“…These results indicate that ADL and AIA indigestible markers performed similarly to in vivo DMD in mimosa and bahiagrass in estimating forage DMD, but not in the concentrate, although AIA concentration in mimosa seemed to be low compared to others as recommended by Thonney et al [15]. Thonney et al [15] suggested that diets containing less than 0.75% AIA may produce under estimates of digestibility; average concentration of AIA for the diets used in the present study was similar or greater than 0.75% except mimosa diet (0.3%). Although concentration of AIA was low in mimosa browse, there was no significant difference between DMD coefficients (%) determined by the marker methods and by the in vivo DMD method in this study.…”

“…Consistent with the positive recovery of acid insoluble ash (AIA), organic matter digestibility (OMD) was greatly overestimated [14]. Thonney et al [15] suggested that diets containing less than 0.75% AIA may produce subjective estimates of digestibility. In contrast, Keulen and Young [16] reported that DMD estimates from AIA were not different from those measured by total fecal collection.…”

“…Os resultados de recuperação fecal de CIA e CIDA estão bastante próximos de 100%, enquanto a recuperação da lignina nas fezes foi abaixo de 90%. Para que a CIA possa ser usada com precisão para estimar a digestibilidade dos nutrientes em ruminantes, THONNEY et al (1984) recomendam que a ração ou o alimento contenha teor de 0,75% de CIA ou mais na matéria seca. Já para a CIDA, a porcentagem adequada deverá ser próximo Tabela 2 -Composição na dieta e porcentagem média de recuperação fecal da lignina, cinza insolúvel em HCl (CIA) e cinza insolúvel em detergente ácido (CIDA) para os cavalos alimentados com feno de capim coast-cross e feno de capim coast-cross mais capimelefante, com seus respectivos erros-padrão ADIA ou maior que 3% na ração, para evitar dificuldades na recuperação (Sherrod et al, 1978, citados por CARVA-LHO, 1989.…”

“…No entanto Sherrod et al (1978) citam que o uso da CIA somente será adequado, quando sua participação na matéria seca da ração for superior a 3%, em contraste com Thoney et al (1979), que encontraram semelhança entre o método da coleta total de fezes e seu valor estimado pela CIA, esta última variando de 0,33 a 0,74% da matéria seca da dieta. Thoney et al (1985) concluíram que, se a dieta apresentar 0,75% ou mais da CIA na matéria seca, seu uso é seguro.…”
