Apparent digestibility of crude protein and gross energy in some plant and animal-based feedstuffs by Clarias isheriensis (Siluriformes: Clariidae) (Sydenham 1980)

Apparent digestibility coefficient (ACD) of dry matter, crude protein and gross energy of white fish meal, blood meal, poultry by-product meal, hydrolysed feather meal, shrimp head meal, meat and bone meal, soybean meal, cottonseed meal, peanut meal, yellow maize, corn starch, cassava meal, sorghum, rice bran and cocoa pod meal were determined for Clarias isheriensis (47.5–51.2 g) fed to satiation with diets containing each test feedstuff in a 30:70 mixture with a reference diet, and chromium oxide as an indicator using the dissection technique. ADCprotein values ranged from 50 to 93 % while ADCenergy ranged from 42 to 98 %. Protein and energy content of animal or plant feed-stuffs were equally digestible to C. isheriensis.
