摘要
试验研究了发酵葡萄渣颗粒饲料对育肥牛生产性能的影响。选择26头平均体重为304 kg左右的西门塔尔杂种牛,按体重和性别随机分成2个处理组,每组13头,对照组日粮组成为自配肉牛精料补充料+青贮饲料+干草,试验组日粮组成为发酵葡萄渣颗粒饲料+青贮饲料+干草,试验期为60 d。试验结果表明,与对照组相比,育肥牛饲喂发酵葡萄渣颗粒饲料,日增重提高了5.89%(P<0.05),料重比降低了2.79%(P>0.05),头均毛利润提高了58.24元,经济效益提高了4.17%。
The effects of fermented grape slag particle feed on the production performance of fattening cattle were studied. 26 Simmental Hybrid Cattle with the average weight of about 304 kg were randomly divided into two groups （with 13 cattle in each group）. The diet composition in control group was as follows：self-made concentrate supplier of beef cattle, silage and hay. The diet composition in test group was as follows：fermented grape slag particle feed, silage and hay. The test period lasted for 60 days. The results showed that the daily weight gain of fattening cattle that was fed with fermented grape slag particle feed was increased by 5.89%（P〈0.05）. And the feed-gain ratio was decreased by 2.79%（P〉0.05）. The average gross profit increased 58.24 yuan and the economic benefit increased by 4.17%.
