This lesson takes students through the delivery process of a
calf and the potential problems along the way. During this lesson
students are given a "mission" to determine the gestation lengths
of various livestock species. After they complete the mission I
share with them a veterinarian scenario of a calf delivery, we then
discuss the stages of natural delivery including hormonal changes
that take place, and the three stages of calving. The lesson then
moves into several common delivery problems such as a large calf,
hip-lock, backwards calf, twisted uterus. We then progress into
care of a newborn calf, and students have the opportunity to
demonstrate the correct placement of obstetrical chains on a
calf.
