I took this photo to show the mineral stone for the buffaloes. They love licking the stone. Before, I had no mineral stone as the buffaloes were grazing in fields. I used to take my buffaloes to stream banks around 100 metres from my house for grazing for about an hour every day. For the past 10 years, all of the buffaloes have been confined to stalls because there is not enough grass and feed in the forest. The mineral stones are used by confined cattle as a mineral supplement. They were distributed by Li-chăn animal health officers to several households in the village.
