Abstract: | Rainfall variability and stocking rate in extensive ranching regions in the Northwestern Transvaal, South Africa, can have substantial influence on feed availability per animal and thus on beef production. A simulation model was developed to compare the degree of variability of revenues from four beef production systems, ranging from inflexible weaner marketing to marketing of 3-year-old oxen. Regression equations relating stocking rate and rainfall to calving percentage and weaning mass, and actual rainfall data over a period of 54 years were used in the analysis. Results indicated a lower mean revenue with a low income variation for the more intensive weaner system as compared to the more flexible 26–28-months and 39–42-months oxen production systems. Thus, in this area, characterised by low and rather variable rainfall, superior economic results can be obtained by choosing flexible production systems and marketing strategies. |
