Is it safe to add l-threonine to feed?

No matter what kind of feed additives the farmers use, whether L-Threonine is imported or domestically produced, the key is ensuring health of the livestock in order to maximize production performance. If the L-Threonine crystal used is not safe, let alone increasing the production of meat, eggs, and milk, it will not even make the livestock reach their original level, even threaten their lives.

Does adding L-Threonine into feed produce adverse reactions?

When the primary restricted amino acids have been fully valued in compound feeds, L-Threonine, which has been ignored for a long time, has finally gradually become a key factor affecting animal performance and production costs. As the existence of synergistic or antagonistic relationship between various amino acids in the diet, threonine interacts with other amino acids in the feed as well.

l Threonine vs Lysine

If the feed lacks L-Threonine, it will affect the utilization of lysine. According to reliable experimental results, an appropriate ratio of lysine and threonine can improve the growth performance and lean meat yield of livestock.

l Threonine vs Tyrosine

Similarly, when there is an excess of lysine or methionine in the feed, the demand for L-Threonine increases, which is not difficult to understand. Adding an appropriate amount of threonine can alleviate the growth inhibition caused by excess other amino acids.

In particular, increasing the intake of feed grade L-Threonine can reduce the level of tyrosine in the plasma of broilers and reduce the damage to the eyes and paws caused by excessive tyrosine.

l Threonine vs Glutamic

In addition, L-Threonine can be converted into serine and glycine. Recent studies have found that adding glutamic acid to feed will reduce the degradation of threonine and affect the utilization of threonine. Therefore, farmers should take care to avoid the situation where both are used at the same time.


How to realize the safe addition of L-Threonine?

Adding an appropriate amount of L-Threonine to low-protein or L-Threonine-deficient livestock feed has obvious effects. Applicable groups include but are not limited to sheep, cows, eels, poultry and pigs.

However, the mechanism by which feed grade L-Threonine participates in the livestock body protein formation, impact on immune function, the mechanism of action in the process of antibody formation, the interaction and optimal balance with other essential amino acids, and requirements of L-Threonine on livestock at different growth stages as well as effective use of L-Threonine need to be further discussed.

Therefore, when adding L-Threonine, various factors should be considered comprehensively, including the factors that affect the utilization and the market price, so as to formulate efficient and economical feed.


What advice can farmers get on the safe use of L-Threonine?

The prepared L-Threonine mixed feed should not be stored for too long, and should be stored in a clean and dry warehouse to prevent moisture deterioration, mold production, and livestock poisoning.

Farmers must correctly dispense L-Threonine in different proportions according to different types of livestock and different growth and development stages. The energy feed must be added accurately, the mixing must be uniform, and it must not be used indiscriminately.

Many farmers who use L-Threonine often use their own experience to change the recommended formula at will, resulting in various nutritional indicators that cannot meet the growth needs of livestock and poultry at various stages. Do not mix the prepared L-Threonine feed with other types of feed to avoid affecting the effect.

The replacement of L-Threonine premix should be done step by step. If the premix is changed suddenly, the livestock will not adapt, which will affect the feeding and growth. In use, the amount of new L-Threonine crystal feed should be gradually increased, and the amount of old materials should be reduced. It takes about a week to transition to completely using the new premix.

L-Threonine premix should not be used directly. It should not be washed with boiling water or cooked to avoid damage to nutrients. It should be added to dry feed in small quantities and many times, and mixed until evenly dispersed.


As long as it is used properly, L-Threonine is your safest helper, and the scientific use of L-Threonine marks a big step forward in feed science to "precise nutrition". After you purchase L-Threonine from Polifar Group., we will provide you with considerate and meticulous services to help you better establish a feeding management system to increase your farming profits.
