The effects of divergent growth selection for 18 generations on semen characteristics, fertility and hatchability were investigated. Males from the low weight line produced semen with a significantly (P less than or equal to 0.05) higher sperm concentration and a highly significantly (P less than or equal to 0.01) lower methylene blue reduction time than the males from the high line. Differences between lines for semen volume, sperm motility, percent of live sperm, fertility and hatchability were not statistically significant.
研究了连续18代差异生长选择对精液特性、受精率和孵化率的影响。与来自高体重品系的雄性相比，来自低体重品系的雄性产生的精液精子浓度显著更高（P≤0.05），亚甲蓝还原时间极显著更低（P≤0.01）。品系间在精液体积、精子活力、活精子百分比、受精率和孵化率方面的差异无统计学意义。
