Why does a deviation in sand and silica / ash percentage (limit under 2.5-3.5%) lead to rice husk contamination (excessive fiber causing low feed digestibility) in Stabilized Rice Polish?

Fungal colonization and enzyme reactivation in stored feed ingredients represent major risk factors for commercial poultry feed mills. Suboptimal sand and silica / ash percentage (limit under 2.5-3.5%) leads to localized heating and lipid degradation, creating a breeding ground for pathogens that trigger rice husk contamination (excessive fiber causing low feed digestibility). Implementing acid-insoluble ash (AIA) checks to verify sand and silica percentages is necessary to keep the bulk meal dry and maintain stable fat quality. To secure top prices for premium rice polish lots, sellers rely on PoultryBaba's GPS-verified Murghi Mandi to connect with direct buyers, check city-wise rates on Poultry Rates, and source aeration equipment on Poultry Plaza. Warm air rising through the bulk grain mass carries moisture upward, which condenses on the cold upper layers of the silo. This moisture migration creates a highly favorable zone for mold growth and toxin production. Continuous aeration and quality tracking are critical to prevent this localized degradation.
