Amino acid nutrition has crucial functions in metabolism with a noteworthy influence on animal health, fertility and oxidative and inflammatory status. It can help dairy animals overcome challenges and stresses throughout the complete lactation period, including the transition phase.
Increasing the available AA by supplementing diets with rumen-protected Met and Lys tends to positively increase milk volume and influences the production of milk protein and қ-casein. Both the farmer and the dairy industry involved in cheese processing, can benefit from AA balancing as қ-casein is the key component for cheese yield. It does not only improve the N efficiency by the animal, but also the dairy industry efficiency.
One strategy to increase the incomes in the farm management is by improving the nutritional efficiency. And, amino acid (AA) nutrition in dairy cows, continues to be more widely accepted to enhance milk protein production and to improve feed utilisation.
The efficiency of nitrogen (N) use on European farms is low. Only around 30% of the N consumed goes to the milk and this causes multiple problems like:
Kemin Industries launched the “Kemin Reference Manual for Ruminant Amino Acid Formulation” as part of its ongoing Lifelong Learning program. Written by experienced professionals and industry experts for nutritionists and technicians in the dairy market, the book focuses on how to formulate in different contexts and ruminant amino acid nutrition systems. Beyond formulation, the book inspires a new way to think about increasing revenue and profitability in dairy farming.
Feed formulation based on amino acids has been customary in other species for a long time. Therefore, it is the next logical step towards meeting more precisely the protein needs of ruminants. When attention is given to the concentration of metabolisable Lys and Met with respect to the total metabolisable protein, we can provide formulations and rations with a better cost-benefit relationship, which will also provide more efficient and more predictable results. This manual provides an opportunity to learn about different techniques, approaches and strategies in the nutritional management of dairy farms, to minimise the negative impact of unpredictable market fluctuations, as well as to keep the herds productive for the future.
