CATTLE & SWINE · PREVENTIVE CARE

Cattle & swine health
starts before illness.

Client-focused foundations for observation, nutrition, biosecurity, diagnostics, heat safety, pain recognition and veterinary planning in cattle and pigs.

GROUPS CHANGE THE PICTURE

Health decisions must consider the individual, the group and food-animal requirements.

VMX 2026 large-animal sessions emphasized careful physical examination, respiratory and neurologic disease, diagnostics, welfare and the practical realities of treating cattle and swine.

Look for change before handling

  • Reduced feed or water intake and altered rumination in cattle
  • Coughing, increased breathing effort, nasal discharge or animals falling behind
  • Lameness, reluctance to rise, arched posture or isolation
  • Diarrhea, constipation, blood or sudden manure changes
  • Skin lesions, scratching, swelling or wounds
  • Changes in growth, milk, reproduction or group behavior

Use species-specific expectations

AreaCattlePigs
Digestive systemRuminants; cud chewing and rumen function are key observations.Single-stomached omnivores; ration balance and abrupt feed changes matter.
Heat behaviorSeek shade, pant and reduce intake; dark or heavy animals may be affected sooner.Cannot sweat effectively; open-mouth breathing and piling are dangerous signs.
Feet and movementHoof overgrowth, sole disease and joint problems can reduce feed access.Foot, joint and floor-related injuries may appear as reluctance to rise or shortened steps.
Social signsA sick animal may lag, isolate or stop ruminating.A sick pig may isolate, dog-sit, hunch or become reluctant to compete.

Match the program to the operation

  • Maintain a veterinary-client-patient relationship and written protocols.
  • Select vaccines for species, age, use, location, source and disease pressure.
  • Review nutrition, water testing, minerals and body-condition or growth monitoring.
  • Base parasite and external-pest control on diagnosis and risk.
  • Inspect feet, flooring, housing, ventilation, bedding, shade and cooling systems.
  • Plan reproduction, calving or farrowing, colostrum and newborn processing before the due date.

Management failures often look like medical disease

  • Keep feed consistent, protected from moisture, rodents and wildlife and appropriate to species and production stage.
  • Provide enough feeder and waterer access for low-ranking animals; confirm flow rather than only looking at the tank.
  • Change rations gradually and contact the veterinarian for bloat, acidosis, off-feed groups or suspected contamination.
  • Provide dry resting space, nonslip footing and room to stand and lie normally.
  • Use ventilation to control humidity, gases and airborne particles without creating harmful drafts on young animals.

Prepare before the forecast becomes dangerous

  • Ensure shade and multiple reliable water points before hot weather.
  • Schedule handling, transport and feeding for cooler periods when possible.
  • Use fans, ventilation, sprinkling or other cooling methods designed for the species and facility.
  • Watch pigs closely because they dissipate heat poorly and can deteriorate rapidly.
  • Provide wind protection, dry bedding and adequate energy during severe cold while maintaining ventilation.

Do not move a mystery through the herd

  • Isolate new, returning and sick animals with dedicated equipment.
  • Record temperatures, signs, treatments, deaths and movements.
  • Use veterinarian-directed testing such as fecal examination, culture, polymerase chain reaction, serology or necropsy when indicated.
  • Preserve diagnostic value by calling before disposing of a freshly deceased animal.
  • Work with the veterinarian before shows, sales or transport when contagious disease is possible.

A pet pig still needs livestock-informed care

  • Provide a measured complete diet rather than free-choice grain, dog food or unrestricted treats.
  • Use rooting, foraging and training enrichment while preventing access to garbage, medications and toxic plants.
  • Plan hoof and tusk evaluation, skin care, vaccination and parasite testing with a pig-experienced veterinarian.
  • Teach crate, trailer and handling skills before an emergency.
  • Check local zoning, identification and movement requirements even when the pig is a household companion.

Emergency signs in cattle and pigs

  • Severe breathing difficulty, blue discoloration or collapse
  • A rapidly swollen left abdomen in cattle, choking or inability to swallow
  • Neurologic signs, circling, seizures or inability to stand
  • Heat stress with open-mouth breathing, weakness or animals piling
  • Prolonged labor, severe bleeding, prolapse or a compromised newborn
  • Sudden group illness, multiple deaths or suspected toxic exposure
Important: Cattle and pigs are food-producing animals even when kept as companions. Use only veterinarian-directed medications and record dose, route, animal identification and withdrawal interval.
