  1. Longer rest periods for intensive rotational grazing limit diet quality of sheep without enhancing environmental benefits

    Longer rest periods for intensive rotational grazing limit diet quality of sheep without enhancing environmental benefits

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Intensive rotational grazing systems (also called cell grazing, holistic grazing or time-controlled grazing) are often implemented to improve production and environmental outcomes. Over recent years there has been considerable interpretation and adaption of the holistic principles that guide the management...
  2. Composition of colostrum and milk of South African indigenous <em>Nguni</em> goats grazing natural pasture and supplemented with concentrate

    Composition of colostrum and milk of South African indigenous <em>Nguni</em> goats grazing natural pasture and supplemented with concentrate

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Samples of colostrum, early and late lactation milk from thirteen South African indigenous Nguni goats (SAING) were analysed for contents of total solids (TS), solids-not-fat (SNF), fat, protein, lactose, ash and energy. Relationships between colostrum or milk and some parameters...
  3. Impact of sustained drought on a semi‐arid <em>Colophospermum mopane</em> savanna

    Impact of sustained drought on a semi‐arid <em>Colophospermum mopane</em> savanna

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Vegetation change on different substrate types was measured over 15 years in semi‐arid Mopani Veld. Baseline data were collected in the terminal year (1982) of a decade of above‐average rainfall, whilst the period of monitoring was characterised by below‐average rainfall,...
  4. A comparison of highveld fodders and fodder flows for growing out long yearling steers

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A fodder flow/animal experiment 40,8 ha in extent (7,5 ha irrigated), with 19 paddocks, was carried out over a two and a half year period.
  5. Veld composition in relation to grazing capacity <em>die verhouding tussen veld samestelling en weidingskapasiteit</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Present methods of evaluating veld composition in relation to grazing capacity can be criticised on grounds of subjectivity, especially with regard to the assignment of relative values to the constituent species. Data relating to botanical composition and estimated grazing capacity,...
  6. Long term nitrogen and phosphorus application to veld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The long term effects of a 5N x 3P factorial fertilizer application trial on hay yields, botanical composition and soil properties of veld are presented. Significant increases in hay yields were recorded during most years. There was a strong correlation...
  7. The effect of thirty years of burning on the Highland Sourveld of Natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A veld condition assessment was used to determine the effect of past burning treatments on the species composition of Highland Sourveld at Cathedral Peak. Veld condition scores in grassland protected from fire were significantly lower than where veld had been...
  8. Pasture‐use patterns on dairy and beef farms in the natal midlands

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Pasture sites for each of the species grown are classified for both dryland and irrigated pastures in the Natal Midlands. Only six species viz. kikuyu, Italian ryegrass, Eragrostis curvula, Festuca arundinacea (tall fescue), Dactylis glomerata (cocksfoot) and Trifolium repens (white...
  9. Towards a method of assessing the veld condition of the valley bushveld in the Eastern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Currently, no technique is available for assessing the condition of Valley Bushveld in the Eastern Cape. The objective of this investigation was to develop a method of scoring bushveld according to its productive condition. It was established, through principal component...
  10. Preliminary observations on the ability of goats to control post‐burning regrowth in <em>acacia nigrescens/combretum apiculatum</em> Savanna in Botswana

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A ten hectare block which had been burned with an intense surface head fire was stocked at the rate of one goat per hectare to control the woody regrowth. After one year the block was subdivided and in one half...
