查询词典 hatchability

In chronic exposure, significant changes in length, weight and cumulative mortality rate of fish was observed at concentrations higher than 0.4mg·L-1, but no effect on hatchability.

慢性暴露中，对孵化时间影响的最低可观察效应浓度（LOEC30d）为0.1mg·L-1；暴露于0.4mg·L-1的高锰酸钾对30d后日本青鳉的体长、体重、累计死亡率均有显著影响，但对孵化率率无显著影响。

The body length has great individual diversity normally ranged from 25-60 cm, It also shows strong phototaxy. One lamp can trap more than 2 000 of them per night. Female imago has a large egg load with the maximum amount of 543. The eggs hatching is in depth of 1-3 cm soil. The dominant hatching period of egg is from late June to early July, and hatchability is over 85%. The living space of larva ranges from 15-60 cm in soil.

Experiments were conducted with fertile chicken eggs to determine the effects ofthyroxine and thiouracil on chicken digestive enzyme activity,hatchability and yolk-absorption.

分别测定孵化第17d、第19d及1、5、10、15、20日龄小鸡的腺胃、十二指肠与胰腺匀浆消化酶的活性，检查啄壳迟早、孵化率与雏鸡卵黄囊吸收情况。

Based on the mechanism, It provided with hatchery the optimum storage conditions including the optimum storage temperature, humidity ,egg storage position, storage duration, airtight gas-control environment to keep hatching-eggs quality which make sure highest hatchability and chick-quality being achieved

如何创造最佳的贮存条件是保存种蛋质量的关键，本文揭示了最佳贮存条件的机理与蛋白质量、蛋白pH紧密相关，基于该机理，本文为孵化厂提供了保持种蛋质量的最佳保存条件，包括：最佳贮存温度、湿度、种蛋贮存位置、贮存期以及密闭的气体控制环境，以确保达到最高的孵化率及雏鸡质量。

Results of interpopulation crossing test of mating, fertilization rate, embryo growth and hatchability under the condition of cage feeding indicated that:(1) due to difference in body size, morphology, habits and characteristics and reproducing season, crossing fertility between wild Japanese quail in China and domestic quail population was lower than that of intrapopulation mating, but fertilized egg through reciprocal crossing could be incubated and produced F1 without prezygotic isolation;(2) crossing of wild male quail ?female small-type domestic quail produced the best effect among all combinations of reciprocal crossings.

通过关于笼饲环境下交配行为、受精率、胚胎发育、种蛋孵化率的种群间杂交试验证明：由于体量、形态、习性、繁殖季节性的差异，我国境内的野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反杂交，产生受精卵、孵出杂种一代，不存在合子前生殖隔离；在正反杂交组合中，以野雄鹑X小型雌家鹑的效果最好。

Of yolk (13%-88%) of pigeon eggs were replaced by yolk of Rhode Island Red, local black hen or South China Duck, the hatchability was about 60%.
