The intake and performance of lambs fed with sugarcane silages treated with whitewash and chloride sodium were evaluated. Seven treatments were used: untreated silage (control); silages treated with 0.5; 1.0 and 1.5% of CaO (whitewash); and silages treated with 0.5; 1.0 and 2.0% of NaCl, with four replicates per treatment. The animals were fed a higher amount of dry matter and total digestible nutrients when the sugarcane silages were treated with 0.5% of NaCl, 1.0 and 1.5% of CaO. The intake of neutral detergent fiber and crude protein increased when the lambs were fed silages treated with 0.5% of NaCl and 1.0% of CaO. The average daily gain did not differ among treatments. The inclusion of 0.5% of sodium chloride and 1.0% of whitewash in sugarcane silages increased the intake and improved the performance of lambs.

The purpose of this study was to evaluate in vitro the shear bond strenght to bovine dentin, during 24h and 30 days with the following variables: resin cements Enforce and Panavia F; aesthetics restorative materials Art Glass, IPS Empress 2 and Targis, with surface treatment with microetching with aluminium oxide, fluoridric acid and silane. Two hundred eighty eight sound bovine teeth from 3 years old animals constituted the samples after inclusion on polyester resin box. lnstron model 430 Universal Testing Machine, a crosshead speed 0,5 mm/min and load cells of 500 Kg, was used for shear bond strenght testing (MPa). The results were statistically analysed by ANOVA The best result was obtained with /PS Empress 2, microetched with aluminium oxide, fluoridric acid and silane, cemented with Panavia F and stored in distilled water, 3f'C during 30 days
