Nutrient Utilization and Growth response of Clarias gariepinus Fed African Breadfruit (Treculia africana) Seed Meal Diets

摘要

The nutrient utilization and growth response of fingerlings of Clarias gariepinus to cooked African Breadfruit Seed Meal (ABSM) diets was investigated. Cooked ABSM which is the test ingredient was included at 0, 20, 40, 60 and 80% in 5 diets formulated at 40% crude protein level and the diets were used to feed the fish. Each treatment was replicated twice and the experiment lasted for 70 days. Fish fed D2 (20% inclusion level) had the best growth rate with SGR of 1.66±0.04, FCR of 2.04±0.06 and PER of 0.61±0.03 followed by the fish fed the control diet (0% inclusion level) while fish fed diets D5 (80% inclusion level) had the least growth rate with SGR of 1.31±0.04, FCR of 2.95±0.08 and PER of 0.42±0.01. It can be concluded that African breadfruits seed meal can replace maize at 20% inclusion level as an energy source in the diet of Clarias gariepinus fingerlings.
