Abstract Protein in the diet (25 Vs 31%), stocking rate (100 Vs 200 fish per m3) and inclusion rate of pantothenic acid, vitamin B5, (10 Vs 20 mg/kg diet) were compared for their effects on blood plasma protein, albumin, urea-N, creatinine, plasma transaminase enzymes (AST and ALT), thyroxin (T3) and growth in Oreochromis niloticus juveniles. Blood total protein, albumin, ALT, T3 and growth were ...

What is Nutrient level of Nile Tilapia for floating fish feed? We have rich source of Corn, Soyacake, Broken Wheat, Rapeseed, Wheat flour red and Soya oil. All of those raw materials can be used floating fish feed at maximum level.

Good article about Nile Tilapia. Can this dietary protein level enhance the immune response in fish diseases ?

The nutrient level for Nile Tilapia fish differ according to the fish age and the water quality. The protein level ranged from 25 to 40%, the energy level 3300-4200 Kcal/kg diet. I think that soyacake, corn and broken wheat are the common feed tilapia fish, but soy oil is expensive for using in the fish diets.

Interesting article about Nile Tilapia. Think that protein content in fish diets did not related with the immune system in fish. But some feed additives such as pantothenic acid, vitamin E, vitamin C, zinc, copper increased the immune system in fish
