The invention discloses a feed formula for improving weaned piglet
disease resistance and application. The feed formula comprises the following raw materials: 58 to 63 parts of corn, 16 to 24 parts of bean pulp, 2 to 5 parts of
whole milk powder, 4 to 9 parts of
fish meal, 1 to 5 parts of wheat
bran, 1 to 3 parts of glucose, 0.1 to 0.5 part of acidifying agent, 0.5 to 1.5 parts of
calcium hydrophosphate, 0.5 to 1.1 parts of stone
powder, 0.1 to 0.5 part of table salt, 0.3 to 0.7 part of L-
lysine hydrochloride, 0.2 to 0.7 part of DL-
methionine, 0.2 to 0.6 part of
threonine, 1 to 4 parts of piglet premix, 0.001 to 0.01 part of
clostridium butyricum additive and 0.001 to 0.01 part of
lactobacillus acidophilus additive, wherein the weight part ratio of
clostridium butyricum to
lactobacillus acidophilus is 1 to 1, and the viable content of the two types of freeze-dried
powder is 1*10<9>CFU / g (the concentration in a feed is 1*10<4> to 1*10<5> CFU / g). As proved by a result, the mRNA (
messenger Ribonucleic Acid) level relative expressions of NLRP3, NLRP6 and NLRP12 in
jejunum in an experimental group are improved remarkably; the villus heights of the
middle segment of the
jejunum and each intestinal segment of an
ileum are increased remarkably, and the crypt depths of a
duodenum, the
middle segment of the
jejunum and an
ileum are decreased remarkably; the IL-1 beta content of serum is decreased, and the IL-10 content of the serum is increased. In the feed for
weaned piglets, the
clostridium butyricum additive and the
lactobacillus acidophilus additive are added according to a proper proportion, so that the weaned piglet
disease resistance can be improved remarkably.
