1. Soybean meal is the most abundant and widely used of 12 animal and vegetable oil meal feed products. As a kind of high protein, soybean meal is the main raw material for making livestock feed, and can also be used for making pastry food, health food, cosmetics and antibiotics. The crude protein content of bean cake and soybean meal is as high as 30 ~ 50%, which is one of the main protein feeds for animals. However, untreated soybean cake and soybean meal contain antitrypsin, urease, saponins and goiter inducing factors, which will adversely affect the digestion and utilization of animals and feed. Rapeseed cake, cottonseed hull, soybean meal, etc. Detoxification and fermentation of feed starter are carried out to obtain feed.
2. About 85% of soybean meal is used to feed poultry and pigs, and various amino acids contained in soybean meal are suitable for the nutritional needs of poultry and pigs. Experiments show that the amino acids contained in soybean meal alone are enough to balance the nutrition of poultry and pigs without adding extra animal protein, thus promoting the nutrition absorption of livestock. Soybean meal has been used to the greatest extent in poultry and pig breeding. Only when the unit protein cost of cottonseed meal and peanut meal is much lower than that of soybean meal will they be considered for use. In fact, soybean meal has become the benchmark for comparison with other sources in protein.
3. Delicious and digestible soybean meal can increase milk yield in the process of dairy cattle feeding. Soybean meal is also one of the most important oilseed cakes in beef cattle breeding. Soybean meal is also used to make pet food. Simple mixed food of corn and soybean meal has the same value as food made of high animal protein. Soybean meal is also widely used in aquaculture. A variety of amino acids contained in soybean meal can completely meet the special needs of fish for amino acids.
