Before and after the summer, it was during the production of the doe that scientifically raising the lactating deer and the lactating deer was related to the overall economic benefits of the deer. (A) post-natal feeding and management to carefully during the delivery of the deer, there should be special guard on duty. After giving birth to the deer, the mucus on the deer should be wiped dry, and the colostrum should be eaten as soon as possible. Then, ear numbers should be cut, and the deer should be fed back regularly. During the deer sucking, avoid odorous substances such as alcohol, soap, etc., and contact with the deer, otherwise the female deer will refuse to feed because of its odor. (b) Manual feeding should be promptly taken if the doe is dead or sick after delivery and cannot breastfeed or have insufficient milk. It is usually replaced with fresh milk or goat milk. If milk powder has to be used, the concentration of brewed milk powder should be slightly increased to meet the needs of growth and development of juvenile deer. The time, number of times and the amount of breast-feeding for artificial nursing are determined based on the age, birth weight, and development of the deer. In the absence of an empirical standard, the amount of artificial deer feeding in puppies can refer to the artificial feeding volume of calves. Insist on the disinfection of breast milk and breast milk to prevent bacteria from multiplying in milk and rancidity in milk. (3) Gradually overfeeding the feed The juvenile can feed fresh and juicy feed after 30 days of age, and gradually feed the concentrate. Concentrate can be fried with sorghum into a paste, crushed and then cooked with corn, soy mix can be, which accounted for 10% of soybeans, feeding amount from little to large, feeding 200-300 grams per day, 500 grams per day before weaning. Green roughage should be chopped and fed. In fact, the deer arrived at the age of 20-30 days and began to look for vegetable feed and can eat some tender green leaves. At this time, the nutritional source of the deer is still based on breast milk. When the juvenile deer weighs about 25 kilograms, it can leave the milk and switch to artificial feeding. (d) When the deer splits off the antelope and antelope, the two adjacent laps will be set at the middle of the pass. The mother and the deer will be all thrown into one of the laps, and then the doe will be placed in another lap. At first, the doe can be left in the deer circle for 1-2 days. After 4-5 days, the separate time is 1-3 hours at the beginning. After that, it is gradually extended. The door will open at noon and in the evening to let the mother move freely. The deer eats milk. To increase contact opportunities for human deer, whistle when feeding materials and water supply to stabilize the deer's temperament. (5) Carefully managing the deer after weaning should be reared in groups according to the sex of the deer, physical strength, and individual size. In the early days of leaving the doe, the deer will buzz more than ever and their mental state and appetite will be affected. The breeder must be patiently cared for. A deer eats a small amount of food, fast digestion, eating many times, within half a month from the milk can be fed 4--5 times a day, night feeding a rough feed, and gradually reached the date of feeding 3 times. Soybeans and corn can be cooked, a portion of corn flour can be made into cornmeal, and soybeans can be ground into soybean milk in proportion. At the same time, roughage can be given to poplar leaves, chopped green corn stalks, etc. Drinking water should be clean and adequate. In addition, attention should be paid to the supply of minerals, supplemental vitamins, selenium, trace elements, and other additives. Add salt and bone meal to the diet to prevent rickets and cartilage from occurring.
