Description
Click on the "Nutritional aspects" tab for recommendations for ruminants, pigs, poultry, rabbits, horses, fish and crustaceans
Common names 

Groundnut skins, peanut skins, peanut bran, peanut skins

Synonyms

Description 

Groundut skins, which constitutes about 3% of the seed weight, are a by-product of the processing of groundnuts for human consumption. Peanut bran is a by-product of groundnut oil extraction. Both products contain the skins and variable amounts of seeds.

Nutritional aspects
Ruminants 

It has a bitter taste and can only be used in small quantities in ruminant feeds.
