“…These discrepancies among the studies may be related to factors such as the type of basal diets, the level of Zn (deficiency or adequacy) in basal diets, the purity of Zn sources, and the content or availability of other minerals [13,51]. For example, the dissimilar action of dietary Zn supplementation may be due to different interferences from various concentrations of other minerals (e.g., Ca, Fe, Cu, and P) in different studies.…”

IntroductionMethane released during ruminal fermentation plays an important role in global warming [1,2]. One of the aims in ruminant nutrition is to reduce the release of methane from the rumen, without adverse effects on digestibility, animal health, and productivity [3]. Moreover, improvements of rumen microbial biomass and the antioxidant status of animals are attractive targets in feeding management. This requires the best supply of nutrients and supplementary minerals in diets. Zinc is a vital trace mineral needed for animal productivity, immunity, rumen metabolism, and the antioxidant system [3][4][5]. Zn insufficiency can cause the weakness of the antioxidant system [6-8] and using high levels of dietary trace minerals, such as Zn, can improve animal health and performance [9][10][11][12].Diets are usually supplemented with Zn as inorganic (such as ZnO and ZnSO 4 ) or organic (such as Zn-amino acid complexes) sources. An organic mineral source offers further elements to animals due to its superior bioavailability [5,13]. At present, the usage of ZnO nanoparticles (nano-ZnO), with sizes of 1 to 100 nm, has increased in various fields such as mineral nutrition in livestock [4,7,14]. Nano sources of trace minerals have high bioavailability because of interesting properties such as the nano scale size, rapid and specific movement, higher area surface to volume proportion, surface activity, catalytic effectiveness, and absorption percentage [12,15,16]. Some researchers assessed the toxic impacts of Zn nanoparticles in animals [17][18][19]. However, there are studies supporting the beneficial effects of nanoparticles on animal performance, feed efficiency, and health as well as reduction of environmental pollution, due to the great bioavailability [15,16,20,21]. Wang et al. [12] mentioned that long-term oral Zn sulfate treatment was more toxic for animals than nano-ZnO. As reported by Singh et al.[22], feeding preruminant lambs with nano-ZnO instead of ZnO increased the Zn availability without causing toxicity. Nano-ZnO can improve villus height, crypt depth, and villus surface area in the gastrointestinal tract [12,14]. Sarker et al. [1] reported that supplementation with high levels of nano-ZnO (i.e. 500 and 1000 μg/g) decreased in vitro methane concentration compared with a control treatment (no Zn supplementation). Nanoparticles could be poisonous to certain microbes generating methane in anaerobic digestion [14,23]. Still, further studies are necessary to realize the possible helpful or harmful effects of nano-ZnO on animals [1,7,21].

“…Although DM, OM, and NDF digestibility did not differ due to source in the current study, ADF digestibility tended to be lesser for ZS compared with GLY. Others have also reported improvements in ADF digestibility when an organic (Zn–Met and Zn–proteinate) source was compared with an inorganic (ZS) source ( Garg et al, 2008 ; Alimohamady et al, 2019 ). High concentrations of Zn have been shown to lessen the rate and extent of cellulose digestion in vitro potentially due to inhibition of cellulolytic enzymes ( Eryavuz and Dehority, 2009 ).…”

To assess efficacy of bis-glycinate bound Zn, 36 crossbred wethers (34 ± 2 kg) were sorted by body weight into three groups and stagger started on a Zn deficient diet (18 mg Zn/kg dry matter; 22.5% neutral detergent fiber) for 45 d prior to a 15-d metabolism period (10 d adaptation, 5 d collection). On d 46, lambs were randomly assigned to dietary treatments (4 lambs treatment-1group -1): no supplemental Zn (CON) or 15 mg supplemental Zn/kg dry matter (ZINC) as Zn sulfate (ZS) or bis-glycinate (GLY; Plexomin Zn, Phytobiotics). Blood was collected from all lambs on d 1, 44, 56, and 61. Liver, jejunum, and longissimus dorsi samples were collected after euthanasia on d 61. Gene expression was determined via quantitative real-time polymerase chain reaction. Data were analyzed using ProcMixed of SAS (experimental unit = lamb; fixed effects = treatment, group, and breed) and contrast statements assessed the effects of supplemental Zn concentration (ZINC vs. CON) and source (GLY vs. ZS). After 15 d of Zn supplementation, plasma Zn concentrations were greater for ZINC vs. CON and GLY vs. ZS (P ≤ 0.01); tissue Zn concentrations were unaffected (P ≥ 0.27). Liver Cu concentrations were lesser for ZINC vs. CON (P = 0.03). Longissimus dorsi Mn concentrations were greater for ZINC vs. CON (P = 0.05) and tended to be lesser for GLY vs. ZS (P = 0.09). Digestibility of DM, OM, and NDF was lesser for ZINC vs. CON (P ≤ 0.05); ADF digestibility tended to be greater for GLY vs. ZS (P = 0.06). Nitrogen retention (g/d) tended to be greater for GLY vs. ZS (P = 0.10) and N apparent absorption was lesser for ZINC vs. CON (P = 0.02). Zinc intake, fecal output, retention, and apparent absorption were greater for ZINC vs. CON (P ≤ 0.01). Apparent absorption of Zn was -5.1, 12.8, and 15.0% for CON, ZS, and GLY, respectively. Nitrogen and Zn retention and apparent absorption were not correlated for CON (P ≥ 0.14) but were positively correlated for ZINC (retention P = 0.02, r = 0.52; apparent absorption P < 0.01, r = 0.73). Intestinal expression of Zn transporter ZIP4 was lesser for ZINC vs. CON (P = 0.02). Liver expression of metallothionein-1 (MT1) tended to be greater for GLY vs. ZS (P = 0.07). Although Zn apparent absorption did not differ between sources (P = 0.71), differences in post-absorptive metabolism may be responsible for greater plasma Zn concentrations and liver MT1 expression for GLY supplemented lambs, suggesting improved bioavailability of GLY relative to ZS.

The morphology of nanomaterials is an important factor to determine their properties. In this study, zinc oxide (ZnO) and cupric oxide (CuO) nanoparticles were synthesized via the co-precipitation method with the same protocols. Zinc nitrate and copper sulfate were selected as ZnO and CuO precursors, respectively. Then, the phase structure and morphology of both prepared nanoparticles were investigated and showed that ZnO and CuO were prepared without any impurities and with different morphologies. The obtained ZnO and CuO nanoparticles illustrated sphere-like and hierarchical flower-like structures, respectively, due to their various phase structure and electrostatic interactions.
