Subterranean clover (Trifolium subterraneum)

IMPORTANT INFORMATION: This datasheet is pending revision and updating; its contents are currently derived from FAO's Animal Feed Resources Information System (1991-2002) and from Bo Göhl's Tropical Feeds (1976-1982).

Datasheet

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

Trèfle souterrain, subterranean clover, trebol subterraneo, sub clover

Synonyms 

Trifolium brachycalycinum (Katzn. & Morley) Katzn., Trifolium subterraneum subsp. yanninicum Katzn. & Morley

Feed categories 
Description 

An important pasture crop in some countries. Thrives in temperate climates on acid or neutral soils.

Nutritional aspects
Potential constraints 

If this clover constitutes a high proportion of the diet for sheep, breeding troubles may develop owing to the oestrogenic hormone in the plant.

Ruminants 

Unpalatable before flowering, but grazed heavily after the flowering stage.

Horses and donkeys 

In a comparison of the forage acceptability to horses of several grasses and clovers in the Southern USA, crimson, berseem and subterranean clovers were found to be highly palatable (McCann et al., 1991).
