Partial and complete replacement of clover leaf (Trifolium alexandrinum) meal protein by cabbage leaf (Brassica oleracea) meal protein in Nile tilapia diets together with economic evaluation

Soliman A.K., Mohamed A.I., Abou Akkada A.R., Badawy A.M.

Five diets were formulated including 0.0, 6.5, 13.5, 19.5 and 26 percent of cabbage leaf meal (CLM) instead of 0.0, 3.0, 6.0, 9.0 and 12 percent of Egyptian clover leaf meal (ECLM). Fish fed on the diet where 3 percent of ECLM was replaced by CLM showed the best body weight and specific growth rate compared with the ECLM diet. Survival rates, food conversion and protein efficiency ratios showed no significant differences. Variable results were noticed in apparent net protein utilization between diets. Fish fed on the 13.5 percent CLM diet had the highest carcass ash. No significant differences were found in hepatosomatic and blood parameters of fish fed on experimental diets but these exhibited significant differences in plasma glucose, pyruvic glutamic transaminase and carotene levels. The cost/kg of feed was reduced by increasing CLM content. The best profit index was obtained by diets containing the highest level of CLM.
