Impact de rations comportant des fourrages de Pterocarpus lucens, Pterocarpus erinaceus et Ficus gnaphalocarpa sur l'embouche ovine au Mali

Abstract

Impact of Rations Containing Fodders from Pterocarpus lucens, Pterocarpus erinaceus and Ficus gnaphalocarpa on Sheep Fattening in Mali. The objective of this study was to develop sheep fattening rations that will increase food security of small size households while optimizing the contribution of fodder trees. The preferred species identified during a palatability trial were used to make sheep fattening rations by substituting partially or totally the peanut haulm with either one of the three species. Forty-nine Diallonké rams 12 to 18 months old were vaccinated, dewormed, divided into 7 groups of similar weight and fed individually with one of the 7 experimental diets for 74 days, after two weeks of adaptation: R1: control; 50% cotton seed meal (TC) et 50% groundnut hay (FA) ; R2: 50% TC + 25% FA + 25% Pterocarpus lucens; R3: 50% TC + 50% Pterocarpus lucens ; R4: 50% TC + 25% FA + 25% Ficus gnaphalocarpa ; R5: 50% TC + 50% Ficus gnaphalocarpa ; R6: 50% TC + 25% FA + 25% Pterocarpus erinaceus ; R7: 50% TC + 50% Pterocarpus erinaceus. Intakes fluctuated from 796.8 to 1028.3 g/j, which is 3.2 to 3.9 kg per 100 kg of body weight. Weight gains varied from 81.3 to 133.7 g/j. Economic efficiency, calculated from the ratio weight gain/variable costs, was low.
