Difference between L-Lysine HCL & L-Lysine Sulphate feed grade

Lysine is an essential ingredient in animal feed.

How to choose an appropriate lysine du product is very important for feed factories. Generally speaking, feed mills should choose appropriate products according to production conditions. Consider the various effects of lysine products on feed.

For example, the type of feed and the source of raw materials. Stability requirements of feed. Compared with lysine hydrochloride, the research data of lysine sulfate is less for the sensitivity requirements of animal species to impurities in amino acids and the tolerance of animals to sulfate radicals, so feed formulators are choosing to use sulfate products. At the time, we must be more cautious.

The main ingredients of both are lysine, but the two are completely different products. Since the lysine sulfate product has not undergone a purification process, it contains more impurities. The lysine hydrochloride content of the lysine sulfate product is 65%, and the content of the lysine hydrochloride product is as high as 98.5% or more, so the impurity content of the former can be as high as 35%, and the impurity content of the latter is Below 1.5%. 

Lysine sulfate products have a high content of magazines, which leads to serious moisture absorption. Severe moisture absorption may cause agglomeration of feed, oxidation of feed ingredients and mold growth. Due to the high content of impurities, it may also cause more diarrhea in animals.

Sulfate products contain trace amounts of other amino acids, but the role of these amino acids in animal nutrition is negligible. Sulfate products contain a large number of unknown ingredients. Its role has not yet been systematically studied. 

Therefore, the view that only these trace amounts of amino acids are used to explain that sulfate products have more nutritional value than hydrochloride products lacks scientific basis. Lysine sulfate products are only equivalent to 65% of lysine hydrochloride products. So its proportion is relatively light. Lack of space required by formulators.

In addition, the concentration of sulfate contained in sulfate products is too high, which can easily cause agglomeration of feed. In order to ensure feed quality, it is generally not recommended to use lysine sulfate products in concentrates and premixes. Because lysine sulfate products contain a large amount of magazines and sulfate, it is easy to aggravate diarrhea in young animals. Therefore, it is generally not recommended to use sulfate products in suckling pig feed and teaching feed.
