Background

Part 1

According to statistics, the annual average incidence of piglets under 30KG is 46.5%, among which 39.8% are caused by diarrhea, which shows the great impact of diarrhea on the breeding industry

Part 2

Since the 1980s, it has been found that high zinc (3000ppm) has a better antidiarrheal effect than high copper (250ppm)

Part3

The anti-diarrhea effect of zinc oxide is based on molecular form (ZnO) rather than bivalent zinc ion (Zn2+), so the anti-diarrhea effect of adding the same dose of other zinc sources cannot be equal to adding the same dose of zinc oxide

Product

Nano Zinc Oxide

Role and significance

(1) high biological activity

Due to its small particle size, nano-zinc oxide can penetrate the tissue gap, also through the smallest capillaries in the body, and the distribution in the body is very wide, which can greatly improve the bioavailability of feed materials.Compared with other zinc sources, nano zinc oxide has more efficient biological activity.

(2) high absorption rate

Due to the size and fineness of nano-zinc oxide, when the particle size decreases, the number of atoms on the surface increases rapidly, which can increase the surface area exposed to the medium and improve the absorption rate of the animal.De-sai mouse experiment shows that the absorption rate of 100nm particle is 10-250 times higher than other large particles.

(3) high oxidation resistance

Because nano-zinc oxide has strong chemical activity, it can oxidize a variety of organic matter including organic matter in bacteria, and kill most bacteria and viruses.The main mechanism of action is as follows: nano-zinc oxide will produce conduction band electron and valence band hole under light condition, which can react with H2O or OH- ions adsorption on the surface to generate hydroxyl group with strong oxidation property, thus killing the cells.The qualitative test showed that the bactericidal rate of glucococcus aureus and escherichia coli was 98.86% and 99.93%, respectively, when the concentration of nano-zinc oxide was 1% and 5min respectively.

(4) high security

Nanometer zinc oxide feed additive can not only feed the animal itself without drug resistance, but also rely on its own large specific surface area, adsorption feed mildew and other processes produced mycotoxin, so that even if the animals eat some moldy feed, also can be adsorbed in the animal gastrointestinal tract, without pathological conditions.

(5) strong immunomodulatory ability

Nano-zinc oxide can significantly stimulate the cell, humoral and non-specific immune function of the organism, and improve the disease prevention and resistance function of the animal body.

(6) it can reduce environmental pollution and remove pesticide residues

, because of the large specific surface area of nano zinc oxide can be effectively adsorbed ammonia, sulphur dioxide, methane, organophosphorus pesticides and organic matter in waste water to the surface, and the use of high intensity of ultraviolet light absorption for photocatalytic degradation of these materials, purification of air and waste water farms, quickly absorb and decompose the stench of farms, which has a protective effect on the surrounding environment.

(7) promote and regulate animal metabolism

Nano-zinc oxide, through its efficient absorption and utilization, induces changes in zinc-containing enzyme levels, zinc-related hormone secretion and zinc lipoprotein.Through affecting the synthesis and level of insulin, sex hormone and zinc finger protein, it can promote the synthesis of protein, improve the utilization efficiency of nitrogen in animals, reduce the excretion of feces and urine nitrogen, and reduce the pollution of nitrogen to the environment, which can better improve the production performance of animal breeding.
