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 …

Frost Damaged, Immature Soybeans For Ruminant Diets, J.A. Loesche, R. H. Pritchard, J. M. Reecy
South Dakota Beef Report, 1989
The potential for including freeze damaged, immature soybeans (FDIS) into corn based diets for ruminant animals was evaluated in a series of experiments. No differences in feeding value were evident for FDlS and normal soybeans except due to oil content. Oil content of soybeans depressed dry matter and particularly fiber digestion of corn silage fed to lambs (Pe.05). Nitrogen digestion and retention were also reduced (Pe.10) by feeding raw soybeans. The effect on N utilization appeared to be due to trypsin inhibitor activity, since this did not occur when soybean meal + oil supplements were fed. Nitrogen, dry matter and …

Development Of An In Vivo Model To Determine The Biological Value Of Microbial Protein, T. Fritz, R.H. Pritchard
South Dakota Beef Report, 1986
A semi-purified diet (SPD) was fed to 12 wether lambs and one fistulated wether and evaluated for acceptability and ability to support growth. Ruminal pH and NH3 were monitored throughout the diet adaptation period. Treatments included three levels of dry matter intake; low intake (LI) 750 g-hd-l. d-l, medium intake (MI) 1125 g-hd-l..d-l and high intake (HI) 1500 g-hd-l.d-l. Digestibility of dry matter (DM, 70.6%), acid detergent fiber (ADF, 62.8%), nitrogen (N, 72.8%) and percentage digestible nitrogen retained (33.2%) were not different across intake levels. Indigestible ADF of the semi-purified diet appears to be a suitable solid phase marker for …
