Abstract

The objective of this study was to explore the reproductive consequences of using sex-sorted semen on sex ratio, conception rate and reproductive disorders (dystocia, abortion, stillbirth) in Holstein heifers. REPRODUCTION PERFORMANCEs records which were collected during 2006 to 2013 from 4 large dairy herds in Isfahan province of Iran were used and analyzed by GENMOD procedure of SAS software. Rate of female born of SEXED SEMEN (86.3%) was 1.8 times higher than those of conventional semen (48.5%). Conception rate was generally decreased in three first services from 61.0% to 47.2% (P<0.001) in group of using SEXED SEMEN. Use of SEXED SEMEN was significantly decreased the incidence of dystocia in heifers (from 20.3% to 16.8%). There was no significant difference in abortion and stillbirth incidences between two groups of semen (P>0.05). The results of this study can used for analyses of cost- revenue for using sex-sorted semen dairy herds.
