摘 要:将32只3.5~4月龄波萨安杂交羊按体重相近原则分为4组,分别补饲精料300、550、800和1050g/只.d,并且自由采食干黄豆秸,以研究不同精料补饲量对波萨安杂交羊育肥效果的影响。结果表明:试验期平均日增重分别为66.61±18.34、133.39±26.32、156.03±32.45和164.01±31.87;随着精料量的增加,粗料采食量呈下降趋势,日粮总采食量呈上升趋势。本实验表明,在粗饲料自由采食条件下,波萨安杂交羊精料最佳补饲量为550g/只.d,此时粗料采食量为723.52g,精粗比为43:57,体重每增加1kg饲料费最低(6.74元/kg.只),盈利最高(21.75元/只)。These 32 Boer×Saanen×Anhui white Goats(3.5~4 months old) divided into 4 groups according to the similar weight.Feeding concentrate 300,550,800 and 1050 g /only·d respectively with dried beanstalk freely.Study on the Study on the effect of fattening Boer×Saanen×Anhui white Goats with different Concentrate Addition Feeding Amounts.The result showed that,average daily gain of he trial period were 66.61 ± 18.34、133.39 ± 26.32、156.03 ± 32.45 and 164.01 ± 31.87g;along with the amount of concentrate increased,the amount of roughage decreased and the amount of total feed intake rose.This experiment indicated,the best concentrate feed amount of the Boer×Saanen×Anhui white Goats is 550g/only goat·d,then roughage intake as 732.52g,concentrate to roughage ratio was 43:57,with the weight for each additional 1kg,the lowest feed cost was(6.74yuan·only goat),the highest profit was(21.75yuan/ only).
