It is breeding season once again and we often get the question, “will heat synchronization work in heifers?” Heat synchronization will work, but before we say yes, I like to look at each individual case and see if the producer has the time and facilities to do so. Some producers want to do large numbers, other may only have a few cows, and so each case must be assessed differently.

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.

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.

According to the calendar, spring is here and you have your calf crop on the ground and are thinking maybe you should be going over the farm equipment before spring planting starts. Something else you should be thinking about is getting ready for breeding season so that you have a new calf crop for next year. Some planning now on your part can go along way to making next year’s calf crop successful.

My practice has several small ruminant herds in it. We see a few cases each year of Caprine Arthritis Encephalitis (CAE) or Infectious Leukoencephalomyelitis. This disease is devastating to the animal it affects. CAE is usually seen in young goats. The most important thing to remember is there are no effective treatments for CAE. Prevention is the only way to control this syndrome.

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.

There are several tools available for cow/calf producers that can lead to a decrease in one of the primary problems seen in neonatal calves – diarrhea. Diarrhea is a leading cause of mortality in baby calves and has many causes.

As we enter the New Year many of my horse clients are making plans for the spring. This is the time of year to start thinking about vaccinating, don’t wait. Remember vaccines do not provide immediate protection, some require four to six weeks for protective immunity. If you are planning on moving your horse out of state for any reason do not wait until the last minute for your EIA (Coggin’s) test.

Each year producers have lost several dollars in profit, either by loosing calves or in the expense of treating calves that have diarrhea problems. These problems can be in most cases prevented with good management practices. Calf diarrhea may be caused by bacteria, viral or poor nutrition.

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.
