“…The power step control regulated the maximum voltage to the probe in seven increments (power steps) ranging from 10 to 40 v. Within each power step, a bull was stimulated by turning the stimulator knob smoothly from zero to the maximum voltage, then back to zero, over a period of 2-3 s. The voltage was then increased to the next higher power step and the process repeated. Once ejaculation had begun, no further increase in voltage was used unless it was judged necessary to obtain a complete ejaculate (Ali et al 2014;Tharwat, Ali, et al 2014).…”

“…Electroejaculation (EEJ) is used frequently to collect semen from infertile dromedary camels (Skidmore et al 2013;Ali et al 2014;Tharwat, Ali, et al 2014). However, the procedure has raised concerns and implications in the area of animal welfare; it is painful and stressful (Palmer 2005;Damian and Ungerfeld 2011;Fumagalli et al 2012;Whitlock et al 2012).…”

This study was carried out to evaluate the effect of electroejaculation (EEJ) on the serum concentrations of the acute phase proteins (APPs) serum amyloid A (SAA) and haptoglobin (Hp), and on the bone metabolism biomarkers osteocalcin (OC), bone-specific alkaline phosphatase (b-ALP) and pyridinoline cross-links (PYD). Twenty sexually mature apparently healthy male camels were assigned to EEJ. Parallel, 8 naturally mated male camels were enrolled as a control group. Three blood samples were collected from each camel: just before (T0), directly after (T1) and 24 h after (T2) EEJ or natural mating camels. The serum concentrations of the APPs and bone biomarkers were determined. The serum concentrations of SAA increased significantly at T1 compared to T0. In none of the 2 groups was the serum concentration of Hp differed significantly. The serum concentrations of OC increased significantly at T1 compared to T0. In none of the 2 groups was the serum concentration of b-ALP differed significantly among T0, T1 and T2. It is concluded that acute phase reaction, manifested by significant increases of SAA, had occurred in male camels as a result of EEJ. In addition, EEJ increased serum concentration of the bone formation biomarker OC.

“…The ejaculates were assessed for volume, sperm concentration, individual motility, viability, and morphology after mechanical liquefaction (Ali et al 2014). The ejaculate was liquefied mechanically by alternately aspirating and expelling it through a sterile glass pipette.…”

“…Male infertility includes lack of libido, inability to copulate, and inability to procreate (Ali et al 2014). Infections of the genital tract in male camels may lead to temporary or permanent infertility (Al-Qarawi 2005;Tibary et al 2006).…”

“…Unfortunately, research regarding infectious causes of infertility in male dromedaries is extremely limited. Chlamydia abortus (C. abortus) is a common etiological factor of reproductive failure in female dromedary camels (Ali et al 2012(Ali et al , 2014. In llamas and alpacas, chlamydiosis has been diagnosed as one of the major causes of abortion (Tibary et al 2001).…”

Potential pathogens in infertile male dromedary camels and their association with the spermiogram and clinical findings

et al. 2017

The role of five pathogens potentially implicated in the reproductive failure of 141 male dromedary camels was investigated. Breeding soundness examinations, which included semen analysis and testicular histopathology of the infertile male camels, were compared with seven camels of normal fertility. Antibodies against Chlamydia abortus (C. abortus) and Toxoplasma gondii (T. gondii) were detected using the ELISA assay. Antibodies against Trypanosoma evansi (T. evansi) were identified using the card agglutination test. The Rose Bengal plate agglutination test was used to detect Brucella species. Preputial swabs were cultured for the presence of Campylobacter fetus (C. fetus). The incidence of positive titers of C. abortus and T. evansi, and the incidence of positive culture of C. fetus was found to be 13.5, 10.6, and 7.8%, respectively. T. evansi was more prevalent in younger (5-7 years) than older (more than 7 years) camels (p = 0.02). Most of the semen characteristics were negatively affected in the camels exposed to C. abortus and T. evansi (p = 0.05). T. evansi, C. fetus, and C. abortus may have a role in lowering the reproductive efficiency of male dromedaries. However, further diagnostic techniques are recommended to confirm their association with lowered fertility in this species.
