The nutrition of turkeys involved the use of high crude protein corn-soybean based diets to achieve efficient feed conversion and improved growth. Unfortunately, the main protein sources used in turkey diets (fish meal and soybean meal) are very expensive hence there is a need to explore cheaper alternatives such as shrimp waste meal (SWM). It was hypothesized that Nigerian Indigenous turkeys could comfortably handle the residual chitin in SWM than the exotic breed due to their hardy nature. This study therefore seeks to investigate metabolizable energy values and apparent nutrient digestibility of diets containing varying inclusion of SWM (replacing fish meal) in the nutrition of growing turkeys. Four diets were formulated such that FM in the control diet (diet 1) was substituted by SWM at 150, 300 and 450g/kg (protein for protein) in diets 2, 3, and 4 respectively. Eighty-four weeks old mixed sex British United Turkeys (BUT) and 80 Nigerian Indigenous Turkeys (NIT) were allotted on weight equalization into four dietary treatments replicated four times with five turkeys per replicate in a 2 x4 factorial arrangement. The study was carried out in phases (starter, grower and finisher). Total faecal collection method was used for apparent, true nutrient digestibility and metabolizable energy values. Proximate composition of faecal samples was used to compute the apparent nutrient digestibility of dry matter, crude fibre, crude protein, ether extract and ash. At the starter phase, NIT recorded significant (P |
