湿玉米纤维饲料对奶牛瘤胃发酵和产奶性能的影响
Effect of Wet Corn Gluten Feed on Rumen Fermentation and Milk Performance of Lactating Dairy Cows
摘要
Abstract
This study was conducted to investigate the effect of feeding different addition levels of WCGF on ruminal fermentation traits and to test the animal performance in high producing dairy cows.Experiment 1,effects of feeding different additional levels of WCGF on rumen fermentation in dairy cows,four non-lactating Holstein dairy cows fitted with permanent rumen fistula were used in a 4×4 Latin square designed trial.Each animal was fed one of four treatment diets during each period:0% (control),15%,25% and 35% WCGF on a dry matter basis.The results showed that the concentrations of ruminal ammonia and acetate were increased as the level of WCGF increased (P<0.05).Acetate:propionate (A:P) was significant decreased (P<0.05).Experiment 2,effects of feeding WCGF on production performance in high producing dairy cows,sixty high producing dairy cows were selected and used in a single factor randomized design experiment to evaluate the effects of feeding WCGF (25%DM) on production performance of high producing dairy cows.The results showed that the milk production was significant reduced by 2.65% but the milk fat percentage of cows was increased.(P<0.05).It was concluded that:the feeding ratio should not be higher and feeding 25% WCGF could reduce the milk production,but could but increase the milk fat percentage.关键词
