ABSTRACT
The valorization of non-conventional feedstuffs, such as Dacryodes edulis oil cake, as a local source of crude protein, may be one way to improve poultry production, such as guinea fowl meat, in developing countries. The present study aimed to evaluate the effect of Dacryodes edulis oil cake by incorporating gradual amounts into the diets of common guinea fowl. The study involved sixty 4-week-old Hubbard broiler guinea fowl, randomly divided into three groups of 30 each. Diets contained 5% and 15% of Dacryodes edulis pulp cake during the growth phase, and 10% and 18% during the finishing phase. The guinea fowl were compared based on growth and economic parameters. The results showed that the incorporation of Dacryodes edulis meal at 15% in the growth phase and 18% in the finishing phase induced significant (p <0.05) differences in all variables at the 5% threshold. In addition, the treatment significantly (p <0.05) improved final live weight (1571g vs. 1400g), ADG (32g/d vs. 26g/d), voluntary feed intake (160g/d vs. 139g/d), and feed conversion ratio (4.8 vs. 5.3). The incorporation of Dacryodes edulis meal reduced feed costs by 8% and 9% in the growth and finishing phases, respectively, compared to the control. This study opens up interesting prospects for fruit and poultry farming in tropical zones.
