Respiratory Disease in Adult Cattle
نویسندگان
چکیده
Respiratory disease in cattle is often associated with the youngest animals such as calves, heifers or steers (Hartel et al. 2004; Ames, 1997). Most cases appear before the age of two-years old (if not before the end of the first month of life-Crowe, 2001), and respiratory disease is a major cause of losses, particularly in beef cattle production (Prado et al. 2005; Kapil & Basaraba, 1997; Johnson, 1991).
