The 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.

Milk 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.

The aim of this study was to analyze changes in the total bacterial count of milk transported in bulk in isothermal tanks for the dairy industry, obtained from different producers in January, February and March (dry period) and April, May and June ( rainy season) of 2018. Milk samples were collected from the producers' expansion tank and samples from the truck's isothermal tank at the end of each route. The analyzes of CBT were performed in the Laboratory of the Milk Clinic located in Piracicaba - SP, accredited in the Ministry of Agriculture, Livestock and Supply (MAPA). The data were submitted to analysis of variance and the averages were compared by the tukey test at 5% of probability, performed through Sisvar Software. There was an increase in CBT during the bulk transport of refrigerated raw milk regardless of the periods. The CBT of the milk obtained in the rural property and transported in bulk up to the dairy, met the specifications of the Brazilian legislation.

Dairy cattle is one of the flagships in Brazilian agribusiness, in which Brazil occupies the fourth position in the world ranking of milk production, besides being a big consumer, pointing out the need to make use of more technified alternatives within the sector. milk production in order to keep up with market demand, with a guarantee of a quality final product, following all the norms recommended by the Ministério da Agricultura, Pecuária e Abastecimento (MAPA). The study aims to analyze the milk quality indicators that may be influenced by the management of milking under adequate and hygienic conditions, as well as other influential factors. Individual milk samples were collected, subjected to analysis, followed by evaluation based on the current legislation, MAPA standards No. 76 and 77. The milk component contents are in accordance with the legislation currently in force, noting changes only in urea nitrogen levels, but which can be easily corrected through diet.
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/9440496743455219
Subclinical 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.

Qualidade física, química e microbiológica do leite Tipo "C" comercializado em Recife
(1996) Mendes, Emiko Shinozaki; Sena, Maria José de
Com o objetivo de avaliar a qualidade do leite consumido pela população do Recife/PE, foram coletadas em 1993, amostras de leite pasteurizado tipo "C", das 4 marcas existentes no comércio, visando analisar suas propriedades físicas, químicas e microbiológicas. Das propriedades físicas estudou-se densidade e crioscopia, das químicas, teor de gordura, o extrato seco total, o extrato seco desengordurado as enzimas fosfatase alcalina e peroxidade e conservadores e reconstituinte. As análises microbiológicas constaram de contagem total de germes e do número mais provável de coliformes. O experimento foi conduzido através de um delineamento inteiramente casualizado, para tanto denominaram-se as marcas de leite em L1, L2, L3 e L4. Verificou-se que todas as marcas de leite não apresentaram o teor de gordura, de extrato seco total e o desengordurado mínimo exigido para o tipo. O leite da marca L4 apresentou-se fora dos padrões em todas as propriedades avaliadas. Todos os leites, exceto o da marca L1 apresentaram índice crioscópico elevado, o que sugere uma possível adição de água ao produto. A pesquisa da enzima peroxidase foi positiva e a da fosfatase alcalina, formol, água oxigenada e amido, foi negativa em todas as amostras. Nas análises microbiológicas, o leite da marca L4 apresentou o maior nível de contaminação em ambas as análises, enquanto na marca L2 o NMP de coliformes foi superior ao limite máximo permitido pela legislação. Portanto, pode-se concluir que o leite tipo "C", consumido na cidade do Recife apresenta baixa qualidade física e química, quando comparadas com as especificações da regulamentação vigente.
