See if your local library can get you a loan copy of the following to look at. If you like them, you may be able to find them on
www.half.com or a similar place:
A Veterinary Guide for Animal Owners by C. E. Spaulding, D.V.M. Probably the best of the lot.
Keeping Livestock Healthy: A Veterinary Guide by N. Bruce Haynes, D.V.M. Also good.
Herbal Handbook for Farm & Stable by Juliette de Bairacli Levy.
A Veterinary Guide for Farmers by G. W. Stamm.
Caring for Livestock: A Veterinary Handbook by Jaime Isaac Reibel.
If you specialize in one breed then those by Interstate Press may be of interest. Most are authority by M.E. Ensminger or his son. Examples are Beef Cattle Science, Swine Science, Sheep & Gaot Science, etc. These are written in textbook form.
