The first important component of the for¬age is the energy content. For lactating dairy cows, this is measured by evaluating the fiber con¬tent of the feed stuff. The energy content of the forage determines how productive the cow can be, if that would be the only thing she were fed. If a higher energy diet is desired, grains are usually added to the diet.
The second major component of feed is the protein. The crude protein is a measurement of the total amount of protein that is in the feed stuff. The crude protein content is analysed by measuring the nitrogen content of the feed stuff and multiplying the result by 6.25. There are also some measurements that show us the protein fractions, which are what make up the total protein. This is one way that the quality of the protein is expressed. Some of the frac¬tions are an expression of how quickly the protein is available for absorption by the animal. Other frac¬tions show us how much has been damaged by the storage process. There are also those that give us an expression of how much is available to be used by the animal.
The third major component of feed is the mineral content. The ratio of minerals gives us an¬other indication of quality pertaining to the protein, as well as the overall quality. These ratios also affect the digestibility of the fiber, thus improving the energy of the feed stuff. These ratios vary depending on the kind of feed stuff that the analysis is for.
