Click on the "Nutritional aspects" tab for recommendations for ruminants, pigs, poultry, rabbits, horses, fish and crustaceans
Common names 
Camel thorn
Related feed(s) 
Description 
Tree up to 15 m high with dark-grey bark and straight leaves 5-6 cm long with white thorn at their base. Flower heads golden yellow, spherical. Pods almost straight or crescent-shaped, 10 cm long and 5 cm broad, covered by a grey feltlike indumentum. Occurs on savannahs and along river beds.
Nutritional aspects
Potential constraints 
Cases of stock poisoning frequently recorded; picked green pods suspected cause of poisoning.
Ruminants 
Fallen pods readily eaten by game and stock.
