Question

Pull on your rubber boots and get up early you are the proud manager of a dairy farm. when shopping for alfalfa hay you find two possible sources close by and take samples from both. a sample from stark county weighed 5.1 g before drying and 4.7 g after drying. A sample from dub country weighed 5.5 before going into the microwave and 4.89 g after drying to a constant weight. what is the DM content of both hays? how many pounds of dry hay do you buy when you purhcase a ton of hay from each source if you purchased each on an as fed basis?

Explanation / Answer

Sample from Stark County

DM Content = (4.7/5.1) × 100 = 92.157%

Sample from dub county

DM Content = (4.89/5.5) × 100 = 88.909%

If 1000 kg is purchased from each of the sources then we calculate by evaluating the percentage.

From Stark County => 92.157% of 1000 kg = 921.57 kg

From Dub County => 88.909% of 1000 kg = 889.09 kg
