Yak milk composition can vary with the age of the animal. Research has identified differences in protein, fat, and metabolite profiles between milk from younger and older yaks.
These findings provide insight into how biological factors such as age may influence the biochemical composition of milk. However, differences in composition do not necessarily indicate that milk from one age group is healthier than another.
The reported research examined compositional differences rather than demonstrating health benefits in humans. Further research would be needed to determine whether these differences have nutritional or functional significance.
