  1. Grazing of <em>raphanus sativus</em>. L (Japanese Radish)<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The performance of young woolled sheep was markedly better when grazing Japanese radish early in winter, when more leaf was available .Continuous grazing resulted in better performance than rotational or zero grazing.
  2. Performance of <em>Medicago sativa</em> under dryland conditions on the eastern Highveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Increased livestock numbers and improved animal performance based on dryland lucerne pastures requiring little or no nitrogenous fertilizer have been demonstrated to be feasible on the eastern Highveld. With large scale planting of lucerne‐based pasture (25% of arable land) 350...
  3. the utilization by sheep of winter and spring Smuts finger and Kikuyu pastures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An experiment was conducted on Smuts finger (Digitaria eriantha ssp. eriantha) and Kikuyu (Pennisetum clandestinum) pastures during a winter and spring period to study the effect of postruminal energy and/or protein supplementation on the selection pattern and performance of sheep...
  4. The influence of ruminant digestion on the germination of <em>Pennisetum clandestinum</em> hochst. ex chiov<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Approximately half of the viable Pennisetum clandestinum seed fed to sheep was found to be viable after passing through the digestive system. 82 % of the viable seed was excreted within 28 hours of ingestion with no viable seed being...
  5. Plant species dynamics in the Southern Tall Grassveld under grazing, resting and fire

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An analysis of temporal changes in botanical composition in a long‐term grazing trial indicates that species dynamics in the Southern Tall Grassveld of Natal are determined by the specific combination of grazing, mowing and fire impacts. Species composition of a...
  6. A critical analysis of veld management recommendations for sourveld in the south‐eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Surveys have shown that the grazing value of veld in the south‐eastern Transvaal is well below the estimated potential. Extension efforts aimed at rectifying the situation have been unsuccessful in that most recommendations have not been acceptable to producers. An...
  7. Seasonal influence on diet selection of sheep grazing a weedy dryland lucerne pasture

    Seasonal influence on diet selection of sheep grazing a weedy dryland lucerne pasture

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The experiment was conducted to determine the seasonal effects on the availability, chemical composition and digestibility of a grazing dry-land lucerne pasture, as measured on samples either collected by hand or with oesophageally fistulated (OF) sheep. The pasture was monitored...
  8. The use of trees, shrubs and herbs in livestock production by communal farmers in northern KwaZulu-Natal, South Africa

    The use of trees, shrubs and herbs in livestock production by communal farmers in northern KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    A survey of the use of trees, shrubs and herbs for livestock production was conducted through questionnaires among 90 farmers in the communal areas of northern KwaZulu-Natal in South Africa. The areas surveyed were located at Mtubatuba, Hluhluwe, Kwadlangezwa and...
  9. Using rain-use efficiency to explore livestock production trends in rangelands in the Transkei, South Africa

    Using rain-use efficiency to explore livestock production trends in rangelands in the Transkei, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We qualitatively describe the condition of communally managed rangelands in the Transkei, South Africa, using GIS and high resolution near-infrared imagery. Using livestock census data from 28 magisterial districts in the Transkei, we explored the trends in livestock biomass from...
  10. Defoliation patterns of three grass species in sourveld grazed by cattle and sheep

    Defoliation patterns of three grass species in sourveld grazed by cattle and sheep

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    A point‐based technique was used to determine the effects of grazing, due to stocking rate and cattle‐to‐sheep ratio, on the defoliation pattern of three grass species. At each of 100 systematically located points per grazing treatment the nearest plant of...
