传统饲喂方式与TMR饲喂方式对舍饲犏雌牛产乳性能的影响

Research on the Effects of Milk Production Performance of Barn Feeding Breeding Female Pianniu Between the Traditional Feeding Way and the Way of Feeding TMR

[目的]为证明TMR饲喂方式对犏雌牛产乳性能的影响,增加产奶量和改善牛奶品质。[方法]按照产奶量,胎次,泌乳日龄相近的原则,选择10头泌乳盛期经产犏雌牛,采用完全随机试验设计,分为试验组和对照组(n=5)。试验组犏雌牛饲喂TMR饲料,对照组采用精粗分开的传统饲喂方式。[结果]试验表明,试验组犏雌牛干物质采食量比对照组提高1.87%,平均日产奶量提高0.35kg,差异显著(P<0.05),平均乳脂率高0.43%,乳蛋白高0.17%,但差异性不显著(P>0.05)。[结论]TMR饲喂全舍饲养殖犏雌牛有效地提高了饲料的利用率,降低了饲养成本,探索和寻找出了一套适合甘南州犏雌牛生产的饲养管理模式。。

【Objective】The application of TMR feeding female Pianniu in Gannan farming-pastoral zone can effectively guarantee the female Pianniu to gather the food nutrition balance,improve the dry matter intake,thereby increasing production and improving the quality of milk.【Method】According to the similar principle of milk yield,parity and lactation days of age,choice 10 lactating multiparous cattle,using a completely randomized design,divided into the experimental group and the control group（n = 5）.The experimental group fed TMR feed,the control group fed in the tradition way.【Result】The test results showed that the dry matter intake of experimental group increased by 1.87% than that of control group,and the average daily milk yield increased by 0.35 kg than the control group,which had a significant difference（P〈0.05）.The milk fat rate and milk protein in experimental group was higher than the control group by 0.43% and 0.17%,respectively,but the difference was not significant（P〉0.05）.【Conclusion】The TMR feeding could improve the feed utilization rate of female Pianniu,which also reduce feed costs and explore a suitable feeding and management model for Pianniu.
