    1. Artificial Insemination AI Jake Hoggatt 1st Presentation 02-17-04

    3. Where Is AI Used? Cattle Horses Swine Sheep Goats Dogs Humans Turkey Chickens Rabbits Fish Fox Mink Bees

    4. 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.

    5. Advantages Best possible sires of proven quality Disease control Cost effectiveness Flexibility Safety No bull, stallion, ram, boar, etc.

    6. Disadvantages Equipment Time Careful herd observation required 3-4 observations per day 15-20 minutes per observation

    7. Steps to AI (Semen Collection) Artificial Vagina Cattle, Horses, Swine, Sheep “Milking of Semen” Poultry Abdominal Pressure Fish

    8. Steps to AI (Semen Storage) Collected, evaluated, cooled slowly, & frozen -320°F Lasts several months 30 years 40 years

    9. Steps to AI (Heat Detection) Increased activity Mounting Swelling and redness of vulva Discharge Winking Mares Standing heat Best indicator of estrus

    10. Steps to AI (Insemination) Cattle 12 hours after heat detection Horses 3rd, 5th, & 7th day of estrus Horses Swine 24 and 12 hours after onset of estrus in sows 12 and 24 hours after onset of estrus in gilts Sheep Two inseminations increase conception and multiple lambs

    11. Recto-vaginal Method (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

    12. Recto-vaginal Method

    14. Lapriscopic Artificial Insemination (Sheep) Semen injected from a syringe through a pipette into upper one-third of uterine horn through abdominal wall

    15. Lapriscopic Artificial Insemination
