Composição aminoacídica e digestibilidade ileal de aminoácidos de alimentos energéticos determinados com suínos submetidos à anastomose ileo-retal

Abstract: Com o objetivo de determinar os coeficientes de digestibilidade ileal aparente (CDA) dos aminoácidos de alimentos energéticos foi realizado um ensaio de metabolismo com suínos machos castrados submetidos à anastomose íleo-retal com isolamento do intestino grosso, utilizando-se o método da coleta total de excretas e três repetições por alimento avaliado. Os animais cujo peso médio inicial foi de 35,1kg foram alojados em gaiolas de metabolismo sendo um animal por unidade experimental. Os alimentos avaliados (mil… Show more

“…The amino acid composition of the three corns, the apparent digestibility coefficients (ADC), the true digestibility coefficients (TDC) and the true digestible amino acids (Tables 6 and 7) had similar values when compared to those presented by Rostagno et al (2005) for corn, high-lysine corn and high-oil corn, as well as when compared to those listed by Fontes et al (2007) for common corn and high-protein corn. ------------------------------------------- -----------------------------------------Aspartic -------------------------------------------------Essential amino acids (EAA) -------------------------------------- ------------------------------------------- -------------------------------------- It is important to consider the variation in the digestibility of amino acids within each type of corn.…”

“…Sauer and Ozimek (1986) reported that the digestibility of lysine ranges from 71% to 82% in corn common. A large part of this variation may be related to the relatively low content of amino acids in the cereal grains (Fontes et al, 2007). Small changes in the levels of endogenous amino acids could explain large variations in the values of apparent digestibility of amino acids, since this is expressed as percentages, especially for those amino acids which occur in small levels in grains such as lysine and tryptophan and to those which are found in relatively high concentrations in the endogenous secretions such as threonine, glycine and proline.…”

“…A composição encontrada no presente estudo se assemelha aos valores reportados por Rostagno et al (2005) e Gomes et al (2010). No entanto, Fontes et al (2007) obtiveram valores inferiores aos encontrados neste trabalho para arginina, isoleucina, metionina, ácido glutâmico, glicina e serina, enquanto que a lisina foi superior, e os demais aminoácidos foram semelhantes. Os cultivares estudados que apresentaram os maiores teores de proteína bruta (1, 3, 4 e 6) foram os responsáveis pelos maiores valores de aminoácidos essenciais (lisina, metionina e treonina).…”
