Abstract

Biotehnologija rasplođivanja je naziv koji objedinjuje metode koje koriste žive organizme kako
bi napravili, modificirali i poboljšali proizvod. U kontroliranim uvjetima se rasplođuju životinje
i tako se kontrolira genetska selekcija prema željenim svojstvima proizvodnje. Metode kao
umjetno osjemenjivanje, smrzavanje sperme i zametaka, sinkronizacija estrusa, multipla
ovulacija i embriotransfer (MOET), aspiraciju jajne stanice (OPU- ovum pick-up), oplodnja in
vitro, seksiranje sperme se konstantno koriste u uzgoju u cijelom svijetu jer omogućuju kontrolu
prijenosa bolesti, smanjuju troškove proizvodnje i transporta, skraćuju generacijski interval,
omogućuju razmnožavanje i dobivanje grla sa elitnim genetskim svojstvima te su brze i
efikasne. Još jedna od mogućnosti je i trgovina genetskim materijalom te pristupačnost ponude
visokokvalitetne sperme i zametaka u zemljama u kojima nije moguće dovesti stoku. Ove
metode imaju velik potencijal u očuvanju zaštićenih i ugroženih vrsta zbog kulturne baštine i
zbog ekonomskih razloga. U Hrvatskoj se ove metode koriste jako dugo te je pionir u njihovom
korištenju Laboratorij za asistiranu reprodukciju na Klinici za porodništvo i reprodukciju na
Veterinarskom fakultetu Sveučilišta u Zagrebu.

Abstract (english)

Reproductive biotechnology is a name that brings together methods that use living organisms
to make, modify and improve a product. Animals are bred under controlled conditions of
selection and thus genetic selection is controlled according to the desired production
characteristics. Methods such as artificial insemination, freezing of sperm and embryos,
synchronization of estrus, multiple ovulation and embryo transfer (MOET), ovum pick-up
(OPU), in vitro fertilization, sperm sexing are constantly used in breeding all over the world
because they enable control disease transmission, reduce production and transportation costs,
shorten the generation interval, enable breeding and obtaining cattle with elite genetic
properties, and are faster and more efficient. Another possibility is the trade in genetic material
and the availability of high-quality sperm and embryos in countries where it is not possible to
bring livestock. These methods have great potential in the preservation of protected and
endangered species for cultural heritage and economic reasons. In Croatia, these methods have
been used for a very long time, and the Laboratory for assisted reproduction at the Reproduction
and obstetrics clinic at the Faculty of Veterinary Medicine of the University of Zagreb is a
pioneer in their use.
