The invention belongs to the technical field of
animal nutrition and feed formulas, and particularly relates to
antibiotics-free fermented feed for Hainan black pigs and a method for preparing the
antibiotics-free fermented feed. The
antibiotics-free fermented feed for the Hainan black pigs comprises, by weight, 35-73% of corn, 4-25% of bean pulp, 0.5-6% of
fish meal, 4-20% of rice
bran meal, 5-15% of coconut
meal, 4-12% of
bran, 0.5-1.6% of stone
powder, 0.8-1.5% of
calcium hydrogen phosphate, 0.2-0.5% of table salt, 0.1-1.0% of premixes and 0.01-0.5% of
enzyme preparations. The method for preparing the antibiotics-free fermented feed for the Hainan black pigs includes smashing and treating the corn, the bean pulp, the
fish meal, the rice
bran meal, the coconut meal, the bran, the stone
powder and the like; matching the corn, the bean pulp, the
fish meal, the rice bran meal, the coconut meal, the bran, the stone
powder and the like with the
calcium hydrogen phosphate, the table salt, the premixes and the
enzyme preparations to obtain basic
fermentation substrates; adding complex microbial preparations into the basic
fermentation substrates and carrying out sufficient
fermentation treatment to obtain the antibiotics-free fermented feed with comprehensive and balanced
nutrition. The antibiotics-free fermented feed and the method have the advantages that 4-50% of antibiotics-free fermented feed is added into conventional compound feed for black pigs at different phases, accordingly, the breeding costs of the Hainan black pig can be reduced, the feed intake and the growth speeds can be increased, the health of gastrointestinal tracts of sow and piglets can be improved, and the productivity of the Hainan black pigs can be enhanced.
