“…Absence of any significant response in tibia parameters to Zn and Mn supplementation in excess of NRC recommendations was in agreement with the findings of Collins and Moran [9]. Published data from our previous study also showed that incremental increase of Zn from 0 to 160 ppm in diets did not alter tibia weight and percent tibia ash [5].…”

“…Often, higher levels of Zn and Mn are supplemented in diets for enhancing immune response in chicken because both minerals are responsible for sustained activity of superoxide dismutase that is vital for macrophage and heterophil integrity [8]. However, fortification of diets with excess minerals may cause antagonism affecting mineral bioavailability and masking the advantages of supplementation [9]. Our earlier study showed that Ca, P, and Zn retention in bone was negatively affected by Mn supplementation above 800 ppm level, confirming the phenomenon of antagonism with other minerals [10].…”

The purpose of this study was to investigate the interaction and main effects of supplemental Zn and Mn levels on growth, tissue mineral uptake, and immune response in broiler chicken. A basal diet of corn-soybean meal was supplemented with Zn at 40, 80, or 160 ppm and Mn at 60, 120, or 240 ppm in a factorial pattern to constitute nine experimental diets. Each diet was offered to nine replicates of six chicks in stainless steel battery brooders. At 35 days of age, body weight gain, feed conversion efficiency, hock joint scores, tibia weight, tibia strength, and percent ash were not influenced by Zn and Mn levels and their interactions. The concentration of Zn (207-238 ppm) and Mn (11.8-16.3 ppm) in tibia increased linearly with progressive raise of mineral inclusion in diets. Mn at 240 ppm level caused higher retention of Zn in tibia, but not vice versa. Manganese either alone or in combination with Zn (Zn160/Mn120 ppm) significantly reduced Cu retention (10.1-7.2 ppm) in tibia. Even in the hepatic tissue, Zn (93.6-98.4 ppm) and Mn (9.3-10.2 ppm) concentration increased linearly with their levels of inclusion in diets. When Zn and Mn levels were maintained at 4:3 ratio (80:60 or 160:120 ppm), the concentration of Zn (100-106 ppm) in liver was higher, while that of Mn was significantly more with low level of Zn (40 ppm) in diet. However, Mn supplementation at 120 ppm level and above significantly decreased Cu accumulation (19.5-17.1 ppm) in liver, but Mn × Zn interaction had no effect on Cu retention. The immune response measured as antibody titers to sheep RBC increased (5.9-7.9 log(2)) significantly with higher Zn (80 ppm) supplementation and cell-mediated immune response to phytohemagglutinin (0.57-0.78) with Mn level at 120 ppm. In summary, Zn (40 ppm) and Mn (60 ppm) as recommended by NRC was sufficient for broiler performance and bone parameters. Mn complimented Zn retention in tibia and antagonized Cu in tibia and liver tissues. Higher levels of Zn (80 ppm) and Mn (120 ppm) than those recommended by NRC were needed for improved immune response in broilers at 35 days of age.

“…However, we found that ZnCP inclusion enhanced Fe content in blood in the present study and high Fe content in the blood may result from the partial availability of Fe in ZnCP as indicated in Table , which may be due to the Zn binding process that may change the biochemical properties of Fe in ZnCP. Inclusion of diets with excess minerals could lead to antagonism, decreasing mineral bioavailability and therefore masking the true advantages of supplementation (Collins & Moran ). High Zn inclusion level in broiler diets, more than 80 mg/kg, decreased Cu accumulation in the liver (Gonzalez et al .…”

A study was conducted to investigate effects of zinc-bearing zeolite clinoptilolite (ZnCP), as an alternative for zinc sulfate (ZnSO4), on laying performance, tissue Zn accumulation and Zn transporter genes expression in laying hens. Hy-Line Brown laying hens were allocated to three treatments, each of which had six replicates with 15 hens per replicate, receiving basal diet supplemented with ZnSO4 (control, 80 mg Zn/kg diet), 0.23% ZnCP (40.25 mg Zn/kg diet) and 0.46% ZnCP (80.50 mg Zn/kg diet) for 8 weeks, respectively. Compared with control, hens fed diet containing 0.23% ZnCP had similar Zn content in measured tissues (P > 0.05). A higher ZnCP inclusion (0.46%) enhanced Zn accumulation in liver (P < 0.05) and pancreas (P < 0.05). In addition, ZnCP inclusion increased blood iron (Fe) content (P < 0.05). ZnCP supplementation enhanced jejunal metallothionein-4 (MT-4) messenger RNA (mRNA) abundance (P < 0.05). ZnCP inclusion at a higher level (0.46%) increased mRNA expression of MT-4 in pancreas (P < 0.05) and zinc transporter-1 (ZnT-1) in jejunum (P < 0.05). The highest ZnT-2 mRNA abundance in jejunum was found in hens fed 0.23% ZnCP inclusion diet (P < 0.05). The results indicated that ZnCP reached a higher bioavailability as compared with ZnSO4 as evidenced by enhanced tissue Zn accumulation and Zn transporter genes expression.

“…According to Liu et al [ 16 ], one possible reason for the reduction in Cu content in the tibia and liver and in immunity is that excessive Mn in the diet causes a disturbance in the proportions of trace elements in lymphoid organs of broiler chickens. A study by Collins and Moran [ 17 ] also confirms that a high level of Mn supplementing the diet affects the bioavailability of other minerals, masking the benefits of their supplementation. Excess Mn may disturb the balance of trace elements in the immune organs.…”

The effect of manganese nanoparticles on apoptosis and on redox and immune status in the tissues of young turkeys

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.
