Beef Cattle Diseases Anthrax Spores stay in the ground No treatment Vaccinate against BRSV Bovine Respiratory Syncytial Virus Basically like pneumonia Respiratory disease BSE bovine spongiform encephalopathy progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion. Two cases in 1986 originated as a result of feeding cattle meat-andbone meal that contained BSE-infected products from a spontaneously occurring case of BSE or scrapie-infected sheep products BSE BVD Bovine Virus Diarrhea damage to the digestive and immune systems, pneumonia, abortions, calf deformities, and others. Clinical signs in newborn calves infected with BVD include fever, nasal discharge, diarrhea, and inability to move about normally. Live virus BVD vaccine – could have negative effects though Brucellosis Symptoms Acute brucellosis may begin with mild flu-like symptoms, or symptoms such as: Abdominal pain Back pain Chills Excessive sweating Fatigue Fever Headache Joint pain Loss of appetite Weakness Weight loss High fever spikes usually occur every afternoon. The name "undulant" fever is because the fever rises and falls in waves. Other symptoms that may occur with this disease: Muscle pain Swollen glands The illness may be chronic and last for years. Blackleg The bacteria enters the calf by ingestion and then gains entrance to the body through small punctures in the mucous membrane of the digestive tract. Cattle that are on a high plane of nutrition, rapidly gaining weight and between 6 months and 2 years of age are most susceptible to the disease. The disease is not transmitted directly from sick animals to healthy animals by mere contact. The first sign observed is usually lameness, loss of appetite, rapid breathing and the animal is usually depressed and has a high fever. Characteristic swellings develop in the hip, shoulder, chest, back, neck or elsewhere. First the swelling is small, hot and painful. Blackleg Muscle Foot and Mouth caused by one of the smallest disease producing viruses known. Humans do not catch the virus. The disease is characterized by blister-like lesions on the tongue, nose and lips, in the mouth, on the teats and between the toes which then burst, leaving painful ulcers. The blisters cause a heavy flow of sticky, foamy saliva that hangs from the mouth. Infected animals sway from one foot to the other due to the tenderness of the feet IBR Infectious bovine rhinotracheitis - Red nose This infection usually occurs in the air passages of the head and the wind pipe. However, in females this virus also causes inflammation of the vulva and vagina and abortion. Abortion occurs about 20 to 45 days after infection. Usually goes with shipping fever Johne’s disease a contagious, chronic and sometimes fatal infection that primarily affects the small intestine of ruminants. Leptospirosis chronic (long lasting) or acute (short lasting) show signs restlessness, loss of appetite, fever and nervous system disorders. Although not seen in every case, the most notable symptom gives this disease its nickname, "Circling Disease." Cattle with listeriosis are often seen walking in circles. Other, more subtle symptoms include uncoordinated movements, leaning against objects, and progressive paralysis. Death can occur within 2 to 3 days after the onset of symptoms, but cattle can survive for up to 2 weeks with the disease. Lumpy jaw produces immovable hard swellings on the upper and lower jawbones of cattle, commonly at the central molar level. It is caused by an anaerobic micro-organism Pinkeye redness and inflammation of the lining of the eyelid and eyeball. non-fatal Pinkeye and foot rot are the two most prevalent conditions affecting all breeding beef females Trichomoniasis venereal disease of cattle that causes infertility and occasional abortions in cows and heifers. Warts Wart Vaccine Cut off and feed to them Wooden Tongue Bacteria lives in the mouth, invade tissue through breaks in the lining of the mouth. Any rough feed can cause mouth abrasions which allow entry of infection. The disease starts suddenly with the tongue becoming hard, swollen and painful Wodden Tongue Ringworm Not a worm Similar to athletes foot
