Prevalence of severe welfare problems in horses that arrive at slaughter plants

Abstract

Objective: To assess the prevalence of severe welfare problems in horses that arrive at slaughter plants and to identify horses that were unfit for travel.

Design: Prevalence survey.

Animals: 1,008 horses.

Procedure: Horses arriving at 2 slaughter plants were observed. The following were rated severe welfare problems in horses: body condition scores of 1 or 2 (emaciated) of 9; recumbency (down) or the inability to walk; fractured limbs or other foot or limb problems that extremely impaired mobility; severe wounds, such as deep cuts, extensive lacerations, abrasions on the head or back, eye injuries, neglected purulent lesions, and numerous bite and kick marks over extensive areas of the body; and dead on arrival. Bruises on carcasses were tabulated to further assess injuries. Horses that had been loaded with a fractured limb, arrived nonambulatory, had severe lameness that interfered with mobility, were weak and emaciated, or were dead on arrival or died shortly after arrival were considered unfit for travel.

Results: Ninety-two percent (930/1,008) of the horses arrived in good condition, and 7.7% (78) had a condition that was rated a serious welfare problem. Thirty horses (3%) had a body condition score of 1 or 2, 12 (1.0%) had foot and limb problems (other than fractures), 4 (0.4%) had fractured limbs, 18 (2.0%) had deep cuts, lacerations, or injuries from bites, 8 (0.8%) were nonambulatory or dead on arrival, 2 (0.2%) had deformities, 3 (0.3%) had extensive purulent lesions, and 1 (0.1%) had a behavior problem. Characteristic patterns of 51% of carcass bruises indicated that they were caused by bites or kicks. Fighting was the major cause of injuries that occurred during transport and marketing. Fifteen (1.5%) horses were unfit for travel. Abuse or neglect by owners was the cause of 77% of the severe welfare problems observed.

Clinical implications: To decrease the number of injuries that result from fighting when transporting horses to slaughter plants, aggressive mares and geldings that continually attack other horses must be segregated.
