摘要
利用普那菊苣青绿叶片配合精料育肥三元杂交肉猪,经过105 d的育肥,在5 个不同搭配组合中,当青料干物质占日粮干物质的25.96%时,头日均增重最快,为692.12 g;瘦肉率较高,为63.78%,与对照差异达极显著(P<0.01);屠宰率为74.06%,饲料转化率为3.02 kg,比对照低,但成本减少61.93元,效益增加60.19元;经济效益最高,为173.36元,与其他几个组合差异极显著(P<0.01),是一个比较理想的搭配组合,可直接用于生产推广。
In this study, the effects of five combinations of fresh Puna chicory and ration feed on the pigs of three breed hybrid were compared after 105d feeding. When the amount of fresh Puna chicory dry matter added into feed was 25.96%, the average (increased) weight was highest reaching 692.12g per day. The lean meat rate was 63.78%, it was higher, getting (significant) (difference) compared with the check group (P<0.01). Its slaughter rate was 74.06%, the feed transforming index was 3.02 kg, lower than the CK group. But it saved 61.93 RMB of cost, its economic profits added 60.19 RMB. That was the highest and reached 173.36 RMB each pig. Therefore, this feed combination was more rational for feeding pigs of three breed hybrid and it was worthy of (extension).
