| Summary: | <b>Aim: </b>In this study, it was aimed to determine the effect of parenteral vitamin
(?-carotene and vitamin E) and trace element (selenium, manganese,
copper, zinc) applications on pregnancy rates in Kangal ewes synchronized
during the breeding season.<p>
<b>Materials and Methods:</b> The presented study was carried out with 200
Kangal ewe. The animals included in the study were randomly divided into
four equal groups. Prostaglandin (PGF-2?) injections were administered
to all groups with an interval of 11 days. Before synchronization, a combination
of ?-carotene and vitamin E was applied to the one group and a
combination of trace elements (selenium, manganese, copper, zinc) to the
other group. To determine the effect of these micronutrients, both vitamin
and trace elements combinations were applied to the 4th group. In contrast,
the 1st group was accepted as the control group, and no treatment
was given. Rams were introduced to all groups 48 hours following the last
PGF-2? administration. Pregnancy diagnosis was achieved transabdominally
by ultrasonography on the 35th and 60th days after ram introduction.<p>
<b>Results:</b> Pregnancy rates of control, 2nd, 3rd, and 4th groups at the 35thday
examination were 64%, 62%, 50%, and 60%, respectively; pregnancy
rates at the 60th-day inspection were 62%, 60%, 50%, and 59%, respectively..
No statistical difference was observed between the control and other
groups. Late embryonic death and early fetal death rates were similar
between groups.<p>
<b>Conclusion:</b> It was concluded that vitamin and mineral supplementation
at the beginning of synchronization did not affect fertility, but at least 15
days ago before the onset of synchronization, repeated vitamin and trace
element supplementation may increase fertility. |
