营养舔砖对山羊增重影响的研究

Studies on Effect About Gain in Goat Weight with Nutrional Lapped Bricks

试验用23只波尔山羊与黄淮白山羊杂交一代(以下简称波×黄淮F1)羊,按年龄与体重随机分为对照组和试验1、2、3四个组,各组对应的羊只数分别为6、6、5、6。实验组饲喂相同的舔转,看其对羊增重的影响。结果表明:舔砖对波×黄淮F1代羊有增重作用,其增重作用显著(P<0.05),试验期为30d。实验组每只羊净收益较对照组高2.99元。

Twenty-three boer goats of used experiment is the first filial generation between bore goat and Huanghuai White goat(called boer×huanghuai F1 ).According to age and weight,they are divided into comparision team and experiment 1?2?3team,the amount of each team is6?6?5?6in turn.Experiment teams eating the same blocks,we want to know what they have effect on goat weight.The results show that blocks have some effect about gain in weight on goat,and the effect of weight gain is dominant (P<0.05),experiment time lasts thirty days.The net profit of every goat in experiment teams is RMB2.99yuan higher than comparision teams.
