Description 

Shrub or tree up to 20 m high with blackish-brown bark and leaves 5-10 cm long, usually having long straight, white thorns, at the base. Flower heads golden yellow and spherical. Pods straight and slender, slightly constricted between the seeds, dark brown 5-10 cm long and 0.5 cm broad. Occurs along rivers.

Nutritional aspects
Potential constraints 

No prussic acid in the leaves and thorns.

Ruminants 

The leaves and fruit seldom eaten by stock, probably because of the long thorns.

Pigs 

Feeding Acacia karroo leaf meal at low (10%) inclusion level in the diet of pigs depressed nutrient digestibility, increased endogenous protein secretion and increased the activity of liver enzymes but did not reduce growth rate and was therefore considered as a potentially feasible technology (Halimani et al., 2005; Halimani et al., 2007).

Rabbits 

Feeding a diet containing 4% of Acacia nilotica leaf meal to growing rabbits did not result in differences in intake and digestibility. It was concluded that the amount of tannins in the diet was not high enough to have negative effects and that an inclusion rate of 4% was ideal for supplementation (Mashamaite et al., 2009).
