The deer species should be selected based on the local climate, feed conditions, and biological characteristics of the deer. The south is hot and humid, and the aquatic plants are abundant. Although the deer intake is larger than that of the deer, the output of the deer antler is much lower than that of the deer, but the deer adapts to the climate and feed conditions in the south, and the meat production performance is good. Therefore, Guangdong, Yunnan, Guangxi, Guizhou, etc. The land continues to develop Sambar. Tarim red deer are of good quality, but poorly adapted in the Mainland, the mortality rate is as high as 23%. The white-lipped deer is suitable for the plateau climate and is only kept in western Sichuan, southern Gansu, and the Qinghai-Tibet Plateau above 6,000 meters above sea level. Tianshan red deer and sika deer have strong adaptability. Their antler and velvet products are welcomed by the market and have large stocks throughout the country. Because the deer deer price is cheaper than Tianshan red deer, the deer's stocking and development speed is faster and faster than Tianshan red deer. According to the excellent characteristics and basic characteristics of this species, the parents with high production performance, large body size, strong physique, beautiful body shape, resistance to roughage, strong adaptability, and strong disease resistance are selected as the deer, and the descendants are selected and determined. The deer's age for selection: the deer is 62 years old, the female deer is 23 years old; the deer 22 is produced; and the deer is 62. The skin is compact, full of elasticity, moderate coat color, bright luster, large or clear patches or hip spots, and obvious boundaries. The back line should not be too dark. The 12-year-old stag horns are short-thick and velvety-shaped, symmetrical and beautifully shaped. They have the characteristics of a variety of species.

The male deer's testicles are symmetric and well-developed. The male buck has been sexually active, and the fertility rate is high. The amount of antler production is higher than that of the same age production group. Number of selected species: Percentage of species of male deer based on the number of male bucks in the same age group. This is the time of artificial insemination. The female deer in the breeding female deer group, the core breeding population deer occupies; the deer should be more than. The female deer's physique is strong and healthy, and the scented deer are middle and top grade; the red deer should be superior and have good breeding condition.
