Abstract
A caecal fermentation study was conducted in 30 Angora rabbits equally placed under five whole diets (75 concentrate : 25 roughage) supplemented with processed Neem (Azadirachta indica) kernel meal (NKM ; 2% urea or 1.5% NaOH, W/W), replacing isonitrogenously either at 50 or 100% level of deoiled peanut (Arachis hypogea) meal, for 18 wk period. The total volatile fatty acids level was depressed (p < 0.05) in all the experimental groups (0.02 to 0.04 mEq/g) and ammonia-nitrogen was lowest (p < 0.05; 24.9 關mol/g) in rabbits fed NaOH treated NKM supplemented diet. Enzyme activity (unit/g) of carboxy methyl-cellulase, 慣-amylase, protease and urease exhibited much variation and did not differ significantly. Hence, the results could not confirm a possible adverse effect of feeding NKM on caecal fermentation.
