“…This supplementation frequently oversupplies trace minerals in an attempt to avoid deficiency; however, this practice increases the excretion of minerals causing environmental contamination ( Mézes et al, 2012 ). Yang et al (2021) reported that avoidance of under- and overprovision of dietary minerals will achieve optimal growth performance and reduce mineral excretion. There is currently an imbalance between the development of poultry production and research in trace minerals, leading to a limited knowledge of trace mineral requirements ( Bao and Choct, 2009 ).…”

Abnormally low or high levels of trace elements in poultry diets may elicit health problems associated with deficiency and toxicity, and impact poultry growth. The optimal supplement pattern of trace mineral also impacts the digestion and absorption in the body. For ducks, the limited knowledge of trace element requirements puzzled duck production. Thus, the objective of this study was to investigate the influence of dietary inclusions of coated and uncoated trace minerals on duck growth performance, tissue mineral deposition, serum antioxidant status, and intestinal microbiota profile. A total of 1,080 14-day-old Cherry Valley male ducks were randomly divided into six dietary treatment groups in a 2 (uncoated or coated trace minerals) × 3 (300, 500, or 1,000 mg/kg supplementation levels) factorial design. Each treatment was replicated 12 times (15 birds per replicate). Coated trace minerals significantly improved average daily gain (p < 0.05), increased Zn, Se, and Fe content of serum, liver, and muscle, increased serum antioxidant enzyme (p < 0.05) and decreased the excreta Fe, Zn, and Cu concentrations. Inclusions of 500 mg/kg of coated trace minerals had a similar effect on serum trace minerals and tissue metal ion deposition as the 1,000 mg/kg inorganic trace minerals. Higher concentrations of Lactobacillus, Sphaerochatea, Butyricimonas, and Enterococcus were found in birds fed with coated trace minerals. In conclusion, diets supplemented with coated trace minerals could reduce the risk of environmental contamination from excreted minerals without affecting performance. Furthermore, coated trace minerals may improve the bioavailability of metal ions and the colonization of probiotic microbiota to protect microbial barriers and maintain gut health.

“…Dong et al (2022) concluded in his work that inorganic trace minerals may be effectively replaced by low levels of complex organic trace minerals in laying hens during the late production stage. Corroborating these findings, Yang et al (2021) concluded that diets supplemented with the organic trace minerals at 50% of the NRC profile in laying hens promoted optimum laying performance, mineral deposition, and reduced mineral excretion.…”

This study aimed to evaluate the responses in performance, egg quality, and health of internal organs of laying hens of Hisex White lineage. The birds were provided with diets supplemented with organic minerals (OM) + tributyrin, associated or not with a mixture of organic acids (benzoic formic, citric, and phosphoric), compared to a control treatment containing zinc bacitracin (28 ppm). In total, 160 laying hens of the commercial Hisex White lineage of 68 w and an average weight of 1.735 ± 0.025 kg were distributed in 40 experimental plots. The study employed a completely randomized design, with five treatments and eight replications/treatment. The experimental period was divided into seven production cycles of 21 days, totalling 147 experimental days. The variables analysed were egg production and loss, feed intake, mean egg weight, egg mass, feed conversion, and internal and external quality variables of eggs. At the end of the experimental period, the final weight of the birds was measured to evaluate the relative weight of liver and kidneys. No significant effect of the treatments on the productive performance and internal and external quality of the eggs was evident. The association of organic minerals with a mixture of organic acids and tributyrin did not influence the productive performance and internal and external quality of the shell of Hisex White laying hens in the period from 68 to 89 weeks of age.

“…In a 57-week-old Beijing Red Layer hens experiment, replacing 0–50% inorganic trace elements with organic compound trace elements did not affect the growth performance of layers ( 9 ). In addition, the study showed that 50% NRC ( 18 ) level of organic mineral elements supplementation to 26 weeks Roman layer diets did not influence feed intake, egg-laying rate, and feed egg ratio ( 21 ). Similarly, some studies also found that organic trace elements supplementation had no significant effect on production performance compared with inorganic trace elements ( 22 – 24 ), which is consistent with the present study.…”

This study was conducted to evaluate the effects of organic trace elements (Cu, Fe, Zn, and Mn) on performance, egg quality, trace elements utilization, and intestinal function in late-phase laying hens. A total of 1,080 laying hens (Hy-line brown, 65 weeks old) were randomly assigned to four treatments with six replications of 45 layers each. The basal diet was prepared without adding exogenous trace elements. The control group was fed with a basal diet supplemented with 600 mg/kg of inorganic trace elements. The three treatment groups were fed basal diets supplemented with 300, 450, and 600 mg/kg organic trace elements (OTE300, 450, and 600), respectively. The results showed that there was no significant difference in growth performance among all treatments. However, OTE450 significantly improved the eggshell strength of laying hens (p < 0.05), but had no significant effects on haugh unit, egg yolk weight, eggshell weight, and eggshell thickness, compared with other groups. Moreover, compared with the control group, OTE450 significantly increased the contents of copper, iron, and zinc in serum (p < 0.05). Meanwhile, all of the trace elements had a lower deposition in the feces in organic trace elements groups (p < 0.05). Histological analysis showed that the addition of organic trace elements could significantly improve the villus height and villus concealment ratio (p < 0.05). In addition, the messenger RNA (mRNA) and protein expressions of divalent metal transporter 1 (DMT1), zinc transporter 1 (ZnT-1), and ferroportin 1 (FPN1) were the highest in the OTE450 group. In conclusion, OTE450 could improve egg quality, intestinal function, and trace element utilization efficiency. Thus, this study provides a theoretical basis for the application of low levels of organic trace elements in laying hens.
