Effects of Organic and Inorganic Forms of Manganese, Zinc, Copper, and Chromium on Bioavailability of These Minerals and Calcium in Late-Phase Laying Hens

Abstract

In the present study, the effects of dietary supplementation of organic and inorganic Mn, Zn, Cu, and Cr mixtures using two different levels (80, 60, 5, and 0.15 mg/kg and 40, 30, 2.5, and 0.07 mg/kg, respectively) on the bioavailability of these trace minerals and Ca in late-phase laying hens were evaluated. Three hundred and sixty laying hens (Barred Rock) at 50 weeks of age were used, and the duration of study was 16 weeks. Each of the four dietary regimes was randomly assigned to six replicates, which included 15 hens each. Organic trace minerals were provided as methionine chelates; inorganic Mn, Zn, and Cr were provided as oxides; and Cu was provided as sulfate. The organic form significantly increased the concentrations of serum Mn, Zn, Cu, and Ca; egg Mn, Zn, Cu, and Cr; and eggshell Zn and Cr compared with the inorganic form. However, the form of trace minerals did not affect the concentrations of serum Cr and eggshell Mn, Cu, and Ca. High-level addition of trace minerals significantly increased serum Mn and Zn; egg Mn, Zn, Cu, and Cr; and eggshell Mn, Zn, and Cu concentrations compared with low-level addition but did not affect serum Cu, Cr, and Ca or eggshell Cr and Ca concentrations. While the organic form reduced the excretion of Mn, Zn, Cu, Cr, and Ca, the high-level supplement increased Mn, Zn, and Cu excretion. The addition level did not affect Cr and Ca excretion. These results demonstrate that dietary supplementation of an organic Mn, Zn, Cu, and Cr mixture increases the bioavailability of Mn, Zn, Cu, Cr, and Ca compared with inorganic sources and that a lower level of trace mineral supplementation results in lower mineral excretion, particularly in an organic form.

Effect of Dietary Replacement of Inorganic Zinc by Organic or Nanoparticles Sources on Growth Performance, Immune Response and Intestinal Histopathology of Broiler Chicken

“…Similarly, plasma total protein was increased with Zn dietary supplementation in broiler (Feng et al, 2010). Higher calcium and phosphorus levels in broiler blood serum fed on organic or nano zinc are in agreement with those obtained by Yenice et al (2015) indicated that using the organic form of the trace mineral mixture significantly increased the serum Ca concentration compared with the inorganic form. However, Güçlü and İşcan (2004) reported that organic Mn and Zn supplementation of laying hen diets did not affect serum Ca, P, and Mg concentrations.…”

Effects of different methionine sources on production and reproduction performance, egg quality and serum biochemical indices of broiler breeders

“…Data obtained from our study showed that MHA-Ca supplementation significantly improved the eggshell thickness, relative eggshell weight and eggshell strength with. The reason may because Ca is the first restrictive factor in eggshell formation [18], and the main source of Ca in eggshell are obtained from intestinal absorption and bone Ca mobilization [19]. Thus, the explanation why MHA-Ca promoted the eggshell quality significantly may because MHA-Ca provided extra Ca source.…”

Effects of zinc sources and levels on zinc bioavailability, blood parameters, and nutrient balance of male mink (Neovison vison)

“…The fact that organic zinc source, such as ZnGly, had a significantly higher bioavailability than zinc sulfate has been reported by others (Cao et al 2000;Rider et al 2010). Yenice et al (2015) have shown that organic Zn increases the bioavailability of Zn compared with inorganic sources. Although the exact mechanism for the increased bioavailability of ZnPOS was unclear and still needs further study, several hypotheses have been proposed for the higher bioavailability of organic minerals than inorganic minerals.…”
