Trial of Using Blood from Slaughtered Chicken to Replace Fishmeal in the Feed of African Catfish Clarias Gariepinus

Abstract

The aim of the work was to reduce the cost of the food produced and to value blood from poultry. It consisted of collecting the poultry blood, turning it into flour and incorporating it into the feed intended to feed Clarias gariepinus fry. Next, an attempt was made to determine the effect of the poultry blood incorporated in the locally produced feed on the growth of Clarias gariepinus fry. To do this we substitute completely the fishmeal that was used, which is expensive with the blood meal that is found to be free. Thus, three lots of 100 Clarias gariepinus fry of 2.01g mean weight were placed in three fiberglass tubs. In each tub we have distributed a specific feed. For each type of food a quantity of 2.5kg was used. A daily ration of 5% of fry biomass was used throughout the study. They were fed 9 times a day. It is noted that the industrial food is better but there is no significant difference between locally made foods that based on fishmeal and that with poultry blood meal. So it is possible to replace fishmeal with poultry blood meal in locally made feeds.
