Embodiment 1

[0075] Add Lactobacillus casei PLBS004 of the present invention in the basal diet of weaned piglets, and the addition amount is 550 mg / kg.

[0076] After the breeding was completed, it was measured that the average daily gain of the weaned piglets was 452.36g, the average daily feed intake was 760.68g, the feed-to-weight ratio was 1.68, and the diarrhea rate was 0.21%. The glutathione peroxide in the serum of the weaned piglets was measured The enzyme content was 1278.1 mol / L, the superoxide dismutase content was 143.1 U / ml, the catalase content was 15.6 U / g Hb, and the malondialdehyde content was 1.5 nmol / ml.

Embodiment 2

[0078] Add Lactobacillus casei PLBS004 of the present invention in the basal diet of weaned piglets, and the addition amount is 640 mg / kg.

[0079] After the breeding was completed, the average daily gain of the weaned piglets was measured to be 448.94g, the average daily feed intake was 762.70g, the ratio of feed to weight was 1.7, and the diarrhea rate was 0.17%; The enzyme content was 1296.8 mol / L, the superoxide dismutase content was 154.0 U / ml, the catalase content was 16.9 U / g Hb, and the malondialdehyde content was 1.6 nmol / ml.

Embodiment 3

[0081] Add Lactobacillus casei PLBS004 of the present invention in the basal diet of weaned piglets, and the addition amount is 780mg / kg.

[0082] After the breeding was completed, it was measured that the average daily gain of the weaned piglets was 450.83g, the average daily feed intake was 771.58g, the ratio of feed to weight was 1.71, and the diarrhea rate was 0.19%; the glutathione peroxide in the serum of the weaned piglets was measured The enzyme content was 1308.1 mol / L, the superoxide dismutase content was 148.5 U / ml, the catalase content was 16.2 U / g Hb, and the malondialdehyde content was 1.5 nmol / ml.

[0083] Since the implementation processes of each embodiment are the same, the specific processes of other embodiments are not listed, and only the above three embodiments with better effects are listed.

Abstract

The invention is applicable to the technical field of microbial breeding, and provides lactobacillus casei. The lactobacillus casei is lactobacillus casei PLBS004, and is preserved in china general microbiological culture collection center on December 17, 2018, and the preservation number is CGMCC NO.16944. The invention further provides application of the lactobacillus casei in weaned piglet feed. The lactobacillus casei PLBS004 can improve the antioxidant enzyme activity of animal bodies, reduce weaning oxidative stress and reduce the diarrhea rate and death rate of weaned piglets, so that the production performance and economic benefits of the weaned piglets are improved.

Description

technical field [0001] The invention relates to the technical field of microbial breeding, in particular to a lactobacillus casei and its application in feed for weaned piglets. Background technique [0002] After weaning, piglets are prone to oxidative stress due to changes in diet, environment, and psychology, which can lead to growth stagnation and diarrhea, which seriously endanger the health of piglets. Although antibiotics can effectively alleviate the diarrhea caused by weaning stress in piglets and improve the growth performance of piglets, due to the increasing attention of the society to the problem of antibiotic resistance and antibiotic residues in recent years, it is necessary to find suitable antibiotic substitutes for the development of animal husbandry. Problems to be solved. [0003] Lactic acid bacteria fermented feed will not only produce a large number of metabolites such as lactic acid bacteria, organic acids, and enzymes, but also degrade anti-nutritio...
