The pasture is unlocked from the beginning of the game and does not need to be researched.
The pasture is a good building for a young village as it provides food and increases the chance to attract new inhabitants. It also doesn't require much materials and labor to build.
Since there are more buildings available to build than there is space for them, consider demolishing your Pasture in the late game, once a sufficient supply of meat is available and acquired.
