Antioxidants prevent fat oxidation during storage; antifungals (primarily propionic acid and formic acid) prevent mold and bacterial spoilage, especially in silage and high-moisture feeds.\n\n---\n\n## 1. Antioxidants (防氧化剤)\n\n**Designated substances:**\n- **エトキシキン** (Ethoxyquin)\n- **ジブチルヒドロキシトルエン** (Di-tert-butyl-4-hydroxytoluene, BHT)\n- **ブチルヒドロキシアニソール** (Butylated hydroxyanisole, BHA)\n\n**Maximum limit:**\n\n| Item | Limit |\n|---|---|\n| Combined total of all three active ingredients | **≤150 g per tonne of feed** |\n| Feedstock included | General feed (excluding intermediate materials) |\n| Labeling | Total content expressed as **percentage (%)** of combined active ingredients |\n\n> Legal basis (条項カ): 「カ エトキシキン、ジブチルヒドロキシトルエン及びブチルヒドロキシアニソールの飼料（飼料を製造するための原料又は材料を除く。）中の含有量は、それぞれの有効成分の合計量で**飼料１トン当たり150ｇ以下**でなければならない。」\n\n---\n\n## 2. Antifungals — Propionic Acid Group (プロيون酸類)\n\n| Substance | Feed type | Maximum limit |\n|---|---|---|\n| プロピオン酸 (Propionic acid) | General feed (excluding materials) | **≤0.3%** active acid |\n| プロピオン酸カルシウム (Calcium propionate) | Silage (サイレージ) | **≤1.0%** active acid |\n| プロピオン酸ナトリウム (Sodium propionate) | Silage (サイレージ) | ≤1.0% active acid |\n\n**サイレージ (Silage)** definition: Feed prepared by filling grass, etc. (including dried material with reduced moisture content) into a silo or suitable container and fermenting through lactic acid fermentation.\n\n> Legal basis (条項オ): 「オ プロピオン酸、プロピオン酸カルシウム及びプロيون酸ナトリウムの飼料中の含有量は、サイレージにあっては**プロيون酸として1.0％以下**、それ以外の飼料にあっては**プロيون酸として0.3％以下**でなければならない。」\n\n---\n\n## 3. Formic Acid (ギ酸)\n\n| Substance | Exclusions | Maximum limit |\n|---|---|---|\n| ギ酸 (Formic acid / methanoic acid) | Excludes calcium formate and potassium diformate bound forms | **≤0.5%** as formic acid |\n\n> Legal basis (条項エ): 「エ ギ酸（ギ酸力ルシウム及び二ギ酸カリウム中に含まれるものを除く。）の飼料（飼料を製造するための原料又は材料を除く。）中の含有量は、**ギ酸として0.5％以下**でなければならない。」\n\n---\n\n## Verification Claims (substring_match)\n\n| # | Claim | Source match |\n|---|---|---|\n| 1 | Antioxidant combined total limit: 150 g/tonne feed (エトキシキン + ジブチル + ブチル) | ✓ 条項カ |\n| 2 | Propionic acid general feed maximum: 0.3% | ✓ 条項オ |\n| 3 | Propionic acid silage maximum: 1.0% | ✓ 条項オ |\n| 4 | Formic acid maximum: 0.5%, excluding calcium/potassium formate bound forms | ✓ 条項エ |\n| 5 | Antioxidant content must be labeled as combined percentage of all three active ingredients | ✓ 条項7 |\n","sources":[],"tokens_estimated":580,"generated_at":null,"tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
