Evaluation of internal markers in digestibility estimation for sheep and goats.

The objective of this study was to compare the indirect methods of obtaining digestibility with the direct method of total fecal collection to estimate the apparent digestibility of nutrients in sheep and goats supplemented with non-protein nitrogen. Five goats and five sheep with no defined racial pattern were used, distributed in two 5 × 5 Latin squares, with split plots, considering the diets as plots and the apparent digestibility determination methodologies as subplots. The diets were composed of buffelgrass hay and the addition, via ruminal infusion, of increasing amounts of nitrogen supplementation in order to gradually raise the CP level of the basal diet in intervals of 2% points, that is, + 2, +4, + 6 and + 8%.

Micro-level transmission of monetary policy shocks: The trading book channel.

We open the black box of the monetary policy transmission mechanism with a granular model that considers the balance-sheet composition and network relationships of each economic agent. Though there are several well-documented channels through which monetary policy operates, we focus on the overlooked trading book channel, which arises because of adjustments in the accounting value of trading book exposures on banks' balance sheets that have to be marked to market when interest rates change. Variations in banks' net worth due these adjustments are used as input to a network model that incorporates the financial and corporate sectors.

Etiology of anemia of blood donor candidates deferred by hematologic screening.

Objective: Iron deficiency is the most common cause of anemia and one of the main factors in the clinical deferral of blood donors. This fact prompted the current study that aimed to determine the prevalence and etiology of anemia in blood donor candidates and to evaluate the hematological screening technique used for the exclusion of these donors.

Methods: This was a prospective study that compared two groups (Anemic and Non-anemic).

Catheter-induced urethral trauma in cats with urethral obstruction.

Fifteen cats were evaluated with urethral obstruction. Penile trauma by catheterization was the major indication for perineal urethrostomy. Ten cats had developed a urethral stricture and five had rupture of the urethra following medical management.

[Population parameters for Triatoma sordida Stal, 1859: the most frequent vector for Chagas disease in the Triângulo Mineiro (Heteroptera, Triatominae)].

Triatoma sordida is the most frequent vector for Trypanosoma cruzi, Chagas, 1909, in Uberaba, State of Minas Gerais. The objective of this study was to construct a dynamic life table for Triatoma sordida with the aim of supplying support data for controlling its populations.
