Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

Author: Mkhize, NR ; Heitkönig, IMA ; Scogings, PF ; Dziba, LE ; Prins, HHT ; De Boer, WF Date: Aug 2015 Tannin concentrations fluctuate spatially and temporally within and among plant species, with con-sequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. ... Read more
Diet selection of goats depends on season: roles of plant physical and chemical traits

Author: Mkhize, NR ; Scogings, PF ; Nsahlai, IV ; Dziba, LE Date: May 2014 This paper reports on diet selection of goats offered six browse species (i.e. Acacia natalitia [Vachellia natalitia], Acacia nilotica [Vachellia nilotica], Dichrostachys cinerea, Grewia occidentalis, Gymnosporia maranguensis and Scutia ...

Nutrient and secondary metabolite concentrations in a savanna are independently affected by large herbivores and shoot growth rate

Author: Scogings, PF ; Hjalten, J ; Skarpe, C ; Hattas, D ; Zobolo, A ; Dziba, L ; Rooke, T Date: Jan 2014 Carbon-based secondary metabolites (CBSMs) such as tannins are assumed to function as plant defences against herbivores. CBSMs are thought to be inversely related to growth rate and nutrient concentrations because a physiological trade-off ... Read more
Seasonal variations in diet selection of Nguni goats: effects of physical and chemical traits of browse

Author: Fomum, SW ; Scogings, PF ; Dziba, L ; Nsahlai, IV Date: May 2015 Goats select some browse species more than others, given options. Seasonal trends of diet selection of Nguni goats indexed by intake were investigated in cafeteria-style experiments. The relationships between diet selection and plant ... Read more
Seasonal variations in nutrients and secondary metabolites in semi-arid savannas depend on year and species

Author: Scogings, PF ; Hattas, D ; Skarpe, C ; Hjältén, J ; Dziba, L ; Zobolo, A ; Rooke, T Date: Mar 2015 Semi-arid savannas are characterised by alternating wet and dry seasons and large inter-annual rainfall fluctuations that affect plant growth. Carbon-based secondary metabolites (CBSMs) vary inversely with growth and nutrients because of the ... Read more
