Adult animals and poultry require eight essential amino acids for basic life functions: lysine, methionine, tryptophan, valine, phenylalanine, leucine, isoleucine, and threonine. During the growth phase, livestock and poultry need additional amino acids such as histidine and arginine to support healthy development. Young animals and birds also require glycine, cystine, and tyrosine to ensure proper growth and metabolic function. These amino acids play a crucial role in protein synthesis, muscle development, and overall health in farm animals. Lysine is one of the most important amino acids for improving protein utilization and enhancing meat quality in animals. It is naturally abundant in sources like soybean meal, fish meal, and meat meal, so feed formulated with these ingredients usually doesn’t suffer from lysine deficiency. However, crops like corn, cottonseed meal, and sesame cake have lower protein utilization rates. To compensate, lysine is often added to feeds such as barley and corn at concentrations of 0.2% to 0.3%, which can increase protein utilization from 50% to up to 80%. Approximately 90% of global lysine production comes from molasses-based fermentation processes. Methionine is widely used as a food and feed additive due to its ability to improve lean meat quality, boost egg and milk production, and enhance overall animal performance. It typically makes up 0.05% to 0.30% of feed formulations. Studies have shown that adding 0.5 kg of methionine to compound feed is equivalent to including 25 kg of fish meal. Methionine has been used in animal nutrition for over 20 years, with significant growth in the last decade. Globally, its production has increased by an average of 29% annually. In 1979, worldwide methionine production reached 150,000 metric tons, with France leading in output, followed by Germany, the U.S., the Soviet Union, Mexico, and Italy, all expanding their production capacities. The key to efficient methionine production lies in the availability of raw materials like acrolein and methyl mercaptan. A synthetic alternative, 2-tert-butyl-4,4-hydroxyanisole (MHA), can be used to replace methionine. MHA is absorbed by animals and converted into methionine through biochemical processes. One gram of methionine is approximately equivalent to 1.2 grams of MHA, making it a cost-effective substitute in some feed applications. Tryptophan plays a vital role in plasma protein renewal, riboflavin metabolism, and the synthesis of niacin and heme. A deficiency in tryptophan can lead to stunted growth, weight loss, and testicular atrophy in male animals. Due to its high production costs and limited economic returns, tryptophan is produced in smaller quantities, typically several hundred tons annually. It is mainly used as a supplement in artificial milk for piglets, with typical addition levels ranging from 0.02% to 0.05%. A small portion is also used in diets for sows and laying hens to support reproductive health and egg production. Silicon nitride ceramic materials can be used for high-temperature engineering components, advanced refractory materials in the metallurgical industry, corrosion-resistant parts and sealing parts in the chemical industry, and cutting tools and cutting tools in the machining industry.
