This book is particularly interesting for those wanting to get a deeper knowledge on the ""state of the art"" of livestock systems in the six continents. This aspect is illustrated in the first section of the volume, while the second section describes the development of research activities in nineteen specific fields of animal science. Furthermore, the readers will certainly be interested by reading the ""contemporary issues"" manuscripts belonging to the third section.
