摘要/Abstract

摘要： 本试验以42 d繁殖模式为基础,在人工授精前48 h分别给母兔注射不同剂量(0、10、20、30和40 μg)的氯前列烯醇(cloprostenol,CLO)以进行同期发情,并进行产仔率、产仔总数、产活仔数、活窝重、仔兔个体重及雌激素、孕激素等指标检测。结果显示,与对照组相比,注射不同剂量CLO的母兔产仔率都有极显著的提高(P<0.01),且产仔率随注射剂量的增加呈递增趋势;但各组中母兔产仔总数无显著变化(P>0.05)。激素测定结果显示,注射CLO后雌激素水平逐渐上升,且上升的幅度随剂量的增加而加大;注射10、20和40 μg CLO 24和48 h后,孕激素浓度显著降低(P<0.05)。因此,采用氯前列烯醇对母兔进行同期发情,可有效促进母兔的发情,进而提高母兔产仔率和生产效率。

Abstract: The conduct was on the basis of 42 d propagation mode, 48 h before artificial insemination, mother rabbit were injected of different doses of cloprostenol (CLO) (0, 10, 20, 30 and 40 μg) for the same period, and total farrowing rate, litter size at birth, number born alive, litter weight at birth, mean kit weight at birth and estrogen and progesterone were recorded.Results showed that, compared with control group, the injection of different doses of the CLO to mother rabbit, the farrowing rate was very significantly improved (P<0.01), and showed increasing trend with the increasement of the dose;But between groups,the litter size at birth had no significant change (P>0.05).Results about hormone showed that after injection of CLO,the level of estrogen was increased. Progesterone concentrations significantly decreased after injection of CLO (P<0.05), respectively in 24 h and 48 h after injection of two time points,10,20 and 40 μg groups were significantly lower than 0 μg group. Therefore, using the high chlorine enol promote the mother rabbit estrus and then mother rabbit farrowing rate and production efficiency could be improved.
