“…However, contrary to the ndings of present study, Chang et al[71] showed that supplementation with Zn-methionine but not ZnO, signi cantly increased the ADG of new-born calves in the rst 2 week after birth. Anil et al[72] observed signi cantly higher body weight gain and ADG in the 20 ppm nano Zn supplemented calves group followed by 10 ppm nano Zn, 5 ppm nano Zn supplemented groups and 25 ppm ZnSO 4 group. Hongfu et al[73] observed signi cant increase in ADG in nano-Zn oxide (200,400, and 600 mg/kg) supplemented group and higher ZnO (3000 mg/kg) supplemented piglet groups compared to the no Zn supplemented group.…”

This study was conducted to evaluate the effect of nano copper (nano-Cu) and nano zinc (nano-Zn) supplementation on the biomarkers of immunity and antioxidant and health status attributes in young dairy calves. Twenty-four young cattle calves were randomly assigned into four groups (6 calves per group) on body weight and age basis for a period of 120 days. Feeding regimen was same in all the groups except that these were supplemented with 0.0 mg nano Cu and nano Zn (control), 10 mg nano Cu (nanoCu10), 32 mg nano Zn (nanoZn32) and combination of nano Cu and nano Zn (nanoCu10+nanoZn32) per kg dry matter (DM) basis in four respective groups. Supplementation of nano Cu along with nano Zn improves immune response which was evidenced from higher immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), total immunoglobulin (TIg) and Zn sulphate turbidity (ZST) units and lower plasma concentrations of tumour necrosis factor-α (TNF-α) and cortisol in nanoCu10+nanoZn32 group. There were no effect of treatment on the plasma concentrations of immunoglobulin E (IgE) and interferon gamma (IFN-γ). Antioxidant status was also better in the nanoCu10+nanoZn32 group as evidenced from lower concentrations of malondialdehyde (MDA) and higher activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), ceruloplasmin (Cp) and total antioxidant status (TAS). However, treatment did not exert any effect on catalase (CAT) activity. Although the nano Cu or nano Zn supplementation, either alone or in combination, did not exert any effect on growth performance or body condition score (BCS) but frequency of diarrhea and incidence of diarrhea was lower while faecal consistency score (FCS) and attitude score were better in the nanoCu10+nanoZn32 groups. In control group, one calves found affected with joint ill and two calves were found affected with navel ill. During the experimental period, none of the calf in all four groups was found affected with pneumonia. The findings of this study revealed that, dietary supplementation of nano Cu in combination with nano Zn improved the health status of young dairy calves by improving immunity and antioxidant status.

“…The performance of growing animals is severely affected even upon a minute deficiency of trace minerals and zinc is not an exception. (Anil et al, 2019) Nano engineered product, the Nano zinc oxide (nZnO), a new form of zinc metal has been designed by using the principles of nanotechnology where the size, shape and crystalline structure of the metal are manipulated by various methods of preparation (Swain et al, 2016).…”

This study was conducted to evaluate the effect of Nano zinc oxide particles (nZnO) supplementation on growth performance, ingestive and standing idle behaviours, serum zinc level and some haematological parameters in cross bred calves. Ten calves at the farm of Faculty of Veterinary Medicine -Aswan University were randomly selected within an average age of 4 months and weight of (70.3±5.3 kg). Calves were divided equally into two groups, control, and treated groups (n=5) in each group. Each treated calf was administered daily with zinc oxide Nano particles at the rate of (10µg/g ) orally for three months. The results revealed that the used rate of nZnO supplementation had no significant effect on the average daily gain of calves throughout the different periods of experiment. Moreover, the average time spent in ingestive behaviour was significantly higher in control group (18.1±0.3 and 16.8±1.4 min ) than treated group (11±2.1 and 5.7±3 min ) after 2 weeks and 8 weeks respectively. On the other hand, serum zinc level was significantly higher (p<0.05) in the treated group (9.2±0.4 µg/dl) than control group (8.0±0.2 µg/dl) after the 12 th week. There was no significant effect of nZnO supplementation on the other measured hematological parameters. In conclusion, nZnO supplementation may have a little effect on ingestive and standing idle behaviour but it has no pronounced effect on growth performance, serum zinc level and some haematological parameters in calves.
