Optimizing welfare in transport and slaughter of cattle

Abstract

Transport represents one of the most stressful events an animal may experience. Its impact on the welfare of beef and dairy cattle is frequently underestimated, as are the effects of transport on carcass quality issues such as bruises and dark cutting beef. For ease of discussion, the process is broken down into three phases: pre-transport, transport and arrival at slaughter. The pre-transport phase includes selection of animals to be removed from herds and determining their fitness for travel, and making preparations based upon weather conditions, time and distance to the ultimate destination. The behavioral tendency of cattle to stand during transport increases stress, fatigue and the potential for injury as time in transit increases, especially for compromised animals. Upon arrival at slaughter, animals should exit at that their own speed into an alleyway that provides an obvious unrestricted path to follow in route to a holding pen. The holding pen should provide immediate access to water and be large enough to avoid overcrowding of animals. The movement of animals from the pre-slaughter holding pen to the alleyway leading to the stun box should move in an orderly and calm manner with little, or preferably no use of prodding devices. Once the animal enters the restrainer, stunning should proceed without delay.
