“…The FP values using CO, LIPE ® , NANOLIPE ® , and INDF were similar (p>0.05) to those using TC (Table 3), which is used to validate the use of these indicators (OLIVEIRA et al, 1997). However, TD and IADF underestimated FP (p<0.05) whereas IDM overestimated FP relative to TC.…”

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.

ResumoA quantidade de alimento ingerido por um animal e o quanto ele absorve de nutrientes é essencial para que se façam alterações a respeito do alimento e da resposta do animal, assim o uso de indicadores é uma das ferramentas que facilita avaliar determinados parâmetros fisiológicos e nutricionais. Os indicadores são divididos em dois grandes grupos, internos e externos, os mesmos podem ser adicionados à dieta ou fornecidos via oral ou ruminal aos animais. Para que uma substância possa ser utilizada como indicador, deve atender a determinados critérios. Os indicadores são substâncias capazes de colaborar com inúmeros aspectos nas áreas da alimentação e da nutrição animal, principalmente em situações a pasto. Logo, para o uso dos mais diversos indicadores existentes que são utilizados para estimar taxas de passagem, consumo, produção fecal e de digestibilidade, devem ser estabelecidos critérios, como facilidade de uso e determinação, que norteiem a

“…N-alkanes have been commonly used in nutritional studies with the purpose of estimating intake, digestibility and botanical and/or morphological composition of the forage consumed by domestic ruminants. For tropical and sub-tropical forage species this technique has been adopted quite regularly (Oliveira & Prates, 2000;Oliveira et al, 2007) and methodology for extraction and determination adequately adapted (Oliveira, 2004). However, information is needed regarding the use of these markers for evaluating feeding strategies as well as management of wild ruminant and non-ruminant animals, either in conservationist farms or captivity.…”

Knowledge of information relative to the digestibility, intake and botanical and morphological composition of the diet is important in nutritional studies, since it provides the basis for understanding aspects related to the ingestive behavior and selectivity of animals. N-alkanes have been used successfully as markers in studies with many species of animals, particularly domesticated ruminants, most of the times as replacements for conventional markers as chromium oxide for example. However, for wild ruminants and non-ruminant animals information on this technique is still scarce and, as a consequence, its potential for use unknown. This review reports the use of this technique in studies of feed digestibility, intake and diet composition with wild ruminants and non-ruminant animals, summarizing results and inferring on the feasibility and applicability of the technique.
