De-Oiled Rice Bran (DORB) is a byproduct obtained after extracting oil from rice bran, which itself comes from the rice milling process when brown rice is polished into white rice. DORB retains the nutrient-rich outer layers of the rice grain (pericarp, aleurone, and some germ and endosperm) but has a significantly reduced fat content compared to full-fat rice bran. High in protein, fiber, and minerals, DORB is a cost-effective and widely used ingredient in poultry and cattle feed, offering excellent stability without the rancidity concerns of full-fat rice bran.

De-Oiled Rice Bran Technical Specification

Below is a technical specification for DORB, focusing on its nutritional composition and physical characteristics relevant to poultry and cattle feed. Values may vary slightly based on processing methods, so confirm specifics with Ametheus.

Physical Characteristics

  • Appearance: Fine, light brown to tan powder
  • Moisture Content: 8–12% (ensures storage stability)
  • Oil Content: 2–5% (post-extraction residual fat)
  • Ash Content: 10–18% (indicates mineral richness)
  • Particle Size: Typically 0.5–2 mm (depends on milling and extraction process)

Nutritional Composition (Approximate Values, Dry Matter Basis)

  • Crude Protein: 14–18% (supports growth and milk production)
  • Crude Fat: 2–5% (low-fat energy source)
  • Crude Fiber: 10–16% (aids digestion, higher than full-fat rice bran)
  • Digestible Carbohydrates: 35–45% (primary energy source)
  • Neutral Detergent Fiber (NDF): 25–35% (key for ruminant digestion)
  • Acid Detergent Fiber (ADF): 12–18% (indicates digestibility)
  • Phosphorus: 1.2–1.8% (phytate-bound, benefits from phytase in monogastrics)
  • Calcium: 0.1–0.3% (low, may require supplementation)
  • Energy (Metabolizable Energy, ME):
    • Poultry: 2,200–2,600 kcal/kg
    • Cattle: 2,500–2,900 kcal/kg
  • Vitamins: Rich in B vitamins (e.g., thiamine, niacin)
  • Antioxidants: Trace amounts of gamma-oryzanol and tocopherols (reduced post-extraction)

Anti-Nutritional Factors

  • Phytic Acid: 4–6% (binds minerals, reducible with phytase)
  • Trypsin Inhibitors: Minimal amounts (affects poultry protein digestion slightly)

Storage and Shelf Life

  • Shelf Life: Up to 12–18 months (stable due to low oil content, no stabilization needed)

Detailed Data for Poultry & Cattle Feed Farms

Here’s how DORB benefits poultry and cattle feed farms, with practical insights to choose Ametheus as your supplier:

For Poultry Feed

  1. Nutritional Benefits:
    • Protein (14–18%): Supports broiler growth and layer egg production.
    • Low Fat (2–5%): Reduces energy density, ideal for balanced diets.
    • Fiber (10–16%): Promotes gut health, though high levels may limit inclusion.
    • B Vitamins: Enhances metabolism and feather condition.
  2. Recommended Inclusion Rates:
    • Broilers: 15–25% (higher with phytase or xylanase enzymes).
    • Layers: 10–20% (maintains egg quality without excess fat).
    • Excess (>25%) may reduce feed efficiency due to higher fiber.
  3. Processing Tips:
    • Pair with phytase to improve phosphorus availability (only ~15% naturally digestible).
    • Combine with energy-rich ingredients (e.g., corn) to offset lower fat content.
  4. Cost Efficiency:
    • A budget-friendly alternative to soybean meal or wheat bran, reducing overall feed costs.
  5. Challenges:
    • Higher fiber may lower digestibility in monogastrics.
    • Low fat content requires balancing with other energy sources.

For Cattle Feed

  1. Nutritional Benefits:
    • Energy (2,500–2,900 kcal/kg ME): Suitable for maintenance and moderate production.
    • Protein (14–18%): Complements forage-based diets for growth and lactation.
    • Fiber (NDF 25–35%): Enhances rumen fermentation and digestion.
    • Low Fat (2–5%): Prevents excessive fat intake in high-producing cows.
  2. Recommended Inclusion Rates:
    • Dairy Cows: 20–40% (boosts milk yield without fat overload).
    • Beef Cattle: 25–50% (replaces other fibrous feeds like wheat bran).
    • Higher inclusion possible due to low fat and stable nature.
  3. Processing Tips:
    • Acts as a carrier for supplements in pelleted feeds.
    • Ideal for dry season feeding when forage quality drops.
  4. Cost Efficiency:
    • Abundant supply (derived from rice bran’s global 70 million metric tons) ensures affordability.
    • Locally sourced, minimizing transport costs compared to imported feeds.
  5. Challenges:
    • Low calcium requires supplementation.
    • Monitor silica content (from hull contamination) to avoid digestive issues.
