Drought: feed for horses

hi there . thanks for taking time to read. I live in williston in the northern cape (south africa). This is a really difficult time because of the drought and food for the livestock is really scarce and expensive . i offered to help a friend and take in his horse/s . he cannot take care of them anymore and needs to focus on his farm and livestock. I have a horse and have been working with them since i can remeber. I really want to give them a home where they dont have to worry about being hungry. Because the feed is really expensive, i am open to any donation for them . one simple donation is all it takes to change an animals life. Thank you in advance and thanks for reading
