What Is Structure of L-threonine?

Under the dual pressure of cost and environmental protection, feed additives have become a research hotspot in the field of animal nutrition since the 1990s. Many investigations and studies have found that using feed grade L-Threonine to replace part of the protein feed can improve the health of livestock and poultry and even improve feeding efficiency. The current L-Threonine crystal technology was originally derived from the study of its structural formula.

How can the structural formula of l-threonine be described?

The chemical formula of L-Threonine is C4H9NO3, and its appearance presents the characteristics of a white orthorhombic crystal system or crystalline powder. L-Threonine is not the same as lysine. It has no smell and tastes not bitter, instead, a little sweet, which will not affect the eating preference of livestock.

L-Threonine will only melt and break down when heated to 253°C, showing its stable properties; it is soluble in water at high temperature, and its solubility at 25°C is 20.5g/100ml. L-Threonine has an isoelectric point of PH 6.16 and is insoluble in ethanol, ether and chloroform.

At present, it is generally believed that the feed intake will subjoin with the addition of the added amount before the animal does not reach the optimal requirement of L-Threonine.

When the physiological requirement of feed grade L-Threonine is reached, the animal intake reaches the limit zone, and the production at this time the performance is the best; when the amount is beyond livestock body needs, the feed intake and daily increase quality will decrease instead.

What kind of research results did experts get on feed grade L-Threonine?

Threonine was discovered in fibrin hydrolysate in 1935. The first studies on threonine requirements were published in the 1960s and early 1970s. However, it was not until the 1980s that people had a breakthrough in the understanding of whose nutritional value, and a series of derivatives such as L-Threonine crystal were born.

To this day, L-Threonine has been proven to be a restriction for animal maintenance and growth. It has certain nutritional effects on poultry, livestock and fish in different growth stages and production purposes.

• L-Threonine can adjust the nutrient elements in the feed to balance it and promote the growth of livestock;

• Using L-Threonine can effectively improve the meat quality of livestock and increase the feed-to-meat ratio;

• It can improve the nutritional value of feed ingredients with low amino acid digestibility, and play an effect that exceeds the original feed;

• It can be used to produce low-protein feed, which helps to save the increasingly scarce protein resources, thus reducing the cost of feed ingredients;

• The use of L-Threonine feed additives meets the environmental protection requirements of modern animal husbandry, which can reduce the nitrogen content in livestock manure and urine, and the ammonia concentration and release rate in livestock and poultry houses.

What place does L-Threonine stand in structure of animal husbandry?

In the actual production of animal husbandry, due to the lack of feed grade L-Threonine in ordinary feed, it is necessary to increase the protein level of the feed to meet the needs of livestock for L-Threonine crystal, resulting in excessive amounts of other elements.

Without L-Threonine's participation in the balance, excess amino acids need to be produced into urea and excreted from the body, which consumes extra energy, resulting in waste of feed resources and environmental pollution. The excess protein also undergoes harmful fermentation in the large intestine, causing diarrhea and other problems in livestock.

The discussion of these issues and the conception of the new L-Threonine technology system have very important theoretical and practical significance for promoting the innovation and development of the entire animal nutrition discipline structure and technology system.

The theoretical basis of feed grade L-Threonine low protein diet is amino acid balance and ideal protein model. It is not lower than the actual demand for livestock, but to make the assessment of the demand from rough to precise.
