Abstract
U radu je kod 75 krava istraživan učinak tri različita sinkronizacijska protokola. Sve krave koje su bile 45-60 dana u laktaciji pregledane su ginekološki i ultrazvučno. Shodno nalazu, podijeljene su u tri skupine: skupina A (n= 25; krave u folikularnoj fazi), tretirane su dvostrukim Ovsynch postupkom. Krave iz skupine B (n=25; krave u lutealnoj fazi), presinkronizacijskim protokolom. Treća (C) skupina (n=25 krava) tretiranih Ovsynch protokolom bez obzira na fazu ciklusa. Sve krave umjetno su osjemenjene u fiksno vrijeme. UZV detekcija steonosti realizirana je je 30. dana poslije UO. U skupini A stopa koncepcije nakon prvog umjetnog osjemenjavanja (CR1) bila je 48% (12:13), u skupini B 44% (11:14), i 28 % (7:18) u krava iz skupine C. Dvostruki Ovsynch imao je najbolji učinak dok su rezultati u krava tretiranih sa Ovsynch-om bili signifikantno lošiji. Cilj istraživanja bio je dokazati da su složeni sinkronizacijski protokoli uspješniji od jednostrukog (Ovsynch), ali i da je izuzetno važna faza ciklusa u kojoj je postupak započeo
Abstract (english)
In this work we investigated the effect of three different synchronization protocols on the 75 cows. All cows that were 45-60 days in lactation were examined and gynecological ultrasound. In accordance with the findings, cows are divided into three groups. Group A (n = 25; cows in the follicular phase), were treated with double Ovsynch procedure. Cows from group B (n = 25; cows in the luteal phase), they passed through over synchronized protocol. The third (C) group (n = 25 cows) was treated with Ovsynch protocol regardless of the phase of the cycle. All cows were artificially inseminated at fixed time. Ultrasound detection of gestation was realized 30 days after the artificial insemination. Conception rate after first artificial insemination (CR1) in group A was 48% (12:13), 44% (11:14) in group B and 28 % (7:18) in the group C. The best result was given by double Ovsynch procedure. Cows treated with single Ovsynch method gave significantly worse results. The aim of this study was to prove that complex synchronization protocols (double Osynch) perform better than single Ovsynch, also we concluded that the phase of the cycle in which procedure started is extremely important.
