Abstract

Fish may need a time to adapt to experimental diets when digestibility and /or faeces characteristics are being measured. The main goal of this study is to investigate the influence of adaptation time on the digestibility and faeces recovery in diets contained two types and levels of starch. Four experimental diets were formulated using two types (raw and gelatinized) and levels (20 and 40%) of maize starch. After 2-wk adaptation, faeces was collected during a 5-wk period. The apparent digestibility (ADC) measurements and the faeces recovery were estimated using settling tanks in the current study. ADC measurements increased significantly for all diets by the end of the experiment (P <0.05). However, the impact of adaptation time on ADC values is highly related to the type of the diet. Faeces recovery did not change over the experimental period (p > 0.05), except for 40% gelatinized diet. Total faeces production reduced gradually up to the final week of measurement for the tested diets (P
