Feedlot Performance And Carcass Traits Of Cull Cows Fed For Slaughter, R. H. Pritchard, P. T. Burg
Feedlot Performance And Carcass Traits Of Cull Cows Fed For Slaughter, R. H. Pritchard, P. T. Burg
South Dakota Beef Report, 1993
This trial was designed to evaluate how various factors impact the value added process of feeding cull cows. Specific management criteria evaluated included initial body condition, days on feed, implants, and cow age. Feedlot performance and carcass trait changes due to these factors were compared. Prolonging the feeding period from 50 to 77 or 105 days tended (P=.10) to increase average daily gain and dry matter intake (P<.01) and had no (P>.15) effect on feed/gain. This response is similar to short term adaptation and feeding of young cattle. Added days on feed increased (P<.001) dressing percentage, ribeye area, and ribfat thickness while decreasing (P<.001) lean age. Days on feed did not improve fat color. Older cows gained slower (P<.001) and were lighter muscled than young cows. Longer feeding periods progressively increased the number of high quality carcasses produced.
Role Of Supplement Form For Finishing Yearling Steers, R. H. Pritchard
Role Of Supplement Form For Finishing Yearling Steers, R. H. Pritchard
South Dakota Beef Report, 1993
The impact of liquid, meal, and pelleted supplements on feedlot performance and liver abscesses was evaluated in yearling steers. Steers were fed 90% concentrate diets and test supplement sources for 105 days. The control diet included all supplemental feed ingredients in pelleted form. Four other diets included a liquid supplement that contained supplemental vitamins, minerals, and monensin and a dry supplement providing protein and tylosin all equal to the control. The protein-tylosin component was fed in meal or pelleted form. Overall, steers fed liquid supplements outperformed steers fed dry pelleted supplements with higher average daily gain (P=.05) and dry matter …
