Evaluation of performance, carcass characteristics, and sensory attributes of beef from finishing steers fed field peas.
Whole field peas were fed at 0, 10, 20, and 30% of DM to 139 yearling steers (British cross; 409 ± 31 kg of initial BW) for a 119-d finishing period. Carcass data and Choice grade strip loins (n = 98) were collected from a commercial abattoir in Lexington, Nebraska. Consumer sensory and Warner-Bratzler shear force analyses were performed on 2.5-cm strip steaks. No differences (P ≥ 0.17) were ob...
متن کاملS ta te Transfer with Spin Chains
In the last few decades the idea came up that by making use of the superposition principle from Quantum Mechanics, one can process information in a new and much faster way. Hence a new field of information technology, QIT (Quantum Information Technology), has emerged. From a physics point of view it is important to find ways of implementing these new methods in real systems. One of the most bas...
متن کاملon growth performance and carcass quality of finishing steers 1
A combination of yeast and chromium propionate (Y+Cr) was added to the diets of crossbred finishing steers (n = 504; 402 kg ± 5.76 initial BW) to evaluate impact on feedlot performance and car cass traits. We hypothesized supplementation of Y+Cr would increase growth of feedlot steers. Steers with initial plasma glucose concentrations ≤6.0 mM were stratified by initial BW and randomly allocate...
متن کاملRecombinant bovine somatotropin improves growth performance in finishing beef steers.
The objectives of this study were to determine the efficacy of various doses of rbST on ADG and feed efficiency (FE) and to describe carcass composition changes in finishing beef steers. In Exp. 1, 96 crossbred beef steers (393 kg) received daily i.m. injections of buffer or 33, 100, or 300 micrograms/kg of BW of rbST (0ST, 33ST, 100ST, 300ST). In Exp. 2, 200 crossbred beef steers (417 kg) rece...
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...
