Organic Valley farmer members have access to two veterinarians on our cooperative's staff.
Dr. Paul Dettloff has worked with CROPP Cooperative to ensure healthy livestock since 2002. His Arcadia, Wis., large-animal practice has become the home base of an internationally recognized organic herd health expert.
In 1988, after 20 years serving conventional farmers, “Doc” Dettloff’s observations led to his interest in organic methods. Since then, Dettloff has dedicated himself to sustainable and organic/biological treatment for dairy and beef cattle, sheep and goats. He has researched and developed treatment protocols for many natural remedies, botanicals and homeopathic medicines.
At CROPP Cooperative, Dettloff consults with more than 1,000 member farmers across the United States in person and over the phone. He also trains field personnel, attends regional educational meetings and conducts a yearly hands-on veterinary workshop to educate farmers and conventional veterinarians on organic livestock care practices. He emphasizes healthy soil as the foundation for healthy animals and advises not giving animals anything people wouldn’t give themselves.
Dettloff is committed to sharing his vast array of knowledge with others. He parlayed the tinctures and botanicals he developed into Dr. Paul’s Lab brand herd health products and co-founded Crystal Creek, a natural veterinary supply and remedy provider. Dettloff is also a consultant for Lancaster Ag Products in Ronks, Pa., and Essential Water Solution in Story City, Iowa. He authored Alternative Treatments for Ruminant Animals and has written several CROPP Cooperative Organic Farming Technical Bulletins, covering topics from stray currents to natural mastitis treatments.
Dr. Jodarski has worked with CROPP Cooperative to maintain and improve animal health on our 1,300 member farms since 2007. Belief that organics was a more sustainable way to run a farm led him to the field.
In practice since 1987, Dr. Jodarski was an owner/partner in a central Wisconsin large animal practice for 12 years. He then was a consultant for an international cattle breeding company and later worked as a staff veterinarian for two companies that supply nutritional supplements and livestock health aids for organic and sustainable farmers.
At CROPP Cooperative, Dr. Jodarski focuses on organic and sustainable livestock practices. In addition to consulting with CROPP Cooperative livestock farmers across the United States, Jodarski trains field personnel, attends regional educational meetings and gives presentations on how to keep food animals healthy without the use of antibiotics, synthetic hormones and chemicals.
Dr. Jodarksi recently co-authored his first CROPP Cooperative Organic Farming Technical Bulletin, and is a regular contributor to the cooperative’s member newsletter, The CROPP Forum, on herd health matters.
Dr. Hubert Karreman has worked on dairy farms and with dairy cows since the early 1980's, first as a soil conservationist during college, then as a herdsman for 6 years, and now as a veterinarian since his graduation from the University of Pennsylvania veterinary school in 1995. He began studying herbs in 1984 and started using natural treatments with cows in 1988 when he was a herdsman on a Biodynamic farm. He works exclusively with certified organic dairy farmers and focuses on internal medicine and infertility issues.
He is an internationally recognized expert in the non-antibiotic treatment of infectious disease and enjoys interacting with medical doctors and veterinary researchers in developing hyper-immune plasma, hyper-immune colostrum and botanical treatments. He has given numerous invited talks about natural cattle care to farmers, veterinary associations and veterinary schools in the US, Canada, Holland and South Korea. He has participated in far reaching policy groups such as the USDA National Organic Standards Board, and AVMA Taskforce for Complementary and Alternative Veterinary Medicine. He has also written two books, "Treating Dairy Cows Naturally: Thoughts and Strategies" and "The Barn Guide to Treating Dairy Cows Naturally".
Dr. Karreman is president of the Veterinary Botanical Medical Association, is certified in veterinary botanical medicine, and also completed the acupuncture course given by the International Veterinary Acupuncture Society. He has a soft spot for homeopathy as it worked extremely well for him as a herdsman. He is especially thankful for the gift of empathic and intuitive sensing when being with animals.
