Overview

This osteomorphometric study examines neurocranial parameters in Iraqi sheep fetuses, suggesting breeding programs may enhance desirable traits.

Key Points

  • The study aims to define osteomorphometric parameters of the neurocranium and cranial cavity capacity in Iraqi indigenous sheep.
  • Measured skull parameters in 48 sheep fetuses at 50-155 days of gestation.
  • Used electronic Vernier and measurement tape for parameters.
  • Prepared skulls through maceration with NaOH.
  • Calculated cranial cavity capacity using mustard seeds.
  • Evaluated 32 parameters within dorsal, lateral, and ventral surfaces.
  • Significant differences in skull length and width between 7-15 weeks of pregnancy.
  • Strong positive correlation between cranial cavity capacity and all variables.
  • Width of foramen magnum increased with pregnancy progression.
  • Foramen magnum index showed variable trends across pregnancy weeks.
  • Weak correlation between orbital index and total length.
