The potential anticoccidial effect of tannin containing resources such as sainfoin and carob in rabbits feed given to does at pre-weaning and to growing rabbits were tested. The trial started at parturition (D0), 24 does and their litters were assigned into three groups. They were fed either with a control (Group CO), a carob (containing 10% carob pods meal) (Group RO) or a sainfoin diet (containing 34% dehydrated sainfoin pellets) (Group SA). All diets were made isonitrogenous and isoenergetic and also balanced for crude fibre, but differed by their tannins content. Weaning occurred at D37, and growing rabbits remained in the same cage until D51, and then were transferred to fattening cages until the end of the trial. Weight gain of young rabbits among the three groups did not differ. Economical FCR post-weaning was reduced for rabbits of group SA compared to CO and RO groups. Faecal oocyst count in group SA was 60% lower than in CO and RO groups. Areas under the curve (AUCs) for oocysts counts calculated when rabbits remained in maternity cages after weaning did not differ according to diet. AUCs calculated after rabbit transfer in fattening cage was 62% lower in group SA than in CO and RO groups. The main species identified (from D59 to D83) was E. magna (53% of oocysts). AUCs for E. magna did not differ between diets. In conclusion, incorporation of sainfoin in a balanced rabbit diet can lower oocyst excretion of coccidia by 60%, and ameliorated the economical FCR.
