“…Our results are in agreement with study of Fru-Nji et al (2011) and more, had the same growth performance results as chickens fed Standard CP diets. Freitas et al (2011) used the same protease as previous researchers and confirmed improvement of FCR and digestibility of ME and CP, but no improvement in weight gain. Addition of protease from Aspergillus niger improved feed intake and weight gain in stud of Ghazi et al (2003) and Ghazi et al (2002).…”

“…Exogenous enzymes decrease the detrimental effects of nonstarch polysaccharides and enhance the digestion of nutrients in poultry diets (25). The enzyme increased the degree of protein hydrolysis and thereby increased the proportion of soluble low-molecular-size proteins, hence making the protein more available for uptake by the chickens (26).…”

“…Estudos têm descrito que as proteases endógenas sintetizadas e liberadas no trato gastrointestinal podem ser suficientes para aumentar a utilização da proteína da ração (Freitas et al, 2011). Rodrigues et al (2012), concluíram, que avaliando a digestibilidade da proteína bruta e aminoácidos das dietas das aves, que uma quantidade considerável de proteína passa pelo trato gastrointestinal sem ser completamente digerida.…”

RESUMO.O crescimento contínuo da indústria de alimentos resulta em uma grande quantidade de resíduos provindos dos frigoríficos de abate animais. O processamento dessa carne resulta em uma enorme quantidade de resíduos. A quantidade de resíduos produzidos além de ser uma grande perda de coprodutos com amplo potencial para reuso na cadeia produtiva, também causam sérios problemas de gestão, tanto do ponto de vista econômico como ambiental. Um dos resíduos gerados são as farinhas de origem animal (FOA), ingrediente rico em proteína, minerais e fonte energia em para rações de animais monogástricos. O uso de enzimas se torna uma estratégia interessante, pois podem tornar as FOA em ingrediente de maior valor nutricional. A suplementação enzimática beneficia a digestão e a absorção dos ingredientes, e sua adição em farinhas de origem animal pode melhorar a qualidade nutricional das rações e, consequentemente, o desempenho dos frangos. Esta revisão apresenta uma discussão sobre as enzimas uteis para nutrição de animais, principalmente as proteases utilizadas na hidrolise de resíduos proteicos, como as FOA. Palavras-chave: alimentos, avicultura, enzimas, nutriçãoUse of enzymes to increase the nutritional quality of animal meal for feed production.ABSTRACT. The continued growth of the food industry results in a large amount of animal slaughterhouse waste. The processing of this meat results in a huge amount of coproduct. The large amount of waste produced besides being a great loss of material with great potential for reuse in the productive chain, also causes serious management problems, both economic and environmental. One of the residues generated is animal meal (FOA), an ingredient rich in proteins, minerals and energy source in rations of monogastric animals. The use of enzymes becomes an interesting strategy because they can make FOA an ingredient of greater nutritional value. Enzyme supplementation benefits the digestion and absorption of the ingredients, and their addition in animal meal can improve the nutritional quality of the rations and, consequently, the performance of the chickens. This review presents a discussion on enzymes useful for animal nutrition, especially the proteases used in the hydrolysis of protein residues, such as FOA.
