摘要
在马头山羊中心产区选择７个试验点共４５个试验场（户）的２６９５只马头山羊进行了复合营养舔砖的补饲试验。结果表明，补饲了复合营养舔砖的羊，毛色和膘情较对照组明显改观；增重速度比对照组提高了３８．２９％（Ｐ＜０．０１）。平均每只试验羊每天比对照羊净增纯收入０．１５２元，每吨舔砖可产生直接经济效益２．４万元。
The multinutrient block′s effect on goat′s growth rate
and economic benefits is examed with 2695 Matou goats. The results from the
experiments show that weight gain of the goats fed with multinutrient block is 38.29%
(P<0.01) faster than that of the goats in the controlled group. Every goat fed with
multinutrient block brings to feeder 15.2 cents more in profit per day. And every ton of
multinutrient block will output 24000 yuan more in profit.
