  1. The production potential of an <em>acacia karroo</em> community utilized by cattle and goats

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An investigation was undertaken to determine the relationship between bush density and animal production/ha as well as between bush density and profitability/ha. Boer goat farming was found to be more profitable in the short term than beef ranching. The best...
  2. Plant palatability assessment and its implications for plant‐herbivore relations

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An objective method used to assess the palatability of the foliage of woody plant species to kudus, impalas and goats is described. Observations were made on the feeding behaviour of tame animals in the Nylslvey Nature Reserve in northern Transvaal...
  3. The rate of consumption of bush and grass by goats in a representative <em>acacia karroo</em> savanna community in the Eastern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Consumption of browse and grass in a representative Acacia karroo savanna community was measured. Acacia karroo was preferred to grass. It was selected almost exclusively when available at high leaf densities. Grass was consumed in significant amounts only when approximately...
  4. Effect of intensity and frequency of defoliation on aerial growth and carbohydrate reserve levels in <em>Acacia karroo</em> plants

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Acacia karroo trees were defoliated by goats at two intensities and four frequencies; 2, 4, 8 and 12‐weekly. Leaf accumulation and carbohydrate reserve levels were compared to a non‐defoliated control, and to plants (defoliation controls) which were defoliated for the...
  5. The response of <em>Acacia karroo</em> plants to defoliation of the upper or lower canopy

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The response of Acacia karroo trees to defoliation of either the upper or lower canopy only, was compared experimentally with that of plants whose whole canopies had been defoliated at a range of defoliation levels. These plants were very sensitive...
  6. Simulating browse production and response of <em>Acacia karroo</em> to defoliation I. Model description and sensitivity analyses

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The model is aimed at synthesizing existing data to enhance the understanding of this data and explore the consequences of possible browse management strategies. It gives a good reproduction of the shoot and leaf growth responses used to develop it...
  7. Simulating browse production and response of <em>Acacia karroo</em> to defoliation II. Evaluation of browse management systems and strategies

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    To assess management implications, a model was used to simulate the response of Acacia karroo to a wide range of different climatic patterns and defoliation regimes. The model predicts that if poor growing conditions initiate growth later in spring than...
  8. Browsing of <em>Grewia occidentalis</em> by domestic stock in a South African savanna: the influence of bush clumps

    Browsing of <em>Grewia occidentalis</em> by domestic stock in a South African savanna: the influence of bush clumps

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    In South African karoo categorised by multi-species bush clumps, skirted shrub species appear to physically defend the palatable shrub Grewia occidentalis against browsing by eland (Taurotragus oryx). Skirted shrubs appear to defend G. occidentalis by preventing access to plants and...
  9. Seasonal variation in forage quality and mimosine contents of two varieties of <em>Leucaena leucocephala</em>

    Seasonal variation in forage quality and mimosine contents of two varieties of <em>Leucaena leucocephala</em>

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Seasonal variation in forage quality and mimosine contents of two varieties (cultivars Cunningham and Spectra) of Leucaena leucocepha/a were evaluated. Cultivar (cv.) Cunningham was available throughout summer, autumn, winter and spring seasons while cv. Spectra was available during summer, winter...
  10. Estimation of grazing by herbivores from analysis of dung

    Estimation of grazing by herbivores from analysis of dung

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Two phenolic acids, p-coumaric and ferulic acid, can be liberated from grass material by mild alkaline hydrolysis and resolved by thin layer chromatography (TLC). The two acids can also be recovered from the dung of various herbivores and their presence...
