How to raise antler deer well

Deer belong to mammal class, Artiodactyla, Cervidae and deer. Deer with medicinal antlers are called antler deer. The main antler deer domesticated in China are sika deer, red deer, white-lipped deer and black deer. Pilose antler is a valuable traditional Chinese medicine, which has the functions of invigorating essence and tonifying pulp, tonifying blood, strengthening yang, strengthening muscles and bones and so on. Others, such as deer fetus, deer blood, deer tendons, deer whip, deer bone, deer meat, deer heart, deer liver and deer skin, are excellent pharmaceutical and industrial raw materials. Antler deer have high economic value and few wild resources, so @ 253deer is a promising industry. 1 the living habits of deer due to the short history of deer domestication, it still retains the wild habits of its ancestors. Hearing, vision and smell are well developed, timid and easy to panic, touch and run away quickly. In general, male deer are more aggressive than female deer. Under natural conditions, there are more than a dozen or dozens of animals in groups, and we can make use of its strong gregarious characteristics for domestication and grazing. Deer are herbivores with the physiological function of ruminating and feed on all kinds of plants all the year round. Grass, crop straw and branches of trees and shrubs are all good fodder. Under the condition of artificial feeding, bean cake, corn and wheat bran can be used as supplementary concentrate. 2 Deer house construction deer farm should choose the place where the terrain is high and dry, flat and wide, good drainage, plenty of sunshine, rich forage grass and shelter from the wind in winter. Because of the wild nature of the deer, the enclosure should be strong. The area of the deer house is 2 square meters per deer, the sports ground is 8 square meters per deer, and the fence is 2 square meters high. The circle should be covered with masonry or cement floor, and should be equipped with food trough and sink. 3The purpose of raising antler deer is to obtain velvet antler. Therefore, it is very important to raise male deer (male deer produce antler, female deer do not produce antler). Raising male deer can be divided into two stages: antler stage (February ~ April), antler stage (May ~ August), mating period (September ~ November) and mating recovery stage (December ~ January). After February, the weather became warmer and the sunshine became longer. In order to meet the physiological needs of raw antler of male deer, concentrate should be gradually increased. It can be fed with mixed concentrate 1~1.25kg and then increased by 70g / day to 2.3~2.4kg at the beginning of May. Among them, legume feed rich in protein should account for more than 50% and 60%. Salt, shell powder and other mineral feed should be fed 10g to 20g a day, and some additives such as animal auxin can also be fed if possible. After sawing the first stubble antler in July, the non-breeding buck should reduce the concentrate by 50% to 80%, so as to avoid fierce confrontation during the mating period. Male deer during the mating period become excited and aggressive due to sexual impulses and loss of appetite, so we should pay attention to care and minimize casualties. Feed should be diversified as far as possible, giving more green feed and root feed. Mixed feed 0.5~0.75kg every day. After the mating period, the nutrition of the stag decreases, coupled with the cold weather, it is easy to die season, so roughage should be sufficient, and it is appropriate to mix concentrate with 0.75~1kg every day. (4) the sexual maturity of female deer is over 2.5 years old, and that of male deer is 2.5-3 years old, but it is suitable for breeding at the age of 4-5 years old. The estrus cycle of female deer is 17-21 days, the estrous duration is 18-36 hours, and the gestation period is 224-231 days. The peak season of estrus of female deer is from September to November, showing excitement in proestrus and mid-estrus, shaking tail, swelling of vulva, hyperemia and transparent mucus. Mating is easy to conceive 12 hours after estrus. Male deer with high antler yield, strong physique and good genetic performance should be selected as deer. At present, the mating method of more than one male and more than one female is widely used, that is, one male deer with 20,30 female deer, the conception rate can reach more than 90%. The birth period of female deer is from May to June, with one litter per fetus, but not many twins. The lactation period is 2 months. Male deer produce antler antler at 1 year old and specification antler at 2 years old. 4-8 years old is the peak period of antler growth, and the production life span can reach 12-14 years old.
