Commercial cuts and carcass characteristics of sheep and goats supplemented with multinutritional blocks / Cortes comerciales y característica de la canal de borregos y cabritos suplementados con bloques multinutricionales

ABSTRACT Objective. Aimed to identify the weight and yield of the commercial cuts, muscularity, and adiposity in the carcasses of sheep and goats grazing in the Caatinga supplemented with different sources of supplementations; these include feed-blocks. Material and methods. Sixty non-castrated males an initial average body weight of 18.63 ± 1.93 kg were used: 30 goats and 30 sheep all animals did not have a defined breed standard (WDBS). The experimental design used was entirely randomized (DIC), in factorial scheme 3x2 (three types of supplementation: mineral salt, MBs and MBs + buffel hay, and two species: sheep and goats) and 10 replications. Animals were raised in a rangeland grazing system in an area with vegetation characteristic of Caatinga ecosystem under three types of supplementation: 1: only mineral salt; 2: Feed blocks (MBs); and 3: MBs + buffel hay There were measured the weight, yield and the components of left half-part of carcass of lambs and kids. Results. The sheep were superior to goats in carcass conformation, loin-eye area, index of muscularity of the leg and compactness index of the leg while the goats were superior to sheep in leg muscles weight. Conclusions. Sheep and Goats, when fed with supplementation of pasture feeding blocks in the Caatinga ecosystem; Supplementation with mineral salt and Multinutritional Blocks with and without Buffel can be used to improve herds in the caatinga, with similar results among the three. Sheep show more adiposity of meat than goats, in contrast, goats have higher musculature than sheep when fed with feed blocks.

RESUMEN Objetivo. Con el objetivo de identificar el peso y rendimiento de los cortes comerciales, musculatura y adiposidad en las canales de borregos y cabritos pastando en la Caatinga suplementado con diferentes fuentes de suplementos; Estos incluyen bloques de alimentación. Materiales y métodos. Se utilizaron 60 machos no castrados con un peso corporal medio inicial de 18,63 ± 1,93 kg: 30 borregos y 30 cabritos, todos los animales no tenían un estándar de raza definido (WDBS). El diseño experimental utilizado fue totalmente al azar (DIC), en esquema factorial 3x2 (tres tipos de suplementación: sal mineral, MBs y MBs + heno buffel, y dos especies: borregos y cabritos) y 10 repeticiones. Los animales fueron criados en un sistema de pastoreo de pastizales en un área con vegetación característica del ecosistema de Caatinga bajo tres tipos de suplementación: 1: sal mineral solamente; 2: Bloques de alimentación (MBs); Y 3: MBs + heno buffel Se midió el peso, el rendimiento y los componentes de la mitad izquierda de la carcasa de corderos y cabritos. Resultados. Las cordeiros fueron superiores a los cabritos en conformación de carcasas, área de lomo, índice de musculatura de la pierna y índice de compacidad de la pierna mientras que los cabritos fueron superiores a las cordeiros en el peso de los músculos de las piernas. Conclusión. Cordeiros y cabritos, cuando se alimentan con suplementos de bloques de alimentación de pasto en el ecosistema de Caatinga; La suplementación con sal mineral y Bloques Multinutritivos con y sin Buffel puede ser utilizada para mejorar los rebaños en la caatinga, con resultados similares entre los tres. Las cordeiros muestran más adiposidad de carne que los cabritos, en contraste, las cabritos tienen mayor musculatura que las cordeiros cuando se alimentan con bloques de alimentación.

Role of omega-3 polyunsaturated fatty acids in the production of prostaglandin E2 and nitric oxide during experimental murine paracoccidioidomycosis.

There has recently been increased interest in the potential health effects of omega-3 polyunsaturated fatty acids on the immune system. Paracoccidioidomycosis is the most important endemic mycosis in Latin America. Macrophages have a fundamental role and act as first line of organism defense. The purpose of this study was to analyze the effect of n-3 fatty acids on the production of PGE2 and NO by mice infected with Pb18 and fed a diet enriched with LNA for 8 weeks. To study the effect of omega-3 fatty acids on macrophage activity during experimental paracoccidioidomycosis, mice were infected with Pb18 and fed a diet supplemented with LNA. PGE2 in the serum of animals was analyzed and NO in the supernatants of macrophages cultured and challenged in vitro with Pb18 was measured. Omega-3 fatty acids seemed to decrease the production of PGE2 in vivo in the infected group fed an LNA-supplemented diet during the 4th and 8th weeks of the experiment. At the same time, we observed an increase in synthesis of NO by peritoneal macrophages in this group. Omega-3 fatty acids thus appear to have an immunomodulatory effect in paracoccidioidomycosis.

Qualidade da semente do gergelim preto (Sesamum indicum L. ) em diferentes épocas de colheita / Quality of black sesame seeds (Sesamum indicum L. ) at different harvest times after sowing

O objetivo do presente estudo foi avaliar a qualidade da semente do gergelim preto colhida em diferentes épocas após a semeadura. As sementes utilizadas foram provenientes de quatro épocas de colheita (122, 129, 136 e 143 dias após semeadura). A avaliação da qualidade das sementes foi determinada pelo teste de germinação, primeira contagem de germinação, comprimento de plântulas, teste de condutividade elétrica, e massa de 100 sementes. Os dados foram submetidos à análise de variância, e, para avaliação da condutividade elétrica, utilizou-se esquema fatorial 4x4 (quatro épocas de colheita x quatro tempos de embebição), as características significativas foram submetidas ao teste Tukey, a nível de 5% de significância. A época que propicia melhor qualidade das sementes de gergelim preto é evidenciada na colheita aos 136 dias após a semeadura. No entanto, deve-se considerar a padronização das épocas de colheita em função do estádio fisiológico da planta, uma vez que o número de dias para cada fase é específico para cada condição.

The purpose of this study was to evaluate the quality of black sesame seeds harvested at different times after sowing. The seeds used were derived from four different harvest times (122, 129, 136 and 143 days after sowing). The assessment of the quality of the seeds was determined by standard germination, first count germination, seedling length, electrical conductivity and mass of 100 seeds. The data were submitted to variance analysis, and the evaluation of the electrical conductivity used a 4x4 factorial arrangement (four harvesting times x four soaking times), the significant features were submitted to Tukey's test at 5% significance. The time that provides a higher quality of black sesame seeds is shown by the harvest at 136 days after sowing. However, the standardization of the harvest times due to the physiological stage of the plant should be considered, since the number of days for each phase is specific of each condition.

Arteriovenous malformation of the mandible: review of literature and case history.

Vascular malformations of the jaws can lead to disastrous complications, but there seems to be no consensus as to their treatment. The literature presents the pathophysiology and clinical aspects of these lesions, as well as the divergent views of the authors. Treatment by catheterization and embolization, with direct transosseous injection of cyanoacrylate, appears to be the least harmful and most permanent treatment in certain conditions, as evidenced by the case of this 9-year-old patient having a high-flow mandibular vascular malformation
