Energizing soil and livestock with the power of microbial fermentation.
Bio Charger is a material that uses microbial fermentation to improve soil and animal-rearing environments. It supports farming and livestock that don’t over-rely on chemicals, right from the ground up.
Bio Charger A (A = “A-feed”)
For livestock feed. The “A” stands for “A-feed,” which contains no animal-derived ingredients, so it can be used with confidence even for ruminants such as cattle. Through microbial fermentation, it draws out the innate strength of animals and supports a healthy rearing environment.
Kamiya Livestock (pig farming), Okinawa|Bio Charger A 4 years of continuous use
At the Okinawa pig farm “Kamiya Livestock,” Bio Charger A has been used 4 yearscontinuously. The very fact that it has been used for so long speaks to its real-world results and ease of ongoing use.
- Odor (ammonia) from the barn and manure pit has eased greatly, making daily tasks such as cleaning more comfortable.
- A better gut environment improves feed efficiency (FCR), contributing to stable feed costs.
- In the carcass, fuller loin eye and marbling (intramuscular fat) show favorable tendencies, leading to more consistent grading and stable yield.

“The sharp, eye-stinging odor when cleaning the drains is gone, making the work much easier.”
“The barn environment has settled down, and the pigs seem calmer and more energetic than before.”
“Overall management has become easier, and we can fatten the pigs more consistently.”

Yolk firm enough to lift with chopsticks
The “Bio Charger Egg” from Kudaka Poultry Farm comes from hens raised with Bio Charger A (feed). When cracked, the yolk is firm enough to be lifted with chopsticks. In our test placing it beside a well-known brand egg, the Bio Charger egg’s yolk stood up firmly and resisted breaking even when pinched with chopsticks.
The egg used in this test was a Bio Charger egg stored in the fridge for about 3 weeks after purchase. Even so, the yolk resisted breaking and kept enough firmness to be lifted with chopsticks.
When pinched with chopsticks, the yolk broke apart.
Even after 3 weeks, the yolk didn’t break and kept its shape when pinched with chopsticks.
Inquiries about pets and livestock are handled by our group company “Biotechno Ryukyu Co., Ltd.,” which has veterinarians on staff.
※ This is one example of a test we conducted. Yolk firmness and appearance vary with the egg’s freshness, storage and individual differences.
