Evaluating the physical welfare of dogs in commercial breeding facilities in the United States
out of 5 stars
Contributor(s):: Moriah J. Hurt, Candace Croney (adviser)
Despite high levels of public concern, the state of commercial breeding (CB) dog welfare is largely unknown. Therefore, this study aimed to characterize the physical welfare of dogs in CB facilities and their environment in Indiana. This study specifically aimed 1) to characterize dog foot...
Using the Horse Grimace Scale (HGS) to Assess Pain Associated with Acute Laminitis in Horses (Equus caballus)
Contributor(s):: Katie Carroll, Emanuela Dalla Costa, Diana Stucke, Francesca Dai, Michela Minero, Matthew C. Leach, Dirk Lebelt
Acute laminitis is a common equine disease characterized by intense foot pain, both acutely and chronically. The Obel grading system is the most widely accepted method for describing the severity of laminitis by equine practitioners, however this method requires movement (walk and trot) of the...
Can automated measures of lying time help assess lameness and leg lesions on tie-stall dairy farms?
Contributor(s):: Charlton, G. L., Bouffard, V., Gibbons, J., Vasseur, E., Haley, D. B., Pellerin, D., Rushen, J., Passille, A. M. de
The time that dairy cows spend lying down is an important measure of their comfort and lameness and injuries to hocks and knees are associated with alterations in lying time. We examined whether automated measures of lying time could identify cows and farms with problems of lameness or leg...
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...

Environmental complexity and use of space in slow growing free range chickens
Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.
Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...
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...
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...
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,...
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...
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...
Management practices associated with owner-reported stable-related and handling behaviour problems in UK leisure horses
Contributor(s):: Hockenhull, J., Creighton, E.
Stable-related and handling behaviour problems are highly prevalent in UK leisure horses. Associations between routine management practices and behaviour problems have been identified in racehorses and performance horses but it is unknown whether these practices are also associated with...
Pre-feeding behaviour in UK leisure horses and associated feeding routine risk factors
Many horses display unwanted behaviour prior to receiving concentrate feed or forage. These behaviours have received relatively little scientific attention as a distinct group of equine behaviour problems and risk factors for their performance have not been quantified. The objective of this...
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...
Equine stereotypic behaviors: causation, occurrence, and prevention
Contributor(s):: Sarrafchi, A., Blokhuis, H. J.
There are strong suggestions that equine stereotypies are connected to poor welfare and a suboptimal management and/or stabling environment. Different forms of equine stereotypic behaviors have been described. Crib biting, weaving, and box walking are considered the most prevalent. Several...
Relationships between young stallions' temperament and their behavioral reactions during standardized veterinary examinations
Contributor(s):: Peeters, M., Verwilghen, D., Serteyn, D., Vandenheede, M.
Horse handling and veterinary examination can induce hazardous stress reactions. Such reactions occur especially in young and less-trained horses, particularly stallions, and make their handling a risk for breeders, grooms, and medical staff. Moreover, these stressful situations will affect the...
Status quo of the personality trait evaluation in horse breeding: judges' assessment of the situation and strategies for improvement
Contributor(s):: Borstel, U. K. von, Pasing, S., Gauly, M., Christmann, L.
Recently, concerns about the validity of the evaluation of personality traits in horse breeding have been raised. For that reason, the aim of the present study was to assess the current status of personality trait evaluation in horse breeding. A survey was conducted among all station performance...
Training horses: positive reinforcement, positive punishment, and ridden behavior problems
An Internet survey was used to investigate the relationship between riders' responses to their horse's behavior in 8 commonly encountered riding scenarios and the frequency of generic behavior problems displayed by their horse during ridden work. There was a significant negative correlation...
