Substituição de monensina sódica por bicarbonato de sódio em dietas de novilhas confinadas

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.

Substituição da farinha de peixe por farinha de vísceras de aves na alimentação do piavuçu Leporinus macrocephalus

The present study aimed at evaluating the productive performance of Leporinus macrocephalus fed with different levels of inclusion of poultry viscera meal replacing fish meal. The experiment was conducted in a stove located in the Universidade Estadual do Oeste do Paraná during 45 days. We used 200 fish with average initial length of 4.7 ± 0.37 cm and average initial weight of 1.407 ± 0.03 g, distributed in 20 net-cages. The experimental design was randomized with five treatments and five replicates with five levels of replacement of fish meal by poultry viscera meal (0, 25, 50, 75, 100%). The parameters evaluated were the productive performance and the chemical composition of animals. The inclusion of poultry viscera meal in the substitution of fish meal in the feeding of Leporinus macrocephalus can be used without impairing the performance of the animals.

Avaliação in vitro da resistência adesiva ao cisalhamento entre a dentina bovina, cimentos resinosos e materiais restauradores indiretos, tratados ou não com jato de óxido de alumínio, ácido fluorídrico e silano

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

Substituição de importações e as origens da indústria petrolífera no Brasil

The aim of this article is to introduce the context when was created the Brazilian oil industry during the period known as “process of substitution of importation”, under influence of the 1930´s Liberal Revolution. The absence of national private capital, ally to disinterest of multinationals oil companies for developing this sector, particularly during the 1930´s, forced Brazilian State to structuralize a system to regulate and to stimulate oil production from a new entity: the National Oil Council, which takes for itself the task to building the Brazilian oil industry during the period 1938-1953.
