Final answer:
Artificial insemination in horses is typically performed vaginally, using specialized tools to introduce processed semen into the mare's reproductive tract.
Step-by-step explanation:
Artificial insemination in horses is typically performed vaginally, rather than surgically or microscopically. It involves the introduction of semen into the mare's reproductive tract using specialized tools such as a pipette or a syringe. The semen is collected from a stallion and processed to remove any impurities or debris before being inseminated into the mare.
