| Abstract |
A total number of 65 clinically healthy male dromedary camels were used in the present study. The age of these camels ranged from 5 to 10 years and their weights were approximately 500 kg an average. The experimental work aimed to investigate the effect of breeding and non-breeding seasons either hot-humid or hot-dry months on testicular measurements, epididymal semen characteristics and histological changes in the right and left testes of the dromedary camels. The obtained results showed that, the testis weight, testicular volume, scrotal circumference, testis tone firmer score and the percentage of sperm motility, sperm-cell concentration of the dromedary camels were significantly (P<0.05) higher during breeding than non-breeding season either hot-dry or hot-humid months, while the percentages of dead spermatozoa, sperm abnormalities and acrosomal damage of spermatozoa were significantly (P <0.05) higher during hot-humid months as compared to both hot-dry months and breeding season.
Semen colour was creamish white, milky white and watery white during breeding season, hot-dry and hot-humid months, respectively. Semen consistency was viscous during breeding season and hot-dry months and semi-viscous during hot-humid months. Seminal pH value was significantly (P <0.05) higher during hot-humid months as compared to both breeding season and hot-dry months. The testis of the male dromedary camels during breeding season showed consisted of numerous semineferous tubules (ST) with different shapes and size (oval, ovaid and circular) were highly active. The ST lined by spermatogenic cells at different maturation stages (spermatogonium, spermatocytes, spermatid and spermatozoa) are present as compared to camels during non-breeding season either hot-dry or hot-humid months.
