Sheep like salt. There is a story of a "sheep cart" in the history of China.

Salt is a common mineral feed in sheep feed. Salt plays an important role in maintaining osmotic pressure, regulating acid-base balance and controlling water metabolism. Sodium is an important raw material for making bile, and chlorine constitutes hydrochloric acid in gastric juice and participates in protein digestion. Salt also has the function of seasoning, which can stimulate saliva secretion and promote amylase activity. Lack of salt can easily lead to indigestion, loss of appetite, pica, decreased utilization rate of feed nutrients and stunted growth, so it is necessary to feed the sheep with salt. There are many ways to add salt. In the grazing season, you can give the sheep salt once every 10 day, and each sheep prepares 15-20g, and sprinkle the salt on the slate for the sheep to lick. In the stage of house feeding, salt and concentrated feed can be mixed in a certain proportion and fed every day. Lambs are born to eat, and salt can be added to the feed.
