This study had the objective to distinguish spermatic and seminal parameters in animals born during the dry (n=11) and rainy (n=11) seasons. In the rainy season, the spermatic concentration ranging from 0.90 to 2.7 x 109/mL, the progressive motility from 16.0% to 62.0%, the mass movement from 0.3 to 2.6, vigor from 1.1 to 2.8, major sperm defects of 18.3% to 3 % and minor sperm defects from 16.1% to 3.4% . In the dry season, the spermatic concentration varied from 0.96 to 2.15 x 109/mL, the progressive motility from 35.4% to 64.1%, the mass movement form 1.7 to 3.1, vigor from 2.0 to 3.0, major sperm defects from 16.9% to 4.2% and minor sperm defects from 17.5% to 3.2%. It was observed positive correlation between spermatic motility versus spermatic mass movement, spermatic motility versus spermatic vigor as well as a negative correlation between motility versus major sperm defects of the spermatozoa and between motility and spermatozoa smaller defects respectively, in the rainy and dry seasons. Based on these results we conclude that Boer male goats born in dry season have sexual retardation of three months in comparison to those born in the rainy station. Key words: Birth season, boer, goat, puberty, sperm morphology.Downloads
