A nutritionally balanced diet is crucial for the welfare of animals. As a matter of fact, an animal's nutritional status influences its ability to reach its potential for growth, reproduction, and longevity. Furthermore, it is important for the quality of livestock products such as milk, meat, and eggs, which contribute to human nutrition.
Feed is made up of many ingredients, which are fats, oils, carbohydrates, protein, vitamins, minerals. Typically, cereals such as wheat or barley provide energy while soybeans, lupins, and peas provide protein. In order to develop a nutritionally balanced diet, it is important to know in which amount these elements should be included both in the diet and in every single component of the feed, as for instance, peas.
