Evaluation of poultry viscera as potential fish feed ingredient, compared to fishmeal

A study was conducted to observe the nutritive value of commonly used fish feed ingredients. High nutrient contents, easy availability and low cost were the major considerations in selecting the fish feed ingredients. During the present study the crude protein percentage of the poultry viscera, fishmeal, mustard oil cake, wheat bran, wheat flour and rice bran was estimated 60.67 %; 55.19 %; 34.86 %; 15.29 %; 15.19 %; 11.37 % respectively. The crude lipid percentage was recorded as 12.05 % in poultry viscera, 7.77 % in fishmeal, 11.77 % in mustard oil cake, 6.85 % in wheat bran, 3.35 % in wheat flour and 10.05 % in rice bran. The proximate composition of the experimented ingredients signified crude protein as the main factor, as the feed cost confirmed restrictions against the superior improvement of fish farming. Fishmeal is traditionally the major animal protein supplement in fish diets, but it is inadequate and expensive. Therefore different types of poultry wastes have been tested, and poultry viscera appeared as an alternate potential protein source, stimulating the poultry waste recycling.
