Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour
Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.
Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...
Producer or purchaser: different expectations may lead to equine wastage and welfare concerns. (Special Issue: Equitation science.)
Contributor(s):: Hennessy, K. D., Quinn, K. M., Murphy, J.
Horses are individual, each having differential characteristics such as height, colour, breeding, conformation, and temperament. These bio-characteristics often influence potential purchasers when buying horses. This study sought to investigate if producers and potential purchasers placed similar...

Chronic neurophysiological and anatomical changes associated with infrared beak treatment and their implications for laying hen welfare

Do dog owners perceive the clinical signs related to conformational inherited disorders as 'normal' for the breed? A potential constraint to improving canine welfare

Assessment of sheep welfare using on-farm registrations and performance data
Contributor(s):: Stubsjoen, S. M., Hektoen, L., Valle, P. S., Janczak, A. M., Zanella, A. J.
Farm animal welfare is a societal concern, and the need exists for scientific protocols to assess welfare. This paper describes the development of a protocol to assess the welfare of sheep (Ovis aries) and its application in 36 farms in Norway. There were two parts to the protocol; the animal-...
Breeding for quality of life
Contributor(s):: McGreevy, P. D.
Many breeds of companion animal have inherited disorders that may impair quality of life (QoL) to the extent that it is unkind to keep them alive. If we struggle to discern when this point is reached, why do we breed compromised, short-lived animals in the first place? If we struggle to judge...
Challenges and paradoxes in the companion-animal niche
Contributor(s):: McGreevy, P. D., Bennett, P. C.
By definition, the companion-animal niche demands merely that animals must provide companionship. At first glance, this may seem easy enough, but the forces that contribute to success in this niche are complex. Indeed, success as a companion is rarely measured in terms of biological fitness, and...
Does rubber flooring improve welfare and production in growing bulls in fully slatted floor pens?
Contributor(s):: Graunke, K. L., Telezhenko, E., Hessle, A., Bergsten, C., Loberg, J. M.
This study compared the effects of concrete slats (CS), synthetic rubber slats on aluminium profiles (RS) and slotted rubber mats on concrete slats (RM) in fully slatted floor pens on behaviour, claw and leg disorders, claw horn growth, cleanliness and production parameters of growing dairy bulls...
Early detection of lameness in heifers with hairy heel warts using a pressure plate
Contributor(s):: Almeida, P. E., Mullineaux, D. R., Raphael, W., Wickens, C., Zanella, A. J.
Lameness is an indicator of pain and suffering, which has substantial animal welfare and economic impact on the dairy industry. Subjective locomotion scoring is unreliable for detecting mild cases of lameness in dairy herds. Undetected lameness can progress to a more serious and painful state...
Long-term detrimental effects of tooth clipping or grinding in piglets: a histological approach
Contributor(s):: Hay, M., Rue, J., Sansac, C., Brunel, G., Prunier, A.
The needle teeth of piglets are often cut shortly after birth to prevent damage to littermates and the sow's udder. This practise is, however, contested because the pain it inflicts to piglets may counterbalance its benefits. The purpose of this experiment was to assess the consequences of tooth...
The effect of morphology on the musculoskeletal system of the modern broiler
Contributor(s):: Corr, S. A., Gentle, M. J., McCorquodale, C. C., Bennett, D.
This study compared various morphometric features of two strains of broilers, selected and 'relaxed' (ie random-bred), raised under two feeding regimes, ad-libitum-fed and restricted-fed. We consider the possible consequences of the different body shapes on the musculoskeletal system. The...
The use of a hand-held algometer as a method to measure mechanical nociceptive thresholds in sheep
Contributor(s):: Stubsjoen, S. M., Valle, P. S., Zanella, A. J.
The aim of this study was to explore the use of a hand-held algometer for the measurement of mechanical nociceptive thresholds (MNT) in sheep (Ovis aries). Twelve ewes were tested over three consecutive days by two operators, and MNTs were measured over six predetermined sites on both forelimbs...
Welfare epidemiology as a tool to assess the welfare impact of inherited defects on the pedigree dog population
Contributor(s):: Collins, L. M., Asher, L., Summers, J. F., Diesel, G., McGreevy, P. D.
The effect that breed standards and selective breeding practices have on the welfare of pedigree dogs has recently come under scrutiny from both the general public and scientific community. Recent research has suggested that breeding for particular aesthetic traits, such as tightly curled tails,...
What factors should determine cage sizes for primates in the laboratory?
Contributor(s):: Buchanan-Smith, H. M., Prescott, M. J., Cross, N. J.
It is imperative to provide adequate quantity and quality of space for all captive animals. Yet practically all guidelines on the housing of primates in the laboratory specify minimum cage sizes based solely on body weight. We argue that no single factor, such as body weight, is sufficient to...
The somatic sensory system
Contributor(s):: Kamerling, S. G.
The somatic sensory system provides information on bodily sensations. The status of an animal's internal and external environment is detected and interpreted by this system. Specialized receptors "transduce" the sensations of touch, pressure, temperature, and pain. Sensory impulses are...
