Ingestion volontaire et digestibilité apparente d'une ration à base de la farine de graines de Mucuna pruriens var. utilis complétée de fourrages chez les lapins
Abstract
Volontary Ingestion and Apparent Digestibility of a Ration Based on Mucuna pruriens var. utilis Seeds Flour Completed with Forage on Rabbits. Mucuna pruriens var. utilis (mucuna) detoxified seeds flour is used as a vegetable protein source, in a basal diet of fifteen growing rabbits divided in five groups of tree. Each rabbit received per day a fixed quantity of basal diet (130.5 g DM), but as only feed (RP) for control group; plus 40.5 g DM of Panicum maximum forage and, 60 g DM of one of the four experimental legumes of Aeschynomene histrix (RH), Mucuna pruriens (RFM), Stylosanthes scabra Secca (RS) and Tridax procumbens (RT) for the others groups. The experiment conducted in Benin has lasted 26 days, split in 19 days for diet adaptability and 7 days for data collection. Voluntary daily feed intake varied from 28 to 42 g/kg of dry mater (DM) of live weight (LW) for basal diet and from 10.5 to 18 g DM/kg of LW for Panicum maximum. Green forage consumption of Aeschynomene histrix, Mucuna pruriens and Stylosanthes scabra were higher compared to the one of Tridax procumbens (P< 0.01). The supply of green forage to basal diet has increased the total daily feed intake that is about 67 to 89 g DM/kg of LW and 26 to 39 g DM/day for dung production.Water intake is higher for rabbit fed with RP diet. Feed resource RFM but also RS and RH have been digestible with 70%, 61% and 54% DM. They gave high weight gain of 30-22 g/day.
