Deer embryo processing. After depilation and cleaning, the deer fetus or suckling deer are soaked in 60% Chinese liquor for 2-3 days, taken out and dried for 2-3 hours, molded into the posture when the newborn deer lies down, fixed with hemp rope, put in a drying oven, baked at 80-90℃ for about 2 hours, and let out the gas in the abdomen, and stop baking when it is nearly ripe, and then take out and air-dry repeatedly until it is dry. Deer fetus can also be processed into deer fetus powder for preservation.
