Megjegyzések:	The purpose of the present study was to test the hypothesis that season has an affect on semen quality and scrotal circumference ofDorper rams. The experiment was carried out with six Dorper rams aged between 15 and 18 month. Semen samples were collected withartificial vagina and volume, concentration (x 109/ml), total sperm number/ejaculate (x 109), mass motility (0-5), progressive motility (%), scrotalcircumference (cm) was observed. Significant differences (P<0.05) were observed in concentration, total sperm number/ejaculate, scrotalcircumference in different seasons. Volume was the highest in autumn (1.4?0.5 ml) and the lowest in the spring (1.3?0.4 ml). Concentrationof semen was lower in spring (2.6?1.5 x 109) and summer (3.3?1.5 x 109) as compared to fall (4.1?1.1 x 109) (P<0.05). Regardingtotal sperm number/ejaculate (x 109), scrotal circumference (cm) all the seasons differed significantly (P<0.05), although the season had noeffect on mass motility and progressive individual motility (P<0.05). In conclusion the present study showed that semen quality parametersand scrotal circumference of Dorper rams were better in autumn than in the other sea-sons.
