The second is to remove the nipple. After birth, some calves have 1 ~ 2 nipples in addition to the normal 4 nipples. These extra nipples are called accessory nipples. It not only affects the appearance, but also causes bacterial infection and affects milking. The accessory nipple can be removed when the calf 1 ~ 2 months. The specific method is to disinfect the breast first, then cut off the accessory nipple from the base with sharp bending scissors, and disinfect the wound with 5% ~ 10% iodine tincture to prevent infection. Thirdly, we should provide enough drinking water. Because the water contained in milk can not meet the normal metabolic needs of calves, cows must drink enough water during lactation. At first, you can add 1/2 ~ 1/3 hot water to the milk, and at the same time, set a sink in the calf sports ground to let it drink freely. Fourth, we should strengthen exercise. Except in cold weather, calves are allowed to move freely on 10 day after birth, and should be properly driven after 4 ~ 6 weeks, and the daily exercise time should be no less than 1 hour to enhance their physique. Fifth, we should always clean up and observe. Calves have high requirements for living environment, so they should always clean their pens, change their mats frequently, and keep them clean, dry, warm, spacious and ventilated. When feeding calves, observe their appetite, exercise and spirit; Observe feces when sweeping the floor. Healthy calves are agile, with bright eyes and shiny fur, otherwise they may get sick. If the eye socket of the calf is sunken, the ears are drooping, the skin is tight and the feces are seriously polluted, it can be initially diagnosed as enteritis.
Sixth, be clean. Cattle feed and milk should not be moldy and frozen, and more importantly, it is necessary to prevent metal such as nails and fecal impurities from being mixed. Commercial feed must be within the shelf life. If you want to feed homemade feed now, you should get it ready now. When feeding artificially, the cows and feeding tools must be cleaned and kept clean after each use; Brush the calf 1 ~ 2 times a day to ensure that the calf is not polluted by sewage and feces and reduce the occurrence of diseases. Seventh, we should prevent licking addiction. Newborn calves had better line up. After each feeding, the residual milk at the mouth and nose of the calf should be wiped clean. For the calf that has formed licking addiction, a small wooden board can be placed in front of the bridge of the nose to correct it. In addition, feeding calves in a single circle also plays an important role in controlling the occurrence of colibacillosis and reducing the occurrence of umbilical cord inflammation. Eight must be strictly disinfected. To establish a regular disinfection system, winter 1 time, summer 2 ~ 3 times a month, to thoroughly disinfect the ground, walls, railings, food trough, etc. Use disinfectant thinner such as gold. If infectious diseases are found, the environment and utensils that the dead cattle come into contact with should be thoroughly disinfected. In the shed sprayed with golden fungus, the beneficial bacteria in the environment are greatly increased, which is helpful to prevent calves from getting sick, eliminate the odor of cowshed and improve the breeding environment.
