AI to date
routinely used reproductive technology in most of the domestic species
Advantages of AI
Improvement of selection of intensity, genetic and reproductive potential based on males of high genetic valu; Prebention of venereal (ST) diseases (STDs); Reliable breeding value based on high number progeny testing
Disadvantages of AI
lots of work; inbreeding; spreading gene mutations and chromosomal defects
moral, ethical dilemmas??
Technology
estrus detection; semen collection; insemination
Estrus detection
clinical signs; biosensor approach; blood sampling; cycle
estrus = in heat
Sperm collection
collection in artificial vagina, gloved hand method, electroejaculation; check motility, concentration; freezing: semen put into ionic solution, cryoprotectants added, cooled and frozen in liquid nitrogen - 196 degrees C - Bull, ram, stallion
