Utilization of Ginger Extract in Nile Tilapia (Oreochromis niloticus) Diets
Faculty of Agriculture, Al-Azhar University, Nasr City, Cairo, Egypt.
Abstract
A feeding trial was carried out to study the effect of dietary inclusion of different levels of ginger on growth performance, feed, nutrient utilization, body composition and cost benefit analysis of the Nile tilapia. Nine hapa (3×3×1 m3) were used, each was stocked with 50 fish (overage initial weight 10 g/fish). Nine experimental diets were formulated to contain (0.5 and 10% of ginger extract protein instead of soybean meal protein). All the diets were isonitrogenous (30% protein) and isocaloric (4500 Kcal/kg) diet, gross energy. Fish were fed on the experimental diets at a rate of 5% of their body weight daily for 16 weeks. The feed amount was given at two times daily. Nile tilapia fed the diet containing (1%) ginger extract exhibited the best performance, feed conversion, and protein efficiency ratio compared with the control and level 0.5% ginger in fish diets. The body composition was not affected by ginger extract up to 0.5% inclusion level. However, the higher level of ginger inclusion caused high protein and low lipid contents of fish body than the control diet. Cost benefit analysis showed high profil index and low incidence cost with the ginger inclusion in the diets.
