Hippo+

Many English words use hippo+ as a prefix to indicate a word has  something to do with  horse or the eque+ as in equestrian.

Modern Chinese and other languages generally use compounds with MA but there's also this less common word.

a note on the two variants given for the MIN dialects. 

I have access to one online lexicon that favours Taiwanese MIN usage and I also own an old reference book, a kind of mini dictionary of Hokkien Amoy as used in the Straits area. Pinyin Qi 2 equals WG ch'i2.
