Troughs can be used to feed livestock. Large troughs can feed pigs and sheep, small troughs only chickens. Grain can be placed in the trough by right-clicking the trough with the grain item in hand. Large troughs also accept dry grass, but larger quantities are required.
After placing down a trough, players may fill the trough with various food items by right-clicking. Small troughs only accept grain, while large troughs accept more items. Different animals will eat different food items. Troughs can hold a maximum of 8 portions of food at a time.
Small troughs take one piece of grain per trough food portion. Large troughs take 2 pieces of grain or vegetables, or 8 pieces of dry grass, per trough food portion. Therefore, fully filling a large trough takes 64 pieces of dry grass, a full stack. Troughs do not accept mixed types of food, and must be emptied out before refilling with a different type of food.
Wild animals near placed and filled troughs will naturally be attracted towards it. One method of capturing animals for domestication is to place a filled trough inside a 2-block-high pit, so that animals can fall into the pit but not jump back out.
