ABSTRACT
The objective of present study was to produce
poultry feed with a best quality using ternary mixture of industrial wastes: fish industry waste, sugar
industry waste (molasses) and yeast waste after 15 d biotransformation using
response surface methodology to design and analyze the experiment data. Changes in the nutritional
quality and biochemical properties viz., pH, dry matter, conductivity,
total organic carbon, total nitrogen, phosphorus, trimethylamine, protein, fat,
carbohydrate, histamine, aflatoxins and minerals were evaluated during a
biotransformation period of 15 d. The experimental findings revealed that the
formulation including 50% of fish waste, 12.5% of molasses and 37.50% of yeast
waste were found to be best quality poultry waste. It was characterized as
odorless, with a stable pH, rich in protein, fat and carbohydrate as well as no
alterations of bacteria and absence aflatoxins from the fifth day on ward. The
nutritional value of the developed poultry fees was studied on a population of
broiler chickens by incorporating with barley flour and eggshell. The product
possesses a better nutritional quality comparable to commercially feed.
