Does a donkey produce milk for cheese?
A donkey will produce milk after giving birth to foal. However, to collect the milk to make cheese, the foal will need to be given commercial milk replacer as the donkey will likely not produce enough milk to support both the foal and the milk collection. Also, this could be a rather dangerous prospect as donkeys are not generally well trained to stand for milk collection by hand and there is no commercial equipment available to milk them out mechanically.
In general, in the United States cows are the primary species that is commercially milked to produce dairy product, with a much smaller secondary market for goat milk. In other countries, camels, water buffalos, and yaks are also milked.
