Elm leaves are good pig feed. Fresh elm leaves contain 7.5% crude protein, 14% nitrogen-free extract, and quite a lot of minerals and carotene.

Feeding practice has proved that feeding pigs with elm leaves can not only promote the growth and development of pigs, but also make them less sick after eating them. Elm leaves can be fed green, made into pulp or ground into flour after air drying. It is best to add some dry concentrate feed (sweet potato powder, corn powder, sorghum powder, etc.). ) when feeding the green. Feeding pigs with elm leaf powder can also prevent vitamin deficiency.
