Abstract: NANOLIPE® is the LIPE®digestibility indicator incorporating nano particles that blend more smoothly and quickly in digesta, allowing reduction of the induction period, and higher recovery rates that compared with other indicators used in horses. The objective of this work was to compare the digestibility of the diet of nutrients in horses obtained by standard method (total collection of feces - TCF) and estimated by two internal indicators ( Klason Lignin - KL and indigestible Acid Detergent Fiber.- iADF) ) and external indicator NANOLIPE®, aiming to validate the latter for use in equine nutrition. In a randomized block design, eight Mangalarga Marchador adult mares were used to evaluate treatments (CBC, iADF, LK, NANOLIPE®). The diet was composed of 1.5% PV hay Coast Cross, 1.0% PV ofcommercial concentrate, divided into two daily treatment.. The trial lasted 13 days, with 8 adaptation to the diet and the handling and 5 for the experimental procedures. In the first five days of the experimental period total feces was collected and in the 3th and 4th day the animals received NANOLIPE® administered once a day through capsules of 0.25 g / animal / day orally. Using the method of TFC as standart, the Klason Lignin and iADF proved inadequate (P<0,05) and NANOLIPE® was considered efficient (P>0,05) for estimating the digestibility of nutrients in the equine species. There were differences (P <0.05) between fecal production values estimated by iADF (0.86 kg DM) and LK (0.60 kg DM) compared to those observed in CTF (2.16 kg DM) and NANOLIPE® (2.17 kg DM) with under- or overestimation of the digestibility of DM, NDF, ADF, HEM, ED, OM and CP estimated by internal indicators. The NANOLIPE® got high recovery rate (100.46%) and the digestibility coefficients of all nutrients were similar to those obtained by the CTF. The NANOLIPE® indicator was efficient to estimate fecal output and apparent digestibility of dietary nutrients in horses when provided for two days, with a daily application and start collecting feces 24 hours after administration.
