“…For instance, there is limited information regarding deck height and varying results regarding the benefits of unloading animals during a rest stop [ 35 , 36 , 38 , 39 , 128 ]. In addition, the development of measures that better reflect the animals' perspective (see [ 161 ]) may help determine the appropriate transportation conditions for different animal species. Based on precautionary reasoning about animal sentience by Birch [ 162 ], we suggest that where doubts exist or if there is a lack of scientific evidence, lawmakers should strive to adopt solutions that are most likely to protect the animals.…”

Growing animal welfare concerns have pushed some jurisdictions to strengthen regulations addressing live farm animal transportation, but whether they provide satisfactory levels of protection for animals remains to be shown. Using the recent peer-reviewed literature, we identified four major risk factors associated with live animal transportation (fitness for transport, journey duration, climatic conditions and space allowances) and explored how regulations were structured to prevent animal welfare issues in five English-speaking Western jurisdictions (Australia, Canada, New Zealand, the EU and the USA). All legally binding federal regulations were systematically reviewed and compared. Whether these rules were fit for purpose was assessed using the relevant peer-reviewed scientific literature. Our findings indicate the majority of regulations in most jurisdictions are often insufficient or too vague to be deemed fit for purpose. All five jurisdictions fall short in guaranteeing adequate protection to livestock during transport. Using recent changes as well as future policy proposals under discussion, we identify future directions that could form the basis for regulatory changes that may significantly improve the welfare of farm animals during transportation.

“…In previous studies using CPP in dairy calves, animals experienced a stimulus directly in the conditioning pen such as disbudding (Ede et al 2019b ), an analgesic injection to induce pain relief (Adcock & Tucker 2020 ), or transport (Creutzinger et al 2022 ). In the current study, the treatment was applied before conditioning (restricted vs enhanced diet) so that we could explore whether calves would associate a place with their level of satiation.…”

“…Methodological challenges faced here should encourage future studies using the CPP in calves to investigate whether the experimental design is vulnerable to biases due to colour, side preferences or other factors. For instance, Creutzinger et al ( 2022 ) studied calves’ response to transportation and a novelty bias was detected; calves preferred the pen in where they were not conditioned regardless of whether or not they were transported.…”

“…If animals are subjected to different experiences in different environments, they should prefer the environment associated with the most positive or least negative experience. This method, referred to as conditioned place preference (CPP), has been used in the past to study painful experiences such as disbudding in calves (Ede et al 2019a , b ; Adcock & Tucker 2020 ) and calves’ aversion for long-distance transportation (Creutzinger et al 2022 ), but has yet to be applied to other emotions.…”

Dairy calves are typically fed restricted amounts of milk. Although feed restrictions are predicted to result in negative affective states, the relative aversiveness of ‘hunger’ remains largely unexplored in this species. Here, we investigated whether the conditioned place preference paradigm can be used to explore how calves feel when experiencing different levels of satiation. This paradigm provides insight into what animals remember from past experiences, the assumption being that individuals will prefer places associated with more pleasant or less unpleasant experiences. Sixteen Holstein calves were either fed a restricted (3 L per meal totalling 6 L per day) or ‘enhanced’ milk allowance (ad libitum up to 6 L per meal totalling up to 12 L per day) in their home-pen. Calves were then placed in a conditioning pen for 4 h immediately after being fed their morning meal to allow them to develop an association between the pen and their state of post-prandial satiation. Calves were conditioned across four days with their satiation state alternating between days to allow them to develop an association between pen and satiation levels. On the 5th day, calves were individually allowed to roam freely between the two pens for 30 min. We expected that calves would prefer the pen where they previously experienced higher levels of satiation, but our results show no to limited effects of treatment. However, some methodological issues (colour and side bias) prevent us from drawing strong conclusions. We discuss reasons for these issues and potential solutions to avoid these in future studies.

“…More research is needed to exploit the great potential for determining the effect of water deprivation on bird welfare by using behavioral motivation tests, especially under transport conditions, where factors such as duration of water deprivation (using periods corresponding to typical transport durations, i.e., under 12 h), environmental conditions (particularly temperature and humidity), stocking density, and animal-based factors such as walking ability are considered. A recent study employing conditioned place aversion in dairy calves provides an example of how motivational testing may be used to assess affective states associated with transport conditions in livestock ( Creutzinger et al, 2022 ).…”
