Artificial
Insemination in Pigs
A very cheap
and practical way to carry out genetic improvement is through
the use of artificial insemination (AI). The strength of AI is
generally dependent on the genetic superiority of the boar and
the possibility of spreading its qualities to more females to
produce offsprings of better genetic quality.
The swine AI technology includes boar selection and evaluation;
semen collection, evaluation, processing and storage; estrus detection;
procedure of insemination; and breeding performance evaluation.
By using AI, one ejaculate can be used to breed 10 sows on the
average compared to only one when natural mating is practiced.
Other advantages of AI in pigs are the following:
- minimizes
if not totally control the spread of reproductive diseases;
- allows
the use of physically handicapped or crippled, yet genetically
superior boars that cannot normally perform natural mating;
- avoids
possible injuries on either the boar or the sow/gilt that may
happen during mating;
- infertile
boars are immediately detected;
- allows
breeding of females from distant places with less transport
costs and inconvenience, and without causing travel-related
stress on the boar;
- allows
small-scale raisers to keep a few sows without maintaining a
boar;
- eliminates
the problem of mating boars and sows of different sizes;
- increases
the number of sows bred by a boar and the possibility of extending
the boars’ productive life; and
- reduces
breeding cost.
