Voluntary Food Intake and Diet Selection in Farm AnimalsJohn Michael Forbes CABI, 01.01.2007 - 453 Seiten The feeding of farm animals directly effects their growth, health, reproduction and ultimately their economic value and is consequently one of the most studied areas of animal science. Building on the first edition and its predecessor, "The Voluntary Food Intake of Farm Animals," Forbes has produced an up-to-date and more focused examination of developments in the understanding of voluntary food intake and new ideas and studies relating to diet selection. Chapters have been reorganized and updated to provide a more streamlined approach. |
