Selenium Rich Yeast Powder A Natural Source Of Organic Selenium For
Laying Hens
Selenium enriched yeast is an organic selenium source developed
using yeast. It is produced by enriching selenium in the cell
protein structure of growing yeast. Selenium enriched yeast has
been proven to be safer, more stable, easier to absorb, more
effective, less polluting, and has multiple health benefits than
inorganic selenium. Therefore, in recent years, its role in animal
nutrition has gradually been recognized, and its application in
animal husbandry and fishery production has become increasingly
widespread.

Advantages of using yeast selenium in laying hens feed:
1. Yeast selenium enhances egg production rate in laying hens
Research has shown that adding an appropriate amount of yeast
selenium (such as 0.2 mg/kg, 0.6 mg/kg) to the basic diet of laying
hens can significantly improve their egg production rate while
reducing the feed to egg ratio. This is because yeast selenium can
promote the growth and development of laying hens, enhance their
metabolic function in the body, and thus improve their egg
production performance.
2. Yeast selenium enhances the anti stress ability of laying hens
Yeast selenium can enhance the activities of plasma glutathione
peroxidase (GSH Px), total superoxide dismutase (T-SOD), and liver
GSH Px, thereby enhancing the total antioxidant capacity of laying
hens. This helps laying hens better adapt and resist environmental
pressure or stress situations.
3. Yeast selenium improves the metabolism of laying hens
The addition of yeast selenium can improve the yolk color, eggshell
strength, and eggshell thickness of eggs, which may be related to
the regulation of yeast selenium on the metabolism of laying hens.
Yeast selenium can promote the absorption and utilization of
nutrients in the body of laying hens, thereby improving their
metabolic levels.
4. Yeast Selenium Improves Selenium Content in Eggs
By adding an appropriate amount of yeast selenium (such as 200g/T)
to the full feed of laying hens, the selenium content in eggs can
reach 0.3-0.5ppm after about 21 days, which is much higher than the
selenium content in regular eggs (0.08-0.15ppm). Due to the protein
chemical composition of eggs being extremely similar to human
proteins, these converted selenium proteins can be well absorbed by
the human body, thus having a positive impact on human health.
In summary, yeast selenium plays an important role in the breeding
of laying hens. Adding an appropriate amount of yeast selenium can
improve the egg production rate, stress resistance, and body
metabolism of laying hens, while significantly increasing the
selenium content in eggs, which has a positive impact on human
health. Therefore, the rational application of yeast selenium in
laying hens breeding can improve breeding efficiency and promote
sustainable development of the breeding industry.
