Growth performance and physiological responses of helmeted guinea fowl () to different stocking densities in humid tropical environment

Commercialisation of helmeted guinea fowl production in Africa is still in its rudimentary stage and there is a dearth of information on the optimal stocking density of the birds. This study was conducted to evaluate the effect of stocking density on the physiological responses and performance of guinea fowl. A total of 240 indigenous guinea fowl were used for this study.

Data were collected on growth performance, haematochemical profile and plasma triiodothyronine of the birds. The results showed that from the 7th to the 13th week, birds stocked at 14 and 16 birds/m2 were significantly (P  16 birds / m2 > 18 birds/m2 > 20 birds/m2. Feed conversion ratios of the birds increased with stocking densities. Heterophil/lymphocyte ratio significantly increased with stocking density.
