英文摘要	Aim: This study was conducted to determine the effect of seasonal variations on testosterone serum concentration, body weight, scrotal circumference, and some sperm parameters in rams living in a semi-arid region of eastern part of Algeria. Materials and Methods: Blood samples were taken monthly from eight Ouled Djellal rams, aged between 3 and 4 years, in the Technical Institute of Breeding "ITELV" located at Ain M'lila City. Sperm were collected by an electro-ejaculator once a month for 1 year (spring, summer, autumn, and winter: 3 times/season). Results: Mean values of volume, mass motility, live sperm, and scrotal circumference were higher during spring (p<0.05) with 1.23 +/- 0.26 mL, 3.39 +/- 1.07, 79.16 +/- 15.82%, and 36.29 +/- 1.91 cm, respectively; whereas, the sperm concentration was higher during autumn with 1.19 +/- 0.56x10(9) spz/ml compared to 0.46 +/- 0.13x10(9) spz/mL to spring. The season influenced significantly the percentage of abnormal sperm (p<0.05), especially during winter (6.47 +/- 2.12%), but had no influence on the weight of rams. Seasonal hormonal activity was high with 4.89 +/- 2.06 ng/mL and 3.09 +/- 1.35 ng/mL of testosterone in mating seasons (spring and autumn, respectively), knowing that the sexual season is not marked too much in these latitude. Conclusion: We can conclude that testosterone concentration is strongly correlated with the scrotal circumference and that the season has a significant influence on spermatic parameters, and that despite the large variations in sperm production, the rams can be used throughout the year.
