生长猪饲粮添加猪微生物添加剂与添加赖氨酸对比试验

A COMPARITIVE STUDY OF THE EFFECTS OF DIET MICROBIAL FEED ADDITIIVE AND LYSINE ON HTE PERFORMANCE OF GROWING PIGS

本试验采用饲喂试验，对“长大”断奶猪３０头与中猪３０头，分别添加猪微生物 添加剂（８７０１Ｂ）及进口赖氨酸。结果表明，适宜营养水平条件下，生长猪前期 饲粮添加８７０１Ｂ组较添加赖氨酸组提高日增重３．４个百分点；肉料比，降低２．８ 个百分点。中猪饲粮添加赖氨酸组较添加８７０１Ｂ组提高１．７个百分点，而添加 ８７０１Ｂ组的肉料比较添加赖氨酸组降低２．１个百分点．试验证明，在第一限制 性氨基酸满足需要基础上，进一步供给氨基酸的营养效果明显不如微生物添 加剂的非营养性促生长效果。饲粮营养水平适宜条件下，用芽孢菌类微生物 饲料添加剂挖掘生长猪的生产潜力是一条有效的途径。

CHang DA' pigs were used to study the effects of Microbial feed additive ' 8701B'or Lysine on performance. The trial ahiet contained an adequate nutrient. The results showed, for 18-35kg pigs with, the ahiet added '8701B', the weight gain was 3. 4%, higher and feed conversion 2. 8% lower than that of added Lysine. For 35-53kg with the chiet added Lysine, weight gain and feedconversion were 1. 7% and 2. 1% higher respectivily than that of '8701B' added. An adequate crude protein and amino acidodiet the growth-promoting response of microbial feed additive added were better than the untrition effects of the amino acid added, and it was an effective way to tab the potentianlities of pig production,with the Bucillus microbial feed additive under tie adequate nutient level.
