Animal welfare science is widely understood to have begun in the 1960s, but in this book, first published in 1839, veterinarian Youatt was combining Christian ethical reflections with scientific observation in order to sketch out an ethics of animal well being to be applied to agricultural practices. An introductory essay by Preece (political philosophy, Wilfrid Laurier U., Canada) places the work in philosophical and scientific context. Annotation (c) Book News, Inc., Portland, OR (booknews.com)
