What is the difference between lysine sulfate and lysine hydrochloride

Lysine is an essential ingredient in feed, and how to choose an appropriate lysine product is very important for feed mills. Generally speaking, feed mills should choose appropriate products based on 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 hydrochloride products, the research data of sulfate products is less for the sensitivity requirements of animal species to impurities in amino acids and the tolerance of animals to sulfate. Therefore, 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 can be as high as 35%. Below 1.5%. Lysine sulfate products have a high content of magazines, which makes it more hygroscopic. 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 are more nutritious than hydrochloride products still lacks scientific basis. Lysine sulfate products are only equivalent to 65% of lysine hydrochloride products. So its proportion is relatively light. Lack of the space required by the formulator. In addition, the concentration of sulfate radicals 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 trough feed.
