纳米氧化锌对肉仔鸡血清生化指标的影响

Effects of Nanometer Zinc Oxide on the Biochemical Index of Broilers

本试验旨在研究纳米氧化锌对肉仔鸡生化指标的影响。选取1日龄艾维茵肉仔鸡,随机分为4个处理,处理1为对照组,在基础日粮中添加80mg/kg氧化锌,处理2、3、4组分别添加40、80、200mg/kg钠米氧化锌。分别于14和28日龄每个处理组随机取6只鸡测血清生化指标。试验结果表明:与对照组相比,各试验组28日龄血清锌含量都表现出提高的趋势,其中处理4达到显著水平(P<0.05);处理3和处理4显著提高28日龄血清谷草转氨酶(P<0.05)活性,处理2也表现出明显的提高趋势;在14日龄各试验组血清总蛋白含量均表现出提高的趋势,其中处理2达到显著水平(P<0.05),血清球蛋白和白蛋白也表现出提高的趋势。但在28日龄处理3却显著降低血清白蛋白含量(P<0.05),处理2和处理4也表现出降低的趋势;处理3和处理4显著提高了14日龄血清胆固醇含量(P<0.05),处理2也表现出提高趋势,但28日龄各处理却表现出降低的趋势,其中处理2达到显著水平(P<0.05)。因此,在本试验条件下,添加40mg/kg钠米氧化锌对肉仔鸡血清锌、GLU、AKP、AST和ALT活性未产生影响;添加200mg/kg钠米氧化锌可以提高肉仔鸡血清锌含量;添加80和200mg/kg钠米氧化锌影响肉仔鸡血清谷草转氨酶活性和胆固醇含量。

Effects of nanometer zinc oxide on the biochemical index of broiler were studied. One day old Avian broilers were divided into 4 groups. Group 1 was control group, added 80 mg/kg ZnO in the basal diet, group 2,3 and 4 were added 40,80 and 200 mg/kg nanometer zinc oxide respectively. Serum were got from 6 chicken to determine biochemical index on 14 day and 28 day. The results showed that, compared with control group, serum Zn content increased on 28 day in group 2,3 （P〉 0.05）and 4（P〈0.05）. AST was increased in group 3 and 4 significantly（P〈0. 05）and in group 2 （P〉0. 05）on 28 d. Serum TP increased in group 3, 4（P〉0.05）and significantly in group 2（P〈0.05） on 14 d, Serum GLO and ALB increased too （P〉0.05）. ALB decreased significantly in group 3 （P〈0. 05）and in group 2, group 4（P〉0. 05）on 28 d. CHOL increased in group 3 and group 4（P〈0.05）and group 2（P〉0.05）on 14 d,but decreased in group 3（P〈0.05）and group 2,group 4（P〉 0.05） on 28 d. In conclusion, serum Zn, GLU,AKP,AST, ALT were not influenced by adding 40 mg/kg nanometer zinc, serum Zn was improved by adding 200 mg/kg nanometer zinc, serum AST and CHOL were influenced by adding 80,200 mg/kg nanometer zinc oxide.
