Technical Note: Transcervical deep cornual insemination of goats

Area of Science:

• Veterinary Medicine
• Animal Reproduction
• Goat Breeding

Background:

• Traditional laparoscopic intrauterine insemination in goats can be invasive and requires specialized equipment.
• Improving artificial insemination (AI) techniques is crucial for efficient goat breeding programs.
• Frozen-thawed semen presents challenges for achieving high conception rates in goats.

Purpose of the Study:

• To describe a novel trans-cervical deep uterine insemination technique for goats.
• To compare the efficacy of the new transcervical method with laparoscopic intrauterine insemination.
• To evaluate kidding rates and litter sizes achieved with both insemination techniques.

Main Methods:

• Development of a new trans-cervical deep uterine insemination procedure for goats.
• Experimental comparison between transcervical and laparoscopic intrauterine insemination using frozen-thawed semen in estrus-synchronized Boer goats.
• Insemination of parous does transcervically without hormone treatment for further evaluation.

Main Results:

• The transcervical insemination method yielded a significantly higher kidding rate (71%) compared to laparoscopic insemination (53%) in synchronized does (P < 0.025).
• Litter sizes were also significantly larger with the transcervical method (2.27) versus laparoscopic (1.89) (P < 0.01).
• Transcervical insemination in non-synchronized parous does resulted in a 71% kidding rate and 1.76 litter size.

Conclusions:

• Trans-cervical deep uterine insemination is a viable and effective alternative to laparoscopic insemination in goats.
• The novel technique offers potential advantages in terms of efficiency and reproductive outcomes.
• Further research may explore broader applications of this method in goat artificial insemination programs.
