The period of breeding wild roe deer is short, the feeding cost is low and the economic benefit is high. The young roe deer can grow into an adult roe deer about 400 days after birth, and its weight can reach 40kg. In the period of sexual maturity, the wild roe deer breeds one child a year and gives birth to 2 to 3 lambs. The baby begins to learn to feed about a month after birth. At this time, the baby can be weaned, and the weaned baby should be reared in groups. The breeding life of roe deer is about 10 years. At present, the price of wild roe deer meat is expensive, the purchase price is 150yuan / kg, and the net income of roe deer is more than 1000 yuan in one and a half years. Relevant professionals predict that in the past 10 years or more, the supply of roe deer will be in short supply, and the price of each pair of roe deer will be 4,000 million 5000 yuan.

After the baby is born, it looks like a sika deer, with four straight white spots in its brown hair. It usually takes a year to get there. To sexual maturity. In the first year, the two horns have no branches, in the second year, there is one bifurcation in each corner, and in the third year, each corner has three bifurcations. The bifurcation of this angle may be related to age. The horn of the razor is antler when it just grows. If there is no saw antler within a certain period of time, it will automatically ossify and become hard horn. Starting from November, in order to adapt to the cold winter environment, razor began to increase hair on the basis of the original brown-red hair, growing a thick and long gray-white hair, covering the original brown hair. A thick layer of white hair grows around the anus and penis. On the one hand, this transformation of hair is to adapt to the cold winter environment, on the other hand, this color similar to the environment can effectively prevent prey from being caught. Around the middle of March of the second year, the increased hair began to fall off and changed from grayish white to brownish red.
