Resumo: Fecal production and apparent dry matter digestibility (ADMD) were evaluated using external markers (chromium oxide; titanium dioxide; isolated, purified, and enriched lignin (LIPE®); and isolated, purified, and enriched lignin nanoparticles (NANOLIPE®) and internal markers (indigestible DM (IDM), indigestible neutral detergent fiber (INDF), and indigestible acid detergent fiber (IADF) in diets based on Tifton 85 bermuda grass (Cynodon sp.) hay containing different concentrations of a cocoa by-product. Sixteen crossbred (Holstein × Zebu) dairy heifers with a mean live weight of 363.00 ± 27.70 kg were evaluated and distributed in a completely randomized block design with a split-plot arrangement. The plots corresponded to the diets, which differed in the substitution of bermuda grass hay with different concentrations (0, 8, 16, and 24% of DM) of the cocoa by-product, whereas the splitplots represented the indigestible markers. Chromic oxide, LIPE®, NANOLIPE®, and INDF accurately estimated ADMD and fecal production whereas titanium dioxide, IDM, and IADF did not accurately estimate these parameters.

Foram utilizadas dezesseis novilhas leiteiras mestiças Holandês X Zebu, peso vivo médio (363,00 ± 27,70 kg), distribuídas em delineamento inteiramente casualizado com arranjo em parcelas subdivididas. As dietas oferecidas foram as parcelas, que se diferenciavam quanto à substituição do feno de capim Tifton 85 (Cynodon sp) pelo coproduto do cacau em diferentes níveis (0, 8, 16 e 24% da MS) e, os indicadores, as subparcelas. Os indicadores óxido crômico, LIPE®, NANOLIPE® e FDNi estimaram com acurácia e precisão a digestibilidade aparente dos nutrientes e a produção fecal. Os indicadores dióxido de titânio, MSi e a FDAi foram ineficientes para estimar esses parâmetros.UEL2019-08-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3488510.5433/1679-0359.2019v40n6p2771Semina: Ciências Agrárias; Vol. 40 No. 6 (2019); 2771-2782Semina: Ciências Agrárias; v. 40 n. 6 (2019); 2771-27821679-03591676-546Xreponame:Semina.
