Also, this species is not costly to produce one liter of milk with a fat content of more than 4% of food goes to just 900 grams, if the fat content of milk is lower, the feed should be 780-800 grams.
Dilute these types more in the northern regions, with a cool climate. This is often the regions of Russia. Most are in Finland and North America.
