Kemin would like to offer additional video resources to help explain why a rumen protected lysine like USA Lysine® is a great addition to dairy cow diets.
USA Lysine bioavailability values are supported by numerous in vitro evaluations and multiple in vivo dose response trials, which are widely regarded as the most accurate way to evaluate bioavailability. These trials, designed by Kemin, confirm the product efficacy. Watch the video below to learn more about the trials.
The state of the art technology used to manufacture USA Lysine delivers a product with the ideal particle size and specific gravity. These are the two factors impacting rumen retention time. Watch the video below to learn more on how these two characteristics combine to result in the most concentrated source of MP Lysine available.
It's common for producers to use blood meal as a lysine source in dairy cow nutrition. However, when blood meal is dried too aggressively it will prompt a Maillard reaction, which is an ongoing process that happens when amino acids bond with sugars during heating. The result is the amino acid can no longer be absorbed by the animal and is simply excreted into the environment. See how these reactions make lysine unavailable to the dairy cow by watching the video below.
As shown in the video above, a Maillard reaction can negatively impact the amount of MP Lysine available to dairy cows. The question is: how variable is it? Oftentimes, computer software can't estimate the variability factors accurately enough for producers to know for sure if they are meeting MP Lysine requirements. That's why USA Lysine is a more cost-effective alternative for dairy cow balanced nutrition.
Reducing your reliance on blood meal as the primary source of MP Lysine creates a variety of opportunities in terms of space in a dairy cow's diet. Watch the video below to learn more.
Using a rumen protected lysine product not only helps reduce the variability, it can create additional opportunities to supply more nutrients within the ration. It takes 23 grams of USA Lysine to supply the same amount of MP Lysine as 0.5 lbs of high-quality blood meal. That leaves a lot of room for improvements. USA Lysine is a rumen protected lysine source to provide dairy cows with a consistent, concentrated and cost-effective supply of MP Lysine.
Using a rumen protected lysine product in dairy cow diets to increase production, improve efficiency or reduce crude protein levels requires confidence in the bioavailability value of the product. Multiple methods have been developed to evaluate bioavailability including in vitro, in situ or in vivo methods, which vary in complexity, expense and labor.
During in vitro studies, various bag types are used; therefore, the pore size of the bags and particle size of the materials tested must be assessed. If the pore size of the bag is larger than the particle size of the material being assessed, the material could escape from the bag, leading to biased conclusions. Watch the video below to learn more.
For more than 30 years, Kemin has invested in technology that’s revolutionized encapsulation, improving the way animal nutrition products are manufactured. Technology is only as effective as the people who build it. The Kemin team includes pioneers in encapsulation and highly trained experts who create the best products, which bring the best value for our customers. The combination of commercial feeding experience, in vitro and in vivo studies, on-farm data and quality control testing is unmatched. The result is a consistent, concentrated and cost-effective source of MP Lysine. Take a closer look at our proprietary GEM and MicroPEARLS® technologies by watching the following video.
Kemin has a commitment to the highest standards of testing. By continuously investing and maintaining top-of-the-line manufacturing facilities, Kemin ensures the quality of all ingredients used in their products. In 2013, Kemin chose to further formalize the company's commitment to quality by pursuing Global Food Safety Initiative (GFSI) benchmarked certifications. These are quality certifications identified by GFSI as meeting food safety standards worldwide.
