The hot and cold head method fixes the hot water bottle between the two corners of the cow and fills it with hot water in winter to make the cow feel comfortable. The cold and heat stress is small and the milk production is increased. The trimming of the hoof hoof method trims hoof hoofs once a quarter, especially in early spring.
