| Abstract | ||
| As experiment was conducted to evaluate the usage of dried baker's yeast (DBY) a feed additive in tilapia fingerling diets. Four experimental diets were formulated to be isocaloric Diet, and served as a control one, while diets 2,3 and 4 contained 1,2 and 3% DBY respectively. Diets were fed for an 8-week experimental period: Fish fed on diets containing 3% DBY showed very high mortality eves with fish replacement. Fish fed on the control! diet showed the best performance parameters (final body weight, weight gain, increase in total body length, FCR, and PER). Fish fed on diets containing 1% DBY showed a close performance as control group while 27% DBY showed a negative effect. Apparent digestibility coefficient (ADC) was determined for experimental diets using chromic oxide as an indicator. The results revealed that DBY at level of 1 or 2 % did not significantly affect the ADC of DM, GE, EE, and CP of the diets. | ||
