INRAE has conducted from 2002 a research program to improve the feeding strategies for the growing rabbit, aiming to reduce the risk of digestive disorders (diarrhoea) without using drugs. Studies demonstrated that an adequate control of the post-weaning feed intake reduces the risk of digestive diseases while improving feed efficiency. INRAE performs thus an impact analysis of this innovation over the past ten years. Results showed that feed intake regulation strategies (FIRS) have led to both a reduction in the losses of growing rabbits (720000 rabbits saved/year, 30M€ over 2005-2015) a reduction in the use of drugs (-50% antibiotics used for digestive disorders) and a reduction in feed costs (+ 5% of feed efficiency, 40M€ saved). FIRS also impacted favourably the environment (-9% of global warming potential,-11% of eutrophication potentials). FIRS therefore combines economic (10M€/year), environmental and social benefits for French conventional rabbit farming systems.
