General Structure

  • Usually 14 mammary complexes
  • Arranged in two rows on the ventral side of the thorax and abdomen.
    • In most animals, left and right complexes not at the same transverse plane - arranged alternating.
      • Facilitates access of piglets when the sow is lying on her side.
  • Each complex consists of two or three mammary units.
  • Each unit opens with a separate orifice at the tip of the teat in a shallow depression.



Blood Supply

  • Thoracic mammary complexes receive additional blood supply from mammary branches of the lateral thoracic artery.
