| 摘 要： | 为了解决养殖污染，实现生猪清洁生产，通过在猪日粮中添加合成氨基酸、复合蛋白酶、植酸酶、寡肽等复合添加剂，最终配成低蛋白日粮，在不影响猪生长性能的同时降低猪粪便中氮、磷的含量，减轻猪场治理污染的负荷，缓解养猪对环境的压力。试验结果表明，理想的试验组中，生长猪（30～60kg）和肥育猪（60—90kg）的碍增重、料肉比、干粪中N、P含量，分别为0．74kg，2.18，1.57％，0．71％和0：81kg，3．72，2．17％，0．89％。同比对照组，日增重分别提高15.6％和31．8％，其余分别降低8．79％，25．2％，33．0％和13．3％，6．5％，15.2％。减排效果明显，并且生长性能有不同程度的提高。

| Abstract: | Study was carried out to formulate low-protein dietaries with supplementation of complex amino acid,complex enzyme,phytase and oligopeptide,with the purpose of decreasing nitrogen and phosphorous cont- ents in swine fresh feces,and relieving burdens of disposing pollution from production.Results showed that the ADG(average daily gain),F/G(feed/gain)and contents of nitrogen,phosphorus of growing pigs at 30-60 kg and finishing pigs at 60-90 kg were 0.74 kg,2.18,1.57%,0.71% and 0.87 kg,3.72,2.17%,0.89%.Compared to control group,ADG was increased by 15.6% and 31.8%,others were decreased by 8.79%,25.2%,33.0% and 13.3%,6.5%,15.2%,respectively.The effect of excretion decrease was significant,and the production perfor- mance increased with different degrees. |
