First, it is difficult for deer to reproduce.
Many people may not know that they have never raised deer before, but people who specialize in raising deer must be very clear. Deer are difficult to breed, and the food they eat is very picky. It is still more troublesome to really grow up. It takes a long time for deer to be pulled out for human consumption when they are young. Moreover, in the process of feeding, feeding deer is also a very big problem, because deer is an expensive animal and its food is picky. If you feed it with feed for cattle or sheep, the deer may not eat it at all.
Second, the reproductive rate of deer is very low.
Under normal circumstances, if the breeder raises sheep or cattle, he will find that calves under the cattle and sheep can grow up quickly, and they will soon become adults under normal feeding, and the adult cattle and sheep can reproduce again every year. However, the growth and reproduction of deer are very slow. If the breeder wants to wait for the deer to grow up before eating venison, it can be said that it is very difficult. During this period, it takes a lot of manpower, financial resources and material resources, and it takes a long time. Therefore, it is not easy for a farm to want a large number of breeding roads, which is simply in short supply, so few people eat venison now.
