“…One of the important findings of the present study is that the organic sources of Zn, ZnGly, and ZnPOS increased Zn absorption. Similar results have been reported in other studies (Star et al 2012;Sirri et al 2016). How and to what degree the Zn absorption is affected by organic Zn form may depend on other interacting factors including the degree of chelation and the ratio of ligand to the minerals (Thomason et al 1976).…”

. (2018): Effects of zinc sources and levels on zinc bioavailability, blood parameters, and nutrient balance of male mink (Neovison vison). Czech J. Anim. Sci., 63, 174-181.The objective of this study was to investigate the effects of different sources and levels of zinc (Zn) on nutrient digestibility, plasma metabolites, and relative Zn bioavailability in male mink. Animals in the control group were fed a basal diet, consisting mainly of corn, soybean oil, meat and bone meal, and fish meal, with no Zn supplementation. Mink in the other 9 treatments were fed the basal diet supplemented with Zn from grade Zn sulfate (ZnSO 4 . 7H 2 O), Zn glycinate (ZnGly), or Zn pectin oligosaccharides (ZnPOS) chelate at concentrations of either 100, 300, or 900 mg Zn/kg dry matter. The results showed that zinc levels increased the AD of fat linearly (P < 0.05). The AD of fat in Zn-900 was higher (P < 0.05) than that of the control. Fecal Zn and urinary Zn were affected by dietary Zn addition (P < 0.01). Moreover, Zn supplementation increased Zn retention compared with the control group (P < 0.05). The N retention in ZnPOS was higher (P < 0.05) than that of the control. The effect of Zn level was linear (P < 0.01) for N retention. In addition, the activity of alkaline phosphatase was higher in groups supplemented with 900 mg/kg Zn (P < 0.05) compared with the control group. There were significant interactions (P < 0.05) among Zn sources on the activity of Cu-Zn superoxide dismutase (Cu-ZnSOD). Compared with ZnSO 4 , relative bioavailability values were 148% and 173% for ZnGly and ZnPOS, respectively, based on Cu-ZnSOD activity. In conclusion, our data show that the relative bioavailability of ZnPOS was greater than that of ZnSO 4 . 7H 2 O and ZnGly and Zn supplementation can enhance the Cu-ZnSOD of male mink, and mink can efficiently utilize ZnGly and ZnPOS.Keywords: zinc pectin oligosaccharides chelate; nutrient digestibility; relative bioavailability List of abbreviations: ZnPOS = zinc pectin oligosaccharides chelate, ZnGly = zinc glycinate, DM = dry matter, CP = crude protein, EE = ether extract, AD = apparent digestibility, ALP = alkaline phosphatase, ALB = albumin, ALT = alanine transaminase, TP = total protein, GGT = glutamyl transpeptidase, AST = aspartate aminotransferase, GLU = glucose, Cu-ZnSOD = Cu-Zn superoxide dismutase, GSH-Px = glutathione peroxidase

“…Zn deficiency causes numerous physical and pathological changes such as growth retardation, poor feathering, and decreased immunity to infection of several diseases (Star et al 2012). For carnivores such cat, mink, and ferret, a high level of dietary zinc (50 to 100 mg/kg diet) is required for optimum fetal development compared to other animal species.…”

“…Similarly, Sunder et al (2008) reported that a basal diet containing 29 ppm Zn was enough to support maximum bird performance. Additionally, as suggested by Star et al (2012), lack of response on FC and BWG in our study, could be due to the short duration of the experiment and imprinting period, and future research to test the effect of prolonged imprinting periods on performance will be of interest.…”

The goal of this study was to determine the effects of feeding a zinc (Zn) deficient diet to broiler chicks for 96 h post-hatch followed by feeding diets with different Zn sources and supplemental levels (5 to 21 d) on the growth performance, tissue, and excreta Zn content. At the start of the study, four hundred 20-day-old male broiler chicks were divided into two groups. One group was fed a corn soybean meal based diet containing 25 mg of Zn/kg (imprinting diet, ID). The second group was fed the basal diet supplemented with 40 mg of Zn/kg from Zn oxide (ZnO) (non-imprinting diet, NID). Both groups were fed these diets for 96 h. At d 5, chicks from each group were randomly assigned to the dietary treatments consisting of the basal diet alone or the basal diet supplemented with 8 or 40 mg/kg Zn as ZnO or Zn proteinate. Main effects of post-hatch Zn ID were observed on feed intake and G:F. ID decreased (P < 0.05) feed intake and improved (P < 0.05) the gain to feed ratio (G:F) of 14 and 21 d old chicks compared to G:F of chicks fed NID. Additionally, G:F for 14 and 21 d was improved (P < 0.05) by interaction of Zn source × level. Furthermore, at d 21 chicks fed the ID had a lower (P < 0.05) Zn content in the tibia ash and excreta, and a higher (P < 0.05) Zn content in the pancreas tissue compared to chicks fed NID. These results suggest that Zn imprinting can affect body Zn stores and early performance.

The aim of this study was to investigate the effect of dietary supplementation of nanosize zinc on zinc digestibility, growth performances, immune response and serum parameters of weanling piglets. Ninety-six LYD weanling piglets were assigned to control, zinc oxide (ZnO), organic-Zn (Zn-methionine) and nanosize ZnO (nano-Zn) groups with four replicates. The zinc was at the 120 mg/kg level in the treatment group's diet, while the control group's was 80 mg/kg Zn. The experiment results indicated that the nano-Zn and organic-Zn groups had significantly higher Zn digestibility compared to the ZnO and control groups. For the immune response traits, the IgG level and goat red blood cells (GRBC) antibody titer were nano-Zn and organic-Zn>ZnO>control; in the phytohemagglutinin (PHA) challenge test result, nano-Zn>organic-Zn>ZnO>control; in regard to the γ-globulin level, nano-Zn and organic-Zn>ZnO and control, with significant difference between groups. In the serum parameters aspect, serum Zn concentration in nano-Zn and organic-Zn groups were higher than in the ZnO and control groups, serum growth hormone concentration was increased in the nano-Zn group than in the other groups. In conclusion, nanosize zinc oxide for dietary supplementation can increase zinc digestibility, serum growth hormone levels and carbonic anhydrase activity and enhance the immune response of weanling piglets.
