Abstract

Cilj ovog istraživanja bio je utvrditi učinkovitost CIDR-spirala u sinkronizaciji estrusa i liječenju neplodnosti kod krava. U tu svrhu slučajnim odabirom uzeti su podatci od 30-krava s 15 različitih farmi Varaždinske i Bjelovarsko-bilogorske županije. Podatci koji su prepisani s kartona su matični broj krave, pasmina, starost životinje, datum zadnjeg poroda, datum umetanja CIDR-a, da li je prije aplikacije imala cistu na jajniku te dali je nakon primjene CIDR-a i umjetnog osjemenjivanja krava ostala gravidna ili ne.
Gravidno je nakon aplikacije CIDR-a i umjetnog osjemenjivanja ostalo 60 % krava, što je zadovoljavajući rezultat. Veći uspjeh koncepcije zabilježen je kod krava holstein-frizijske pasmine, jer se kod njih CIDR umetak više koristio kao metoda sinkronizacije estrusa.
Postotak gravidnih krava je bio veći kada je CIDR vaginalni implantat bio korišten u svrhu sinkronizacije estrusa, dok je kod liječenja cista na jajnicima postotak gravidnih krava bio manji.
Kada su krave grupirane prema vremenu aplikacije CIDR vaginalnog implantata od poroda u 3 grupe, postotak gravidnosti u sve tri grupe se nije statistički značajno razlikovao .

Abstract (english)

The aim of this study was to determine the effectiveness of the CIDR device for the purpose of estrous synchronization and treatment of infertility in cows. For this purpose, randomized selection of 30 cows from fifteen farms in Varaždin and Bjelovar-Bilogora county was taken. The data recorded on the carton were: the cattle breed, age of the animal, the date of the last parturition, the insertion date of the CIDR, whether it had cyst on the ovary before the application of CIDR and pregnancy status after CIDR treatment and artificial insemination.
After CIDR application and artificial insemination, 60% of cows remained pregnant, which is a satisfactory result. A greater success of the conception was observed in cows of Holstein-Friesian breeds, because for that breed CIDR was used mainly for the purpose of estrous synchronization.
The percentage of pregnant cows was higher when the CIDR vaginal implant was used for the estrous synchronization, while in the treatment of ovary cysts the percentage of pregnant cows was lower.
When cows were grouped in 3 groups according to the time of application of CIDR vaginal implant after parturition, the percentage of pregnancy in all three groups did not differ statistically.
