Valorisation des ressources alimentaires locales dans l’embouche ovine paysanne : performances technico-économiques et options

Abstract

Use of local feed resources in the farmers' ram fattening scheme: technical and economical performanceThe ram-fattening scheme in Burkina Faso is currently feed-intensive using material from outside farms, such as cotton cake. In Sahelian Burkina, the high cost of this feed impedes a wide adoption of this fattening technique. Locally available feed resources such as Piliostigma reticulatum (Pr) and Acacia raddiana (Ar) are potential alternatives to cotton cake (Cc). This study aims at developing feeding strategies that incorporate local resources to partially substitute for cotton cake and identifying technically and economically efficient rations for extension. Five feed rations were allocated to 45 rams from 15 farmers. Technical and economic data were collected for performance evaluation. The results suggest that rations with 20% Ar + 20% Cc, 10% Ar + 30% Cc and 10% Pr + 30% Cc perform better technically and economically than the control consisting only of 40% Cc. Local feed resources can thus be used to partially replace cotton cake. However, the type of local feed and its level of substitution will require particular attention.

Price and quality of livestock feeds in suburban markets of West Africa’s Sahel: Case study from Bamako, Mali

“…The results of the nutritional quality of different feed types sold at the five feed markets in Bamako generally agree with results in the West African Sahel reported by other authors (3,5,17,20,23). For example, the values in our study of 284 to 390 g/kg DM for crude protein content for cottonseed cake were similar to those reported by Kiema et al (17), and Sanon et al (23).…”

Effet de la supplémentation des rations par un additif alimentaire sur la croissance pondérale et le rendement carcasse des chevreaux Roux de Maradi au Niger

“…Cependant Hani et al (2018) ont montré qu'un apport de 30 g d'acide malique par vaches laitières Holstein diminue la consommation alimentaire et augmente la production laitière. Les résultats sur l'indice de consommation de son de blé notamment 6,06 ; 5,69 ; 5,65 ; 5,45 correspondant respectivement aux lots T0, T1, T2 et T3 sont inférieurs à ceux de 12,76 ;8,42 ;7,65 et 4,17 trouvé par Nouhou (2014) chez la chèvre rousse de Maradi et ceux de Kiema et al (2008) Gnanda et al (2015) sur des ovins et qui ont oscillé entre 72 à 79 g/jr. (Zoundi, 2005) dans une étude sur les systèmes d'alimentation des ruminants au Burkina affirme que les jeunes animaux qui sont toujours en phase de croissance, expriment habituellement les meilleurs GMQ surtout lorsqu'ils sont soumis à une alimentation à haute valeur nutritive.…”

Cottonseed cake replacement by soybean pulp in the diet of West African Dwarf lambs in Benin: zootechnical and economic performances

“…Economic efficiency has been evaluated through the calculation of the gross margin (GM) and direct cost margin (Boehlje and Eidman 1984;Kiéma et al, 2008) per animal and per diet. GM is the difference between the total revenue from the sale of animals and the operational cost (costs of acquiring animals, feeds and veterinary products).…”
