摘要
试验选用104只阿尔巴斯白绒基础母山羊,在产绒量相同的基础上,用配对分组的方法分成对照组和试验组(每组52只)。然后将试验组又随机分为试验Ⅰ组和试验Ⅱ组。对照组补饲 BS(玉米187.5g+麻饼62.5g+食盐2.5g);试验Ⅰ组补饲 BUS(BS+尿素5g+硫酸钠3g);试验Ⅱ组补饲 BUSM(BUS+蛋氨酸3g)。试验结束,从对照组中找出与试验组相配对的对照Ⅰ组和对照Ⅱ组进行统计分析。结果表明:试验Ⅰ组和试验Ⅱ组的产绒量分别比试验前提高17.67%和19.40%,比其对照组分别提高7.5%和15.56%。试验Ⅱ组的生产效果显著,但经济效益不及试验Ⅰ组。
One hundred and four Downy does were divided into control group and treatment group by paired method(52 heads each group).Subsequently,the treatment group was randomly divided into treatment Ⅰ and Ⅱ The supplem- ents of control group,treatment Ⅰ and Ⅱ were BS(corn 187.5g+lineseed meal 62.5g+salt 2.5g),BUS(BS+urea 5g+sodium sulphate 3g)and BUSM(BUS +methionine 3g),respectively.After finishing trial,statistical analysis was conducted,forming paired control Ⅰ and Ⅱ with treatment groups from control group.The result indicated that the down production of treatment Ⅰ and Ⅱ were 17.67% and 19.4% higher than those before,7.5% and 15.56% higher than those of their control groups respectively.The effect of treatment Ⅱ was significant,but its economical benifit was lower than that of treatment Ⅰ.
