Different starch sources affect physical characteristics of extruded feeds prepared for the Malaysian mahseer, Tor tambroides

Starches from three local crops (sago, Metroxylon sagu; cassava, Manihot esculenta; and taro, Colocasia esculenta) were tested as replacements for corn starch in the production of extruded feed for the Malaysian mahseer, Tor tambroides . Four test feeds were formulated to contain 40.00% protein and...
