Is the Piglet Grimace Scale (PGS) a useful welfare indicator to assess pain after cryptorchidectomy in growing pigs?

Pig cryptorchidism is a congenital anomaly, which requires surgical intervention. Pain assessment in pig farming has some limitations and consumers are increasingly concerned about suffering linked to on-farm procedures. The PGS seems to be a promising tool for pain assessment...

Tortoise Husbandry and Welfare

Keeping captive tortoises healthy and well is a significant challenge. Because they are ectotherms, these reptiles are totally dependent upon external sources to maintain body temperature and therefore metabolic function. Their physical environment is vital for them to remain healthy,...

Quantifying the cumulative impact of use in teaching and research: An initial assessment of an objective tool developed to safeguard working horse welfare in a university setting

Universities offering veterinary and equine science education typically keep horses to support teaching and research activities. The Australian Code requires approval of horse use by an independent Animal Ethics Committee and that cumulative use over an individual’s working lifetime is...

Non-invasive ultrasound measurements for determination of hepato-somatic index in Greenland halibut (Reinhardtius hippoglossoides)

Hepato-somatic index (HSI) is widely used to indicate fish body condition and level of energy reserves related to feeding/physiology and reproduction. HSI is traditionally obtained by dissection and measurement of liver mass versus body mass, but ultrasound technology may provide...

Novel application of machine learning to enhance untrained and inexperienced evaluators’ diagnosis of acute pain in pigs

Accurately identifying pain is a critical first step required to adequately mitigate pain and improve pig health, welfare and quality of life. The objective of this study was to verify whether random forest and support vector machine algorithms trained utilizing...

Advancing canine welfare assessment in kennels: Evaluating the validity of Field Instantaneous Dog Observation (FIDO) scoring in commercial breeding kennels

Accurate assessment of social fear in dogs housed in commercial breeding kennels is necessary to inform their behavioral management, including interventions needed to support their welfare. The Field Instantaneous Dog Observation (FIDO) tool, which was developed to quickly identify areas...

Do the ear and tail positions reflect the emotional state of calves?

This study aimed to determine the associations between ear and tail position and stroking or umbrella stimuli in dairy calves at different stimulus application times (before the test, pretest, test, and posttest). Thirty-two mixedbred Holstein calves of different ages were...

Quantification of sea turtle swimming patterns using a standardized arena to minimize effort in welfare assessment

Welfare assessment of captive sea turtles has become increasingly important as the need for lifelong care grows. The most valuable indicator of sea turtle welfare is behavioral assessment, as it is non-invasive and more cost-effective than other methods such as...

The challenge of identifying positive emotional indicators in equids: A scoping review to evaluate if this approach is putting the cart before the horse (Equus caballus)

Driven by multiple converging factors, highlighting the negative impact of equestrian sports on equine welfare, recent scientific research has focussed on recognising positive states in horses (Equus caballus). In particular, this has yielded an increasing number of studies prioritising the...
