New rules regarding identification of livestock from one state to another became effective on March 11, 2013.  These rules were designed to assist with traceability of livestock in the event of a disease outbreak in the United States. The new rules were originally posted on January 9, 2013, but were postponed until March while revisions were made after several comments from the public. The new rules apply primarily to cattle and include several changes in recording identification for health certificates accompanying cattle transported across state lines. The new rules describe the classes of animals required to have official identification, the types of official identification allowed and the record keeping and documentation requirements for the new identification rules.

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.

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.

Flies are a well known and common pest to most all classes of livestock. With heat and humidity, flies thrive and this makes summer in the Ozarks a prime environment for fly populations. Economic losses can be substantial, particularly in beef and dairy cattle. In cattle, flies can cause production losses in the way of reduced weight gain, lowered milk production and the transmission of disease.

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.

It is summertime, and with rising temperatures combined with high humidity, heat stress will play an important factor in all cattle operations for the next couple of months.

Well, it has finally warmed up.  And with three to four days of warm weather I have already started seeing flies on many of the cattle I work on daily.  So what are your options to control flies and other parasites to minimize the damage done to your cattle’s production? Let’s take a look at several options for both external and internal parasites.

This past week I was asked to necropsy a 1-week-old calf found dead. The owner had seen no evidence of sickness and the calf was with its mother all the time. The necropsy revealed an extremely emaciated body with no internal body fat present. The second client was a dairy client who was having trouble with calves dying between 1-2 weeks of age, with minimal clinical diarrhea or respiratory symptoms. While these cases are quite different, they got me to thinking about the reasons I see similar cases every year during this winter season.

The news has been full of information regarding influenza virus in recent months whether discussing the shortage of flu vaccines available for people, the spread of H1N1 or the more recent discussion of canine influenza. In this article, we are diverting a bit from livestock medicine to more of a companion animal topic, but I suspect that this topic may be of interest to most of our readers. In response to the recent media coverage I have begun to get questions regarding canine influenza, the signs of infection and need for vaccination.

Last year producers experienced falling calf prices and input costs that went through the roof. This year calf prices are still expected to be low but for cow-calf operators these difficult times can be seen as an opportunity.
