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.

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

Abomasal bloat, or abomasitis, is a condition seen in calves less than three weeks old. We have recently seen several cases at our clinic, and unfortunately, most cases are fatal without very rapid intervention. The good news is that good management and preventive measures can all but eliminate this disease.

Getting young stock off to a good start is critical to the success of any livestock operation. For most livestock species, the successful transfer of maternal immunity from a dam to her offspring is the first step and also the cornerstone of neonatal health. Whether we are discussing foals, calves or goat kids, all rely heavily on the ‘passive transfer’ of immunity by means of the first milk or colostrum to provide protection from disease.

Blackleg is a disease that most cattle producers are relatively familiar with, if for no other reason than the ‘blackleg’ vaccine is probably the most commonly administered vaccination by cattle producers. And this for good reason, because for those producers that may have elected to forgo vaccination and unfortunately experienced the disease firsthand as a result, blackleg can be truly unforgettable. The disease frequently affects the biggest, fastest growing calves and renders them acutely dead in the majority of cases.

Fall is now officially here, fall calving is in full swing and now is the time to start thinking about your bull power for breeding season coming in less than two months. Too many times in my practice over the past 20 years I have seen cattlemen plan and strategize for handling cows and heifers for the upcoming breeding season, only to forget that their bulls are an equally important part of the breeding equation. I would suggest, rather than a last minute rush, that you start planning now to make sure the bulls are ready to perform.

Once again this year we are seeing a rise in the number of cases of rabies in our state. This year according to the Missouri Department of Health, the state has had 23 cases compared to 17 cases at this same time last year. Currently, four counties are on alert those counties are Bollinger, Howell, Oregon and Wayne. Alerts are issued when the disease has been reported in domestic animals. The majority of cases this year has been in skunks, with 15 positive. The remainder of these cases have been in domestic animals including horses, dogs and cats.
