De Oiled Rice Bran (DORB) is a by-product of rice processing that is commonly used as a feed ingredient for poultry. Here are some key nutrition facts about DORB as poultry feed:
- Protein content: DORB is a low-protein feed ingredient, with a typical protein content of around 10-12% on a dry matter basis. This means it is not a significant source of protein for poultry.
- Amino acid profile: The protein in DORB is relatively low in lysine and methionine, which are essential amino acids for poultry. This means it must be supplemented with other feed ingredients to provide a well-balanced amino acid profile.
- Energy content: DORB is a moderate source of energy for poultry, with a typical metabolizable energy content of around 2,800-3,200 kcal/kg on a dry matter basis.
- Fiber content: DORB is high in fiber, with a typical crude fiber content of around 15-20% on a dry matter basis. This means it can contribute significantly to the bulk of poultry feed and may have a laxative effect if fed at high levels.
- Mineral content: DORB is a good source of several important minerals, including phosphorus, potassium, and magnesium. However, it is relatively low in calcium, which is an important nutrient for poultry eggshell formation.
Overall, DORB is a low-quality feed ingredient for poultry, with a low protein content and a high fiber content. It can be used as a source of energy in poultry diets, but should be supplemented with other feed ingredients to provide a well-balanced amino acid profile. It is also important to ensure that DORB is free from contaminants, such as mycotoxins, which can be harmful to poultry.
