Hatchery debris analysis

this biological trial was conducted with native chicken population at Department of Poultry Science, Veterinary College and Research Institute, Namakkal for a period of 52 weeks. This explains how the fertility and hatchability of native chicken were influenced by age and body weight of the parent birds. This hatchery debris was analysed for about 25 weeks period from 27 to 52nd week of age. It was concluded that other than 3-5 days and middle mortality, all hatchability parameters were influence by age and body weight of parents.

这项生物学试验以本地鸡群体为研究对象，于Namakkal兽医学院与研究所家禽科学系开展，试验周期为52周。该试验旨在阐明亲代鸡的年龄与体重对本地鸡繁殖力（fertility）和孵化率（hatchability）的影响机制。研究人员对孵化场废弃物（hatchery debris）进行了为期约25周的分析，时间跨度为试验鸡群27周至52周龄。研究结论表明，除3-5日龄及中期死亡率外，所有孵化率相关参数均受亲代鸡年龄与体重的影响。
