Abstract |
The objectives were to
determine the effects of ambient
temperature, season, breed and age on spermogram of 13 AI sires
(3 Holstein, 5 Tarentaise and 5 Brune des Alpes) raised in Tunisia whose
age varied from 24 to 46 months and the body weight varied from 500 to
900 Kg. Study was undertaken from June 2007 to July 2008 on 654 fresh
ejaculates. Results showed that
volume, concentration and progressive motility decreased when
ambient temperature increased. However, when ambient temperature
increased, pH, percentages of live spermatozoa and major abnormalities
increased. Besides, there was no correlation between ambient
temperature, motility and minor abnormalities. There was a significant
difference (P<0.05) for volume and percentage of live spermatozoa
between the two classes of age. A significant difference existed between
seasons for the pH of Holstein
bulls and the concentration for Brune des Alpes bulls. Furthermore, pH,
concentration, motility and minor anomalies did not change (P<0.05)
within breeds. However, volume, percentage of live spermatozoa and major
and total anomalies of ejaculates varied between the three breeds.
