Be prepared for an animal disease outbreak

Hopefully, infectious diseases don’t appear in Canada but the industry needs to have a plan in place

Hopefully, infectious diseases don’t appear in Canada but the industry needs to have a plan in place

If there ever is a foreign animal disease outbreak in Canada, we all know it could be devastating to the industry. Contagious pathogens such as foot and mouth in bovines, sheep and swine, or African Swine Fever (ASF) in pigs, can cost individual producers in lost production and animal deaths, as well as closing the […] Read more

'It is important for producers to encourage and work with female vets… I have met many that can definitely do anything that I did in practice.' – Roy Lewis.

Creative ideas on accessing veterinary care

Animal Health: A few thoughts on how producers can perhaps help fewer veterinarians reach more animals

With a lot of talk about the shortage of veterinarians, especially large-animal practitioners but also small-animal and emergency veterinarians, steps are being taken to increase veterinary school graduates. It was recently announced that the University of Calgary vet school will expand from the current 50 students as of two years ago to 100 students within […] Read more


Understanding bull EPDs is important when making selection decisions, and Roy Lewis asks if there should be some adjustments made to scrotal circumference measurements.

A few key points on producing livestock

Animal Health with Roy Lewis: A mixed bag of things to consider, and important topics to discuss with your local vet

With my training and experience as a veterinary practice owner, later in the pharmaceutical industry and also as a beef producer myself, I question things from several different angles. If there is a more practical, safe or cost-effective way of doing things, that’s the road I take. When veterinarians give advice. it’s also important that […] Read more

Having two or even three  esophageal feeding tubes on hand and used during calving season is an effective way to ensure calves are supplied with key nutrients and other products when they are needed.

An esophageal feeder is a key tool in saving calves

Animal Health with Roy Lewis: It is an effective way to administer a range of products to newborn or sick animals

Modern tool boxes in cow-calf production would not be complete without preferably at least two esophageal feeding tubes. These relatively simple, multipurpose feeding tools allow a safe, convenient method to give things such as colostrum or colostrum replacers, electrolytes, milk replacers and a few other treatments to calves. No producer should feel they don’t know […] Read more


When pulling a calf, once you snug the chains up make sure the tail is down and there is enough room.

Tips for delivering a backwards calf

Animal Health with Roy Lewis: If one calf presents backwards, there is a good chance there may be another

With improved breeding practices nowadays, calving season is more about mothering up, colostrum consumption and keeping calves warm and dry. Cases of calving difficulty have been greatly reduced. However, the backwards calf is still the most common calving malpresentation that require some intervention. With the alignment of the calf and the way the feet are […] Read more

Once a calf gets weak and gets down or has no suckle reflex, it needs IV fluid.

Important scour-prevention tips for calves

Keep calving facilities clean, and focus on good herd health status

Scours is the number-one killer of calves under two months of age. It takes many different management strategies to prevent scours and it is important to know that it is caused by many different things. The following points will offer some ideas to reduce the buildup of organisms and increase resistance in your calves. Disease […] Read more


bulls in pen

Managing the stifled cow or bull

Animal Health with Roy Lewis: A condition that can be treated, but culling may also be best option

A stifle condition is more commonly seen in older cows and in bulls that suffer breeding injuries. Many of these lamenesses are probably diagnosed incorrectly and in many cases treated inappropriately, often resulting in an animals being kept too long. When we talk about a stifled cow or bull, we refer to injury to ligaments […] Read more

If you haven’t implemented an implant program into your operation, think of doing it now.

Important to follow proper implanting technique for calves

Growth implants can generate at least a 15:1 return on investment

After all these years, implanting is still one of the most underutilized management tools in beef production. The feedlot sector has pretty much adopted implanting routinely, but the cow-calf sector lags far behind. It is one thing if “natural, hormone-free, or organic” beef is being raised and implants must be avoided as part of these […] Read more


We all need to be the voice of reason and take the emotional arguments out of these discussions especially when it involves those who don’t know the vaccine science issues. – Roy Lewis.

Producers need to be the voice of reason for vaccines

Roy Lewis: Animal health products are not intended for humans

In my view, cattle producers can be the voice of reason when it comes to helping the non-rural population understand the decisions about vaccine efficacy, safety, and adverse reactions the rare time it happens in their own cattle. All the discussions and debate about COVID vaccinations revolve around a few questions — whether to vaccinate, […] Read more

A single lightening strike that travelled along the fence line is believed responsible for the death of these cattle.

Livestock electrocution can be natural or man-made

Animal Health: Make sure tools and electrical services are properly installed and maintained

We’ve all seen pictures and heard of the cattle deaths following severe lightning storms. Cattle are susceptible because they are so well-grounded. They often gather along fence lines or under tall trees, seeking shelter when lightning strikes. There really is no prevention for this other than to make sure all fences, especially electric fences, are […] Read more
