| Abstract | ||
| This work aims to define the effects of different seasons of the year and ages on the testicular measurements and sperm characteristics of the male Maghrebi camels. Eighty-four (42 testes) during the breeding season and (42 testes) during non-breeding season were used. The animals were divided into first, second and third groups at <4-9, <9-14 and <14-19 years of age, respectively. The obtained results revealed that testes weight (gm), testicular volume (cm3) and scrotal circumference (cm) were significantly (P<0.05) higher at <9-14 or <14-19 than <4-9 years of age either the breeding or non-breeding seasons. However, testes tone firmer score and seminal hydrogen-ion concentration (pH) value at <4-9, <9-14 and <14-19 years of age were insignificant, during the breeding or non-breeding seasons, respectively. Semen color was Creamy white, Creamy white and Milky white during the breeding season and Greyish white, Light milky white and Watery white during non-breeding season in both at <4-9, <9-14 and <14-19 years of age, respectively. The percentage of motile spermatozoa and sperm-cell concentration (×106/ml) showed significantly (P<0.05) higher values during the breeding season than non-breeding season at <4-9, <9-14 and <14-19 years of age, respectively. While the percentages of dead spermatozoa, abnormal spermatozoa, acrosome damage and chromatin damage of spermatozoa were significantly (P<0.05) higher at <14-19 or <9-14 years than <4-9 years whether in the breeding or non-breeding season. | ||
