  1. The logistic model-generated carrying capacities, maximum sustained off-take rates and optimal stocking rates for Kenya's commercial ranches

    The logistic model-generated carrying capacities, maximum sustained off-take rates and optimal stocking rates for Kenya's commercial ranches

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    This paper deals with the derivation of logistic models for cattle, sheep and goats in a commercial ranching system in Machakos District, Kenya, a savannah ecosystem with average annual rainfall of 589.3 ± 159.3mm and an area of 10 117ha...
  2. Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Determination of carrying capacity for mixed‐ or multi‐species grazing systems is complex. Commonly, each species is compared to the standard large stock unit (LSU) used in conventional agriculture. However, this approach does not allow for ecological separation, and thus overlooks...
  3. The ecological potential of the kudu for commercial production in savanna regions

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    This paper considers the choice of a browsing ungulate to supplement cattle in savanna regions susceptible to problems of bush encroachment, and evaluates the kudu in particular. Relevant aspects of its ecology considered include (i) the vegetation components utilized at...
  4. Die evaluasie van droëland <em>Cenchrus ciliaris</em> L. cv Molopo vir speenkalf‐produksie in die sentrale grasveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Speenkalfproduksie op droëland Cenchrus ciliaris‐weiding is by drie veeladings onder aanhoudende beweiding ondersoek (1978–83). Verskille in beskikbare bogrondse fitomassa (BBF), speenmassa en die ekonomie van speenkalfproduksie word bespreek.
  5. Desmodium: A low‐cost pasture for the eastern cape coastal region

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Desmodium intortum is well suited to the East London Coastal area for beef production under dryland conditions. Although slow to establish, satisfactory livestock production is maintained under a low fertilizer regime. Experimental results indicate stocking rates for maximum production per...
  6. ‘n oorsig oor staande hooi in die sentrale grasveld met spesiale verwysing na <em>digit aria eriantha</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Literatuuroorsig oor die gebruikswaarde van tropiese grassse as staande hooi, in die winter, word voorsien. Die invloed van klimaat op die keuse van spesies en bestuur van die grasse, gedurende die voorafgaande groeiseisoen, word bespreek. Meer onlangse gegewens oor...
  7. Interrelationships between veld condition, herbage mass, stocking rate and animal performance in the Tall Grassland of Natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Grazing trials were established at three sites in the Tall Grassveld of Natal. The objectives were to determine (a) patterns in herbage mass in relation to veld condition, stocking rate and commencement of spring grazing, and (b) animal performance in...
  8. A conceptual stocking rate model for the moderately dry mixed and sourveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Results for the 1986/87 season from 15 grazing trials situated at five sites were used to develop a qualitative model describing the relationships between stocking rate and herbage mass and between stocking rate and individual animal performance. Although it cannot...
  9. A comparison of four different standards of reference for the animal unit for Determining stocking rate

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    No single standard of reference for the animal unit (AU) for determining stocking rates has materialized. Often, therefore, it is not clear which standard of reference for the AU or which method of determining stocking rate has been used in...
  10. Die invloed van bemesting op die spesiesamestelling en basale bedekking van beweide veld in die Potchefstroom‐omgewing

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The impact of fertilization on veld in the Potchefstroom area was investigated. Nitrogen and phosphorus were applied annually from 1972/73 until 1981/82. The control plots and the fertilized plots were grazed with year‐old steers. Species composition and basal cover were...
