Liveweight Gain Of Lambs Grazing Six Short-Term Ryegrass Cultivars, W. W. Nichol, M. G. Norriss
Liveweight Gain Of Lambs Grazing Six Short-Term Ryegrass Cultivars, W. W. Nichol, M. G. Norriss
IGC Proceedings (1997-2023)
Increasing dry matter (DM) production per ha is a key goal in ryegrass (Lolium) breeding programmes (Easton et al., 2002), based on the assumption that increased DM yield will in turn increase profitability per ha, through an increase in animal productivity. However, the performance of animals grazing pasture can also be modified by the quality of the forage on offer, and the presence of toxins within the pasture. The objective of this study was to compare the liveweight gain per hectare of lambs grazing six short-term ryegrasses, which had been selected for various combinations of improved DM …

Investigating Cause-Specific Mortality Of Sheep To Determine The Impacts Of Carnivores On Domestic Livestock, Nathan Jacob Floyd
Investigating Cause-Specific Mortality Of Sheep To Determine The Impacts Of Carnivores On Domestic Livestock, Nathan Jacob Floyd
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Livestock and carnivores interact in ways that are considered conflict throughout the world. In the western United States, livestock are often grazed on public lands in close proximity to predators in their natural habitat, and can be killed as prey. Livestock losses to predators can threaten rancher’s livelihoods. Sheep and lambs are especially vulnerable to predators due to their small size and lack of defensive abilities. To reduce the impacts that predators have on livestock, it is important for ranchers and wildlife biologists to have an accurate understanding of how many livestock die and are killed by predators when grazing …

Model Definition For Genetic Evaluation Of Purebred And Crossbred Lambs Including Heterosis, Napoleón Vargas Jurado, David R. Notter, Joshua B. Taylor, Daniel J. Brown, Michelle R. Mousel, Ronald M. Lewis
Department of Animal Science: Faculty Publications
Crossbreeding is a common practice among commercial sheep producers to improve animal performance. However, genetic evaluation of U.S. sheep is performed within breed type (terminal sire, semi-prolific, and western range). While incorporating crossbred records may improve assessment of purebreds, it requires accounting for heterotic and breed effects in the evaluation. The objectives of this study were to: 1) describe the development of a paternal composite (PC) line, 2) determine the effect of direct and maternal heterosis on growth traits of crossbred lambs, 3) estimate (co)variance components for direct and maternal additive, and uncorrelated maternal environmental, effects, and 4) provide an …

In the 35-week-long growth trial, the animals were divided into 4 groups (n = 5) and fed 2 dietary treatments: a basal diet (35:65 roughage and concentrate) or a basal diet supplemented with 4% NaHCO_3. Twelve lambs randomly selected from this trial were arranged in a 2 × 2 factorial design for a 10-day-long slaughter and carcass evaluation experiment. Lambs in …
Adaptation Of Lambs To An Endophyte Infected Tall Fescue Seed Diet, Rachel Ann Rickly Zinner
Adaptation Of Lambs To An Endophyte Infected Tall Fescue Seed Diet, Rachel Ann Rickly Zinner
Theses and Dissertations--Animal and Food Sciences
Ten wether lambs were used to determine the effects of ergovaline consumption from endophyte infected tall fescue, on nutrient utilization and metabolism. Lambs were fed a diet of 23% endophyte free tall fescue seed (E-) and 77% concentrate from d -14 to -1 (adaptation phase). On d 0, five lambs were switched to an endophyte infected seed diet (E+) where they remained through d 14. Nutrient digestibilities tended to increase from adaptation through the acute (d 1 to 4) to subacute (d 10 to 14) phases when E- was fed. E+ digestibilities were highest (P < 0.05) in the acute phase. Lambs fed E+ had higher rectal temperatures in the acute (P < 0.01) and subacute phases (P < 0.05). Fecal recovery of ergovaline increased as day of collection increased in the acute and subacute phases. Lysergic acid fecal recovery increased with day of collection in the acute phase, but no effect was found in the subacute phase. Serum enzyme analyses did not indicate tissue damage from alkaloid consumption. These results demonstrate lambs try to adapt to endophyte infected fescue seed consumption through increased nutrient digestibilities and increased ergovaline and lysergic acid excretion.

Over a 2-year period, crossbred lambs resulting from the mating of Texel (T), Romanov (R), and St. Croix (S) rams with Polypay (P) and S ewes, were finished during the summer and late fall to determine feedlot performance and carcass characteristics. A total of 175 wether lambs of the five genotypes (R x P, R x S, S x S, T x P and T x S) were fed a high-energy diet for an average of 110 d (Experiment 1). Purebred St. Croix lambs weighed less (P < 0.05) at the beginning and end of the finishing period, had the lowest average daily gain (ADG) (P < 0.05), and the lowest Gain:Feed (P < 0.10) of the five genotypes evaluated. All five genotypes produced carcasses with a quality grade ≥ Choice. In a subsequent 2-year experiment (Experiment 2), 251 lambs sired by either Dorset or St. Croix rams from the ewes created in Exp.1 were used. Dorset-sired lambs were heavier (P < 0.10) at the end of the feeding period and had greater ADG (P < 0.10) than lambs sired by St. Croix rams. Wether lambs were heavier (P < 0.10), grew faster (P < 0.10) and ate more (P<0.05) feed than female lambs. Lambs from crossbred ewes were heavier (P <0.05) at the beginning and end of the finishing period and grew faster (P < 0.10) than lambs from purebred St. Croix ewes. When Dorset rams were used as the terminal sire, lamb feedlot performance was similar among the five ewe genotypes used in this study.
