高粱日粮中添加复合酶制剂对育肥猪生产性能的影响

Effect of Sorghum Diet Supplemented Multi-Enzyme Additive on Production Performance of Growing-finishing Pigs

本试验旨在研究高粱日粮中添加500 g/t复合酶制剂对生长猪育肥后阶段的生产性能和经济效益有何影响。结果显示:与对照组相比,在高粱日粮中添加复合酶制剂可以显著提高育肥猪日增重5.58%,降低料肉比0.29(P<0.01),降低死亡率1.33%(P<0.05),降低育肥猪的单位增重成本0.62元/kg,增加经济效益35.07元/头。试验表明,在生长育肥猪日粮中添加复合酶制剂500 g/t,有利于生长猪在育肥后阶段对饲料营养物质的吸收,提高生产性能,降低生产成本,增加经济效益。

The objective of this study was to examine the effect of adding 500 g/t multi-enzyme additive in the growing-finishing pig＇s sorghum diet on production performance and economic benefit. The results showed that compared with the control group, adding multi-enzyme additive in sorghum diet could increase average daily gain significantly by 5.58%, reduce feed conversion by 0.29 （P〈0.01）, decrease mortality by 1.33%（P〈0.05）, cut the cost of weight gain by 0.62 yuan per kilogram, and increase economic benefit by 35.07 yuan per pig. Therefore, adding 500g/t multi-enzyme additive in the growing-finishing pig＇s sorghum diet benefited the absorption of nutrients, improvement of production performance, decrease of production cost and increase of economic benefit.
