SPECIAL STORY FEED & ADDITIVE MAGAZINE April 2023 69 are nutritive, functional and safe. Therefore, they fulfill the essential requirements when producers need to choose an ingredient to include in diets for cultivation animals. Moreover, the chicken hydrolysates are sustainable ingredients that decrease leftovers from animal slaughter, reducing wastes in the environment and cultivation tanks (in the aquaculture case), which also contribute to better water quality. As affirmed by Soares (2019) [2], to reuse raw materials from animal co-products is to consciously compensate for environmental impacts caused by the sector waste generation. The Chicken Protein Hydrolysates are produced by the enzymatic hydrolysis process that, with water utilization, breaks amino acid chains (that form the raw material proteins) and generate bioactive peptides - substances that provide several benefits for metabolism, health and animal performance, such as hypoallergenic, antimicrobial, antioxidant, antihypertensive and immunostimulant functionalities. The transformation of animal co-product raw materials into protein hydrolysates aims to achieve a functional and nutritional solution with low levels of minerals and fats (Pasupulek, et al., 2010) [3], rich in proteins and bioactive peptides that will aid with specific metabolic and nutritional needs. With the breaking of amino acids, the Chicken Protein Hydrolysates have a low molecular mass, in which 100% of the bioactive peptides are below 3,000 Da, a characteristic that makes this protein source an hypoallergenic ingredient, reducing probabilities of causing allergic reactions, a frequent problem in the pet food sector. It’s also worth noting the diversity of protein hydrolysates usages in nutrition. Besides the animal nutrition, hydrolysates can be used in food ingredients to enrich food in a process that allow the creation of rich and nutritive formulations, applicable in treatments for malnutrition and other diseases related to nutrient digestion and absorption, as well as for allergy control (Albuquerque, et al.) [4]. For all of these reasons, nutrient digestibility and absorption are some of the most important benefits provided by the Chicken Protein Hydrolysates in animal nutrition, which also present several other contributions, scientifically proven during tests conducted by companies that develop these ingredients and Universities from countries such as Brazil and Vietnam. APPLICATIONS AND BENEFITS IN ANIMAL NUTRITION Chicken hydrolysates have animal sources, such as chicken viscera, guts and meat that, after the enzymatic hydrolysis process, become functional and nutritional solutions for a large number of sectors within the animal nutrition industry, the latter being our main focus in this article. Chicken Protein Hydrolysates are formulated specially to enhance the performance of animal feeds, adding value to the species and cost-benefit to the producers. Besides improving digestibility and nutrient absorption, CPH has a protein rate of at least 75% in its composition.
