ABSTRACT

The aim of study was to examine the effect of bulls breed
and collection month on characteristics of ejaculates: volume, concentration
of spermatozoa, wave motion, percentage of live sperm in the ejaculate and percent
of morphological defects of spermatozoa. The investigation was carried out on
the 3454 beef bulls ejaculates collected from the following breeds: Limousine,
Simmental, Piemontese, Charolaise, Blonde d’Aquitaine. Results reviled
that breed and collection month significantly influenced volume, concentration
of spermatozoa, wave motion, percentage of live sperm in the ejaculate and percent
of morphological defects of spermatozoa obtained from beef bulls used for insemination.
The highest volume of semen had Simmental bulls (5,69 ± 0,13 ml), the
smallest volume of ejaculate characterized by semen collected from Piemontese
bulls (3,05 ± 0,07 ml). Blonde d’Aquitaine breed had the highest
concentration of spermatozoa (1545,57 ± 19,8 thous./ml). The Piemontese
semen characterised by the smallest concentration (895,56 ± 15,45 thous./ml).
Ejaculates collected in August and September had the largest volume, in January
the lowest value of this trait was recorded. The highest concentration of spermatozoa
had ejaculates collected in January. The lowest content of spermatozoa was recorded
in August and September. Seasonal variability of sperm parameters was probably
the result of a complex range of factors that can affect the animal organism,
and the crucial is the air temperature.

Key words: beef bull, ejaculate, breed, artificial insemination, sperm quality.
