Technical points about artificial deer breeding
â—† Mr. Zhang's Consultation from Changbai County: What are the key technical points in deer farming?
Answer: (1) When setting up a deer enclosure, it's important to choose a location that is dry, sheltered from the wind, and receives plenty of sunlight. The area should have good drainage and easy access to water. Deer require space for movement, so the enclosure should provide about 2–3 square meters per deer, with an additional 8–10 square meters of open space for exercise. The floor should be covered with slate or cement boards for easy cleaning of waste. A sturdy fence, around 2.5–3 meters high, should be installed to prevent deer from jumping out.
(b) To increase antler production, farmers can construct simple plastic greenhouses based on local conditions. These greenhouses should cover approximately 125–225 square meters and be equipped with four mercury vapor lamps, each 100–150 watts, mounted about 2.5–2.7 meters above the ground. The light intensity should be around 500 lux. Starting from early spring, the lighting period should be extended by 50–60 days. This helps simulate longer daylight hours, which stimulates antler growth. The deer kept inside should be maintained under similar conditions as those in open areas. Another method is using sodium humate as a feed supplement. It improves appetite and metabolism, ensuring better nutrition for antler development.
(c) For young male deer, the first velvet antler is typically harvested around mid-June of their first year. For older deer over two years old, the antler should be fully developed into a two-pronged structure, with the top slightly concave. The third branch should be harvested before it fully develops. At this stage, the velvet antler is of high quality and value. Harvesting usually occurs between late June and late August. Before the procedure, an anesthetic should be injected into the deer’s hind leg. For a deer weighing around 100 kg, 0.3 ml of succinylcholine injection is recommended, followed by 6 ml of 25% nikethamide injection immediately after. This ensures the animal remains calm and comfortable during the process.
By following these techniques, farmers can enhance both the health and productivity of their deer, leading to higher-quality antlers and better economic returns.
