摘要
在石门县马头山羊中心产区选择７个试验点共４５个养羊场（户）对复合营养舔砖补饲山羊的效果进行了大群中试。共选用马头山羊２６９５只，随机分组，其中２１２５只补饲舔砖，另５７０只作对照。结果表明：补饲舔砖的羊毛色、膘情显著改观；增重速度较对照组提高３８．２９％（Ｐ＜０．０１）。平均每只试验羊较对照羊每天净增纯收入０．１５２元，补饲舔砖的２１２５只羊在为期９０天的试验期内共净增纯收入２８９００元；补饲舔砖投入产出比达１∶４．８；每吨舔砖可产生直接经济效益２．５万元以上。经济效益、社会效益和生态效益十分显著。
Effects of multinutrient block (MB) on growth rate & economic benifits
of goats were examined in experiment with 2695 goats which were devided into two
groups. The results showed that MB can improve the healthy state of goats. The
average daily Liveweight gain of 2125 goats in the group treated with MB were
increased by 38.29%(P<0.01) over other 570 goats in the control. The net profit get from
per goat in the MB group each day was more 0.152 RMB than that of the control. And
the net profir get from 1000 kilograms MB was more over 25000 RMB. The experiment
indicate that Using MB in goat production is a good way to increase the performances
of goats and to obtain considerable economic benifits.
