Inorganic selenium and organic selenium are usually added to poultry diets with inorganic selenium sodium selenite, but due to their strong toxicity, they bring many inconveniences to production and use. On the one hand, inorganic selenium is absorbed through the intestinal wall through passive diffusion and then enters the liver, where it is converted into biological selenium, with low bioavailability. At the same time, a large amount of unused inorganic selenium is discharged into the environment, causing serious environmental pollution. On the other hand, the dosage of inorganic selenium is difficult to control, and livestock and poultry, especially young animals, are more sensitive to selenium Sensitive and prone to poisoning.
At present, there are many types of organic selenium on the market, including selenium amino acid forms and yeast selenium. Compared with inorganic selenium, organic selenium has lower toxicity and is easy to apply in feed. Organic selenium is absorbed and utilized by the body through the intestinal wall through an active transport mechanism, with a higher absorption rate than inorganic selenium. It can reduce the amount of selenium added to feed and reduce environmental pollution caused by selenium.
Nano selenium is an element with zero valence state up to the nanometer level (within 60nm) and excellent nanoscale properties, appearing as a stable red powder. Nano selenium particles are uniform and small, with a large surface area and multiple surface unsaturated bonds. They have high surface activity and high adhesion in the gastrointestinal mucosa, making them easily absorbed by animal intestines and having high biological utilization rates.
Nano selenium has a wider dosage range in enhancing the antioxidant and immune functions of animal bodies compared to organic selenium such as sodium selenate and selenomethionine, and its immune efficacy is higher than that of selenomethionine and sodium selenite.
Product features
1. Compared with organic selenium such as yeast selenium, it exhibits higher absorption and deposition efficiency in various animals.
1. Due to its specific nanoscale properties, its efficient biological action has a wider range of doses and is safer to use.
3. Nano selenium exhibits higher efficiency and safer dosage range in terms of antioxidant function, thereby improving the quality of livestock products and extending shelf life.
4. Better improve the uniformity of livestock and poultry growth.
5. Mori selenium has a higher cost-effectiveness than other selenium sources such as yeast selenium.
6. Molybdenum selenium can be easily and clearly detected, while yeast selenium active ingredient (selenomethionine) is not suitable for detection, and there are significant differences in selenomethionine between different manufacturers and batches.
Usage and Dosage:
According to different purposes of use, the following three recommended usage methods
1. Nutritional Dosage: 50-100g/t;
2. Dosage for disease resistance: 100-200g/t;
3. Selenium rich dosage: 200-500g/t.
