A pygmy goat is a small breed of domestic goat. Although they produce a large amount of milk for their size, and can be eaten, pygmy goats are not typically used for milk or meat, unlike larger dairy and meat goat breeds. Pygmy goats tend to be more robust and breed more continually throughout the year than either dairy or meat goats. They have stomachs with four compartments: the rumen, the reticulum, the omasum, and the abomasum. As browsers, goats are similar to deer and enjoy variety in their diet, including woody plants.
