Greyhound Racing Track Lure Systems—Acoustical Measurements Within and Adjacent to the Starting Boxes

چکیده

This study investigates and compares the acoustic signatures of a traditional wire-cable-pulled lure system two alternative battery-operated systems jointly developed by Covey Associates Pty. Ltd. Steriline to eliminate hazardous steel-wire cable make sport greyhound racing safer for greyhounds, participants spectators. The acoustical measurements these three were conducted at Murray Bridge track. sounds measured high-frequency Brüel & Kjær (B&K) Type 4191 microphones 395 m 455 starts positions: within starting box on track adjacent boxes. capture that greyhounds hear before after opening gate. frequency-domain analysis sound quality compare sounds. It was found when battery-lure installed with all nylon rollers, it presented less energy lower frequency than lure. When rollers replaced steel emitted louder higher different characteristics suggest future research is warranted reaction sounds, particularly their excitement level as approaches. initial also suggests some may not clearly approaching boxes timing jump be delayed, during high wind conditions.

Thromboelastographic tracings in retired racing greyhounds and in non-greyhound dogs.

BACKGROUND Bleeding disorders in patients with normal coagulation test results are frequently reported in Greyhounds. The purpose of this study was to compare Greyhounds to non-Greyhounds by thromboelastography (TEG). HYPOTHESIS TEG parameters in Greyhounds are different from those in non-Greyhounds. ANIMALS Forty-three healthy dogs (28 Greyhounds and 15 non-Greyhounds) based on the results...

High speed galloping in the cheetah (Acinonyx jubatus) and the racing greyhound (Canis familiaris): spatio-temporal and kinetic characteristics.

The cheetah and racing greyhound are of a similar size and gross morphology and yet the cheetah is able to achieve a far higher top speed. We compared the kinematics and kinetics of galloping in the cheetah and greyhound to investigate how the cheetah can attain such remarkable maximum speeds. This also presented an opportunity to investigate some of the potential limits to maximum running spee...
