摘要
文章旨在探讨复合酶制剂对芦花鸡生长性能、屠宰性能及血液生化指标的影响。试验将600羽体重相近的42日龄脱温芦花鸡随机分为对照组、复合酶1组和复合酶2组,每组5个重复,每个重复40羽芦花鸡,试验为期78d。结果显示,与对照组相比,芦花鸡42、84和120日龄体重,以及42~120日龄、85~120日龄的ADG、ADFI和F/G均无显著差异(P> 0.05),42~84日龄,复合酶2组的ADG显著高于对照组(P <0.05);复合酶组能提高血液TP、ALB、BUN含量和SOD活性,降低GLU和MDA含量,复合酶2组的TG和TC含量均显著高于对照组(P <0.05),复合酶1组和2组的UA含量分别显著(P <0.05)、极显著(P <0.01)低于对照组;复合酶组屠宰率、全净膛率和半净膛率均有所提高,复合酶组胸肌率和复合酶2组腿肌率均显著高于对照组(P <0.05)。综上所述,重庆山地饲养芦花鸡日粮中添加复合酶制剂可促进芦花鸡生长和蛋白合成,优化脂类代谢,提高鸡体抗氧化能力,提高屠宰性能。
This experiment was conducted to investigate the effects of compound enzyme preparation on the growth performance,slaughter performance,and blood biochemical indicators of Luhua chickens.A total of 600 Luhua chickens were divided into control group and two enzyme groups which contained 5 replicates in each group and 40 pigs in each replicate.The experimental period was 78 d.The results showed that there were no significant differences of body weight at 42,84,120 days old,the same as ADG、ADFI、F/G in periods of 42 ~ 120-day and 85 ~ 120-day.The ADG of 42 ~ 84-day period was significantly higher than the control group(P < 0.05).The content of TP,ALB,BUN,and SOD were improved,the GLU and MDA were reduced.The content of TG and TC in enzyme group 2 were significantly higher than the control group(P < 0.05).The content of UA in enzyme group 1 and group 2 were significantly(P < 0.05)and extremely significant(P < 0.01)lower than the control group respectively.The slaughter rate,full bore rate,and half bore rate were all improved.The chest muscle rate and the leg muscle rate of enzyme group 2 were significantly higher than the control group(P < 0.05).In summary,it can promote the growth,protein synthesis,lipid metabolism,antioxidant-ability,and slaughter performance by adding complex enzyme preparations to diet of Luhua chickens.
