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.

With the first frost of the year right around the corner, fall poses an excellent time of year to discuss the Bot fly, its impact on the horse and best means of control.

Recent weather conditions have raised several health problems for cattle producers. One of the most dramatic changes has been an increase in mastitis cases on dairy farms. Mastitis can be devastating to the economic well-being of a dairy operation, and successful treatment and control measures are needed to ensure financial stability, especially in the current economic environment.

In this day and age significant concern has developed over the use of pharmaceuticals in animals intended for human consumption. Amongst consumers, there are many varying opinions regarding the use of drugs and chemicals in food animals ranging from those that prefer organically produced products to those that give little concern over the matter.

Show season is upon us again. Remember show animals are exposed to more diseases as they are co-mingled with others. Vaccinations of these show animals are a must. Consult your veterinarian as to which vaccines are recommended.

The wet weather we have been dealing with for most of this year has brought with it several challenges for livestock producers throughout southwest Missouri. Wet and cold weather led to increased calf losses early this year, and wet fields have not allowed farmers to harvest hay crops that appear plentiful to the average person driving down the road. But I have observed another problem this year affecting horses and cattle. While I don’t have scientific proof or hard statistics to prove my theory, it is my opinion that I have had a number of cases where the problem seemed to stem from access to tall fescue, and I am concerned that fescue toxicosis could be a significant problem this year.

Urolithiasis is a common condition in goats and typically affects young wethers. It is characterized by small, crystallized stones (urinary calculi) forming in the urine which then settle out in the bladder and cause disease when they obstruct the outflow of the urethra and render the animal unable to urinate. This condition is of major significance due simply to the fact that it can make animals very sick very quickly and often results in death if not effectively treated soon enough.

Over the past several weeks I have had numerous questions regarding the safety of Johnson grass as a forage or for hay. The extremely, hot and dry summer left many pastures short and several producers feeding hay as we approach fall. Johnson grass is a plant that tends to grow and proliferate during periods of heat and drought when other grasses fail to grow. As a result many pastures have an abundance of Johnson grass this year in comparison to other forages and during periods when feedstuffs are in short supply, producers naturally consider grazing or haying the Johnson grass. However, under the right conditions Johnson grass can accumulate high levels of nitrate and/or prussic acid and become highly toxic to livestock.

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.

Over the past several months, I have examined several beef cows that presented with chronic weight loss and diarrhea. Based on clinical findings, I decided to test several for Johne’s disease, and found cows from four separate farms that tested positive for the disease.
