“…The effects of antibiotics and probiotics on the GIT microbiota in chickens were extensively studied by using metagenome sequencing (amplified libraries of 16S rDNA gene fragments were sequenced on the Illumina platform) [29,45]. It has been indicated that in the caeca of broilers, Clostridia are the predominant organisms [30], while the genus Lactobacillus is dominant in the ileum [46].…”

Probiotics can act as an alternative to antibiotics in animal feeding, but their use is minimal due to their expensive production. Dry grass is rich with bacteria beneficial for animal feeding and can be used as a probiotic. However, data about the quantitative dependence of the grass microbiome on environmental factors and seasons remain insufficient for preparing “grass-meal-based probiotics”. Four grass samples were collected in two geographically remote regions of Russia; their microbiome was characterized by metagenomic sequencing of 16S rDNA libraries and microbiological seeding, and biological testing of the grass meal was carried out on 6 groups of birds containing 20 Ross 308 cross broilers each for a period of 42 days. The positive control group (PC) obtained 16–25 mg/mL toltrazuril (coccidiostatic agent) and 0.5 mL/L liquid antibiotic enrostin (100 mg/mL ciprofloxacin and 106 MU/mL colistin sulfate in the commercial preparation) within the drinking water, while the negative control group (NC) obtained no medicines. Four experimental groups were fed the diet supplemented with 1% grass meal over the period of 7–42 days of life; no commercial medicines were used here. A spontaneous infection with Eimeria was registered in the NC control groups, which caused the loss of 7 chickens. No losses were registered in the PC group or the two experimental groups. In two other experimental groups, losses of coccidiosis amounted to 10% and 15%, respectively. All specimens of the grass meal demonstrated a significant effect on the average body weight gain compared to NC. Taken together, these observations support the hypothesis that the grass meal may substitute toltrazuril for protecting the chickens from parasitic invasion and increase average daily weight gain (ADG) as effectively as the antibiotic enrostin.

“…It was reported that bacteria such as Clostridium difficile and Lactobacillus can modulate mucin-related gene expression or mucin secretion of ( Mack et al, 1999 ; Lindén et al, 2008 ). According to the findings from former research in our laboratory ( Jia et al, 2022b ), the composition of 1 unknown species belonging to the Clostridiales genus was significantly reduced in the WB group. There is no evidence showing that this Clostridiales genus is related to mucin expression.…”

“…Although the composition of intestinal microbes at different developmental stages is tightly regulated, the developmental time and succession of intestinal microbes are affected by various factors ( Pandit et al ., 2018 ; Ngunjiri et al ., 2019 ). Studies have confirmed the influence of production management, diet, disease, genetics, and other factors on the composition of gut microbes ( Yadav and Jha, 2019 ; Popescu et al , 2021 ; Upadhaya et al , 2021 ; Jia et al , 2022 ; Liu et al , 2022a ). Importantly, there is an urgent demand for green antibiotic substitutes in the chicken industry following widespread concerns regarding antimicrobial resistance and consequent antibiotic bans.…”

Regulatory Effects of the Probiotic <i>Clostridium butyricum</i> on Gut Microbes, Intestinal Health, and Growth Performance of Chickens

Clostridium butyricum is an important probiotic for chickens and exerts various biological activities, including altering the composition of the intestinal microbiota, competing with other microorganisms for nutrients, improving the integrity of the intestinal mucosal system, changing the intestinal barrier, and improving overall host health. Intestinal microbes also play vital roles in maintaining the intestinal barrier, regulating intestinal health, and promoting chicken growth. During chicken production, chickens are vulnerable to various stressors that have detrimental effects on the intestinal barrier with significant economic consequences. C. butyricum is a known probiotic that promotes intestinal health and produces the short-chain fatty acid butyric acid, which is beneficial for the growth performance of chickens. This review elucidates the development and utilization of C. butyricum to improve intestinal barrier function and growth performance in chickens through its probiotic properties and interactions with intestinal microbes.
