RESUMO
The aim of this study was to evaluate dietary supplementation of different levels of dehydrated bocaiuva pulp (DBP) on the productive performance of laying quails, and on lipid oxidation, and quality in their eggs. A total of 120 quails were distributed in a completely randomized design with six treatments (0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% of DBP), five replicates and four birds per experimental unit. To evaluate lipid oxidation, the eggs were collected on five consecutive days at the end of the trial and distributed in a completely randomized experimental design in a 6 × 5 factorial scheme (eggs from quails fed different levels of DBP × evaluated fresh and after 7, 14, 21 and 28 days). The antioxidant potential of diets was improved (p < 0.05) when the DBP was added estimated as 2,2'-azinobis-3-ethylbenzothiazolin-6-sulfonic acid (ABTS) free radical scavenging capacity. No effect (p > 0.05) was observed on feed intake, hen-day egg production and feed conversion (kg/kg and kg/dz). There were no changes (p > 0.05) in the egg weight, Haugh unit, yolk index or eggshell percentage. Although no difference was observed (p > 0.05), when comparing each level with the control, a negative linear effect (p < 0.05) on specific gravity was observed. In addition, only the treatment with 0.5% pulp exhibited lower (p < 0.05) eggshell thickness compared with the control (0%). Thiobarbituric acid reactive substances (TBARS) analysis showed that as the dietary pulp level was increased, malondialdehyde content decreased linearly (p < 0.05) in the egg yolks, regardless of the storage period. Inclusion of DBP in the diets had no effect (p > 0.05) on the concentration of conjugated dienes in the eggs. The diets containing DBP showed a potential antioxidant effect, reducing the degree of lipid oxidation in egg yolk. However, no beneficial effects were observed on performance and egg quality.

Onze cães, sem raça definida, machos, adultos, não castrados e hígidos foram submetidos à punção aspirativa com agulha fina da próstata guiada por ultrassom para avaliação citológica e, após um período mínimo de sete dias, à videolaparoscopia para obtenção de fragmento prostático para avaliação histológica. Nos exames citológicos, dois animais apresentaram alterações celulares compatíveis com hiperplasia prostática benigna. Durante a videolaparoscopia, a colheita do fragmento prostático foi realizada de maneira rápida, não sendo observada hemorragia significativa após o procedimento. Os animais não apresentaram nenhuma complicação no período pós-operatório. Verificaram-se, ao exame histológico, morfologia e estrutura celulares e teciduais nos padrões normais do parênquima prostático em 10 animais; um único cão apresentou alterações celulares e teciduais sugestivas de hiperplasia prostática benigna.(AU)
Eleven healthy intact male mongrel dogs were submitted to prostate ultrasound fine needle aspirative puncture for cytologic exam and, after seven days or more, to videolaparoscopic fragment collection for further histologic evaluation. On cytologic exams, two animals presented changes which correlates with benign prostatic hyperplasia. During the videolaparoscopic proceedings, the prostate fragment collections were made in a quick way and no important hemorrhagic lost has been seen after the collection. The animals presented no complication after the surgeries. The histologic exams showed normal prostate parenchyma based on the cellular and tissue morphology and structure in ten dogs; only one presented cellular and tissue changes suggesting benign prostatic hyperplasia.(AU)
