When to Call a Large Animal Veterinarian

A large animal veterinarian does more than treat sick animals. For cattle, horses, sheep, goats, pigs, and other livestock, good veterinary care supports daily comfort, herd productivity, food safety, and long-term health. In rural Western Colorado, veterinary care must also work around weather, long distances, calving season, handling facilities, and practical budgets.

​When to Call a Large Animal Veterinarian
Some situations require prompt attention. A horse showing severe colic signs, a cow struggling to calve, a down animal, or a newborn that will not nurse may need immediate veterinary care. Calling early can provide more treatment options and improve the animal's chances of recovery. Other concerns may be less urgent but still deserve attention. Sudden changes in feed intake, persistent coughing, ongoing lameness, poor weight gain, or diarrhea affecting several animals can signal a larger herd-health problem. Before calling, gather useful information such as the animal's age, species, symptoms, temperature if safely obtained, recent feed changes, vaccination history, medications, breeding status, and how many animals are affected. Photos or short videos can also help.

What Happens During a Farm Call
Farm-call medicine is practical medicine. A veterinarian considers the animal, available facilities, weather, equipment, and the owner's observations.
An examination may include checking temperature, hydration, heart and lung sounds, rumen activity, body condition, movement, eyes, mouth, skin, udder health, or reproductive status. Depending on the situation, the veterinarian may collect blood, fecal, or milk samples, perform a pregnancy check, treat an individual animal, or evaluate the larger group. Treatment may involve medication, diagnostic testing, or changes to nutrition, bedding, parasite control, stocking density, or management practices. For food animals, veterinarians should also discuss medication withdrawal times and the importance of accurate treatment records.

Preventive and Herd Health
Preventive care is different for every operation. Vaccination, parasite control, nutrition, reproductive management, hoof and dental care, and biosecurity should reflect the species, age, production goals, local risks, and health history of the animals. Fecal testing, for example, can help determine when parasite treatment is actually needed rather than relying on an automatic schedule. The same principle applies to vaccines and supplements: more is not always better. A veterinarian can help build a plan based on actual risk. One sick animal can also reveal a larger problem. Calf diarrhea may raise questions about colostrum and sanitation. Repeated lameness may point to footing or nutrition. Poor conception rates or weak newborns may indicate reproductive or disease concerns.

Prepare for Emergencies
Keep your veterinarian's phone number available and make sure family members or employees know who can make treatment decisions. Ask your veterinarian what first-aid supplies and medications are appropriate to keep on hand. Plan for transport, too. Some animals require hospital-level diagnostics or surgery, while others can be treated more effectively and comfortably during a farm visit.

Care That Fits Your Operation
Veterinary care works best as a partnership. Owners know their animals and daily operations; veterinarians bring medical training, diagnostic judgment, and experience with herd health. At Plateau Valley Animal Hospital, large-animal care is built around that partnership, from routine herd-health visits and reproductive care to horse examinations and urgent farm calls. If something about your animals feels off, trust your observation. A timely conversation with a large animal veterinarian can provide reassurance, a practical next step, or treatment before a small problem becomes a larger burden.
