Efeito de fontes e níveis de selênio sobre parâmetros fisiológicos em frangos de corte

Abstract: RESUMOAvaliaram-se a retenção aparente, a deposição hepática, tecidual e plasmática, bem como a eficiência da glutationa peroxidase hepática e plasmática em frangos de corte alimentados com diferentes níveis e fontes de selênio. Utilizaram-se 300 pintos machos com 14 dias, submetidos a um esquema fatorial 3x3 + 1 (três níveis de Se − 0,150; 0,300; 0,450ppm, e três fontes comerciais de Se -uma inorgânica e duas orgânicas + um tratamento controle sem suplementação), em DIC. Do primeiro ao 14 o dia de idade − per… Show more

“…According to Navarro-Alarcón & López-Martínez (2000), organic Se in the form of selenomethionine and selenocysteine replaces sulfur in analogous molecules of methionine and cysteine, being absorbed through the sites of amino acid absorption, with an optimized deposition in the animal's body when compared with inorganic Se. These results are in alignment with those obtained in other works (Payne & Southern, 2005;Gomes et al, 2011;Boiago et al, 2014;Oliveira et al, 2014;Rajashree et al, 2014;Silva et al, 2019aSilva et al, , 2019b. Similar results were also found by Gomes et al (2011), who compared two sources of Se-yeast (2,000 and 1,000 ppm) with sodium selenite.…”

Similar results were also found by Gomes et al (2011), who compared two sources of Se-yeast (2,000 and 1,000 ppm) with sodium selenite. These authors concluded that the organic source, regardless of the Se concentration, provided a greater deposition of Se in the muscle.…”

“…Este tipo de suplementação é muito utilizada para suprir as necessidades nutricionais das aves, porém, o uso indiscriminado pode acarretar em alterações metabólicas. Com isto, no ano de 2000, a Food and Drug Administration (FDA), liberou o uso na forma orgânica, esta testada para avaliações importantes na produção de aves(Gomes et al, 2011). Dietas comerciais necessitam de suplementação de Se devido a variação da concentração encontrada nos alimentos e no solo.…”
