What becomes indispensable for domestic yaks when year-round intensive grazing is impossible?

Answer

Hay, such as timothy or orchard grass

In scenarios where the environment does not permit continuous, year-round grazing, harvested forages are required to bridge the nutritional gap and form the backbone of the feeding program. Hay, specifically good quality grass hay such as timothy or orchard grass, is utilized to constitute the bulk of the diet under these conditions. While yaks can tolerate coarser feeds, hay serves as the primary roughage replacement when fresh pasture is unavailable.
