Welfare consequences of omitting beak trimming in barn layers

Beak trimming is used worldwide as a method of reducing the damage to feathers and skin caused by injurious pecking in laying hens. However, beak trimming also causes some welfare issues as trimming the beak results in pain and sensory...

A high enrichment replenishment rate reduces damaging behaviors and increases growth rate in undocked pigs kept in fully slatted pens

One of the difficulties in complying with the prohibition of routine tail docking is a lack of effective alternative solutions to prevent tail biting, especially in fully slatted systems. This study compared three slat-compatible enrichment replenishment strategies for pigs. Forty-eight...

Development of a donkey grimace scale to recognize pain in donkeys (Equus asinus) post castration

The objectives of this study were to establish a donkey ethogram, followed by a donkey grimace scale to be applied to donkeys pre- and post-castration and to test if there was a notable difference in scores based on observer knowledge,...

Effects of the method of restraint for shearing on behaviour and heart rate variability in alpacas

Alpacas are increasingly kept in Europe for different purposes including fibre production. Yearly shearing is necessary to harvest fibre and for welfare reasons. Different methods of restraint are used during shearing, which may affect the welfare of the animals differently....

Pessimistic dairy calves are more vulnerable to pain-induced anhedonia

Pain induces deficits in appreciation of rewards (i.e. anhedonia) and variation in response to pain may be partly explained by individual differences in general expectations (i.e. optimism). Dairy calves are routinely subjected to painful procedures such as hot-iron disbudding. We...

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...

Pain and pessimism affect calves’ play behaviours post-disbudding

Calves are expected to play less when in pain, and more pessimistic individuals may be more affected by painful events, such as hot-iron disbudding (i.e., horn-bud removal). We explored 1) the impact of disbudding on different play behaviours, predicting that...

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...

Efficacy of pain management for cattle castration: A systematic review and meta-analysis

Much research has assessed methods of pain control for cattle castration, but there remains a lack of consensus regarding best practice. We conducted a systematic review and meta-analysis of published research including both an untreated control (i.e. castrated without pain...

Assessing the welfare of spiny lobsters and true lobsters in aquaria: Biology-informed best-practice guidelines for captive conditions

The welfare of decapod crustaceans held in captivity, whether in aquariums, holding facilities, seafood restaurants, supermarkets, or fishmongers, is attracting growing attention and concern. This review focuses on three species that are commonly found in European commercial environments: the European...
