This standard applies to the feeding, management and production of middle-class dairy herds and individual dairy cows in pasture circles, dairy farming communities, collective and individual dairy farms and dairy farmers in milk source bases in the agricultural and animal husbandry areas. Middle-produced dairy cows refer to herds and individual dairy cows with a milk production of about 5000kg~6000kgz for 305 days in a lactation period (milk production period) and a fat content of 3.5% (or equivalent fat content). Cows with low milk production (4000kg and above) can also be used.
