The effects of a breathing condition in thoroughbred and tall horses is set to be reduced by new University of Queensland treatment techniques. School of Veterinary Science equine surgeon Ben Ahern is investigating treatments for laryngeal hemiplegia, a degenerative condition known as “roaring” that restricts oxygen intake during exercise in […]
Horses engaged in strenuous exercise display physiological responses that approach the upper functional limits of key organ systems, in particular their cardiorespiratory systems. Maximum athletic performance is therefore vulnerable to factors that diminish these functional capacities, and such impairment might also lead to horses experiencing unpleasant respiratory sensations, i.e., breathlessness. […]
A welfare issue for horses fitted with tight nosebands has been highlighted by new research from the University of Sydney’s Faculty of Veterinary Science. ‘The Effect of Noseband Tightening on Horses’ Behaviour, Eye Temperature, and Cardiac Responses’ was published in PLOS ONE journal in early May, and finds that horses […]
Thoroughbred jump racing sits in the spotlight of contemporary welfare and ethical debates about horse racing. In Australia, jump racing comprises hurdle and steeplechase races and has ceased in all but two states, Victoria and South Australia. This paper documents the size, geography, composition, and dynamics of Australian jump racing […]
The sarcomeric α-actinins, encoded by the genes ACTN2 and ACTN3, are major structural components of the Z-line and have high sequence similarity. α-Actinin-2 is present in all skeletal muscle fibres, while α-actinin-3 has developed specialized expression in only type 2 (fast, glycolytic) fibres. A common single nucleotide polymorphism (SNP) in […]
