半胱胺对皮长大三元杂交猪生产性能的影响

[目的]研究半胱胺作为试验添加剂,对皮长大三元杂交商品猪生长性能的影响。[方法]将皮长大三元杂交猪80头随机分为对照组和试验组,每组40头,且公母各半,探讨在饲料里加半胱胺对猪生产性能的影响。[结果]结果表明,试验组与对照组相比,皮长大三元杂交育肥猪平均日增重提高了6.46%,差异极显著(P<0.01);料肉比降低了4.05%,但差异不显著(P>0.05);经济效益提高了85.64%,差异极显著(P<0.01)。[结论]半胱胺能提高猪的饲料报酬和增重速度,推荐剂量为250 mg/kg。

Effect of the Cysteamine on Production Performance of Skin Long Dasanyuan Hybrid

[Objective]To study effect of the cysteamine as additives on production performance of skin long dasanyuan hybrid pig.[Method] 80 skin long dasanyuan hybrid pigs were divide into two equal groups stochastically,a group appended cysteamine and another group made the control group(CK).Effect of the cysteamine as additives on production performance of skin long dasanyuan hybrid pig was discussed.[Result]The results indicated that the average day by day increase of skin long dasanyuan hybrid pig enhanced 6.46% than control group and the difference was remarkable(P<0.01).Ratio of the material and meat decreased by 4.05%,but difference was not remarkable(P>0.05).Economy benefit increased by 85.64%,having the significant difference(P<0.01).[Conclusion] The cysteamine can enhance feedstuff reward and add weightiness speed of skin long dasanyuan hybrid pig when the additives dosage is 250 mg/kg.
