饮水添加沼液对肉鸡生产性能的影响

沼气池的建设是农村新能源综合开发利用推广项目之一,极大地提高了农民生活质量。沼液、沼渣的再开发利用是进一步推进该项目所面临的问题。饮水中添加50%的沼液饲喂4周龄AA肉仔鸡进行35d生长试验,效果明显。平均每只鸡增重0.0666±0.0166Kg,比对照组提高7.5%,总耗料量降低2.7%,料重比降低0.34,均差异显著(P<0.05)说明饲料转化率明显提高。成活率试验组比对照组提高2个百分点。屠宰率提高0.85个百分点,差异不显著(P>0.05),但胸肌率比对照组提高4个百分点,差异显著(P<0.05)。

Effect of Adding Biogas Slurry in Drinking Water on Production Performance in chicken

The construction of biogas pond is a new energy development and promotion project in countryside.Development of Biongas slurry and Biogas residue is very important in countryside.The AA chicken aged 4 weeks were fed with drinking water with adding 50% of Biogas slurry for 35d growth.The result showed that body weight of each chicken on verage increases 0.066±0.0166kg,7.5% higher than controling group.Total consumption feed decrease by 2.7%.The ratio of feed and body weight decrease 0.34.There is a significant difference between them.(P<0.05).The feed conversion rate increased significantly.The survial rate increased by 2%.the slaughter rate increased by 0.85%.There is no significant difference between then(P>0.05),but rate of chest muscle increased by 4% than control group.There is a significant difference between them(P<0.05).
