Abstract :The aim of this study was to describe seasonal changes in scrotal circumference, sperm motility, sperm concentration, percentage of abnormal spermatozoa and biochemical and enzymatic properties of seminal plasma for 9 months in 10 mature fat-tailed Akkaraman and Awassi breed rams. Scrotal circumference and semen were evaluated monthly from rams and seminal plasma separated from semen to study it. Scrotal circumference, sperm motility and sperm concentration were higher during autumn months. Furthermore, autumn months showed moderate percentage of abnormal spermatozoa. The biochemical analyses of ram seminal plasma indicated that the highest values of total protein, albumin insert ignore into journalissuearticles values(A);, globulin insert ignore into journalissuearticles values(G);, total lipid and cholesterol were recorded in autumn while A/G ratio exhibited the lowest values. Alanine amino transferase insert ignore into journalissuearticles values(ALT); showed the lowest values in summer, while aspartate amino transferase insert ignore into journalissuearticles values(AST); and AST/ALT ratio exhibited the lowest values in autumn. The results suggest that rams show seasonality for some reproductive parameters and seminal plasma constituents; therefore Akkaraman and Awassi rams could be bred successfully in autumn months.
