Turkey has a local breed goat population of
approximately 6.5 million, with low production
capacity. The indigenous goats are well known for
their tolerance to the environment but they generally
exhibit low reproductive performance. Saanen goats
are one of the best known dairy goat breeds and
have been used with success to increase milk yields
of the indigenous breeds of goats, especially where
adequate year-round feeding is assured. They were
introduced into Turkey in 1974 in order to upgrade
the local breeds (1).
Both primiparous and multiparous goats are
used in artificial insemination (AI) programs, but
fertility in primiparous females has been found to
be lower compared to multiparous females (2). For
this reason breeders prefer to use natural mating in
primiparous animals. The simplest technique for AI
in small ruminants consists of depositing the semen
at the entrance of or within the cervix, or by the
insemination pistol through the cervix, depositing the
semen directly into the uterus, which is sometimes
impossible (especially in young animals), due to the
size and structure of the cervix. Cervical insemination
offers a faster and more practical option; however,
when frozen semen is used, lower conception rates
are generally encountered. Superior and more
consistent pregnancy rates may be accomplished
when inseminating laparoscopically. The advantage
of laparoscopic insemination is that the semen is
deposited closer to the site of fertilization (2-5).
