日粮中添加牛至油对生长育肥猪生产性能的影响

为牛至油在生长育肥猪养殖上的应用提供参考,选择体况健康、初始体重差异不显著的长大二元杂交生长育肥猪198头,按体重接近的原则随机分为3个处理,试验1组(饲喂普通312料,CK)、试验2组(在普通312料中添加500mg/kg牛至油)和试验3组(在普通312料中添加200mg/kg牛至油),每个处理3个重复,每个重复22头猪,研究牛至油对生长育肥猪生产性能的影响。结果表明:与CK相比,日粮中添加牛至油500mg/kg可降低猪的腹泻率、发病率和死淘率,分别降低0.6百分点、0.59百分点和1.45百分点;同时可增加猪的日采食量、促进生长,其日增重达762.48g/头,料肉比为2.37。日粮中添加牛至油200mg/kg对猪只健康状况有一定程度的改善作用,但生产性能表现不佳。

Effect of Adding Oregano Oil in the Daily Ration on Growth Performance of Growing-finishing Pigs

198 healthy two-way crossbred growing-finishing pigs with no obvious different initial weight were randomly divided into three test groups with three repetitions (22 pigs / repetition).Group Ⅰ,Group Ⅱ and Group Ⅲ were fed with "312" daily ration,"312" daily ration + 500 mg/kg oregano oil and "312" daily ration +-200 mg/kg oregano oil respectively to study the effect of oregano oil on growth performance of growing-finishing pigs and provide a reference for application of oregano oil in breeding of growing-finishing pigs.Results:The diarrhea rate,morbidity and death rate of growing finishing pigs fed with "312" daily ration + 500 mg/kg oregano oil decrease by 0.6％,0.59％ and 1.45％ respectively compared with CK and the daily gain and feed conversion ratio are 762.48 g/pig and 2.37 separately because feeding oregano oil can increases average daily feed intake and promote pig's growth.The "312" daily ration + 200 mg/kg oregano oil treatment is of the improvement effect to a certain extent on pig's health status but its growth performance is not good.
