Testing Intervention Strategies To Reduce The Prevalence Of Lung Lesions In Lambs, Jay A. Daniel, Jeff E. Held
Testing Intervention Strategies To Reduce The Prevalence Of Lung Lesions In Lambs, Jay A. Daniel, Jeff E. Held
South Dakota Sheep Research Reports, 2006-07
We have previously demonstrated that lung lesions decrease average daily gain in lambs. We have also observed fall born lambs have a lower prevalence of lung lesions than spring born lambs. The different prevalence in lung lesions between spring and fall born lambs suggests that lung lesions can be prevented. Mannheimia (Pasteurella) haemolytica and/or Pasteurella multocida are present in lambs with moderate or severe lung lesions, but not in lambs with normal lung tissue. In serial slaughter studies, we observed lung lesions formed post-weaning. Therefore, we designed two studies to test possible intervention strategies to reduce the prevalence or severity …
The Effect Of Corn Or Soybean Hull Diets Supplemented With Dried Distillers Grain With Solubles (Ddgs) On Finishing Lamb Performance And Carcass Merit, Rob Zelinsky, Jay A. Daniel, Jeff E. Held
The Effect Of Corn Or Soybean Hull Diets Supplemented With Dried Distillers Grain With Solubles (Ddgs) On Finishing Lamb Performance And Carcass Merit, Rob Zelinsky, Jay A. Daniel, Jeff E. Held
South Dakota Sheep Research Reports, 2006-07
Eighty 78.1 ± 1.6 lb white-faced and brockle-faced wether and ewe lambs were used in an experiment to test the effects of soybean hulls and dried distillers grains with solubles (DDGS) on growth, feed efficiency and carcass merit. Lambs were placed on test between 79 to 105 days of age (average 92 days) and fed the experimental diets for 60 days. Each pen consisted of 10 lambs. Diets were formulated to meet or exceed NRC requirements. The diets were corn or soybean hull based and DDGS served as the protein supplement in both diets. No treatment differences were observed in …
Shearing Lambs Improves Growth Performance During Periods With Elevated Thermal Load, Jake J. Herrig, Simone M. Holt, J.A. Daniel
Shearing Lambs Improves Growth Performance During Periods With Elevated Thermal Load, Jake J. Herrig, Simone M. Holt, J.A. Daniel
South Dakota Sheep Research Reports, 2006-07
The purpose of this study was to determine if average daily gain (ADG) is improved in shorn lambs versus non-shorn lambs in the summer months in the upper Midwestern United States. Forty-nine purebred Hampshire and Columbia ram (n = 10 Hampshire and 4 Columbia) and ewe (n = 22 Hampshire and 13 Columbia) lambs were grouped by breed, sex, age (104 ± 1.7 days of age), and initial weight (109 ± 3.5 lbs) into shorn (n=26) and non-shorn (n=23) groups. After shearing (3 June 2004), shorn sheep had approximately 0.1 inches of wool-cover. Lambs were weighed 1, 29, and 57 …
