“…The villus length (L), villus width (W), and crypt depth of 10 intact villi were measured per slide. The villus area (S) was calculated using the following equation (Bai et al, ):

S = μ \times (\frac{W}{2}) \sqrt{{(\frac{W}{2})}^{2}} + L^{2}

Development of automatic breeding management accelerated the growth of chicks. However, health conditions of the chicks become more susceptible to external antigens. Mortality of neonates is closely related to the economic profit; thus, maintaining the fitness of young poult is the primary mission. The early growth and development of the intestine in the poults is a crucial process related to the fitness of the chicks. Gut barriers form a key line of defense against the foreign antigens of the environment and play the critical roles in maintenance of intestinal homeostasis. The primary layer of gut barriers includes an outer layer comprised of bacteria and an inner layer associated with high concentrations of sIgA and mucins (Chen, Tellez, Richards, & Escobar, 2015). Over the past few decades, the intestinal microbiota has been shown to play important roles in growth performance, immune status, and intestinal health in broiler chickens (Luan, Sun, Wang,

“…Besides, it has been proved that the small intestine is the earliest organ damaged in oxidative damage, and its integrity is very important to resist oxidative damage. Probiotics can improve the small intestinal performance by lowering the pH value, stimulating its intraepithelial lymphocytes and increasing its antioxidant capacity (Bai et al, ; Ferket, ). Dietary probiotics in diets have been shown to be beneficial in improving the adverse influence of oxidative stress, thus inhibiting the excess of ROS that may cause cell damage and finally improving the health of the host (Deng et al, ).…”

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.

“…The administration of L. salivarius or L. plantarum in feed significantly increases the levels of short-chain fatty acids and induces a healthier pattern in the intestinal microbiota of broiler chickens [ 13 , 14 ]. Dietary supplementation with B. subtilis has positive effects on productivity, the stimulation of immune activities, and the improvement of antioxidant capacity in broilers [ 15 ]. Dietary supplementation with Enterococcus faecalis strain UGRA10 increases the ileum and caecum bacterial diversity in laying hens [ 16 ].…”

We investigated the efficacy of a single bacterium strain, Bacillus subtilis (B. subtilis) YW1, on the performance, morphology, cecal microbiota, and intestinal barrier function of laying hens. A total of 216 28-week-old Hy-line Brown laying hens were divided into three dietary treatment groups, with six replicates of 12 birds each for 4 weeks. The control group (Ctr) was fed a basal diet and the treatment groups, T1 and T2, were fed a basal diet supplemented with B. subtilis at a dose rate of 5 × 108 CFU/kg and 2.5 × 109 CFU/kg, respectively. Dietary supplementation with B. subtilis did not significantly affect overall egg production in both groups, with no obvious changes in average egg weight and intestine morphology. B. subtilis administration also improved the physical barrier function of the intestine by inducing significantly greater expression levels of the tight junction protein occludin in T1 (p = 0.07) and T2 (p < 0.05). Further, supplementation with B. subtilis effectively modulated the cecal microbiota, increasing the relative level of beneficial bacteria at the genus level (e.g., Bifidobacterium p < 0.05, Lactobacillus p = 0.298, Bacillus p = 0.550) and decreasing the level of potential pathogens (e.g., Fusobacterium p < 0.05, Staphylococcus p < 0.05, Campylobacter p = 0.298). Overall, B. subtilis YW1 supplementation cannot significantly improve the egg production; however, it modulated the cecal microbiota towards a healthier pattern and promoted the mRNA expression of the tight junction protein occludin in laying hens, making B. subtilis YW1 a good probiotic candidate for application in the poultry industry, and further expanding the resources of strains of animal probiotics.
