Abstract

This study evaluated the effect of proximate analysis and wood ash extract soaking varying durations (24, 48, and 72 hours) of pigeon pea (Cajanus cajan) seeds on the performance of broiler chickens. Raw pigeon pea seeds were soaked in wood ash extract at pH 8.5 for 24, 48, and 72 hours, sun-dried, and incorporated into broiler diets replacing soyabean at 50% at the three levels. A total of 144 day-old Anak 2000 broiler chicks were randomly assigned to four dietary treatments in a completely randomized design with three replicates of 12 birds each. Proximate analysis revealed that soaking significantly (P<0.05) influenced crude protein, crude fibre, ether extract, ash content, nitrogen-free extract, and metabolizable energy of pigeon pea seeds. The 72-hour soaking period yielded the highest crude protein content (25.57%). Performance characteristics showed that birds fed the 72-hour soaked pigeon pea meal (APPM₃) had significantly (P<0.05) higher final live body weight (868.28g±0.25 for starter; 2018.75g±2.16 for finisher) and daily body weight gain compared to other treatments. Feed conversion ratio and protein efficiency ratio were favorably influenced by the dietary treatments. The findings suggest that soaking pigeon pea seeds in wood ash extract for 72hours duration optimally enhances their nutritive value and improves broiler chicken performance compared to other treatments, offered better alternative to conventional soya bean meal.

 

 

 

 

Cette étude a évalué l’effet de l’analyse proximale et du trempage de durées variables (24, 48 et 72 heures) de graines de pois d’Angole (Cajanus cajan) dans un extrait de cendre de bois sur les performances de poulets de chair. Des graines de pois d’Angole crues ont été trempées dans un extrait de cendre de bois à pH 8,5 pendant 24, 48 et 72 heures, séchées au soleil, et incorporées dans des aliments pour poulets de chair en remplaçant le soja à 50 % aux trois niveaux. Un total de 144 poussins de chair Anak 2000 âgés d’un jour ont été répartis aléatoirement selon quatre traitements alimentaires dans un dispositif complètement randomisé avec trois répétitions de 12 oiseaux chacune. L’analyse proximale a révélé que le trempage influençait significativement (P<0,05) les teneurs en protéines brutes, fibres brutes, extrait éthéré, cendres, extrait non azoté et l’énergie métabolisable des graines de pois d’Angole. La période de trempage de 72 heures a donné la teneur en protéines brutes la plus élevée (25,57 %). Les caractéristiques de performance ont montré que les oiseaux nourris avec le tourteau de pois d’Angole trempé 72 heures (APPM3) avaient un poids vif final significativement plus élevé (P<0,05) (868,28 g ± 0.25 pour le démarrage ; 2018,75 g ± 2.16 pour la finition) et un gain de poids quotidien supérieur comparé aux autres traitements. L’indice de consommation et le taux d’efficacité protéique ont été favorablement influencés par les traitements alimentaires. Les résultats suggèrent que le trempage des graines de pois d’Angole dans l’extrait de cendre de bois pendant 72 heures améliore de manière optimale leur valeur nutritive et améliore les performances des poulets de chair par rapport aux autres traitements, offrant une meilleure alternative au tourteau de soja conventionnel.
