Metabolizable energy (ME) and metabolizable protein (MP) requirements of a dairy cow are influenced by production level, lactation number, body weight and breed. The following data provides a guideline for ME, MP Lysine and MP Methionine required by cows in various situations.
This e-book provides an in depth look at lysine and how this essential amino acid can help achieve maximum milk production to lower break-even costs and increase profit. A Closer Look: MP Lysine for Dairy Cattle helps readers understand how the variability in the quality of the byproducts and commodities often used to meet MP Lysine requirements, such as blood meal, can impact the amount of MP Lysine available to the animal, which affects the operation's bottom line. Additionally, it assists with comparing the characteristics necessary to effectively evaluate rumen protected lysine sources. These issues, and possible ways to deal with them, are all addressed in this e-book available for reading online or as a PDF download. Read the e-book, A Closer Look: MP Lysine for Dairy Cattle, and learn how variable your feed ingredients may be, some options for dealing with this variability and what impact they have on profitability.
Since 2015, Kemin has worked with customers to evaluate their blood meal supply. During this time, over 70 samples have been evaluated to determine the supply and cost of the MP Lysine contributed by blood meal.
Since 2015, Kemin has collected and tested over 70 blood meal samples from customers across the United States. The nitrogen (N) digestibility of those samples range from 21% to 97%. This means up to 79% of the nitrogen in the blood meal may not be digested by the animal and is simply excreted into the environment.
Blood meal is heated and dried while being processed. During this time, Maillard reactions occur, which bind sugars to amino groups, reducing the digestibility and availability of nitrogen or amino acids such as lysine. It is impossible to determine the extent of the damage without testing in the laboratory. See the proof.
Variation in the digestibility of the protein and amino acids contained in feed ingredients has a direct impact on production and profitability. One way to evaluate this impact is by determining the opportunity cost (the loss of potential profit) when feeding a poor quality, low digestibility, feed instead of good quality or highly digestible one. Learn more about the impact of variability on your profits.
USA Lysine® and MetiPEARL™ are manufactured to have a precise specific gravity and particle size leading to rapid transit through the rumen, reducing microbial exposure. The result is that these rumen protected amino acid (RPAA) products combine a high level of rumen escape and intestinal release, which results in bioavailability values that make them cost effective sources of MP Lysine and MP methionine. Review the results.
Two simultaneous studies were conducted to validate the bioavailability of USA Lysine®, a rumen protected lysine (RPL) product, in cattle. The data indicates that USA Lysine provides a high level of intestinally available lysine. Review the data and see for yourself.
Making a purchase decision in today’s economic climate requires an in-depth examination of a product’s features and benefits. From functionality to price, focusing on one or two characteristics doesn’t provide the complete picture - this is especially true when comparing rumen protected lysine products. Learn how to accurately compare rumen protected products.
Research indicates using USA Lysine® to increase MP Lysine supply improves diet formulation and milk component production. Review the research.
Blood meal is often used as a source of MP Lysine in lactating dairy diets and is relied upon to help meet the cow’s MP Lysine requirements. However, blood meal quality is highly inconsistent. Compare how the efficacy of USA Lysine® compares to blood meal as a source of MP Lysine and its impact on production.
Innovation in amino acid nutrition is changing how feed is formulated and dairy cows are fed, improving production and performance. Research shows achieving optimal production requires more than rumen escape. Read why bioavailable lysine provides a more efficient use of protein.
