Caecal fermentation characteristics, blood composition and growth of rabbits on substitution of soya-bean meal by unconventional high-glucosinolate mustard ( Brassica juncea ) meal as protein supplement

Effect of graded levels of high-glucosinolate mustard ( Brassica juncea ) meal as substitute of soya-bean meal (SBM) in broiler rabbit diets was studied. Forty weaning rabbits of Soviet Chinchilla and White Giant breed were randomly allocated to one of four experimental diets containing mustard meal (MM) 0, 80, 160 and 245 g/kg. The experiment lasted for 8 weeks. MM had 54.8 mg total glucosinolates (TGLSs) per g dry matter (DM). Diets had TGLS 3.8, 8.4 and 11.98 mg/g DM in 80, 160 and 245 g MM diets, respectively. MM-incorporated diets had higher digestible and linearly ( P P P 3 -N ranged between 31.2 and 39.0 mg per 100 ml, and reduced linearly ( P P P P P P P
