The growth performance of 200 local guinea fowls ( Numida meleagris ) (97 females and 103 males) were studied in an improved feeding system. The hatching body weights were 25.8 ± 3.1 g in females and 25.5 ± 2.4 g in males. The body weights at inflexion points were 523.0 ± 171.4 g in females and 497.0 ± 134.7 g in males, and the asymptotic weights were 962.0 ± 147.8 g and 857.0 ± 183.7 g, respectively. The weights at inflexion points and the asymptotic weights varied significantly (p < 0.05) depending on the variety. The daily weight gains at inflexion points were 10.1 ± 4.7 g in females and 10.2 ± 5.1 g in males, occurring at 12-14 weeks and 14-16 weeks of age, respectively, i.e. the optimum slaughtering age for each sex was within these intervals. The general average growth rate was 29.2 ± 16.8% for both sexes (30.0 ± 18.0% in females and 28.4 ± 15.9% in males). The carcass yield increased from 65.7% at 16 weeks to 74.3% at 22 weeks, and dropped to 70.4% at 56 weeks. The feed conversion ratio was 4.6 from 0 to 16 weeks in all the birds.
