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.

Internal parasitism is one of the most challenging of health concerns in small ruminants.

With the weather cooling as I write this article, I have seen a noticeable increase in scheduling for calf processing.  So I thought this might be a good time to discuss pre-conditioning programs and what I believe is their value to the cow-calf producer.

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.

'Colic’ is a general term used to describe abdominal pain and is a clinical syndrome that is commonly recognized in horses. Colic can be caused by many different abnormalities occurring within the abdominal cavity of the horse. For horse owners it is advantageous to be familiar with the clinical signs, diagnosis and treatment options for colic as most horses will encounter this problem at some point in their lives.

It seems that every other week I hear about how unsafe our food supply has become, that livestock producers are poisoning an unknowing public with all manner of substances and that antibiotic use in livestock should be banned because of bacterial resistance to certain antibiotics. Much of what I hear on news shows and read in magazines or newspapers seems often to be biased against prudent use of pharmaceuticals in livestock production. I have a few thoughts based on experience and research that I would like to discuss in more detail in this column.
There are innumerable articles detailing all sides of the problem of antibiotic resistance, food safety and livestock production in general.

An outbreak of equine herpes virus has created quite a stir in the horse world recently. Several horses that attended the National Cutting Horse Association's Western National Championships in Ogden, Utah this May later developed neurologic signs and then tested positive for Equine Herpesvirus-1. Several shows have subsequently been cancelled, some farms have been quarantined and a few of the affected horses unfortunately euthanized as a result of the outbreak.

While driving cross country in between calls I have noticed from the road a few cattle beginning to show evidence of lice infestation. Cattle, horses, sheep, goats and swine are all susceptible to parasitism from lice. Interestingly enough, lice are species specific meaning that there is a particular species of louse that prefers feeding on a specific species of livestock. Furthermore, in each species of livestock there are two types of lice that may be observed. Biting lice feed on dead skin cells and other debris from the surface of the skin. Sucking lice feed off of the blood. All species and types of lice cause skin irritation and in rare instances sucking lice may cause significant anemia.

One of the most common diseases among cattle during the summer months is pinkeye or ‘bovine infectious keratitis’. Many producers battle this disease every year even when preventative measures are taken. Thankfully, mortality with this disease is generally low or absent, however, morbidity may be as high as 80 percent. Economic losses are generally realized in treatment costs, reduced gains/milk production and reduced sale prices for animals with blindness or chronic lesions of the eye.

For those of you who don’t know it yet, winter is officially here, and by all accounts it has already been a cold one. I would like to cover a few points to think about while you read this next to the fireplace or wood stove; these small things can help your livestock in the upcoming months.
