摘要： This study aimed to investigate the effects of L. plantarum LPJZ-658 on the production, meat quality, intestinal morphology, and cecal microbiota of broilers. White-feathered broilers (1 day old, n = 600) were randomly assigned to two groups and raised for six weeks. The individuals in the LPJZ-658 group were supplemented with 2.6 x 10(9) cfu/g LPJZ-658. The growth performance, meat quality, intestinal epithelium morphology, and cecal microbiota were observed. The results showed that the average daily gain, average daily feed intake, and feed conversion ratio of broilers in the LPJZ-658 group were significantly improved. In addition, the LPJZ-658 groups had a higher thigh muscle (TM) yield, TM color, TMpH24h, breast muscle (BM) pH(24h), and BM color(24h), while the BM cooking loss was significantly lower than the CON group. Moreover, supplementation with LPJZ-658 increased ileum and cecum length, duodenum and ileum villus height, and ileum villus height/crypt depth ratio. Furthermore, 16S rRNA sequencing revealed the dietary LPJZ-658 supplementation modulated the diversity and composition of cecal microflora. At the phylum level, the relative abundances of Proteobacteria, Actinobacteria, Verrucomicrobiota, and Acidobacteriota were significantly higher. In addition, LPJZ-658 substantially decreased the genus relative abundances of Streptococcus, Veillonella, Neisseria, and Haemophilus compared with the CON group and facilitated the growth and colonization of beneficial cecal bacteria, such as OBacteroides, Phascolarctobacterium, Bacillus, and Akkermansia. It was concluded that LPJZ-658 supplementation significantly increased growth production, improved meat quality and intestinal status, and modulated the intestinal microbiota in the broilers.
