A comparison of positive reinforcement training techniques in owl and squirrel monkeys: time required to train to reliability
Contributor(s):: Rogge, J., Sherenco, K., Malling, R., Thiele, E., Lambeth, S., Schapiro, S., Williams, L.
Positive reinforcement training (PRT) techniques enhance the psychological well being of nonhuman primates by increasing the animal's control over his or her environment and desensitizing the animal to stressful stimuli. However, the literature on PRT in neotropical primates is limited. Here PRT...
A cross-sectional study of prevalence and risk factors for foot lesions and abnormal posture in lactating sows on commercial farms in England
Contributor(s):: Kilbride, A. L., Gillman, C. E., Green, L. E.
A cross-sectional study of lactating sows in 71 commercial pig herds in England was carried out to estimate the prevalence of foot lesions and abnormal posture and investigate the associated risks. Observational data were collected on the standing posture, lesions on the hind left foot, and the...

A retrospective survey of riders' opinions of the use of saddle pads in horses
Contributor(s):: Hawson, L. A., McLean, A. N., McGreevy, P. D.
Horse riders have used layers between saddles and their horse's back since ancient times. Despite the apparent common usage of such layers, most research regarding pressures under horses' saddles seems to have been conducted without such layers present. An online survey of equestrian riders was...
A survey of elephant husbandry and foot health in North American zoos. (Special Issue: The care and welfare of elephants in AZA institutions.)
Contributor(s):: Lewis, K. D., Shepherdson, D. J., Owens, T. M., Keele, M.
The foot health of elephants in human care is a longstanding concern. In 2001, the AZA Standards for Elephant Management and Care were published recommending husbandry to improve foot health. This article reports the results of a 2006 survey: basic statistics describing facility, husbandry, and...

Assessing the rider's seat and horse's behavior: difficulties and perspectives. (Special Issue: Equitation science.)
Contributor(s):: Blokhuis, M. Z., Aronsson, A., Hartmann, E., Reenen, C. G. van, Keeling, L.
A correct seat and position are the basis for a good performance in horseback riding. This study aimed to measure deviations from the correct seat, test a seat improvement program (dismounted exercises), and investigate whether horse behaviour was affected by the rider's seat. Five experienced...
Associations between lesion-specific lameness and the milk yield of 1,635 dairy cows from seven herds in the Xth region of Chile and implications for management of lame dairy cows worldwide
Contributor(s):: Green, L. E., Borkert, J., Monti, G., Tadich, N.
Lameness is one of the greatest infringements of welfare in dairy cows. The objective of this study was to investigate associations between milk yield and foot lesions causing lameness in Chilean dairy cattle with the hypothesis that if we can demonstrate that lameness reduces yield, and so...
Behavioural and physiological consequences of capture for shearing of vicunas in Argentina
Contributor(s):: Arzamendia, Y., Bonacic, C., Vila, B.
Behavioural, physical and physiological responses of Argentinean vicunas to capture, handling and shearing were studied for the first time. The research was undertaken in a study area of 2414 ha with a mean density of 12-40 vicunas/km2. Captures were conducted on groups of wild vicunas that had...
Boots on horses: limb protection or hyperflexion training aids in the showjumping horse. (Special Issue: Equitation science.)
Contributor(s):: Murphy, J.
Showjumping riders regularly employ various schooling strategies to control the horse's jump stride kinematics (JSK). Strategies include plyometric training regimes with fences of different heights and widths set at specific distances. Gymnastic grids teach the horse to jump cleanly. Rapping,...
Changes in leg health, skin, and plumage condition in domestic male turkeys of varying body weights
Contributor(s):: Dalton, Hillary A., Wood, Benjamin J., Widowski, Tina M., Guerin, Michele T., Torrey, Stephanie
Injurious pecking in turkeys is a serious welfare and economic concern in commercial production. Yet, very little is known about the development of this behaviour, and whether it relates to physical characteristics of the turkey. The objective of this study was to investigate the relationships...

Development of a facial expression scale using footrot and mastitis as models of pain in sheep
Contributor(s):: McLennan, Krista M., Rebelo, Carlos J. B., Corke, Murray J., Holmes, Mark A., Leach, Matthew C., Constantino-Casas, Fernando
Management of pain in sheep is limited by the challenges of recognising and accurately quantifying pain in this species. The use of facial expression scoring to assess pain is a well-utilised, practical tool in both humans and non-human animals. The objective of this study was to develop a...
Difficulty of cross-country obstacles for horses competing in three day events
Contributor(s):: Stachurska, A., Pieta, M., Ussing, A. P., Kapron, A., Kwiecinska, N.
The objective of the study was to determine which cross-country obstacles are more difficult for eventing horses. Jumping scores were considered in terms of the horse's reaction to novelty and to the fearfulness of novel objects which are the fences situated in novel terrain. The data concerned...
Distribution, complications, and outcome of footpad injuries in pet and military working dogs
Contributor(s):: Hansen, L. A., Hazenfield, K. M., Olea-Popelka, F., Smeak, D. D.
This study reports the findings of 120 traumatic pad injuries in pet and military dogs. Most dogs (68%) presented with a laceration to a thoracic limb footpad, and one-third of dogs were middle-aged castrated males. Metacarpal pads were most commonly injured. Short-term complications were noted...

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...
Effect of breed, cage type, and reproductive phase on fecal corticosterone levels in doe rabbits
Contributor(s):: Prola, L., Cornale, P., Renna, M., Macchi, E., Perona, G., Mimosi, A.
Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of...

Contributor(s):: Rosell, J. M., Fuente, L. F. de la
Ulcerative pododermatitis or sore hocks is a common condition in adult rabbits housed in cages with wire-mesh floors. This study was carried out on a recently-opened commercial farm with 224 breeding cages (112 without footrests [NFR] and 112 with footrests [FR]) to assess the effect of footrests...
