Probiotics colonize the intestine of animals and birds and provide useful effects on their performance and immune status. This study describes a high throughput screening and characterization of spore-forming bacteria from Iranian poultry farms with the aim to identify potential probiotic native Bacillus spp. and determine its effects on growth performance, hemato-biochemical parameters, immunity, intestinal microflora, morphology and MUC2 gene expression of broiler chickens. A total of 300 one-day-old female Ross 308 broilers (42.6 ± 0.6 g) were used in a 6-wk study. Broilers were randomly allotted to 1 of 3 dietary treatments consisting of 4 replicate cages with 25 broilers each: 1-Control (Corn-soy-based diet: C), 2-C + 200 g/ton of the GalliPro® (Bacillus subtilis DSM 17299, 4×10 9 CFU/g, as positive control group: PC), 3-C + 200 g/ton of the native probiotic (B. tequilensis K03, 4×10 9 CFU/g: NP) identified in this study. During the experiment parameters were measured weekly. The results revealed that birds of the NP and PC groups exhibited improved feed conversion ratio (FCR) and increased body weight (BW), carcass and breast meat yield compared with the birds of the C group (P<0.05). Also, lymphocytes level, antibody titers against Newcastle diseases virus (NDV) and infectious bronchitis virus (IBV) of vaccinated birds were increased, while serum triglycerides, total cholesterol levels and abdominal fat of birds fed NP and PC were decreased compared to birds of the C group (P<0.05). The villus height, the relative expression of MUC2 gene and Bacillus spp. populations were increased, while E. coli was significantly decreased in the ileum content of treated groups (P<0.05). These results indicate that the identified native B.tequilensis K03 strain can improve immunity and broiler performance by modifying intestinal microflora and morphology. Studied native probiotic Bacillus tequilensis K03 has useful effects on health status and it can be used as poultry feed supplement.

Bacillusprobiotics: an alternative to antibiotics for livestock production

SummaryThe use of probiotics as feed supplements in animal production has increased considerably over the last decade, particularly since the ban on antibiotic growth promoters in the livestock sector. Several Bacillus sp. are attractive for use as probiotic supplements in animal feed due to their ability to produce spores. Their heat stability and ability to survive the low pH of the gastric barrier represent an advantage over other probiotic micro-organisms. This review discusses important characteristics required for selection of Bacillus probiotic strains and summarizes the beneficial effect of Bacillus-based feed additives on animal production. Although the mechanism of action of Bacillus probiotics has not been fully elucidated, they are effective in improving the growth, survival and health status of terrestrial and aquatic livestock. Bacillus strains also have utility in bioremediation and can reduce nitrogenous waste, thereby improving environmental conditions and water quality. Finally, recent innovative approaches for using Bacillus spores in various applications are discussed.

“…Recent investigations have suggested that the gut microbiota is an important environmental factor affecting energy harvest from the diet and energy storage in mammals, and these studies have focused on the relationship between the gut microbiota and obesity [25][26][27]. Other studies of chickens have shown that the gut microbiota plays a key role in regulating fat metabolism [28,29].…”

Background A growing body of evidences suggest critical role of the chicken gut microbiota in growth performance and fat metabolism. However, the underlying mechanism by which the gut microbiota affects chicken growth performance by regulating fat metabolism remains unclear. The purpose of current study was to compare cecal microbial communities between high and low body weight chickens and verify the correlation between fat metabolism and gut microbiota. Results Seven-week-old male and female chickens with significantly different body weight were used in the present study. 16S rRNA gene sequencing was used to reveal the cecal microbial community. Fat metabolism levels were compared between high and low body weight chickens. Spearman correlation analysis was used to analyze the relationship between the cecal microbiota and fat metabolism. Transferring fecal microbiota from adult chickens with high body weight into one-day-old chickens was examined by oral administration to verify gut microbiota effects on chicken growth through regulation of fat metabolism. There were significant differences in body weight, chest and leg muscle indexes as well as in cross-sectional area of muscle cells, suggesting different growth performance between high and low body weight chickens. By comparing the relative abundance of gut microbes in the cecal content in high and low body weight chickens, we found that Microbacterium and Sphingomonas were more abundant in high body weight chickens and Slackia was more abundant in low body weight chickens. The fat metabolism level was markedly different in serum, liver, abdominal adipose, chest and leg muscles between high and low body weight chickens. Spearman correlation analysis showed a positive correlation between fat metabolism and the relative abundance of Microbacterium and Sphingomonas and a negative correlation between fat metabolism and the abundance of Slackia. Hence, transferring fecal microbiota, instead of saline, from adult chickens with high body weight into one-day-old chickens improved growth performance and fat metabolism in liver. Conclusions These results suggested that cecal microbiota could affect chicken growth performance by regulating fat metabolism.
