This study was conducted to evaluate the effect of microbially fermented spent mushroom substrate by-products supplemented diet on growth performance, feed efficiency and economics of native goats for 45 days The experiment was laid out in a randomized complete block design with the following treatments T-100% napier grass. T-200 grams concentrates+ 100% napier grass, T- 200 grams concentrates + 10% EM-SMS mixture 90% napier grass, T. 200 grams concentrates +10% SMS molasses mixture 90% napier grass, T-200 grams concentrates+ 10% molasses+90% napier Grass. Each block had (5) five treatments containing one (1) experimental unit. Result showed the mean weights of all treatment groups showed increase in the weights which were expected since the animals were given rations for maintenance and growth. Average daily gain shows that animals given with combination diets of grass, feed concentrates, EM-SMS, and molasses had comparable average weight in gain with animals fed with grass, feed concentrates, and molasses During the 10th day, no significant differences among treatments were observed However, at days 17 to 45, highly significant differences among treatments were observed which means that different diet regimens have significantly affected the gain in weight of the different treatment groups. Protein efficiency ration it shows that treatment 4 has the highest protein consumed. Consequently, this treatment has the highest crude protein content the improves substantially the nutritive value of these feeds resulting to the highest of the animal weight gain compared to other treatments.
