Effect of Birth Type on Placental Characteristics in Morkaraman Sheep

Öz

The placenta plays a central role in regulating fetal growth and neonatal performance by mediating nutrient and oxygen transfer between the dam and the fetus. In sheep, birth type is a major determinant of placental development and efficiency. This study aimed to evaluate the effect of birth type (single vs. and twin) on placental characteristics in Morkaraman sheep. A total of 24 Morkaraman ewes managed under uniform conditions were included, of which 12 delivered single lambs and 12 delivered twin lambs. Placental area (PA), placental weight (PW), and placental efficiency (PE) (birth weight/placental weight; BW/PW) were recorded immediately after parturition. Twin pregnancies were associated with significantly greater placental area and placental weight compared to single pregnancies (P<0.001). Moreover, placental efficiency was higher in twin births, indicating enhanced functional adaptation of the placenta in response to increased fetal demand. These findings demonstrate that birth type markedly influences placental morphology and efficiency in Morkaraman sheep and underscore the capacity of the placenta to adapt to multiple pregnancies under extensive management conditions.
