In the last issue we discussed pinkeye as a major cause of disease in cattle during the summer months. Another problem that frequently presents itself in my chute during the summer is foot rot. I have seen numerous cases of foot rot in cattle this summer already. The disease is caused primarily by a bacterium called Fusobacterium necrophorum and is a significant cause of lameness in cattle – beef and dairy alike. Like pinkeye, mortality from the disease is generally absent but morbidity can get high with up to 25 percent of the herd affected in severe outbreaks. Foot rot can be a significant source of lost production. Cows that are lame from foot rot tend to lie around, eat less and produce less milk. Whether that milk is going into the bulk tank or into the calf, less milk means less money to the producer. Additionally, treatment costs and the occasional animal with unresolving lameness represent further economic loss due to the disease.

As I prepare this column, it would appear there is at least a small reprieve from some of the economic gloom and doom of the past 6 months.  Now I understand that this does not take away from the fact that everyone’s input costs have jumped drastically over the past couple of years.  But it should get you to thinking of ways to maximize your production and more efficiently use your resources.

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

This time of the year it is common to see cows standing in the shade and wading in ponds in an effort to find relief from the heat. Unfortunately, the summer sun is not the only factor affecting heat stress on cattle grazing Southwest Missouri pastures.

Recently in southwest Missouri we have seen an increase in number of herds affected with Trichomoniasis. This disease is a reproductive nightmare. It can be devastating to the owner. Reducing the calf crop and eliminating any significant income for that herd.

As spring approaches, many goat producers are preparing for the beginning of kidding season. One condition that producers may encounter as does enter their last trimester of pregnancy and near parturition (birthing) is ‘pregnancy toxemia’. This can be a life-threatening condition for some does and early recognition of this disease is paramount to providing successful treatment. This very same condition is also seen in sheep with similar clinical signs and treatment options.

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.

Pneumonia is one of the most common respiratory problems encountered by sheep and goat producers. While pneumonia may be much less common a problem than other health concerns such as internal parasites, it can still cause significant losses in production and occasional death loss within any given herd. Occasionally, producers may experience an outbreak of disease that leads to numerous animals affected and severe losses. My experience suggests that summertime represents an increased number of cases in southwest Missouri.

It should come as no surprise that the farm population is aging. I have seen this phenomenon develop over the past 15 years I have been in the veterinary practice, and it shows little sign of change. There has also been a decrease in the number of large animal veterinarians in rural areas of not only Missouri, but throughout the nation. One way you and I can help slow these trends is to mentor young people that have an interest in agriculture and livestock production.

The harsh conditions of winter can present a challenge to some horses in maintaining an adequate body condition. Colder temperatures require increased calorie intake to maintain body warmth. Loss of body condition is often a very gradual process, occurring over several weeks to months, the problem can "sneak up" on horse owners if they are not proactively observing and maintaining their horse’s body condition.
