The invention relates to a health
disease-resistant pig
feed additive comprising the following components in parts by weight: 0.2-0.5 part of
zinc lactate, 0.4-0.8 part of beta-
dextranase, 5-9 parts of isomalto-
oligosaccharide, 0.5-1 part of
yeast powder, 0.5-0.9 part of
bifidobacterium bifidum probiotics
powder, 0.5-1 part of
bacillus laterosporus powder and 9-12 parts of an attractant composition, wherein the attractant composition comprises the following components in parts by weight: 2-6 parts of
jerusalem artichoke residues, 1-3 parts of rape seeds, 1-3 parts of hawthorns and 5-8 parts of perilla seeds. The preparation method of the
feed additive comprises the following steps: weighing the components in parts by weight, screening through a 50-mesh
sieve, uniformly mixing, screening again, performing wet method
pelletizing,
drying, and screening the dried particles through a 20-mesh
sieve to obtain the additive. Compared with the prior art, the pig
feed additive provided by the invention can effectively adjust the balance of intestinal florae of animals to improve the food calling property, promote growth and development, and significantly promote the
immunity and production performance of pigs, and has a very strong health
disease-resistant effect; and moreover, a preparation process of the additive is simple, is low in cost, and can also reduce
ammonia nitrogen discharge to the environment.
