不同添加物对生长肥育猪的效果研究

EFFICIENCY OF DIFFERENT ADDITIVES FOR GROWING FINISEING PIGS

本文研究了不同添加物对40—90kg长白×成华杂交猪生产成绩的影响。结果表明,在饲粮DE13.8MJ/kg,CP13—14％条件下,同时添加0.34％赖氨酸、125ppmCu和250ppm复合抗生素时的生长成绩比单独添加好,全期平均日增重(ADG)为817克,饲料转化率(F/G)为3.23;而经济效益则以只添加125ppmCu时为最高;高氯酸盐(ClO_4^-)与抗生素或赖氨酸合用可进一步改进生产成绩;对生长肥育猪生产成绩的改善,Cu的效果比抗生素好。

The study focused on the efficiency of different additives for the performance of 40—90kg hybrid pigs The results showed that in the diet with DE 13.8MJ/kg and CP 13—14%, the combined supplement of 0.34%lysine, 125 ppm copper and 250 complex antibiotics produced better performance (pigs' average daily gain. 817g, F/G: 3.23) than the separate addition of the three additives, but the addition of the only 125 ppmcopper gained maximum profits, A use of perchlorate together with antibiotics or with lysine could further improve the performance, In promoting growth, copper is more efficient than antibiotics for the fattening pigs.
