The present invention discloses a preparation method of a feed lactic acid bacterium microcapsule. The activity of lactic acid bacteria in the prepared lactic acid bacterium microcapsule in the prior art is low, the lactic acid bacteria cannot be rapidly released in intestinal tract and cannot tolerate the high temperature in the feed pelleting process, the microcapsule is prone to absorb moisture and get deteriorate during the storage process, and the cost is relative high. The feed lactic acid bacterium microcapsule preparation method comprises the following steps: A, modifying pullulan; B, preparing capsule core material; C, preparing wall material; D, preparing capsules; E, coating lactic acid bacterium microcapsule semi-finished products; F, performing shaping and pre-drying; and G, obtaining the lactic acid bacterium microcapsule finished products. The modified water proof pullulan is used as a main component for a coating material, after coating, a water proof layer is formed on the surface of the lact
