Avaliação comparativa dos parâmetros fisiológicos e bioquímicos de equinos de Team penning seplementados com TONNUS JCR (Vetnil®)

Abstract

The search for horses for leisure and mainly, for sports practices has grown a lot in the past decades. Throughout centuries, horses were selected for their specific characteristics in several sport modalities, and exposed to the great variety of stressful challenges as: intensity and quantity of training, competitions, transportation, veterinary examinations and insertion into new groups of animals. Among equestrian sports, Team Peanning has been growing in Brazil. It is known to be a modality that requires a lot of technique, speed and agility from horses. In this type of exercise, which involves maximum velocity in a short period of time, the energy deposited in muscle fibers are rapidly consumed through anaerobic metabolization, favoring the synthesis of lactic acid and its products, which is the formation of lactate in the presence of ammonia and free radicals. These products, when accumulated in muscles, contribute to pH drop and consequent muscle injury. Lactate and glucose dosed with biochemical assessment, along with measurement of some standard physiological parameters, show possible metabolic alterations that may reflect cardiovascular capacity, metabolic and exercise intensity, and these directly interfere in the equine athletic potential. The evaluation of physiological parameters, cardiac and respiratory frequency, temperature and mucoses, followed by monitoring of serum lactate and serum levels of CK, AST and LDH enzymes reflect the metabolic status and athletic potential of horses. The feeding supplementation aims to complement the energetic and mineral food requirements, assisting on the reduction of muscular injuries and better utilization of the energy in the metabolism of the animals. This work evaluated CK, AST, LDH, lactate and glucose were evaluated in 10 horses, quarter-mile, conditioned to the sporting modality Team penning, supplemented or not with Tonnus JCR, with the objective of evaluating the influence of this supplementation on the athletic potential of these animals.
