Roaring

New research has pinpointed genes associated with a disease seen as a major contributor to poor performance in Thoroughbred racehorses, University College Dublin (UCD) announced on Tuesday. Hailed as a breakthrough in combatting the equine performance-limiting disorder Recurrent Laryngeal Neuropathy (RLN)--often referred to as laryngeal hemiplegia or 'roaring'--the discovery will enable the development of a genetic test to identify horses with a three-times higher risk of developing the disease. It currently affects up to 18% of horses by acting on the muscles in their upper airways, resulting in reduced airflow...

In this continuing series, we take a look ahead at US-bred and/or conceived runners entered for the upcoming weekend at the tracks on the Japan Racing Association circuit, with a focus on pedigree and/or performance in the sales ring. Plenty of activity this weekend, so we'll begin with Saturday's runners at Tokyo and Chukyo, where the promising Careerism (Upstart) will try to build on an impressive maiden victory from three weeks ago: 4th-CKO, ¥9,680,000 ($88k), Maiden, 3yo, 1400mT ROARING (f, 3, California Chrome--Warbling, by Unbridled's Song) looks to become the...
