  1. The use of the cellulase digestion procedure for indexing the dry matter digestibility of forages

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The in vitro cellulase technique was compared with the rumen liquor technique and found to be more efficient for the indexing of the dry matter disappearance (DMD) of forages. A cellulase enzyme concentration of 80 IU/gDM gave a satisfactory linear...
  2. Seasonal herbage production from two range types in southern Mozambique

    Seasonal herbage production from two range types in southern Mozambique

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Estimating ideal stocking rates in southern Mozambique based on range productivity is difficult since forage and foggage production of range types receiving different amounts of rainfall have not been quantified to date. Exclosures were constructed in upland and alluvial range...
  3. Ecological effects of fire-breaks in the montane grasslands of the southern Drakensberg, South Africa

    Ecological effects of fire-breaks in the montane grasslands of the southern Drakensberg, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Fire-breaks, by legislation, are burnt annually before mid-winter in the southern Drakensberg, affecting 5–10% of the landscape, and resulting in marked selection for the early season flush by both livestock and wildlife. This study investigated whether this severe defoliation regime...
  4. The distribution of sweetveld and sourveld in South Africa's grassland biome in relation to environmental factors

    The distribution of sweetveld and sourveld in South Africa's grassland biome in relation to environmental factors

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The distribution of sweet‐ and sourveld in relation to climate, parent material and soil nutrients has been examined in South Africa's grassland biome. Sourveld occurs in areas with high water supply and where parent material gives rise to soils with...
  5. AU Triumph, Johnstone and Kentucky 31 tall fescue pastures versus maize silage in diets for lactating dairy cattle

    AU Triumph, Johnstone and Kentucky 31 tall fescue pastures versus maize silage in diets for lactating dairy cattle

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The performance of lactating dairy cattle fed on a maize silage (S) dry‐lot scheme was compared with that of lactating dairy cattle switched abruptly from a dry‐lot regime to graze endophyte‐free Johnstone (J), Kentucky 31 (K), or AU Triumph (T)...
  6. Predicting animal production on sourveld: A species‐based approach

    Predicting animal production on sourveld: A species‐based approach

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    A simulation model was developed to predict average daily gain (ADG) in cattle and sheep grazing different species and swards of different species composition on Dohne Sourveld. The model was based upon measured ingestive and digestive characteristics of different grass...
  7. Influence of bushdumps on the herbaceous understorey in a mesic Eastern Cape savanna

    Influence of bushdumps on the herbaceous understorey in a mesic Eastern Cape savanna

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Studies of the effects of woody vegetation on herbaceous vegetation in southern Africa have focused almost exclusively on savannas with isolated trees with no attention given to multi‐species bushclump savannas. The influence of multi‐species bushdumps on herbaceous vegetation was investigated...
  8. Forage–cattle relationships in a communally managed semi-arid savanna in northern Zululand, South Africa

    Forage–cattle relationships in a communally managed semi-arid savanna in northern Zululand, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Development of extensive livestock production in KwaZulu-Natal is constrained by seasonal variability of rangeland production and low forage nutritional quality. A three-year study was implemented to determine the seasonal variation in herbaceous biomass and chemical composition of veld, animal weight,...
  9. Influence of mineral composition and rumen degradability of <em>Atriplex nummularia</em> (Hatfield Select F<sub>1</sub>) plants on selection preference of sheep

    Influence of mineral composition and rumen degradability of <em>Atriplex nummularia</em> (Hatfield Select F<sub>1</sub>) plants on selection preference of sheep

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    This study examined intraspecific variation in mineral composition and rumen degradability of Atriplex nummularia plants and the influence on selection preferences of sheep. Individual plants were categorised into high, medium and least preference groups by assessing the order in which...
  10. Seasonal dry matter production, botanical composition and forage quality of kikuyu over-sown with annual or perennial ryegrass

    Seasonal dry matter production, botanical composition and forage quality of kikuyu over-sown with annual or perennial ryegrass

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The seasonal growth and low forage quality of kikuyu restrict milk production. The aim of this study was to determine the yield and nutritional value of irrigated kikuyu over-sown with perennial, Italian or Westerwolds ryegrass grazed by dairy cows. The...
