Abstract

There were used four castrated male horses, crossbred. It was used randomized block by design for four replications. The objective was to evaluate the effect of using samples, ground or in natura, in the precision of the mobile nylon bag technique (MNBT) in comparison to the total collection (CT) method in oder to estimate the apparent digestibility coefficient (DC) of nutrients of high-moisture grains silage of sorghum with low (SSLT) and high (SSHT) tannin in the feeding equine. No effect was observed for MNBT and CT methods with in natura sample for DC of DM, OM, CE, CP to SSLT (P>0.05), whose average values were 81.71, 84.23, 82.27 e 81.43%, respectively. The MNBT did not show acuracy to evaluate of DC of the SSHT, with ground and in natura samples. It was concluded that MNBT containing in natura sample should be used to determinating the DC of SSLT to DM, OM, CE and CP for equines.
