Valorisation de l’herbe par des monogastriques en agriculture biologique : des expériences à prolonger

Abstract : In organic agricultural systems, swine and poultry must have access to roughage; in the case of rabbits, roughage must constitute 60% of the diet. Allowing access to forage could be a mechanism for reducing feed-related costs and the need to provide protein via complete feed. One issue is that the nutritional values of different forage types are poorly characterised for these monogastric species. However, based on available data, swine and poultry can at least partially exploit forage-based protein (digestibility: about 50% and 75%, respectively), even though they are not herbivorous. For rabbits, which are herbivorous, the nutritional value of forage is high. Different methods of allowing forage access could be used: turning animals out to grass or through feeding. However, several other issues must be explored before clear recommendations can be made to livestock farmers.
