The diagnosis of the disease is complex since there are multiple possible causes and cattle are reluctant to display any indications of pain. [ 4 ] The disease manifests itself most often in calves within four weeks of weaning , when calves are sorted into groups of roughly 10-15 in number, and sold to different feedlots via train, tractor ...
Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs. It is marked by cough, dyspnea, anorexia and constipation.
Eye Ring. Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease [1] caused by a group of ruminant gamma herpes viruses including Alcelaphine gammaherpesvirus 1 (AlHV-1) [2] and Ovine gammaherpesvirus 2 (OvHV-2) [1] [3] These viruses cause unapparent infection in their reservoir hosts (sheep with OvHV-2 and wildebeest with AlHV-1), but are usually fatal in cattle and ...
Diagnosis is typically based on history and clinical findings when the veterinarian examines the cow. [2] Symptoms of hardware disease vary depending on where the object penetrates. [3] The cow exhibits an arched back, a reluctance to move and a slow, careful gait. The cow may groan when lying down, getting up, defecating and urinating.
This disease affects the upper respiratory tract as well as the reproductive tract of cattle, and is commonly found in feedlots across North America. [2] Clinical symptoms include fever, serous to mucopurulent nasal discharge, coughing, sneezing, difficulty breathing, conjunctivitis and loss of appetite. Ulcers commonly occur in the mouth and nose.
Control of the disease relies on control of ticks of domestic animals. This is a major concern in tropical countries with large livestock populations, especially in the endemic area. Pesticides (acaricides) are applied in dipping baths or spray races, and cattle breeds with good ability to acquire immune resistance to the vector ticks are used.
Contagious bovine pleuropneumonia (CBPP – also known as lung plague), is a contagious bacterial disease that afflicts the lungs of cattle, buffalo, zebu, and yaks. It is caused by the bacterium Mycoplasma mycoides, and the symptoms are pneumonia and inflammation of the lung membranes. [1] The incubation period is 20 to 123 days.
An estimated 400,000 cattle infected with BSE entered the human food chain in the 1980s. [citation needed] Although the BSE epizootic was eventually brought under control by culling all suspect cattle populations, people are still being diagnosed with vCJD each year (though the number of new cases currently has dropped to fewer than five per ...
