“… Zeng et al (2021) found that the addition of a mixture of C. butyricum , B. subtilis and B. licheniformis to broiler diets increased the body weight and average body weight of broilers. Shehata et al (2020) added Enterococcus faecalis-1 to broiler diets and found that E. faecalis improved growth performance in broilers. The results of this trial were similar to those previously reported above.…”

In this study, Bacillus subtilis, Clostridium butyricum and Enterococcus faecalis were made into a probiotic complex (PC). The PC was supplemented in AA+ male broilers’ diets to investigate the effects of PC on broiler growth performance, carcass traits, blood indicators, harmful gas emissions in feces and microbiota. Three hundred and sixty 1-day-old AA+ male broilers with an average initial body weight (data) were randomly divided into 3 dietary treatments of 6 replicates each, with 20 birds per replicate. The control group (T0) was fed a basal diet, while the test groups (T1 and T2) were supplemented with 0.025 and 0.05% PC in the basal diet, respectively. The trail was 42 days. The results showed that the supplementation of 0.05% PC significantly (p < 0.05) improved average daily gain (ADG) and average daily feed intake (ADFI) of broilers from 22 to 42 days and 1–42 days. Compared to the control group, the breast rate was significantly higher in T2, and the thymic index was significantly higher than that in T1 treatment (p < 0.05). The addition of PC had no significant effects on antibody potency in broiler serum (p > 0.05), but significantly increased albumin and total protein content in serum (p < 0.05). The addition of PC reduced H2S and NH3 emissions in the feces; the levels of Escherichia coli and Salmonella in the feces were significantly reduced and the levels of Lactobacillus were increased. And the most significant results were achieved when PC was added at 0.05%. Correlation analysis showed a significant positive correlation (p < 0.05) between the levels of E. coli and Salmonella and the emissions of H2S and NH3. Conclusion: Dietary supplementation with a 0.05% probiotic complex could improve the growth performance of broilers and also reduced fecal H2S and NH3 emissions, as well as fecal levels of E. coli and Salmonella, and increased levels of Lactobacillus. Thus, PC made by Bacillus subtilis, Clostridium butyricum and Enterococcus faecalis is expected to be an alternative to antibiotics. And based on the results of this trial, the recommended dose for use in on-farm production was 0.05%.

“…The effectiveness of probiotics can be affected by the species of microbes, amount added, and form of additives used ( Khan et al , 2019 ; Zhang et al , 2021b ). Currently, the commonly used probiotics in poultry farming include Bifidobacteria ( El-Sharkawy et al , 2020 ), Lactobacillus ( Gilliland, 1990 ), Enterococcus faecalis ( Shehata et al , 2020 ), Bacillus licheniformis ( Zhao et al , 2020b ), Bacillus subtilis ( Memon et al , 2022 ), Streptococcus thermophilus ( Sihite and Pramono, 2022 ), and Aspergillus oryzae ( Chuang et al ., 2019 ), among others. Different types of probiotics have different regulatory effects on animal health and performance.…”

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.

“…Optimised management and avoiding immunosuppressing viral diseases by vaccination to prevent secondary E. faecalis infections is the best ‘control tool’. If applied as probiotics, E. faecalis from healthy birds may even promote growth performance and immunological status and convey beneficial modulation of the caecal microbiota in broilers (Shehata et al, 2020 ). Hence, too strict measures to decrease/limit the intestinal amount of E. faecalis may not even been desirable.…”

Enterococcus faecalis (E. faecalis) was identified among the most relevant antimicrobial‐resistant (AMR) bacteria in the EU for poultry in a previous scientific opinion. Thus, it has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9 and Article 8 for listing animal species related to the bacterium. The assessment has been performed following a methodology previously published. The outcome is the median of the probability ranges provided by the experts, which indicates whether each criterion is fulfilled (lower bound ≥ 66%) or not (upper bound ≤ 33%), or whether there is uncertainty about fulfilment. Reasoning points are reported for criteria with uncertain outcome. According to the assessment here performed, it is uncertain whether AMR E. faecalis can be considered eligible to be listed for Union intervention according to Article 5 of the AHL (33–66% probability). According to the criteria in Annex IV, for the purpose of categorisation related to the level of prevention and control as in Article 9 of the AHL, the AHAW Panel concluded that the bacterium does not meet the criteria in Sections 1, 2 and 4 (Categories A, B and D; 0–5%, 5–10% and 1–10% probability of meeting the criteria, respectively) and the AHAW Panel is uncertain whether it meets the criteria in Sections 3 and 5 (Categories C and E, 33–66% and 33–66% probability of meeting the criteria, respectively). The animal species to be listed for AMR E. faecalis according to Article 8 criteria are mostly birds of the orders Galliformes and Anseriformes, but also mammals and reptiles can serve as reservoirs.
