Answer
To measure the dry matter content of a named animal feed, such as alfalfa hay, one can use the following steps: 1. Weigh a suitable container and record its mass. 2. Place a known amount of the alfalfa hay into the container and weigh it again. 3. Dry the feed in an oven at a specified temperature until all moisture is removed. 4. Weigh the container with the dried feed and record this mass. 5. Calculate the dry matter content by subtracting the initial mass of the container from the final mass and dividing by the initial mass of the feed, then multiplying by 100 to obtain a percentage.
