Scours in calves

Scours is a common illness in young calves. Understand the causes and effects of this disease to treat and prevent it

By
Scours can be caused by certain kinds of bacteria, viruses or protozoa, but other factors come into play as well. “It’s often the interaction between the immune system, the environment and the pathogen load. The old saying is that the solution to pollution is dilution (or) minimizing the pathogen load,” says Dr. Paul Hardes, a […] Read more
Most cases of scours in calves occur at three days or older, meaning they are most likely viral in origin so electrolytes will do more good than antibiotics.

Factors that hinder calf immunity

Calving Health with Heather Smith Thomas

By
Illness occurs when an animal’s body is overwhelmed by infection. A healthy animal with strong immunity is less likely to become sick than an animal with poor immunity. Immunity refers to the body’s ability to fight off pathogens, and this ability is developed in a complex process in which the body creates specific weapons for […] Read more

A simple vigour test for newborns

Give it two fingers to suck… that’s step one

By
Two simple observations at birth can tell you whether a newborn calf has the vigour to quickly suckle enough colostrum to achieve the protection of passive immunity. “Measuring calving ease and suckle reflex is a quick and easy method to identify beef calves that are unlikely to consume colostrum by four hours after birth,” says […] Read more

Intranasal vaccines get around maternal antibodies

Animal Health: Maternal antibodies unpredictable


By
Calves are born without fully functioning immune systems, making them reliant on passive immunity from maternal antibodies for disease protection. As a result, we assumed for a long time that vaccinating calves at an early age was a complete waste of time and money as the maternal antibodies would attack any pathogens introduced in the […] Read more
Vet advice

Doin’ what needs doin’: Part 1

A wise old farmer once advised me, “Do what needs doin’, scratch what needs scratch’in. A good piece of advice as we look ahead to calving season and the grazing season beyond. Being sure cows and bred heifers are fed properly through winter and later stages of pregnancy tops the list. Do this well and […] Read more

Monitoring the suckle reflex in calves

By
Some recent research has revealed a test that easily predicts which calves should receive supplemental colostrum at only a few minutes old. It was the result of some work by Dr. Elizabeth Homerosky, a veterinarian at the faculty of veterinary medicine at the University of Calgary, as she was comparing various testing procedures to determine […] Read more

Get ready for calving

By
Another list you might say. Seems important things tendered as advice always come in a list; some is trivia, some make sense, others simply repeat what’s been said before. The following is a bit of all three, but needs to be offered as a reminder each calving season. Hang this one by the door and […] Read more
