Introduction

  • Artificial insemination (AI) has been said to be the most important single technique devised for the genetic improvement of animals, because it allows a few select males to produce enough sperm to inseminate thousands of females per year.
  • The technique permits cooling or freezing of semen for storage and shipping to remote destinations allowing a greater geographical distribution of genetics.

Uses

Advantages

  • Allows widespread use of outstanding sires from around the world increasing genetic gain.
  • Increased utilization of the best genetics with stud bull use much greater than can be achieved in normal breeding lifetimes Genomics: overview.
  • Improved biosecurity: AI negates the risk of sexually transmitted infectious disease, eg campylobacter Campylobacter spp.
  • Allows for greater flexibility and choice in bull use, on an individual cow basis, for example, bull breed, traits etc.
  • Negates the risk of infertile ill or lame stock bulls during the breeding season.
  • Negates the risk of work, health and safety issues concerned with stock bull use.

Disadvantages

  • Requires heat detection Estrus: signs and detection by farm staff, or estrus synchronization.
  • Requires appropriately trained insemination technicians.
  • Increased pressure on technicians in terms of results achieved
  • Requires accurate record keeping.
  • Propagation of genetic defects on a large scale, eg Mulefoot, CVM.
