中草药添加剂对生长育肥猪生产性能的影响

摘要

研究旨在针对目前中草药在三元杂交猪生长育肥研究的薄弱环节，探索中草药添加剂对生猪育肥的影响，为推广利用新型安全有效的植物性添加剂提供理论支持。选用日龄相近、60kg左右的三元杂交(杜×长×大)猪45头，随机分为A、B、C 3个组，每组15头。A组为对照组，B组、C组分别在日粮中添加0.5%和1%的中草药添加剂，研究中草药添加剂对生长育肥猪生产性能的影响。试验结果表明：B、C组的料重比、平均日耗料量显著低于A组(P＜0.05)，但平均日增重显著高于A组(P＜0.05)。研究发现，在育肥猪日粮中添加中草药添加剂可以显著提高平均日增重，降低耗料量和料重比，且以添加量为1%时效果最好。%The purpose of this research is to study the weak link for fattening growth of Chinese herbal medicine in three crossbreeding, effects of herbal medicine additive for pig fattening pigs in exploration, provides the theory support for the promotion of the use of additives plant model is safe and effective. In this study similar-aged, 60kg or so crossbred (Duroc × Landrace × Yorkshire) pigs 45, were randomly divided into A, B, C 3 groups, each group 15.A group for the control group, B group, C group were in the diets supplemented with 0.5% and 1% of the Chinese herbal medicine. The results showed that:B, C groups of the feed conversion ratio, average daily feed consumption was signiifcantly lower than the A group (P <0.05), but the average daily gain was signiifcantly higher than the A group (P<0.05). The study found that ifnishing pigs diets supplemented with Chinese herbal medicine can signiifcantly improve the average daily gain, reduced food consumption and feed conversion ratio, and to the best effect was 1%.
