Soybean meal is the most common source of protein supply in industrial poultry farming, and other sources of protein are compared to soy. The amino acids in soy protein have a very high digestibility in all types of poultry of different ages. Poultry is very sensitive to the anti-nutritional factors of soy, and it is necessary that the full-fat soybean flake used is well processed and all its anti-nutritional substances have been neutralized. Full fat soy flake is a very good source of protein and energy, and its energy content is higher than soy flour due to the presence of fat. If full fat soy flake is used in sufficient quantity and in balance with other ration components, it will be a very high quality protein source and very valuable for energy supply and will have a significant effect in reducing the price of the ration and increasing the conversion factor. . In case of using full-fat soybean flakes, more amounts of vitamin E are considered in the diet.
Due to the high amount of unsaturated fatty acids in soybean oil, the consumption of soybean full fat flake in poultry diet is limited.
