Ask for deer feeding and management techniques in winter?

(agricultural Wealth net) ask for deer feeding and management techniques in winter? 1. Feeding and management of male deer during the overwintering period the overwintering period of male deer includes the recovery period of mating and the early stage of antler growth. From early November to late March of the following year, the male deer is in the cold winter season, and the deer is neither breeding nor antler, so it is in the non-production season. Due to the physical consumption and seasonal weight loss during the breeding period, the physique of deer is relatively weak, the feed intake increases during the overwintering period, and the physique recovers quickly. For the old, weak, sick and disabled deer, we should consider increasing nutrition, and at the same time, increasing nutrition in the early stage of antler can also be released in advance, so as to lay a good foundation for antler. 1. Gradually restore nutrition to ensure safe overwintering. After 12 months, the sexual desire of the deer gradually decreases and the appetite increases gradually. Because it is in the cold winter, the physical consumption is also large. The deer farm should gradually increase the addition of concentrate, which is generally 1.1 kilograms for adult sika buck and 2.5 kilograms for red deer. At the same time, adequate roughage is provided. Lack of green roughage in winter, you can use leaves, straw, silage and other feed, while ensuring drinking water, preferably warm water. In the early stage of raw antler, the amount of concentrate feed should be appropriately increased to prepare for the release of raw antler of deer. 2. Adjust the deer herd and eliminate the old, weak and low-yield deer. Winter is the season to test the physical condition of deer. According to the actual situation, deer farms should appropriately eliminate the old, weak and low antler-producing deer, and separate groups of deer that produce good antler but old and weak, so as to prevent the phenomenon of death due to the lack of feed for the old and weak deer. 3. Moistureproof, heat preservation and hygiene. There is a lot of rain and snow in winter, wet and cold, so the deer farm should clean the enclosure in time and keep it clean and dry. In case the deer slips and falls, causing unnecessary casualties; if possible, dry matting grass should be laid in the enclosure to create a warm and comfortable environment, and at the same time, the deer should be driven in sunny days to exercise properly and maintain healthy and exuberant vitality. 2. Feeding and management of female deer during pregnancy December to April of the second year is the period when the mother deer pregnancy and embryo grow and develop into a mature fetus in the mother's womb. During this period, in addition to maintaining their own physical needs, female deer must also provide a variety of nutrients to the fetus so that the fetus can grow and develop healthily. 1. Strengthen nutrition by stages. In the early stage of pregnancy, the nutritional needs of female deer are mainly focused on quality. In production, a variety of feed raw materials should be selected for feed preparation and balanced allocation, so that energy, protein, mineral elements and vitamins can meet the needs of female deer and fetus. In the later stage of pregnancy, concentrate should be fed physically, and the amount of feed should be increased. At the same time, the volume of diet should be considered to prevent deer from eating too much and squeezing the fetus. Should also maintain a suitable physical condition, in order to prevent excessive fat caused by dystocia. 2. Create a comfortable living environment. Do not raise too many female deer in each ring, so as not to cause crowding or even miscarriage; the deer farm during pregnancy should be quiet. Keep the enclosure clean and dry. 3. Exercise properly and do a good job in prenatal work. Pregnant female deer have less exercise in winter and should be driven and domesticated at a regular time every day. In the third trimester of pregnancy, protective rails should be set up to check and repair the loops, and bedding grass should be added to prepare for the smooth birth of female deer.
