The invention discloses a feed additive, a preparation method thereof and an application of the feed additive in resisting piglet diarrhea. The preparation method comprises the following steps: (1) adding glycerol monolaurate and tributyrin into a container, and performing heating until the glycerol monolaurate and tributyrin are molten; (2) adding zinc oxide and performing uniform stirring; and (3) adding silicon dioxide and performing uniform stirring. By compounding glycerol monolaurate, tributyrin and zinc oxide, a good anti-diarrhea effect can still be achieved when the usage amount is reduced by one order of magnitude compared with that of single use of glycerol monolaurate, tributyrin or zinc oxide,, and the feed additive has the advantages of low dosage and high efficiency.
