The aim of this study was to evaluate the effects of different agro-industrial by-products in diets and to determine the nutritive value and energy contained in feeds for meat production and the biochemical parameters in the digestive tract of rabbits. The fattening experiment was started at 35 days of rabbits’ age and finished by the achievement of 2 500 ± 50 g of live weight (no later than at 84 days of rabbits’ age). Rabbits had ad libitum access to complete granulated diets and water during test time. Research was carried out with two meat rabbit lines. The utilization of agro-industrial by-products may be economically worthwhile, since conventional feedstuffs are often expensive. Several factors - such as pollution abatement and regulations, increasing costs of waste disposal and changes in perception of the value of by-product feedstuffs as economical feed alternatives - have led to increased interest in by-product feedstuffs. In all groups the animals were of comparable growth performance, health status (morbidity, mortality). However, total caecal VFA concentration was significantly higher (P≤0.01) and the pH lower in rabbits fed dried sugar beet pulp, wheat bran, dried apple pomace diet than in the caecum of other rabbits (P≤0.01). Similarly, caecal ammonia concentration decreased when rabbits received diet with dried sugar beet pulp (P≤0.01).
