Dietary roughage regimen for feedlot steers: reduced roughage level (2%) during the mid-finishing period.
Because roughage in feedlot diets is one of the most expensive ingredients on an energy basis, regimens that minimize roughage usage are of interest. Crossbred steers of British breeds (n = 112, initial BW = 405 kg) were used to compare the feeding of diets containing 2% roughage from d 22 through 84 and 10% roughage from d 85 to finish (d 133; 2/10%) to the feeding of 10% roughage throughout t...
متن کاملEvaluation of Wet Distillers Grains in Finishing Diets for Yearling Steers
A feeding trial was conducted with 940-lb yearling steers fed 113 days to determine the feeding value of distillers grains relative to corn grain. Replacing corn and urea with wet distillers grains for 20% of the diet dry matter tended to increase gain with no increase in feed consumption, resulting in improved feed conversion. Replacing 40% of diet dry matter with wet distillers grains decreas...

متن کاملFeedlot Closeouts for Holstein Steers
Feedlot closeout data is an important tool for measuring cattle performance and management practices for cattle production systems. Often, closeouts are quickly scrutinized by feedlot managers and cattle owners for economics and typical performance measurements and then filed. Unfortunately, a plethora of data that is reported in closeout reports is never adequately analyzed. A dichotomy of dat...
متن کاملInfluence of level and source of dietary fat on its comparative feeding value in finishing diets for feedlot steers: metabolism.
Six crossbred steers (315 kg) with cannulas in the rumen, proximal duodenum and distal ileum were used to study the influence of level and source of dietary fat on characteristics of digestion. Dietary treatments consisted of a steam-rolled barley-based finishing diet containing 1) no supplemental fat; 2) 4% yellow grease (YG); 3) 4% blended animal-vegetable fat (BVF); 4)8% YG; 5) 8% BVF or 6) ...
