“…This is consistent with Liu et al (2011), who stated that dietary Zn levels and sources did not influence the abdominal fat percentage or the carcass traits of broilers. Rossi et al (2007) and Anil et al (2012b) reported that carcass yields were Savari et al (2015) concluded that there was no influence of ZnO on carcass traits.…”

“…Jahnian & Rasouli (2015) reported no effects on plasma zinc concentration when inorganic zinc was replaced by Zn-methionine. Increased blood Zn levels are used as an indication of its biological availability in live animals (Liu et al, 2011). Similar findings were reported by Mohanna & Nys (1999) and , who observed that blood Zn concentration increased with dietary Zn content.…”

“…Zinc (Zn) is an essential trace element in all living systems -from bacteria, plants and animals to humans -and plays an important role in various biological activities in animals, especially in fast-growing poultry (Liu et al, 2011). Poultry diets are commonly supplemented with Zn since many feed ingredients are marginally deficient in this trace element (Bao et al, 2007).…”

A total of 400 one-day-old, straight-run, commercial (Ross 308) broiler chicks were used to evaluate the effects of two dietary levels of zinc (Zn) sources on broiler chick performance, carcass traits and blood parameters. Corn-soybean diets were formulated for three rearing phases (starter, grower and finisher). The two dietary treatments applied consisted of the addition per kg of diet of 80mg of inorganic Zn (ZnO) (T1), or 80mg of ZnO plus 42mg of an organic Zn-amino acid complex (Availa-Zn120; Zinpro Corporation, Eden Prairie, MN, USA), totaling 122mg of the combined organic and inorganic Zn sources (T2). Birds were distributed according to a completely randomized design in the two treatments with eight replicates (pens) of 25 birds each. Feed and water were provided ad libitum. On day 42, blood samples were taken from four birds closest to the group average weight per replicate (32 per treatment) and then slaughtered for carcass evaluation. The results of this study did not find any significant effect of either of the evaluated Zn sources on broiler growth performance. Mortality rate was significantly lower (p<0.05) by the higher Zn concentration and the Zn sources group (T2). Carcass yields were not significantly influenced by the treatments. Breast quality showed significant improvement (p<0.05) in shear force (T2), indicating juicier meat. Higher concentrations (p<0.05) of Zn, Phosphorus (P), and total protein in blood were noted in (T2). Birds fed a mixture of organic and inorganic Zn source (T2) presented overall better results.

“…Furthermore, Zn enzymes are involved in the synthesis and/or breaking down of carbohydrates, lipids, proteins, and nucleic acids, and encompass all known classes of enzymes (Liu et al, 2011). The recommended Zn requirement that is based on performance criterion for broiler chickens is 40mg/kg of diet Nation Research Council (NRC, 1994).…”

Key words:Broiler chickensOrganic zinc -Nano zinc -Growth performance -Immune response -Intestinal health.Two hundred and twenty-five one day-old avian chicks were used to investigate the effect of different dietary supplemental zinc sources and levels on growth performance, blood picture and biochemical parameters, immune response, carcass characteristics and intestinal morphology of broiler chickens. Birds were randomly allocated into 9 groups which fed on the experimental basal diet supplemented with different zinc sources and levels; group 1 was fed basal diet supplemented with (60 ppm) inorganic zinc oxide, while groups 2, 3, 4 and 5 were supplemented with (60, 45, 30 or 15 ppm) organic zinc (polysaccharide-zinc complex) respectively and groups 6, 7, 8 and 9 were supplemented with (60, 45, 30 or 15ppm) zinc oxide nanoparticles respectively. Broiler chickens fed 60 or 45 ppm organic zinc improved growth performance while, lower supplementation levels (30 or 15ppm) had no significant effect. Moreover, zinc nanoparticles supplementation at 60, 45 or 30 ppm improved growth performance while lower level (15ppm) significantly reduced broiler performance and feed efficiency parameters. Using organic or nano zinc reduced total feed intake of broiler chicken. Organic or nano zinc supplementation non-significantly reduced blood serum lipids and increased GOT or GPT concentrations compared with those fed on diet supplemented with inorganic zinc. Moreover, organic or nano zinc had no significant effect on antioxidant enzyme activity while reduced abdominal fat weight. Organic zinc or nano zinc supplementation improved phagocytic activity, antibody production against Newcastle Disease vaccine, lymphoid organs weight and improve intestinal villi length, width and crypt depth of broiler chicken.

“…It is possible that dietary Zn concentrations enhanced digestibility of fat by stimulating activities of the fat metabolism-related enzymes. Liu et al (2011) suggested that dietary Zn supplementation improved Zn status and resulted in promoting antioxidant ability and activities and gene expressions of fat metabolism-related enzymes of broilers. Similar results have been reported in mink (Bleavins et al 1983) and nursery pigs (Hill et al 2014).…”

. (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
