小肽复合剂对育肥猪的生长性能及胴体和肉质性状的影响效应研究
|
摘要
试验旨在研究小肽复合剂对育肥猪生长性能、胴体性状及肉质性状的影响效果。将72头同批次健康的65日龄的(长×大)二元杂交商品猪随机分为试验组和对照组,每组设3个重复,每重复12头猪。试验组在正常饲粮中添加0.2%的小肽复合剂,对照组为正常饲粮。试验结果发现:育肥阶段饲喂0.2%的小肽复合剂能够显著提高育肥猪生长性能和改善肉质性状。表现为提高育肥猪的日增重(P<0.05),增加育肥猪的采食量,提高饲料转化效率,提高育肥猪群的成活率,降低生病率和腹泻率。肉质性状方面,显著降低滴水损失(P<0.05),增加了肌肉的保水力,生长性能和肉质性状的改善显著地提高了育肥猪的综合经济效益。
The purpose of this study was to inves-tigate the effects of small peptide complexes ongrowth performance, carcass traits and meat qual-ity traits in growing-finishing pigs. A total of 72 healthy 65-day-old(Landrace×Yorkshire) binarycross-commodity pigs were randomly divided in-to a test group and a control group, with 3 repli-cates in each group and 12 pigs per replicate.The experimental group added 0.2% of the small peptide complex in the normal diet, and the control group was the normal diet. The results showedthat feeding 0.2% small peptide complexes at the fattening stage could significantly promote growthperformance and improve meat quality traits.The performance was to increase the daily weight gain ofgrowing-finishing pigs(P<0.05), increase the feed intake of growing-finishing pigs, improve feed con-version efficiency, improve the survival rate of fattening pigs, and reduce the morbidity rate and diar-rhea rate. In terms of meat quality, the water retention of the muscle was significantly increased andsignificantly reduced drip loss(P<0.05). Improvement in growth performance and meat quality traitssignificantly improved the overall economic benefits of growing-finishing pig.
