The effect of the stable environment and age on the semen production in the Czech Fleckvieh bulls

Popis výsledku v původním jazyce

The objective of this study is to evaluate the effect of stable environment and age on semen production in the Czech Fleckvieh bulls. During the period from March 2014 to August 2014, semen samples (n = 232) were collected using an artificial vagina. Immediately after collection, laboratory examinations were made for all samples, which included finding out ejaculate volume, sperm concentration and total sperm count. Ejaculate volume was measured using the graduated tube and sperm concentration was determined using a spectrophotometer. Total sperm count was calculated by multiplying ejaculate volume by sperm concentration. For statistic evaluation of the effect of stable environment, the average values of THI1 (temperature-humidity index from the one day before semen collection) were used and the bulls were divided into the groups according to the age. Monitored characteristics were expressed in weighted average and standard error. The effect of the stable environment and age on bovine
