Low protein rations for dairy cattle: can intestinal digestible amino acids help?

Dairy farming is regularly in the spotlight as a result of the current nitrogen impasse in the Netherlands. A mandatory protein decrease is the feed discussion of the day in the Netherlands. The announcement of possible protein measures for the compound feed industry–in particular a maximum protein content in purchased concentrates and raw materials–is causing significant concerns for the sector. One of the possible ways to maintain cows' milk production and health with less crude protein is to formulate rations based on ileal digestible amino acids. For rations with a standard to high protein content (>16%), it was not necessary to take this into account until now.  In the event of a mandatory drop in crude protein, however, nutritionists will also have to keep an eye on sufficient ileal digestible amino acids in the ration. In most rations, methionine is the most limiting amino acid.

Amino acids are essential nutrients. They are the building blocks for protein synthesis, which means they are essential for cows' maintenance needs (immunity, metabolism ...) and the production of milk protein. There are 20 different amino acids in total, eight of which are essential and must, therefore, be sufficiently supplied through the feed because they cannot be produced by the animal itself: lysine, methionine, threonine, isoleucine, phenylalanine, leucine, histidine and valine. When a shortage of at least one specific amino acid arises, it limits growth, milk production and maintenance.
