Nutritional aspects
Nutritional attributes 
The ramie plant, grown mainly as a fibre crop, is also a source of nutritious green feed. Ramie is palatable to all classes of domestic livestock.
The leaves and tops, unlike the stems, have a low fibre content and are rich in protein, minerals, lysine and carotene. The nutritive value of ramie has been described as similar to that of lucerne, which it can, however, greatly outyield. When ramie is grown for fodder, up to fourteen cuttings a year can be taken from established crops, yielding as much as 300 tons of fresh material (42 tons dry matter) per hectare per year. The foliage is palatable and has proved to be of value not only to stock but also to pigs and poultry.
Potential constraints 
The only problem associated with feeding ramie is its high mineral uptake, especially molybdenum on soils rich in this element; this can be corrected by adding appropriate levels of copper sulphate to the diet.
Ruminants 
Ramie is an excellent feed for cattle.
Pigs 
As long as satisfactory ad lib mineral levels are achieved, ramie can be fed ad lib to pigs of all ages and acceptable production obtained.
