The impact of amino acids on LCIA

Published on 25-11-2022 - By Kemin

Our rumen-protected amino acids reduce LCIA on three levels; in the diet formulation itself due to better allocation of raw materials, by better feed efficiency reducing the impact per kilo of milk produced, and by better processing in the industry, reducing the GHG per kilo of cheese. 



The impact of amino acids

  • Thanks to a diet balanced for amino acids, we formulate concentrates and final dairy diets with less carbon footprint (CO2-eq). Thanks to implementing Methionine and Lysine we reduce or remove the use of certain feed ingredients with high LCA or decrease the supply of protein that the animal is not using or high-phosphorous ingredients. This reduction of the carbon footprint is due to a better allocation of raw materials (local ingredients with a lower carbon footprint) used in the formulation, and a higher N efficiency. This can only be possible if we formulate amino acids, without losing farm profitability.
  • Amino acid nutrition also provides flexibility in formulation when we are selecting or substituting different feed materials due to either price or availability. When you apply the precision feeding concept in your ruminant operations, the amount of total CO2-eq contribution is reduced. This is due to the reduced amount of CO2-eq per kilogram of dry matter supplied to the animal with a better allocation of available raw materials at less cost. The improvement in MP efficiency provides us an opportunity to formulate diets with lower CP content without compromising the yield of milk and milk components, reducing the total feed cost, or improving the Income Over Feed Cost (IOFC). By formulating with both rumen-protected Methionine and Lysine, P-Met, and RP-Lys, we improve N (8%) and P (2%) efficiency, reducing the CO2-eq per kilogram of dry matter intake (15%) and the excretion of N2O (7%) into the environment.
  • Thanks to our rumen-protected Amino Acids, we improve feed efficiency resulting in a translation of a 48 % reduction in methane emissions and 2,000 kg CO2-eq per cow per year, reducing the LCA per kilo of milk and meat. Instead of slightly overfeeding animals to ensure good growth or production, either in terms of amount or quality of feed, you focus on providing your livestock with exactly what they need. This reduces the demand for feed and feeds waste, which in turn allows those assets to be used to meet other needs, such as biofuel production or human food.
  • Implementing rumen-protected amino acids in the diet enhances cheese because of the increased casein production. Our research proves that we improve cheese efficiency by 8 kilos more cheese per tonne of milk collected, improving the cheese industry's profit (56 €), as well as reducing the LCIA per 100 kilos of cheese (62 kg CO2-eq).
