objective was to evaluate the use of Estrotect patch status at various recommended and delayed insemination times for a TAI protocol. Experiment 2a was implemented with 1,159 Bos taurus heifers synchronized using a 14 d melengestrol acetate (MGA) – PGF2α protocol. Estrotect patches were applied at the time of PGF2α injection and evaluated at the time of insemination. Heifers were subsequently assigned to 5 treatments: 1) recommended 72 h post PGF2α TAI with activated patches, 2) recommended 72 h post PGF2α TAI with inactivated patches, 3) 12 h delayed TAI with inactivated patches, 4)18 h delayed TAI with inactivated patches, and 5) heifers with missing patches. Experiment 2b was conducted with 449 Bos taurus heifers synchronized using a 14 d MGA – PGF2α protocol. Heifers were divided into 3 treatments: 1) recommended 72 h post PGF2α TAI with activated patches, 2) recommended 72 h post PGF2α TAI with inactivated patches, and 3) an 8 h delayed TAI with inactivated patches. Experiment 2c utilized 74 heifers synchronized with a 7-d CO-Synch plus CIDR protocol. All heifers had Estrotect patches… Advisors/Committee Members: Peel, Kraig (advisor), Ahola, Jason (advisor), Whittier, Jack (committee member), Hadrich, Joleen (committee member).

▼ Three studies were conducted to evaluate the efficacy of a timed AI (TAI) estrous synchronization protocol that used a 14-d controlled internal drug release (CIDR) insert and a GnRH injection on d 9 to force ovulation of potentially persistent follicles and induce a second wave of follicle growth. In the first study 710 yearling heifers across 4 locations were assigned to 1 of 3 treatments: 1) 14-d GnRH-9 heifers (n = 242) received CIDR (1.38 g progesterone) and 100 μg GnRH on d 0, 100 μg GnRH on d 9, and 50 mg PGF2α on d 14 concurrent with CIDR removal, 2) 14-d 6 h PG heifers (n = 233) were identical to 14-d GnRH-9 except that on d 14, 2 25 mg injections of PGF2α were given 6 h apart, and 3) 5-d CO-Synch + CIDR heifers (n = 235) received 100 μg GnRH and CIDR on d 9 and a single 25 mg PGF2α at CIDR removal. All 3 treatments received 100 μg GnRH with TAI at 72 ± 2 h after CIDR removal. The 14-d GnRH-9 TAI pregnancy rate (54.5%) did not differ (P = 0.57) from the 14-d 6h PG TAI pregnancy rate (53.6%). The TAI pregnancy rate of 14-d protocols combined was 54.1%, and was not different (P = 0.20) from the 5-d CO-Synch + CIDR TAI pregnancy rate of 46.4%. The following year 319 yearling heifers across 4 locations were assigned to 1 of 3 treatments: 1) 14-d GnRH-9 (n = 107; as described earlier), 2) 14-d PG (n = 107) was identical to 14-d GnRH-9 except instead of receiving GnRH on d 0 they received 25 mg of PGF2α and, 3) 5-d CO-Synch + CIDR (n = 104; as described earlier). All treatments received 100 μg GnRH at TAI 72 ± 2 h after CIDR removal. Heifers' ovaries (n = 120) were ultrasounded at 2 locations on d 0, 9, 14, and 17 of the estrous synchronization protocol to determine ovarian structures and response. The 14-d GnRH-9 TAI pregnancy rate (52.3%) was not different (P = 0.82) than 14-d PG (47.6%), nor was the TAI pregnancy rate of both 14-d treatments combined (50.0%) different (P = 0.66) from 5-d CO-Synch + CIDR (47.1%). Based on ultrasonography, the 14-d GnRH-9 treatment induced a second wave of follicular growth in 25.9% of heifers while 14-d PG heifers had larger (P = 0.01) follicle size on d 9 but did not reduce (P > 0.10) corpora lutea at TAI compared to 14-d GnRH-9 or 5-d CO-Synch + CIDR. That same year 453 heifers at another location were assigned to 1 of 3 treatments: 1) 14-d GnRH-9 (n = 150; as described earlier), 2) 14-d GnRH-7 (n = 150) received 100 μg GnRH and CIDR on d 0, 100 μg GnRH on d 7, 25 mg PGF2α on d 14 at CIDR removal, and 100 μg GnRH at TAI 63 ± 3 h after CIDR removal, and 3) 7-d CO-Synch + CIDR received 100 μg GnRH and CIDR on d 7, 25 mg PGF2α at CIDR removal, and 100 μg GnRH at TAI 63 ± 3 h after CIDR removal. Pregnancy rate to TAI of 14-d GnRH-9 (51.3%) was not different (P = 0.75) than 14-d GnRH-7 treatment (48.0%), nor was the TAI pregnancy rate of both 14-d treatments (49.6%) different (P = 0.83) from 7-d CO-Synch + CIDR (48.6%). These data indicate that the 14-d CIDR estrous synchronization protocol with d 9 GnRH produces comparable pregnancy rates to TAI compared to the industry utilized… Advisors/Committee Members: Peel, Kraig (advisor), Holt, Timothy (committee member), Ahola, Jason (committee member), Whittier, Jack (committee member).

▼ Two studies were conducted to evaluate the effects monensin sodium, plant extracts, and injectable trace minerals on heifer and bull fertility, and calf feedlot performance and morbidity. In the first study, Angus heifers (n = 107; 259.3 ± 21.0 d of age), blocked by weaning BW (262.7 ± 29.9 kg; d -19), were randomly assigned to treatments in a 2 x 2 factorial design, where all heifers received the same basal ration consisting of a 30% CP liquid supplement containing 200 mg/0.45 kg monensin sodium. Treatments were applied daily to the basal ration as topdressed supplements and were fed at a rate of 0.32 kg•hd-1•d-1. Treatments were as follows: 1) high level of monensin sodium (MON), where monensin sodium was topdressed at 200 mg•hd-1•d-1, 2) low level of monensin sodium plus the plant extracts cinnamaldehyde, capsicum oleoresin and eugenol (CCE), where plant extracts were topdressed at 11,000 mg•hd-1•d-1, 3) control (CON), low level of monensin sodium without topdressed supplements, or 4) high levels of monensin sodium with plant extracts (COMB), where monensin sodium was topdressed at 200 mg•hd-1•d-1 and plant extracts were topdressed at 11,000 mg•hd-1•d-1. In both studies, heifers were weighed and estrus detection patch status was recorded every 11 d. Age at puberty was determined by patch status and was recorded as the d the patch was first activated. A 14 d CIDR-PG-AI protocol was utilized to inseminate heifers, when heifers were 427.3 ± 21.0 d of age. In the 14 d CIDR-PG-AI, a controlled internal drug release device (CIDR) was inserted 33 d prior to AI and removed 14 d later. Prostaglandin was injected 16 d after CIDR removal, and heifers were inseminated 3 d later. Heifers were placed with bulls for natural service 21 d post AI. Pregnancy was determined 56 d post AI via ultrasound and 178 d post AI via rectal palpation. Calving records were used to validate ultrasound results. In the first study, there were no treatment main effects for initial or final BW (P > 0.05). There were no interactions between the main effects of monensin sodium fed at high concentrations and plant extracts for any feedlot or fertility performance variable (P > 0.05); however, there was a main effect of high levels of monensin sodium for heifer DMI from d 0 to 8 and d 8 to 15, where MON and COMB heifers had reduced DMI compared to CCE and CON heifers (P = 0.05). From d 11 to 22 and d 44 to 66, heifers that received plant extracts (CCE and COMB) had lower ADG than CON and MON heifers (P = 0.05). Feed efficiency tended (P = 0.08) to be improved in heifers fed high levels of monensin sodium (MON and COMB) compared to heifers fed low levels of monensin sodium (CCE and CON); however overall DMI, ADG, age at puberty and pregnancy rate were not affected by the main effects of high levels of monensin sodium or plant extracts (P > 0.05). In the second study, Angus bulls (n = 31, yr 1; n = 35, yr 2), heifers (n = 107) and steers (n = 105) were randomly assigned a treatment at weaning (278.6 ± 35.0 kg; 241.0 ± 19.6 d): 1) control (CON),… Advisors/Committee Members: Ahola, Jason (advisor), Peel, Kraig (advisor), Seidel, George (committee member), Engle, Terry (committee member).

▼ The overall objective of my thesis research was to improve procedures for vitrifying bovine blastocysts so as to enable direct embryo transfer to the uterus. Blastocysts were produced using standard in vitro procedures in Experiments 1, 2, and 3. Procedures were done at room temperature, 22 ± 2 °C. Unless otherwise mentioned, all media were made in SynGro®. In Experiment 1, base media contained either 1) normal concentrations of sodium (120 mM) and calcium (2 mM);(CON) or 2) 60 mM sodium + 60 mM choline chloride and 0.5 mM calcium (LOW). Blastocysts were exposed to 5 M ethylene glycol (V1) for 3 min and moved to 6.5 M ethylene glycol + 0.5 M galactose + 18% Ficoll (V2). Straws (0.25 mL) were loaded with a column of 120 μl 1 M galactose followed by an air bubble, then V2 containing embryos followed by an air bubble, and 60 μl 1 M galactose followed by sealing with a plastic plug. After 35 s, embryos were vitrified by either 1) standard cooling in liquid nitrogen cooled air (AIR) for 1 min or 2) cooling via contact of straw walls with columns drilled into an aluminum block immersed in liquid nitrogen (BLK) for 2 min and then directly plunged into liquid nitrogen. These combinations resulted in 4 treatments (AIR x CON; n = 61, AIR x LOW; n = 58, BLK x CON; n = 73, BLK x LOW; n = 54). BLK Embryos were warmed by holding straws in air for 10 s, placing them in a water bath at 37 °C for 20 s, mixing embryos with galactose diluent in the straw for 2 min and expelling. Embryos were recovered, rinsed through holding medium, and cultured in chemically defined medium (similar to synthetic oviduct fluid (SOF)) for 24 h before being evaluated for survival. Post warming survival did not differ (P > 0.10) between treatments (AIR x CON = 42.0%; AIR x LOW = 26.8%; BLK x CON = 21.8%, BLK x LOW = 24.5%). Despite lack of statistical significance, we recommend use of LOW base media because both sodium and calcium levels are reduced. Use of this media should therefore have less chance of sodium and calcium toxicity, and could deter apoptosis. The BLK vitrification method is both easier to use and more consistent. In Experiment 2, we sought to identify the most efficacious cryopreservation method for in vitro-produced bovine blastocysts that would enable direct embryo transfer from 0.25 mL straws used as containers for cryopreservation. Although not a method for direct transfer, Cryotops were chosen to serve as positive controls (CON), as they are the industry standard for vitrification of human embryos. Embryos were cryopreserved by vitrification with a Cryotop (CON; n = 118), using an aluminum block (BLK; n = 128), or by slow freezing (SLF; n = 131). Vitrification procedures were as described above for BLK with the exception that CON embryos were placed in < 1 μl V2 onto Cryotops, and after 35 s, vitrified by plunging directly into liquid nitrogen. Embryos cryopreserved via SLF were exposed to 1.36 M glycerol in modified Dulbecco's PBS + 0.4% BSA (PBS) for 10 min, loaded into 0.25 mL straws, and placed… Advisors/Committee Members: Seidel, George, Jr. E.

▼ In the first experiment, objectives were to determine the effectiveness of an extended controlled internal drug release (CIDR) insert estrus synchronization protocol to produce 2 follicular waves, induce cyclicity in anestrus cows, and evaluate the efficacy of a single 50 mg dose of prostaglandin F2α (PG) at CIDR removal. This experiment included 779 primiparous and multiparous lactating beef cows at 3 locations (n = 779) that were randomly assigned to 1 of 3 treatments. Cows in the 14-d 50 PG treatment received a CIDR (1.38 g progesterone) with 100 μg GnRH analogue im on d 0, 100 μg GnRH analogue im on d 9, and CIDR removal with 50 mg PG im on d 14. Cows in the 14-d 6 h PG treatment were assigned the same protocol as the 14-d 50 PG treatment except that 25 mg PG im was given on d 14, plus 25 mg PG im 6 ± 1 h later. Cows in the 5-day CO-Synch + CIDR (5-d CO-Synch) treatment, received a CIDR with 100 μg GnRH analogue im on d 9, CIDR removal with 25 mg PG im on d 14, and 25 mg PG im 6 ± 1 h after first PG injection. Cows in all treatments received 100 μg GnRH analogue im with TAI 72 ± 3 h after CIDR removal. Pregnancy status to TAI was determined by ultrasonography 37 to 40 d after TAI. Pregnancy rate to TAI was higher (P < 0.05) in 14-d 50 PG treatment than 14-d 6 h PG and 5-d CO-Synch treatments. In the following year, 2 experiments were conducted at 6 locations. Our objectives were to: 1) determine the efficacy of an extended CIDR protocol with 2 induced follicular waves, and 2) determine the ability of initiating the CIDR protocol with GnRH analogue (Factrel) or PG. In exp. one, 588 primiparous and multiparous lactating beef cows at 2 locations were randomly assigned to 1 of 3 treatments. Cows in the 14-d GnRH-9 treatment (n = 202) received the same treatment as the 14-d 50 PG as described earlier. Cows in the 14-d GnRH-7 treatment received a CIDR insert and 100 μg GnRH analogue im on d 0, 100 μg GnRH analogue im on d 7, and CIDR removal with 25 mg PG im on d 14. Cows in the 7-day CO-Synch + CIDR (7-d CO-Synch) treatment, received a CIDR insert and 100 μg GnRH analogue im on d 7, and CIDR removal concurrent with 25 mg PG im on d 14. Cows in all treatments received 100 μg GnRH analogue im with TAI at either 72 ± 3 h (14-d GnRH-9 treatment) or 63 ± 3 h (14-d GnRH-7 and 7-d CO-Synch treatments). Combined across all locations, pregnancy rates to TAI were not different (P > 0.05) between 14-d GnRH-9 (54.8%), 14-d GnRH-7 (54.4%), and 7-d CO-Synch (52.3%) treatments. In exp. two, 625 primiparous and multiparous lactating beef cows across 4 locations were randomly assigned to 1 of 3 treatments. Cows in the 14-d GnRH treatment (n = 205) received the same treatment as the 14-d 50 PG treatment described earlier. Cows in the 14-d PG treatment (n = 214) received the same treatment as 14-d GnRH cows except that 25 mg PG im was given on d 0 instead of GnRH analogue. Cows in the 5-day CO-Synch treatment (n = 206), received the same treatment as described previously. Cows in all treatments received 100 μg GnRH analogue im with… Advisors/Committee Members: Peel, Kraig (advisor), Whittier, Jack (advisor), Seidel, George (committee member), Ahola, Jason (committee member).

▼ In this dissertation we present applied, theoretical, and methodological advances in the statistical analysis of spatially-referenced and capture-recapture data. An important step in modeling spatially referenced data is choosing the spatial covariance function. Due to the development of a variety of covariance models, practitioners are faced with a myriad of choices for the covariance function. One of these choices is whether or not the covariance function is isotropic. Isotropy means that the covariance function depends only the distance between observations in space and not their relative direction. Part I of this dissertation focuses on nonparametric hypothesis tests of spatial isotropy. Statisticians have developed diagnostics, including graphical techniques and hypothesis tests, to assist in determining if an assumption of isotropy is adequate. Nonparametric tests of isotropy are one subset of these diagnostic methods, and while the theory for several nonparametric tests has been developed, the efficacy of these methods in practice is less understood. To begin part I of this dissertation, we develop a comprehensive review of nonparametric hypothesis tests of isotropy for spatially-referenced data. Our review provides informative graphics and insight about how nonparametric tests fit into the bigger picture of modeling spatial data and considerations for choosing a test of isotropy. An extensive simulation study offers comparisons of method performance and recommendations for test implementation. Our review also gives rise to a number of open research questions. In the second section of part I, we develop and demonstrate software that implements several of the tests. Because the tests were not available in software, we created the R package spTest, which implements a number of nonparametric tests of isotropy. The package is open source and available on the Comprehensive R Archive Network (CRAN). We provide a detailed demonstration of how to use spTest for testing isotropy on two spatially-referenced data sets. We offer insights into test limitations and how the tests can be used in conjunction with graphical techniques to evaluate isotropy properties. To conclude our work with spatially-referenced data in part I, we develop a new nonparametric test of spatial isotropy using the spectral representation of the spatial covariance function. Our new test overcomes some of the short-comings of other nonparametric tests. We develop theory that describes the distribution of our test statistic and explore the efficacy of our test via simulations and applications. We also note several difficulties in implementing the test, explore remedies to these difficulties, and propose several areas of future work. Finally, in part II of this dissertation, we shift our focus away from spatially-referenced data to capture-recapture data. Our capture-recapture work is motivated by methane concentration data collected by new mobile sensing technology. Because this technology is still in its infancy, there is a need to develop algorithms… Advisors/Committee Members: Hoeting, Jennifer A.

▼ Although leading veterinary organizations emphasize the importance of animal welfare knowledge, there exists a gap in current veterinary student animal welfare education and training. A survey instrument was created to assess third-year Doctor of Veterinary Medicine (DVM) student knowledge of key animal welfare topics, opinions regarding the inclusion of welfare education in the veterinary curriculum, and views on veterinarian responsibilities as advocates. In Spring 2018, Colorado State University added a required animal welfare course to the DVM curriculum. Pre- and post-course paper surveys were distributed to the third-year students enrolled in the animal welfare. One hundred thirty one completed pre-course surveys were collected and 125 completed post-course surveys were collected. Of the pre and post-course surveys collected, 61 were paired with identification codes and utilized for statistical comparison. Results indicated that the course led students to view the inclusion of an animal welfare course in the veterinary curriculum more favorably (p=0.009) and improved their confidence in conducting research on animal welfare topics (p<0.001). The course did not change students' sense of responsibility towards welfare advocacy. Associations were not found between attitudes towards these issues and demographic variables of home community, respondent gender, and track selection (p>0.06). Veterinarians were consistently ranked by students as the most influential member of a community in matters of animal welfare. Future research on the lack of veterinary student knowledge of animal welfare should be done on a national scale to facilitate strategic development of mandatory animal welfare courses in veterinary curricula. Future research should be designed to gain knowledge regarding DVM students' opinions and attitudes regarding effective methods of incorporating animal welfare education into their professional training. The objective of the second survey project was to evaluate the current pain management practices and opinions towards pain management in cattle of beef and dairy veterinarians and producers in the United States. Pain management strategies in livestock have evolved in the last few decades but a variety of obstacles continue to limit improvements in the use of pain mitigation by members of the cattle industries. One such obstacle is the lack of FDA-approved analgesic drugs for use in cattle in the United States which offers limited pain management options to cattle veterinarians and producers. An on-line survey was developed to investigate current use of pain mitigation by cattle veterinarians and producers. The survey was distributed electronically to multiple listservs in Summer 2018 (BEEF Magazine, American Association of Bovine Practitioners, National Milk Producers Federation Farmers Assuring Responsible Management evaluators, Dairy Moms and Dairy Girls Facebook groups; N=46,577). A total of 1,187 (2.5%) surveys were received; 41.9% of respondents identified as producers, 47.9% as veterinarians,… Advisors/Committee Members: Edwards-Callaway, Lily (advisor), Pinedo, Pablo (committee member), Ahola, Jason (committee member), Stuart, Amy K.

▼ For centuries, the natural ecology of rangelands has supported large herds of herbivores. The partnership between these herbivores and the land has usually been, and can continue to be a sustainable one. However, the debate over the use of public lands for cattle grazing continues to intensify. Scientific literature and corresponding recommendations regarding cattle management on rangelands are conflictual. This thesis proposes that the resolution is not to remove grazing from rangelands, but to effectively manage grazing for specific landscapes and ecosystem types. Grassland ecosystems are highly dynamic and maintained by continuous adaptation to biotic and abiotic events. Therefore, strategic grazing management that also incorporates dynamic adaptation to environmental conditions may produce successful outcomes with respect to cattle grazing and sustainable land management. The objective of this study was to compare selected indicators of rangeland health in ungrazed areas to adjacent areas where strategic grazing management had been implemented. It was hypothesized that compared to areas excluded from grazing, areas where strategic grazing was implemented would exhibit: increased nutrient cycling by integration of organic carbon and nitrogen into the soil, increased abundance of native graminoids and native forbs, and reduced abundance of noxious weeds. It was hypothesized that forage quality would follow a particular pattern because of grazing: a decrease in forage quality shortly following grazing, an increase in forage quality with a period of rest, and a decrease in forage quality with continued absence of grazing. Paired grazed and ungrazed areas were established in 6 pastures across a grassland valley on Colorado's Front Range, which had not been grazed for at least 10 years. In 2016, baseline data were collected from both grazed and ungrazed areas prior to grazing. Subsequent data were collected in 2017, following strategic grazing management and adequate rest. Linear mixed models were used to compare differences between grazed and ungrazed areas. Results indicated no significant differences in soil organic carbon (P = 0.97), total nitrogen (P = 0.64), relative abundance of native graminoids (P = 0.15) or relative abundance of forbs/subshrubs (P = 0.74) between grazed and ungrazed areas. In regards to forage quality, crude protein was lower (P = <0.01) and neutral detergent fiber was higher (P = 0.05) at the conclusion of the grazing period, but acid detergent fiber did not differ (P = 0.51) in grazed versus ungrazed areas. Additionally, areas that were grazed in the spring and received 2-3 months of rest demonstrated higher forage quality than areas that were grazed in the fall and received 9-10 months of rest as indicated by higher crude protein (P = 0.03), and a tendency for lower neutral detergent fiber (P = 0.06), but no difference in acid detergent fiber (P = 0.97). Chi-square tests for soil and vegetation variables detected no variation between pairs of grazed and ungrazed areas across the… Advisors/Committee Members: Rhoades, Ryan (advisor), Ahola, Jason (advisor), Brummer, Joe (committee member), Meiman, Paul (committee member), Turk, Philip (committee member).

▼ The objectives of this research were to evaluate the effects of: 1) castration, 2) castration method (band vs. surgical) and 3) use of analgesia on measures of behavior, feedlot performance, and physiological responses in cull bulls. In the first study, Angus, Hereford, and Angus crossbred bulls (n = 20; initial BW = 384 ± 59.3 kg; 336 ± 20.1 d old) were housed in feedlot pens equipped with the ability to measure individual daily feed intake. A balanced randomized block design using a 2 × 2 factorial arrangement of treatments was utilized. Factors included: 1) castration method (band vs. surgical), and 2) analgesia presence. A multimodal analgesia protocol (MMA) was used and consisted of subcutaneous ketamine-stun containing butorphanol (0.01 mg/kg), xylazine (0.02 mg/kg), ketamine (0.04 mg/kg), and a local 2% lidocaine hydrochloride anesthetic block of the spermatic cords (10 mL per cord) and scrotum (10 mL) on d 0. Flunixin meglumine (1.2 mg/kg) was also administered intravenously (iv) on d 0, 1, 2 and 3 to MMA cattle. Cattle were stratified to treatments based on breed, BW, age and a temperament score. Treatments included: 1) band castration without analgesia (BAND), 2) band castration with analgesia (BAND-MMA), 3) surgical castration without analgesia (SURG), and 4) surgical castration with analgesia (SURG-MMA). All castrations were performed on d 0. Chute exit velocity (EV) and time in chute (TIC) were collected on d -9, 0, 1, 2 and 13. Willingness-to-enter-chute (WTE) score, rectal temperature (TEMP), heart rate (HR), and respiration (RESP) were collected on d 0, 1, 2, 3 and 13. Cattle were weighed on d -9 and 13 while feeding behaviors were collected continuously for 57 d pre-castration and 28 d post-castration. There was a tendency (P < 0.09) for ADG to be greater in cattle receiving analgesia. Both SURG treatments exhibited greater TEMP on d 1 (P < 0.001) and 2 (P < 0.05) compared to both BAND treatments. Mean DMI post-castration was greater (P = 0.02) in MMA treatments compared with non-medicated treatments. Meal duration was greater (P < 0.05) in both BAND treatments than in surgical castrates in wk 1 post-castration. Results suggest that pain mitigation reduces the impact of castration on ADG and DMI. The second study was comprised of 2 experiments. In Exp. 1 Angus and Charolais-crossbred bull calves (n = 127; 309.8 ± 59.04 kg) and in Exp. 2 Hereford, Angus, and Hereford × Angus crossbred bulls (n = 30, 300.8 ± 4.96 kg), were stratified by BW and randomly assigned to 1 of 3 treatments: 1) band castration (BAND), 2) band castration with oral administration of meloxicam (BAND-MEL), and 3) sham castration (SHAM). The BAND and SHAM procedures were completed on d 0. The SHAM treatment consisted of all animal manipulations associated with band castration without band application. Meloxicam was administered on d -1, 0, and 1 (1.0 mg/kg, 0.5 mg/kg and 0.5 mg/kg, respectively) via an oral bolus. Body weight and a subjective chute score (CS) were collected on d -1, 0, 1, 7, 14, 21 and 28 (Exp. 1 only).

▼ Quality is an accumulation of attributes that satisfy customer preferences and expectations. Lamb quality is a moving target that means different things to the supply chain and sheep/lamb industry stakeholders. The objectives of this research were to determine the rank, definition, relative preference, and willingness to pay (WTP) for seven quality attributes and quantify product attributes of lamb at U.S. retail markets. Structured interviews of retail and foodservice respondents were conducted from May 2014 to March 2015 via face-to-face or telephone with lamb/protein purchaser representatives of retail (n = 60), foodservice (n = 45), and purveyor (n = 15) marketing sectors. Shares of preference (relative percentage of preference) in best/worst evaluation for all interviews indicated that eating satisfaction (38.9%) was the most important attribute. Shares of preference for all seven specified quality attributes were statistically different from each other (P < 0.05). Credence attributes of origin (17.2%) and sheep raising practices (13.6%) ranked second and third overall, respectively. Physical product characteristic traits of product appearance/composition (10.5%) and weight/size (8.5%) were ranked fourth and fifth in shares of preference, respectively. Nutrition/wholesomeness (7.1%) ranked sixth and product convenience/form (4.2%) ranked seventh in the overall ranking across all sectors of retailer, foodservice, and purveyor interview respondents. In WTP analyses, origin (25.8%) and sheep raising practices (20.0%) had the greatest likelihood of being a non-negotiable requirement for lamb purchasers. Eating satisfaction was the trait most likely to receive a premium (71.7%) from buyers, and product assurance of eating satisfaction generated the greatest average WTP premium (18.6%). This research indicated, across all sectors, eating satisfaction, defined as lamb flavor/taste, was the most important quality trait to those who purchase lamb. In-store evaluations of retail lamb labels showed that lamb shoulder and loin chops originating from the U.S. garnered the greatest price premiums compared to either New Zealand or Australian lamb (P < 0.05). Lamb was merchandised to American consumers at specialty type stores at an increased price per kg premium than either locally owned or national grocery chains (P < 0.05). Lamb shoulder prices at retail were merchandised with the greatest premium for product of U.S. origin from a specialty store packaged in modified atmosphere packaging and labeled with local (+ 5.42/kg) and natural (+ 5.40/kg) claims (P < 0.05). Lamb loin prices at retail were merchandised with the greatest premium for product of U.S. origin from a specialty store merchandised in a full service case or modified atmosphere packaged and labeled with a source verified and branded (+ 7.21/kg) label claim (P < 0.05). Shoulder and loin chop prices analyzed via hedonic modeling were not different for store location (East, Central, and West) nor USDA process verified Never-Ever 3 claim (P >… Advisors/Committee Members: Belk, Keith E.

▼ The National Dairy Farmers Assuring Responsible Management (FARM) Animal Care program provides guidelines for farms producing 98% of the U.S. milk supply. Producers who sell milk to co-ops or processors participating in FARM must follow animal care standards defined by the program's technical writing group. Objectives of this study were to assess producers' perceptions about knowledge, experience, value, and reasons for considering FARM important, and to determine if perceptions differ based on producer demographics. Quantitative and qualitative data were collected from a 30-question survey instrument. Quantitative questions aimed to address project objectives, and qualitative data were provided through one open-ended survey question that asked participants what they thought the main goal of the FARM program was. Additional feedback was offered by participants through providing text in comment boxes, writing on the back of the survey, or writing a separate letter and returning it with their survey. Quantitative data were analyzed using principal components analysis and qualitative were analyzed through thematic analysis. Themes for the qualitative data were constructed through a set of initial codes which were developed from patterns found in the data. The use of triangulation, debriefing, clarification of researcher positionality, and audit trails were used to enhance trustworthiness of the study. Dairy producers from collaborating dairy co-ops and processors were recruited via electronic and postal mail. A total of 487 respondents from 40 states completed the survey. Of the survey participants, n = 414 (85%) answered the open-ended question, and n = 190 (39%) provided additional qualitative feedback. Thematic analysis revealed five main themes: producers on the defense, distrust of program, return on investment, anger, and nostalgia. Of respondents, 50.0% identified dairy co-ops or processors as the main source of information about FARM, and 73.6% reported being knowledgeable about FARM. More formal education and larger herd size were correlated with greater producer knowledge (P < 0.01 and P = 0.04, respectively). More producer input in the revisions of FARM was identified as a need by 83.3% of respondents. While 89.3% of respondents reported positive experiences with evaluations and relationships with evaluators, 45.6% did not think that FARM has value overall. Females had a neutral impression of the value of the FARM program and males had a negative impression (P = 0.02). Greater respondent age was predictive of greater perceived value of FARM (P < 0.01). Age was significant in determining the reasons for considering FARM important (P < 0.01). Odds that respondents described FARM as important because it improved animal health and wellbeing over describing FARM as not important increased 7.2% (OR = 1.072; 95% OR CI: 1.024, 1.122) with each year of age. As age increased, respondents were more likely to describe FARM as important because it unified the dairy industry on animal welfare over describing FARM as not… Advisors/Committee Members: Román-Muñiz, Ivette N.

▼ Interest in Management-intensive Grazing (MiG) on irrigated, perennial, cool-season pasture has increased steadily in Colorado due to pressure to reduce public lands grazing, overall declining space available for pasture, and declining commodity prices. However, there are still many unknowns about how forage production, forage quality, plant diversity, and soil quality are affected by this management over the long-term. To investigate potential effects on these variables, a study was undertaken on a full-scale, 82 ha, center pivot-irrigated, perennial pasture that had recently been planted with four different species mixtures at the Colorado State University Agriculture, Research, Development and Education Center located 13 km northeast of Fort Collins, CO. During the first one and a half years of production, approximately 230 animal units (AUs) consisting of cow-calf pairs, yearling heifers, and yearling steers were grazed using management-intensive practices. Paddock size was dynamic and determined based on number of animals and forage availability with animals generally moved daily. Forage yield and quality, botanical composition and cover, animal unit days (AUDs), and soil quality parameters were measured. In both 2017 and 2018, species mixtures that were either hayed or grazed first in the rotation induced vegetative regrowth resulting in the greatest quality. Quality remained high enough through the grazing season to meet cattle nutrient requirements regardless of the species mixture. There was no significant difference between seasonal mean yields in 2017. The simple grass-legume mixture resulted in the greatest seasonal mean yield in 2018 with 3916 kg/ha-1 but the complex grass mixture resulted in greatest AUDs (7493.93 AUDs). Bare patches developed around patches of non-soft leaf tall fescue (Festuca arundinacea Shreb.) in this mix, which made it evident that cattle were selecting against this type of tall fescue. Botanical composition assessments did not align with the initial seeding rates in some cases, which suggests soil conditions, plant phenology, and competitive advantages contributed to differences between seeded and established composition of the mixtures. Ground cover showed that litter was similar among species mixtures that were planted and grazed earlier compared to the species mixture that was not. Mean plant cover (23.75%) was similar among all mixtures. Soil analysis included 11 biological, chemical, nutrient, and physical parameters that were aggregated into the Soil Management Assessment Framework (SMAF) program resulting in soil quality index (SQI) values. Positive soil quality effects were observed in the biological SQI with increases in microbial and enzymatic activities. Soil organic carbon remained relatively unchanged. Negative impacts occurred to the soil physical SQI, driven primarily by increasing bulk density. The nutrient SQI value declined due to the observed reduction in extractable soil P due to low concentrations occurring in multiple soil samples; similar observations… Advisors/Committee Members: Brummer, Joe (advisor), Ippolito, James (committee member), Ahola, Jason (committee member), Rhoades, Ryan (committee member).

▼ In horses, determination of certain genetic traits/alleles in embryos before embryo transfer would be advantageous due to the costs of resulting pregnancies. An attractive option is preimplantation genetic diagnosis (PGD), but to date few biopsied equine embryos have resulted in pregnancies. In the current experiment, 37 embryos ranging from 160 - 575 μm in diameter were biopsied. To obtain embryos, donor mares were monitored using transrectal ultrasonography. When a follicle > 35 mm in diameter was observed, 2,500 IU hCG or 1.5 mg deslorelin acetate was administered, and mares were inseminated daily until ovulation was detected. Embryos were recovered nonsurgically on days 6.5 – 7 (day 0 = ovulation). Trophoblast biopsies were collected in a 30 μl droplet of Syngro Holding Medium (Bioniche, Belleville, ON) using a piezo drill and beveled injection pipette. After removal of the embryo, the droplet containing the biopsied cells was moved into an Eppendorf tube and centrifuged. Supernatant was removed leaving ~5 μl sample, which was snap frozen for later genetic testing. Fifteen biopsied embryos were immediately transferred nonsurgically into uteri of synchronized recipients. Day 16 pregnancy rate for embryos ≤ 300 μm was 75.0% (6 of 8; 175 – 240 μm), which was not significantly different from control embryos of the same size (77.3%; 17 of 22). For embryos > 300 μm, day 16 pregnancy rate was 28.6% (2 of 7; 320 and 400 μm), which was not significantly different from control embryos of the same size (62.5%; 10 of 16). Additionally, 22 embryos (150 - 440 μm) were vitrified by standard procedures after biopsying and later warmed and transferred directly. No embryos > 300 μm (n = 3) became pregnancies after vitrification. Day 16 pregnancy rate for ≤ 300 μm was 47.4% (9 of 19; 150 – 225 μm), which was significantly different (p < 0.05) from direct transfer and control embryos of the same size (75.0% and 77.3%, respectively). Three of these pregnancies (150 - 200 μm) resulted in the formation of empty trophoblastic vesicles by 25 d. All pregnancies were terminated on or after 25 d to collect embryos for further genetic testing. For preimplantation genetic testing, a duplex nested polymerase chain reaction (PCR) was developed for amplification of the DNA from the biopsied cells using primers for sex chromosome-linked zinc finger protein genes (ZFx/ZFy; 445 bp), and 2 pairs of primers for equine-specific sex-determining region on the Y-chromosome (SRY; 217 bp, 121 bp). Experiments on XX and XY genomic DNA from white blood cells revealed accurate genetic testing on as little as ~9 pg DNA, which equals ~1 cell. Sex determination on biopsied material occurred for 30% of samples, one of which was confirmed from a placental sample. Low PGD results indicate either lack of sensitivity of the test, or more likely the loss of cells during the steps of transfering the biopsied cells to Eppendorf tubes. We concluded that biopsy collection, preimplantation genetic diagnosis, and direct transfer can be performed on equine embryos without… Advisors/Committee Members: Seidel, George Jr. (advisor), McCue, Patrick (advisor), Ahola, Jason K.
