When researching diseases that affect animals, I chose to research one that deals with cattle. This disease would be a reproductive venereal disease called vibriosis. Vibriosis can affect all breeds of cattle, male or female, and is the most important cause of infertility in female cattle along with occasional abortions. This disease is caused by bacteria that live in the crevices of a bull’s prepuce, of a bull aged four years or older (Hansen, 1914). Age is a factor because the foreskin of a bull does not develop until then. The disease is spread from an infected bull to a cow during breeding. A bull might be clean, but then infected by a cow who was infected by a bull before him. Many bulls can go years without showing any signs of this disease, whereas female cattle may lose a calf to an abortion the next coming calving season.
Again, the major upsets this disease causes is infertility and abortions (Hansen, 1914). Vibriosis in females causes endometritis. This means ...view middle of the document...
Infection introduced into a non-exposed or non-vaccinated herd will spread rapidly during breeding.
To prevent the spread of this disease vaccinating of cattle whether they have this disease or not should be done. This will greatly prevent them from contracting the disease. The use of artificial insemination should also be done (Clinic, 2005). This will conclude that an unknown infected bull could not breed in the pasture. AI organizations test the semen to assure it is free of vibriosis and trichomoniasis (Hansen, 1914). Also treating infected animals as they are found begins to stop the spread right then. Vaccinations should be given four weeks before the bulls and heifers should be allowed to join the herd (Hum, 2007). This is not mandatory, but does insure that the vaccine is in. Vaccination of an infected head of cattle starts with two injections four to six weeks apart in the first year, and then one dose of the vaccination each year afterwards (Hum, 2007). Many cattle affected recover within a year. When doing all three of these steps, the highest level of prevention is used. If we check cattle for this bacterial disease before breeding we can catch it before it infects. This management greatly controls the spread of the disease. The public health concerns that come along with this cattle disease is that is can infect humans. If an aborted fetus from an infected mother is not handled with care, a human can contract the disease. This can lead to a severe intestinal disease in the human.
This disease is important to me because it taught me of something I need to check in my cattle before the breeding season begins. It is much easier to vaccinate then to risk the chance of one head being infected and then infecting many other of a herd. I want my cattle to be at the best performance all the time and making profit. Even though this disease is treatable, it can really slow down the production of calving and money due to a cow or bull being down. This disease is checked for in semen in AI, which gives me more of a comfort knowing that AI is yet again a successful production tool when I choose to use it. When I don’t use AI, I will know to check for vibriosis. I learned of a simple disease that I can now look out for in the future.
