Adult animals and poultry need eight amino acids for life support: lysine, methionine, tryptophan, valine, phenylalanine, leucine, isoleucine and threonine; livestock and poultry in growing season In order to ensure normal growth and development, in addition to the above essential amino acids, histidine and arginine are required; in addition to the above, young animals and young birds require glycine, cystine and tyrosine.
1 Lysine can improve protein utilization and meat quality in animals. The lysine content in bean cake, fish meal and flesh powder is rich. If used to mix feed, it generally does not feel lysine deficiency. Corn (2433, -3.00, -0.12%), cottonseed cake, and sesame oil cake are used as feed, and the protein utilization rate is low. When feeding pigs, chickens, etc., it is necessary to add an appropriate amount of lysine, usually in 0.2% to 0.3% lysine is added to barley and corn to increase the protein utilization rate from 50% to 70% to 80%. About 90% or more of lysine is produced by fermentation of molasses.
2 Methionine food and feed fortifiers, which have the effect of improving the quality of lean meat and increasing the rate of egg production and milk production, which accounts for 0.05% to 0.30% of the feed. The test results showed that adding 0.5 kg of methionine to the compound feed was equivalent to adding 25 kg of fish meal. Methionine has been used for more than 20 years and has grown more rapidly in the past 10 years. The annual growth rate of methionine production in the world is 29%. In 1979, the world's total production of methionine reached 150 kt, France's output ranked the highest in the world, followed by the Federal Republic of Germany, and the United States, the Soviet Union, Mexico and Italy also rushed to build new plants to expand their productivity.
The key to the development of methionine production lies in the production of the raw materials acrolein and methyl mercaptan. Industrially synthesized methionine analog with hydroxyl group 2-tert-butyl-4,4-hydroxyanisole (MHA) can replace methionine, and MHA absorbs amino-substituted hydroxy groups in animals to convert to methionine. 1.2 g of MHA is equivalent to 1 g of methionine.
3 Tryptophan can participate in the renewal of plasma proteins, promote the role of riboflavin, and contribute to the synthesis of niacin and heme. When livestock and poultry lack tryptophan, growth stagnates, weight loss, and testicular atrophy in male animals. Because of the high production cost and poor economic efficiency, tryptophan has an annual output of only several hundred tons. It is mainly used as an artificial milk additive for piglets, and the addition amount is 0.02% to 0.05%; a small part is used for the diet of sows and laying hens.
