The Effect of Insemination Time, Season and Insemination Method on Calf Gender in Holstein Cattle

Abstract

The aim of this article is to determine the effect of insemination time, season and insemination method on calf gender in cattle. In the study, 792 records of inseminations and calving data between 2010-2019 were evaluated. The onset of estrus was determined based on mounting behavior. Inseminations were carried out between 0-6, 6-12, 12-18 hours after the onset of estrus. At the same time, inseminations were evaluated according to the seasons. Of the inseminations, 582 were artificial insemination and 210 were natural insemination. While insemination time and insemination method had no effect on calf gender, seasonal effect was found to be significant.
