“…When fattened finished feedlot cattle with heavy back fat are forced to run, both plasma lactate and serum cortisol were significantly higher (Frese et al 2016). In cattle, vocalisation (moo or bellow) during handling and restraint is associated with higher cortisol concentration (Dunn 1990;Hemsworth et al 2011). Blood samples were collected after slaughter.…”

“…Vocalisation of cattle during handling in a squeeze chute or other restraint device is a good measure of animal-welfare problems during handling, because it is associated with obvious aversive events such as electric-prod use or excessive pressure applied by a restraint device (Grandin 1998b;Bourguet et al 2011;Hemsworth et al 2011). Reducing the pressure applied by a head restraint reduced the percentage of cattle vocalising from 23% to 0% (Grandin 2001).…”

“…Yelling and screaming at animals is stressful (Pajor et al 2003). Hemsworth et al (2011) found that yelling raises cortisol but normal talking has no effect. When cattle are handled quietly, they will have lower plasma cortisol than do cattle that are handled roughly (Petherick et al 2009).…”

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.

“…Electric goads are highly aversive [45,48], and many countries have strict regulations about their application to animals. Often, simple changes in the design of facilities, or improved education of handlers can significantly reduce the need for the use of electric goads, or other moving aids [40,[48][49][50], improving animal welfare.…”

Why Pain Is Still a Welfare Issue for Farm Animals, and How Facial Expression Could Be the Answer

Pain is a sensory and emotional experience that significantly affects animal welfare and has negative impacts on the economics of farming. Pain is often associated with common production diseases such as lameness and mastitis, as well as introduced to the animal through routine husbandry practices such as castration and tail docking. Farm animals are prey species which tend not to overtly express pain or weakness, making recognizing and evaluating pain incredibly difficult. Current methods of pain assessment do not provide information on what the animal is experiencing at that moment in time, only that its experience is having a long term negative impact on its behavior and biological functioning. Measures that provide reliable information about the animals' affective state in that moment are urgently required; facial expression as a pain assessment tool has this ability. Automation of the detection and analysis of facial expression is currently in development, providing further incentive to use these methods in animal welfare assessment.
