Abstract

The main objective of this study was to assess the nutritional value of four protein sources (soyabean meal, fish silage, sardine fish and fishmeal) using commercial broiler and local poultry strains. Four experimental diets were formulated; representing four different proteins sources and was evaluated using six replicates of eight birds per cage at 21 day of age. Cages were located in an environmentally controlled room maintained under conditions suitable for birds at this age with a photo-period of 23 h in every 24 h. Diets and water were offered on ad libitum basis. On the fourth day after the adaptation to the experimental diets, feed troughs were removed from every cage for 1 h and then reintroduced for 2 h. Then the birds were killed to allow for sampling of ileal digesta, from Meckel's diverticulum to the ileal-caecal-colonic injunction. Broiler birds showed significantly (p
