This study was conducted to investigate the influence of different lighting regime on reproductive and growth performance of the pearl Guinea fowl (Numida meleagris) in Ghana. A total of five hundred (500) eggs were collected from an ongoing photoperiod experiment which were hatched and used for the study. The experimental birds were randomly assigned to a lighting programme of 12 hours of light: 12 hours of darkness (12L: 12D), 14 hours of light: 10 hours of darkness (14L: 10D), 16 hours of light: 8 hours of darkness (16L: 8D), and 18 hours of light: 6 hours of darkness (18L: 6D). A total of two-hundred and forty (240) day one old keets were divided into four treatment groups and each treatment was replicated three times in a Completely Randomize Design (CRD). The data collected were subjected to analysis of variance (ANOVA) using GenStat version 11.1 (2008). Least significant difference (LSD) at 5 % was used to separate the means. Results from the study revealed that, Percentage fertility, hatchability and hen-day egg production was highest (P<0.05) among Guinea fowls subjected to 16L: 8D photoperiodic lighting schedule. Egg weight, dead in shell and piped eggs were highest (P<0.05) among Guinea fowls subjected to 12L: 12D photoperiodic lighting schedule. Guinea fowls subjected to 18L: 6D lighting schedule had the highest (P<0.05) body weight, body weight gain, feed intake with better feed conversion ratio. This study concludes that 16L: 8D improves fertility, hatchability and hen-day egg production while 18L: 6D ensures rapid growth with better feed conversion.
