Effect of timed interval frequent feeding of predominantly corn silage rations to beef steers.
C ORN silage is being utilized in increased quantities in beef cattle growing and fattening rations. The research data of Hammes et al. (1964), with various ratios of corn to corn silage in fattening rations, have demonstrated that higher levels of corn silage can be justified because gains between high grain and high silage rations are similar, whereas, use of higher silage rations permits the...
متن کاملEffects of Sorting Steers by Body Weight into Calf-Fed, Summer Yearling, and Fall Yearling Feeding Systems
Two years of data (288 steers/yr) were used to determine if sorting cattle by BW into different production systems would decrease overweight carcasses (>431 kg) and hot carcass weight (HCW) variation. At receiving, steers were assigned randomly into sorted or unsorted groups (n = 144 steers/group). Within a group, steers were assigned to 1 of 3 feeding times: 1) calf-fed (entering the feedlot a...
متن کاملEffect of Sorting and Feeding Optaflexx on Performance and Economics of Long Yearling Steers
A two-year experiment evaluated the effects of sorting long yearling steers by initial feedlot BW and supplementing 200 mg/steer of Optaflexx daily the last 28 days of the feeding period on ADG, F/G, carcass characteristics and profitability. Feedlot ADG, F/G, and profitability were not effected by sorting. However, sorted cattle exhibited increased fat thickness, increased rib-eye area, and in...
متن کاملImpact of sorting before feeding zilpaterol hydrochloride on feedlot performance and carcass characteristics of yearling steers.
Two studies evaluated sorting and feeding zilpaterol hydrochloride (ZH) on feedlot performance and carcass characteristics in randomized block-designed finishing trials. In Exp. 1 (initial BW 342 ± 10 kg, = 1,000), 5 treatments included an unsorted non-ZH fed negative control (-CON), an unsorted ZH fed positive control (+CON), and 3 treatments in which the heaviest 20% within the pen were sorte...
متن کاملSocial models fail to induce diet and feeding site avoidance in naïve yearling steers.
Social learning can be of critical importance to cattle grazing rangeland environments with high variability of food resources across space and time. Experienced individuals can greatly facilitate foraging decisions (what to eat and where to eat) of naïve peers in such settings. We conducted an experiment with cattle to investigate strength and persistence of socially induced food and feeding s...
