“…It is important to note that dietary Pal-Pro has a positive effect on fertilisation rate, embryo mortality, hatchability of fertile eggs, and health hatched chocks rate. Prazdnova et al (2019) demonstrated that Bacillus subtilis increased fertilisation rate and reduced the number of embryo deaths during the first 7 days of incubation. And Mazanko et al (2018) also reported that bacillus probiotic positively affected the hatchability of laying hens and sperm production of roosters.…”

This experiment was conducted to investigate the effects of different supplementation levels of palygorskite and probiotics complex (Pal-Pro) on laying performance, hatching performance, egg quality, plasma antioxidative status, and immune response of broiler breeders. A total of 432 Xuefeng black-bone chickens (42-week-old) were randomly assigned into four treatments with six replicates of 18 hens. The broiler breeders were fed the basal diet supplemented with 0, 250, 500, and 750 mg/kg Pal-Pro for 8 weeks. The Pal-Pro supplementation linearly or quadratically increased (p < .05) laying rate, fertilisation rate, hatchability of fertile eggs, heath hatched chicks rate, eggshell thickness, yolk index, total antioxidant capacity, activities of total superoxide dismutase, catalase, glutathione peroxidase, and contents of immunoglobulins, interleukin-2, and tumour necrosis factor-a in plasma. With Pal-Pro supplementation increased, feed convention ratio during 5-8 and 1-8 week, embryo mortality, malondialdehyde linearly decreased (p < .05). This finding suggested that dietary supplementation with 750 mg/kg Pal-Pro administration could improve the antioxidative status and immunoglobulins contents in plasma of broiler breeders, which may contribute to an increase in broiler's laying rate, hatching performance, egg quality, such as eggshell thickness and yolk index. HIGHLIGHTS Dietary supplementation of Pal-Pro decreased the feed conversion ratio and embryo mortality of broiler breeders. Dietary supplementation of Pal-Pro improved the laying rate, fertility, hatchability of fertile eggs, and yolk index of broiler breeders. Dietary supplementation of Pal-Pro enhanced the antioxidant capacity and the level of immunoglobulins in the plasma.

“…B. licheniformis can alleviate heat stress-induced impairments of egg production [ 28 ]. Probiotic B. subtilis can increase laying performance via several mechanisms [ 29 , 30 , 31 ]. Besides Bacillus and Lactobacillus , many other bacteria are used in the poultry industry as probiotics, such as Clostridium butyricum , which can counteract the diverse stresses in the body and has the ability to improve laying hens’ performance and egg quality [ 32 , 33 ].…”

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.

“…There are many facts that spores of Bacillus spp. In the diet have positive effects on reproductive functions [ 49 , 50 , 51 ]. This allows us to assume that the decrease in reproductive functions in animals of different genotypes on the autoclaved diet is associated with inactivation of Bacillus spp.…”

Within barrier facilities, autoclaved diet and bedding are used for husbandry of laboratory rodents. Bacillus spp. are ubiquitous in nature and some of them are known as probiotics. Inactivation of the Bacillus spores and reduction of the diet nutritional value due to autoclavation could be especially critical for immunodeficient mice. We studied the effect of the autoclaved and non-autoclaved diets on the reproductive performance and the age of prolapse manifestation in Muc2−/− mice with impaired gut barrier function and, therefore, sensitive to change of microbiota. We found that the non-autoclaved diet led to enhancement of the fertility index of Muc2−/− and Muc2+/− female mice. The non-autoclaved diet affected the prolapse of Muc2−/− mice that occurred later in comparison with females eating the autoclaved diet. We showed that Bacillus spp. was present in the non-autoclaved diet and feces of mice on the non-autoclaved diet. Bacterial strains of the non-autoclaved diet and feces belonged to B. amyloliquefaciens, B. thuringiensis, B. subtilis, Lysinibacillus macrolides, B. cereus, and other representatives of Bacillus spp. Moreover, autoclavation of the diet affected on the percent of the blood and spleen immune cells, the bacterial composition of the intestine, and increased the level of methionine in the thigh muscle of mice. Enhanced reproductive performance and delayed prolapse manifestation in Muc2−/− mice could be due to improved digestion, as Bacillus spp. from diet and feces had enzymatic activity.
