Apparent digestibility coefficients of different processed African locust bean (Parkia biglobosa) seed meal by Clarias gariepinus fingerlings

Abstract

This study investigates the apparent digestibility coefficient of different processed African locust bean seed meal by Clarias gariepinus fingerlings. Diets containing 40% crude protein were formulated with Chromic oxide (Cr203) use as an inert marker at 1% inclusion in the reference and experimental diets. The five experimental diets containing 70% reference diets and 30% of the test diets. All data were subjected to a one-way analysis of variance. The Apparent Digestibility coefficient (ADC) values protein were significantly highest in fish fed diet II and III with 80.764±0.012 and 81.175±0.091 and lower in fish fed diet IV with 71.613±0.095. ADCs fat was significantly highest in fish fed diet II with 83.619±0.026 and lowest in fish fed diet I with 75.732±0.101. ADCs gross energy was significantly higher in fish fed diet II with 76.896±0.084 and lower I fish fed diet 71.138±0.084. ADCs calcium was significantly higher in fish fed diet V with 87.497±0.430 and lower in fish fed diet with 83.171±0.402. ADCs values for phosphorus were significantly higher in fish fed V with 90.122±0.087 and lowest in fish fed diet I with 87.154±0.237. In conclusion, the processed Parkia bigblobosa seed meal was digested, and they can be used as a partial protein source for Clarias gariepinus diets
