During the winter and winter season, there are fewer farm cattle, and some breeders tend to loosen their management. They mistakenly believe that there will be less farm work in winter and cattle will be arrogant. These are all incorrect ideas. In winter, the weather is cold and the cattle's body has more heat and needs to consume more nutrients. At the same time, the source and quality of feed in winter are poor and there is no green feed. Therefore, it should be carefully fed. As the saying goes: “Autumn roots, winter life, and spring spirits.†This shows the importance of winter cattle farming. In order to enable cattle to live healthy and safe winters, farmers need to devote more efforts to winter management of cattle. Increase the balance of nutrients for nutrition 1. One grazing cattle should feed 15 kilograms of hay every day, and one 1500-2000 kilograms of hay (such as rice straw, crop stalks, and silage) should be used in one winter. Feeding should be done with less feeding, 1 full feeding, allowing enough time for ruminating and resting after the cow is full. During the winter, the grazing cows also need to feed enough concentrates. They can use wheat bran, cakes and cornmeal, etc., and boil them to be half-cooked. Concentrate feeding amount, generally 1.0-1.5 kg per adult cattle per day, and often feeds carrots, barley malts and other high-vitamin feeds, while each head cattle supplements 10-20 grams of bone meal daily, 15-25 Grams of salt to supplement mineral deficiencies. The supply of warm water for disease prevention and treatment of farm cattle needs to secrete a large amount of digestive juice every day. At the same time, the circulation and nutrient transport of cultivating cattle are also inseparable from moisture. 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, it is necessary to provide sufficient warm water for the cattle in winter. At the same time, it is necessary to strengthen the prevention and treatment of diseased cattle. Special attention must be paid to the control of chilling chills. The main method for preventing the chilling disease is to keep the cattle sheds dry and clean, and the sheds should be cleaned regularly, so that the ox dung can be used diligently. Pad dry soil, ground grass, brush cattle regularly, and regularly disinfect with 10% quicklime or 30% ash. Ventilation and warmth increase lighting protection against cold and warmth is an important means to promote the normal growth of cattle in winter, and the temperature of cattle house is best kept at 8°C-13°C. The cowshed in winter should be built on a leeward place, and the cowhouse on all sides should be repaired as soon as possible before the onset of winter so that the doors and windows can be covered with straw curtains to ensure no wind and snow. In the barn, grass is used to reduce the heat loss of cattle and keep the barn dry and clean. Please pay attention to ventilation at noon when the weather is fine and keep the air in the barn fresh. In addition, cold winter weather, short days of sunshine, low cattle activity, low resistance, susceptible to parasitic diseases, rheumatism and digestive tract diseases. Therefore, 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 increase the illumination of the grazing cows sooner or later, and the full sunlight can be given on rainy days. Look for grazing to enhance the physique to catch grazing at noon in the warm and sunny weather in winter, early and late temperatures are low, not 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, promote the formation of bovine vitamin D, and strengthen the body and disease resistance of the cattle. Winter campaigns should avoid making cows sweat, because sweating cows are susceptible to frostbite and cold after being suspended.
The appearance is tan, and the cork is red-brown at the flaking; there are intermittent stripes on the branches, nodules are enlarged, and the shape is like a bead. Most of the hard and delicate roots and fibrous roots are born, and some surfaces are smooth and smooth, such as stalks. It is commonly known as "crossing the river branches" or "crossing bridges"; there are brown scales on the upper part, and there are residual stems or petioles that have not been cleaned at the top. The quality is firm and hard, the section is irregular, the skin is dark brown, the wood is golden, the rays are cracked, the central pith is red and yellow, and occasionally hollow. Odorless, very bitter taste, chewing saliva can be dyed red and yellow. It is better to use fat, beaded, solid, red-yellow, no residual stems and fibrous roots.
