SUMMARY:

The energy level in the diet limits the consumption of feed by the birds, so the other nutrients in the diet, such as proteins, vitamins, minerals and lipids, must be adjusted in accordance with the energy level of the feed, with the aim of favoring the fulfillment of nutritional requirements of laying hens as a whole. For birds, the metabolizable energy (ME) content, also called apparent metabolizable energy (AME), is used to formulate diets, since this measure corresponds to the value of energy readily available to metabolic processes, as it represents the difference between gross energy from food and energy losses from faeces and urine. Thus, it is necessary to analyze the energy, amino acid and mineral density of laying hens in relation to productive performance and egg quality, given that the nutritional requirements of ME, amino acids and minerals of the birds vary with the lineage, age, environment and ways of processing the feed. Studies show that the energy increase reduces feed intake, as well as promotes increases in egg weight, yolk, albumen and egg mass. These variables are directly affected by the age of the laying hens, since the use of carbohydrates, amino acids and minerals that make up the diet depend on the stage of development of the gastrointestinal tract and the growth of the birds. Thus, the levels of ME, amino acids and minerals present in the diet directly interfere with the productive characteristics of laying hens and the quality of the egg and, therefore, the shelf life of the egg.
