Dehydrated sainfoin in rabbit feed: effects of high incorporation on the health and performances of does and growing rabbits

Abstract

In rabbit farming, coccidiosis and fibre deficient diets (especially lignins) can increase the risk of digestive disorders. Sainfoin is a legume rich in lignins, and contains polyphenols and tannins with anti-parasitic properties. Sainfoin also contained a high level of digestible protein (79g/kg) and energy (8.84 MJ/kg). Here, we studied the effects of a high level (26%) incorporation of dehydrated sainfoin (Perly cultivar, first cut, ‘DSp’) in rabbit feeding on the performances and health of reproductive doe and growing rabbits were analysed in a sub-optimal (with coccidiosis for the two previous batches) professional breeding environment and over two non-consecutive reproductive cycles (2 replicates). Performances and health of does and growing rabbits were compared for 2 groups of 194 does and associated litters, when fed iso-nutritive feeds containing either 0 or 26% DSp. Dietary DSp incorporation had no effect on doe live weight (4,675 g), fertility rate (88.4%), mortality (6.9%), culling rate (0.8%) and doe coccidia excretions levels (P>0.05). In replicate 1, kits growth before weaning was similar (24.8 g/d) among the two groups, but was 12% lower for the DSp26 group in the 2nd replicate (significant interaction). The post-weaning growth rate was improved by 4% (37.9 vs 39.3 g/d, P=0.02) for DSp26 group. Before weaning, a higher mortality was observed for DSp26 (3.3 vs 1.8%) in replicate 1, while in replicate 2 it was lower (2.1 vs 4.4%). After weaning, the mortality rate decreased (4.5 vs 7.1%, P<0.001) for DSp26 group (mean of two replicates). Coccidia excretions of growing rabbits were not affected neither by dietary sainfoin nor by replicates. Thus, a high incorporation of dehydrated sainfoin in the feed can be recommended to improve the health and performance of growing rabbits, without affecting does performances. Sainfoin is thus a good alternative to the alfalfa meal in the rabbit feeding.
