mg\/kg de ra\u00e7\u00e3o para\u00a0frangos de corte e galinhas poedeiras<\/strong>\u00a0e 7 mg\/kg de alimento para\u00a0patos e perus<\/strong>; correspondendo aos valores de orienta\u00e7\u00e3o de 5 mg\/kg de ra\u00e7\u00e3o para aves para DON na UE (2016\/1319\/EC)<\/p>\n

Informa\u00e7\u00f5es cient\u00edficas recentes indicavam que esses n\u00edveis deveriam ser mais baixos.<\/strong>\u00a0Assim, o Painel EFSA avaliou estudos publicados entre 31 de julho de 2016 e 19 de abril de 2022.<\/p>\n

V\u00e1rios estudos com\u00a0frangos de corte<\/strong>\u00a0mostraram que\u00a0o DON desencadeia uma diminui\u00e7\u00e3o da altura das vilosidades e danos intestinais em n\u00edveis t\u00e3o baixos quanto 1,9 mg\/kg ra\u00e7\u00e3o<\/strong>. Esses danos intestinais sendo considerados como adversos para a sa\u00fade animal, uma nova refer\u00eancia de 0,6 mg\/kg de ra\u00e7\u00e3o foi mantida, com base no valor de 1,9 ppm e aplicando um fator de incerteza (UF) de 3.<\/p>\n

Similarmente com\u00a0perus<\/strong>,\u00a0os efeitos adversos do DON no desempenho zoot\u00e9cnico e morfologia intestinal foram observados em n\u00edveis de 1,7 mg\/kg de ra\u00e7\u00e3o<\/strong>, diminuindo os valores de refer\u00eancia para 0,6 mg\/kg de ra\u00e7\u00e3o. Os valores de refer\u00eancias para\u00a0patos e galinhas poedeiras<\/strong>\u00a0permanecem inalterados, respectivamente 7 e 5 mg\/kg de ra\u00e7\u00e3o.<\/p>\n

O Painel tamb\u00e9m avaliou a exposi\u00e7\u00e3o de frangos e perus ao DON e a comparou com os valores de refer\u00eancia recentemente estabelecidos.<\/p>\n

Os resultados indicam que\u00a0o n\u00edvel m\u00e9dio de exposi\u00e7\u00e3o ao DON<\/strong>\u00a0e seus metab\u00f3litos \u00e9\u00a01,7 vezes maior<\/strong>\u00a0que os valores de refer\u00eancia para\u00a0frangos de corte<\/strong>, e\u00a02,5 vezes maior para perus de engorda<\/strong>\u00a0(ver Tabela\/ Imagem). Portanto,\u00a0deve-se ter cuidado especial para proteger frangos e peru dos efeitos adversos do DON e de seus metab\u00f3litos.<\/strong>[\/vc_column_text][image_with_animation image_url=”16688″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” constrain_group_1=”yes” alignment=”” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default” margin_top=”20″ margin_bottom=”20″][vc_column_text]Figura:<\/strong>\u00a0Compara\u00e7\u00e3o dos n\u00edveis estimados de exposi\u00e7\u00e3o DON e novos n\u00edveis de refer\u00eancia para aves.\u00a0Adaptado do EFSA Journal 2023;21(2):7806.<\/i>[\/vc_column_text][vc_column_text]Refer\u00eancia:<\/strong>\u00a0EFSA Panel CONTAM, 2023.
