The feeding value of corn silage and brewer’s yeast for fattening rabbits.

Twenty-four, individually caged 8-week-old rabbits were used to determine the digestibility of brewer’s grains and corn silage. 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%. The determined digestibility of protein, fat, crude fibre and NDF digestibility was 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 grains and corn silage. The digestible energy content amounted to 11.66 MJ/kg DM (brewer’s grains) and 11.10 MJ/kg (corn silage). Both by-products have potential as alternative feedstuff in rabbit diets. However, further experiments are necessary to determine the maximal inclusion level because on the corn silage diet a tendency to decreased intake was observed.
