The experiment was designed to examine the effect of types and levels of animal protein supplements on feed intake, weight gain, feed conversion ratio and feed digestibility in rats. Thirty (30) weaning albino rats of the Wister strain were subjected to five dietary treatments, diet 1 (control diet) contained soybean meal only as a source of protein concentrate, diets 2 and 3 were supplemented with 2.5% and 5.0% levels of fish meal (FM) respectively while diets 4 and 5 were supplemented with blood meal (BM) at 2.5% and 5.0%levels respectively. Animals fed on the supplemented diets at 5.0% levels of BM and FM had the highest weight gain of 3.14g and 3.0g/day respectively, followed by animals fed on supplemented diets at 2.5% levels of BM and FM (2.9g and 2.82g/day respectively). Animals fed unsupplemented soybean diet had the least weight gain of 2.51g/day. However type and levels of protein supplement had no significant effect on the growth rate of the rats.
