There are several tools available for cow/calf producers that can lead to a decrease in one of the primary problems seen in neonatal calves – diarrhea. Diarrhea is a leading cause of mortality in baby calves and has many causes.

As I begin writing this, the weather report is showing continued cold weather and some possibility for frozen precipitation. Winter season is upon us. By the time you read this, you have already turned bulls out to breed your fall herd, your spring calves are either already sold or waiting January markets, and your family is getting prepared for Christmas celebrations. But there are several things that livestock owners have to consider to maintain animal health during this time of year.

It is the time of year when cattle are seen rubbing on trees, fence post, feeders or anything they can. They will rub until the skin becomes raw, thick and irritated and often the cause for this is lice. It costs cattle producers millions of dollars in losses each year. They are biting the lice, which live on their skin and hair. These are a sucking lice. Sucking lice tend to cause anemia, which will cause the immune system to become weaker leading to other illnesses. The lice will cause a decrease in weight gain and in milk production, and this will lead to an increase in feed costs and cause you to treat other issues resulting in less profit.

Warts are a common condition seen in cattle, which for the most part is a nuisance. But in sever cases warts may cause other problems, like secondary bacterial infections, which may lead to unthriftiness. Many say warts are due to compromised immune systems or poor nutrition, that may be so, but most cases I see are in fat, slick show animals. I see these animals because they cannot be shown or sold if warts are visible. In some of these cases, depending on the severity, we can surgically remove or freeze the warts. This allows the animals to recover from the problem at a faster rate, allowing a quicker return to the show or sale ring.

Testing for persistent infected bovine viral diarrhea in cattle can be beneficial.

While dealing with the ice and cold weather I have noticed our nutrition gurus are looking more and more into balancing rations of essential amino acids instead of protein. I ask the question “Is their requirement of protein for animals in their diet?” Actually “NO.” Animals must have the 10 essential amino acids and cats require 11 amino acids.

This is the time of year many area farmers are calving. Usually this time of year is not as cold as it has been this year. The weather definitely presents difficulties we don’t have when we calve in later spring and fall.

My practice has several small ruminant herds in it. We see a few cases each year of Caprine Arthritis Encephalitis (CAE) or Infectious Leukoencephalomyelitis. This disease is devastating to the animal it affects. CAE is usually seen in young goats. The most important thing to remember is there are no effective treatments for CAE. Prevention is the only way to control this syndrome.

Each year producers have lost several dollars in profit, either by loosing calves or in the expense of treating calves that have diarrhea problems. These problems can be in most cases prevented with good management practices. Calf diarrhea may be caused by bacteria, viral or poor nutrition.
