L-threonine Supply Price,relationship with the growth performance of animals

L-threonine is an essential amino acid in animals and plays a crucial role in maintaining normal physiological functions and promoting the growth and development of animals. The following is a detailed elaboration of its relationship with animal growth performance:

Participation in Protein Synthesis

Protein serves as the material basis for animal growth. As one of the basic units constituting proteins, L-threonine directly participates in the synthesis of proteins in animals. When the supply of L-threonine in the feed is insufficient, the rate of protein synthesis in animals will slow down, thus affecting the growth rate and growth performance of animals. For example, in pig farming, studies have found that an appropriate level of L-threonine can significantly increase the daily weight gain and feed conversion rate of pigs and promote the deposition of muscle protein. This is because an adequate supply of L-threonine provides the raw materials for muscle protein synthesis, enabling pigs to grow and develop better.

Regulation of Immune Function

L-threonine plays an important role in regulating the immune function of animals. It can promote the synthesis of immunoglobulins, enhancing the immunity and resistance of the animal body. When animals are affected by diseases or stress factors, the immune system is activated, and at this time, the demand for L-threonine in animals increases. If the supply of L-threonine is insufficient, the immune function of animals will be inhibited, making them more susceptible to diseases, which in turn affects their growth performance. For instance, the appropriate addition of L-threonine in chicken farming can increase the content of immunoglobulins in chicken serum, enhance the resistance of chickens to pathogens, reduce the occurrence of diseases, and ensure the normal growth of chickens.

Influence on Amino Acid Balance

Animals have a certain proportional relationship in their demand for various amino acids. The balance between L-threonine and other amino acids is crucial for animal growth performance. When the content of L-threonine is not in balance with other amino acids, it will affect the absorption and utilization of other amino acids by animals. For example, in ruminants, the ratio of L-threonine to amino acids such as methionine and lysine will affect the growth of rumen microorganisms and the synthesis of proteins, thereby influencing the digestion and absorption of nutrients in the feed by animals and ultimately affecting the growth performance of animals. Therefore, reasonably adjusting the ratio of L-threonine to other amino acids in the feed can improve the utilization rate of feed protein by animals and promote animal growth.

Increase in Feed Intake

L-threonine also has a certain impact on the feed intake of animals. The appropriate use of L-threonine can improve the palatability of the feed, stimulate the appetite of animals, and thus increase the feed intake of animals. When the feed intake of animals increases, they can ingest more nutrients, providing sufficient energy and nutrients for growth, which helps to improve growth performance. For example, in aquaculture, adding an appropriate level of L-threonine to the feed can increase the feeding enthusiasm of fish, increase their feed intake, and promote the growth of fish.

In conclusion, L-threonine is closely related to the growth performance of animals. A reasonable supply of L-threonine is of great significance for increasing the growth rate, feed conversion rate, immunity, and feed intake of animals. In animal breeding and production, the addition amount of L-threonine in the feed should be reasonably adjusted according to factors such as the type of animals, growth stage, and production objectives, so as to give full play to the growth potential of animals and improve breeding efficiency.
