Natural service
Natural Service

  • Pasture mating

    • Male is allowed to roam freely with the females

  • Hand mating

    • Female is brought to the male for service


Artificial insemination ai
Artificial Insemination (AI)

Semen from a male animal is manually inserted into a female animal


Embryo transfer et
Embryo Transfer (ET)

  • Breeding technique where embryos from one female are collected and transferred into the reproductive tract of the other females

  • Superovulation

    • Production of multiple eggs during a single ovulation and is induced with the FSH and prostaglandin


Embryo flushing and recovery procedure

The livestock industry
The Livestock Industry

  • Nearly three-fourths of all calves born in U.S. dairy herds are conceived through AI or ET

  • Only 5% of beef calves are produced through AI or ET

  • Most AI is done in-house with fresh semen for the swine industry

  • Until recently AI was not a viable option for sheep producers. Now a new spiral catheter is used to inseminate

  • Over 90% of commercial turkeys are produced using AI


Semen quality
Semen Quality

  • Cryopreservation

    • technique for freezing semen

  • Motility

    • sperm’s ability to move independently

  • Morphology

    • size and shape of the sperm




Expected progeny difference epd
Expected Progeny Difference (EPD)

  • Producers who understand EPDs will be able to choose genetically superior animals, which will help predict the offspring’s desired qualities

  • Used to compare individual animals to other individuals of the same breed, as well as to the breed average


Pregnancy testing methods
Pregnancy Testing Methods

  • Rectal Palpation

    • gloved hand is inserted into the rectum to palpate the uterus through the rectum wall

  • Rectal Doppler Technique

    • probe that is inserted into the rectum and measures the heartbeat of the fetus or fetuses
