The meaning of Muzzle in the Bible
(From Easton's Bible Dictionary)

Grain in the East is usually thrashed by the sheaves being spread out on a floor, over which oxen and cattle are driven to and fro, till the grain is trodden out. Moses ordained that the ox was not to be muzzled while thrashing. It was to be allowed to eat both the grain and the straw (Deuteronomy 25:4). (See AGRICULTURE .)
