Determinación de la composición electrolítica antes y después del entrenamiento físico en equinos mestizos de la estación experimental Tunshi.

Abstract

The objective of this research was to determine the electrolyte composition before and after physical training in crossbred horses at the Tunshi Experimental Station. This study was developed in the Academic Unit of Equine Research with a duration of 8 weeks. The sample were 8 crossbred jumping horses under a schedule of activities. They were supplied with concentrate in a ratio of 1% of live weight taking into account the suggestions for high performance horses. This allowed to cover the nutritional requirements for maintenance and exercise. Training was carried out for 5 days (1 hour) to all horses equally in order not to alter the results. They were given a two-day rest. The T-Student test was applied with a significance at (P > 0.05) for electrolytes and physiological parameters while descriptive statistics for blood biochemistry in three repetitions on days (0, 7, 14). The results obtained in the electrolyte behavior were as follows: potassium from 3.95 to 3.60 mmol/L, sodium from 123.05 to 125.69 mmol/L, calcium from 3.20 to 3.14 mmol/L, phosphorus from 3.35 to 3.48 mg/ml and finally magnesium with 1.60 to 1.33 mg/dl. In the same way the physiological parameters presented highly significant differences which were within normal ranges. It is concluded that the electrolytes most lost by equines are potassium, calcium and magnesium. Therefore, it is recommended to provide a balanced diet for high performance equines and water to replace fluids lost after sweating.
