Objetivou-se avaliar o perfil bacteriano total do leite caprino associado ao nível de adoção de práticas higiênicas durante a ordenha, em vinte e quatro Unidades Produtoras (UP) no município de Monteiro-PB. As coletas foram realizadas diretamente do latão de leite de cada produtor, após a ordenha e durante três dias consecutivos, totalizando assim, setenta e duas amostras. As amostras de leite foramacondicionadas em frascos plásticos contendo o conservante Azidiol e enviados ao laboratório da Universidade Federal Rural de Pernambuco pertencente à Rede de Laboratórios de Controle da Qualidade do Leite (RBQL) em Recife - PE para a contagem bacteriana total (CTB). Para avaliação do manejo de ordenha, os dados primários foram coletados utilizando-se um questionário. As propriedades foram agrupadas segundo o nível de adoção de práticas higiênicas realizadas na ordenha, em bom, regular e ruim. Observou-se, que 29,2% das propriedades foram consideradas boas, 46,0% foram classificadas em regulares e 25,0%, em ruins.Verificou-se, que 20,8% das UP apresentaram médias superiores a 1500.000 UFC/mL, valor considerado alto. Apenas 25,0% das propriedades avaliadas encontram-se dentro do limite estabelecido pela legislação que é de 500.000 UFC/mL. Acredita-se que a inclusão de novas tecnologias visando à adoção de medidas corretas durante o processo da ordenha é essencial, por melhorar a qualidade e a padronização da higiene do leite. Atenção especial deverá ser dada também a água utilizada durante o procedimento de obtenção do leite. Goat Milk Quality Prior to Implementation of Good Agricultural Practices: Case Studies. Abstract: This study aimed to assess the total bacterial profile of goat milk associated with level of adoption of hygienic practices during milking, in twenty-four Production Units (PU) in the town of Miller-PB. The samples were taken directly from the tin of milk from each producer, and after milking for three consecutive days, thus totaling seventy-two samples. Milk samples were packed in plastic bottles containing the preservative and sent to the laboratory azidiol Federal Rural University of Pernambuco belongs to the Network Laboratories Quality Control of Milk (RBQL) in Recife - PE for total bacterial count (CTB). To evaluate the management of milking, the primary data were collected using a questionnaire. The properties were grouped according to level of adoption of hygienic practices during milking performed in good, fair and poor. It was observed that 29.2% of properties were considered good, 46.0% were classified as regular and 25.0% in ruins.Verificou is that 20.8% of PU had averages exceeding 1500,000 CFU / mL, which is considered high Only 25.0% of the properties are within the limit established by legislation that is 500,000 CFU / mL. It is believed that the inclusion of new technologies towards the adoption of correct measures in the process of milking is essential for improving the quality and standardization of milk hygiene. Special attention should also be given to water used during the procedure of getting the milk.

Visible and near-infrared (Vis-NIR) spectroscopy is a tool to determine soil spatial variability and has been used to map soils and their properties. Considering that physical, chemical, mineralogical, and morphological soil properties can affect the intensity and the depth of the spectral reflectance band in the Vis-NIR region, the objectives of this work were to: (i) evaluate the potential of the reflectance inflection difference (RID) to discriminate soils; and (ii) verify potential spatial correlations of the RID with soil properties, compared with the full spectra, in order to build thematic maps at a field scale. In a farm of 375 ha, 78 soil samples from the 0.87?0.92-m depth were collected in a regular grid of 200 m, with a focus on the soil diagnostic horizon (Bw horizon). The sampled soils were a Latossolo Vermelho-Amarelo ́ acrico (Haplic Ferralsol) and a Latossolo Ver- melho distrofico ́ (Rhodic Ferralsol). Twenty-two physical, chemical, mineralogical, and morphological soil properties were determined, and the Vis-NIR spectra between 400 and 2500 nm were measured. Considering the presence of an inflection band and its relationship with soil properties, the spectral bands used to calculate the RID were between (base 1/base 2): 400?510, 730?930, 1290?1450, 1800?1950, 2000?2218, and 2218?2290 nm. The RID failed to map the spatial variability of soil properties, with a Kappa index of 39%; therefore, it is not a good parameter for building thematic maps of soil parameters. In addition, the complete spectrum (mainly in 400?510, 730?930, 1290?1450, 1800?1950, 2000?2218, and 2218?2290 nm) was better spatially correlated with soil properties than the decomposition of the spectrum by the RID. Soil classification and level of dis- cretization as affected by spectral variability were also discussed here. Three soil groups were discriminated mainly by the Ki and Kr indexes and clay content. Moreover, the variability of the spectra was conditioned by the spatial variability of the mentioned variables. The clay content for soils with a discrepant particle size (group 1 compared with groups 2 and 3) and the Ki and Kr indexes for soils with a homogeneous particle size (between groups 2 and 3), associated with the full Vis-NIR spectral analysis, allowed building thematic maps with a good precision, without the need of mathematical models; this was possible by the modification of the reflectance intensity and the size of the concavity of the spectral band.
