Abstracts: Physical health problems and environmental challenges influence balancing behaviour in laying hens

With rising public concern for animal welfare, many major food chains and restaurants are changing their policies, strictly buying their eggs from non-cage producers. However, with the additional space in these cage-free systems to perform natural behaviours and movements comes the risk of injury. We evaluated the ability to maintain balance in adult laying hens with health problems (footpad dermatitis, keel damage, poor wing feather cover; n = 15) using a series of environmental challenges and compared such abilities with those of healthy birds (n = 5).

Abstracts: Pathogenesis of osteochondrosis dissecans: How does this translate to management of the clinical case?

Osteochondrosis (OC) is the most prevalent developmental orthopaedic disease in the horse. It is a complex disorder because of the interplay of factors that influence the formation of lesions and the ensuing natural healing process, the end result of which determines clinical outcome. The early pathogenetic mechanism of OC has long remained elusive, but recent research . . . → Read More: Abstracts: Pathogenesis of osteochondrosis dissecans: How does this translate to management of the clinical case?

Abstracts: Assessing positive emotional states in dogs using heart rate and heart rate variability

Since most animal species have been recognised as sentient beings, emotional state may be a good indicator of welfare in animals. The goal of this study was to manipulate the environment of nine beagle research dogs to highlight physiological responses indicative of different emotional experiences. Stimuli were selected to be a more or a less positive food (meatball or food pellet) or social reward (familiar person or less familiar person). That all the stimuli were positive and of different reward value was confirmed in a runway motivation test. Dogs were tested individually while standing facing a display theatre where the different stimuli could be shown by lifting a shutter.

Abstracts: Pedicle ties provide a rapid and safe method for feline ovariohysterectomy

Objectives: The specific objectives of the present study were to evaluate the rate of hemorrhage-related complications across a large number of feline pedicle tie (PT) procedures, and evaluate for a difference in surgical time between traditional pedicle double ligation (PDL) and PT procedures.

Methods: In the initial phase of the study, 2136 intact female cats underwent an . . . → Read More: Abstracts: Pedicle ties provide a rapid and safe method for feline ovariohysterectomy

Abstracts: Canine oral mucosal mast cell tumours

Mast cell tumours (MCTs) are the most common cutaneous tumours of dogs, however rarely they can arise from the oral mucosa. This subset of MCT is reported to demonstrate a more aggressive clinical course than those tumours on the haired skin and the authors hypothesised that dogs with oral, mucosal MCT would have a high incidence of local lymph node metastasis at presentation and that this would be a negative prognostic factor. An additional hypothesis was that mitotic index (MI) would be prognostic. Continue reading Abstracts: Canine oral mucosal mast cell tumours
