Sommario/riassunto: | Livestock biodiversity is integral to our culture, history, environment, economy and, most importantly, our future. Thousands of livestock breeds, from relatively small genetic pools, have evolved over time to suit particular environments and farming systems. This is both the result of natural processes and of human needs for specialized livestock - as our knowledge of genetics continues to increase we achieve a greater understanding of how this biodiversity evolved. This book offers a detailed and comprehensive overview of livestock biodiversity. It explores the history behind it, shows how |
