中文摘要 | 二十二頭初產、十二頭經產荷蘭母牛(產後15~20天)逢機分配至對照組(G組)與三 個處理組 (CG 組, PG 組與 CPG 組 ) 分析給予合成助孕素 (CIDR) 與妊馬血清激性腺素 (PMSG) 等外源內泌素對產後重建卵巢功能的影響。 各組牛隻之處理情形如下: (1)G 組 - 對照性質,僅做 GnRH 處理; (2)CG 組 - 於試驗開始時 (第 0 天 ) 由陰道置入 CIDR,9 天後取出; (3)PG 組 - 在試驗進行至 8.5 天時由皮下注入 1,000IU PMSG; (4)CPG 組 - 同時接受 CIDR 與 PMSG 兩種處理。此外,所有牛隻均在試驗開始後第 11 天注射 (im)100 ug 激性腺素釋放素 (GnRH) 並自頸靜脈以 15 分鐘間隔連續抽血 6 個小時,隨後以隔天方 式抽血 20 天。牛隻自試驗開使後觀察發情,而於生產 45 天後偵得發情時進行人工授精。 各組牛隻在第 9 天 (相當於 CIDR 移走時間 ) 以後的發情比例並無區別,受胎率則以 CPG 組 (第一次配種: 78%) 最高,若依助孕素濃度來判定, 三個處理組的發情比例均顯著高於 對照組 (P<0.05), 而 CG 組 (10.8 天 ) 與 PG 組 (11.7 天 ) 自試驗開始至產後第一 次發情所需時間則較 G 組 (15.2 天 ) 為短 (p<0.05)。排卵素 (LH) 的平均濃度與排卵前 高峰值, 三個處理組間並無差異,但均顯著高於對照組 (p<0.05)。 CIDR 的單獨處理 (CG 組 ) 有增進排卵 (100%) 與延長黃體期 (18.6 ± 1.8 天 ) 的作用 (P< 0.05),其他兩組 亦有改善趨勢,唯作用較不明顯; 孕酮 (P �� ) 分泌量 CPG 組顯著高過 G 組 (69 ± 14 vs 23 ± 13 ng,P<0.05),但與其他兩組無異。 以上結果顯示,合成助孕素可能具有調節 下視丘 - 腦下腺 - 卵巢軸的作用,進而對乳牛產後卵巢功能的恢復與生殖效率的提升有所 助益。 |
英文摘要 | Twenty two primarous and twelve multiparous Holstein cows (15 to 20 days postpartum)were randomly assigned to control (GnRH;G) and three treatment groups (CG, PG and CPG) to investigate the influence of given exogenous hormone CIDR and PMSG on the reestablishment of postpartum ovarian function. Each cow received one of the following treatments:(1) G group- no treatment, served as control;(2) CG group -from the beginning of experiment (day 0), inserted CIDR for 9 days: (3) PG group - PMSG (1,000IU) in a single subcutaneous injection at 8.5 days;(4) CPG group- receive both CIDR and PMSG treatment. Then all cows wer administered 100 ug GnRH (im) at day 11. After GnRH, blood sample were collected at 15 min interval for 6 hours and then every other day for the next 20 days. Cows were then observed for estrus at the beginning of the experiment and were artifically inseminated at the first observed estrus after 45 days postpartum. There were no difference in the percentage of cows exhibiting estrus after CIDR was removed. The first service conception rate was highest in CPG group. The interval between the start of the experiment and the time of first observed estrus, if judged by serum progesterone concentration, CG group (10.8 d) and PG group (11.7 d) were significantly (P<0.05) shorter than G group (15.2 d). The average serum LH concentration and the preovulatory peak magnitude of LH value showed no difference among three treatment groups, but were greater (P<0.05) in treated group. While using CIDR (CG group) as sole treatment has successfully induced ovulation (100%) and extent the length of luteal phase (18.6 ± 1.8 d), it also had certain extent of improvement in PG and CPG groups, but the difference was not significant. Progesterone concentration was greater in CPG group than G group (69 ± 14 vs 23 ± 13 ng,P<0.05), but showed no difference from other two groups. The above data indicated that progesterone treatment might have positive effect on the regulation of hypothalamic- pituitary-ovarian axis which might be beneficial to the improvement of postpartum ovarian function and the reproductive efficiency in dairy cows. |
