“…On the other hand, the current results do not agree with several other findings where low-level supplementation with Zn from organic sources increases serum Zn, P or Ca concentration [ 14 , 17 , 19 , 41 – 43 , 61 , 66 ]. There are also recent studies showing no effect of dietary Zn on plasma Zn and Cu concentration [ 44 , 48 , 67 ]. However, in the present study, Zn, Fe and Ca concentrations increased after phytase inclusion when compared to both control groups, irrespective of Zn supplementation.…”

Zinc is required for normal bone development and cartilage formation. The purpose of this study was to assess the effect of with adding organic Zn (alone or phytase inclusion) at the reduced dose to growing male Ross 308 chickens on somatic axis and bone tissue metabolism. 200 one-day old broilers were divided into the negative control group fed diet without Zn or phytase inclusion, positive control group receiving Zn in the 100% of daily recommended dose from ZnO, and two experimental groups fed diet introduced Zn in 25% of daily recommendation as a glycine chelate (Zn-Gly) with or without phytase inclusion (500 FTUÁkg -1 ). Supplemental organic Zn increased bone Zn and Mg content, serum IGF-1, growth hormone and leptin concentration. Additional phytase inclusion increased body weight gain, blood plasma Ca, Fe, Zn and osteocalcin concentration and tibia ash percentage when compared to the Zn-deprived control. Bone geometry, yield and ultimate strengths were enhanced in both organic Zn supplemented groups, and the overall mechanical strength parameters of bone were better in these groups than in the positive control group supplemented with standard dose of inorganic Zn. Also marked improvements in the thickness of articular and the growth plate cartilages as well as real bone volume and thickness of metaphyseal trabeculae were achieved in all broilers fed Zn-supplemented diet irrespective of phytase inclusion, however, the highest cancellous bone mass and the best trabecular structure were noted after ZnO supplementation. In concludion, although dietary organic Zn given to growing broilers in 25% of daily recommended dose improved general bone properties and mechanical strength, the obtained results do not allow to unambiguously state that organic Zn supplementation at this level, even after phytase inclusion, is sufficient for proper bone development.

“…Also, Mwangi et al [43] specified that increasing dietary Zn and Mn supplementation were desired for a higher mineral storage in the liver. Ivanišinová, et al [44] reported that higher bioavailability of organic Zn associated with its higher concentration in the hepatic tissues. It was described that zinc influenced the absorption and biodistribution of Cu, Fe and Mn trace minerals [45].…”

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.

“…Recent data have indicated that inclusion of organic Zn sources in rabbit diets could improve growth performance and duodenum morphology, as well as reducing the incidence of diarrhoea in growing rabbits (Yan et al, 2017). However, some studies have shown no differences in the bioavailability of Zn between organic and inorganic sources (Ivanišinová et al, 2016). Our previous work demonstrated that dietary supplementation with 100 mg Zn/kg from inorganic or organic sources resulted in a significant increase in digestibility coefficients of Zn, Fe and Mn compared to unsupplemented rabbits and did not influence selected biochemical parameters in caecal fermentation (Chrastinová et al, 2016).…”

The purpose of this study was to compare the effect of dietary zinc from inorganic and organic sources on the concentration of Zn, Cu, Mn and Fe in plasma, tissues and faeces of rabbits. Simultaneously, the activities of total superoxide dismutase (SOD), specific Cu/Zn SOD, glutathione peroxidase (GPx), lipid peroxidation and total antioxidant capacity (TAC) in liver and kidney were also determined. Ninety-six 49-day-old broiler rabbits were allocated to 4 dietary treatments, each replicated 6 times with 4 animals per replicate. For the subsequent 6 wk, the rabbits were fed an identical basal diet (BD) supplemented with an equivalent dose of Zn (100 mg/kg) from different sources. Group 1 (control) received the unsupplemented BD, while the BD for groups 2, 3 and 4 was supplemented with Zn from Zn sulphate, Zn chelate of glycine hydrate (Zn-Gly) and Zn chelate of protein hydrolysate (Zn-Pro), respectively. The intake of dietary Zn sulphate resulted in an increase in Zn plasma concentration (1.85 vs. 1.48 mg/L; P<0.05) compared to the control group. Feeding the diets enriched with Zn increased the deposition of Zn in the liver (P<0.05), irrespective of the Zn source. The addition of Zn-Pro resulted in significantly higher Cu uptake in liver (P<0.05) than in the control and Zn sulphate group (56.0 vs. 35.0 and 36.7 mg/kg dry matter (DM), respectively). Neither Mn nor Fe concentration in plasma and tissues were affected by dietary Zn supplementation, with the exception of Fe deposition in muscle, which was significantly decreased (P<0.05) in rabbits supplemented with inorganic Zn sulphate compared to control and Zn-Gly group (9.8 vs. 13.3 and 12.2 mg/kg DM, respectively). Intake of organic Zn-Gly significantly increased the activities of total SOD (43.9 vs. 35.9 U/mg protein; P<0.05) and Cu/Zn SOD (31.1 vs. 23.8 U/mg protein; P<0.01) as well as TAC (37.8 vs. 31.2 μmol/g protein; P<0.05) in the kidney when compared to that of the control group. The presented results did not indicate any differences between dietary Zn sources in Zn deposition and measured antioxidant indices in rabbit tissues. Higher dietary Zn intake did not cause any interactions with respect to Mn, Cu and Fe deposition in liver and kidney tissues, but did increase the faecal mineral concentrations. Dietary organic Zn-Gly improved the antioxidant status in rabbit kidney.
