A hands-on barn and field guide designed for quick and easy use, presenting a thorough examination of animals in the barn and then listing symptoms with nearly
200 color pictures of what the farmer is seeing, possible conclusions, and then giving a concise set of treatments. The treatments are ones that Dr. Karreman has found to work consistently well during 15 years in the trenches working with organic cows. Basic backgrounding in the fundamentals for organic and holistic thinking about livestock is included in the introduction. The companion guide to Treating Dairy Cows Naturally, this book includes an easy-to-follow visual and hands-on physical exam section, features nearly 100 case studies organized by symptoms, and offers valuable field-tested natural treatments.

"Treating Dairy Cows Naturally: Thoughts and Strategies"

Dr. Hubert Karreman, a dairy veterinarian in Lancaster County, PA, who works with 60 organic dairy farms, has written a book called "Treating Dairy Cows Naturally: Thoughts and Strategies", now in its 2nd printing with new pictures, diagrams and an easier to read format.

In this groundbreaking work Dr. Karreman invites us to journey in to the world of dairy cows from a truly holistic perspective. With much thought and research, he builds a foundation from which to view dairy cows as animals that occupy a unique agro-ecological niche in our world. From within that niche, he describes how cows can be treated for a wide variety of problems with plant-derived and biological medicines. Drawing upon veterinary treatments from the days before synthetic pharmaceuticals, and tempering them with modern knowledge and clinical experience, Dr. Karreman bridges the world of natural treatments with life in the barn in a rational and easy to understand way. In describing treatments for common dairy cow diseases, he covers practical aspects of biologics, botanical medicines, homeopathic remedies, acupuncture and conventional medicine. By incorporating conservation principles, he also alerts us to the need of keeping our waterways clean - both for our health and the health of the cows. This book should serve as a useful reference for years to come. .

The book is 412 pages, hardcover, and costs $40.00
