Medición del lactato sanguíneo en caballos con diferentes tiempos de entrenamiento en la estación experimental Tunshi.

Abstract

The objective of this research was to measure blood lactate concentration in horses. It was carried out at the Tunshi Experimental Station, within the Equine Research and Academic Unit. Eight Anglo-Arabian crossbred horses from four to twelve years old, with an estimated weight of 400 to 450 kilograms, between males and females, were used. A completely randomized design was applied in a two-factor combinatorial arrangement, using 4 repetitions and the size of the experimental unit was 1 equine per treatment, which were evaluated at different training times T1 (30 minutes), T2 (60 minutes), T3 (90 minutes) and T4 (120 minutes), taking blood samples after having finished the stress test; unlike T0, samples were taken from the untrained equines. The experimental results were subjected to an analysis of variance (ADEVA) and separation of means by TUKEY with a significance level (P > 0.05), comparing the lactate levels obtained highly significant differences were determined between treatments, it was observed that the blood lactate concentration of equines in training is from 1.242 to 1.764 mmol /L, therefore, it was concluded that T1 (1, 76 mmol/ L) and T2 (1.74 mmol/L) present high lactate concentrations, therefore blood lactate levels are not altered by the sex of the horses but by the training tempo, in this way it is recommended to evaluate parameters such as heart rate and respiratory rate that allows to rule out the increase of blood lactate concentration in equines during the training and competition period.
