“…For instance, work on dairy calves found a negative judgment bias in the hours following hot-iron disbudding (Neave et al, 2013;Daros et al, 2014) and separation from the dam (Daros et al, 2014). Work on other farm animals has explored the effects of different types of housing (pigs; Douglas et al, 2012), prenatal stress (lambs; Coulon et al, 2015) and chronic stress (sheep; Destrez et al, 2012). No study to date has examined judgment biases in adult dairy cattle.…”

Affective states, which refer to feelings or emotions, are a key component of animal welfare, but these are also difficult to assess. Drawing upon a body of theoretical and applied work, we critically review the scientific literature on the assessment of affective states in animals, drawing examples where possible from research on dairy cattle, and highlighting the strengths and weaknesses of scientific methods used to assess affective states in animals. We adopt the "valence/arousal" framework, describing affect as a 2-dimensional space (with valence referring to whether an experience is positive or negative, and arousal referring to the intensity of the experience). We conclude that spontaneous physiological and behavioral responses typically reflect arousal, whereas learned responses can be valuable when investigating valence. We also conclude that the assessment of affective states can be furthered using mood assessments and that the use of drug treatments with known emotional effects in humans can be helpful in the assessment of specific affective states in animals.

“…However, if the animal does not respond or the latency to respond is similar to that of the negative cue/location then the response is considered as being pessimistic. This type of test has been used to assess judgement bias in livestock including sheep (Doyle et al, 2010;Sanger et al, 2011;Destrez et al, 2012), pigs (Douglas et al, 2012), cattle (Neave et al, 2013) and poultry (Salmeto et al, 2011;Wichman et al, 2012) and most such tests are sensitive enough to detect differences attributed to the affective state of the animals. However, it has been argued that this type of task, where the only outcome measured is the latency to approach or not approach within a time limit, has limitations in its interpretation as negative affective states may be associated with a general reduction in activity and feeding motivation reflecting a response bias rather than a judgement bias (Brilot et al, 2010).…”

“…In a number of species, behavioral cues are used to assess stressful situations as in novel or sudden situations [8][9][10]. For instance, alertness postures are considered to be a passive stress response in mammals [11,12]. Moreover horses fed a diet low in fiber and high in grain have a greater risk of developing stereotypic behaviors such as cribbing, circling the stall and weaving [13].…”
