| 摘 要： | 选取设计6个处理组,每组6个水平,每个水平6只蛋鸭。分别添加VC 0、200、800 mg.kg-1,温度(2±1)℃或(18±1)℃,试验期为6、12周龄金定蛋鸭216只,设两个温度水平,研究了环境温度和VC(维生素C)对后备蛋鸭免疫器官发育及抗氧化的影响。结果表明,低温对胸腺指数影响显著(P0.05),VC对脾脏指数和法氏囊指数影响不显著(P0.05),但随着VC添加量的提高,脾脏指数和法氏囊指数有上升趋势。低温和维生素C的交互作用对胸腺指数影响显著(P0.05)。低温和维生素C对血清一氧化氮(NO)、维生素C影响显著(P0.05),对GSH-PX的影响不显著(P0.05)。由此可知,寒冷应激影响后备蛋鸭体内VC的合成,但日粮中添加VC 200 mg.kg-1时,可提高血液VC的水平,对低温应激组胸腺、脾脏和法氏囊的萎缩有缓解的趋势。

| Abstract: | The experiment was conducted to study the effects of the ambient temperature and Vitamin C on immune organ development and anti-oxidative capability of reserve ducks.A total of 216 reserved laying ducks(JIN Ding duck,12 weeks old) were randomly divided into 6 treatments and each treatment contained 6 replicates with 6 ducks per replication.The trial lasted for 6 weeks.The basal diet supplemented 0,200 and 800 mg·kg-1 Vitamin C(VC),respectively.The ambient temperatures were(2±1) ℃ or(18±1) ℃,respectively.The results showed as follows: low temperature had a significant effect on thymus index(P<0.05);VC had nosignificant effect on spleen index and the bursa of index(P>0.05);the spleen index and the bursa of index showed escalating trend as the increasing of VC.The interaction of the low temperature and VC had a significant effect on thymus index(P<0.05).Ambient temperature significantly affected the concen-tration of serum nitric oxide(NO) and VC(P<0.05).In conclusion,the cold stress affected the synthesis of VC in vivo of reserved laying ducks.However,when diets supplemented with VC 200 mg·kg-1 increased the contents of serum VC and mitigated the trend of atrophy of thymus,spleen and bursa in the cold stress. |
