60 unresolved questions extracted from the limitations and future-work sections of 268 Animal Behavior and Welfare Studies papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The study notes that the elevated standing time under red light may indicate increased alertness or insufficient resting comfort, warranting further investigation. The study also notes that the frequent occurrence of 'no ingestion' under welfare-friendly lighting may indicate inactivity or discomfort.

    Behavioral Responses to Welfare-Friendly Lighting Management in Dairy Cows: A Comparative Study · 2026 · DOI

  • The study identifies a gap in the understanding of the effects of welfare-friendly lighting management on the behavioral patterns of prepartum Holstein cows. The study notes that prior work has focused on the effects of lighting on milk production, but not on cow welfare.

  • Inadequate living conditions and lack of healthcare in zoos. Limited inter-zoo data interoperability and the risk of single-point data failure in centralized cloud-based databases.

  • The lack of readily available ethograms for many species. The difficulty in assessing quantifiable components in definitions. The need for more accurate and reliable methods for behaviour identification.

    Strategies for improving the quality and accessibility of captive animal ethograms · 2026 · DOI

  • The study had a limited sample size of 28 rabbits. The study only evaluated the effects of RAP on rabbits exposed to a novel environment. The study did not investigate the long-term effects of RAP on rabbit behavior.

  • Further research is needed to investigate the long-term effects of RAP on rabbit behavior. The study's findings could be applied to other animal species. Further research is needed to explore the use of RAP in laboratory and agricultural settings.

  • There is no EU legislation specifically dedicated to the welfare of working equids.

  • Research has paid little attention to tail biting in weaner pig production. There is a need to investigate the impact of motivational factors and economic incentives on the management of tail biting.

  • Although genetic selection for mothering ability has improved piglet survival, the behavioral traits underlying this effect remain poorly understood.

  • While controlled research has identified best practices for managing weaning, little is known about how calves cope with weaning on commercial dairy farms.

  • The paper acknowledges that understanding the functions and mechanisms of affects will evolve and inform affect profile construction, yet provides no framework for how existing affect profiles should be updated, revised, or versioned as new mechanistic understanding emerges, or how inconsistencies between revised profiles and previous welfare decisions should be managed.

    Mapping profiles of animal affect · 2026 · DOI

  • The paper argues that a two-dimensional affective space (arousal and valence) is insufficient for guiding welfare interventions because it cannot identify species-specific affective experiences to avoid or promote, but does not empirically demonstrate or test whether affect profiles constructed through the proposed dimensional approach provide superior predictive validity for actual welfare outcomes.

  • CHALLENGES AND TECHNICAL 5.1 Technical and Hardware Limitations Despite advances, automated monitoring systems still face technical limitations. RFID tracking can miss detections during rapid movement, leading to to and and beam capture alignment gaps and underestimation of activity [1]. Its spatial resolution is also limited by antenna density, yielding discrete rather than continuous position data [1]. Infrared beam-break systems are robust and widely used, but they provide coarse spatial information detailed cannot repertoires [2], [14]. They are behavioural sensitive cage configuration, which can affect measurement consistency [1]. Additionally, these systems can only categorize basic movements, such as ambulatory versus vertical activity [2]. Video-based systems face challenges related to lighting conditions, occlusion, and image quality [12], [30]. Nesting material, bedding, and cage enrichment items can obscure animals from camera view, impeding accurate tracking and behavioural classification [30]. In group-housed settings, overlapping or closely positioned animals create ambiguity for tracking algorithms, making behavioural individual attribution additional identification methods [30].

  • Future research should focus on expanding dataset coverage and establishing unified evaluation splits. Future research should develop highly generalizable model architectures and cross-modal deep learning frameworks.

    Computer vision-based livestock weight measurement: principles, methods, and challenges · 2026 · DOI

  • The scarcity of high-quality labeled datasets is a research gap. Variations in animal posture under dynamic conditions are a research gap. Environmental interference is a research gap.

  • The study suggests the need for future prospective studies with greater specificity in identifying the causes of culling. The research highlights the importance of optimizing both pasture-based and confined systems to achieve sustainable outcomes.

    Causes of culling in dairy cows in the central region of Santa Fe, Argentina · 2026 · DOI

  • The study identifies a lack of standardized classification criteria and nomenclature for studying the causes of culling in dairy cows in Argentina. The research highlights the need for more specific and detailed studies on the causes of culling in dairy cows.

  • The need for a review of the use of cortisol as a biomarker of stress in animals. The need for a discussion of the strengths and challenges associated with different cortisol sampling methods. The need to highlight the importance of multiple biological sample approaches for accurate welfare assessments in ruminants.

  • The study only collected data from human subjects, with no direct data collected about the animals. The sample size was limited to 41 dairy farmers and 7 extensionists.

    Gender inequality and animal welfare intersections in family dairy farming · 2026 · DOI

  • Future research should continue to explore the implications of gender differences for animal welfare. Studies should investigate the impact of gender on the design and implementation of animal welfare initiatives. Research should examine the effectiveness of training programs aimed at improving animal welfare in dairy farming.

  • Current models rely on over-parameterization, increasing computational burden. Imbalanced behavioral categories affect classification accuracy. Dense distribution of Hu sheep poses detection challenges.

  • The current system for managing animal health data is inadequate. There is a need for a secure, transparent, and tamper-proof mechanism for recording and exchanging animal health information.

    Tracking Animal Health in Zoos Using Blockchain Technology · 2026 · DOI

  • There is currently no systematic framework to guide decisions about compensating animals. Current assessments of how harms and benefits combine in animal lives are too often based on human intuition.

    Compensating animals through the reduction and positive redress of welfare harms · 2026 · DOI

  • Finally, further work is needed to evalu- ate humans’ motivations and capacities to compensate (including the symbolic value of compensation), and how to encourage and support decision-makers and practitioners to provide compensation across laboratory, breeding, farming, veterinary and other con- texts.

  • The study identifies a gap in the understanding of the effect of melatonin administration on oxidative stress and blood parameters in sheep during shearing.
