Photoperiod manipulation corrects the negative effect of low dietary crude protein levels during weeks 12 to 26 on bone quality and fertility of male Guinea fowl (Numida meleagris).

Improving the reproductive performance of guinea fowl (Numida meleagris) based on the management of environmental factors is important for developing meleagriculture. Thus, the present study was conducted to evaluate the effect of dietary crude protein levels and photoperiod during the 12th to 26th wk of age on growth performance, calcium and phosphorus mobilization, and fertility of local Pearl Gray male guinea fowl. In total, 120 twelve-week-old male guinea fowl were divided into 3 groups with 8 replicates each and 5 birds per replicate using a completely random design.

Dietary protein levels during 12 to 26 wk improve the growth performance, bone quality, and testosterone in Pearl Gray male guinea fowl (Numida meleagris).

Guinea fowl (Numida meleagris), although native to Africa and despite its many potentials, does not represent the dominant species on the continent because of its seasonal reproductive nature and high keets mortality. This study was conducted to assess the effect of crude protein levels on growth performance, bone characteristics and reproductive activity of Pearl Gray male breeder guinea fowl from 12 to 26 wk of age. A total of 120 twelve-wk-old guinea fowls were randomly allotted to 3 dietary treatments with 8 replicates each and 5 birds per replicate using a completely randomized design.
