The raw soybean cake contains anti-nutrients and it can be used directly to feed geese. Among them are: Anti-trypsin: can reduce the protein digestion and absorption rate of feed, reduce the feed conversion rate, so that the growth of the goslings is slow, the egg production of the goose decreases. 2. Haemagglutinin: It can become a toxin under the action of certain microorganisms in the digestive tract, which reduces the growth rate of goslings. 3. Anti-Vitamins: The raw soybean cake contains anti-VA, VD, VB12 factors that can cause deficiency of these vitamins. In view of the above shortcomings, raw soybean cakes can not be directly used as feed ingredients to feed goose. They can be heated to above 100°C to destroy toxic substances and eliminate adverse effects. China Agricultural Network Editor
