Abstract:

Purpose: This study is aimed at determining the effects of parenteral vitamin (-carotene and vitamin E) and/or trace elements (selenium, manganese, baker, zinc) on pregnancy rates on Kangal breed sheep synchronized during the breeding season. Tools and Methods: The presented study was carried out with 200 Kangal races of sheep. The animals included in the study were randomly divided into 4 equal groups. Prostaglandin (PGF2) between 11 days to all the groups in the study? The injection was made. The control group (1). Double dose of PGF2? There was no use other than the injection. The first PGF2 in the second group? With the injection, carotene and vitamin E; the third group was injected with a trace element (selenium, manganese, copper, zinc). The fourth group was applied a combination of both vitamins and trace elements to determine how these microbes work together. The latest PGF2 for all the animals involved in the study? 48 hours after the application, the coaching was added. In the 35th and 60th days after the coaching, an ultrasound pregnancy examination was performed by the transabdominal method. Results: The pregnancy rates in the 35th day examination of the 2nd, 3rd and 4th groups were 64, 62, 50 and 60 percent respectively; the pregnancy rates in the 60th day examination were 62, 60, 50 and 59 percent respectively. There were no statistical differences compared to the rates of pregnancy achieved in groups. There is no significant statistical difference in late embryonic death rates and early fetal death rates. It was found that vitamin and mineral supplements at the beginning of synchronization did not affect fertility, but at least 15 days before the beginning of synchronization or repeated vitamin and trace elements supplements could increase fertility.
