If you’re a livestock farmer, you’ve likely faced one of the most frustrating situations on the farm: a sick or distressed animal. You feel helpless, unsure of how to provide assistance or relief.
According to Dr. Rob Swackhammer, veterinarian with Upper Grand Veterinary Services in Guelph, Ont., who specializes in large animal veterinary care, these situations can often be managed with a little common sense and confidence.
“Having the basic skills and self-confidence to assist an animal that’s uncomfortable not only improves the animal’s welfare but can be the difference between calling the vet or not, or even buying time until the vet arrives,” says Swackhammer. Knowing what to look for and how to manage an animal health situation can also provide a veterinarian with valuable information to make timely decisions.

A firm believer in lifelong learning, Swackhammer often works with clients to educate them on early symptoms and signs of animal illness or distress. He shares his practical on-farm approach with farmers to identify common issues, how to manage emergency situations and when to call in a veterinarian for help.
Here are the top four animal health concerns Swackhammer believes livestock farmers should be able to identify and know what to do if faced with the situation.
1. Dystocia
Commonly known as an abnormal or difficult birth, dystocia can occur at any stage of labour, in all types of livestock and at any age.
Swackhammer advises farmers to brush up on the stages of labour based on the type of animal they have. For example, the first stages of labour in a cow could take up to five hours, and once feet are presented the calf should be born within the hour. Understanding the labour stages can help farmers understand if the situation is prolonged or problematic, and if they need to call a veterinarian for help.
If an animal’s labour becomes prolonged or it exhibits signs of discomfort, Swackhammer advises farmers to perform an internal examination. “The ability to properly assess an animal, like checking on the position of the baby, can help everyone make informed decisions. If a vet needs to be called, the ability to provide as much information over the phone about the length of labour and position of the baby inside the mother will benefit everyone, especially the animal in distress,” says Swackhammer.
“If labour is going well and progressing there is no need to touch the animal,” Swackhammer reminds farmers. “But knowing when to step in can save the baby and result in a healthier mother.”
Of course, mitigating dystocia can be managed even before the animal becomes pregnant, by selecting sires that offer calving, lambing, foaling or kidding ease and proper nutrition to maintain ideal animal body weight and animal condition before and during pregnancy.
Swackhammer recommends pregnancy checks or ultrasounds to identify the accurate birth timing and determine if the animal is carrying multiples. He reminds farmers that the more information you know ahead of time, the better prepared you can be.
When it comes to being prepared, having the right supplies on hand is a must. These should include OB gloves and lube, clean rope, anti-inflammatory medication, needles and syringes, and colostrum.
Swackhammer reminds farmers that wearing personal protection when assisting with livestock births is important because some zoonotic diseases can be transmitted to humans.
A clean and dry environment where animals can be caught easily and restrained, if necessary, should also be prepared to reduce stress on the animals and farm workers.
2. Scours
Scours refers to diarrhea and is most common in young animals, such as calves, lambs, piglets, kids and foals. It’s a common and potentially serious condition that can lead to dehydration, weakness and even death if not treated promptly.
According to Swackhammer, the best defence against scours is colostrum. Ideally, every newborn animal should drink colostrum within eight hours of birth to reduce the risk of scours. Young animals should also have access to plenty of clean water to supplement their hydration.
Watery, loose feces are the most common signs of scours. Young animals can also show signs of dehydration, such as sunken eyes and a dry mouth or nose. They can also be lethargic and show little interest in nursing, drinking or eating.
Early intervention is key to managing scours. As soon as signs are detected, the animals should be quarantined to reduce the transmission of pathogens to other young animals. If the animals are on pasture, Swackhammer advises farmers to rotate pastures and isolate sick animals to reduce pathogen buildup in the animals’ environment.
Early treatment can be as simple as supplementing the young animal’s hydration with oral electrolytes once or twice a day. Electrolytes can be easily fed with a bottle and, as an added benefit, can help reduce the risk of acidosis in young animals. Swackhammer reminds farmers to read and follow label directions when administering all medication, including electrolytes. Providing an anti-inflammatory can also help young animals recover faster and keep them comfortable.
Swackhammer says it’s time to call the veterinarian when more severe signs of dehydration and lethargy are visible, or if the animal doesn’t respond to electrolytes. He explains that more severe stages of scours can be identified by drooping ears, sunken or glazed eyes, or if the young animal has difficulty standing.
“That’s when you really need to call your vet,” he says, reminding farmers to keep detailed records of the illness timeline and any medication they have administered to provide the veterinarian with the most accurate and timely information.
If a herd or flock is prone to scours, Swackhammer advises farmers to consult with their veterinarian about preventative vaccine programs for mature animals that can help reduce the risk when young animals are born.
3. Lameness
Lameness is a frequent issue in livestock and, according to Swackhammer, the most common cause is foot rot. This is especially prominent during the muddy seasons of spring and fall, and that’s why he reminds farmers that prevention starts with keeping a clean and dry environment for livestock.
“Lameness due to foot rot can look like a broken foot, too,” says Swackhammer, noting that other common signs include swelling and an animal’s inability to bear weight on the foot.
On-farm treatments can start with a long-acting antibiotic that should show signs of improvement within two days. Administering an anti-inflammatory is also recommended to reduce swelling and improve recovery time.
If the animal doesn’t respond to treatment, or doesn’t improve within two days, Swackhammer recommends calling a veterinarian for a consultation. He says that in prolonged cases, it’s best to seek professional medical care to determine the cause and best course of treatment.
4. Respiratory infections
“Pneumonia is the predominant respiratory illness in livestock, especially in young animals,” says Swackhammer. He says that once again colostrum is a young animal’s best defense, along with a clean, dry and well-ventilated environment.
Signs of pneumonia in young animals can vary, but common symptoms include coughing, laboured or rapid breathing, nasal discharge, fever and lethargy. Swackhammer says that in cases of respiratory illness, he recommends calling a veterinarian if any of these signs appear, especially if an animal is open-mouth breathing.
Having a thermometer on hand to monitor the animal’s temperature is the first step to managing pneumonia. He says the first line of treatment will likely be a long-acting antibiotic, but that should be directed by a professional. And if there’s no response to treatment within 24-48 hours, then a second call to the veterinarian is recommended.
Infected animals should also be quarantined, and nose-to-nose contact with other animals should be restricted or prevented altogether.
To help prevent pneumonia, farmers can start by minimizing stress in young animals. “Stress weakens an animal’s immune system and increases their risk of picking up bacteria and infections, especially respiratory infections,” explains Swackhammer.
Some of the most stressful periods in a young animal’s life can be weaning and transportation. Swackhammer advises farmers to consider a pre-weaning vaccination program to reduce the risk of illness and a weaning program that reduces animal stress. These management considerations can also help manage stress and boost immunity during transportation, reducing the risk of “shipping fever,” a common term for respiratory illness in livestock.
Empowering farmers
“Farmers are resourceful and intuitive, they just need to feel empowered sometimes, and have the proper tools and skill set to take action,” says Swackhammer, who recommends that farmers consult with their veterinarian to learn more about these common illnesses and what they can do to prevent and manage them on their own farm.
