Abstract
In the search for an alternative dietary protein source for poultry, grasshoppers were harvested and processed into a meal (Nigeria). The approximate nutrient composition was determined. The grasshopper meal was then incorporated at 0, 25, 50 and 75 g/kg into broiler diets. Each diet was fed to triplicate groups of 10 one-day-old broiler chicks for 49 days in a completely randomized design. The grasshopper meal had high proportions of crude protein (357.6 g/kg DM) and ether extract (158.6 g/kg DM) but was low in total ash (60.2 g/kg DM) and crude fibre (10.6 g/kg DM). The grasshopper meal depressed (P<0.05) weight gain and feed efficiency. Nitrogen, crude fibre, ether extract and energy retention were significantly (P<0.05) increased but followed no particular trend. Liver weight was significantly (P<0.05) decreased while kidney, gizzard, proventriculus, and heart were not. Crude protein (g/kg DM) in the carcass increased significantly (P<0.05) as the percentage of grasshopper meal in the diet increased from 0 to 75 g/kg, whereas other components followed no particular trend. The results indicate that grasshopper meal is a possible protein source for poultry, especially broiler chickens.
