Effect Of Finishing System And Animal Age On Carcass Traits And Nutritional Profile Of Bison Bulls, Clay Newton
Effect Of Finishing System And Animal Age On Carcass Traits And Nutritional Profile Of Bison Bulls, Clay Newton
Electronic Theses and Dissertations
The objectives of this thesis project were to 1) evaluate the influence of grain- and grass-finishing systems on carcass characteristics, proximate composition, nutritional profile, and fatty acid composition of bison bull meat, and 2) evaluate the influence of animal age on carcass characteristics of bison bulls. For objective 1, bison bulls were allowed to graze native range in north-central Nebraska until approximately 26 mo of age, when they were randomly assigned to either grain-finishing (n = 98; in an open lot with ad libitum access to prairie hay, alfalfa hay and corn for 95 d prior to slaughter) or grass-finishing …
Effect Of Inoculants On High Moisture Corn Fermentation Characteristics And Cattle Performance, C. P. Birkelo, D. Sorenson
Effect Of Inoculants On High Moisture Corn Fermentation Characteristics And Cattle Performance, C. P. Birkelo, D. Sorenson
South Dakota Beef Report, 1991
High moisture corn was ensiled untreated (treatment 1) or treated with one of three different inoculants (treatment 2 = lactobacillus; treatment 3 = lactobacillus + streptococcus; treatment4 = lactobacillus + serratia), each at two moisture levels (27.2% and 22.4%). lnoculant effects on fermentation were moisture dependent. The pH, acetate concentrations and dry matter losses were generally lower and lactate concentrations higher due to inoculation at 27.2% moisture. Overall, treatment 3 was somewhat more effective than treatments 2 or 4. Inoculation effects were generally less at 22.4% moisture. lnoculant effects on soluble N were small and probably of little nutritional importance. …
Grain Sources And Roughage Levels For Limited Feeding Backgrounding Programs, R. H. Pritchard, M. A. Robbins
Grain Sources And Roughage Levels For Limited Feeding Backgrounding Programs, R. H. Pritchard, M. A. Robbins
South Dakota Beef Report, 1991
The effects of grain source and roughage level in limited intake feeding programs were evaluated in 622-lb steer calves. Supplemented diets were based on high moisture ear corn (HMEC), whole shelled corn (WSC) + hay to provide similar NDF to the HMEC diet, HMEC diet containing 10% hay and the WSC + hay diet formulated to contain NDF similar to HMEC + hay. Steer calves were blocked by weight and fed to achieve 2.2 Ib ADG for a 52-day period. Steers fed HMEC had higher (P<.01) ADG and lower (P<.01) feed/gain than WSC fed steers. Low crude protein in the hay source caused lower (P<.01) crude protein in WSC diets. Lower crude protein intake could have limited steer growth. NE utilization appeared more efficient (P<.05) for heavy weight block steers, reflecting NRC equation low sensitivity to modest differences in frame size. Roughage level did not affect performance and did not interact with grain source.
