  • Determining Forage Quality: Understanding Feed Analysis

    Moisture or dry matter content of a feed is determined by heating a weighed sample of feed in a convection drying oven until a constant weight is reached (2448 hours). Dry weight is expressed as a ratio to original sample weight (moisture + DM) or converted to a percent. For example, a feed sample weighs 150 g wet and 50 g dry.
