摘要: 【目的】 试验旨在研究添加不同水平木薯粉对文昌鸡生产性能、血清生化及免疫指标的影响。【方法】 选取遗传背景一致、体重相近(1 215.56 g±3.73 g)的81日龄健康文昌鸡母鸡600只,随机分入5个处理组,每组设6个重复,每重复20只鸡,分别饲喂添加0(CM0组)、5%(CM5组)、10%(CM10组)、20%(CM20组)和25%(CM25组)木薯粉的饲粮。试验期40 d。试验结束后称重,计算生长性能;从每个重复选取2只鸡翅静脉采血,测定血清生化指标和免疫指标;屠宰后测定屠宰性能及脏器系数。【结果】 ①与CM0组相比,CM10、CM20和CM25组文昌鸡日增重均显著增加(P<0.05),料重比均显著降低(P<0.05)。②添加不同水平木薯粉对文昌鸡屠宰性能及脏器系数均未产生显著影响(P>0.05)。③与CM0组相比,CM20和CM25组文昌鸡血清葡萄糖水平显著提高(P<0.05);CM20组血清谷胱甘肽过氧化物酶(GSH-Px)活性显著提高(P<0.05);CM5组文昌鸡血清免疫球蛋白A(IgA)含量显著升高(P<0.05);CM25组文昌鸡血清肿瘤坏死因子-α(TNF-α)含量显著降低(P<0.05)。【结论】 添加适量木薯粉可提高文昌鸡生产性能,还能改善其糖代谢及抗氧化性能。推荐81~120日龄文昌鸡饲粮中木薯粉的适宜添加水平为20%。

Abstract: 【Objective】 This experiment was conducted to study the effects of different levels of cassava meal on production performance,serum biochemical parameters,and immune indexes of Wenchang chickens. 【Method】 A total of 600 eighty-one-day-old healthy female Wenchang chickens were randomly divided into 5 groups with 6 replicates per group and 20 chickens per replicate.Chickens were fed diets supplementing 0(CM0),5%(CM5),10%(CM10),20%(CM20),and 25%(CM25) cassava meal,respectively.The trial period lasted for 40 days.The experimental chickens were weighted on the end of the experiment and the growth performance was calculated. Two chickens’ serum in per replicates were collected for the measurement of serum biochemical indicators and serum immune indexes,and slaughter performance and organ coefficients were measured after slaughter. 【Result】 ①Compared with CM0 group,daily gain of Wenchang chickens in CM10,CM20 and CM25 groups was significantly increased (P<0.05),while the ratio of feed to gain were significantly decreased (P<0.05).②Supplementing different levels of cassava meal had no significant effects on slaughtering performance and organ coefficients of Wenchang chickens (P>0.05).③Compared with CM0 group,serum glucose levels of Wenchang chickens in CM20 and CM25 groups were significantly increased (P<0.05);Serum glutathione peroxidase content of Wenchang chickens in CM20 group was markedly increased in comparison to CM0 group (P<0.05). Compared with CM0 group,the serum immunoglobulin A content of Wenchang chickens in CM5 group was significantly increased (P<0.05),but serum tumor necrosis factor-α content of CM25 group was significantly decreased (P<0.05). 【Conclusion】 Supplementing appropriate amount of cassava meal could improve production performance of Wenchang chickens,and improve the glyco metabolism as well as antioxidant properties.Therefore,it was recommended that the appropriate level of cassava meal in the diets of Wenchang chickens aged from 81 to 120 days was 20%.
