| 摘 要： | 为从“源头控制”畜禽粪便减排,提高生猪养殖效益,本试验将同日龄、初始体重相近的（P>0.05）育肥猪40头分成4个组,1个对照组（正常饲喂）和3个试验组,每组10头,试验组分限饲10%组、限饲20%组、限饲30%组。试验组限饲50 d后,解除限制饲喂30 d,在管理条件基本相同情况下发现限饲期间,试验各组猪的粪便产生量、末重和平均日增重均显著低于对照组（P<0.05）;解除限饲后,与对照组相比,限饲20%组和限饲30%组猪的粪便排放量显著降低,平均日增重显著增高（P<0.05）,而限饲20%组猪的试验末重略高于对照组且差异不显著,限饲30%组则显著低于对照组。结果表明限饲20%组的猪粪便排泄量减少,补偿生长方式相对效果较好。

| Abstract: | In order to control the emission reduction of livestock manure from the source and improve the benefit of pig breeding, 40 finishing pigs of the same age and similar initial weight (P>0.05) were divided into 4 groups, 1 control group (normal feeding) and 3 experimental groups, each group had 10 pigs. The experimental group was divided into feeding restriction 10% group, feeding restriction 20% group and feeding restriction 30% group. After 50 days of feeding restriction and 30 days of lifting feeding restriction, the feeding and management conditions of each group were basically the same, the results showed that during the feeding restriction period, the fecal production, final weight and average daily gain of each group were significantly lower than those of the control group (P<0.05); After the lifting of feed restriction, compared with the control group, the feces of the feed restriction 20% group and feed restriction 30% group were significantly decreased, and the average daily gain was significantly increased (P<0.05), while the final weight of the 20% feed restriction group was slightly higher than that of the control group, and the difference was not significant, and the 30% feed restriction group was significantly lower than that of the control group. Comprehensive analysis showed that the fecal excretion of 20% feed restriction group was reduced, and the effect of compensatory growth mode was better. |
