Comparative study of pregnancy rate of dairy cows inseminated with fresh or frozen-thawed semen
Popis výsledku v původním jazyce
The aim of this study was to investigate conception rates (CR) achieved with artificial insemination of Holstein cows using fresh or frozen insemination doses (ID). The synchronization protocols (Double Ovsynch, Ovsynch, ReSynch) and pedometers were used to secure proper timing of artificial inseminations (AI). Total of 3979 inseminations data were recorded. Statistical analysis was performed using the SAS 9,3 package. For the evaluation of a CR, the effects of ID type, season, year, sire breed, lactation number and oestrus detection type, were analysed. Cows inseminated with fresh ID performed higher CR (plus 4,86 percent). Best pregnancy per artificial insemination (P per AI) success was observed during the winter season (plus 11,82 percent). Parity affected P per AI with primiparous having a greater P per AI than multiparous cows. The least likelihood of pregnancy success matched up with ReSynch and the highest with Ovsynch protocol (plus 7,7 percent). In conclusion, fresh ID manifested superior C
