During parturition, a breech birth describes fetal presentation. Breech birth is characterized with a calf presenting butt first with no front or hind limbs entering the birth canal. The tail and hindquarters of the calf can be palpated via the vagina.
The cause of breech birth is not known, but it does not appear to be related to cowherd nutrition or genetics.
When a breech birth is experienced, professional assistance (veterinarian) should be immediately consulted.
