Details of nano zinc oxide
Nanometer zinc oxide is used as filler, additive and brightener of coatings. In addition to the above properties, the excellent sun protection and isolation ability of nano zinc oxide also has significant characteristics in the aging resistance of building coatings.
Organic solvents used in glass and ceramics. Nanometer zinc oxide particles are fine and highly active, which can reduce the sintering temperature of glass and ceramics. In addition, the ceramic glaze made of nano zinc oxide has more luster, and has the effect of removing mold and odor.
In the electronic industry, it is an important raw material for ceramic chip capacitors and an important addition to magneto-optical materials. The inductors using nano ZnO not only have low sintering temperature, but also can improve the performance of ceramic capacitors, such as oil drain level and nonlinear coefficient. With the in-depth analysis of the optical properties of nano zinc oxide, the application of nano zinc oxide in optical instruments will achieve significant progress. In addition, it can also be used as a toner in the printing and dyeing industry.
From the aspect of humoral immunity and antioxidant activity, it is indicated that the effect of nano zinc added to the diet on broilers. In the feeding experiment lasting for 5 weeks, the creator randomly divided the chicks (Ross308) fed with basic diet into three groups, and gave them 40 mg/Kg inorganic zinc oxide (control experiment), 40 mg/Kg nano zinc oxide (NZ1) or 80 mg/Kg nano zinc oxide (NZ2) respectively.
The chickens were injected with DNP-KLH (2,4-dihydrazine hemocyanin) on the 7th and 21st days after the study, and blood was collected on the 7th, 14th, 21st, 28th and 35th days to measure the levels of human immunoglobulin Y (IgY) and malondialdehyde and their antioxidant enzyme activities. The immune cells were measured according to the percentage and index value of possible blood cell lymphocytes swallowed and the activity of possible T lymphocytes by reticulocyte conversion test.
The results showed that, compared with the experimental group, the addition of nano zinc oxide in the diet could increase (p<0.05) the activity of dismutase, dismutase and enzyme activity, and reduce the content of malondialdehyde in broilers, but there was no significant difference between NZ1 and NZ2 groups. In addition, the serum protein IgY, total lymphocyte count and phagocyte count of chick seedlings fed with nano zinc oxide diet were significantly higher than those in the control experiment (p<0.05).
In general, adding 80mg/kg nano zinc oxide to the diet can improve the antioxidant capacity and cellular immune function of broilers.
