In this farm, pigs are automatically killed with lava, giving you roasted meat.
This farm is very suitable if you have a lot of resources in survival mode. You can also lure the animals into the cage and multiply them there with wheat. So it is easy to get a lot of food. I personally find it more profitable than a grain farm.
1) Here the pigs are flushed into the lava channel.
2) Then the pigs fall into the lava.
3) So then the pork meat goes into the hopper and then falls into the box.
4) This is the proof that it worked!
