Feeding Rapeseed Meal to Rabbits: Digestibility, Performance and Carcass Characteristics

Aziza Gasmi-Boubaker, H. Abdouli, M. El Hichi, K. Faiza and L. Tayachi
Two experiments were conducted to investigate the effects of different levels of Rapeseed Meal (RSM), as a source of protein, on digestibility (Experiment 1), performance and carcass characteristics (Experiment 2) in rabbits. Dietary Soybean Meal (SBM) was replaced with RSM at 0, 7, 14 and 21% (dry matter basis). No differences were obtained for Crude Protein Digestibility (CPD) coefficients of experimental diets. However, Dry Matter Digestibility (DMD) and Organic Matter Digestibility (OMD) decreased in diet containing 21% RSM. The daily weight gain values ranged between 27.1 and 28.5 g and tended to decrease as the level of RSM increased in the diet. The feed efficiency was not significantly affected by the inclusion of RSM, although rabbits on 21% RSM diet had the poorest efficiency (4.8) while the best feed efficiency (4.6) was obtained from the rabbits fed on RSM diet. The percentage values of liver and peripheral fat were not affected by the diet. The results showed that RSM could replace up to 14% of dietary soybean meal in the diets of rabbits without adverse effects on digestibility, performance and carcass characteristics.
