This work aimed to evaluate the influence of daily supplementation with 10 g of polyethyleneglycol (PEG) associated with Sabiá shrub hay (Mimosa caesalpiniifolia Benth.) on the intake and digestibility of in goats and sheep. Twenty animals, ten sheep and ten goats were allocated in a randomized block design, with two treatments and two species: PEG group (supplemented with 10 g of PEG) and control group (without supplementation). Significant differences were not observed between treatments and species regarding the intake and digestibility of dry matter and neutral detergent fiber. Nevertheless, PEG supplementation enhanced the crude protein digestibility of Sabiá shrub hay from 33.96% to 38.74% in sheep and from 43.29% to 54.41% in goats, showing that the supplementation with PEG could become a good feeding strategy against the antinutritional effects of tannin of the forage plants.
