What kind of special care should pregnant cows and calves do in cold wave and blizzard weather?

(1) Special care for pregnant cows. Cows should pay attention to two points in winter: First, meet the nutritional needs of pregnant cows, especially ensure the supply of protein, minerals and vitamins, and prevent cows from eating rotten or frozen feed; The second is to carry out refined management, and it is strictly forbidden to scare, slide and bump. (2) Nursing care of calves. Due to improper heat preservation measures, calves are prone to complications such as colds, indigestion and diarrhea, and serious cases lead to death. It is suggested that calves should be kept in a house with walls on all sides, and the house should have heating facilities. After the calf is born, dry it with dry sawdust or dry cloth, and then put it by the fire to dry its fur slowly. It is best to use double-layer padding for the calf circle, that is, dry sawdust is used to absorb moisture at the bottom, and dry wheat straw and straw are used to keep warm at the top. Change mats frequently, remove feces in time, and prohibit drinking and feeding frozen milk and forage.

(3) It is necessary to do a good job of cold protection for cows in labor, primiparity and poor health. The breasts of parturient and primiparous cows are basically in edema state. At this time, the nipple is easily frostbitten, which will seriously damage the nipple and seriously affect milk production. Cows in poor health will have a decline in disease resistance after being frozen. Therefore, each cattle farm should be equipped with a delivery room, a semi-shed plastic shed, or a place where it can be protected from the cold in advance, so that when the weather is cold, the delivery cows, newborn cows and poor health cows can be kept inside, which can effectively reduce losses.
