“…The number of eggs and broken and soft-shelled eggs were recorded. The weekly total egg production and the percent of marketable eggs (normal eggs without cracks, misshapen and soft shells) [33] were calculated according to the formula: weekly egg production = total number of eggs during the week /12 birds; and the percent of marketable eggs = normal eggs/total number of eggs [34].…”

This study was to investigate the effects of Bacillus subtilis on production performance and bone pathophysiological characteristics of layers. Twenty-four 48-week-old Lohmann Pink-shell laying hens were randomly divided into two groups: a basic diet (control) and the basic diet mixed with Bacillus subtilis (0.5 g/kg) for a 60-day trial. Statistically, independent-sample t-test was used to assess the treatment differences. The results showed that Bacillus subtilis supplementation improved the percent of marketable eggs (p < 0.05) with reduced numbers of broken and soft-shelled eggs but had no effects on egg weight, height of albumen, yolk color, and Haugh unit (p > 0.05). Bacillus subtilis supplement also elevated maximum load (p = 0.06), maximum stress (p = 0.01), stiffness (p < 0.01), and Young’s modulus (p < 0.01) but suppressed maximum strain (p = 0.06) in the femur. In addition, compared with control birds, phosphorous concentration (p < 0.01) was reduced in serum at day 61 but increased in the femur (p < 0.05) in Bacillus subtilis fed birds. Bacillus subtilis fed birds also had lower magnesium concentrations in both femur (p = 0.04) and feces (p = 0.09). Furthermore, Bacillus subtilis increased plasma estrogen concentration (p = 0.01) and femur TNF receptor superfamily member 11b (OPG) expression (p < 0.05) but reduced plasma IL-1 (p < 0.01) and TNF-α (p < 0.01) concentrations. These results indicate that Bacillus subtilis could be used as a health promotor to reduce overproduction-induced inflammation and associated bone damage and to increase marketable egg production. The data provide evidence for developing a management strategy to use Bacillus subtilis as a feed additive to improve marketable egg production and health and welfare status of laying hens.

“…Moreover, levels ranging from 0.25 to 0.50% of AZM not only increased the protease activity and digestibility of protein and dry matter, but also led to greater intestinal villi height, width, and density and a higher number of Lactobacillus in tilapia ( Liu et al, 2009 ) . In broilers, the supplementation of 0.5% of AZM was shown to increase the Ca and P digestibility at 21 d ( Juzaitis-Boelter et al, 2021 ). Therefore, it is possible that this mineral combination could also affect intestinal cell development and modulate the microbiota.…”

“…Previous research has been conducted to evaluate the effects of AZM on the performance in food animal production systems ( Liu et al, 2009 , 2011 ; Tan et al, 2014 ; Musthafa et al, 2016 ; Juzaitis-Boelter et al, 2021 ), and preliminary reports suggest that AZM inclusions in laying hen diets may influence marketable egg production ( Juzaitis-Boelter et al, 2021 ) and some eggshell characteristics (unpublished data). Therefore, the objective of this study was to evaluate the effects of supplementing 0.25% of AZM in the diet on the egg production, quality, and bone health of laying hens post-molt.…”

“…AZOMITE has been used as mineral fertilizer and soil amendment in crop cultivation [ 9 , 10 ]. In poultry, it was reported that dietary AZOMITE improved broiler's growth performance [ 11 ] and enhanced the mineral utilization such as calcium and phosphorus [ 12 ]. In aquaculture, AZOMITE supplementation in diets significantly enhanced the growth performance, immune capacity, and digestive function of tilapia ( Oreochromis niloticus × O.aureus ) [ 13 ] and grass carp ( Ctenopharyngodon idella ) [ 14 ], as well as improved the disease resistance of tilapia ( Oreochromis mossambicus ) [ 15 ].…”

Citric acid is an organic acid extensively used in feed industry, and AZOMITE is a hydrated aluminosilicate compound rich in rare earth elements and trace mineral elements. This study investigated the supplemental effects of AZOMITE and citric acid individual or in combination on the growth performance, intestinal microbiota, morphology, digestive enzyme activity, serum indexes, and disease resistance of juvenile largemouth bass. Six diets were designed, including the control diet (CON) and the five additive-supplemented diets with the addition of 4 or 8 g/kg citric acid (CA4, CA8), 3 g/kg AZOMITE (A3), and their combined addition as 4 g/kg citric acid + 1.5 g/kg AZOMITE) (C4A1.5) and 8 g/kg citric acid + 3 g/kg AZOMITE (C8A3). Juvenile largemouth bass with initial body weight of 22.01 ± 0.09 g were fed the six diets for 56 days. The results revealed that the combined addition of 4 g/kg citric acid and 1.5 g/kg AZOMITE (C4A1.5) increased weight gain by 7.99% ( P < 0.05 ), and decreased feed conversion ratio by 0.07 ( P < 0.05 ). The protein retention in the C4A1.5 group and the lipid retention in all additive-supplemented groups were significantly higher than those in the control group ( P < 0.05 ). In serum, all additive-supplemented groups showed significantly higher glutathione peroxidase activity than the control group ( P < 0.05 ). The activities of superoxide dismutase and catalase in the CA8, A3, C4A1.5, and C8A3 groups were significantly higher ( P < 0.05 ), while the concentration of malondialdehyde was significantly lower than those in the control group ( P < 0.05 ). Moreover, the total antioxidant capacity in the A3 and C4A1.5 groups, and lysozyme activity in the A3, C4A1.5, and C8A3 groups were significantly increased when compared to the control group ( P < 0.05 ). In digestive enzyme, the protease activity in the A3, C4A1.5 groups, and amylase activity in the CA4, CA8, and C4A1.5 groups were significantly higher than those in the control group ( P < 0.05 ). In intestinal microbiota, Firmicutes abundance was elevated in all additive groups, while the Fusobacteriota and Plesiomonas shigelloides abundance were decreased. In the intestinal histology, the CA8, A3, and C4A1.5 groups showed significantly higher villus height than the control group ( P < 0.05 ). After the infection with Aeromonas hydrophila, the cumulative mortality of all additive-supplemented groups was significantly lower ( P < 0.05 ), and the C4A1.5 group demonstrated the lowest mortality. In conclusion, the combined supplementation of 4 g/kg citric acid + 1.5 g/kg AZOMITE increased the growth, antioxidant, immune capacity, improved the intestinal morphology and microbial flora of juvenile largemouth bass, and promoted the resistance against Aeromonas hydrophila infection.
