Rice bran is used in animal feed formulations and feed blending.
Rice bran, a nutrient-dense byproduct of rice milling rich in fat and fiber, is a widely used, cost-effective ingredient in livestock feed. It enhances energy supply in cattle, poultry, and swine diets, improving feed efficiency and palatability. Key considerations include proper stabilization to prevent rancidity and limiting inclusion rates in poultry.
Key Aspects of Rice Bran in Animal Feed
Nutritional Value: Contains high levels of fat (energy source), protein, and essential minerals such as phosphorus and calcium, which are crucial for livestock health.
Applications: Commonly used in feed for dairy and beef cattle (improved milk/meat production), pigs, and poultry (improved egg quality/growth).
Benefits: It serves as a cost-effective, high-energy alternative to other cereals in feed formulations.
Feed Formulation Considerations:
Stabilization: Raw rice bran contains lipase, which causes rapid oxidation (rancidity); thus, it must be stabilized or used fresh.
Inclusion Rates: While it can be a significant part of ruminant diets, inclusion in poultry diets is generally limited.
Formulation: It is used in, raw, dried, or fermented forms to enhance nutrient digestibility and improve animal performance.
Fermented rice bran is becoming increasingly popular to enhance nutritional value and reduce antinutritional factors.
