For improper feeding and management of adult deer, the negative consequences are generally only temporary. Once corrected, they can be restored in a shorter period of time. However, juvenile deer is in a stage of vigorous growth and development. If it is under poor feeding and management conditions for a long time, its growth and development are hindered, and its long-term adverse effects on its body shape, function, health, and production performance are various. Therefore, the correct feeding and management of young deer to improve the quality of deer, ensure full-living and full-strength, accelerate the development of the deer industry is an important part. Generally divided into three stages, are described as follows: 1, feeding and management of suckling deer. Mammalian deer generally refers to young deer (from early May to late August) that are born before weaning. The young deer during this period have rapid growth and great plasticity. The adequacy of nutrition directly affects the shape and weight of the deer. More than 10 days after the deer was born, he began to feed on feed and had a rumination phenomenon. When sucking on breast milk to obtain nutrition, he had to supplement nutrition earlier, that is, feed supplements earlier. Practice has shown that early-feeding juvenile deer have an increase of 28% compared with non-feeding at the beginning of the year. Under house feeding conditions, the nutrients in the milk of the doe after calving cannot keep up with the nutrients needed for the growth of the deer and must be supplemented in time. In addition, early supplementation can enable the deer digestive function to be fully exercised in the lactation period, develop adaptability to roughage, and adapt to the new feeding environment as soon as possible after weaning. While grasping the nutrition of the deer, it is necessary to prevent and treat the white deer, deer licking, and injury caused by collision and trampling. The addition of norfloxacin to the lactation diet of pups can prevent the occurrence of white deer in the deer, and significantly increase the survival rate of the deer. 2. Feeding and management of lactating deer. In late August each year, the deer sucks off milk at the end of December. The deer during lactation during breastfeeding, after supplementation, although the digestive function is given a certain amount of exercise, but due to the effect of sudden weaning, the late lactation of the special deer sucker is short, and the digestive tract is poorly exercised. Generally, it cannot be very much during the weaning period. Adapt to new feeds quickly. Therefore, in the first few days after weaning, we should give less concentrated material, and feed it to the easily digestible, nutrient-rich green feed and succulent feed in small amounts, and gradually increase the feed volume as the growth and development of feed intake of the deer increase. 3. Breeding deer feeding management. From the second year after birth to the end of August the following year is the breeding period. The male deer grows longer than the female deer. Well-developed bred male deer can grow first-fruit velvet, and well-developed bred deer can participate in breeding in the same year, that is, they can be put into production at the nymph stage. The bred deer is in an exuberant stage of growth and development, and its body, weight, and digestive organs are still growing at a high rate. To ensure adequate nutritional needs, the normal development of its various organ tissues, especially its full development of digestive organs, to eat a lot of nutrients, maximize productivity, and extend the useful life to lay a good foundation.
