Methionine, as the first limiting amino acid in feed additives, is of great importance to farmers. Currently, the global economic stagnation and rising prices of some raw materials have led to a shortage of methionine, causing its price to rise. This is especially true for large-scale, standardized farms, where the demand for methionine is even higher. To avoid waste and efficiently utilize feed-grade methionine, it is essential to choose higher-quality methionine suppliers. This article will focus on the scientific use of methionine in feed, its differentiated value, market functions, and future development trends, ensuring everyone understands the scientific application and market value of methionine in feed.
Methionine needs to be added to feed rationally; too much or too little will lead to increased costs and waste, as well as harm to animals. Insufficient methionine will result in nutritional imbalances and reduced product quality. Therefore, when choosing a feed additive supplier, one should choose a qualified, certified supplier or manufacturer with years of experience in the market. Polifar can continuously provide you with high-quality products, offering one-stop purchasing, saving you time, and helping you determine precise formulations. Experienced suppliers determine the appropriate methionine dosage based on animal breed, age, physiological stage, and feed formulation to avoid deficiency or excess.
Methionine deficiency can lead to slow growth, emaciation, increased diarrhea, weakened immunity, decreased egg/lactation production, and poor meat quality. Excess methionine, on the other
hand, increases the metabolic burden on the animal's liver, resulting in nutrient waste, increased costs, and higher nitrogen emissions, which is detrimental to environmental protection requirements in animal husbandry.
Currently, there are four main types of methionine used as feed additives: DL-methionine, hydroxymethionine analogues, rumen-protected methionine, and chelated methionine. Most livestock and poultry compound feeds generally choose L-methionine due to its high cost-effectiveness and rapid absorption. If high-temperature pelleting is required in feed production, hydroxymethionine is chosen; this type of methionine is suitable for high-temperature processing, exhibits strong stability, and retains its original properties even when heated. Ruminants typically use rumen-protected methionine to improve small intestinal absorption. Chelated methionine is commonly used in high-end sows, breeding poultry, and aquatic feeds. This feed-grade methionine combines the functions of both amino acids and minerals, resulting in better effects.
The key to the scientific application of methionine is to determine the optimal ratio based on lysine, achieving a balance of amino acids. This reduces crude protein while maximizing growth efficiency and minimizing breeding costs.
DL-Methionine is the starting amino acid for protein synthesis; without it, the protein synthesis process cannot begin. Therefore, it is particularly important in animals. Feed additive methionine directly determines the rate of muscle, viscera, organs, feathers, and tissue development, making it an essential nutrient for growth and development.
Adding methionine to feed can increase glutathione levels in animals, effectively strengthening the body's antioxidant capacity. It also promotes the proliferation of immune cells and the generation of antibodies. This helps maintain stability during periods of high temperature, or under stress such as regrouping, disease prevention, or feed changes, significantly reducing morbidity and mortality.
DL-methionine provides methyl groups, promoting choline and carnitine synthesis, effectively accelerating fat transport and oxidative decomposition, reducing liver fat deposition, preventing metabolic diseases such as fatty liver and ascites, and making animals healthier.

Adding methionine feed additives to specialized breeding chickens, pigs, and dairy cows can directly affect ovulation count, fertilization rate, embryonic development, and lactation capacity. With balanced nutrition, it can prolong the peak reproductive period, improve offspring survival rate, and enhance overall farming efficiency.
Broilers fed with well-formulated methionine feed can effectively shorten their growth cycle and reach market weight quickly. Furthermore, the meat after market weight is plump and has a low lean meat and abdominal fat percentage. During the farming process, a lower feed conversion ratio results in more uniform weight after market weight and higher slaughter profits.
Laying hens require sufficient nutrition for continuous egg production and have a sustained need for DL-methionine. Sufficient methionine in daily feed, combined with other nutrients, can increase egg production rate, prolong peak production, increase egg weight, strengthen eggshells, reduce broken and substandard eggs, and directly improve profitability.
Appropriately added methionine can repair the fragile intestines and high stress levels in weaned piglets, preventing weakened immunity, excessive diarrhea, and weight loss after weaning, laying a nutritional foundation for later growth and fattening.
The dosage of methionine in feed needs to be adjusted at different stages of animal growth. If you have any questions, consult relevant suppliers or manufacturers. In the fattening stage of pigs, the ultimate goal of adding methionine is to optimize protein deposition, improve meat quality, and reduce the feed conversion ratio. Even with a low-protein formula, faster growth can be achieved, reducing soybean meal usage and lowering the cost per ton of feed.
Adding rumen-protected methionine to dairy cows can improve milk protein and fat content, increase milk production, alleviate metabolic burden, reduce the risk of ketosis and fatty liver, and extend the lifespan of dairy cows. This increases the actual economic benefits of dairy farms.
In aquatic animals such as fish, shrimp, and crabs, to avoid high mortality rates due to excessive stocking density, the rational addition of chelated methionine to feed can enrich the meat quality, enhance stress resistance, improve the quality of aquatic products, and increase the value of other nutrients.
With the current global economic slowdown, escalating conflicts in some regions, and frequent price fluctuations in soybean meal and corn, the price of methionine has been rising continuously due to the complex situation, changing daily. Due to its irreplaceable role in feed, companies currently need to weigh all factors and rationally purchase methionine based on demand.
Currently, as a major contributor to the global economy, China is vigorously promoting low-protein diet technology, which requires the continuous support of methionine. Adding methionine to feed can reduce the use of protein raw materials, thereby reducing costs and nitrogen emissions, and realizing the development direction of green and environmentally friendly aquaculture.
When factories or suppliers possess more precise formulation and application technologies, or when feed companies continuously optimize their formulas through years of practice and utilize precise methionine application technology, they can effectively reduce overall feed costs, giving them a significant competitive advantage in the market.
99% DL-Methionine plays a crucial role in animal nutrition and is a highly concentrated bulk raw material, historically reliant on imports. With advancements in Chinese technology, domestic production capacity has expanded, significantly improving supply stability and providing a solid guarantee for the security of the domestic aquaculture industry. Furthermore, China possesses the strength to continuously provide high-quality products to foreign countries.
The methionine industry will continue to develop in the future, moving towards high efficiency, stability, green practices, and precision. High global demand for meat products will place higher demands on livestock farming worldwide, requiring farms to consistently produce high-quality meat. China will supply the world with superior liquid methionine, rumen-coated methionine, and microencapsulated methionine, catering to a wider range of farmers.
Low-protein diets, precision nutrition, and digitally-based formulations are driving more scientific and rational methionine addition. China's domestic methionine production capacity continues to increase, breaking the international monopoly and contributing to more stable global prices. Furthermore, methionine can be synergistically used with other amino acids such as lysine, threonine, and tryptophan, becoming a standard component of high-efficiency farming.
We can see that 99% methionine has enormous potential for future development, with more stable products, more precise applications, more diverse sources, and a more integrated industrial chain.
Feed-grade methionine is a core nutrient, cost regulator, quality enhancer, and health guarantor in modern animal husbandry. Methionine is integrated throughout the entire process of feed research, production, and application, influencing animal growth, immunity, reproduction, and the entire production cycle, connecting feed companies, farms, traders, and consumers across the entire industry chain.
