Feed Utilization By Steers With Chronic Cryptosporidia Infection, R.H. Pritchard, J.U. Thomson, C.D. Mullaney
Feed Utilization By Steers With Chronic Cryptosporidia Infection, R.H. Pritchard, J.U. Thomson, C.D. Mullaney
South Dakota Beef Report, 1990
The effect of chronic cryptosporidia infection on feed utilization by yearling steers was evaluated. Two control and two infected steers were fed a corn silage based diet. lnfected steers had shown evidence of cryptosporidia infection over a 6-month period prior to determining feed digestibility. Digestibilities of dry matter (58.1 vs 54.0 ± 3.9%), NDF (51.7 vs 54.6 ± 2.5%), ADF (35.8 34.8 ± 7.1%) and crude protein (45.0 vs 45.9 ± 5.3%) were unaffected (P>.10) by parasite infection for control and infected steers, respectively.

Whole Plant Faba Bean Siage As A Component Of Growing Steer Diets, J.J. Wagner, H. Nantoume, R. Hanson, D.R. Sorenson
South Dakota Beef Report, 1990
Whole plant faba bean silage was compared to corn-alfalfa silage as a roughage source in 30% roughage growing steer diets. When the proportion of faba bean silage was increased from 0 to 10, 20 and 30%, respectively, daily feed intake, average daily gain and feed conversion of the steers were 18.32, 18.38, 18.23, 19.13 Ib per head; 3.66, 3.42, 3.39, 3.57 Ib per head; and 5.01, 5.38, 5.37 and 5.36, respectively. Substitution of faba bean silage for corn-alfalfa silage in a 30% forage diet had no significant (Pc.05) effect on feed intake, weight gain and feed efficiency for growing steers.
Use Of Sunflower Hulls As The Roughage Component Of Finishing Diets For Yearling Steers, R.H. Pritchard, M.A. Robbins
Use Of Sunflower Hulls As The Roughage Component Of Finishing Diets For Yearling Steers, R.H. Pritchard, M.A. Robbins
South Dakota Beef Report, 1990
Sunflower hulls were substituted for grass-alfalfa hay as the roughage component of finishing diets for yearling steers. Feed intake was lower when sunflower hulls were fed, resulting in reduced rate of gain and increased feed conversion. When diets were formulated to contain 12% NDF rather than 10% roughage, performance of steers fed either roughage source was similar. Sunflower hulls because of low cost can be used in finishing diets at 5% of dry matter intake without affecting production costs. Feeding higher levels of unprocessed sunflower hulls is discouraged.
