Sodium Selenite Na2SeO3 Offwhite Powder Animal Feed Additive CAS 10102-18-8

Product Name: Sodium Selenite

Molecular formula: Na2SeO3

Molecular weight: 172.95

Physical and chemical properties: milky white powder, soluble in water, no lumps, good fluidity

Product Description: Selenium is an essential trace mineral for animal growth and development, effectively alleviating oxidative stress. Selenium is added to feed in very low doses (less than 1mg/kg per ton of feed), requiring extremely high fineness and uniform mixing of the active ingredient. Chengdu Shuxing Feed, taking into account the characteristics of selenium, has developed a low-dust, environmentally friendly, and non-toxic selenium diluent product to help animals efficiently supplement selenium and improve their health.

Product technical points:

v The raw materials are high-quality imported selenium raw materials, and the content of heavy metals such as arsenic, lead, chromium and mercury is far lower than the national standard. It is safe, environmentally friendly and non-toxic.

v The raw material of sodium selenite is crushed by ultra-fine ball milling equipment, and the particle size can reach 400-600 mesh, which greatly improves the solubility and bioavailability

v We use the diluents and carriers developed by our company to ensure the fluidity and uniformity of the product through gradient dilution and multiple mixing. The excellent fluidity ensures uniform distribution in the feed.

v Use advanced ball milling technology to reduce dust release

Product Benefits :

v Selenium, as a component of glutathione peroxidase, improves the antioxidant capacity of animals

v Can regulate the secretion of reproductive hormones and improve reproductive performance

v Promote muscle protein synthesis and promote animal growth

v Improve the body’s immunity and enhance disease resistance

v Improve selenium deposition, produce selenium-rich products, and increase product added value

Animal applications:

1) pig

Enterotoxigenic Escherichia coli (ETEC ) can cause diarrhea in piglets. Studies have shown that adding selenium to piglet diets reduces lipopolysaccharide synthesis in the ileal microbiome, reducing the diarrhea index and diarrhea rate in piglets.

2) laying hens

Adding sodium selenite to laying hen diets can improve the growth performance of laying hens, extend the shelf life and selenium content in eggs, and increase the nutritional value of eggs.

3) ruminants

Adding selenium to Hu sheep can not only increase the selenium content in tissues and produce selenium-rich mutton; it can also increase the total antioxidant capacity of serum, reduce the level of malondialdehyde, and improve the ability to resist stress.
