摘要

Bovine Respiratory Disease (BRD) is a significant cause of morbidity and mortality amongst cattle in Australian feedlots. Numerous studies have been conducted in North America to investigate non-infectious risk factors for the disease, but to date, there is no published data based upon Australian findings. North American research has indicated that environmental factors are of great importance in the epidemiology of Bovine Respiratory Disease. A retrospective case-control study was conducted upon a cattle population in a northern New South Wales commercial feedlot over an eleven month period in 1994. Background data from 33,321 domestic trade cattle was used in this study. The factors under investigation were distance travelled from property of origin to the feedlot, bodyweight at induction, acaricidal dipping in transmit, sex, breed, state of origin and zone and within state of origin (public auction vs. private sale), backgrounding and season of induction.
