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.

It is the time of year when cattle are seen rubbing on trees, fence post, feeders or anything they can. They will rub until the skin becomes raw, thick and irritated and often the cause for this is lice. It costs cattle producers millions of dollars in losses each year. They are biting the lice, which live on their skin and hair. These are a sucking lice. Sucking lice tend to cause anemia, which will cause the immune system to become weaker leading to other illnesses. The lice will cause a decrease in weight gain and in milk production, and this will lead to an increase in feed costs and cause you to treat other issues resulting in less profit.

While dealing with the ice and cold weather I have noticed our nutrition gurus are looking more and moiré into balancing rations of essential amino acids instead of protein.

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.

In the last issue we introduced the topic of bacterial pneumonia in cattle and discussed the significance of the disease, the basic mechanisms involved that result in pneumonia and effective prevention strategies. In this issue our focus will be on prompt and accurate diagnosis, followed by currently recommended treatment protocols.

Urolithiasis is a common condition in goats and typically affects young wethers. It is characterized by small, crystallized stones (urinary calculi) forming in the urine which then settle out in the bladder and cause disease when they obstruct the outflow of the urethra and render the animal unable to urinate. This condition is of major significance due simply to the fact that it can make animals very sick very quickly and often results in death if not effectively treated soon enough.
