摘要
通过对日本鹌鹑(Coturnix japonica)自然交配和人工授精母鸡的卵子生殖指数进行研究,评价自然交配和人工授精技术在当地鹌鹑养殖中的应用。试验选用11周龄左右的成熟鹌鹑141只(母鸡108只,公鸡33只),其中54只母鸡用15只可育公鸡的柠檬鹌鹑蛋蛋白扩展精液进行受精。另有54只母鸡由另外18只可生育的公鸡自然交配,比例为1公3母(1:3)。从自然交配和人工授精的鸟类中收集鸡蛋,孵育18天。第7天和第12天的孵卵率和第18天的出孵率测定了孵卵率。可孵化性是通过孵化出的受精卵的百分比来测试的。自然配种和人工授精的鸡蛋受精率分别为84.0%和73.3%,孵化率分别为82.5%和85.5%。研究显示,日本鹌鹑受精卵和孵化蛋的频率无显著差异(χ2 cal < χ在5%或1%概率水平上的临界值)。自然交配和人工授精的相对受精率分别为53.4%和46.6%,相对孵蛋率分别为52.5%和47.5%。人工授精的优点是,在自然交配过程中,与一只公鸡相比,它可以向更多的鹌鹑母鸡提供相同数量的精液。然而,由于技术限制,在人工授精过程中需要更多的劳动力和便利设施,因此在研究区域推荐自然交配而不是人工授精。作者建议研究开发鹌鹑约束仪器和非电性精液储存方法。作者还提出了一个鹌鹑约束模型
Reproductive Indices of Naturally Mated and Artificially Inseminated Quail Hens (Coturnix japonica): Is Artificial Insemination of Japanese Quail Hens Feasible in a Local Setting?
Naturally mated and artificially inseminated Japanese quail (Coturnix japonica) hens’ eggs reproductive indices were investigated to evaluate natural mating or artificial insemination techniques for breeding quails in local farms. A total of 141 (108 hens and 33 cocks) matured quails of about 11 weeks of age were used for the experiment, of which 54 hens were inseminated with Citric-quail egg albumen extended semen collected from 15 fertile cocks. Another 54 hens were naturally mated by another 18 fertile cocks in a ratio of one cock to three hens (1:3). Eggs collected from both naturally mated and artificially inseminated birds were incubated for 18 days. The percentage of incubated eggs that were fertile when candled on the 7th and 12th day and hatch-out analysis after the 18th day of incubation tested fertility. Hatchability was tested by the percentage number of fertile eggs that hatched. Naturally mated and artificially inseminated hens’ eggs had a fertility of 84.0 % and 73.3 %, and a hatchability of 82.5 % and 85.5 %, respectively. The study revealed no significant difference in the frequency of fertile or hatched Japanese quail eggs (χ2 cal < χ critical at 5% or 1% level of probability). Naturally mated and artificially inseminated birds had relative fertile egg rates of 53.4 % and 46.6 %, respectively, and relative egg hatching rates of 52.5% and 47.5 %, respectively. Artificial insemination had the advantage of introducing the same volume of semen to more quail hens than a single cock in a natural mating process. However, natural mating was recommended over artificial insemination in the study area because of the technical constraints that required more workforce and amenities in the insemination process. The authors recommended research on developing restraint instruments and non-electrical semen storage methods for quail birds. The authors also proposed a restraint model for quail birds
