The protected lysine AjiPro-L®, an innovation in ruminant nutrition
AjiPro®-L proposes an innovative rumen protected lysine formula. Based on a technology resulting from more than 25 years of research and development, this solution combines an internal matrix, a layer of external protection and an emulsifying agent within a unique and patented formula. It ensures greater stability in the ration and rumen as well as optimal intestinal availability for ruminants. AjiPro®-L thus represents a major advantage in bovine nutrition, for which lysine is one of the essential and limiting amino acids.

AjiPro®-L, a solution adapted to the rumen of dairy cows
Dairy cows can use forages (grass, hay, corn silage, etc.) in order to transform them into dairy proteins. However, their conversion efficacy of these raw materials into milk remains weak (approximately 30%). In order to support optimal conversion, cow nutrition must provide a balanced intake in essential amino acids, and specifically lysine, rather than a certain protein level.
However, the free lysine used for monogastric animals (pigs, poultry), cannot be incorporated as is for ruminant nutrition since it is subjected to a strong natural breakdown process in the rumen and therefore not available for digestion in the intestine.
Resulting from more than 25 years of research and development in our labs in Japan and the United States, the protected lysine AjiPro®-L allows to alleviate this situation. This solution benefits from the unique dual protection of lysine. It is based on a lysine and fat matrix, doubled with a protective fat layer. The formula also incorporates an emulsifying agent in order to maximize the availability of lysine in the intestine.
This protection technology guarantees the product’s excellent stability both in the ration and rumen. Several independent studies have validated this essential characteristic. The bypass rate is more than 80%, the final intake of lysine can therefore reach the targeted levels.
The efficacy of AjiPro®-L has been demonstrated in multiple universities and research centers and is recognized by nutritionists. Today, AjiPro®-L is the leader in the North-American market, where the majority of dairy farms using protected lysine in their ration have chosen AjiPro®-L.
Dual protection ensures the product’s stability and high lysine digestibility.
Specifically for ruminants
AjiPro®-L does not interfere with the rumen’s natural fermentation process.
Decreasing the level of protein in the dairy cow’s ration reduces nitrogen excretion.
The need for importing lysine-rich ingredients, like soybean, is reduced.
Why do cows need protected lysine?
In order to optimize milk production, cows need lysine in a certain quantity as well as in a certain concentration compared to other amino acids coming from proteins in feedstuffs, such as soybean. A portion of these proteins breaks down in the rumen and is used to produce microbial proteins, which provides the intestine with 50 to 60% of the cow’s necessary amino acids.
The rest of the amino acids must therefore be directly provided by dietary proteins that are not broken down in the rumen (bypass protein) in order to provide amino acids directly absorbed by the intestine.
Unfortunately, no raw material is concentrated enough in bypass lysine in order to provide “just the right amount.” To cover the lysine and methionine requirements, the rations thus provide a surplus of proteins, resulting in an excess of numerous non-essential amino acids. This surplus is not used by the cow and is excreted in the urine and milk after transformations that are costly in energy for the cow. It is therefore of interest to use a source concentrated in lysine for an intake that precisely responds to needs rather than provide protein-rich sources in too large of quantities.
Consequently, researchers and nutritionists involved in bovine nutrition took interest in protected lysine. This amino acid positively influences the animal’s performance and specifically the volume of milk produced. Maximum responses in terms of milk volume are observed during the beginning of lactation.
AjiPro®-L, a product with proven quality
Created in accordance with European regulatory standards, our AjiPro®-L solution illustrates the specific attention to quality and safety of the Ajinomoto Group. Just like our research, fabrication and marketing procedures, our products benefit from a quality integrated management system, certified by the ISO 9001 standard.
Moreover, through the search for effective nutrition with limited environmental impact, we contribute to sustainable dairy farming.
The composition of AjiPro®-L in detail
Three major elements form the composition of the rumen protected lysine AjiPro®-L:
- L-Lysine monohydrochloride, the key amino acid
- Vegetal oil for ruminal protection
- Soy lecithin for intestinal digestibility
These ingredients are implemented within a specific and patented process, which ensures AjiPro®-L’s superiority compared to products using classic protection techniques.
