摘要
试验选取 4月龄的海门山羊 2 4只作为试验动物 ,随机分为三组 :试验 组 ( )、试验 组 ( )、对照组 (CK ) ,每组 8只 ,对其进行饲养试验 ,试验期 40 d,研究复合营养舔砖对山羊的增重速度和经济效益的影响。结果表明 :(1)补饲 号舔砖的试验 组平均日增重 3 9.75 g,补饲 号舔砖的试验 组平均日增重 40 .5 0g,分别比对照组 2 6.0 0 g提高 5 2 .88% (P<0 .0 5 )、90 .3 8% (P<0 .0 1) ;(2 ) 、 组比对照组实际净增纯利2 8.3 0、5 1.2 3元 ,增收率分别为 42 .5 2 %、76.97% ,每只羊平均每天比对照组多获利 0 .0 9、0 .
By feeding experiments, studies are made to test multinutrient blocks effect on goats growth rate and economic benefits. In this experiment, twenty four Haimen goats with four months are freely divided into three groups: the experimental group Ⅰ(Ⅰ), the experimental group Ⅱ(Ⅱ), and the controlled group (CK). The results showed: (1) The group fed with multinutrient Ⅰ block gains weight 39 75 g per day and the group fed with multinutrient Ⅱ block gains weight 49 50 g per day, 52 88%( P <0 05) and 90 38%( P <0 01) fast than that of the CK group 26 00 g per day; (2)Ⅰ?Ⅱ group bring more profit, 28 30?51 23 yuan, than the CK group with 42 52% and 76 97%. Multinutrient block Ⅰ and Ⅱ bring to feeders 0 09?0 16 yuan more in profit per day with a goat.
