Study on Using Some Plant Products And By- Products In Fish Nutrition

Some studies evaluated leaf protein concentrate (LPC) from rye grass as dietary feed ingredient for common carp and rainbow trout and the results were LPC replace up to 43% and 40% of the total protrin in diets for carp and rainbow trout, without any loss in growth or feed conversion ration when compared with casien control ration. extracted LPC from cassva and fodder beet leaves and showed its efficincy in formulation of economical diets for ruminant feeding.In view of the absence of information concluded that cassava root meal(CRM) suitable feed components which replace up to 20% of yellow corn in common carp diets. This work aimed at Using untraditional laf protein concentrates as a replacement of high cost protein source (soybean meal), Using untraditional energy concetrates (cassava root meal) replacing high cost of maize grains.
