The purpose of this study was to see how day length and season affected the haematological, biochemical, and hormonal profiles of laying Guinea fowls (Numida meleagris). Each of the four hens and one male was given 12 hours of light and 12 hours of darkness (12L: 12D), 14 hours of light and 10 hours of darkness (14L: 10D), 16 hours of light and 8 hours of darkness (16L: 8D), and 18 hours of light and 6 hours of darkness (18L: 6D) (18L: 6D). In a 3x4 factorial experiment, each group was reproduced three times and reared in three seasons (dry December-March, major rains April-July, and minor rains August-November). SAS's General Linear Model technique was used to examine the data. Higher by a significant amount (p0.05). 16L: 8D had the greatest (p0.05) packed cell volume (PCV), lymphocytes and eosinophils, total serum protein, and prolactin levels, whereas 14L: 10D had the highest (p0.05) neutrophil and albumin. In heavy rains, PCV and platelets were highest (p0.05), whereas red blood cells and neutrophils were highest (p0.05) in dry and minor rainy seasons, respectively. Between the dry and minor rainy seasons, total serum protein rose (p0.05). Major rains had the highest levels of oestrogen and luteinizing hormones (p0.05), while minor rains had the highest levels of prolactin (p0.05) and major rains had the lowest levels. Except for prolactin, the interaction effect was not significant (p>0.05). According to the conclusions of this study, a daylength of 14-16 hours and a substantial rainy season in Ghana sustain acceptable haematological, biochemical, and hormonal profiles of Guinea.
