Evaluation of Some Plant By-Products Fed For Rabbit Production

This study was carried out in twotrial aimed to evaluate the effect oftrials, the firstinclusion of someplant by-product such as orangepea-pods and fig waste atwa s te , ma 1 tdifferentby-products,levels inisonitrogenous-isocaloric diets on growth performance,carcass traits as well ammonia and total volatile fattyacids concentrations in the caecum of rabbits fed thesediets. The second trial was to evalute the nutritive value(nutrients digestibility, TDN and DCP) of the experimentaldiets and the by-products used.THE FIRST TRIAL:EXPERIMENTAL DIETS:Samples of dried, orange waste, malt by-product,brewer’s grains, pea-pods and fig waste were finely groundand prepared for chemical analys is. Then after the by-products were included at different levels, based upontheir chemical composition and estimated digestible energyvalues, in isonitrogenous isocaloric diets containing onaverage 16.83% CP, 12.55% CF and 2620 Kcal DE/kg diet.Orange waste was included at 7 and 14%, malt by-product andpea-pods were included at 10 and 16%, brewer’s grains wasincluded at 5 and 10% and fig waste was included at 10% inthe diets.
