Usually not, usually it's pronounced. There are some regions, though, where the "p" is silent (same for 'Pflanze').
For example, up here. ("Ein Pferd heißt Pferd, weil man darauf fährt." -- only works because the words are pronounced the same.)
We only say "Pferd" or "Pflanze" with /pf/ in very careful pronunciation, otherwise it's "Ferd" and "Flanze" (and "Räder = Reeder" unless we are speaking carefully, and "wech" instead of "weg", and various other small deviations from the standard).
Furthermore, the German sentence is a question, thus the translation also should be one (Is the horse tired?).
Please correct me if I am wrong. In a question sequence should be verb- subject - object??
Not a chess player, but isn't the knight in chess called "Springer" in German?
Ugh, I am NEVER going to be able to pronounce Pferd, that is the hardest word I have found so far in german.
