不同品种全株玉米青贮对泌乳期奶牛生产性能、血清生化指标和瘤胃发酵参数的影响
Effects of different varieties of whole corn silage on production performance,serum biochemical indexes,and rumen fermentation parameters of dairy cows during lactation
摘要
Abstract
The purpose of this experiment was to study the effects of different varieties of whole plant corn silage on the production performance,serum biochemical indexes,and rumen fermentation parameters of dairy cows.In this experiment,30 cows with a body weight of(650.00±36.11)kg were selected and randomly divided into two groups,with 15 replicates per group and one cow per replicate.The control group was fed with Heyu 187 silage,and the experimental group was fed a new variety of whole plant corn silage,respectively.The pre-test period was 15 days and the test period was 60 days.The results showed that there was no significant difference in nutritional quality of whole corn silage between the two varieties(P＞0.05).There were no significant differences in dry matter intake and milk composition between the two groups(P＞0.05).Milk yield,3.5％milk fat correction milk,and feed efficiency of experimental group were significantly higher than those of control group(P＜0.05).The serum β-hydroxybutyric acid content in experimental group was significantly lower than that in control group(P＜0.05).There was no significant difference in rumen fermentation parameters between the two groups(P＞0.05).The study indicates that the feeding effect of the new whole corn silage is better than that of Heyu 187,which is helpful to improve the production performance of dairy cows,and has no adverse effects on the health and rumen fermentation of dairy cows.关键词
