Why should L-isoleucine be added to the feed

L-Isoleucine is one of the essential amino acids, which plays an important role in the growth, development and reproduction of animals.

What impact will the lack of isoleucine in the diet have on livestock and poultry?

1. The lack of isoleucine in the feed will have a negative impact on the growth performance, carcass traits and muscle fat content of finishing pigs.

2. The lack of isoleucine in the feed will seriously affect the feed intake of breeders, resulting in weight loss and lower egg production performance.

3. The lack of isoleucine in the feed will reduce the blood sugar level of the cows and reduce the milk production of the cows.

Advantages of L-isoleucine

1. Animal nutrition

Isoleucine is one of the essential amino acids, which plays an important role in the growth and reproduction of animals.

Improve meat quality, increase milk and egg production.

Promote gluconeogenesis and enhance the immunity of animals.

2. Nitrogen reduction and emission reduction

Feed protein is reduced, feed is fully utilized, and fecal and urine nitrogen emissions are reduced.

3. Optimize feed structure

As dietary protein in coarse grains decreases, the use of isoleucine is required to formulate diets that more closely match the animal's amino acid requirements. (mainly pig and poultry feed)

4. Reduce feed cost

The addition of isoleucine reduces the content of soybean meal, the most expensive vegetable protein source in feed, and reduces feed cost.

Function of L-isoleucine

1. Improve animal growth performance

Isoleucine can promote the production performance of mid-growth grass carp. Improvement of yellow feather chicken muscle quality and muscle antioxidant capacity. Guarantee the growth function of ruminants.

2. Improve animal immunity

Dietary supplementation of isoleucine can improve the innate and adaptive immunity of weaned piglets by up-regulating the immune response mediated by PRRs.

3. Improve nitrogen conversion efficiency

Isoleucine can improve the conversion efficiency of dietary nitrogen and reduce the excretion of fecal nitrogen. And the low-protein diet supplemented with rumen Met+lle+Leu group can significantly increase ADG, improve blood glucose levels, and increase serum insulin levels.

4. Improve energy utilization

Isoleucine aids glucose uptake and energy utilization in the gut and muscle through the expression of glucose transporters in the gut and muscle.

Polifar Group Limited has L-isoleucine products specially used for animal feed, and the isoleucine content is ≥90%. Adding L-isoleucine as a nutritional supplement to low-protein diets can not only reduce the amount of high-value plant proteins such as soybean meal. Moreover, while ensuring the amino acid requirements of animals, it can also reduce fecal and urine nitrogen emissions and optimize feed efficiency and economy.
