摘要
选择14~16个月的体重在150 kg左右的牦牛犊牛40头,按照随机原则将其划分成4个组别,分别命名为试验一组、试验二组、试验三组和对照组,选择使用3种复合营养舔砖投喂试验一组到试验三组的牦牛犊牛,对照组采用常规养殖方式,饲喂90d后对比复合营养舔砖对牛增重及经济效益的影响。研究结果表明,90d的试验期内,试验一组、试验二组、试验三组的日增重分别比对照组提高了33%、43%、51%。每增加1 kg的牛肉消耗的精饲料比对照组少22.60%、23.60%、30.20%,试验组的饲料成本比对照组分别降低了3.70%、5.00%、12.90%。研究结果表明,复合营养舔砖对牛增重有很好的效果,同时还有利于降低养殖成本,提高经济效益,值得在今后的生产中推广应用。
Choose 14~16 months,weight 150 kg of yak calves in a 40 head,in accordance with the principle of random to be divided into four categories,respectively named as test group,experiment group 2,three group and the control group,choose to use three kinds of compound nutrition TianZhuan feeding experiment a set to three groups of yak calves,the control group using conventional breeding methods,The effects of nutritional lick block on weight gain and economic benefit of cattle were compared after 90 days of feeding.The results showed that the daily gain of test group 1,test group 2 and test group 3 increased by 33%,43%and 51%,respectively,compared with the control group during the 90-day experiment period.The consumption of concentrate feed for each increase of 1kg beef was 22.60%,23.60%and 30.20%less than that of the control group,and the feed cost of experimental groups was 3.70%,5.00%and 12.90%lower than that of the control group,respectively.The results showed that the compound nutrition lick block had a good effect on weight gain of cattle,and was also beneficial to reduce the breeding cost.The economic benefit was significant,and it is worth promoting and applying in the future production.
