I had this book PMed tyo me. I looked on Amazon and seemd to be something good aqnd helpful.
The Cattle Health Handbook by Heather Smith Thomas. It is more about diseases & treatments etc.. It may be a good reference guide for the "field". Especially considering there aren't any veterinary people readily available.
I had this sent to me by a helpful gurl... there are a bazillion websites on google about cattle.
