Abstract

In two separate artificial insemination trials with individually caged breeder turkeys, semen release in the oviduct at depths of 3.0 and 7.5 cm from the exterior surface of the relaxed vent were compared. In the first trial, 7.5 cm. insemination at two-week intervals produced significantly higher (82.3 vs 78.5%) fertility and lower embryonic mortality (16.8 vs 20.2%) than the 3.0 cm. depth. In the second trial, insemination at three-week intervals, 7.5 cm. depth also produced significantly higher (79.2 vs 73.9%) fertility and lower embryonic mortality 11.2 vs 15.6%). The net gain in reproduction efficiency due to the combined effects was 6% in Trial 1 and 8% in Trial 2.

摘要

在两项分别针对单独饲养在笼中的种火鸡的人工授精试验中，比较了从松弛泄殖腔外表面起3.0厘米和7.5厘米深度处输卵管内精液释放情况。在第一项试验中，每隔两周进行7.5厘米深度的输精，其受精率显著高于3.0厘米深度的输精（82.3%对78.5%），胚胎死亡率则更低（16.8%对20.2%）。在第二项试验中，每隔三周进行输精，7.5厘米深度的输精同样产生了显著更高的受精率（79.2%对73.9%）和更低的胚胎死亡率（11.2%对15.6%）。由于综合效应，第一项试验中繁殖效率的净增益为6%，第二项试验中为8%。
