Effect of aflatoxin in growing lambs fed ruminally degradable or escape protein sources.
Thirty-two crossbred (Suffolk x Rambouillet) wether lambs were used to examine the effectiveness of protein source (soybean meal [SBM] or fish meal [FM]) in alleviating decreased performance associated with dietary aflatoxin (AF) in growing lambs. After a 21-d adaptation period to concentrate diets, lambs were assigned to the following dietary treatments: 1) SBM, 0 mg of AF; 2) FM, 0 mg of AF; ...
متن کاملEffect of energy source and ruminally degradable protein addition on performance of lactating beef cows and digestion characteristics of steers.
Two trials were conducted to determine the effect of energy source (ENG) and ruminally degradable protein (RDP) on lactating cow performance and intake and digestion in beef steers. In Trial 1, 78 cow-calf pairs were used in a 2 x 2 factorial design to determine the effect of ENG (corn or soyhulls; SH) and RDP (with our without sunflower meal) to a forage diet for lactating beef cows. The basal...
متن کاملIntestinal supply of amino acids in steers fed ruminally degradable and undegradable crude protein sources alone and in combination.
The objective of this study was to examine the effect of combining ruminally degradable and undegradable CP sources on ruminal microbial protein synthesis and postruminal N and amino acid (AA) flows in steers. Six steers fitted with ruminal, duodenal, and ileal cannulas were fed diets containing corn silage and high-moisture corn supplemented with urea, soybean meal (SBM), dry corn gluten feed ...
متن کاملEffect of degradable intake protein level on finishing cattle performance and ruminal metabolism.
Two finishing trials and a metabolism trial were conducted to evaluate level of supplemental degradable intake (crude) protein (DIP) in finishing diets on cattle performance, carcass characteristics, and ruminal metabolism. Finishing trials were conducted in two consecutive years using 128 crossbred yearling steers (BW = 343+/-5 kg, Trial 1) and 176 crossbred yearling steers (BW = 375+/-4 kg, T...
متن کاملEffects of Source and Level of Ruminally Protected Choline on Performance and Carcass Characteristics of Finishing Beef Steers
Previous research (Galyean et al., 1997) indicated that daily gain and feed efficiency were improved when finishing beef steers were fed graded levels of ruminally protected choline (RPC; .25, .5, and 1% of dietary DM). Responses were cubic (P < .10) in nature, with an 11% increase in daily gain and a 6.8% improvement in feed efficiency for .25% RPC vs the control diet, but no effect on gain or...
