54th Annual SASAS Congress 2024
SASAS Congress 2024, 3-5 July 2024, East London Convention Centre, South Africa
Theme: Animal Science and the Environmentally Stressed Production Animal
The organisers deemed this to be an appropriate theme taking into account the ever changing landscape for animal production and especially the associated changing climatic conditions. The aim of the congress is to highlight the different disciplines covered by the field of animal science as well as closely related disciplines in other fields and their relevance to the environmentally stressed production animal. Traditional animal science disciplines such as Genetics, Physiology and Nutrition combined with Health/Animal Welfare, Grazing Resource, Economics and the Production Environment will be addressed by a host of local and international speakers. An in depth discussion on animal welfare will form part of the congress and this relevant topic will also be dealt with during an interesting student debate and panel discussion led by internationally recognised and well
respected experts.
