【摘要】 笼养黑颈长尾雉于三月中下旬开始产卵 ,五月下旬产卵结束。其产卵数和受精率与其繁殖发情的高峰期有一定相关性。对 1 996- 1 998年按 1♂ :2 - 3♀配比的 2笼 5只 3龄雉 ;2 0 0 1～ 2 0 0 3年按 1♂ :3- 4♀配比的 6笼 2 1只 1 - 3龄以上黑颈长尾雉所产的卵及受精率进行比较和研究。同一繁殖期 ,不同个体或同一繁殖群在不同繁殖期 ,其产卵数与产卵日期不同 ;不同龄期 (一龄、二龄、三龄 )其产卵数和受精率不同。三龄雉最高 ,一龄雉最底 ,二龄雉居中。雌雄雉的配比对卵的受精率有较大影响 ,按 1♂ :2 - 3♀的配比方式进行饲养 ,以提高笼养黑颈长尾雉的繁殖率。更多还原

【Abstract】 Black-necked Bar-tailed Pheasant lay eggs from late of March to May. There was a certain relationship between amount of eggs, fertilized rate and the peak time of estrus. Compared the data of 5 individuals of 3 year-old from 2 cages with 1♂:2-3♀ in 1996-1998 with 21 individuals of 1-3 year-old from 6 cages with 1♂:2-3♀ in 2001-2003, we found that duration of laying egg and amount of egg varied among in different individual in the same year and same individuals in different years, the amount of egg and fertilized rate were different among the deferent ages as well with the highest in 3 year-old and lowest in 1 year-old. The artificial mating rate had important impact on fertilized rate and the mating rate of 1♂:2-3♀ would be the best for the peasant breeding.更多还原
