Genetic analysis of haematological and plasma biochemical parameters in the Spanish purebred horse exercised on a treadmill

Abstract

The novel aim of this study was to describe the reference values of different haematological and biochemical parameters in the Spanish purebred horse (Andalusian, SPB) in each of the stages of a programmed exercise on a treadmill system, and to establish heritability and genetic correlations for these haematological and biochemical parameters. For this, 94 young SPB male horses (4.22 6 2.27 years old) were used. An increasing intensity exercise test at 4, 5, 6 and 7 m/s was carried out on a treadmill (6% inclination). Total red blood cells, total white blood cells, neutrophils and lymphocytes counts; haematocrit, haemoglobin, lactate, uric acid, creatinine and total plasma proteins concentrations and aspartate transaminase, lactate dehydrogenase, creatine-quinase activities were determined. To conclude: (i) the reference values for each parameter were determined for each of the exercise test stages (ii) all the parameters analysed manifested a medium-high heritability and a high repeatability. These results will, in the near future, determine the measuring guidelines for improving the SPB horse's athletic ability on an objective treadmill system and for selecting these animals in response to those parameters.

Hematologic and biochemical reference intervals for adult Friesian horses from North America

“…The Friesian breed trended toward higher LDH activities. This trend was also reported in the Spanish Andalusian breed, a potentially interesting finding considering the history of the Friesian breed. However, a higher RI for CK and AST activities in Andalusians were speculated to be related to the handling of the horses prior to sampling.…”

“…This can be true for many RI used by veterinarians. Few published studies report breed or type‐specific RI in horses, and older studies use obsolete analyzers so that comparisons to current studies cannot be made. Without further studies, differences in breed‐specific RI and the applicability of general RI to specific horse breeds are unknown.…”

Changes in plasma leptin concentration during different types of exercises performed by horses

“…The least intensive exercise was applied during the dressage training (group D). The relative intensity of exercise in horses can also be estimated on the basis of changes in some biochemical parameters, for example, LA and UA levels (Desmecht et al, 1996;Escribano et al, 2013). Generally, the post-exercise values of LA and UA correlate positively with the intensity of exercise (Desmecht et al, 1996;Castejón et al, 2006).…”

Research Trends in Biochemical Analysis

“…This improved cytoskeleton purification method will aid our understanding of how the cytoskeleton controls normal and diseased cell functions. Escribano and co-workers studied the reference values of different haematological and biochemical parameters in the Spanish Purebred horse (SPB, Andalusian) in each of the stages of a programmed exercise on a treadmill system [19]. Ninety four young SPB male horses (4.2 ± 2.3 years old) were used.…”
