There have been many recent reports of deer found dead throughout Missouri; many of these deer have been reported to have died from bluetongue, but in all likelihood, most of these animals were infected with a disease known as epizootic hemorrhagic disease, or EHD. This viral disease is potentially devastating to the white tail deer population both wild and captive, and can affect domestic ruminants.

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.

Arguably the most significant health concern regarding dairy production is that of mastitis. By definition, mastitis is inflammation of the mammary gland of the cow. This inflammation is typically a result of invasion and infection of the mammary gland by bacterial organisms. When considering the strategic treatment and prevention of mastitis, bacterial organisms are commonly divided into two groups: contagious and environmental pathogens.

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.

In a previous issue we discussed an emerging disease in Missouri cattle known as trichomoniasis or ‘trich’. This issue provides an excellent opportunity to bring producers up to date on recent changes in Missouri state regulations.

Creating a biosecurity plan is one of the most powerful means of preventing disease-related problems in beef cow-calf herds. The primary goal of a biosecurity plan is to prevent the introduction of disease into the herd.  This can be coupled with efforts to prevent transmission of disease within the herd and plans to eliminate disease carrying individuals. This is particularly applicable to purebred producers in that a disease-free status can add significant value to marketable seedstock. Similarly, however, smaller commercial producers can also benefit greatly from some basic biosecurity practices.

If you’ve been in the cattle business long you have probably heard of the downer cow syndrome, or chances are, have had a downer cow of your own. This is a very common presentation and vets frequently get called out to examine cows that, for any number of reasons, are down and cannot get up. There is some irony in this condition as the apparent superficial problem is quiet easy to identify – the cow’s inability to rise. However, identifying the underlying cause for her apparent problem can be challenging and complex, hence the term, downer cow ‘syndrome’.

Many types of squeeze chutes exist today, each with features that make cattle restraint easier.

The abomasum is the fourth compartment of the stomach in the cow. This compartment is most like the simple stomach of humans or the horse in that it is the only glandular portion of the stomach of cows secreting hydrochloric acid and enzymes. The abomasum must function normally for cows to maintain their health and production. Dysfunction of the abomasum, namely displacement, is one of the most common causes of a need for abdominal surgery in the bovine.

Spring is the traditional time of year for breeding on most horse ranches. Horses are long-day breeders meaning that natural reproductive activity peaks during the longer days of the year. Generally, from mid-spring through the summer mares regularly cycle every 21 days.
