An exploration of surface temperature asymmetries as potential markers of affective states in calves experiencing or observing disbudding.

The emotional valence hypothesis suggests an increased left-brain hemisphere activation during positive situations and during negative situations. Since facial thermal asymmetries may reflect lateralised brain activity, we investigated this in dairy calves subjected to hot-iron disbudding (Disbudded; n = 12) as a model of negative affective states. As affective responses can vary due to previous experiences, we examined whether calves that had (ExpObs; n = 12) and had not (InexObs; n = 12) experienced disbudding differed in their thermal response to a conspecific being disbudded, and whether calf response to the researcher (approaching, moving away, not moving) was associated with thermal asymmetries.

Genomic epidemiology of third-generation cephalosporin-resistant from Argentinian pig and dairy farms reveals animal-specific patterns of co-resistance and resistance mechanisms.

Unlabelled: Control measures are being introduced globally to reduce the prevalence of antibiotic resistance (ABR) in bacteria on farms. However, little is known about the current prevalence and molecular ecology of ABR in bacterial species with the potential to be key opportunistic human pathogens, such as on South American farms. Working with 30 dairy cattle farms and 40 pig farms across two provinces in central-eastern Argentina, we report a comprehensive genomic analysis of third-generation cephalosporin-resistant (3GC-R) , which were recovered from 34.

Do you see what I see? Testing horses' ability to recognise real-life objects from 2D computer projections.

The use of 2-dimensional representations (e.g. photographs or digital images) of real-life physical objects has been an important tool in studies of animal cognition.
