“…Oxidative stress happens when the excessive production of reactive oxygen species overwhelms the capacity of antioxidant systems in the body (27,28). Previous studies have shown that zinc has an antioxidant function (29), and supplementation with ZM reportedly decreases the concentration of MDA, but increases that of MT and T-AOC in the serum of ruminants (14,17,23), and similar results were also observed in the present study. Different from ZM, ZP did not present the same antioxidant effects as ZM because it did not affect the serum MT or T-AOC concentrations compared with the CON group.…”

Two experiments were conducted to identify the optimal dose of zinc proteinate (ZP) in the diet for dairy calves and then to compare early supplementation with the ZP or zinc methionine (ZM) on the growth performance, incidence of diarrhea, antioxidant status, and immune function of dairy calves during their first month of life. In Experiment 1, forty newborn female Holstein dairy calves were randomly divided into four groups (n = 10): a control group (without ZP supplementation, ZP0) or groups that received ZP supplementation at 40, 80, and 120 mg zinc/day, respectively (ZP40, ZP80, and ZP120). The experiment lasted 14 days, and the growth performance, incidence of diarrhea, and serum zinc concentration were analyzed. In Experiment 2, thirty-six newborn female Holstein dairy calves were randomly allocated to three groups (n = 12): a negative control group (without zinc supplementation, CON), a positive control group (supplemented with 80 mg zinc/day in the form of zinc methionine, ZM), and a ZP group (supplemented with 80 mg zinc/day in the form of ZP). The experiment lasted 28 days, and the growth performance, incidence of diarrhea, serum zinc concentration, serum antioxidant indicators, and concentrations of plasma immunoglobulins and cytokines were determined on days 7, 14, 21, and 28. Results showed that in Experiment 1, supplementation with ZP to yield 80 mg zinc/day increased the ADG (P < 0.01) and serum zinc concentration (P < 0.01), and decreased the F/G (P < 0.01) and the incidence of diarrhea (P < 0.05) during days 1–14. In Experiment 2, compared with the CON group, ZP increased the ADG (P < 0.01), serum zinc concentration (P < 0.01), and plasma immunoglobulin G (IgG; P < 0.01) and IgM (P < 0.01) concentrations, but reduced the incidence of diarrhea (P < 0.01), serum malondialdehyde (P < 0.01), and plasma interleukin-1β (P < 0.01) concentrations during days 1–28. Overall, ZP supplementation to yield 80 mg zinc/day improves the growth performance and immune function, and decrease the incidence of diarrhea of dairy calves, which was comparable to the same dose of zinc in the form of ZM.

“…In comparable with the recent results of Zn-Me supplementation in different species, Mostafa et al (2019) found significant increase in TP and AL in She-camel. Also, serum TP and AL concentrations showed significant increase in dairy calves (Dresler et al, 2016). Plasma TP increased with Zn dietary supplementation in broiler (Bahakaim et al, 2014).…”

Effect of dietary zinc-methionine (Zn-Me), on growth performance, carcass characteristics, anti-oxidant status, immunity, liver and kidney functions of NZW growing rabbits was studied. Total of 80 rabbits were assigned into 4 groups fed basal diet with 0 (G1), 50 (G2), 100 (G3) and 150 (G4) mg of Zn-Me/kg diet, respectively. The average of body weight, weight gain, daily feed intake and feed conversion, performance index and viability rate were recorded at age intervals from 5 to 13 wk. The carcass characteristics, hematological and biochemicals, anti-oxidant and Immunoglobulins in serum were determined at the termination of the experimental period (13 wk). Results revealed that Zn-Me (100mg/kg diet) addition increased (P<0.05) growth performance (body weight of rabbits at 9 and 13 wk of age, and daily gain of rabbits at 5~13 wk of age interval), hemoglobin, red blood cells, platelets and hematocrit, and neutrophils and eosinophils, serum total proteins, glucose, total anti-oxidant capacity, glutathione reduced ,glutathione S-transferase and superoxide dismutase, and immunoglobulins concentrations. The count of blood cells and lymphocytes, monocytes and acidophils percentages, and triglycerides, creatinine, urea concentrations, and enzyme activity and thiobarbituric acid-reactive substances concentration decreased (P<0.05) as affected by Zn-Me (100mg/kg diet). The carcass net weight, dressing percentages (based on carcass net carcass weight or plus edible organs), and spleen and heart weight percentages were (P<0.05) the highest in G3 compared with other groups. In conclusion, dietary supplementation with zinc-methionine (100 mg/kg diet) can improve growth performance, lipid profile, immunity and anti-oxidant status, without adversely effects on kidney and liver functions of growing rabbits.

“…However, some extent of dissociation and loss of organic trace minerals in the upper gastro-intestinal tract is unavoidable (Cao et al 2000). Despite these inevitable losses, organic trace mineral supplementation can benefit the nutrition of ruminants, improving their production and health (Gressley 2009;Dresler et al 2016).…”

Effects of different dietary manganese sources on thickness of mucus layer and selected biochemical and haematological indicators in sheep

et al. 2018

The effects of manganese from organic and inorganic sources supplemented to diets of sheep on intestinal mucus production and on selected biochemical and haematological indicators were investigated. The experiment was carried out on 18 sheep of the Improved Valachian breed aged seven months over the period of four months. The animals were divided into three groups of six animals each (group 1 – control, basal diet with 31 mg Mn/kg, group 2 – basal diet + manganese sulphate (MnSO4) with 120 mg Mn/kg, group 3 – basal diet + manganese chelate of glycine hydrate (Mn-Gly) with 120 mg Mn/kg). Intestinal segments (duodenum, jejunum, ileum, caecum) were collected and mucus production was assessed using the quantification method. Mucus production in the duodenum and jejunum was significantly lower (P < 0.05) in group 3 (Mn-Gly) compared to the control and group 2 (MnSO4). In the duodenum in group 2 (MnSO4) mucus production was similar to the control. Biochemical indicators were determined using spectrophotometry, and haematological indicators were measured using a haematology analyzer. Significant changes (P < 0.05) were found for the concentrations of total proteins and albumins. The concentration of total proteins was lower in group 3 (Mn-Gly) compared to the control and group 2 (MnSO4). In the latter group it was higher compared to the control. The concentration of albumins was higher in group 3 (Mn-Gly) compared to the control and group 2 (P < 0.05). The results indicate a decrease of intestinal mucus in the group supplemented by Mn-Gly chelate, which may mean a lower mucus barrier for manganese absorption.
