How many people have ever been involved with or been around animals? Farm
animals? Anyone ever raised an animal for breeding, or raised an animal period? Anyone
who owns or cares for any kind of male used solely for breeding knows the pains that are
associated with them. Feeding, vaccinations, fence repair, headaches upon headaches
upon headaches! Well there’s a solution to all those problems, Artificial Insemination!
What Is AI?
•General definition-the introduction of semen into the oviduct or uterus by some means
other than sexual intercourse.
• Ag definition- the use of semen from a genetically superior male to inseminate a female
resulting in a genetically superior offspring.
Where Is AI Used?
Why Use AI?
•AI provides the producer an opportunity to use sires possessing superior genetics.
Depending upon the needs and goals of an individual's breeding program, AI offers an
economically feasible means of increasing productivity over a wide range of traits.
•In spite of this enormous potential to improve production levels, many producers have
not put themselves in a position to take advantage of the benefits offered by AI.
•Best possible sires of proven quality
• Disease control
•No bull, stallion, ram, boar, etc.
–Careful herd observation required
•3-4 observations per day
–15-20 minutes per observation
–Cattle, Horses, Swine, Sheep
•“Milking of Semen”
•Collected, evaluated, cooled slowly, & frozen
•Lasts several months
•Swelling and redness of vulva
–Best indicator of estrus
–12 hours after heat detection
–3rd, 5th, & 7th day of estrus Horses
–24 and 12 hours after onset of estrus in sows
–12 and 24 hours after onset of estrus in gilts
–Two inseminations increase conception and multiple lambs
(Cattle, Horses, Swine)
•Remove all feces from the rectum
•Grasp the cervix through the wall of the rectum
–Not done with horses or swine
•Insert inseminating tube through vagina and into the cervix
•Guide tube through cervix
•Deposit semen from middle of cervix to body of uterus
Lapriscopic Artificial Insemination
•Semen injected from a syringe through a pipette into upper one-third of uterine horn
through abdominal wall
•February 19,20, & 21
