Acacia genus is widely distributed throughout the arid and semi-arid regions of Sub-Saharan Africa, and Acacia karroo is the most widespread among the acacias in Southern Africa (Barnes et al., 1996).
Description of Acacia karroo: Acacia karroo Hayne is synonymous with karroo thorn or sweet thorn, belonging to the family called Fabaceae (International Legume Database and Information Service, 2010).
Acacia karroo contains thorns which are long (2-5cm), straight and whitish with brown tips and paired at the nodes (Teague, 1989).
Several methods have been devised by researchers to eradicate encroaching Acacia karroo with little or no success (Strang, 1974; Trollope, 1974).
Nutritive value of Acacia karroo leaf meal: The feeding value of forages depends on the balance between the nutritive components of the plants, the digestibility of such nutrients, the metabolism of absorbed nutrients and the quantity of nutrients ingested by the animal (Adesogan et al., 2006).
The use of Acacia karroo as dry season protein supplements has been extensively reported in literature (Mapiye et al., 2011; Marume et al., 2012; Ngambu et al., 2013).
karroo leaves observed in Tables 1 and 2 can be ascribed to differences in populations, soils, climate, season, stage of growth, browsing pressure, assay methods and presence of secondary plant metabolites, respectively (Aganga et al., 2000; Mapiye et al., 2011).
karroo leaves on animal production: Condensed tannins (CTs), also known as proanthocyanidins, are phenolic plant secondary compounds that are found in plants, leaves, bark, fruit, wood and roots (Hassanpour et al., 2011).
The presence of CTs in Acacia karroo has been documented by several authors (Mokoboki et al., 2005; Ngambu et al., 2012; Gxasheka et al., 2015).
Condensed tannins in Acacia karroo have been implicated in increasing faecal N and negative N retention in goats (Dube and Ndlovu, 1995; Mapiye et al., 2011).
