The application of
Lactobacillus plantarum LPJZ‑658 in improving the growth performance, meat quality and
disease resistance of broilers relates to the field of microbial agents. The
Lactobacillus plantarum LPJZ‑658 was deposited in the General
Microbiology Center of the China
Microbiological Culture Collection Administration on July 16, 2021, with a deposit number of CGMCC No. 22908. The present invention found that
Lactobacillus plantarum LPJZ‑658 can significantly increase the average daily feed intake and average daily
weight gain of broilers, significantly reduce the feed-to-weight ratio, significantly reduce the liver /
body weight ratio and intermuscular fat width, significantly increase the pH value and meat color of the
breast muscle, significantly reduce the cooking loss of the
breast muscle, significantly improve the color of the
leg muscle, significantly reduce the
malondialdehyde content in the immune hind
leg muscle, significantly increase the level of
superoxide dismutase in the immune hind
leg muscle, significantly increase the height of the duodenal and ileal villi and the ratio of the villus crypts, and significantly increase the level of IgG antibodies in the serum.
