Prevalence of lesions and body condition scores among female swine at slaughter.

摘要

Carcasses of culled gilts and sows killed during a 1-week period in July 1994 at an abattoir in Midwest USA were examined. Lesions were recorded and body condition was scored on the basis of standard criteria. 58.9% (1029/1747) of the carcasses hadfoot lesions, 67.3% (1178/1751) had dermatitis and 4.6% (80/1751) had shoulder lesions. Body condition score was significantly associated with detection of dermatitis and shoulder lesions. Mean number of teats (1432 carcasses) was 13.86±0.02. Mean numbers of normal-appearing teats in the left and right mammary chains were 6.57±0.02 and 6.58±0.02, respectively. Feet from 48% (688/1433) of the carcasses were condemned. Visceral lesions were found in 48.8% (624/1278) of the carcasses; of the carcasses withlesions, 412 (66%) had liver spots, and 268 (42.9%) had pneumonia. It is suggested that monitoring culled sows and gilts at slaughter may help identify lesions that could adversely affect breeding herd productivity.
