摘要
[目的]为了探讨鲜啤酒糟对西门塔尔种母牛产奶量的影响。[方法]选择健康泌乳正常的西门塔尔母牛30头,依据胎次、产奶量、产奶天数分为3组,每组10头。试验A组在基础日粮中加喂鲜啤酒糟10 kg/头.日;试验B组在基础日粮中增加配合精料1.5 kg/头.日;对照组饲喂基础日粮。[结果]表明,试验A、B组头日均增奶3.11 kg、0.23 kg,对照组头日均减奶0.45 kg。试验A组与试验B组、对照组的日增奶量差异极显著(P<0.01);而试验B组、对照组之间显著不差异(P>0.05)。试验A组比对照组头日收入增加7.69元,试验B组减少0.81元。[结论]表明日粮中补充鲜啤酒糟能显著提高西门塔尔种母牛的产奶量与经济效益。
【Objective】To investigate the effect of fresh brewer＇s grains on milk yield of Simmental cows.【Method】30 Normal healthy lactating Simmental cows according to parity,milk yield and milk days were divided into 3 groups,each group had 10.The group A was fed the basal diet with fresh brewer＇s grains 10 kg / head /Day,and group B fed the basal diet with the concentrate 1.5 kg / head /Day.Group C was as the control and fed a basal diet.【Result】The results showed that the milk yield increased by 3.11 kg,0.23kg per cattle at the first day of group A and B,respectively.While the control group reduced by 0.45kg.The difference in milk yield between group A,and group B and the control group was significant（P0.01）;and that between group B and the control group was not significant（P0.05）.Compared with the control group,group A increased by 7.69 yuan,while group B decreased by 0.81 yuan at the first day.【Conclusion】The diet supplement of fresh brewer＇s grains could significantly improve the Simmental cow＇s milk production and types of economic benefits.
