“…Bai et al [ 44 ] also found that increased addition of Mn to the diet of laying hens increases Mn-SOD activity. In a study on chickens, Bozkurt et al [ 3 ] found that increasing Mn supplementation in the diet to above the recommended level stimulates the antioxidant system and reduces lipid peroxidation mechanisms. Fouad et al [ 45 ] found no effect of increasing Mn supplementation to 90 mg/kg diet on the plasma MDA level or SOD activity in ducks.…”

“…Due to these physiological functions of Mn, poultry diets are enriched with this element, usually by adding various chemical forms of Mn, including MnO and Mn 2 O 3 [ 3 ]. It is accepted that in the case of growing turkeys, the addition of Mn to the diet should amount to 60 mg kg -1 of feed throughout the rearing period [ 4 ].…”

“…Phytase hydrolyses phytic acid to inositol and improves absorption of Mn [ 33 ]. In the last decade, researchers have been increasingly searching for alternative chemical forms of Mn, mainly organic compounds of this element [ 3 ], which are highly bioavailable and which reduce the amount of Mn released into the environment. It is also believed that the addition of smaller amounts of Mn in the form of nanoparticles to turkey diets may be a way to improve the absorption of Mn from the diet and reduce its excretion into the environment.…”

The aim of the study was to determine whether the use of Mn nanoparticles would make it possible to reduce the level of this micronutrient added to turkey diets without adversely affecting growth performance, antioxidant and immune status, or apoptosis. The experiment was conducted on 6 groups of turkeys with 10 replications in a two-factor design with 3 dosages of manganese, 100, 50 and 10 mg/kg, and 2 sources, manganese oxide (MnO) and manganese nanoparticles (NP-Mn2O3). The study showed that irrespective of the form of Mn used, reducing the Mn level recommended by British United Turkeys for supplementation of the diet of young turkeys from 100 mg/kg to 10 mg/kg increases the content of this element in the blood with no adverse effect on growth performance or the immune system. The reduction in Mn supplementation in the form of NP-Mn2O3 from 100 to 50 and even to 10 mg/kg of turkey diet has no negative effect on antioxidant defence in young turkeys. A 50% reduction of the recommended Mn level in the form of MnO enhances lipid oxidation processes. Replacing MnO with NP-Mn2O3 in the turkey diet probably can increase apoptosis in young turkeys. On the other hand, irrespective of the form of Mn used, reducing supplementation of the turkey diet with this element from 100 to 50 and even to 10 mg/kg probably can reduce apoptosis.

“…An in vitro study indicated that MnSOD activity and mRNA expression level in chick embryonic myocardial cells were improved by 1.0 mmol/L of Mn as MnCl 2 treatment [ 36 ]. Studies also have shown that dietary inclusion of Mn as MnSO 4 , Mn methionine, or Mn oxide improved MnSOD, CAT, and GSH-Px activities and T-AOC, while reducing MDA level in serum, liver, and leg muscle of broilers [ 25 , 37 ]. In this study, dietary inclusion of MHC increased MnSOD and CAT activities and T-AOC, while decreasing MDA content in serum and liver of broilers.…”

“…Studies reported that dietary supplementation of Mn as MnSO 4 , MnCO 3 , and MnO could increase the length, weight, diameter, breaking strength, and density index of tibia in broilers [ 42 , 43 , 44 ], reduce the incidence of leg abnormalities [ 25 , 32 ]. However, Bozkurt et al [ 37 ] reported that dietary supplementation of Mn as Mn-methionine and MnO with levels 12.5, 25, and 50 mg/kg has no effect on the weight, length, diameter, and density index of tibia in broilers. It is assumed that the different bioavailability of different chemical forms in Mn sources may be the reason which resulted in these inconsistent results.…”

This study was conducted to investigate the effects of dietary supplementation with manganese hydroxychloride (MHC) on production performance, antioxidant capacity, tibial quality, and manganese (Mn) deposition of broilers. A total of 756 one-day-old male Arbor Acres broilers were randomly allotted to 7 treatments of 6 replicates with 18 broilers per replicate. Broilers were fed corn-soybean meal basal diets supplemented of 100 mg/kg Mn as Mn sulfate (MnSO4), or 0, 20, 40, 60, 80, 100 mg/kg Mn as MHC for 42 days. The growth performance of broilers was not affected by dietary MnSO4 or MHC (p > 0.05), whereas the dressing percentage increased linearly (p < 0.05) with increasing of dietary MHC addition level. The activities of catalase (CAT) and manganese superoxide dismutase (MnSOD), and total antioxidant capability (T-AOC) in serum and liver on day 42 increased linearly (p < 0.05) with increasing of dietary MHC level, while malondialdehyde (MDA) concentration reduced linearly (p < 0.05). The length, strength, and density index of tibia increased linearly (p < 0.05) on day 21 as MHC supplementation level increased; there were no differences between MnSO4 group and 40–100 mg/kg Mn as MHC groups in tibial parameters of broilers (p > 0.05). As supplemental MHC levels increased, the Mn contents in heart, liver, kidney, and tibia increased linearly on day 42 (p < 0.05). In summary, dietary supplementation with MHC improved antioxidant capacity, bone quality, and Mn contents in broilers, but no effects on growth performance were detected. Based on the results of this study, dietary inclusion of 50–90 mg/kg Mn in the form of MHC to broilers is recommended.

Background It has been reported that supplementation of manganese (Mn) could alleviate the negative effects of age on egg quality in laying hens. However, limited information is available on compensatory ways in order to reduce the adverse effects of hen age on health and Mn deposition in the body. Objectives The objectives were to investigate the effect of organic and inorganic sources of Mn on antioxidant activity, immune system, liver enzymes, shell quality and Mn deposition in the tissues of older laying hens. Methods A total of 250, 80‐week‐old Leghorn laying hens (w36) were allocated into five treatment groups with five replications in a completely randomised design. Treatments were control (without Mn supplementation), 100% Mn sulphate, 75% Mn sulphate + 25% organic Mn chelate, 50% Mn sulphate + 50% organic Mn chelate and 25% Mn sulphate + 75% organic Mn chelate. Results The groups fed 50 and 75% organic Mn chelate exhibited the lowest feed conversion ratio, as well as the maximum laying percentage, and egg weight and mass. Except to those fed 75% Mn sulphate, the hens received Mn supplements either as organic or inorganic, had higher immunoglobulin G and M compared with the control ( p < 0.05). A significant elevation in the values of superoxide dismutase was observed in the hens receiving 50 and 75% organic Mn chelate when compared with the other treatments. The ALP activity decreased with increasing organic Mn chelate. Mn supplementation, either as organic or inorganic, increased Mn deposition in bone, egg yolk and shell, serum and liver. Conclusion Dietary supplementation with 50–75% Mn–methionine has the potential to replace Mn‐sulphate in laying hens’ diet for improving eggshell quality, Mn deposition in the eggshell, antioxidant capacity and immune response, as well as improving laying performance, egg weight and feed conversion ratio.
