Estimativa da digestibilidade aparente da matéria seca por meio de indicadores internos em eqüinos

Abstract: RESUMO -Com o objetivo de comparar metodologias de estimativa do coeficiente de digestibilidade da MS (CDMS) em dietas para eqüinos, avaliaram-se o método de coleta total de fezes (CT) e o uso dos indicadores internos celulose indigestível (CELi), fibra em detergente ácido indigestível (FDAi) e cinza insolúvel em ácido (CIA). No ensaio de digestão, foram utilizadas 16 éguas adultas da raça Mangalarga Marchador, entre 3,5 a 18,4 anos de idade e 394,80 ± 46,22 kg. As dietas, isoprotéicas e isocalóricas, foram co… Show more

“…Oliveira et al (2003) verified positive recuperation rates 118.37 and 122.88% for FDNi and FDAi, respectively, obtained by in vitro incubation with rumen liquid in horses fed on mixed diet, in the proportion 60:40 of roughage:concentrate. Conversely, Stein et al (2006) evaluated FDAi, CELi and lignin as markers in the diet of mares fed on a mixed diet and obtained a 100% fecal recuperation (p < 0.05) for FDAi. This fact confirms rates in current research.…”

“…After drying, the samples were once more weighed and ground in a 1 mm mesh sieve. Bromatological analyses (DM, OM and CP) for hay, corn and feces were undertaken according to methodology by Silva (1989), and for cell wall components (FDN and FDA), according to Van Soest et al (1991), at the Animal Nutrition Laboratory of the Faculty of Veterinary Medicine and Animal Sciences, Unesp, Campus of Botucatu, São Paulo State, Brazil. Starch rates were determined following Macrae and Armstrong (1968) at the Bromatology Lab of the Department of Animal Sciences of Esalq-USP, Brazil.…”

“…Algumas evidências demostram que é possível a utilização desses compostos para obtenção da digestibilidade de nutrientes, já que os resultados apontam altas taxas de recuperação (TR) fecal (Stein et al, 2006).…”

“…Indicadores têm sido utilizados em muitos estudos para avaliação da digestibilidade em equinos (SALIBA et al, 2002;SILVA et al, 2006;STEIN et al, 2006;SIQUEIRA et al, 2009;GOBESSO et al, 2011). Entretanto, nenhuma substância reúne todas as características necessárias para ser considerada um indicador perfeito.…”
