Introduction
Artificial insemination (AI) = collecting semen from a male and placing it into the female reproductive tract using equipment.
- Offspring are as normal as natural mating.
- Main goal: produce many offspring from superior males.
- Semen can be used from males located far away.
- Avoids keeping expensive males on every farm.
🔹 Healthy sperm + right timing = pregnancy
- 1784 – Lazzaro Spallanzani (Italy) performed first AI in dogs.
- Proved that sperm (not seminal fluid) are essential for fertilization.
- His work became the foundation of modern AI.
🔹 First scientific proof: fertility lies in sperm cells.
4 main steps:
- Semen collection – from high-quality male.
- Evaluation – check quality, motility.
- Processing & preservation – diluted, cooled or frozen.
- Insemination – placed into female reproductive tract at optimal time.
🔹 Enables use of semen long after the male is gone.
Cost-effective – no need to keep males.
Disease control – reduces infection spread.
Quality assurance – semen tested before use.
Long-term use – even after male's death.
Easy transport – over long distances.
Safety – prevents mating injuries.
Efficiency – higher fertilization rate.
Record keeping – better breeding records.
Skilled personnel & special equipment needed.
Time-consuming compared to natural mating.
Infection risk if equipment not sterile.
