复合发酵蚯蚓蛋白饲料对肉猪生长性能的效果试验

The effect of earthworm fermentation protein on pig growth performance

选择日龄相近,体重约30kg的大×长×金育肥猪40头,随机平均分为4组。分别为2个对照组(对照组1,2)和2个试验组(试验3,4),对照组1饲喂基础饲粮,对照组2用蝇蛆粉代替3%的豆粕。2个试验组的日粮分别用复合蚯蚓发酵蛋白替代70%和30%的豆粕,结果表明:试验3组的日增重和料肉比最好,分别为0.762kg和2.225;试验4组次之,分别为0.729kg和2.308;对照1组第三,分别为0.690kg和2.455;对照2组最慢,分别为0.683kg和2.483。虽经方差分析差异不显著,但变化趋势非常明显。经分析,试验3组经济效益最高,每千克增重成本为6.777元,平均增重收入增加1.079元,头均增加收入分别比试验4组、对照组2多30元和123.6元。

40 pigs（Y×L×J） with 30kg weight were randomly divided into 4 groups： 2 control groups（Group 1,2） and 2 experimental groups（Group3,4）. The animals were fed as： basic diet in groupl, maggot powder replaced 3% soybean meal in group2, Earthworm fermentation respectively replaced 70% and 30% soybean meal in group3,4. The results indicated that the average daily gain and feed conversion performed as following sequence： group3（0.762kg,2.225）, 4（0.729kg,2.308）,1（0.690kg, 2.455）and 2（0.683kg,2.483）. The economic benefit in Group3 was the best： weight gain cost was 6.777Yuan/kg, weight gain income increased 1.079Yuan/kg. The average income revenue in Group3 was respectively 30 Yuan and 123.6Yuan higher than in Group4 and Group2.
