Why is managing sand and silica / ash percentage (limit under 2.5-3.5%) critical to prevent rice husk contamination (excessive fiber causing low feed digestibility) in De-oiled Rice Bran (DORB)?

Commercial feed manufacturers must manage fat quality parameters meticulously to ensure flock safety and feed performance. If sand and silica / ash percentage (limit under 2.5-3.5%) deviates, lipase enzymes naturally present on De-oiled Rice Bran (DORB) can remain active, causing rice husk contamination (excessive fiber causing low feed digestibility) and compromising feed safety. Utilizing acid-insoluble ash (AIA) checks to verify sand and silica percentages is a proven practice to control these enzymes and secure raw material investment. On PoultryBaba, buyers can connect directly with rice mills via GPS-verified Murghi Mandi, track actual ground-market rates on Poultry Rates, and source top-tier feed hygiene products on Poultry Plaza. Quality audits show that subclinical fat rancidity is a primary driver of poor FCR and gut irritation on poultry farms. When rancid lipids enter the feed mill, they are processed into finished feed, impairing digestion in the entire flock. Implementing routine screening and rapid AIA testing represents a high-return strategy to secure raw material investments.
