ABSTRACT
Fish waste were mixed with molasses and fermented with a starter culture made of Lactobacillus plantarum. Chemical an microbiological characteristics of the obtained product were determined. The formers included pH, total nitrogen, total volatile nitrogen, non protein nitrogen, fat carbohydrates and the dry matter and the laters concerned the plate count, coliforms, Salmonella, Clostridium, yeasts and lactics. The obtained product was used for substituing some protein sources in a conventional commercial formula in three formula an a control corresponding respectively to 0, 5, 15 and 25 %. The prepared formula were used in feeding broilers. Four lots of 10 broilers each were used. The weight gain and the mortality were followed up for 25 days. Results indicated a net increase of the weight gain and the feed intake. These showed that the formula made of fermented fish waste were similar to the control and some of them were higher than the control.
