The influence of age on qualitative and quantitative parameters of stallion ejaculate

Popis výsledku v původním jazyce

Qualitative and quantitative parameters of stallion ejaculate are influenced by various factors. The age of stallion is one of them. The aim of this study was to evaluate the effect of stallion age on the ejaculate gel-free volume, concentration, motility and sperm morphology. The total number of 15 stallions of various breeds housed in the Tlumačov Regional Stud Farm were included in this research. The total number of evaluated ejaculates was 103. Stallions were divided into three age categories (3-7 y, 10-14 y, 18-20 y). The highest values of ejaculate gel-free volume were reached by the group aged 10 to 14 years (57.33 ml) and the lowest values were reached by the group of the oldest stallions (34.17 ml) (p LESS-THAN OR EQUAL TO 0.05). Stallions from the age category 10-14 y also achieved the highest values of sperm concentration (254.21 * 106 / ml). The lowest sperm concentration was measured in the age group of the oldest stallions (197.07 * 106 / ml). The oldest age group (18-20 y) achieved the highest values of sperm motility (86.57%) while the lowest values were achieved within he youngest age group of stallions (79.27%). Differences in sperm concentration and motility were not statistically significant. The highest values of spermatozoa with normal morphology were reached by the oldest age group (89.64%), while the lowest values were reached by the youngest group from 3 to 7 years (85.22%) (p LESS-THAN OR EQUAL TO 0.05). The effect of age on ejaculate parameters was demonstrated in both sperm volume and morphology. Therefore, the age of the stallion should be taken into consideration when evaluating stallion ejaculate.
