摘 要:通过对合成母系各世代猪(F1、F2白系,F2黑系,F4白系,F4黑系)以及互助猪(对照组)的日增重进行比较,发现F4白系和F2的黑白两系日增重均显著高于F1代(P<0.05)),极显著高于F4黑系(P<0.01),F1代显著高于F4代(P<0.05)。平均料肉比除F4代黑系外,基本都在4∶1之内。合成母系与互助猪相比,日增重提高了200g以上,每增重1kg体重耗料降低了1kg以上。以上结果表明,合成母系的生产性能优于互助猪。Daily gain of different generation of composed maternal line of pig (F_1,F_2 white line,F_2 black line,F_4 white line,F_4 black line) was compared with that of Huzhu pig (control group).Daily gain of F_4 white,F_2 white and F_2 black line was significantly greater than that of F_1 generation (P<0.05) and F_4 black line (P<0.01).Daily gain of F_1 generation was significantly greater than that of F_4 generation.The average ratio of feed to meat was about 4∶1 ,except for F_4 black line ,Compared with Huzhu pig, The offspring of composed maternal line of pig had a greater daily gain (more than 200g) and feed conversion rate (saving more than one kilogram feed per one kilogram gain).These results suggested that the performance of composed maternal line of pig was better than that of Huzhu pig.
