Digestibility of western Canadian finishing beef cattle diets when short-season, high-moisture shelled corn and snaplage partially replace dry-rolled barley grain and barley silage

چکیده
The objective of this study was to determine the effects substituting barley grain with short-season, high-moisture shelled corn, and silage snaplage on ruminal fermentation site extent digestion in beef cattle fed finishing diets. Six ruminally duodenally cannulated heifers (420 ± 16.4 kg body weight) were a diet (BG), where half replaced corn (HC), or portion (SN) replicated 3 × Latin square design. While dry matter starch intake unaffected, feeding SN resulted greater ( P = 0.02) but not total tract digestibility than BG. Ruminal pH did differ between HC BG, reduced minimum relative Feeding BG increased 0.04) ammonia concentrations over HC. In conclusion, can partially replace minimal impact nutrient fermentation, replacement some may increase risk acidosis.

Type and mixtures of high-moisture corn in beef cattle finishing diets.
In three experiments consisting of three finishing trials each, five corn storage and(or) feeding treatments were evaluated: 1) dry whole (DWC); 2) whole high-moisture (WHMC); 3) mixture (MHMC) of ground (GHMC) or rolled (RHMC) high-moisture corn with WHMC; 4) GHMC stored in a bunker silo; and 5) RHMC, corn stored whole but fed in rolled form. In Exp. 1, gains and feed intakes of steers fed who...

The objective was to determine the effect of replacing barley grain and canola meal with high-lipid by-product pellets (HLBP; 14.6% CP, 29.8% NDF, 9.0% fat, and 5.52 MJ NE/kg in DM) on DMI, ruminal fermentation, nutrient flow at the omasal canal, and nutrient digestibility. Four ruminally cannulated and ovariectomized Hereford × Gelbvieh heifers (initial BW of 631.9 ± 23.3 kg; mean ± SD) were u...

The objective of this study was to evaluate the effects of substituting wheat dried distillers grains with solubles (DDGS) for barley grain and barley silage on intake, digestibility, and ruminal fermentation in feedlot beef cattle. Eight ruminally cannulated Angus heifers (initial BW 455 ± 10.8 kg) were assigned to a replicated 4 × 4 Latin square design with 4 treatments: control, low (25%), m...
