The effects of replacing monensin with sodium bicarbonate in diets for confined heifers on weight gain (WG), dry matter intake (DMI), feed:gain ratio (FGR) and rumen fermentation parameters were evaluated. Fifity six heifers were utilized (Santa Gertrudis x Braunvieh). Diets were formulated with two levels of concentrate (50% and 80% concentrate) with sodium monensin or sodium bicarbonate. The DMI was higest in heifers with an intake of 80% concentrate. There was not difference when the same concentrate levels were evaluated in relation to the DMI. The heifers at 80% concentrate showed highest WG. There was no significant difference in relation to WG between monensin and bicarbonate treatments and levels concentrate proportions. There were significant effects regarding FGR between treatments. The heifers on 80% concentrate showed lowest FGR. In the evaluation of N-NH3, the highest values were observed, on the whole, at 80:20 diets in relation to 50:50 diets. In the additive use, the monensin on 80:20 diets promoted the highest values of N-NH3 at 1 for 9 hours after feed intake. In the values of ruminal pH, the bicarbonate increased the values on 50:50 at 6 for18 hours after feed intake, in relation to the 80:20 diet. In this case, it was concluded that the use of sodium bicarbonate in diets for confined finishing heifers is a viable option for the replacement of monensin sodium.

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.

Currently, the food market is a great competition. It is no longer unanimously in the CMC powder drinks, as in the past, xanthan gum, always seeking to develop more economic alternatives, such as guar gum. It is clear, therefore, it is of vital importance to understand thoroughly the operation of a particular product in different process conditions and with different materials so that we can develop and adapt both new processes and products to new market reality

The purpose of this study was to evaluate in vitro antimicrobial activity of chlorhexidine gel and liquid 2%, and 2% sodium hypochlorite on Candida albicans, Enterococcus faecalis, Escherichia coli in root canals. For this, we used 40 human single-rooted teeth were divided into 4 groups (n = 10) according to assist the chemical used: 1) 2% chlorhexidine liquid, 2) 2% chlorhexidine gel, 3) sodium hypochlorite 2%, and 4) physiological saline (control). Content were collected immediately after root canal instrumentation and after 7 days of biomechanical. For the samples was conducted to evaluate the antimicrobial activity and the results were subjected to statistical analysis of Kruskal-Wallis and Dunn's test with a significance of 5%. It was found that chlorhexidine gel and liquid as well as sodium hypochlorite were effective against the microorganisms tested
