The objective of this paper was to study the amino acid composition of donkey milk inhabiting the Kegety gorge of the Chui region. As well as human milk, donkey and mare’s milk is albumin; the amount of casein is 35-45%, while cow’s milk is casein milk with casein content over 75%. The peculiarity of albumin milk is a higher biological and nutritional value, due to better amino acid balance, high sugar content and the ability to form small, delicate flakes when souring. In terms of its properties, albumin milk is closest to human milk and is the best substitute for it. The obtained results showed that the quantitative content of 7 essential amino acids out of 8, such as lysine, phenylalanine, leucine, isoleucine, methionine, valine, threonine is relatively high compared to other amino acids. Despite the absence of tryptophan in donkey milk, the percentage of 8 essential amino acids in donkey milk protein exceeds that in mare and cow’s milk.
