中文摘要 | 本試驗之主要目的為應用外源性內泌素處理,提早誘發產後母山羊同期發情與配 種,以克服產後乏情之困難,進而縮短母山羊之胎距,提高其繁殖效率。採用努比亞與本地 山羊之雜種母羊合計 79 頭, 於產後第 18 日開始以助孕素釋放器 (CIDR) 留置於陰道內 11 日, 惟於取出 CIDR 前 48 小時, 每頭母山羊肌肉注射 500 IU 孕馬血清激性腺素 (PMSG) 及 125 μ g 合成前列腺素 cloprostenol,並以 69 頭未予任何處理之母山羊為對 照,以瞭解其對產後發情、排卵及懷孕等繁殖性狀之影響。試驗結果顯示,處理組母山羊於 產後 60 天內之發情與懷孕率分別為 92.4% 與 56.9%, 均顯著高於對照組之 46.4% 與 36.2% (P<0.01)。雖然處理之效果在春、秋兩季分娩之母山羊群間無顯著差異,惟秋季分娩 之母山羊於處理後,懷孕率有提高之趨勢。 在連續 4 ~ 5 個配種季節中,接受內泌素處理 之母山羊,平均每年產羔數仍較對照組為高 (1.40 vs 1.25)。 此外,母山羊之產羔率亦以 處理組較高 (192 vs 159) (P<0.05)。由以上結果顯示,利用內泌素處理產後第 18 日之母 山羊,確能增加其產後 60 日內配種之機會,而提高山羊群之繁殖效率。 |
英文摘要 | This study was conducted to examine the effects of hormone treatments on the improvement of reproductive efficiency in meat goat herd. A total of seventy-nine postpartum Nubian-Native crossbred does were treated in kidding/breeding seasons twice annually for 3 consecutive years. CIDRs were placed in vaginae of does on day 18 postpartum for 11 days. Each doe was administered with 500 IU of PMSG and 125 μ g of cloprostenol at 48 hours prior to CIDR withdrawal. The percentage of does showing behavioral estrus within 60 days postpartum and the conception rate of hormone-treated does were 92.4% and 46.4% respectively, which were significantly higher (P<0.01) than the control does, irrespective of the seasons. The average kidding rate and annual kids dropped in hormone treated groups were higher than the control group (192 and 1.4 vs 159 and 1.25). These results indicated that fertile estrus of does could be induced and synchronized within 60 days postpartum, which could improve the reporductive efficiency of doe. |
