Abstract

This study was carried out to determine the impact of the mode of reproduction and the strain (male and female) of rabbits on some zootechnical and reproduction parameters. For that, monitoring was carried out in 2019 in the region of Setif (North Eastern Algeria) on a semi-intensive breeding of 25 crossbreed rabbits. The statistical analysis showed a very highly significant effect of the mode of reproduction on the number of mating per fertilizing mating (P= 0.0001) with an average of 1 ± 0 in AI (Fertility rate of 80%), while it was of 1.45 ± 0.51 in natural breeding with a fertility rate of 61%. The weight of the rabbits at weaning was higher in AI than in natural mating (587.25 ± 338.19 g vs. 575.0 ± 375.44 g, respectively). The results relating to the number of total born, born alive, weaned rabbits, the farrowing-mating interval and the farrowing-fertilizing mating interval in natural mode were respectively of (7.4 ± 3.12), (4.55 ± 3.12), (4.55 ± 3.12), (12.65 ± 2.30), (19.15 ± 3.58); and in AI: (6.90 ± 4.12), (5.75 ± 4 .12), (5.75 ± 4.12), (11.65 ± 2.05), (18.99 ± 3.2) (P>0.05). Furthermore, and regarding the strains, data revealed that the females did not have any significant effect on the variables studied. On the contrary, the male had a very highly significant effect on the number of mating per fertilizing mating (p = 0.000), while it had no impact on the other parameters (P>0.05). To conclude, the control and the management of reproduction is the key to success in rabbit breeding, thus the combination of rearing condition and genetic effects is the main tool for making rabbit farming successful.

繁殖模式和品系对家兔繁殖性能的影响

本研究旨在确定兔子的繁殖模式和品系（公兔和母兔）对一些动物技术和繁殖参数的影响。为此，2019 年在塞提夫地区（阿尔及利亚东北部）对 25 只杂交兔的半密集繁殖进行了监测。统计分析显示，繁殖方式对每次受精交配次数的影响非常显著（P= 0.0001），人工授精平均为 1 ± 0（受精率为 80%），而自然繁殖为 1.45 ± 0.51（受精率为 61%）。人工授精兔断奶时的体重高于自然交配兔（分别为 587.25 ± 338.19 g 对 575.0 ± 375.44 g）。自然交配模式下的总出生兔数、活产兔数、断奶兔数、产仔-交配间隔时间和产仔-受精-交配间隔时间分别为（7.4±3.12）、（4.55±3.12）、（4.55±3.12）、（12.65±2.30）、（19.15±3.58）；人工授精：（6.90±4.12）、（5.75±4 .12）、（5.75±4.12）、（11.65±2.05）、（18.99±3.2）（P>0.05）。此外，关于菌株，数据显示雌性对所研究的变量没有任何显著影响。相反，雄性对每次受精交配的次数有非常显著的影响（P = 0.000），而对其他参数没有影响（P>0.05）。总之，繁殖的控制和管理是养兔成功的关键，因此，饲养条件和遗传效应的结合是养兔成功的主要工具。
