ABSTRACT

Chopped pilchard wastes were mixed with 15 % molasses and  inoculated with a starter culture made of Lactobacillus plantarum. The silage was incubated at 22°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 then fed to broilers in 4 trials using 5 broilers each. The weight gain in the broilers was followed for 20 days. Results indicated that the pH, decreased considerably and then remained constant at 4.2 and 4.5 in the two trials. The total nitrogen decreased slightly while the nonprotein nitrogen increased significantly. The nutritional assays showed a net increase in the broiler weight relatively to the control diet. All the formula made with the combinations of  different proportions of ingredients resulted in similar growth of the broilers compared with the commercial control-feed formula.
