Balance nutrition. During the overwintering period of farm cattle, in addition to feeding hay, crop stalks and silage, they must also feed enough concentrate, and use bran, cakes, cornmeal, etc., and boil them to be half-cooked. Concentrate feeding is generally 1.50-2 kg per adult cow per day; it is often supplemented with carrots, barley malts and other high-vitamin feeds; 10-20 grams of bone meal and 15-25 grams of salt are replenished per day. To supplement the lack of minerals.
Supply warm water. In order to digest the roughage consumed, the cattle must produce a large amount of digestive juice every day. At the same time, the body circulation, nutrient delivery can not do without water. Therefore, the consequences of lack of water in grazing cattle tend to be more serious than those in shortages, such as indigestion, reduced appetite, metabolic disorders, and reduced sensation. Therefore, winter must ensure that sufficient warm water is supplied to the cattle, and the temperature is based on the body temperature of the cattle. The minimum temperature must not be lower than 10°C.
Keep your air warm. Cattle have sparse coats, thin subcutaneous fat, poor cold resistance, and keeping warm and cold is an important means of promoting normal growth of cattle in the winter. The cowhouse temperature is preferably kept at 8-13°C. Plastic canopies can be used in winter in the north, but pay attention to the height of the greenhouse and the effect of windshield. In the north of the cowshed, wind barriers can be set. Grazing grass in the barn to reduce the loss of cattle heat. Please pay attention to ventilation at noon when the weather is fine and keep the air in the house fresh.
Seek grazing. In the winter, it is necessary to catch grazing at noon during the warm and sunny weather. The morning and evening temperatures are low and it is not appropriate to grazing. When grazing, choose a place where the leewards are sunny, so that the grazing cows eat while enjoying the sun, so as to promote the blood circulation of the bovine body and strengthen the body of the cattle.
Clean disinfection. In winter, the cowshed should be cleaned regularly, so that the cow dung should be excreted, the ground bedding be brushed regularly, and the cattle body should be brushed regularly, and sprayed with 10% quicklime water or 30% turfgrass regularly for disinfection.
Increase lighting. In winter, the weather is cold, the sunshine hours are short, there is little cattle activity, the resistance is low, and it is prone to parasitic diseases, rheumatism, and digestive diseases. Therefore, daily attention should be paid to the lighting of cattle. One or two 60-watt or 100-watt electric bulbs can be installed in the barn to light the cattle sooner or later. Rainy days can give full sunlight, in order to enhance the disease resistance of cattle.
