“…Zn being an integral component of ALP, higher bioavailability of organic source [ 33 ] might have resulted in increased ALP activity. Similarly, many workers [ 28 , 34 ] reported increase in ALP activity with Zn supplementation. Reducing Zn supplementation from 12 to 9 ppm from Zn-nic did not affect serum total protein, albumin and globulin concentration, but further reduction in Zn concentration (6 ppm) reduced globulin concentration ( Table-5 ).…”

Aim:A study was undertaken to investigate the effect of organic zinc (zinc nicotinate, Zn-nic) supplementation (6, 9, and 12 ppm) compared to inorganic zinc (12 ppm) on growth performance, hematology, serum biochemical constituents oxidative stress, and immunity in weaned female Sprague–Dawley rats.Material and Methods:A 48 weaned rats (285.20±1.95 g) were randomly distributed to 4 dietary treatments with 6 replicates in each and reared in polypropylene cages for 10 weeks. Basal diet (BD) was formulated with purified ingredients without zinc (Zn). Four dietary treatments were prepared by adding 12 ppm Zn from ZnCO3 (control) and 6, 9, and 12 ppm Zn from Zn-nic to the BD. On 42nd day, blood was collected by retro-orbital puncture for analyzing hematological constituents, glucose, cholesterol, alkaline phosphatase, total protein, albumin, and globulin and antioxidant enzyme activities. At 43rd day, rats were antigenically challenged with sheep red blood cell (RBC) to assess humoral immune response and on 70th day cell-mediated immune response.Results:Weekly body weight gains, daily feed intake, blood hematological constituents (white blood cell, RBC, hemoglobin concentration, packed cell volume, mean corpuscular volume, lymphocyte, monocyte, and granulocyte concentration) and serum glucose, total protein levels were comparable among the rats feed Zn from ZnCO3 and Zn-nic (6, 9, and 12 ppm). Serum cholesterol reduced with organic Zn supplementation at either concentration (6-12 ppm). Serum globulin concentration reduced (p<0.05) with 6 ppm Zn-nic supplementation compared to other dietary treatments. Lipid peroxidation lowered (p<0.05) reduced with 12 ppm organic Zn; thiobarbituric acid reacting substances and protein carbonyls concentrations in liver reduced (p<0.05) with 9 and 12 ppm levels of organic Zn supplementation compared to 12 ppm Zn supplementation from inorganic source. RBC catalase and glutathione peroxidase enzymes activities were highest (p<0.05) in rats supplemented with 12 ppm Zn-nic, followed by 9 ppm. Comparable immune response (humoral and cell-mediated) was observed between 12 ppm inorganic Zn and 9 ppm organic Zn and higher (p<0.05) immune response was noticed at 12 ppm Zn-nic supplementation.Conclusion:Based on the results, it is concluded that dietary Zn concentration can be reduced by 50% (6 ppm) as Zn nicotinate without affecting growth performance, hemato-biochemical constituents, antioxidant status, and immunity. In addition, replacement of 12 ppm inorganic Zn with 12 ppm organic Zn significantly improved antioxidant status and immune response.

“…Results obtained herein are in agreement with Fawzy, El‐Sadawi, El‐Dien, and Mohamed () who stated that dietary zinc decreased triglyceride concentration. On the other hand, Al‐Daraji and Amen () reported that the addition of Zn to diets of broiler breeder chickens at 50, 75 and 100 mg/kg resulted in significant increase in plasma total cholesterol. On the contrary, Lu and Combs () found that supplementation of zinc did not affect serum cholesterol level in chickens.…”

This study was conducted to evaluate the effects of zinc methionine (Zn-Met) supplementation on the performance, egg quality, antioxidant status and some biochemical parameters of blood serum in laying hens from 22 to 34 weeks of age. A total of 120 Hisex Brown laying hens of 22-week-old were randomly allocated into five treatments with six cage replicates for each (four hens/replicate). Dietary treatments consisted of the basal diet with no Zn-Met supplementation (control group) and basal diet supplemented with 25, 50, 75 or 100 mg Zn-Met/kg diet. No significant differences were observed on body weight, body weight gain or feed conversion ratio due to dietary Zn-Met supplementation. However, highly significant impact was observed on daily feed intake. Egg number, egg weight and egg mass were increased in the group fed diet supplemented with the highest level of Zn-Met (100 mg/kg of diet) as compared to other groups. All egg quality traits were statistically (p > .05 or .01) affected as a response to dietary Zn-Met supplementation except egg shape index, shell percentage and yolk index. In comparison with the control group, dietary supplementation of 25, 50, 75 or 100 mg Zn-Met/kg decreased serum triglyceride and LDL-cholesterol levels. Serum cholesterol level was increased with all dietary levels of Zn-Met in comparison with the control group. Dietary Zn-Met supplementation increased the serum content of zinc, where the highest values were recorded with 50 and 100 mg Zn-Met/kg diet. Dietary Zn-Met levels did not affect the antioxidant indices in blood serum except for the activity of copper-zinc superoxide dismutase (Cu-Zn-SOD). The activity of Cu-Zn-SOD was increased with Zn-Met supplementations with no differences among supplemental zinc levels. It is concluded that dietary Zn-Met supplementation reduced serum triglyceride, LDL-cholesterol and increased Zn status and resulted in promoting antioxidant ability of laying hens, and the addition of 100 mg Zn-Met/kg to layer diet was appropriate for improving the above parameters in addition to egg production indices and Haugh unit score.

“…Supplementation of nano-Zn to broiler diets (0.06 mg/kg) accompanied by decreasing the blood cholesterol level and improving the bird's immunity when compared with organic and inorganic Zn sources [17]. The alteration of blood cholesterol levels may be linked to the zinc's role in enzymes systems (metalloenzymes) which plays a vital role in fat metaboilsm [53]. Ahmadi et al [50] reported that the dietary nano-ZnO had no significant role in aspartate amino transferase and alanine amino transferase activities in serum of broilers.…”

Different sources of Zinc (Zn) were compared to assess their possible effects on performance, nutrients retention, mineral distribution and some serum parameters of broiler chickens. A total of 200 one-day old Ross 308 chicks were divided into in equal four dietary treatments groups with five replicates each of ten chicks. The experimental groups were given the basal diet (inorganic ZnO), basal diet supplemented with organic Zn (Zn methionine), nano-ZnO and Znmix (organic Zn and nano-ZnO) at a concentration of 50 mg/kg of diet. After 42 days of feeding trial, the group supplemented with nano-ZnO exhibited the best final body weight and feed conversion ratio (2380 g/bird and 1.69, respectively). Nano-ZnO and Zn-mix supplementation significantly increased crude fat retention (86.70 and 86.75%, respectively). All sources of supplemented Zn other than inorganic ZnO significantly increased (P<0.05) Zn retention especially in the group supplemented with nano-ZnO (41.8%). Organic Zn and/or nano-ZnO sources supplemented to broiler diets significantly increased (P<0.05) iron and copper contents in the hepatic tissue and Zn content in the tibia. The mean of serum total cholesterol, triglycerides and very low density lipoprotien were significantly reduced (P<0.05) by dietary supplementation of organic Zn and/or nano-ZnO. The activity of malondialdehyde was significantly decreased (P<0.05), while Cu/Zn superoxide dismutase activity was significantly increased (P<0.05) by addition nano-ZnO or Zn-mix. Dietary Zn-mix and nano-ZnO positively affected mRNA expression of insulin like growth factor-1 and growth hormone genes in broilers when compared to the inorganic ZnO source. The present findings prospected that replacing traditional inorganic ZnO source with nano-ZnO or combining nano-ZnO and Zn methionine at applied concentration, promoted the growth of broilers, enhanced Zn up take and antioxidant status without negative effect on selected minerals distribution in tissues.
