“…In our laboratory, the multiple linear regression slope ratio method has been successfully used for estimating Fe, Mn, and Zn bioavailabilities of Fe, Mn, and Zn sources for broilers under conventional corn-soybean meal diets (Li et al, 2015;Suo et al, 2015;Zhang et al, 2016). Similarly, it is reported in other studies that Se-enriched yeast were more efficient in maintaining the GSH-Px activity level than SSe (Payne and Southern, 2005).…”

“…The bioavailability of trace minerals is defined as the degree to which an ingested element in a particular source is absorbed, transported to its site of action, and converted to a physiologically active form that can be used in metabolism by the animals (Ammerman et al, 1995;Li et al, 2015). Therefore, the sensitive criteria should be selected for estimating the relative bioavailability of Se in USSe.…”

The particle size of selenium (Se) sources could affect Se absorption and utilization, and thus it is hypothesized that the Se bioavailability might be higher in ultrafine sodium selenite (USSe) than in sodium selenite (SSe) for broilers because of USSe's smaller particle size. An experiment was conducted to investigate the relative bioavailability of Se as USSe relative to SSe for broiler chicks fed a conventional corn-soybean meal diet. A total of 504 one-d-old Arbor Acres commercial male broilers were randomly allotted to 1 of 7 treatments with 6 replicates per treatment in a completely randomized design involving in a 2 (Se sources) × 3 (added Se levels) factorial arrangement of treatments plus a Se-unsupplemented control diet containing 0.05 mg Se/kg by analysis for 21 d. The 2 Se sources were USSe and SSe, and the 3 added Se levels were 0.15, 0.30, or 0.45 mg Se/kg. The Se concentrations, glutathione peroxidase (GSH-Px) activities, and mRNA relative abundances in plasma, liver, or pancreas of broilers on day 14 and 21 were determined. The results showed that Se concentrations, GSH-Px activities in plasma, liver, and pancreas, and mRNA relative abundances in the liver and pancreas of broilers on day 14 and 21 increased linearly (P < 0.05) as the added Se-level increased. Furthermore, a difference (P < 0.05) between USSe and SSe was detected for GSH-Px mRNA relative abundance in the pancreas of broilers on day 14. On the basis of the slope ratios from the multiple linear regression of the pancreatic GSH-Px mRNA relative abundance of broilers at 14 d of age on daily dietary analyzed Se intake, the Se bioavailability of USSe relative to SSe (100%) was 158% (P < 0.05). The results from this study indicated that the Se from USSe was more available to broilers than the Se from SSe in enhancing the pancreatic GSH-Px mRNA expression.

“…Thus, Zn content in these tissues can accurately reflect the differences in Zn absorption and utilization from different Zn sources and levels. Plasma and pancreatic Zn concentrations increased linearly as dietary Zn concentration increased in Zn sulfate source at 6 or 14 d of age in broilers (Li et al, 2015). Tang et al (2015) found that Zn-bearing zeolite clinoptilolite supplementation to diets increased Zn accumulation in liver and tibia of birds compared with diet with Zn in broilers.…”

This study was to investigate the effect of zinc pectin oligosaccharides chelate (Zn-POS) on growth performance, serum enzyme activities, tissue zinc accumulation, metallothionein (MT) concentrations, and gene expression of zinc transporters (ZnT) in broilers. Five hundred forty 1-d-old Arbor Acres broiler chicks were randomly assigned to 5 dietary groups with 6 replicates of 18 birds per replicate. The diets were formulated with the same supplemental Zn level (80 mg/kg diet) but different amount of the Zn-POS: 0, 200, 400, 600, and 800 mg Zn-POS/kg diet. ZnSO 4 was used to adjust to the desired amount of the Zn (80 mg/kg) in the Zn-POS diets. Broilers were fed with the experimental diets for 42 d including the starter (days 1 to 21) and grower (days 22 to 42) phases. Our results showed that dietary supplementation of Zn-POS linearly and quadratically increased (P < 0.05) the average daily gain and gain-tofeed ratio during 22 to 42 d and 1 to 42 d as well as body weight on day 42, whereas reduced (P < 0.05) the sum of mortality and lag abnormalities in broilers on day 42. Besides, serum alkaline phosphatase and copper-zinc superoxide dismutase activities increased (P < 0.05) linearly and quadratically in response to dietary Zn-POS supplemental level on day 42. Dietary Zn-POS supplementation increased Zn accumulation in serum (linear, P < 0.05), liver (linear, P < 0.05), and pancreas (linear and quadratic, P < 0.05). In addition, Zn-POS supplementation linearly and quadratically increased (P < 0.01, P < 0.05, respectively) MT concentrations in liver and pancreas of broilers. Pancreatic mRNA levels of MT, ZnT-1, and ZnT-2 increased (P < 0.05) linearly and quadratically, and the mRNA expression of metal response element-binding transcription factor-1 increased linearly (P < 0.05), in response to dietary Zn-POS supplementation. In conclusion, supplementation of Zn-POS in the diet increases Zn enrichment in the metabolic organs such as liver and pancreas and promotes productive performance in broilers.

The role of in ovo zinc (Zn) injection in improving the embryonic development in eggs from Zn-deficient hens, via epigenetic and antioxidant mechanisms, was examined. A completely randomized design involving a 1 (the non-injected control) + 1 (the injected control with sterilized water) + 2 (Zn source) × 2 (Zn level) factorial arrangement of treatments was used. The two injected Zn sources were inorganic Zn sulfate and organic Zn-lysine chelate with a moderate chelation strength, and the two injected Zn levels were 50 and 100 μg Zn/egg. In ovo Zn injection decreased (P < 0.05) embryonic mortality, and increased (P < 0.05) hatchability and healthy chick ratio. In ovo Zn injection increased (P < 0.05) embryonic tibia Zn content, but had no effect (P > 0.05) on copper (Cu)- and Zn-containing superoxide dismutase (CuZnSOD) activities and metallothionein IV (MT4) levels or their mRNA expression levels and malondialdehyde (MDA) levels in the embryonic liver. In ovo Zn injection had no effect (P > 0.05) on the global level of DNA methylation or DNA methylation and histone 3 lysine 9 (H3K9) acetylation levels of the MT4 promoter in the embryonic liver. However, the organic Zn had higher (P < 0.05) levels of DNA methylation and H3K9 acetylation than inorganic Zn. These data demonstrate that in ovo Zn injection improved the embryonic development, and the organic Zn was more effective than inorganic Zn in enhancing DNA methylation and H3K9 acetylation in the liver MT4 promoter, but the precise mechanisms require further investigations.
