The most common root crops used in the feeding of farm animals are fodder beet, sugar beet and turnip. The main characteristics of roots are their high moisture content 75-90% and low crude fibre content. The organic matter of roots consists mainly of sugars (50-75%) and is of high digestibility. Roots are generally low in crude protein content and degradability of the protein in the rumen is very high (80-85%). Root crops are generally poor source of vitamins.
