Key Technical Points for Safe Overwintering in Velvet Deer Farming
Cold protection and insulation. When the outside temperature is 15°C, a portion of the nutrients taken in from feed must be diverted to resist the cold in order to maintain normal body temperature. At this time, in northern regions, 1 to 2 layers of bundled corn stalks should be set up outside the deer shed walls to block wind and cold.
