配种时间对母羊妊娠期生殖激素与生长激素的影响
Effect of Mating Time on Reproductive Hormone and Growth Hormone of Preganant Ewes
摘要
Abstract
To understand the changes of reproductive hormone and growth hormone of pregnant dairy goats mating in different months,ten dairy goats from central Shaanxi plain pregnant in August,October,December,and next February were randomly selected,and their venous blood was taken after mating 20 d,70 d,130 d and at delivery.Then the blood was centrifuged to take serum,the levels of Estrogen (E2),Progesterone(P4),Follicle-stimulating hormone(FSH),Luteinizing hormone(LH),Prolactin (PRL) and growth hormone (GH) in serum were measured by ELISA kit.The results showed that the changes of the same hormones of the pregnant dairy goats in different seasons were consistent during the whole pregnant period.With the extension of pregnancy,the E2,P4,PRL and GH contents of the serum gradually increased,while the FSH and LH content gradually declined;the E2,P4 content of the serum decreased,LH increased and FSH did not change significantly before delivery.The PRL and GH level of the serum gradually increased during the whole pregnancy period.The range of E2,P4,FSH,PRL and GH changes in peripheral blood were 17.45~52.90 ng/L,1899.39~6305.63 pmoL/L,4.45~6.99 IU/L,142.33~ 207.09 pg/L,367.37~626.88 ng/L,15.55~28.71 tμg/L respectively.Pregnancy in different months had little influence on their hormone levels,which indicated that dairy goats mating in different months do not have significant influence on reproductive endocrinology.关键词
