| 摘 要： | 试验采用2×3因子设计,研究正常和T3诱导2种条件下,3个不同梯度饲粮Vc水平对肉鸡生产性能、血液生化指标、机体氧化和抗氧化功能、腹水综合征(AS)发病率及死亡率的影响。180只1日龄AA肉鸡随机分配到6个处理,每处理3重复,试验期为21 d。结果表明:①T3诱导肉鸡AS可显著或极显著降低肉鸡0~21日龄平均增重(P<0.01),血液、肝脏、肺脏总抗氧化能力(T-AOC,P<0.05);显著或极显著增加血液乳酸(Lac)浓度(P<0.01)、乳酸脱氢酶(LDH)活性(P<0.05)、心脏指数(P<0.01)、肺脏Vc含量(P<0.05),血液、肝脏和肺脏丙二醛(MDA)极显著增加(P<0.01);②饲粮Vc可极显著降低肉鸡血液Lac的浓度、LDH活性及MDA的含量(P<0.01),可显著增加肺脏T-AOC(P<0.05),降低肝脏MDA(P<0.05),1000 mg/kg Vc对肉鸡生产性能、机体抗氧化功能的改善作用比500 mg/kg Vc好;③饲料Vc对AS肉鸡的料肉比、心脏指数和血液T-AOC有显著的影响(P<0.05)。从本结果可看出,为增进0~21日龄正常和腹水肉鸡机体健康,预防肉鸡AS发生,其饲粮Vc的适宜添加量为1000 mg/kg。

| Abstract: | The trial of a 2×3 factorial arrangements with two dietary T3 level(0,1.5 mg/kg) and three Vc levels(0,500,1000 mg/kg) was conducted to investigate the effects of dietary Vc on ascites broilers from day 0 to day 21.180 Arbor Acres chicks of 1-d-old were randomly allotted into 6 treatments with three replicates per treatment and 10 birds per replicate.Water and feed were provided ad libitum for 21 days.The results showed: ① Dietary T3 could decrease significantly body weight gain(P<0.01),total antioxidative capacity(T-AOC) in the blood,lung and liver(P<0.05).Dietary T3 could increase significantly lactic acid(P<0.05),Lactate Dehydrogenase(LDH,P<0.01) and malondialdehyde(MDA,P<0.01) in the blood,increase significantly heart indexes(P<0.01) and the content of Vc(P<0.05) in the lung and hepatic MDA(P<0.01).② Dietary Vc could improve the healthy status of broilers,but the effect was related with dietary Vc supplementation.Vc in diet could decrease significantly lactic acid(P<0.05),LDH(P<0.01) and MDA(P<0.01) in the blood and hepatic MDA,and increase significantly T-AOC in lung.These results suggested dietary Vc could improve the healthy status of broilers and prevent ascites.1000 mg/kg Vc was the optimum level in diet. |
