Discipline: development; Key words: entrepreneurship, dairy cattle, food security, indigenous knowledge systems.

The authors referenced below did a case study in the local municipality areas of Matatiele and Groblersdal to explore and identify the drivers of dairy smallholder farmer decisions. They found the following as determining factors:

  • dairy farming is dominated by male farmers who were over 60 years old;
SEASONAL TRENDS OF MASTITIS INCIDENCE IN DAIRY PRODUCTION REGIONS.

Dairy farms often experience a summer through autumn rise in somatic cell count (SCC) with some farms affected more than others.  The extent to which climatic factors contribute to this summer rise in SCC in South Africa is unknown although weather is blamed anecdotally. Consequently, the value of heat abatement or other preventative intervention cannot be established. The relative effect of season and/or heat stress on milk production and SCC is likely to be unique to South African conditions and therefore this formed the basis of the study cited below.
