Item Avaliação das boas práticas agropecuárias aplicadas nas propriedades rurais fornecedoras de leite de uma unidade de beneficiamento de leite e derivados situada na Mata Sul de Pernambuco(2024-08-28) Silva, Eliabe Lieda da; Rolim, Maria Betânia de Queiroz; http://lattes.cnpq.br/5676854885081836; http://lattes.cnpq.br/1112925648971271The Estágio Supervisionado Obrigatório (ESO) is a mandatorysubject for the eleventhsemester of the Bachelor's Degree in Veterinary Medicine at the Universidade Federal Rural de Pernambuco (UFRPE). It is based on 420 hours of practicalexperience in a specificsub-areaofveterinary medicine, with the aim of qualifyingstudents to performtheirduties by obtaining the title of veterinarian. In this sense, the main objective of this report is to demonstrate the main activitiesperformed by student Eliabe Lieda Da Silva, under the guidance and supervision of Professor Dr. Maria Betânia de Queiroz Rolim; Sanitarian Maria Eugênia Farias Gama; and Veterinarian and Technical Manager Samantha Lopes De Barros, respectively. Itssecondary objective is to evaluate the good agricultural practicesadopted on rural properties that supplymilk to the FACO Dairy Industry. The ESO tookplace from April 1 to June 19, 2024, distributed in the EnvironmentalSurveillance of the Sanitary District VI of Recife - PE and in the Indústria de Laticínios FACO LTDA of Ribeirão - PE. The internshipallowed the possibility of being in different areas, experiencingexperiences and acquiringtheoretical and practical knowledge in the area of public health and inspection of products of animal origin, fundamental for training in veterinary medicine.Item Desenvolvimento de um procedimento analítico para a determinação espectrofluorimétrica de nitrato e nitrito em leite explorando um composto de coordenação à base de európio (III)(2020-10-23) Gomes, Larissa Mayara da Silva; Lavorante, André Fernando; http://lattes.cnpq.br/1011018535020717; http://lattes.cnpq.br/1083349586557028Milk is a very important food for humans, being a great source of proteins and minerals essential for maintenance of life. Due to this fact, public and private policies emphasize the need to produce quality products. The milk goes through several management processes, from milking until arrive at supermarket’s shelves, which are fundamental for its quality maintenance. Usually investments are made in air-conditioned facilities, reservoirs and equipment made of antioxidant material and training of those involved in the production process. However, these points do not show an obvious profitable end for entrepreneurs in dairy industry. Based on this fact, some companies resort to more practical methods, such as addition of adulterants in milk, so that it is conserved. The fundamental point of using these additives is inhibition of microbial proliferation. Sodium and potassium nitrites and nitrates are on the list of preservatives widely used by the food industry. The use of these two anions in food is related to their preservative power, however, its excess in a body can cause problems due to their toxicity, causing an endogenous formation of nitrosamines that have potentials carcinogenic, teratogenic and mutagenic potentials. The objective of this work is to develop a methodology that aims to determine nitrate and nitrite in milk samples consumed by population of Recife in Pernambuco’s state, through interaction of these anions with a coordination compound [Eu(12-crown-4).2phen].Cl3, responsible for system's fluorescence, since the interaction with nitrate and nitrite partially suppresses its fluorescence in this way, enabling the linear correlation between the concentration of the analytes and quenching of the coordinating compound. Those analytical answers were obtained by using with concentration from 0.5 to 10.0 mg.L-1, obtained a correlation coefficient readings were performed varying the concentration between 0.5 to 10.0 mg.L-1 {RNO3 = 0.9941 / RNO2 = 0.995}, demonstrating the feasibility of the proposed method for analysis of nitrate and nitrite.Item Análise multivariada de varíaveis ambientais, fisiológicas, parâmetros comportamentais e produção e qualidade de leite de vacas no verão(2019) Silva, Andreza Malena Guedes da Costa; Almeida, Gledson Luiz Pontes de; http://lattes.cnpq.br/2328849810614673; http://lattes.cnpq.br/0440362372584309The objective of this study was to determine, through the multivariate analysis, which, among the environmental, physiological and behavioral parameters, influence milk production and quality of lactating cows. This study was developed with data from a collection carried out in 2009. Sixteen lactating Girolando cows were selected. The animals were divided into four treatments of 0, 10, 20 and 30 minutes on a cooling system. The statistical analysis used was the multivariate, using the technique of Principal Component Analysis on the environmental, physiological and behavioral parameters have influence on milk production and quality. The rumination was opposite to the production, indicating that it was smaller, because it presents a condition of possible stress. The CCS was strongly influenced by the TR and in turn the FR. Both TR and FR presented the highest values in time of 0 minutes indicating a condition of thermal stress, which reflected in accentuated values of CCS, reducing milk quality. The use of 10,20 and 30 min cow exposure times to the evaporative adiabatic cooling system provided significant changes in somatic cell counts.Item Mastite subclínica causada por Staphylococcus aureus: impacto econômico e na saúde pública(2016) Rebouças, Rodolpho Almeida; Silva, Nivan Antônio Alves da; http://lattes.cnpq.br/3505011500604071; http://lattes.cnpq.br/9440496743455219Subclinical mastitis is a silent disease without macroscopic changes in milk or udder, being considered the disease that causes the greatest losses to dairy cattle. The losses caused by subclinical mastitis are significant, mainly due to the reduction in the production of the quarters, in addition there is a reduction in milk quality, interfering in the characteristics of this, important for the dairy products industry. Staphylococcus aureus is the main causative agent of this disease, being an important pathogen, also responsible for food poisoning. Foods involved in outbreaks and cases of staphylococcal food poisoning include raw milk, pasteurized milk and cheeses, with S. aureus being the most frequently isolated microorganism. Milk from cows with mastitis is the second food of animal origin in which there is greater percentage of isolation of Staphylococcus aureus Resistant Methicillin. Producers' awareness is extremely important to reduce the impacts caused by this disease, since, from the knowledge, measures can be taken to prevent and control the disease in the herds and consequently to produce a quality product, preventing it from causing problems. In view of this, this paper aims to elaborate a literature review on subclinical mastitis caused by S. aureus and its economic and public health impacts in order to support the preparation of didactic material for informative purposes for rural producers.
