Cowhouse temperature The most suitable temperature for dairy cows is 12°C～14°C. The most suitable temperature for pregnant cows and lactating dairy cows is 16°C～20°C. When the cowhouse temperature of lactating dairy cows is higher than 24°C or lower than -4°C, the milk yield decreases. The optimum temperature for calves is 35°C to 38°C. 2. Drinking temperature (1) Milking cows Drinking temperature: 1 Ordinary drinking water temperature: Spring cow drinking water temperature maintained at 9 °C ~ 15 °C, compared to drinking -2 °C water cows daily milk production 0.57 liters, that increase the milk production rate of 8.7% . 2 Drink wheat bran water temperature: The dairy cow feels thirsty and loses body temperature due to loss of a lot of water after birth. At this time drink bran water instead of drinking water, the temperature is higher than the body temperature of 1 °C ~ 2 °C) cows normal body temperature 37.5 °C ~ 39.5 °C), there is added body fluids, the effect of warming the body. Do not drink cold water. (2) Yak drinking temperature: 1 general drinking temperature: calf body temperature is higher than adult cattle, so drinking water temperature should be higher than that of adult cattle, general drinking water to 35 °C ~ 38 °C is appropriate. 2 calf milk temperature: When calf artificial breast feeding, regardless of colostrum or regular milk, should be cooled after heating and disinfection to 35 °C ~ 37 °C feeding, high or low have adverse effects. In addition, the production of "small white beef" requires the use of breast-feeding male calves that are not emaciated. From birth to 100 days of age, it is completely dependent on milk for nutrition. The milk temperature must be controlled within the range of 40°C to 41°C, and the temperature should be maintained at 18°C. ~20°C. 3. Scrub breast water temperature Before each milking of the cow, it is necessary to use a dry towel to soak in warm water of 45°C to 50°C, scrub the breast and nipple thoroughly and then massage the breast. After 1 to 2 minutes, the breasts swell, the nipples swell, the milk veins bulge, and the breast splanchnic muscles relax. The reflexes that have produced a "milk" have begun and the milking can begin immediately. Do not scrub the nipples with hot or cold water, otherwise the cows will feel uncomfortable and will have a suppressive response to “milk†reflexes, ie, reduce milk production. 4. Temperature of storage and disinfection of milk (1) Storage of milk: Newly-extruded milk should immediately be cooled by immersing the container in cold water, and the temperature of the milk should be reduced to 4°C to 10°C. (2) Milk disinfection: milk disinfection is mainly used "non-high temperature" heating and sterilizing method, that is pasteurization method, the practice is: the milk is heated to 75 °C ~ 80 °C, keep 15 to 30 seconds, immediately stop heating. 5. Storage temperature of bovine semen With liquid nitrogen, the temperature is -196 °C. Its conception rate is similar to that of fresh semen, and this method has been widely used in the cattle industry. 6. Preheating temperature of bovine frozen semen Frozen thawed thawed, the temperature required to use warm water should be controlled at 41 °C ~ 50 °C, the temperature difference between above and below no more than 10 °C. In experiments with yellow cattle, thawing of frozen semen at a temperature of 41°C is thawing at a temperature of 38°C, which can increase the rate of female birthing by 33.3%.
