复合酸化剂对白羽肉鸡生长性能及血液生化指标的影响
|
摘要
试验旨在研究复合酸化剂对白羽肉鸡生长性能与血液生化指标的影响。选用健康1日龄白羽肉鸡600只(公苗),按体重一致原则随机分为四个组,分别为对照组(饲喂基础日粮)、抗生素组(在基础日粮中添加含量15%的金霉素0.5 g/kg)、酸化剂A组(在基础日粮中添加乳酸型复合酸化剂2 g/kg)、酸化剂B组(在基础日粮中添加甲酸型复合酸化剂2 g/kg)。结果显示:1～16日龄阶段,与对照组相比,抗生素组、酸化剂B组肉鸡的日均增重显著增加(P<0.05);抗生素组、酸化剂A组、酸化剂B组肉鸡的料重比显著降低(P<0.05)。与对照组相比,抗生素组、酸化剂B组肉鸡血清尿酸浓度显著降低(P<0.05);抗生素组、酸化剂A组、酸化剂B组肉鸡血清碱性磷酸酶活性显著增加(P<0.05);酸化剂A组、酸化剂B组肉鸡血清T-AOC活性显著高于对照组、抗生素组(P<0.05);抗生素组肉鸡血清丙二醛含量显著高于对照组、酸化剂A组、酸化剂B组(P<0.05)。结果表明:两种复合酸化剂对肉鸡前期生长性能有促进作用,对后期促生长作用效果不明显。复合酸化剂可以降低肉鸡血清尿酸的浓度,提高抗氧化能力,降低MDA含量。
Total of 600 one-day-old healthy white-feather broilers were randomized into 4 groups by the weight consistency principle,including the control group(fed with basal diet),antibiotics group(supplemented of 15% aureomycin0.5 g/kg in basal diet),acidifier A group(supplemented of 2 g/kg of lactic acid compound acidifier in basal diet) and acidifier B group(supplemented of 2 g/kg of formic acid compound acidifier in basal diet).The results showed that,in the growth performance,supplementation of aureomycin and acidifier B in basil diet significantly increased the daily weight gain(DWG)(P<0.05),supplementation of aureomycin,acidifier A and acidifier B significantly decreased the ratio of daily feed intake to DWG(P<0.05),comparing with control group during 1 to 16 days of age.Supplementation of aureomycin and acidifier B significantly decreased the uric acid concentration(P<0.05),supplementation of aureomycin,acidifier A and acidifier B significantly increased,the AKP activities comparing with control group(P<0.05).The T-AOC activities of acidifier A and acidifier B groups were significantly higher than those of control group and antibiotics group(P<0.05).The content of malondialdehyde of antibiotics group was significantly higher than those of control group,acidifier A and acidifier B groups(P<0.05).The results indicated that the compound acidifier had a positive effect on the growth performance of broilers at the early stage,but had no significant effects at the later stage.Furthermore,compound acidifier could improve some serum biochemical indexes of broilers.
