“…Numerical scoring systems have been developed for detecting problems during handling (Grandin 1998a;Maria et al 2004;NCBA-BQA Feedlot Audit 2009;Welfare Quality Network 2009;Edwards et al 2010;Hulgren et al 2014). This makes it possible to determine whether handling has improved or become worse.…”

“…For short-term stressors such as handling, physiological measures of stress may be really useful if the blood is sampled shortly after handling. Physiological measures can easily show differences between low-stress and high-stress handling (Edwards et al 2010;Brandt and Aaslying 2015). At the slaughter plant, when pigs and cattle were moved with electric prods or jammed in the race that leads to the stunner, lactate and glucose concentrations are higher (Edwards et al 2010;Gruber et al 2010).…”

Edwards et al (2010) measured blood lactate in pigs and Gruber et al (2010) measured plasma lactate and plasma glucose in cattle. Benjamin et al (2001) found that both glucose and blood lactate were doubled or tripled immediately after aggressive handling with multiple shocks from an electric prod, compared with calm handling with no prods.…”

Abstract. Assessing animal welfare during handling for veterinary procedures or loading onto a truck is simpler than is assessing welfare in housing. The first step is preventing acts of abuse that everybody who is interested in animal welfare would want stopped. Acts of abuse include beating animals, poking sensitive areas, dragging downed animals, deliberate slamming of gates on animals or deliberate driving animals over the top of downed animals. The next step is to implement objective numerical scoring of animal handling. The outcome measures that should be used are percentage of animals that fall, strike fences or gates, vocalise during restraint, are miscaught in the head stanchion or are moved with electric goads. Repeating these measurements over a period of time will make it possible to determine whether practices are improving or deteriorating. Further improvements in handling can be obtained with stockmanship training. Physiological measures of stress such as cortisol, lactate or glucose are useful for assessing handling methods because handling is a short-term stressor.
