Artificial insemination in dromedary camels

Area of Science:

• Reproductive biology
• Animal science
• Veterinary medicine

Background:

• Artificial insemination (AI) is crucial for genetic progress in domestic animals.
• AI in camelids is infrequent due to semen collection/handling difficulties and induced ovulation in females.
• Seminal plasma's gelatinous nature poses challenges for semen processing.

Purpose of the Study:

• To review camel semen collection and analysis methods.
• To evaluate liquid semen storage and insemination parameters.
• To discuss ovulation induction and insemination timing in female camels.

Main Methods:

• Semen collection using an artificial vagina.
• Semen analysis for concentration and morphology.
• Evaluation of different buffers for semen preservation (liquid and frozen).
• Assessment of insemination techniques and timing relative to ovulation induction.

Main Results:

• Artificial vagina is the optimal method for camel semen collection.
• Highest pregnancy rates achieved with 150x10^6 live spermatozoa in uterine body 24h post-GnRH induction.
• Green Buffer or lactose (11%) diluents are effective for liquid semen storage.
• Green and Clear Buffer show promise for freezing dromedary semen; pellets yield higher post-thaw motility.

Conclusions:

• Optimized AI protocols can enhance camelid reproductive efficiency.
• Further research is needed to improve fertility of frozen-thawed camel semen.
• Effective semen preservation is vital for genetic advancement and animal transport reduction.
