The role of fibers in the growing rabbit's nutrition is very important. Dehydrated alfalfa is the mainly used source of fiber in rabbit diets, but it is too expensive in many countries. Less expensive sources are more suitable, however the determination of their nutritive value is a fondamental step for their use in feed formulation. The aim of the present study was the determination of feeding value of sundried brewer’s grain and maize silage (whole plant) for the fattening rabbit. Twenty-four, individually caged 8-week-old rabbits were used in this trial. Both wet products were sundried and grinded before they were incorporated in a basal diet. The inclusion level at the expense of all basal ingredients amounted to 30%. Basal diet and both experimental diets were fed ad libitum to 8 rabbits during the four days balance trial. The determined digestibility of protein, fat, crude fibre and NDF digestibility amounted 76.2% and 77.2%; 86.5% and 99.1%; 8.1% and 8.3% and 28.0% and 13.5%, respectively for brewer’s grain and maize silage. The digestible energy content amounted to 11.66 MJ/kg DM (brewer’s grain) and 11.10 MJ/kg DM (maize silage). Both by-products have potential as alternative feedstuff in rabbit diets.
