“…The reason for this observation may be owing to the relatively lower tissue turnover rate of the feather than the breast and liver. Our previous experiments also reported the greater responsiveness of the feather to other dietary trace minerals such as Pb and Hg than the breast and liver ( Kim et al., 2019 , 2020 ), which suggests that the feather can serve as the potential tissue of broiler chickens for accessing the effects of varying levels of dietary heavy metals with respect to their body retention ( Kim et al., 2019 , 2020 ). Moreover, the feather can be easily and continuously sampled without the sacrifice of chickens, and thus, the concentrations of heavy metals in the feather may be used to investigate the status of heavy metals in other tissues of broiler chickens.…”

“…Furthermore, it was difficult to determine better fit the data for either linear or quadratic regressions when 2 regressions were significant with high R 2 values and had similar visual closeness. Based on simplicity and adoptability, however, it may be inferred that the linear equation is more suitable compared with the quadratic equation ( Dilger and Adeola, 2006 ; Kim et al., 2019 ). On the other hand, only linear regressions for predicting daily Se intake and Se concentrations in the breast from Se concentrations in the feather were significant with high R 2 values (R 2 = 0.945 and 0.984, respectively) although quadratic regressions for daily Se intake and Se concentrations in the breast showed higher R 2 values than linear regressions.…”

“…The feather can be a good indicator of heavy metal and trace element concentrations in the body ( Couloigner et al., 2015 ; Kim et al., 2019 , 2020 ). Moreover, the feather of broiler chickens is continuously and simply collected in an animal-friendly method without the requirement for euthanizing birds.…”

The present experiment aimed to compare toxic effects of dietary organic or inorganic selenium ( Se ) and to predict of Se intake and tissue Se concentrations in broiler chickens based on feather Se concentrations. A total of four hundred twenty 7-day-old Ross 308 male broiler chicks were allotted to 1 of 7 dietary treatments in a completely randomized design. Each treatment had 6 replicates with 10 birds per replicate. Organic Se (selenium yeast) or inorganic Se (sodium selenite) was added to the basal diet at the levels of 5, 10, or 15 mg/kg Se. All experimental diets were fed to birds on an ad libitum basis for 28 d. Results indicated that a significant interaction ( P < 0.01) was observed between Se sources and inclusion levels for the BW gain and feed intake of broiler chickens with inorganic Se at 15 mg/kg in diets showing a greatest negative effect. Increasing inclusion levels of Se in diets increased (linear, P < 0.01) plasma concentrations of uric acid. Increasing inclusion levels of Se in diets increased (linear, P < 0.01) relative liver weight. No significant interactions were observed between Se sources and inclusion levels in diets on hepatic antioxidant capacity. Increasing inclusion levels of Se in diets increased (linear, P < 0.01) Se concentrations in the liver, breast, and feather. The concentrations of Se in the breast, liver, and feather were greater ( P < 0.05) for organic Se than for inorganic Se in diets. The toxic levels of organic or inorganic Se in broiler diets were near 7 or 9 mg/kg based on the BW gain, respectively. The prediction equations indicate that feather Se concentrations in broiler chickens can be used to predict both daily Se intake and Se concentrations in the liver and breast.

“…The results on the concentration of Cu and Mn in our study were similar to the study conducted in Korea [ 49 , 51 ] and, at the same time, were significantly lower than the study conducted in Belgium [ 52 ]. The received data on the content of Pb and Cd in laying hens bred in the biogeochemical province of the South Urals (Russia) were significantly lower than those observed in South Korea [ 49 , 53 ], Pakistan [ 50 ], Belgium [ 52 ],China [ 54 ], the Republic of Kosovo [ 55 ], and and were practically similar to the results obtained for Nigeria [ 56 ], as concentrations were lower than the data obtained for Belgium [ 57 ] and Malaysia [ 48 ].…”

Age features and reference intervals for the concentrations of some essential and toxic elements in laying hens

Background and Aim: Micronutrient imbalances pose a severe threat to the health and productivity of livestock and poultry. In this regard, a further stage in feeding science development will control and optimize the intake of mineral substances, including determining the elemental composition in some biosubstrates. One of these biosubstrates can be a feather. However, the amount of available information on the content of trace elements in laying hens is limited, complicating the laboratory data interpretation. Therefore, this study established reference intervals for the concentrations of the main essential and toxic elements in laying hens in different periods of ontogenesis. Materials and Methods: The study was conducted on clinically healthy Hisex Brown laying hens at the age of 10 (n=150), 30 (n=150), 120 (n=150), 150 (n=150), and 210 (n=150) days. All examined birds were born and raised on the territory of the South Ural biogeochemical province of Russia. The sampling of feathers was carried out by plucking the flight feathers of the wing. Inductively coupled plasma dynamic reaction cell mass spectrometry determined the elemental composition of the feather according to 25 parameters. Results: The results showed that at the minimum age (10 days), the highest concentrations of chemical elements were observed in laying hens. Subsequently, as they grew older, in the period from the 30th to the 120th day, there was a significant decrease in these indicators. Later, from the 120th to the 150th day, a statistically significant increase in concentrations was replaced. Little growth and relative concentration stability were observed in the last part of the experiment (150-210 days). Chemical element concentrations in feathers were computed in reference ranges for each age group. Conclusion: The calculated ranges of chemical element concentrations in laying hens can be used to compile norms for their content in the body; however, it is worth noting that these ranges can vary depending on the biogeochemical province of breeding and the bird's age.

“…One of the most popular poisonous elements in aquatic ecosystems is mercury (Hg 2+ ) in a way that even a low amount of this element can significantly affect human health [1][2][3][4][5][6][7][8]. This is due to the Hg 2+ accumulation in the human body from the food chain which causes serious damages to the brain, lungs, central nervous system, kidney, and the development of the fetus [9][10][11][12][13][14].…”

A sensitive optical sensor for determining Hg 2+ concentration has been prepared by incorporating the indicator dye, diphenylcarbazone compound, into cellulose acetate polymer film. To prepare the sensor, a cellulose acetate film was hydrolyzed with base and then the diphenylcarbazone compound bonded to the film. This method is easy to perform and uses acetyl cellulose as a carrier. According to the results, the prepared sensor was able to determine the Hg 2+ concentration with a ±6% error. Also, the adsorption capacity was 3.41 × 10 -3 mmol/g.
