Pictures - Recognizing Health-Related Problems


Below is compilation of pictures and web site where you can see and learn more about health related issues in dairy cattle.


Bottle Jaw

"Bottle jaw", also called submandibular edema, is a sign very typical of Johne's disease. Bottle jaw is due to protein (albumin) loss from the bloodstream into the intestinal tract leading to low blood protein. Animals at this stage of the disease will not live very long, perhaps a few weeks at the most. Parasitism and some other disease conditions in cattle can also cause bottle jaw. The picture below was borrowed from Dr. Michael Collins and Dr. Margaret Manning and was posted at The University of Wisconsin School of Veterinary Medicine photo gallery.

Hairy Foot Wart (Papillomatous digital dermatitis)

Contrary to what the name implies hairy foot warts are not warts at all. Viruses cause warts; bacteria cause hairy foot warts. The exact causative agent is not known, but evidence suggests that one or more species of spirochete of the genus Treponema is responsible. Treponema bacteria can be anaerobic or microaerophilic (require O2 at less than atmospheric levels) and can be parasitic to humans and to animals causing a range of diseases.

Currently, the most effective treatment is the use of topical broad-spectrum antibiotics; however, treatment of hairy foot warts with antibiotics is off-label so consult your veterinarian before use. One alternative to topical antibiotics is medicated footbaths. Advantages to the use of footbaths (copper sulfat, zinc sulftate, formalin, peroxides or iodine products) are that mass treatment can be achieved with little direct labor input.

Foot Rot

Foot rot is a subacute or acute necrotic (decaying) infectious disease of cattle causing swelling and lameness in one or more feet. The disease can become chronic with a poorer prognosis for recovery if treatment is delayed. Fusobacterium necrophorum is the bacterium most often isolated from infected feet

Treatment of foot rot is usually successful, especially when instituted early in the disease course. Treatment should always begin with cleaning and examining the foot to establish that lameness is actually due to foot rot. At this time a topical treatment of your choice should be applied. Some very mild cases will respond to topical therapy only. Most cases require the use of systemic antimicrobial therapy. A complete on-line article on foot rot (that includes the picture below) has been written by J. G. Kirkpatrick, DVM and Dr. D. Lalman, Extension Beef Specialist, Oklahoma State University.

Johne's

The picture below, a Guernsey at a terminal stage of the disease, was borrowed from The University of Wisconsin School of Veterinary Medicine photo gallery. Please visit their web site. There are pictures and lots more about this disease.

Ringworm

The "Photbar" Agricultural Stock web gallery has great pictures of Jerseys and Holsteins with ringworm. Please visit their copyrighted web site.

See more pictures and read about ringworm (dermatophytosis) from the School of Veterinary Medicine, zoonotic disease tutorial web site.

Diseases that can be transmitted from animals to humans are called zoonotic diseases. Ringworm is one of those disease. See the Center for Disease control (CDC) web site for information on ringworm in humans and the National Institute of Health for pictures of ringworm in humans.
