Utilisation of 3 diets based on different protein sources by Algerian local growing rabbits

Berchiche M., Lounaouci G., Lebas F., Lamboley B.

Three isonitrogenous (crude protein: 18.5 per cent DM) and isofibrous (crude fibre: 10.5 per cent DM) balanced diets were formulated and manufactured in Algeria with soya meal, field beans or brewer's grains as main protein source, in complement to dehydrated alfalfa and wheat bran. Diets were distributed ad libitum to 3 x 21 Algerian local rabbits from 5 weeks (weaning) until 13 weeks of age (slaughter). All rabbits were caged individually. Digestibility was determined with 7 rabbits per diet according to the standardised European method for dry matter, energy (67.2 - 70.9 - 67.7 per cent for the 3 diets in the above order; P<0.01), nitrogen (77.3 per cent on average) and crude fibre (22.6 per cent on average). The protein source had no significant effect on growth rate (26 to 28 g/day) or on feed conversion ratio (3.9 g/g on average). Likewise, slaughter performances were similar for the 3 diets : mean slaughter yield was 64.2 per cent and mean carcass weight was 1234 g (commercial presentation without legs extremities). It was concluded that rabbits of the local population are able to provide acceptable carcasses (1.2 kg - 2 per cent kidney fat on average) if feeding with balanced pelleted feeds is prolonged until 13 weeks of age. The other conclusion was that field beans and especially brewer's grains are suitable ingredients for local production of balanced feeds.
