Foreword A World Conference on Animal Production is held under the auspices of the World Association for Animal Production at five-yearly intervals. This, the 10th WCAP is being hosted by the South African Society for Animal Science, a founder member of the WAAP, and the All-Africa Association for Animal Production. The Conference includes the 42nd Conference of SASAS and the 5th All-Africa Conference on Animal Production. The WCAP is a trend-setting conference that examines the scientific progress in livestock production and the effects that these have on the environment, economies and the quality of life of people. The theme of the 10th WCAP, New World; Future World, takes in the philosophy of the WAAP, conceptualising the place of animals in our daily existence. The theme focuses the sessions on constructing a future scenario for the various systems within animal production. The sessions alternate between and address the important issues that advance animal production and the quality of animal products through the responsible application of current and new technologies in animal physiology, animal genetics, production-enhancing molecules and resource and environmental management. Four special sessions address feed and food safety, dairy production and the role of livestock in developing communities. The World is at a critical stage where the rapid growth of populations and the general increase in prosperity are placing greater demands on natural resources, especially feeds and foods. While a significant proportion of the human population is experiencing a surge in welfare, the paradox remains that people around the world are struggling to cope with the basic needs for human dignity – enough food and the correct types of food, health management systems and social securities. Animal production is a non-negotiable factor in this complex equation. Animal production, though, relies on a range of input factors that collectively drive the systems to new levels of achievement. How knowledge is respected and applied in an ethical, responsible manner is fundamental to this process. It is a pleasure to welcome you to this integrated international conference on animal production. I hope that you will find it interesting and that you will be returning to your respective positions enthusiastic and brimming with new ideas. It will be particularly important that the principles discussed are taken forward and applied in every aspect of the livestock industry.
