Winter warm water, cattle water quantity by dry matter intake, climate condition, the diet composition and the effects of physical activity. Dry milk cows to drink every day 70 jin, nissan 30 jins of cow milk to drink every day 100 jins, nissan 80 catties of cow milk to drink every day 200 catties. Cows normal body temperature is 38.5-39 ℃, water temperature in the winter and spring were in 10-19 ℃, can satisfy the cow required to produce the largest amount of drinking water, reduce the cow body stress reaction, reduce feed consumption, increase milk production performance.

Xia Changshui, moisture content in milk (86-89) %, protein, fat, lactose, minerals and vitamins (11-14) %. Burning hot summer, cow required water quantity is more than the spring and autumn and winter season, every adult cows dry matter of 1 kg to 3 kg of drinking water, every production of 1 kg milk to drink 3-4 jins. Plenty of free water, contribute to the normal synthesis of milk, can lower body temperature, reduce diseases triggered by the climate is hot in summer, also for clean drinking water to reduce the cow body gastrointestinal disease. Zap, therefore, in order to meet the water demand of cows, are inside a shelter or playground set up automatic water dispenser.

Water temperature, the temperature is higher than adult cattle calf, so the water temperature should be higher than adult cattle, general water with 35 ℃ ~ 38 ℃ advisable. Drink milk temperature: artificial feeding, calf in heating should be disinfected after cooling to 35 ℃ ~ 37 ℃ when feeding, high or low has bad influence.

Lactation cows drinking water temperature, the average water temperature, cold water for cooling factor, cows drink cold water consumption body heat, affect milk production, such as drinking less than 8 ℃ water, milk production is decreased obviously. Winter water temperature to maintain the cow in 9 ℃ ~ 15 ℃, drinks than 0 ℃ ~ 2 ℃ water cows produce more milk every day 0.57 litres, namely ChanNaiLv 8.7%. Drink gruel temperature: winter cows feed around 38 ℃ hot porridge, can enhance the cold resistance ability, improve ChanNaiLv 10%. Drinking water temperature: wheat bran cows postpartum due to lose a lot of water and thirsty, and low temperature. At this time drink bran instead of drinking water, the water temperature is higher than 1 ℃ ~ 2 ℃ temperature, have the action of complement humoral, warm the body
