Investigation of early feed intake : does suckling rabbit have pellet preferences?

Abstract : Health management is the main challenge facing rabbit breeding. To handle this issue, our objective is to stimulate pups’ solid feed intake to accelerate the maturation of digestive microbiota towards a stable state. In order to determine attractive pellet presentation for suckling rabbits, two preference tests were carried out, using a motherlitter separate feeding system. We provided pellets from 3 to 18 d-old in the nest box, and from 15 to 35 d-old in the cage. In the first trial, four pellet diameters were used: (A) 2.0 mm, (B) 3.0 mm, (C) 4.0 mm, (D) 6.0 mm. The pellets were tested in pairs against each other (6 groups of 10 litters). In the second trial, we tested in pairs pellets of same diameter (either 2.5 mm or 4.0 mm) manufactured with different channel lengths (10/12/14 mm for 2.5 mm diameter pellets, 18/20/24 mm for 4 mm pellets – in total 6 groups of 10 litters) to ensure different pellet quality. Feed consumption in the nest was measured daily, and every 4 days after nest removal at 21 d-old. Milk intake was measured twice a week. Birth-weaning mortality, young rabbit growth and milk intake did not differ between treatments (NS). Solid feed intake started from 8 days of age (45 out of 120 litters with a significant consumption). Total feed ingestion in the nest was 2.1±0.6 g DM/rabbit (Trial 1) and 1.5±0.1 g DM/rabbit (Trial 2). In the cage feeders, pellet A showed higher relative consumptions (RC) (61, 67, and 86% when compared with B, C and D), and clear preferences for small pellets over D were found within groups (P<0.001). In Trial 2, from 7 to 35 d-old, a lower RC (-24%; P<0.05) was found for 4.0 mm diameter pellets processed with the longest die channel (24 mm). Our results indicate that kits solid feed intake can start at 8 days of age and may be modulated according to suitable pellet presentation (e.g. small diameter…).
