“…And the feed conversion ratio of experimental group II was reduced signi cantly as compared to the control group (P < 0.01). However, Ribeiro et al (2014) showed that feeding with B. subitils can increase the egg production rate by 2.63%, but there was no signi cant change in the feed conversion ratio [42]. In our study, the supplementation of B. velezensis could increase the average daily feed intake of experimental group I and reduce the feed conversion ratio of experimental group II.…”

Background The excessive use of antibiotics in the livestock feed industry caused inevitable side effects of microbial resistance. Besides this residual antibiotics in animal-derived foodstuff imposed serious health problems for humans. So this study aimed to investigate the potential use of Bacillus velezensis to substitute antibiotics for poultry production. A total of 468, 49-week-old Hy-Line Brown chickens, were randomly divided into four groups; the control group (regular diet), experiment group I (0.1% B. veleznesis), experiment group II (0.2% B. veleznesis), and antibiotic group (50 mg/kg flavomycin), with three replicates per group and trial period consisted on 42 days. Results The results showed that, compared with the control group, the average egg production rate and daily feed intake of experimental groups I and II increased significantly (P < 0.05), while the average egg weight was increased in experimental group II as compared to I. (P < 0.01). The feed conversion ratio was decreased (P > 0.05) in group II. Egg quality parameters such as yolk weight of the experimental group II was increased, but that of the antibiotic group and experiment group I was decreased, neither significant (P > 0.05). Moreover, the eggshell strength, yolk color, albumen height, and Haugh unit were significantly increased (P<0.05). Compared with the control group, probiotic groups can increase the progesterone and motilin (P > 0.05) but decrease the secretin and cholecystokinin in the blood plasma (P > 0.05). Conclusions This study suggested that B. velezensis can substitute in-feed-antibiotics and improved most of the study parameters significantly. Which suggested that B. velezensis has potential future application value to replace the feed antibiotics.

“…Jeong and Kim () reported that supplementation with 300 and 600 mg/kg B. subtilis C‐3102 could improve growth performance, nutrient digestibility and noxious gas emission in broilers. Ribeiro et al () reported that dietary BS at level of 8 × 10 5 cfu/g could significantly improve the egg weight and egg mass of Hyland brown laying hens. The higher egg weight was observed in the BS‐2 and BS‐3 groups than that of the control group in this study.…”

To investigate the supplemental effects of Bacillus subtilis C‐3102 on the production, hatching performance, egg quality, serum antioxidant capacity and immune response of laying breeders, a total of 480 Xuefeng black‐bone (25‐week‐old) hens were randomly assigned into four treatment groups: Hens fed the basal diets with 0 (CON), 3.0 × 105 (BS‐1), 6.0 × 105 cfu/g (BS‐2) and 9.0 × 105 (BS‐3) cfu/g of B. subtilis C‐3102. As the B. subtilis C‐3102 level increased, egg weight (linear, p < 0.01; quadratic, p = 0.003), fertility (linear, p = 0.021; quadratic, p = 0.059), hatchability (linear, p = 0.038; quadratic, p = 0.119) and yolk colour (linear, p = 0.006; quadratic, p = 0.021) increased in a linear or quadratic manner. Yolk index increased quadratically (linear, p = 0.054; quadratic, p = 0.017), and eggshell thickness (linear, p = 0.036; quadratic, p = 0.128), the activity of GSH‐Px (linear, p = 0.024; quadratic, p = 0.078), the concentration of IgM (linear, p = 0.016; quadratic, p = 0.056) and the level of AIV‐Ab (linear, p = 0.034; quadratic, p = 0.103) in the serum increased linearly as dietary supplementation of B. subtilis C‐3102 increased. The results showed that dietary treatments did not affect egg production, feed conversion ratio, egg mass, hatchability of fertile eggs, eggshell‐breaking strength, egg‐shape index, yolk percentage, Haugh unit, T‐SOD, T‐AOC, MDA, IgA and IgG concentrations and the level of NDV‐Ab in the serum. In conclusion, dietary supplementation of 9.0 × 105 cfu/g B. subtilis C‐3102 in laying breeders diets may be a feasible means of effectively increasing egg weight, fertility and hatchability, and improving egg quality such as eggshell thickness, yolk index and yolk colour. Besides, B. subtilis C‐3102 can enhance the activity of GSH‐Px, the concentration of IgM and the level of AIV‐Ab in the serum.

“…These results mean that the treatment of PSB alone or combined with B. subtilis has little effect on those indicators mentioned above. In a similar study, Ribeiro et al (2014) investigated the effects of basal diet supplemented with B. subtilis on egg quality. Their findings suggested that B. subtilis had little effect on eggshell thickness, yolk or albumen weight.…”

“…Bacillus subtilis is a non-pathogenic gram-positive bacterium, it can secrete varieties of digestive enzymes (such as protease, amylase, lipase) and these enzymes enhanced digestination and nutrients' absorption (Sonenshein et al 2000;Kodama et al 2007;Liu et al 2014). It is well known for its positive effects, such as enhancing immune function of the body (Lee et al 2014), promoting growth (Hooge et al 2004), increasing egg-laying rate (Xu et al 2006;Ribeiro et al 2014), improving egg quality (Mohan et al 1995;Abdelqader et al 2013) and adjusting microflora balance of intestinal (Lee et al 2014).…”

We investigated the effects of water supplemented with Bacillus subtilis and photosynthetic bacteria (PSB) on egg production, egg quality, serum immunoglobulins and digestive enzyme activities of Jinyun ducks. A total of 400 healthy Jinyun ducks (all aged 58 weeks) were randomly allotted to 5 treatments, with 4 replicates per treatment and 20 ducks in each replicate. The ducks were fed a standard diet for 15 days and the experimental diet for 54 days. Experimental design is as follows: negative-control group C1 was given no supplementation, control group C2 was given pool water (PW) with added PSB but not B. subtilis. Test groups T1, T2 and T3 were given the same amount of PSB in the PW and varying levels of B. subtilis in drinking water. Results suggest that PSB combined with B. subtilis had beneficial effects on the laying rate, feed-to-egg ratio, serum IgG, egg quality, especially in albumen height and Haugh unit. Additionally, PSB alone can increase the yolk-to-egg ratio, albumen height and Haugh unit.
