ID-135: Infectious Bovine Keratoconjunctivitis ("Pinkeye") in Cattle

Michelle Arnold, John Johns, Jeff Lehmkuhler, Patty Scharko | Sep. 24, 2012 (Major Revision)

Infectious Bovine Keratoconjunctivitis (IBK), also known as pinkeye, is a costly disease for the beef producer. Tremendous losses stem from poor weight gain and loss of appetite in affected animals suffering from visual impairment and ocular pain.

ID-190: Staphylococcus Aureus Mastitis

Michelle Arnold, Jeffrey Bewley | Mar. 5, 2012 (Reprinted)

Staphylococcus aureus is an important bacterial cause of contagious mastitis on dairy farms worldwide. More importantly, it is often at the root of chronically high somatic cell counts, recurrent clinical mastitis, and damaged mammary gland tissue. It is considered to be a contagious udder pathogen that spreads within and between cows during milking. Because it is often subclinical (milk looks normal but with a potentially high somatic cell count), infected animals pose a risk of infection to herd mates during each milking.

ID-186: Managing Legume Induced Bloat in Cattle

Michelle Arnold, Roy Burris, David Ditsch, Garry Lacefield, Jeff Lehmkuhler | Mar. 10, 2011 (New)

Ruminal tympany, or bloat, can result in lost animal performance and in severe cases, death. It occurs as a result of a buildup of fermentation gases in the rumen. Bloat may be categorized as frothy bloat, which is caused by the formation of a stable foam in the rumen, or free gas bloat, which is due to excessive production of gaseous compounds from fermentation or as a result of an obstruction preventing the escape of gas compounds. Legume bloat is a frothy bloat condition.
