Effects Of Various Concentrations Of Soybean Hull Supplementation On Performance, Digestion And Serum Chemistry Of Weaned Beef Cattle Fed Ryegrass Baleage, Paige N. Tipton
Theses and Dissertations
Graded concentrations of soybean hull pellets (SHP) fed to calves consuming annual ryegrass baleage was evaluated in two experiments. Experiment one evaluated performance and serum glucose of animals fed three treatments. Treatments were: 0.0% (TRT 0), 0.5% (TRT 0.5), 1.0% (TRT 1) body weight (BW) of SHP fed daily while calves had ad libitum access to baleage. Average daily gain and BW increased for calves receiving TRT 1 (P < 0.05). Experiment two evaluated passage rate of treatments using ytterbium chloride as a marker. Passage rate of diet decreased for TRT 1 compared to TRT 0 (10.9 h vs. 16.72 h TRT 1 and TRT 0 respectively, P < 0.05). Calves receiving TRT 0.5 had greater ADG than calves fed TRT 0 (0.54 kg/d and 0.30 kg/d respectively; P < 0.05). Diet passage rate decreased as supplement amount increased (P < 0.05). Serum glucose concentrations were not affected.
An Evaluation Of The Effects Of Annual Ryegrass Cytotype On Herbage Mass, Nutritive Value, And Cattle Performance, Sarah Marie Montgomery
An Evaluation Of The Effects Of Annual Ryegrass Cytotype On Herbage Mass, Nutritive Value, And Cattle Performance, Sarah Marie Montgomery
Theses and Dissertations
Annual ryegrass (Lolium multiflorum Lam.) can be divided into two cytotypes: diploid (2n = 2x = 14) or tetraploid (2n = 4x = 28). Transforming annual ryegrass from diploid to tetraploid often results in increased seedling vigor, more robust growth and, thus, supposedly greater yield. There has been conflicting research that suggests no difference in yield between diploid and tetraploid cultivars, but livestock producers’ question whether benefits exist to utilizing tetraploid cultivars for grazing cattle. This study sought to determine if annual ryegrass cytotype affected cattle average daily gain. Although there were no differences in average daily gain between cytotypes, …
