A deer gestation chart is a tool that deer farmers use to track the progress of their does during pregnancy. By monitoring the does' body weight, rumen volume, and fecal output, farmers can ensure that the animals are getting the nutrition they need and that their pregnancies are progressing normally. The chart also allows farmers to predict when does will give birth so that they can be prepared for the arrival of new fawns. Deer gestation charts are an essential tool for any deer farmer and can help to ensure a healthy and successful herd.
