Abstract

This study was conducted to investigate the effect of day length and season on haematological characteristics, biochemical and hormonal profiles of laying Guinea fowls (Numida meleagris). Four hens and 1 male were each subjected to 12 hours of light and 12 hours of darkness (12L: 12D), 14hours of light and 10 hours of darkness (14L: 10D), 16hours of light and 8 hours of darkness (16L: 8D) and 18hours of light and 6 hours of darkness (18L: 6D). Each group was replicated three times and reared in three seasons (Dry-December-March, Major rains-April-July and Minor rains-August-November) in a 3x4 factorial experiment. Data were analyzed using General Linear Model procedure of SAS. Significantly (p 0.05) in all parameters except prolactin. The findings of this study suggest that daylength of 14-16hrs and major rainy season in Ghana supports adequate haematological, biochemical and hormonal profiles of Guinea.

日长和季节变化对加纳本土珍珠鸡血液学、生化和激素性状影响的研究

本试验旨在研究日长和季节对产蛋珍珠鸡血液学、生化和激素特征的影响。4只母鸡和1只雄性分别接受12小时光照和12小时黑暗(12L: 12D)、14小时光照和10小时黑暗(14L: 10D)、16小时光照和8小时黑暗(16L: 8D)和18小时光照和6小时黑暗(18L: 6D)。每组重复3次，饲养于3个季节(12月- 3月旱季、4月- 7月雨季和8月- 11月雨季)，采用3 × 4因子试验。数据分析采用SAS通用线性模型程序。除催乳素外，其余参数均显著(p 0.05)。这项研究的结果表明，加纳的14-16小时的白天长度和主要的雨季支持几内亚足够的血液学、生化和激素特征。
