Northeast spotted deer
The Northeast sika deer is the most widely bred local breed of sika deer in China, known for its large population and diverse types. It is raised across the country, with an estimated 560,000 individuals in captivity. This breed is considered a medium-sized deer, characterized by its elegant and agile appearance. Adult males typically stand 95–105 cm at the shoulder, measure about 100 cm in body length, and weigh around 135 kg. Their weight ranges from 60–130 kg between 1 to 6 years of age. Female deer are slightly smaller, with a shoulder height of 80–95 cm, body length of 75–90 cm, and a weight of 75–85 kg.
The Northeast sika deer has a striking head, large ears, a compact body, and well-proportioned, slender limbs. Its hooves are narrow and sturdy. The coat changes seasonally: it is brown or reddish-brown in summer and darker, chestnut-like in winter. Both seasons feature white spots, though those in winter are lighter. A distinct dark stripe runs along the back, measuring 2–4 cm wide, with 4–6 evenly spaced white spots on either side. More spots mean larger and rounder markings. The underbelly, legs, and inner tail are all white. Males have a curly mane on their necks, and white spots appear below the tail, encircling a black hair band. Male antlers usually have four tines, sometimes five, with no ice branches and underdeveloped brow tines. Antlers begin to grow in early April and fully mature by late August or September. They also possess a well-developed infratemporal gland, commonly called a tear nest, which is usually crack-shaped and secretes pheromones used for group identification and territorial marking.
The dried velvet from the Northeast sika deer averages 25–30 grams in weight. When the first antler reaches 5–6 cm, it is cut at 1.5–2 cm (known as "broken cricket"), and can also be harvested when it's still young. In that case, the weight can reach up to 150–200 grams. Adult deer are typically sawn three times, yielding 2.5–3.5 kg of fresh velvet. The best time for velvet harvesting is when the deer is 9 years old, producing over 3.3 kg of fresh velvet. The yield from the first and second cuts is 0.55 kg and 0.80 kg, respectively.
Male and female deer reach sexual maturity at 16–18 months, with breeding occurring between 16–28 months. Fertility rates range from 85–95%, while reproductive survival is 75–85%. The twin rate is approximately 3%. On average, live weight is 130–140 kg, with a slaughter rate of 55.0–64.1%, a net meat rate of 50–55%, and meat output of 65–75 kg. For females, the numbers are 65–85 kg, 51–54%, 38–43%, and 25–35 kg, respectively.
Due to its large population, high fertility, and strong adaptability, the Northeast sika deer has become a highly valuable breed. After many years of selective breeding, it produces high-quality velvet with good yield, resistance to roughage, and strong disease resistance. Crossbreeding between different varieties often results in superior offspring, making it a popular choice for farmers and breeders.
