AB  - The objective of this paper was to compare heifers reproductive traits and characteristics of their
calves after artificial insemination performed by conventional (non-sexed) and sexed sperm on 6
commercial farms in Serbia. Conception rate was 55% and 44% for conventional and sexed semen,
an average gestation length being 274.6 and 274.9 days, respectively. Average body mass at birth
was 37.47 and 36.75 kg for non-sexed and sexed semen, respectively. The rate of stillbirths and
twinning was 6.19 and 3.78% for conventional and 7.54 and 1.13% for sexed semen, respectively.
The use of conventional semen exerted no statistically significant (P>0.05) effect on female: male
calves relationship (51.96 : 48.04) while artificial insemination by sexed semen highly significantly
(P<0.01) changed calf sex-ratio (85.10 : 14.90). First-calf heifers originating from sires whose sperm
was obtained in conventional way produced 7880 kg milk with 269 kg milk fat and 242 kg protein in
standard lactation, while first-calf heifers originating from sires whose sperm was sex-sorted
produced 8184 kg milk with 251 kg milk fat and 242.3 kg protein. Type of insemination (conventional
and sexed semen) did not significantly affect the studied milk yield traits (P>0.05).
