Blood biomarkers of the horse after field Vaquejada test

Metabolic and physiological changes during and after vaquejada exercise in horses

“…In the present study, the HR were close to those previously found with the use of a HR monitor with GPS, showing that pull horses reached a HRmax of ~210 bpm and helper horses ~196 bpm, with a Smax of ~9 m/s (Hunka et al, 2017), which was similar to other QH sports like reining and 3 barrels (Rammerstorfer et al, 1998;Kästner et al, 1999;Souza et al, 2018). In other studies with vaquejada horses, the HRmax reached approximately 100 bpm for pull and helper horses, with Smax similar to those of the present study, but this value was obtained using a stethoscope (Santiago et al, 2013;Azevedo et al, 2014;Souza et al, 2018), which it was not precise to determine HR during intense exercise. The utilization of the heart rate monitor makes this evaluation precise and the real-time data collected may be used to characterize the type of exercise by zone.…”

“…The vaquejada field test (VFT) was performed as described in the literature and followed the manual for good practice in equine sports and events (Hunka et al, 2017;BRASIL, 2017). Briefly, the VFT consisted of a pull and a helper horse running on a soft sand track (150 length) with a bovine, one cowboy and his horse gallop and work to pull the bull down (pull horse) and another cowboy and his horse (helper horse) help the first cowboy to keep the bull running in line (Santiago et al,2013). The pull horses (n=12) participated in one cycle (3 races).…”

“…Actually, the vaquejada is the most important equine sport in Brazil, and during this sport two horses and a bovine run on a sand track and simultaneously (Hunka et al, 2017). These horses are repeatedly submitted to short-duration physical exercise, during 2 or 3 alternate or consecutive days (Santiago et al, 2013;Hunka et al, 2017), requiring adequate conditioning for this equestrian modality. Thus, an experiment was developed to test the hypothesis that physiological, haematological and biochemical changes in pull and helper horses used in this equestrian modality would occur during and after their vaquejada, because their activity during the modality are different.…”

Efeito da suplementação com concentrados ricos em óleo sobre biomarcadores metabólicos para cavalos

“…A [GLIC] observada com os animais em jejum estava dentro da normalidade para a espécie (Ralston, 2008;Manso et al, 2015), assim como após seis horas da suplementação e assemelhava-se aos valores descritos na literatura para animais na região (Wanderley et al, 2010;Santiago et al, 2014). O pico da glicose também ocorreu, entre 120 e 180 minutos após a suplementação, de forma semelhante ao de outros trabalhos (Ralston e Baile, 1982;Healy et al, 1996;Witham e Stull, 1998 Barbosa et al (2016).…”

“…As ausências de variações significativas observadas nesses parâmetros eram esperadas tendo em vista que os animais consumiram água livremente ao longo do período de colheita de sangue, mas não receberam forragens, reduzindo assim o transporte de líquidos para o interior do trato digestivo. Os animais também foram mantidos estabulados, mas podendo interagir entre eles, em um ambiente calmo, livre de estresse ou que pudesse estimular a contração esplênica, que pode ocorrer em equinos submetidos ao exercício físico, como reportado por McKeever et al (2006) e Santiago et al (2014).…”
