How do we keep from leaving money on the table?

Watch for acorn toxicosis this fall.

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?

Show season is upon us again. Remember show animals are exposed to more diseases as they are co-mingled with others. Vaccinations of these show animals are a must. Consult your veterinarian as to which vaccines are recommended.

While dealing with the ice and cold weather I have noticed our nutrition gurus are looking more and more 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.

Someone I know recently became very sick with diarrhea, and was diagnosed with cryptosporidiosis. Cryptosporidiosis is caused by a protozoal parasite similar to coccidia.  This parasite causes diarrhea in calves that leads to untold millions in lost production in both the dairy and beef industries. Since this disease has zoonotic potential, that is, it can be transmitted from animals to people, I think a discussion of the disease and control measures is needed.

The wet weather we have been dealing with for most of this year has brought with it several challenges for livestock producers throughout southwest Missouri. Wet and cold weather led to increased calf losses early this year, and wet fields have not allowed farmers to harvest hay crops that appear plentiful to the average person driving down the road. But I have observed another problem this year affecting horses and cattle. While I don’t have scientific proof or hard statistics to prove my theory, it is my opinion that I have had a number of cases where the problem seemed to stem from access to tall fescue, and I am concerned that fescue toxicosis could be a significant problem this year.

In the last issue we discussed pinkeye as a major cause of disease in cattle during the summer months. Another problem that frequently presents itself in my chute during the summer is foot rot. I have seen numerous cases of foot rot in cattle this summer already. The disease is caused primarily by a bacterium called Fusobacterium necrophorum and is a significant cause of lameness in cattle – beef and dairy alike. Like pinkeye, mortality from the disease is generally absent but morbidity can get high with up to 25 percent of the herd affected in severe outbreaks. Foot rot can be a significant source of lost production. Cows that are lame from foot rot tend to lie around, eat less and produce less milk. Whether that milk is going into the bulk tank or into the calf, less milk means less money to the producer. Additionally, treatment costs and the occasional animal with unresolving lameness represent further economic loss due to the disease.

Recently in southwest Missouri we have seen an increase in number of herds affected with Trichomoniasis. This disease is a reproductive nightmare. It can be devastating to the owner. Reducing the calf crop and eliminating any significant income for that herd.

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.
