低蛋白日粮对哺乳母猪生产性能和猪舍氨气浓度的影响

Effects of Low Protein Diet on Growth Performance and Ammonia Concentration in Lactating Sows

文章主要研究了低蛋白质日粮对哺乳母猪生产性能和猪舍氨气浓度的影响。选取胎次、体重相近的健康母猪56头,随机分成2个组,每组28个重复,每个重复1头猪。研究表明,低蛋白日粮(16%)在一定程度上能够影响哺乳母猪的生产性能,能够提高窝增重和泌乳量(P<0.05),能够降低猪舍氨气浓度,从第3周期到结束,风机位置氨气浓度下降比例分别为8.9%、9.3%、8.7%和10.9%(P<0.05),定位栏下降比例为10.9%、8.3%、5.1%和11%(P<0.05)。结果表明,低蛋白日粮能够增加母猪泌乳量,提高断奶仔猪窝增重,降低猪舍氨气浓度,减轻猪粪对环境的污染。

The effect of low protein diet on the performance of lactating sows and ammonia concentration in pig house was investigated in this paper. Selecting the similar parity and body weight 56 sows, were randomly divided into 2 groups, 28 replicates in each group and 1 pigs per replicate. The results showed that： low protein diet （16%） could af- fect the performance of lactating sows to some extent, and could increase litter weight and milk yield （P〈0.05）; could reduce ammonia concentration, from the third to the end of the cycle, the fan position of ~mmonia concentration de- creased by 8.9%, 9.3%, 8.7% and 10.9% （P〈0.05）, the drop ratio of the positioning bar was 10.9%, 8.3%, 5.1% and 11% （P〈0.05）. In conclude was that low protein diet could increase sow milk yield, increase litter weight of weaning piglets, reduce ammonia concentration in piggery, and reduce environmental pollution caused by pig manure pollution.
