Description 

Biennial plant with thick roots of different sizes, forms and colours. In the second year a stem up to 1 m high is produced from the top of the tuber. It is cultivated in cooler climates, but it cannot withstand frost and must be harvested before the beginning of cold weather. There is an intermediate range of fodder beets between mangolds and sugar beets; these are mainly used in northern Europe.

Nutritional aspects
Nutritional attributes 

Although fresh sugar beets are not often fed to animals, they are well liked by cattle and pigs and may be included in their diets.

Potential constraints 

It is recommended to cut or mash the sugar beets to eliminate the possibility of one lodging in the esophagus and causing bloat. This is likely more of a problem with small rather than large sugar beets. Crushing the sugar beets by driving over them with a tractor may be sufficient (Rust et al., 2008).

Ruminants 

Sugar beets have a nutrient profile similar to corn silage. They may be more suited for use in cow and backgrounding/growing diets. The high sugar content may limit the use in backgrounding/growing diets to 20% of the DM. Up to 50% of ration DM could be used in cow diets (Rust et al., 2008).

Pigs 

Pig diets can beneficially include up to 20% sugar beet. The feed value of sugar beet is about twice that of mangold. It has a reputation for adversely affecting breeding capacity if fed to male stock (Göhl, 1982).

Rabbits 

Fresh sugar beets are useful feeds for pet rabbits. Because of their high sugar content, the amount given should be limited. They should never be fed frozen or thawed, mouldy or rotten (Lowe, 2010).
