In order to feed your cows and sheep you need a meadow to cut the
grass and produce hay bales. Cut the grass using a mower, then you can
either load it with a loader wagon and sell it to the Biogas Plant or
continue with the steps needed to make hay bales for your animals.

Historically, I've been a fan of the Farming Simulator series on the Vita. I was surprised by how much I liked the franchise's first handheld entry, and then fully on board with Farming Simulator 14. I may not have been totally clear on what I was doing, admittedly, but I really enjoyed it nonetheless.
Farming Simulator 16 is the latest simulator by Giants Software which allows players to manage their own farm by growing and harvesting crops, raising animals, and even selling timber. Here is a walkthrough and strategy guide for the mobile version of the game.
Farming Simulator 16 returns to the Vita, and it's bigger and better than ever. A number of small tweaks and additional features makes it the best portable farming sim yet. But those improvements come with a steep price tag, and the improvements are probably not enough for an upgrade. Still, for people looking to jump in to a relaxing and long farm management game, Farming Simulator 16 is a good place to start.
