“…There are reports indicating that the addition of Zn in the form of nanoparticles covering only 10% or 20% of recommendations for this element has improved growth performance in chickens, whereas increasing Zn to a level covering 40% of nutritional recommendations did not produce this effect [30]. Reduction of Zn addition to turkey diet from 100 to 50 and 10 mg/kg [31], as well as the lack of Zn addition to chickens diet [32] was not found to affect growth performance. Azad et al [33] reported that a lack of Zn supplementation had an adverse effect on rearing results.…”

The aim of the study was to determine the effectiveness of the combined use of Cu, Zn, and Mn nanoparticles in the diet of turkeys with regard to potential reduction of the levels of these elements added to feed. The experiment was carried out on turkeys’ hens assigned to four groups. Turkeys from the PC group received feed with the addition of inorganic forms of Cu, Zn, and Mn in the B.U.T. (British United Turkeys) recommended levels, from group IR received the addition in amounts reduced to 10% of the recommended levels, and from group NR received the addition of elements in the form of nanoparticles in the same amounts as in group IR. The turkeys from group NC received feed without the addition of these elements. The research showed that the addition of Cu, Zn, and Mn to turkey diets, in both inorganic forms and as nanoparticles, in quantities covering only 10% of B.U.T. recommendations had no adverse effect on growth performance or on the antioxidant and immune defense of turkeys. The changes in the redox status of the turkeys whose diet was not supplemented with Cu, Zn, and Mn indicate reduced oxidation processes in the tissues.

“…Zinc plays a vital role in protecting the body from free radical and oxidative stress, by enhancing the activity of SOD ( Bray and Bettger, 1990 ; Coudray et al, 1992 ). The increased antioxidant capacity by Zn supplementation has been observed in broilers, broiler breeders and turkeys ( Akhavan-Salamata and Ghasemib, 2019 ; Huang et al, 2019 ; Jankowski et al, 2019 ). The current study found that goose breeders fed the diets supplemented with 45 mg/kg Zn showed greater T-SOD than the other groups.…”

“…Zinc ( Zn ) is one of the essential trace mineral of poultry nutrition, and act as component of more than 300 enzymes that are involved in the metabolism of energy and protein ( Jurowski et al, 2014 ; Huang et al, 2019 ). Zn is required for growth, reproduction, bone development, and intestinal health ( Jankowski et al, 2019 ; De Grande et al, 2020 ). The concentration and bioavailability of Zn in many feed-stuffs for poultries are low, dietary supplementation with Zn is usually recommended.…”
