本研究旨在探讨不同配种模式对慢羽系淮南麻黄鸡产蛋性能、蛋品质和福利水平的影响。360只196日龄慢羽系淮南麻黄鸡母鸡和40只公鸡等分为本交笼组和人工授精组,测定两组的产蛋性能、死亡率、蛋品质和福利水平。结果显示:与人工授精组相比,本交笼组试验鸡的开产日龄较早,产蛋率、受精率和母鸡死亡率较低,蛋黄颜色显著较深,其他指标差异不显著。福利水平测定结果表明:本交笼组淮南麻黄鸡各个部位脱羽评分与人工授精组差异不显著,但全身脱羽评分显著低于人工授精组。此外,本交笼组鸡群的惊恐程度显著高于人工授精组。结果提示:配种模式是影响淮南麻黄鸡部分产蛋性能、蛋品质以及福利水平的重要因素,建议应用人工授精模式。
The aim of this study was to investigate the effects of different breeding patterns on egg production, egg quality and welfare of slow-heading Huainan hen. Three hundred and sixty-six-day-old slow-feathering Huainan hemp chicken and 40 roosters were divided into the delivery cage group and the artificial insemination group. The egg production, mortality, egg quality and welfare of the two groups were measured. The results showed that compared with the artificial insemination group, the experimental group had a higher early-opening day, lower egg production rate, fertilization rate and hen mortality, darker egg yolk color and no significant difference between the other indexes. Welfare level determination results showed that there was no significant difference between feather score and artificial insemination group in all parts of Huainan cassava group, but the body feather feather score was significantly lower than that in artificial insemination group. In addition, the degree of panic in this cage group was significantly higher than that in the artificial insemination group. The results suggest that the mode of mating is an important factor that affects part of egg laying performance, egg quality and welfare of Huainan hen roast chicken. It is suggested that artificial insemination mode should be applied.
