Research Note:Precision and accuracy of sward height distributions

Autor: Morris, CD, Zacharias, PJK

Publikováno v: African Journal of Range and Forage Science; Vol 16, No 2 (1999); 122-125

Double normal distributions can be used to resolve many sward height frequency distributions into two components representing the 'short' (patches) and 'tall' (non-patches)areas in the sward. The effect of sample size on the precision and accuracy of

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

Autor: Zacharias, PJK

Publikováno v: African Journal of Range and Forage Science; Vol 3, No 4 (1986); 117-121

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 80IU/gDM gave a satisfactory linear re

Perspective article:The evolving use of stocking rate indices currently based on animal number and type in semi-arid heterogeneous landscapes and complex land-use systems

Autor: Peel, MJS, Biggs, H, Zacharias, PJK

Publikováno v: African Journal of Range and Forage Science; Vol 15 (1998); 117-127

Methods of determining stocking rate based on metabolic mass, animal type and biomass are reviewed in the context of equilibrial/disequilibrial paradigms. In South Africa, the calculation of 'carrying capacity' is based on conversion of animal specie

Utilization of woody browse and habitat by the black rhino (Diceros bicornis) in western Itala Game Reserve

Autor: Kotze, DC, Zacharias, PJK

Publikováno v: African Journal of Range and Forage Science; Vol 10, No 1 (1993); 36-40

Black rhinoceros browse utilization was assessed at the woody plant species and community levels in western Itala Game Reserve, South Africa, using a semi-quantitative, plant-based method. These knowledge was used to hypothesize the possible effects

Species response to grazing in the Smaldeel area of the Eastern Cape

Autor: Martens, JC, Danckwerts, JE, Zacharias, PJK

Publikováno v: African Journal of Range and Forage Science; Vol 13, No 1 (1996); 29-36

Species composition of the grass layer was measured in plots selected to cover a wide spectrum of condition states in six range types. This was achieved by placing 257 sample plots along contrasting fence-lines in adjacent plots on either side of the
