Why it's different

Not a generic licorice extract.

KANZOU® is made by Fabric Onishi Co., Ltd. of Fukuoka, Japan. Fabric Onishi offers four product forms for different feeding applications, with composition and use information documented in the manufacturer’s source materials.

What it is

Documented
100% licorice extract
A single plant input — Glycyrrhiza. Described in the source materials as a natural, plant-derived feed additive, not a synthetic compound.
Glycyrrhizic acid
A key naturally occurring constituent of licorice identified and discussed in the manufacturer and research materials.
Four product forms
Fabric Onishi provides Powder, Granule, Mitsu, and Homare for the feeding applications described in its product documentation.
Made in Japan
Raw material imported into Japan and processed in Japan; every lot tested before shipment.

How it is positioned

Conservative
A feed additive
Used inside an existing ration as a top-dress or mix-in — not a replacement for the ration, and not a veterinary medicine.
Evidence-led
Backed by a 2019 conference embryo study, collaborative calf data, and independent prefectural research — presented as documented findings, not guarantees.
Traceable supply
Raw material sourced outside China, with whole-chain traceability from field to finished extract.
Wide animal range
Dairy and beef cattle, calves, breeding stock, embryo-donor cows, and horses.

05 / Use cases

Review documented use cases.

The source materials describe KANZOU® in use across several livestock applications. The summaries below reflect those materials and cited studies; feeding figures are manufacturer or source references, not individualized recommendations.

Use case 01

For calf programs

Why buyers ask: for suckling and growing calves, buyers look at feed intake, body-weight gain (reported as trends), and a gut-microbiome evidence area. Mitsu dissolves into milk replacer through to weaning.

07 / Evidence

The evidence, kept separate and honest.

Evaluate the evidence separately from the commercial positioning. We distinguish KANZOU®-context research, independent third-party studies, and partner blended-product references, and preserve the limitations reported in the source materials, including where findings are trends rather than statistically significant. Full references are available on request.

Category 01

KANZOU® / Onishi-context research

International Embryo Technology Society Annual Meeting · New Orleans · 2019

Embryo production in Japanese Black donor cows.

Presented at the International Embryo Technology Society Annual Meeting (2019). In Japanese Black donor cows fed the licorice extract through a superovulation protocol, the study reported a significantly higher mean number of transferable embryos and a significantly higher mean embryo-quality score than control. Data from Good Embryo Technology / Zen-Noh ET; the mean number of total ova recovered did not differ significantly.

8.113.1 Mean transferable embryos per cow P<0.05
51.2%60.3% Normal / transferable embryo rate
4890 Donor cows (control vs supplemented)

Figures compare the 60–90 day supplementation group with control. The study found no significant difference in the mean number of ova/embryos recovered. Full reference available on request.

Collaborative · Rakuno Gakuen / CRC

Calf growth and intake.

In collaborative data (Rakuno Gakuen University, Dr. Osamu Dochi; CRC Cattle Research Center, Dr. Masateru Koiwa), calves fed KANZOU® tended toward higher body weight at transfer to the growing stage and steadier milk-replacer intake. The authors’ own “tended to” framing is preserved; results were trends, not statistically significant.

Mechanism · Dr. Koiwa

Liver-related research context.

Dr. Koiwa notes that breeding-driven gains in milk yield have outpaced cow body-size growth, raising the metabolic burden on the liver. In that frame, the source materials discuss licorice in relation to liver health. This is presented as research context, not as a disease-treatment or prevention claim.

Category 02

Independent third-party studies

Fukui Prefectural Livestock Experiment Station · 2nd–4th reports · latest: Bulletin No. 36 (2023)

A government-laboratory calf-study series.

Across three sequential reports (the latest in Bulletin No. 36, 2023), the Fukui Prefectural Livestock Experiment Station fed KANZOU® / KANZOU® Mitsu to suckling Japanese Black calves. Feed intake and body weight tended to be higher with licorice, and the immune-associated Bacteroides group increased — described consistently as trends rather than statistically significant results. No disease occurred in either group.

0.750.79 Body-weight gain, kg/day trend
≈3.3× observed Bacteroides change by 40 days (4th report) not statistically significant
3 Sequential independent reports

Independent prefectural research. Results are reported as trends; the studies note no statistically significant difference. The 4th report’s separate brewer’s-grains finding is a feeding-management result, not a KANZOU® claim.

08 / Why licorice

Why buyers ask about licorice extract.

The plant, a key naturally occurring constituent, and the areas explored in the cited research — presented with the same limitations and context as the source materials.

01 / The plant

Glycyrrhiza. Legume family. Central Asia.

Licorice raw material is sourced from Central Asia and the Eurasian continent — Tajikistan, Kazakhstan, Azerbaijan, and Russia — through the supply network described in Fabric Onishi’s source materials. Material is imported into Japan and processed there.

02 / Key constituent

Glycyrrhizic acid, a key constituent.

Glycyrrhizic acid is a naturally occurring constituent of licorice and is identified in Fabric Onishi’s documentation and the cited research. KANZOU® is described in the manufacturer materials as a licorice extract containing naturally occurring constituents including glycyrrhizic acid and flavonoids. Exact composition information for individual product forms is available in the source documentation.

09 / Sourcing

Quality, sourcing, and traceability.

Licorice raw material is sourced from Central Asia and the Eurasian continent — not from China — through a partner with joint-venture factories in those regions. It is imported into Japan, processed in Japan, and confirmation-tested per lot. Multi-region procurement is described as a way to keep supply continuous if any one region is disrupted.
