| influence of yeast culture supplementation and advancing season on steers grazing mixed-grass prairie in the northern great plains: i. dietary composition, intake, and in situ nutrient disappearance. | twelve beef steers (368 +/- 25.3 kg) and four beef heifers (559 +/- 79.5 kg) fitted with ruminal cannulas were used to evaluate effects of yeast culture (yc) and advancing season on dietary chemical composition, intake, and in situ cp and ndf degradation. treatments were control and yc supplementation (28.4 g.steer-1.d-1 dosed ruminally). steers grazed from late june to early november 1991 on mixed-grass prairie. experimental periods consisted of 10 d for adaptation and a 13-d collection phase. ... | 1994 | 7982846 |
| influence of yeast culture supplementation and advancing season on steers grazing mixed-grass prairie in the northern great plains: ii. ruminal fermentation, site of digestion, and microbial efficiency. | twelve ruminally and duodenally cannulated beef steers (initial bw 368 +/- 25.3 kg) and four ruminally cannulated beef heifers (initial bw 559 +/- 79.5 kg) were used to evaluate the effects of yeast culture (yc) and advancing season on ruminal fermentation, microbial protein synthesis, ruminal fluid kinetics, and site of digestion. treatments were control and yc supplementation (28.4 g.steer-1.d-1 dosed ruminally). steers grazed from late june to early november 1991 on mixed-grass prairie. rumin ... | 1994 | 7982847 |
| microbial loads, mycotoxins, and quality of durum wheat from the 2001 harvest of the northern plains region of the united states. | the 2001 durum wheat crop grown in the northern plains was surveyed for microbial loads, mycotoxins, and quality. correlations among these factors were identified. effects of cleaning, milling, and pasta processing on microbial loads and deoxynivalenol (don) concentrations were determined. aerobic plate counts (apcs), mold and yeast counts (mycs), internal mold infection (imi), and internal fusarium infection (ifi) were lowest in grain samples from montana and highest in grain from northeastern ... | 2004 | 15083730 |
