“…In the present study serum cholesterol concentration was reduced by organic Zn supplementation ( Table-5 ) compared to inorganic Zn supplementation. This observation was supported by Parák and Straková [ 38 ] who stated that Zn supplementation could reduce the blood plasma cholesterol concentration, and the reduction was significantly higher with organic Zn supplementation compared to inorganic. Similarly, Sahin et al .…”

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.

The objective of this study was to determine the optimal dietary chelate of zinc and manganese on the growth performance, blood profile and carcass characteristic. A total number of 1050 unsexed quail chicks aged 7 days and averaged 23.7g body weight were divided randomly into five groups (210 birds each), each group was subdivided into three replicates, each with 70 birds. Birds were kept under the same administrative, healthy and environmental conditions The five treatment groups were fed as follows: The 1st group of birds was fed basal diet and served as control (T1), birds of the 2nd and 3rd groups were fed the same basal diet supplemented with 100 mg zinc tryptophan chelate (T2) and 100 mg zinc proteinate chelate (T3). While birds from the 4th and 5th groups were fed the same diets of control diet supplemented with 100 mg manganese tryptophan chelate (T4) and100 mg manganese proteinate chelate (T5). Feed and water were provided ad libitum throughout the experimental period. The trial lasted 5 weeks. The results indicated that body weight gain and feed conversion coefficient were influenced by supplemental levels of zinc and manganese proteinate chelates, the hemoglobin concentration, packed cell volume and white blood cell were significantly higher in groups T3 and T5. Total cholesterol level, LDL-cholestrol and glucose decreased in T3and T5 treatment ( Zn and Mn proteinate chelate). However, HDL-cholestrol level, Albumin, AST, ALT, ALP and calcium were significantly increase with chelated minerals treatments. The effect of treatment on the carcass traits and relative weight of the lymphoid organs were significantly increased. It is concluded that supplementing diets of Japanese quail with Mn and Zn chelate especially with protein had great influence on performance, blood profile and carcass characteristics as well as improved the immune response

“…= 1, p = 0.02). A negative correlation between zinc and cholesterol has been reported in other bird species (Dean et al 1991;Kucuk et al 2003;Parak and Strakova 2011;Shah et al 2020). However, this observation is not consistent, with other studies reporting positive correlations between zinc and cholesterol in other bird species (Al-Daraji and Amen 2011; Kaya et al 2001).…”

There is growing recognition of the threat posed to wildlife by pollutants. Waterbirds are robust bioindicators of ecosystem health, and metal toxicity is a threat to these species in waterways worldwide. Urban waterbirds are likely to be at the highest risk of heavy metal exposure, but this issue has not been widely explored in Australia. Our aim was to estimate contemporary heavy metal exposure in a sedentary urban waterbird population: black swans (Cygnus atratus) inhabiting an inner-city wetland in one of Australia’s largest cities, Melbourne. To investigate the physiological implications of legacy heavy metal exposure in these birds, we quantified blood biochemistry profiles and examined their relationships with metal concentrations in feathers. We caught 15 swans in 2021 and took feather samples to measure the concentration of eight heavy metals (chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), lead (Pb), and mercury (Hg)), and blood samples to measure the concentration of 13 plasma analytes. Multivariate regression analysis revealed few associations between heavy metals and biochemistry markers, and no differences between sexes or age classes. This study presents a baseline dataset of these contaminants and blood biochemical profiles of swans at this wetland that can be used for future monitoring and is an important step toward a better understanding of the threat posed by heavy metals to Australian urban waterbirds.
