How Bypass Proteins Work

What is a dairy bypass protein?

Dairy Bypass Protein is an animal or plant-based protein source that resists degradation in the cow’s rumen in order to pass into the lower gastrointestinal tract and provide essential amino acids to the cow. By bypassing the rumen, more metabolizable protein is made available to help the cow meet her amino acid requirements for milk production and components. The more consistent a bypass protein source, the easier it is to balance the dairy ration for maximum milk production and feed efficiency. By feeding high-quality bypass protein, dairy producers can increase their metabolizable protein yield and reduce the amount of crude protein in the diet, thus reducing ammonia votalization and nitrogen excretion.

How bypass proteins work

As protein comes into the rumen, it is broken down into peptides and then further digested into amino acids. The amino acids available to ruminal microbes are utilized directly or deaminated to yield carbon skeletons and ammonia.

Particles of AminoMax products, however, are kept intact in the rumen and remain suspended in ruminal fluid until they are passed into the lower GI. This bypass method allows our products to deliver consistently high levels of bioavailable lysine, methionine and other essential amino acids to your dairy cattle, allowing your herd to produce more milk with higher milk components.

AminoMax products are plant-based bypass protein supplements designed to deliver an amino acid profile customized for lactating dairy cows. The blend combines canola meal and soybean meal, which both contain amino acids that have been shown in university research to stimulate milk production and milk quality.

Because the bypass amino acid requirements of dairy cattle are consistently met with AminoMax products, your nutritionist can reduce the amount of crude protein in the diet to maximize the use of forages and fermentable carbohydrates.
