Temperature requirements for cows in winter and spring
Drinking Temperature Temperature of lactating dairy cows Drinking temperature: The drinking temperature of dairy cows in winter and spring should be maintained at 9°C~15°C. In winter, cows should be fed a hot porridge with a temperature of about 38°C to increase their cold resistance and increase their milk production rate by 10%. At this time, use bran water instead of clear water to allow cows to drink. The temperature is higher than the body temperature of 1 °C ~ 2 °C, there is the effect of supplementing body fluids and warming the body. Do not drink cold water. Yak drinking temperature: calf body temperature is higher than that of adult cattle, so drinking water temperature should be higher than that of adult cattle, the general drinking water temperature is appropriate 35 °C ~ 38 °C. When calves are nursing, both the colostrum and the normal milk should be fed after cooling to 36°C after heating and sterilizing. High or low calves have adverse effects on calves. The temperature of the breast water should be scrubbed. Before the milking of the cows, the dry towels should be soaked in warm water of 45°C~50°C, and the breasts and nipples should be thoroughly scrubbed, then the breasts should be massaged for 1~2 minutes, and the breasts should be inflated and the nipples should be expanded. The milking began only when the venous engorgement and relaxation of the trophy of the breast were relaxed. Do not scrub the nipples with hot or cold water, otherwise the cows will feel uncomfortable and will have a suppressive reaction to the “milk†reflexes, which will reduce the milk production. Storage and disinfection of milk temperature of milk preservation: the new extruded milk, the temperature is close to the bovine body temperature, is a breeding ground for microorganisms, if you do not cool the temperature soon will be rancid deterioration, so immediately use the cold water soaking container for cooling, The temperature of the milk drops to 4°C to 10°C. Milk disinfection: milk contains a variety of harmful microorganisms, if not sterilized, these harmful microorganisms multiply, making milk rancid deterioration. Disinfection mainly adopts heat sterilization method. In order to prevent non-high-temperature nutrient substances such as amino acids and vitamins from being damaged in milk, milk disinfection is mainly carried out by “non-high temperature†heating and disinfection methods, namely pasteurization. Method: Heat the milk to 80°C for 15 to 30 seconds and stop heating immediately. The storage temperature of bovine semen is not afraid of cold due to heat, and the sperm can be deactivated at 54.5°C. On the contrary, low temperature can stop its movement, reduce energy consumption, and enable long-term survival. With liquid nitrogen at a temperature of -196°C, semen can be preserved for decades without deterioration. The rate of conception is about the same as that of fresh semen. This method has been widely used in the cattle industry. Preheating Temperature of Cattle Frozen Semen During artificial insemination of dairy cows, the frozen semen needs to be thawed, and thawing requires warm water. The temperature of the water should be accurately controlled at 41° C. to 50° C. to ensure that the thawing sperm motility is not affected and will not be affected. Improper temperature reduces fertility.
