Soybean cake contains 42% of crude protein. Except for a slight deficiency of methionine, the content of other essential amino acids is relatively balanced, especially the lysine content is as high as 2.38%. Driven by profits, some self-employed households use low-temperature oil extraction to produce soybean cake. This kind of raw soybean cake contains anti-nutritional substances and it can be used directly to feed geese. Among them, 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 is reduced; the hemagglutinin can be changed under the action of certain microorganisms in the digestive tract Toxins reduce the growth rate of goslings; anti-vitamins: The raw soy cake contains anti-vitamin A, D and vitamin B12 factors that can cause deficiency of these vitamins. Therefore, raw soybean cakes can not be directly used as raw materials to feed goose, but can be heated to above 100°C to destroy toxic substances and eliminate adverse effects.
