IBR is a serious cause of abortion in beef cattle

Veterinary Case Study: After buying new stock, a rancher’s cow herd starts aborting third-trimester calves

Early one morning in January, Alf called upset over what he found when checking his herd of purebred Herefords. Lying in the straw were three aborted fetuses and two other cows appeared to be in the process of aborting third-trimester fetuses. Alf, an excellent stockman but very worried, asked the hard question of what might […] Read more

Preparing for calving season

Veterinary Case Study: Dr. Clarke coaches a beef producer who has purchased 50 first-calf heifers right before calving season

Jim came into the clinic one day. He’d even called ahead to say he needed a few minutes of my time to talk about the 50 new heifers he bought and what they might need to help them through calving season without problems. Jim had become an astute cattleman through the years, always trying to […] Read more


A cow disposes of the afterbirth as two young calves lay nearby. Newborn calves are vulnerable to disease, so farmers and ranchers should strive to reduce disease risk during calving season.

Reducing disease risk from calving season onwards

Whether it’s scours or Johne’s disease, farmers and ranchers can reduce the chance of transmitting it

With winter calving almost at a close, grassland producers are preparing for their own spring calving season. Chad Ross calves his herd of 800 to 1,100 cows as close to nature as he can. The owner and operator of L-7 Land and Cattle at Estevan, Sask., switched to grassland calving in the mid-2000s. Unless a […] Read more

Causes and risk factors of abortion in cattle

Vet Advice with Dr. Ron Clarke

When examining abortion in cattle, it’s important to look at incidence, cause, definition, when to summon help and what to do. As an aid to producers, abortion can be defined as terminating pregnancy any time after around 42 days, when placentation is complete. Placentation is the establishment of membranes joining mother and fetal blood supply […] Read more

DNA samples at calving could be new norm

Alberta cattle producer says it’s time for the beef industry to catch up

For seed stock producers, taking DNA samples from newborn calves is becoming more common. Most seed stock herds calve in the winter when the temperature can dip to around -30 C or beyond, snow sparkling under a harsh winter sun. At that time of year, there is already so much to do, and adding another […] Read more

Cameras make a difference in winter calving

Winter calving can be a challenge, but cameras make it easier

Winter is here in full force, and freezing temperatures, large dumps of snow and short days can make winter calving a challenge for seed stock producers. However, technologies such as calving cameras can help make it much easier by saving time and labour. For many, it has become a necessary tool on their operations. Winter […] Read more


Ideally, a cow’s body condition score should be evaluated and corrected right after weaning, as that is the period of lowest nutrient requirement.

Post-calving nutrition to maximize conception rates

Evaluating body condition score can be difficult and requires training

With the current price of calves, targeting high pregnancy rates should be a priority on any cow-calf operation. In addition to remaining pregnant, they must conceive early in the breeding season to maintain a 365-day calving interval and ensure a uniform calf crop. This will promote better returns for the weaned calves and profitability for […] Read more

Two calves on pasture. The Sandhills system works by lowering the pathogen load newborn calves are exposed to on calving grounds.

Shifting to the Sandhills calving system to cut scours in young beef calves

While it’s not for every operation, the Sandhills calving system can reduce diarrhea in young calves 

Cow-calf producers across North America face wide-ranging challenges each calving season but scours and neonatal diarrhea often top the list. Various systems are used to help prevent what can become devastating losses when these pathogens gain a foothold.  An established approach still growing in popularity is the Sandhills calving system, designed to separate newborns and […] Read more
