Growth pattern of helmeted guinea fowl keets was studied in an open air system (OAS) and a deep litter system (DLS). A common growth pattern was obtained in both systems indicating that the birds can be reared successfully for meat production in either of the two systems. Reproductive parameters and levels of circulating estradiol, progesterone, testosterone and luteinizing hormone (LH) were studied in adult helmeted guinea fowl in the OAS and DLS. Reproductive cycles were obtained in the OAS during rainy seasons. Egg fertility was 35% and hatch rate of fertile eggs was 89%. Females in the...
