Welfare assessment on pasture: A review on animal-based measures for ruminants

Outdoor and extensive farming systems allow animals to behave in a natural way and are often perceived as welfare friendly. Nonetheless, the natural environment poses multiple challenges to the welfare of animals, sometimes hampering their capacity to cope. Welfare assessment...

The power of a positive human–animal relationship for animal welfare

Domestic animals often seek and enjoy interacting with humans. Positive human–animal relationships can elicit positive emotions and other positive welfare outcomes. Nevertheless, our understanding of the underlying processes that govern the positive perception of humans by animals is incomplete. We...

Remote controlled nociceptive threshold testing systems in large animals

Nociceptive threshold (NT) testing is widely used for the study of pain and its alleviation. The end point is a normal behavioural response, which may be affected by restraint or unfamiliar surroundings, leading to erroneous data. Remotely controlled thermal and...

Attention bias test measures negative but not positive affect in sheep: A replication study

An attention bias test has been developed as a measure of negative affective states in sheep. The test measures an individual’s allocation of attention between a threatening (previous location of a dog) and positive (conspecific photo) stimulus over a 3...

Evaluation of infrared thermography as a non-invasive method of measuring the autonomic nervous response in sheep

Eye temperature measured using infrared thermography (IRT) can be used as a non-invasive measure of autonomic nervous system (ANS) activity in cattle. The objective of this study was to evaluate if changes in eye temperature (measured using IRT) can be...

How dietary diversity enhances hedonic and eudaimonic well-being in grazing ruminants

Ruminants evolved in diverse landscapes of which they utilized, by choice, a diverse arrangement of plants (grasses, forbs, and trees) for food. These plants provide them with both primary (carbohydrates, protein, etc.) and secondary (phenolics, terpenes, etc.) compounds (PPC and...

Preliminary findings on a novel behavioural approach for the assessment of pain and analgesia in lambs subject to routine husbandry procedures

The identification and assessment of pain in sheep under field conditions are important, but, due to their stoic nature, are fraught with many challenges. In Australia, various husbandry procedures that are documented to cause pain are routinely performed at lamb...

A case of thanatosis in domestic sheep

Thanatosis (feigning death, defensive tonic immobility) is a widespread anti-predator behavioural strategy in animals. Animals that have evolved this behaviour react to physical contact with the predator by displaying a persistent tonic immobility that makes them look like dead prey....

Comparison of dexmedetomidine/morphine and xylazine/morphine as premedication in isoflurane-anesthetized sheep

In this study we investigated the sedative, anesthetic, and pulmonary histopathologic effects of dexmedetomidine/morphine (DM) and xylazine/morphine (XM) in sheep. We hypothesized that DM would provide profound sedation and better maintain physiologic parameters under anesthesia than XM in sheep undergoing...

Dynamics of biochemical parameters, inflammatory and stress markers in lambs undergoing caudectomy using two different methods

Zootechnical practices such as tail docking are still in use in dairy sheep farming, performed in the first week of life, mainly by rubber ring and only rarely by surgical methods. In this study, we evaluated the impact of caudectomy...
