Manejo pré-abate de ovelhas de descarte: perdas de peso corporal, qualidade da carne e comportamento animal

The aim of this study was to know the behavior of Santa Inês ewes in different physiological stages during the pre-slaughter management, as well as their body weight loss, blood hematocrit values and meat quality. 21 discard ewes were used, arranged into the following treatments: T1 = ewes which remained in lactation for 60 days with their respective lambs and slaughtered one day after weaning; T2 = ewes which remained in lactation for 60 days with their respective lambs and one more period of approximately 30 days without the lambs and afterwards slaughtered; and T3 = ewes which remained in confinement for 60 days and did not give birth during the year. The weight of ewes after transportation was lower for T1 in comparison with T2. Blood hematocrit values of ewes before and after transportation and after fast in the waiting pen were not different among the treatments, with mean value of 58.50%. We concluded that the quality of meat of discard ewes in different physiological stages is not altered by pre-slaughter management, when correctly performed (avoiding animal stress), concerning meat pH.

Estudo epidemiológico sobre as perdas reprodutivas em bovinos leiteiros: ocorrência de neospora caninum, brucella abortus, herpesvírus bovino tipo-1 e leptospira spp. em uma propriedade do município de São Carlos-SP

The aim of this work was draw an endemic level of reproductive losses and determine positivity for four infectious agents related to reproductive problems in dairy cattle on a property in São Carlos city. Blood serum samples were collected of 142 breeding animals more than two years old, from which 21.1% showed history of abortions or stillbirths in at least one pregnancy. Immunofluorescent antibody technique, tamponated acidified antigen test, serum neutralization technique and microscopic agglutination test, were used for detection of antibody anti-Neospora caninum, anti- Brucella abortus, anti-Bovine Herpesvirus Type-1 (BoHV-1) and anti-Leptospira spp , respectively. The serological tests carried out showed that 28.9% of the animals had titers greater than or equal to 100 of anti-Neospora caninum. Viral neutralization tests demonstrated that 26.8% of the animals had titers greater or equal to 256 for antibody anti-BoHV-1.Only 7.7% of the animals studied had titers equal to or greater than 100 in the microscopic agglutination test for Leptospira spp. There weren’t observed positive reactions to the tamponated acidified antigen test for diagnosis of bovine brucellosis. The study suggests the presence of BoHV-1, N. caninum and Leptospira spp in contact with dairy cattle property and could be involved in the occurrence of abortions and stillbirths in cattle. Reproductive losses are endemic and implies a possible behavior of chronic infections caused by these microorganisms.

Modelo hidrológico SWAT na determinação das perdas de solo na bacia hidrológica do Rio Pardo - Botucatu/SP

The objective of this work was to evaluate the sediment production in the initial part of the Pardo River Basin - Botucatu/SP from 1994 to 1999, using the mathematical hydrological model SWAT. It was used topographic maps and satellite data manipulated in GIS using the software SPRING 5.1.6. The simulation of sediment production was generated with the aid of an interface between the hydrological model SWAT 2009 with ArcView ®, version 9.3. The maps of Soil, Land Use and Digital Elevation Model (DEM) were generated in the GIS-SPRING 5.1.6 and exported to ArcSWAT 2009. The tabular data related to the parameters of soil and meteorological parameters were entered directly to the SWAT. The model allowed to estimate the sediment production. A sediment average production rate of 33.866 ton ha-1 over the six years of study was computed in the point of discharge of the basin.

Mapeamento, erodibilidade e tolerância de perdas de solo na sub-bacia do Ribeirão das Perobas

The land use conservation planning requires knowledge of the soil characteristics, natural susceptibility to erosion and the soil loss limit. In this context, the objectives of this study were to perform a detailed soil survey of Ribeirão das Perobas watershed, located in Santa Cruz do Rio Pardo, São Paulo State and to determine and map the erodibility and soil loss tolerance of the soil classes found in the survey. The following techniques were used to perform the detailed soil survey: photopedology, field sampling, physical analysis, chemical analysis, and morphological description of the soil samples and profiles. The erodibility was determined by the methods described by Denardin (1990) and Mannigel et al. (2002), and the determination of soil loss tolerance followed the methodology of Mannigel et al. (2002). The results of erodibility determined by the methodology of Denardin (1990) were not discrepant and they did not distinguish soils that are known to have different susceptibility to erosion., w\Whereas, using the methodology of Mannigel et al. (2002), very high or very low erodibility values were observed in soils with extreme contents of sand silt or clay. The most influent variable to the soil loss tolerance results was the correction factor for the textural gradient of clay between soil horizons.

Diagnóstico e proposição de medidas para o controle das perdas de água no sistema de abastecimento de Guaratinguetá

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses

Implicações do pronto-atendimento psicológico de emergência aos que vivenciam perdas significativas

A proposta deste trabalho consistiu em compartilhar um serviço de pronto-atendimento psicológico às pessoas que vivenciam uma perda significativa, seja por morte de uma pessoa de vinculação importante, como a de um familiar ou amigo, óbito de um paciente ou perda da saúde quando do adoecimento e/ou hospitalização, entre outros, e discutiu os resultados de tal serviço. O enfoque metodológico baseou-se na análise do processo de estruturação e implantação de um serviço dessa especificidade em um hospital público universitário, onde os autores desenvolvem a assistência aos que vivenciam esses processos de perda. Os resultados apontaram a importância da oferta desse serviço, que foi demandado tanto por aqueles que vivenciam o luto pela perda de saúde ou pela morte de uma pessoa significativa como por profissionais de educação e saúde.

Perdas de água e solo sob diferentes padrões de chuva simulada e condições de cobertura do solo

Este trabalho foi realizado com o objetivo de determinar as perdas de solo e água em um Argissolo Vermelho-Amarelo, submetido a quatro diferentes padrões de precipitação de chuva simulada e duas condições de cobertura: área com solo descoberto e com palhada após plantio de milho. O experimento foi conduzido no Campo Experimental da Embrapa-Agrobiologia, localizado no município de Seropédica-RJ, e consistiu na aplicação de chuvas simuladas com diferentes padrões, caracterizados como avançado (AV), intermediário (IN), atrasado (AT) e constante (CT), em uma área amostral de 0,80 m de largura por 1,0 m de comprimento. Utilizando um simulador de chuvas portátil, foram aplicadas chuvas com 30 mm de lâmina total durante 60 minutos. Nos padrões com intensidade variada, o pico de precipitação foi de 110 mm h-1. Os resultados obtidos possibilitaram concluir que a cobertura do solo com resíduos de milho reduziu substancialmente as taxas e perdas de água e solo, principalmente para o padrão de chuva constante, indicando que a palhada deixada sobre o solo após a colheita auxilia de maneira efetiva no controle da erosão.

Abdominoplastia vertical para tratamento do excesso de pele abdominal após perdas ponderais maciças

INTRODUÇÃO: As cirurgias bariátricas são cada vez mais frequentes no tratamento dos pacientes portadores de obesidade mórbida. A grande perda ponderal decorrente desses procedimentos causa excesso de pele e de tecido subcutâneo em todo o corpo, especialmente na região abdominal. O objetivo deste trabalho é apresentar a técnica de abdominoplastia vertical como alternativa para a ressecção do excesso de pele nesses pacientes. MÉTODO: Foram avaliados, retrospectivamente, os prontuários de 40 pacientes submetidos ao procedimento entre 2004 e 2009. O grau de satisfação dos pacientes foi avaliado através de escala subjetiva, com notas variando de 0 a 10. RESULTADOS: Vinte e cinco por cento dos pacientes apresentaram pequenas complicações, sendo 3 seromas, 3 pequenas deiscências e 5 cicatrizes hipertróficas, todas tratadas ambulatorialmente. Dois terços dos pacientes relataram alto grau de satisfação, considerando seus resultados bons (notas 7 ou 8) ou ótimos (notas 9 ou 10). CONCLUSÕES: A técnica de abdominoplastia vertical aparece como uma nova opção para o tratamento do excesso de pele abdominal em pacientes ex-obesos.
