The invention belongs to the technical field of agricultural
animal husbandry application, and particularly relates to a
feed additive for reducing backfat thickness of fattening Min pigs, a preparation method and application. The
feed additive for reducing the backfat thickness of the fattening Min pigs comprises the following components in percentage by weight: 0.25 to 1.0 percent of
hyodeoxycholic acid, 21.0 to 31.7 percent of
citric acid, 0.7 to 3.2 percent of neutral
phytase, 0.1 to 1.4 percent of
astragalus membranaceus, 0.3 to 1.4 percent of
saccharin sodium salt, 1.0 to 8.2 percent of rice
hull powder and 54.0 to 64.7 percent of
zeolite powder. The preparation method of the
feed additive for reducing the backfat thickness of the fattening Min pigs comprises the following steps: crushing
hyodeoxycholic acid,
citric acid, neutral
phytase,
astragalus membranaceus,
saccharin sodium salt, rice
hull powder and
zeolite powder into 80-mesh particles; the preparation method comprises the following steps: weighing the
raw material components according to the ratio, stirring in a stainless steel mixer with the mixing uniformity of less than or equal to 5% for 5-10 minutes, and quantitatively packaging to obtain the finished product. The additive in the feed from the
late stage of Min pig fattening to slaughtering can effectively reduce the backfat thickness of sows during slaughtering, improve the expression level of related genes of
muscle fibers, and further improve the meat quality of Min pigs.
