Chopped pilchard waste was mixed with 15% molasses and inoculated with a starter culture made of Lactobacillus plantarum. The silage was incubated at 22 degrees C for 20 days. Changes in the nutritional quality and biochemical properties (pH, dry matter, minerals, total and non-protein nitrogen, lipids and fiber) were monitored during a fermentation period of 15 days. The product obtained by fermentation was incorporated with bran and barley to make three formulas, which were then fed to broilers in four trials using five broilers each. The weight gain in broilers was recorded for 20 days. Results indicated that pH decreased considerably in the fermenting product and then remained constant at 4.2 and 4.5 in the two trials. Total nitrogen decreased slightly, whereas non-protein nitrogen increased significantly. The nutritional assays showed a net increase in the broiler weight relatively to the control diet. All the formulas made with the combinations of different proportions of ingredients resulted in similar growth of broilers compared with the commercial control-feed formula.
