Eventually the snow will melt and spring will bring rain. Warmer weather and excessive ground water brings the perfect conditions for mosquito proliferation. There are approximately 50 species of mosquitoes native to Missouri according to the Department of Conservation. Even-though warm weather is usually associated with those pesky insects there are species active during every season of the year. The only reprieve is during freezing temperatures but warmer environments such as in the house or barn may allow mosquitoes to overwinter.

May is just around the corner. Are you ready for spring bull turnout? Many of you are in the middle of calving and some may have just started. Don’t let the hustle and bustle of this calving season derail your next calf crop. The star(s) of your operation are the bulls, which are often ignored and forgotten most of the year. However, it is critical to have a plan prior to turnout as too how much bull power you will need versus how much you have. Simple questions to start the decision making process are: How many cows will need bred? How many groups are those cows divided into? How many heifers, and do you have a bull designated for your heifers? Are you going to synchronize the herd or heifers? Do you have a backup plan if your bull fails the Breeding Soundness Evaluation? What condition are your bulls in?

As spring approaches, many goat producers are preparing for the beginning of kidding season. One condition that producers may encounter as does enter their last trimester of pregnancy and near parturition (birthing) is ‘pregnancy toxemia’. This can be a life-threatening condition for some does and early recognition of this disease is paramount to providing successful treatment. This very same condition is also seen in sheep with similar clinical signs and treatment options.

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. I ask the question “Is their requirement of protein for animals in their diet?” Actually “NO.” Animals must have the 10 essential amino acids and cats require 11 amino acids.

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.

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.

We are currently seeing an increase in rabies cases in our state. For several years we have been told by health officials that we should expect an increase in rabies cases as the virus moves north from Mexico. Since there is a significant health risk to humans, we need to be aware of what is happening. Rabies in humans is close to 100 percent fatal.

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.
