Characteristics of the dairy goat primary sector at the Rio de Janeiro State, Brazil.

A survey was done based on 19 goat shepherds at counties of Centre-highlands, Northern and North-western regions of the Rio de Janeiro State and at the county of Pedra Dourada, Zona da Mata region, State of Minas Gerais. We aimed to characterise the primary sector of the goat milk production chain settled at those regions. Therefore, questionnaires were applied in order to depict profiles of the shepherds, their families, the role of the wife in the activity, the resources available, dependence on income generated by the activity, and how producers administrate their business. Farms were distributed in five strata according to the following daily milk production averages and standard deviations: 8.8 ± 0.9, 15.7 ± 3.9, 22.6 ± 2.7, 34.4 ± 3.4, and 183.8 ± 54.2 L/d. Approximately 42% of the interviewed producers conducted their activities according to a household production model and the income earned was exclusively from the dairy goat husbandry. Sons and daughters performed an important role in the business (27.80%), but most of them (62.73%) worked out at non farm activities. The percentage of wives that worked directly in the activity (@47%) indicated that it could contribute to gender equity in the rural environment. Most of the production systems (63.16%) presented positive gross margins. We have noticed, however, that shepherds perceived only the business gross margin and that the most accurate registries taken were those related to revenues. In general, producers of the higher strata were favoured by their larger production scale, but asymptotic behaviours for costs and amounts invested in animals, equipments and buildings were observed. These characteristics should be considered when policies related to the dairy goat primary sector have to be planned

Kinetics of digestion of low-quality forage grazed by beef cattle fed supplements containing increasing levels of rumen undegradable protein

This experiment was conducted to evaluate the degradation kinetics and microbial efficiency of beef cattle grazing on low-quality forage and receiving supplements with different levels of rumen undegradable protein (RUP). The animals grazed on palisade grass pasture solely or this pasture and supplement containing 40 or 60 g of RUP per 100 g of crude protein (CP). The degradation profiles of neutral detergent fiber, fiber carbohydrates, and neutral detergent insoluble protein were interpreted kinetically by using a decreasing logistic model. Treatments (no supplement, or RUP at 40 or 60 g−1 100 g CP) did not affect rumen fill; however, the increase in the indigestible fiber carbohydrate fraction that occurred at the expense of the digestible fiber carbohydrate fraction resulted in a greater rumen fill effect. The palisade grass showed a significant proportion of its nitrogen in the form of slowly degradable protein as neutral detergent insoluble protein, which amounted to 26 g per 100 g CP. Supplementation with 40 g of RUP per 100 g CP decresead the indigestible fraction of the low-quality forage. However, the absence of a rumen-fill effect demonstrates that the additional supply of nutrients contributes greatly to increasing growth efficiency and use of the available energy from the forage by the ruminal microorganisms

Câncer gástrico: uma revisão de literatura

This article aims to scan the current medical literature on gastric cancer, focusing on epidemiology, pathophysiology, risk factors, prevention and currently applied treatments. This is an integrative review using the VHL, SciELO, LILACS and PubMed as databases over the last 5 years. 252 articles on the topic were evaluated with an emphasis on a synthesis of the most recent knowledge and greater scientific consistency. Gastric cancer (GC) is the second leading cause of cancer death and the fourth most common cancer in the world. The prognosis of GC is essentially based on its staging and is related to the depth of tumor invasion and the presence of lymph node metastases. It is concluded that the presence of a lesion with an insidious or even asymptomatic presentation contributes to the high rate of diagnoses already in advanced stages of the disease, compromising treatment.Este artigo tem por objetivo realizar uma varredura da literatura médica vigente sobre a bibliografia acerca do câncer gástrico, com enfoque na epidemiologia, fisiopatologia, fatores de risco, prevenção e tratamentos aplicados atualmente. Trata-se de uma revisão integrativa utilizando como base de dados a BVS, a SciELO, o LILACS e o PubMed, nos últimos 5 anos. Foram avaliados 272 artigos sobre o tema com ênfase em uma síntese dos conhecimentos mais recentes e de maior consistência científica. O câncer gástrico (CG) é a segunda causa de morte por câncer e o quarto câncer mais comum no mundo. O prognóstico do CG baseia-se essencialmente no seu estadiamento e está relacionado com a profundidade de invasão tumoral e com a presença de metástases linfonodais. Conclui-se que a presença de lesão com apresentação insidiosa ou até mesmo assintomática contribui para o elevado índice de diagnósticos já em estágios avançados da doença, comprometendo o tratamento. &nbsp

Checklist of the birds of Mato Grosso do Sul state, Brazil: diversity and conservation

Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat
