Resumo: Broiler`s diets are mainly composed of plant origin products, where most of the phosphorus (P) is in the unavailable form, called phytate. The phytate molecule and the nutrients attached to it cannot be absorbed in the digestive tract without enzymatic degradation by the phytases. Phytases hydrolyze phytate in one molecule of inositol and six inorganic phosphate molecules reducing their antinutritional effects. The magnitude of phytase response may be more significant with increasing inclusion levels and phytate degradation correlates with large increases in P retention, tibia ash concentration, weight gain, feed intake, feed efficiency, retention of nitrogen, apparent metabolizable energy and Ca retention. Therefore, this review has the objective of to characterize phytase and to address aspects related to its efficacy and its extra phosphoric effects in diets for broilers.

A molécula de fitato e os nutrientes ligados a ela não podem ser absorvidos no trato digestivo sem degradação enzimática realizada pelas fitases. As fitases hidrolisam o fitato em uma molécula de inositol e seis moléculas inorgânicas de fosfato reduzindo os seus efeitos antinutricionais. A magnitude da resposta da fitase pode ser mais significativa com o aumento dos níveis de inclusão e a degradação do fitato se correlaciona com grandes aumentos na retenção de P, concentração de cinzas na tíbia, ganho de peso, consumo de ração, eficiência alimentar, retenção de nitrogênio, energia metabolizável aparente e retenção de Ca. Por isso, esta revisão tem o objetivo de caracterizar a fitase e abordar os aspectos relacionados na sua eficácia e seus efeitos extra fosfóricos em dietas para frangos de corte.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/49110.52945/rac.v33i1.491Agropecuária Catarinense Journal; Vol. 33 No. 1 (2020); 68-72Agropecuária Catarinense; v. 33 n. 1 (2020); 68-722525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/491/708https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBroch, JomaraSangalli, Gabriela GlaserSavaris, Vaneila Daniele LenhardtNunes, Ricardo Vianna2021-06-01T16:36:59Zoai:ojs.publicacoes.epagri.sc.gov.br:article/491Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-06-01T16:36:59Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
