Recognizing Sick Livestock

What are the first signs a farm animal is sick?

The earliest signs are usually changes in behavior rather than anything dramatic. An animal that lags behind the group, stands with its head low, ignores feed it normally rushes to, or isolates itself is telling you something. Dull eyes, a rough or staring coat, droopy ears and a hunched back are common clues.

Livestock are prey animals, and instinct tells them to look healthy as long as possible. By the time an animal looks obviously sick, the problem has often been building for a while. That is why a consistent daily look matters more than any single skill.

How do I observe an animal before touching it?

Watch from a distance for a couple of minutes while the animal does not know you are looking. Note how it stands, walks and breathes, whether it is eating or chewing cud, and how it behaves compared with its herdmates.

Then approach calmly and look at the face, eyes, nose, mouth, belly, legs and hind end. Note anything unusual and where you found it. Handling a sick animal roughly can make it worse, and handling a sick animal before healthy ones can spread illness, so do your sick checks last.

• Posture and movement: limping, stiffness, circling, standing alone
• Appetite and thirst: off feed, not drinking, or drinking far more than usual
• Eyes and nose: discharge, cloudiness, crusting
• Breathing: fast, noisy, labored or with the mouth open
• Manure and urine: loose, bloody, very dry, or none at all
• Belly shape: swollen on the left or unusually tucked up

What are the vital signs, and should I learn them?

Temperature, heart rate and breathing rate are the basic vital signs, and normal ranges differ by species and age. Learning how to take them, and knowing your own animals' resting numbers, gives a vet something concrete to work with on the phone.

Do not rely on numbers you find in a random place. Ask your veterinarian to show you how to take a temperature safely and what is normal for your species, and write those ranges down. Practice when animals are healthy so you are not learning in an emergency.

Which signs mean call the vet right away?

Some signs are never worth waiting on. An animal that cannot stand, is down and not getting up, struggles to breathe, shows a swollen belly with obvious discomfort, has trouble giving birth, has seizures, collapses, or has a severe injury needs a veterinarian immediately.

Several sick animals at once, or sudden deaths with no warning, are also reasons to call right away. Do not move other animals on or off the farm until you have spoken with your vet, and ask about reporting requirements, since rules on reportable diseases differ by state and species.

What should I write down before I call?

A vet can help far more when you give clear information. Have the animal's species, age, sex, and identification ready, along with how long you have noticed changes, whether it is eating and drinking, what its manure looks like, and any recent changes in feed, pasture, weather or new animals.

If you know how to take the temperature, give that number. If not, describe what you see rather than guessing at a diagnosis. Phone photos or a short video of the animal walking or breathing can be very useful.

What should I do while waiting for the vet?

Separate the animal from the group in a clean, quiet, sheltered spot with fresh water and shade or warmth as the weather requires. Keep stress low. Do not give medicines, home remedies or drenches unless the veterinarian tells you to, since the wrong thing can do harm.

Wash your hands and boots after handling, clean anything that touched the animal, and tend healthy animals first from then on. Write down times and what you observe so you can pass the details along.

How can I get better at noticing small changes?

Skill comes from repetition. Spend a few minutes each day simply watching your animals do nothing special. Over weeks you will notice who sleeps where, who drinks when and how each animal breathes at rest. That quiet baseline is worth more than any checklist.

Photographs help too. A picture of each animal in good condition, taken from the side and the rear every month, lets you compare body shape and coat over time, when day-to-day changes are too gradual to see. Ask your vet or an experienced keeper to look over your animals once so that you can calibrate what you see against a trained eye.

• Watch for ten quiet minutes before chores
• Take monthly photos from the side and the rear
• Write down odd behavior with the date
• Ask an experienced keeper to compare notes
