【摘要】：為了研究不同水平的消化能、蛋白質(zhì)日糧對妊娠期母兔繁殖性能和泌乳力的影響,試驗選擇健康、體況相近的經(jīng)產(chǎn)新西蘭母兔100只,隨機分為5組,每組20只,妊娠后分別飼喂標準(DE10.33 MJ/kg、CP 15.54%)、低消化能低蛋白質(zhì)(DE 9.30 MJ/kg、CP 13.44%,簡稱低能低蛋)、低消化能高蛋白質(zhì)(DE 9.40 MJ/kg、CP 18.63%,簡稱低能高蛋)、高消化能低蛋白質(zhì)(DE 11.15 MJ/kg、CP13.74%,簡稱高能低蛋)、高消化能高蛋白質(zhì)(DE 11.18 MJ/kg、CP 18.83%,簡稱高能高蛋)的日糧,分娩后測定繁殖性能相關指標。結果表明:營養(yǎng)水平對母兔血清中卵泡刺激素(FSH)、促黃體素(LH)及斷奶存活率、產(chǎn)仔數(shù)和產(chǎn)活仔數(shù)影響差異不顯著(P0.05)。低能低蛋組血清雌二醇(E2)含量顯著或極顯著高于其他試驗組(P0.05或P0.01)。高蛋白質(zhì)組母兔血清胰島素樣生長因子-Ⅰ(IGF-Ⅰ)的含量極顯著高于標準組(P0.01),標準組顯著高于低蛋白質(zhì)組(P0.05)。低能低蛋組母兔血清中催乳素(PRL)含量顯著低于其他組(P0.05),低能低蛋組母兔產(chǎn)活仔率顯著低于低能高蛋組(P0.05),斷奶存活率各組差異不顯著(P0.05)。說明妊娠期母兔蛋白質(zhì)水平對母兔和仔兔的影響比消化能水平更顯著,以高消化能高蛋白質(zhì)(DE 11.18 MJ/kg、CP 18.83%)為最佳。
[Abstract]:In order to study the effects of different levels of digestive energy and protein diet on reproductive performance and lactation of pregnant female rabbits, 100 New Zealand female rabbits with health and similar body condition were selected and randomly divided into 5 groups with 20 rabbits in each group. After pregnancy (DE10.33 MJ/kg,CP 15.54%), low digestibility and low protein (DE 9.30 MJ/kg,CP 13.44), low digestibility and high protein (DE 9.40 MJ/kg,CP 18.63), high digestibility and low protein (DE 11.15 MJ/kg,CP13.74%,), high caloric energy and high caloric energy The diet of DE 11.18 MJ/kg,CP 18.83 (high energy egg), Reproductive performance was measured after delivery. The results showed that the effect of nutritional level on serum follicle stimulating hormone (FSH),) luteinizing hormone (LH), weaning survival rate, litter size and live litter size were not significantly different (P0.05). The level of serum estradiol (E 2) in low energy egg group was significantly higher than that in other test groups (P0.05 or P0.01). The content of serum insulin-like growth factor- 鈪，
