摘要
本试验旨在研究4种复合添加剂对乌骨鸡产蛋性能和血液生化指标的影响。选取300日龄乌骨鸡180只,随机分成5组,在1～4组的基础日粮中分别加入0.5%、0.2%、0.2%和0.2%的4种复合添加剂,第5组饲喂基础日粮。试验期为78 d。结果表明,添加复合添加剂可以提高乌骨鸡产蛋率,第1、2、4组产蛋率分别比对照组高6.09%、13.82%和6.57%(P<0.05);第2组的平均蛋重和料蛋比最低,分别比对照组低2.05%和12.5%(P<0.05)。第1组的总胆固醇含量和葡萄糖浓度分别比对照组低21.24%和8.93%(P<0.05),肌酸激酶浓度比对照组高32.73%(P<0.05);第2组的血液生化指标与对照组之间均差异不显著(P>0.05);第3组试验鸡的血清丙二醛和肌酸激酶浓度显著高于对照组(P<0.05);第4组的葡萄糖浓度比对照组高13.97%(P<0.05),总胆固醇含量比对照组低13.72%(P<0.05)。
The aim of this experiment was to study the effects of 4 kinds of compound additives on performance and serum biochemical index in Black-bone silky fowl.One hundred and eighty chickens at the age of three hundred days were selected and randomly allocated to five treatment groups with three replicates,four diets containings four different compound additives（0.5%,0.2%,0.2% and 0.2%） and basic diet were given to feed these chickens for 78 days in order to.The results showed that laying rates were increased with diets of compound additives.When compared to control group,the laying rates of group 1,2 and 4 were significantly increased by 6.09%,13.82% and 6.57%（P0.05）,respectively.The values of average egg weight and the feed conversation rate of group 2 were the least in these treatment groups and were decreased by 2.05% and 12.5% compared to control group（P0.05）.The content of total cholesterol（TC） and glucose（GLU） of group 1 were decreased by 21.24% and 8.93%（P0.05）,and the content of creatine kinase（CK） was increased by 32.73%（P0.05） compared to control group.There were no difference between group 2 and control group at all the serum biochemical index.The concentration of malonaldehyde（MDA） and CK of group 3 were lower than that of control group（P0.05）.The content of GLU of group 4 was increased by 13.97%（P0.05） and the content of TC was decreased by 13.72%（P0.05） compared to control group.
