“…Calving interval ranged from 20.8 to 22.1 months. This result was found to be in line with Bhakat (2000), Musa et al (2006), andGherissi et al (2020) who noted that calving interval was 22.3±3.0, 20.96, and 22.32±5.63 months, respectively. But it was found to be less than 31.2 months as estimated by Simenew et al (2013).…”

“…While it was found to be more than 4.4 years for camels in Western Sudan as estimated by Musa et al (2006). Also, Gherissi et al (2020) in Algeria noted that the average age at first calving was 4.25 years. Calving interval ranged from 20.8 to 22.1 months.…”

“…On the other hand, Simenew et al (2013) said that the number of services per conception was 1.63±0.85 in Afar camels in Ethiopia. Gherissi et al (2020) reported that the number of services per conception in Algerian camels was 2.09±1.03, and Faraz et al (2021) found that the pastoralists in Pakistan mate she-camels 2-3 times in order to get pregnant.…”

The objective of this study is to characterize the prevailing production system of raising camels in Marsa-Matrouh governorate in Egypt. A semi-structured questionnaire was designed to collect the required data randomly from 58 respondents in four regions, during the year 2020/2021. The questionnaire contains socioeconomic characteristics, herd size, management practices, milk production, reproduction performance, birth and weaning weights, and the main constraints. The obtained results showed that more than 95% of the camel's breeders were illiterate or barely read and write. Their main job is farming. Most of the breeders were landowners. The majority of the breeders are raising sheep, goats, and poultry besides camels. All camel breeders are applying natural mating. The average age of the camel at first calving was 5.5 years, and days open were 56.4 days. Calving interval ranged from 20.8 to 22.1 months. Daily milk yield was ranged from 5-10kg/head, and lactation period was around 9 months. The average birth weight for both female and male calves was 30kg and 35kg, respectively. Camel calves are weaned at about 145kg and 7 months age. The main constraints facing camel breeders were increasing feeding costs, water shortage, poor pasture, and poor veterinary care.The study concluded that camels play an important role for the people living in the harsh climate. Camel breeders are facing many problems which affect camel productivity and reflect on their economic livelihood. Proper and prompt moving is badly needed to optimize performance and achieve efficient camel production and economic return.

“…Other management flaws include breeding with a young male, overuse of males and a lack of confirmation of intromission during mating (Tibary and Anouassi, 2000). The lack of a significant strategy to improve the rational use of male camels is likely to have an impact on the fertility and productivity of Algerian camel herds (Gherissi et al., 2020).…”

The purpose of this paper was to analyse the aetiology and methods of diagnosing reproductive disorders in male dromedary camels. Male camel infertility manifests as one of three conditions: post‐coital infertility (IG), inability to copulate (IC) and lack of sexual desire (LSD). IG is mainly a testicular disorder that is linked to a deteriorated seminogram, arrested spermatogenesis, Sertoli cell‐only syndrome and testicular degeneration. For IG diagnosis, semen analysis, testicular biopsy and fine‐needle aspiration are gold standards. Testicular ultrasonography was generally inefficient. High serum FSH was found in IG camels with oligo‐ and azoospermia, implying primary spermatogenesis defects. The testis‐expressed protein (TEX101) and the epididymis‐expressed protein (ECM1) are reliable biomarkers for distinguishing between obstructive and non‐obstructive azoospermia. IC manifests in two forms: phimosis (PHI) and erectile dysfunction (ED). PHI is frequently linked to preputial and penile pathologies, as well as leucocytosis, neutrophilia and elevated nitric oxide metabolites. The majority of camels with ED have normal genital organs, and the condition is associated with an increase in cardiac troponin I. LSD is a rare disorder brought on by hormonal imbalances, high temperatures, stress and debilitating diseases. In conclusion, IG diagnosis necessitates semen analysis, testicular biopsy or fine‐needle aspiration, and FSH testing, whereas IC diagnosis requires preputial and penile examinations. Diagnostic aids include serum and seminal biomarkers.

“…She-dromedaries reach puberty at the age of 3, but typically do not reach full sexual maturity until the age of 4 or 5 [1]. The camel breeding season lasts <½ a year and coincides with the rainy season from December to May [4,5]. Ovarian follicular maturation lasts 6 days, and there is no luteal phase during the normal ovulatory cycle [1].…”

Background and Aim: Ovarian cysts (OC) in female dromedary camels have been described as problematic because they can cause infertility. This study aimed to compare the hormone concentrations and biochemical contents present in serum and follicular fluid of normal and cystic she-dromedaries of the two most common Algerian camel breeds (Sahraoui and Targui) to gain a better understanding of biological differences that may yield insights into preventing or treating this ovarian abnormality. Materials and Methods: At an abattoir in southeastern Algeria, 100 pairs of the same females' ovaries and blood samples were taken immediately after the slaughter of clinically healthy, non-pregnant females (8–15 years old) over two consecutive breeding seasons (November 2017–April 2018 and November 2018–April 2019). The concentrations of glucose, cholesterol, protein, urea, creatinine, triglyceride, gamma-glutamyl transferase, alanine aminotransferase, and aspartate aminotransferase were determined using commercial diagnostic kits and standard analytical procedures. Electrochemiluminescence immunoassay was used to measure progesterone (P4) and insulin concentrations. Results: The concentrations of glucose, insulin, cholesterol, and P4 in sera and follicular fluid (regardless of ovarian follicle diameter) were different (p < 0.001), but there was no significant difference in the other parameters studied. Glucose, insulin, cholesterol, urea, and P4 levels in blood serum differed significantly from pre-ovulatory follicles. None of the biochemical and hormonal components measured differed significantly between the pre-ovulatory and cystic fluids of the she-dromedaries studied. The breed did not affect the biochemical and hormonal composition of she-dromedary cystic and follicular fluids. Conclusion: Ovarian cysts appear to form in a metabolic milieu distinct from follicular fluid and blood serum, with no influence from camel breeds. It is suggested that further research on the blood-follicle barrier be conducted to gain a better understanding of the OC development process in she-dromedaries.
