“…6). Our results confirm the findings of Hooge et al (15), who carried out research on broiler chickens fed with fodder with the addition of a probiotic preparation including Bacillus subtilis and the findings of Zaghari et al (39), who fed broiler chickens on a basal diet plus 0.5 (g/kg) diet B. licheniformis preparation (1 × 10 9 CFU/g). These showed greater weight gain and a lower feed conversion rate throughout the rearing period.…”

The withdrawal of antibiotic growth stimulators as of 1 January 2006 in the European Union countries has forced the search for alternative solutions to improve the health and productivity of poultry. The poultry industry also faces the challenge of developing alternative feeding systems with the restriction or exclusion of coccidiostats. One of them is the use of probiotic strains as feed additives. This study aimed to determine the effect of the use in compound feed of a probiotic containing Bacillus licheniformis on rearing rates and postmortem performance of broiler chickens. The experiment was performed on 8012 unsexed broiler chickens of the Ross 308 line divided into four equal groups. The experimental factors were the addition of a probiotic containing Bacillus licheniformis bacteria and the addition of a coccidiostat. The introduction of probiotic bacteria into compound feed did not increase the body weight of birds, in particular, control weights, and at the end of rearing, but it decreased the feed conversion rate (FCR) and mortality. Addition of probiotic in compound feed did not have a significant effect on bird muscle. The mean weight of pectoral muscle between control (C+, C–) and study (C–BL, C+C–BL) groups did not show statistically significant differences; however, the highest mean weight of the evaluated parameter was visible in the C+ group (0. 665) and the lowest in the C–BL group (0. 623). Similarly to the mean weight of the carcass, also in the mean weight of thigh muscles, the lowest statistically significant values were observed in chickens belonging to the C+C–BL group (vs. C–; P <0.05). Based on the obtained results, it can be acknowledged that the probiotic bacteria Bacillus licheniformis in broiler feed can be a good feed additive to replace antibiotics/coccidiostats. This probiotic has a positive effect on the overall health of birds, contributes to better use of nutrients and stimulates growth and development of broiler chickens.

“…A comparative study showed that B. licheniformis and B. subtilis , both as probiotics, improved BWG, FCR, and production efficiency factor (PEF). However, the former species outperformed the later in improving BWG and PEF [ 67 ]. On the contrary, studies [ 13 , 36 , 47 ] showed no effect of probiotics supplementation on broiler growth performance.…”

“…The probiotic supplementation of broilers with B. licheniformis and B. subtilis did not show a significant effect on the ileal and cecal microflora [ 67 ]. This non-significant effect on total aerobic and Salmonella count in the gut was also found when a mash diet supplemented with Lactobacillus acidophilus , L. casei , Enterococcus faecium , and Bifidobacterium thermophilus was fed to Ross 308 broiler chickens [ 93 ].…”

Probiotics are live microorganisms which, when administered in adequate amounts, confer health benefits to the host. The use of probiotics in poultry has increased steadily over the years due to higher demand for antibiotic-free poultry. The objective of this systematic review is to present and evaluate the effects of probiotics on the nutrient utilization, growth and laying performance, gut histomorphology, immunity, and gut microbiota of poultry. An electronic search was conducted using relevant keywords to include papers pertinent to the topic. Seventeen commonly used probiotic species were critically assessed for their roles in the performance and gut health of poultry under existing commercial production conditions. The results showed that probiotic supplementation could have the following effects: (1) modification of the intestinal microbiota, (2) stimulation of the immune system, (3) reduction in inflammatory reactions, (4) prevention of pathogen colonization, (5) enhancement of growth performance, (6) alteration of the ileal digestibility and total tract apparent digestibility coefficient, and (7) decrease in ammonia and urea excretion. Thus, probiotics can serve as a potential alternative to antibiotic growth promoters in poultry production. However, factors such as the intestinal health condition of birds, the probiotic inclusion level; and the incubation conditions, feedstuff, and water quality offered to birds may affect the outcome. This systematic review provides a summary of the use of probiotics in poultry production, as well as the potential role of probiotics in the nutrient utilization, growth and laying performance, and gut health of poultry.

“…It has been observed that many probiotic bacteria show a greater capacity to adhere to the chicken's intestinal mucosa than do pathogens and, therefore, displace them (Collado et al 2005). It has also been demonstrated that many probiotics favour the survival of beneficial bacteria such as Lactobacilli because they decrease intestinal pH (Olnood et al 2015a;Shini et al 2020b;Zaghari et al 2020). Lactic acid production is increased by B. amyloliquefaciens, which most probably explains the drop in ileum pH (Wu et al 2011;Salim et al 2013;Shini et al 2020b) associated with feeding this probiotic species.…”

“…New England pioneered the application of 'competitive exclusion' (Lloyd et al 1977;Soerjadi et al 1978) in Australia. Since then, many investigators have shown that probiotics can restore the composition of the gut microbiome, and introduce beneficial functions to microbial communities, and in doing so, they prevent or reduce gut inflammation and intestinal infection and improve bird performance (Eckert et al 2010;Mountzouris et al 2010;Cengiz et al 2015;Huff et al 2015;Latorre et al 2015;Park and Kim 2015;Forte et al 2016;Bai et al 2017;Pereira et al 2019;Yadav and Jha 2019;Shini et al 2020b;Zaghari et al 2020).…”

The use of probiotics in poultry production has increased rapidly, and this movement has been promoted by global events, such as the prohibition or decline in the use of antibiotic growth promotants in poultry feeds. There has been a persistent search for alternative feed additives, and probiotics have shown that they can restore the composition of the gut microbiota, and produce health benefits to the host, including improvements in performance. Probiotics have shown potential to increase productivity in poultry, especially in flocks challenged by stressors. However, the outcomes of probiotic use have not always been consistent. There is an increasing demand for well defined products that can be applied strategically, and currently, probiotic research is focusing on delineating their mechanisms of action in the gut that contribute to an improved efficacy. In particular, mechanisms involved in the maintenance and protection of intestinal barrier integrity and the role of the gut microbiota are being extensively investigated. It has been shown that probiotics modulate intestinal immune pathways both directly and through interactions with the gut microbiota. These interactions are key to maintaining gut homeostasis and function, and improving feed efficiency. Research has demonstrated that probiotics execute their effects through multiple mechanisms. The present review describes recent advances in probiotic use in poultry. It focuses on the current understanding of gut homeostasis and gut health in chickens, and how it can be assessed and improved through supplementation of poultry diets with probiotics in poultry diets. In particular, cellular and molecular mechanisms involved in the maintenance and protection of gut barrier structure and function are described. It also highlights important factors that influence probiotic efficacy and bird performance.
