Feeding De-Oiled Rice Bran to Fishes: Improving Growth and Digestibility

Introduction

The aquaculture industry is continuously seeking innovative and cost-effective alternatives to traditional fish feed ingredients. One such alternative that has gained attention in recent years is the use of de-oiled rice bran (DORB) as a primary ingredient in fish feeds. When properly processed and sourced, DORB can contribute to improved growth rates, enhanced digestibility, reduced disease incidence, and increased weight at harvest time. This article will explore the benefits of feeding DORB to fish, as well as the importance of selecting the right supplier for this essential ingredient.


Benefits of De-Oiled Rice Bran as Fish Feed Improved growth and digestibility

De-oiled rice bran is an excellent source of protein, fiber, and essential nutrients, making it a valuable addition to fish feed formulations. The high protein content promotes growth and muscle development in fish, while the fiber aids in digestion and nutrient absorption. Additionally, the presence of essential fatty acids, vitamins, and minerals helps maintain overall fish health and vitality.

Lower disease incidence
Feeding DORB to fish can help reduce the incidence of disease in aquaculture operations. The high levels of antioxidants and other bioactive compounds present in DORB can boost the immune system of fish, making them more resistant to infections and diseases. This is particularly important in high-density fish farming systems, where disease outbreaks can quickly devastate a population.

Increased weight at harvest
As a result of the improved growth and health of fish fed DORB, these fish often have a higher weight at harvest compared to those fed traditional feeds. This can lead to greater yields for aquaculture operations and increased profitability for fish farmers.


Selecting the Right Supplier

To fully capitalize on the benefits of feeding DORB to fish, it is crucial to select the right supplier. 

Here are some key factors to consider when choosing a DORB supplier:

Quality of the product
The quality of the DORB used in fish feed is critical to its effectiveness. Ensure that the supplier provides a consistent, high-quality product with the appropriate nutrient profile, free from contaminants, and with low residual oil content.

Processing methods
The way DORB is processed can significantly impact its nutritional value and digestibility. Look for suppliers that use modern, efficient processing methods to remove the oil from the rice bran, ensuring that the DORB retains its nutritional properties.

Sustainability and traceability
Choose a supplier that prioritizes sustainability and traceability in their operations. This will help ensure that the DORB is sourced from environmentally responsible practices and that the product can be traced back to its origin, providing assurance about its quality and safety.

Customer support and technical expertise
A good supplier should provide excellent customer support and possess the technical expertise to assist with any questions or concerns regarding the use of DORB in fish feed formulations. This can be particularly important when transitioning from traditional feed ingredients to DORB.


Conclusion

De-oiled rice bran offers numerous benefits for fish growth, health, and profitability in aquaculture operations. By choosing the right supplier and incorporating DORB into feed formulations, fish farmers can reap the rewards of this cost-effective, sustainable, and nutritionally rich ingredient.

Demystifying De Oiled Rice Bran (DORB): Quality Over Price

In the realm of animal feed and nutrition, De Oiled Rice Bran (DORB) stands out as a crucial ingredient known for its nutritional benefits. However, amidst the plethora of options available in the market, it's imperative to discern the varying qualities of DORB to ensure optimal results for livestock and derived products. Quality Disparities in DORB: DORB comes in different qualities, dictated by the standards of production and the quality of inputs used. While some manufacturers prioritize quality and adhere to stringent standards, others resort to cost-cutting measures, compromising on the product's integrity. Beware of Adulteration: Unfortunately, some unscrupulous entities resort to adulteration to reduce costs and attract price-sensitive customers. This compromises not only the nutritional value but also poses potential risks to livestock health. Prioritize Quality Over Price: When purchasing DORB, it's crucial to prioritize quality over price. While cheaper options ma...

Historical 2025 discussion — Impact of India’s DORB Export Ban on Vietnam: Current Realities and Future Market Dynamics

Historical article — originally published 23/04/2025. Policy dates, prices and market statements below describe the original 2025 context, not current export guidance or a current quotation. Check the applicable latest official DGFT notifications before an export decision. India’s decision to ban the export of de-oiled rice bran (DORB) in July 2023 marked a watershed moment for Vietnam’s animal feed industry. As the ban—now extended until September 30, 2025—continues, it has triggered immediate supply shocks, forced strategic realignments, and is set to reshape the future of feed ingredient sourcing in Vietnam. Significant Pre-Ban Reliance Before the ban, Vietnam was India’s largest DORB customer, accounting for over half of India’s total DORB exports in early 2023. In the first five months of 2023 alone, Vietnam imported 155,900 tons of Indian DORB, representing a staggering 54% of India’s total DORB exports .  This heavy reliance made Vietnam particularly vulnerable to any disru...

Historical 2025 analysis — Government Export Ban on De-oiled Rice Bran (DORB): Policy, Market Impact, and Future Outlook

Historical article — originally published 20 April 2025. Policy dates, prices and market statements below describe the 2025 context and are not current export guidance or a current price quotation. Check the latest DGFT notifications before an export decision. De-oiled Rice Bran (DORB) is an essential, yet often overlooked, component of India’s animal feed industry. Its rich profile of protein, fiber, and energy makes it invaluable for cattle, poultry, and aquaculture feed formulations. However, the Indian DORB market experienced a dramatic shift following a major government policy change in July 2023—a move whose reverberations continue to impact the entire sector. Backdrop: DORB and Its Role in Indian Animal Feed India is a global heavyweight in rice production, yielding approximately 5.5 million tonnes of DORB annually as a byproduct of the oil extraction process. Of this, about 10-12% was traditionally exported, with Vietnam being a top destination. DORB had solidified its place as...
