中文摘要：高温引起的鸡热应激会导致其生殖机能严重下降。本试验以26周龄雌性怀乡鸡为研究对象,探究斑蝥黄对循环高温环境中怀乡鸡产蛋性能、生殖激素水平、卵泡发育的影响。结果表明,与常温对照相比,循环高温环境中怀乡鸡产蛋率及血清中促卵泡素(FSH)、黄体生成素(LH)、孕酮(P_(4))、雌二醇(E_(2))水平降低,等级卵泡、小黄卵泡、大黄卵泡、小白卵泡、大白卵泡数量降低,卵泡膜结构松散、断裂,卵泡颗粒细胞结构受损。常温环境中,饲粮中添加斑蝥黄对怀乡鸡产蛋性能、血清中生殖激素水平有一定提升作用,但对卵泡膜结构无明显影响。循环高温环境中,饲粮中添加斑蝥黄能够显著改善怀乡鸡产蛋性能,提高血清中生殖激素水平,提高各级卵泡数量,缓解高温造成的卵泡膜松散、断裂和卵泡颗粒细胞损伤。综上,斑蝥黄具有较强的抗氧化特性,能够提高怀乡鸡产蛋性能,调节血清中生殖激素水平,降低高温对怀乡鸡造成的伤害,使各级卵泡正常发育并排出。

外文摘要：Heat stress of chicken caused by high temperature can lead to the seriously decline of reproductive function.Effects of canthaxanthin on laying performance,reproductive hormone level and follicle development of 26-week-old female Huaixiang chickens in cyclic high temperature environment were studied.The results showed that,compared with control group of room temperature,the laying rate,levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),progesterone(P 4)and estradiol(E 2)in serum decreased in Huaixiang chickens exposed to circulating high temperature,and the number of grade follicles,small yellow follicles,large yellow follicles,small white follicles and large white follicles decreased.The structure of follicular membrane was loose and broken,and the structure of granulosa cells of follicles was damaged.In normal temperature environment,diet added with canthaxanthin could improve laying performance and serum reproductive hormone level of Huaixiang chickens,but had no obvious effect on follicular membrane structure.Adding canthaxanthin into the diet could significantly improve laying performance,serum reproductive hormone levels and follicle number of Huaixiang chickens in cyclic high temperature to alleviate the looseness,rupture of follicular membrane and damage of follicular granulosa cells caused by high temperature.In conclusion,canthaxanthin has strong antioxidant properties,which can improve laying performance,regulate the level of reproductive hormones in serum of Huaixiang chickens,and can reduce the harm caused by high temperature to make all levels of follicles develop and ovulate normally.
