In China, either small farmers bring their cows to the station or the cows are housed near the milking facility – to allow cows managed by households to be milked by machine and have the milk go directly to a refrigerated bulk tank. There are also a growing number of medium-sized specialized household farms with 200-10004 cows. These are often private farmers within reasonable transportation distances from major consuming areas. These farmers also have mechanized milking, cold storage, and highly productive animals (5000-7000 litres/head/year). Hand milking and un-refrigerated milk collection continues, but less and less of the resulting milk.
