“…Eggshell Zn and Cr concentrations were significantly increased by use of the organic form compared with the inorganic form (15.4 and 50 %, respectively) in this study. These results are in line with those of Idowu et al [33] who reported that supplementation of organic Zn (140 mg/kg Zn proteinate) to the diet of laying hens increased Zn accumulation in eggshell compared with control and inorganic sources (ZnCl 2 , ZnSO 4 , ZnO, and ZnCO). However, supplementation by dietary inorganic or organic Mn, Zn, and Cu complexes (60, 60, and 10 and 30, 30, and 5 mg/kg of Mn, Zn, and Cu, respectively) did not affect Zn concentration in the eggshell [17].…”

“…The highest reduction in mineral levels of feces was observed on comparing the combination of the organic mineral source and low-level dosing with that of the inorganic mineral source and high-level supplementation (which is frequently used in the commercial diets of laying hens) (36.0, 36.4, 46.6, and 6.6 % for Mn, Zn, Cu, and Cr, respectively). These results are in agreement with those of previous researchers who reported that trace mineral excretion correlated with the amounts of these minerals in the diet, excretion reduced with a reduction of dietary minerals [13,23,[32][33][34], and a greater reduction was observed when using minerals from organic sources [13,34]. Yan and Waldroup [6] reported that inorganic trace mineral supplementation of the diets of farm animals resulted in a high level of mineral excretion.…”

In the present study, the effects of dietary supplementation of organic and inorganic Mn, Zn, Cu, and Cr mixtures using two different levels (80, 60, 5, and 0.15 mg/kg and 40, 30, 2.5, and 0.07 mg/kg, respectively) on the bioavailability of these trace minerals and Ca in late-phase laying hens were evaluated. Three hundred and sixty laying hens (Barred Rock) at 50 weeks of age were used, and the duration of study was 16 weeks. Each of the four dietary regimes was randomly assigned to six replicates, which included 15 hens each. Organic trace minerals were provided as methionine chelates; inorganic Mn, Zn, and Cr were provided as oxides; and Cu was provided as sulfate. The organic form significantly increased the concentrations of serum Mn, Zn, Cu, and Ca; egg Mn, Zn, Cu, and Cr; and eggshell Zn and Cr compared with the inorganic form. However, the form of trace minerals did not affect the concentrations of serum Cr and eggshell Mn, Cu, and Ca. High-level addition of trace minerals significantly increased serum Mn and Zn; egg Mn, Zn, Cu, and Cr; and eggshell Mn, Zn, and Cu concentrations compared with low-level addition but did not affect serum Cu, Cr, and Ca or eggshell Cr and Ca concentrations. While the organic form reduced the excretion of Mn, Zn, Cu, Cr, and Ca, the high-level supplement increased Mn, Zn, and Cu excretion. The addition level did not affect Cr and Ca excretion. These results demonstrate that dietary supplementation of an organic Mn, Zn, Cu, and Cr mixture increases the bioavailability of Mn, Zn, Cu, Cr, and Ca compared with inorganic sources and that a lower level of trace mineral supplementation results in lower mineral excretion, particularly in an organic form.

“…Also, there were no significant differences for weight of egg components and shell thickness, but values of albumen height and Haugh units were higher in the groups received organic zinc at 25 or 50 mg/kg than the group fed diet without supplemental zinc ). Egg quality were not significantly differed due to zinc sources except Haugh units values when laying hens fed diets included zinc oxide, zinc sulphate, zinc carbonate and zinc proteinate at level of 140 mg/kg diet (Idowu et al 2011). …”

ABSTRACT:One hundred and twenty Golden Montazah laying hens (Egyptian local developed strain) aged 24 weeks were divided in two groups each group contains four treatments with two different supplemental sources of zinc, inorganic zinc as zinc sulphate (ZnSo4 7H2O) and organic zinc as zinc methionine to get concentration levels 0.0, 50, 100 and 150 mg supplemental zinc/kg diet to investigate the effect of different dietary levels and sources of zinc and their interaction on the zinc concentration of egg, the productive performance, some egg quality and some blood parameters of laying hens were also estimated. The experimental period lasted for 12 weeks in three subsequent interval periods (four weeks each). Results indicated that increasing zinc levels from 0.0 up to 150 mg/kg either as inorganic or organic significantly increased egg zinc concentration without any adverse effect on egg production. The highest concentration of egg zinc was observed for layers fed diet supplemented with 150 mg zinc/ kg diet as an organic Zn (Zn methionine). Supplementing laying hens' diet with zinc as zinc methionine significantly increased egg production. In that, 100mg supplemental zinc as Zn methionine gave the best feed conversion and egg mass. Also, organic zinc supplementation significantly increased plasma zinc, total protein, albumen, and globulin and improved A/G ratio. Albumen index and Haugh unit significantly affected by increasing zinc levels.In conclusion supplemented laying hens diet with 150 mg zinc as zinc methionine / kg diet gave zinc enriched egg which could supply 19.45 % of daily requirements of zinc for children from 1-8 years and additionally gave advancement in productive performance for laying hens.

“…It is estimated that the organic form (polysaccharide zinc complex) or zinc nano particles decreased the amount of free trace mineral ions in the small intestine and calcium and phosphorus were prevented from forming insoluble compounds with these minerals, thereby increasing the absorption of Ca. Idowu et al (2011) similarly reported that organic Zn resulted in higher Ca bioavailability relative to a control group and to inorganic sources.…”

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.
