The sample size needed to determine DM is dependent on the drying equipment that will be used, and can range from around 100 to 500 g (approximately ¼ to 1 lb). To accurately determine the DM of a feed, the sample collected must be representative of the feed. However, there are also electronic methods that have been used to determine the moisture content of feeds. The most common way that moisture is determined is through the evaporation of water from the feed, leaving only the dry contents behind. Dry Matter Determinationĭetermination of DM is a relatively simple and quick process that can be easily done on a farming operation. Increases or decreases in feed DM content result in over or under feeding of nutrients. The DM of feeds that are co-products of manufacturing industries are affected by the manufacturing processes themselves and the processing to which they are subjected.ĭetermining the DM content of feed provides a measure of the amount of a particular feed that is required to supply a set amount of nutrients to the animal. However, weather and environmental conditions, such as humidity, rain and snow, all affect feed moisture content. In many cases, the timing and method of harvest is the largest contributing factor to the moisture content of the feed. Although animals do have a requirement for water, providing water through an actual water source, instead of through feed ingredients, is necessary.Ī variety of factors affect the moisture content of feeds. Knowing the moisture content of a feed ingredient is important because the moisture content affects the weight of the feed, but does not provide nutrient value to the animal.

The nutrients in feeds, required by the animal for maintenance, growth, pregnancy, and lactation, are part of the DM portion of the feed. Dry matter refers to material remaining after removal of water, and the moisture content reflects the amount of water present in the feed ingredient. In general terms, the weight of a specific feed ingredient comes from either the moisture in the feed or from the dry matter (DM) portion. Please check this link first if you are interested in organic or specialty dairy production Moisture and Dry Matter Changes in the weight of a feed due to changes in moisture alter the nutrient concentrations supplied to the animal if appropriate adjustments are not made to accurately reflect the actual nutrient concentration of the feed ingredient. Feeding individual feed ingredients according to weight is only accurate if the moisture content of the feed is the same as it was during the ration formulation period. Although nutrients in ration formations are often described in terms of a percentage, animals require actual amounts of nutrients.
