饲养实践证明.提高亲鳖受精率是获取养鳖高效益的重要环节.但一些鳖场的亲鳖产蛋不少,受精率却很低。从而严重地影响了养鳖效益.要提高亲鳖受精率.关键是把好以下三项技术.(1)选择优良雄鳖选择优质健壮的雄亲鳖是提高亲鳖繁殖受精率的关键.要挑选体重在1.5~3公斤、年龄在4~8周年的体形标准。无伤无病的雄亲鳖.用于繁殖的亲鳖群体中。不可掺养未成熟的后备亲鳖.雌雄配比以1∶3为宜.(2)创造最佳环境试验表明.优良的生态环境也是提高亲鳖受精的重要因素。亲鳖的交配在晴天月明
Feeding practice proves that to improve the fertilization rate of soft-shelled turtle is to gain an important part of raising turtle high efficiency, but some soft-shelled Turtle baby laying eggs, but the fertilization rate is very low. Thus seriously affecting the benefits of raising turtles .To improve the fertilization rate of the progeny, the key is to take the following three techniques. (1) Selection of excellent turtles to choose high quality and robust male turtle is to improve the fertilization rate of soft-shelled turtle key. Select the body weight of 1.5 to 3 kg, aged 4 to 8 years of body shape standards. Injured disease-free male turtle. For the breeding of soft-shelled turtle population. Can not be mixed with immature reserve of soft-shelled turtle, male and female ratio of 1: 3 is appropriate. (2) to create the best environmental tests show that good ecological environment is also an important factor to improve fertilization of pro-turtle. Pro-turtle mating on a sunny day
