Rollkur stress levels probed in horses

The FEI brought inwards rules inwards 2010 stating that the caput as well as cervix railroad vehicle of the Equus caballus should non hold upward held inwards a sustained or fixed seat for to a greater extent than than 10 minutes during warmup. © FEI

Ten minutes of “low-deep-and-round” may final result inwards acuate stress responses inwards horses, an equitation conference inwards Scotland has been told.

Dutch as well as Danish researchers, presenting at the tenth Equitation Science conference inwards Edinburgh,  have flora that, compared to other caput as well as cervix positions, horses ridden inwards hyperflexion, equally good known equally rollkur, or “low deep as well as round”, are probable to hold upward exposed to higher levels of physiological stress.

Previous studies explored the effects of the hyperflexed caput as well as cervix seat on the stress as well as behavioural responses of horses on the lunge or a treadmill.

This report measured a multifariousness of behavioural as well as physiological responses of horses ridden inwards hyperflexion as well as 2 other mutual caput as well as cervix positions.

Fifteen Danish dressage horses preparation at medium to Grand Prix grade as well as routinely ridden inwards the hyperflexed caput as well as cervix seat were used.

In add-on to depression deep as well as round, the researchers equally good investigated the criterion “on the bit”, or contest frame, as well as unloosen frame, inwards which at that spot is less tension inwards the reins.

Each passenger performed a pre-determined riding exam of 10 minutes duration inwards walk, trot as well as canter inwards each of the iii caput as well as cervix positions, randomised over the iii days of testing.

Heart rate, heart-rate variability, salivary cortisol concentration, behavior as well as the tension inwards reins were recorded during the 10-minute exam period. Salivary cortisol concentrations were measured sixty minutes earlier as well as lead after the test, equally good equally 5, xv as well as thirty minutes later.

“This report is the commencement to exam whether at that spot is an acuate stress reply to the hyperflexed caput as well as cervix seat inwards horses ridden inwards a typical preparation environment,” Dr Machteld van Dierendonck, from Utrecht University, told the conference, organised past times the International Society for Equitation Science.

“We flora that the increment inwards salivary cortisol concentrations from baseline were significantly higher after 10 minutes of riding inwards the hyperflexed seat than the increases observed inwards the contest caput seat or amongst the unloosen frame.”

Cortisol is known equally the “stress” hormone as well as increased cortisol concentrations are routinely used to quantify stress responses inwards brute welfare studies.

“We didn’t let on whatever pregnant differences inwards centre rate, as well as centre charge per unit of measurement variability betwixt the treatments, only nosotros did let on that certainly behaviours were higher during hyperflexed riding than the other caput positions.

“Rein tension during the hyperflexed as well as contest caput seat was significantly greater than during the unloosen frame position.

“Compared to previous studies which accept used side reins to keep the hyperflexed position, the low, deep as well as circular seat inwards this report was less hyperflexed.” she said.

“We wanted to exam the horses’ reply to this method inwards a typical preparation environment.

“Within the parameters of this preparation situation, nosotros flora that the purpose of the hyperflexed caput position, fifty-fifty inwards horses routinely ridden this means could final result inwards a physiological stress reply equally measured past times salivary cortisol concentrations.

“Interestingly, riders indicated a loss of residue as well as steering command inwards the unloosen frame.”

Head as well as cervix positions accept been the dependent champaign of controversy, amongst the FEI conducting 2 reviews inwards recent years.

This report was a articulation projection amongst Danish as well as Dutch universities. Janne Winter Christensen. from Aarhus University inwards Denmark, along amongst Mirjam van Dalum and Mandy Beekmans from Utrecht University were articulation researchers on the study.
