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.
