| description | <b>Aim: </b>The aim of this study was to detect the effect of different
synchronization protocols on fetal sex in heifers.<p>
<b>Materials and Methods: </b>Heifers (n=120) were divided randomly
into three groups. The heifers in the first group (n=40),
the second group (40), and the third group (n=40) were
synchronized with two doses of PGF2α, Ovsynch, and intravaginal
progesterone respectively. Pregnant heifers were followed
up and the sexes of calves were recorded. Operation records of
the last year were taken in order for better evaluation.<p>
<b>Results: </b>In the first group, the pregnancy rate was 42.7% and
11 of calves born were male, 6 of them were female. In the second
group, 45% pregnancy rate was achived and 7 of calves
born of these pregnancies were male, 11 of which were female.
As for the third group, 40,0% pregnancy rate was achived and 8
of calves born of these pregnancies were male, 8 of them female.
When the operating records belongs to previous year were
analyzed, it was determined that 48,1% female calf 51,9% male
calves were born. No significant differences were found in pregnancy
rate and fetal sex rate between different groups (P>0.05).
Moreover, there was no statistical difference in gender ratio
when datas compared with operating records (P>0.05).<p>
<b>Conclusion:</b>In conclusion, it was determined that different
synchronization methods had no effect on fetal sex. Although
there was no significant differences between groups, more male
calves in PGF2α and more female calves were born in Ovsynch
group. |
