The TMR mixer is a crucial piece of equipment for dairy farms implementing the total mixed ration (TMR) feeding technology for cows. It is an indispensable facility for constructing modern, standardized, digital, and large-scale dairy farms. The TMR mixer can automatically weigh and measure various rough and concentrated feeds, such as fresh and dried forage, crop straw, silage, etc., and directly chop, knead, and mix them. The use of TMR feeding technology for cow raising ensures that the cows consume a balanced diet with the appropriate ratio of concentrate to roughage, consistent nutrient concentrations, which is beneficial for enhancing the cows' productivity and prevents selective feeding and nutritional imbalances.
