This study aimed to evaluate the potential for milk production (MP), lactation length (LL) and calving interval (CI), analyze the environmental component affecting these traits, and to estimate the heritability and repeatability for milk production in crossbreds of Murrah buffalo cows in the state of Alagoas, Brazil. Data was composed of 487 observations of MP from 136 lactations recorded between the years of 2000 and 2010. In the analysis of variance for PL, the fixed effects were season (1- October to March, 2 -April to September) and year of the beginning of lactation, calving order and the LL (covariate). For the analysis of LL only the fixed effect of year of the beginning of lactation was included, and finally for the CI analysis, year of the beginning of lactation and calving order. The estimates of covariance were obtained using unicharacteristic analysis by Bayesian inference method, applyingan animal model, through Gibbs sampling. The additive genetic, permanent environment and residual effects were included as random effects in the model. The averages (sd) of MP, LL and CI were 2,218.03 kg (408.18), 282.59 days (39.48) e 422.49 days (91.05), respectively. All the effects included in the models were important (P<0.01). The estimates of heritability and repeatability for PL were 0.29 and 0.69, respectively. The results suggest that there is a moderate genetic variability among individuals for PL, indicating the possibility to obtain gain using selection.

O presente trabalho problematiza de que forma a escrita sobre a prática pedagógica pode contribuir para a promoção do empoderamento do professor. Para isto, desenvolvo uma pesquisa documental (LÜDKE; ANDRÉ, 1986), a partir das escritas de um grupo de professores, denominadas “Pipocas Pedagógicas”, crônicas em que são relatados acontecimentos de sua vida escolar, como profissionais e também como alunos. Estes professores são participantes do “Grupo de Terça” vinculado ao Grupo de Estudos e Pesquisa em Educação Continuada (GEPEC), ligado ao Programa de Pós Graduação da Faculdade de Educação da UNICAMP. A pesquisa, foi subsidiada por entrevistas com dois destes professores escritores, para melhor compreender como se desenvolve essa prática. A partir da análise deste material, o estudo perpassa sobre a importância da reflexão sobre a prática pedagógica, como forma de pesquisá-la. Estas temáticas foram necessárias para aprofundar o conceito de empoderamento, e poder pensá-lo dentro da realidade educacional, uma vez que a reflexão articulada ao conhecimento são fatores que podem levar ao empoderamento. Em função disso, realizei uma pesquisa bibliográfica, buscando o conceito de empoderamento em duas bases teóricas: SciELO (Scientific Electronic Library Online) e Anais da ANPEd (Associação Nacional de Pós-Graduação e Pesquisa em Educação), nos quais analisarei os artigos referentes aos Grupos de Trabalho: GT03 – Movimentos Sociais, Sujeitos e Processos Educativos; GT06 – Educação Popular; GT08 – Formação de Professores; GT18 – Educação de Pessoas Jovens e Adultas, fazendo um recorte entre os anos de 2000 a 2011. Desta forma, pretendo contribuir com reflexões que possibilitem (re)pensar formas de se chegar ao empoderamento docente e a consequência disto nos modos de se enxergar à educação

Means for milk, not otherwise specified, the product from complete and uninterrupted milking , in a hygienic, healthy cows, well fed and rested. The milk of other animals must be called according to origin of species. One of the main characteristics that defined the milk is the set of their sensory characteristics, and the main flavor. The control of milk quality in Brazil has been an important factor for the consolidation of the entire production chain, passing necessarily by the dairy industry. The production of milk with good quality guarantees, of course, food safety for consumers. The measures to obtain milk begin on the property, in carrying out correct procedures for milking, storage and transportation of the product also in the dairy. Later, in the laboratory evaluation of physicochemical properties, research fraud, and microbiological examinations. Finally, measures of health education are need for producers to become aware of the economic benefits by obtaining a better quality milk. The objective of this review is to emphasize the importance of using diagnostic procedures methods for the control of mastitis and consequently obtain better Milk quality

The conservation of raw milk for long periods of time under refrigeration can result in the lost of its quality. This happens because bacterias, capable of developing in low temperatures, as psichrotrophics, in milk, associates with its enzymatic activities, are capable to degradate it. Although the pasteurization of milk sufficiently diminishes the transmission of the illnesses, that generally eliminates such microorganisms, is not a total efficient process because many enzymes produced for such bacterias are termostable, being able to resist the treatment and to remain active, leading to the loss of the quality of milk and its derivatives. The Normative Instruction 51 of 2002 established that milk must be cooled and stored in the production property, what resulted increasing the incidence of such bacteria in population destined milk. In some parts of the world contaminated milk is causing serious risks to the health of the population, assuming great importance in Public Health, mainly in relation to the hygienic-sanitary conditions of the product. ANVISA establishes, thus, maximum bacteriological concentration that must be evidenced before commercializing the product, guaranteeing the quality of milk as proper for consumption. Based on these aspects, the objective of this work is the microbiological analysis of 30 milk samples type C, collected in bakeries of the city Botucatu, in the state of São Paulo. Analysis were made to determinate the most likely number of termotolerants coliforms, as well the number of colony units of psichrotrophics bacterias, the presence of Salmonella and the enumeration of positive Staphylococcus aureus, at the moment of purchase and validity of the products

This study aimed to conduct a review in most articles relating mastitis and reproduction. Mastitis affects the reproduction according to its time of occurrence and agent. Mastitis affects the interval interestrus and also increases the number of days open, the number of services per conception, the abortion rate and decreases the conception rate. The inflammatory reaction generated by mastitis and all the toxins produced by bacteria alter the entire endocrine profile of cows that experienced episodes of mastitis and thus affect their reproduction

This work consists of the implementation of the steps Define, Measure , Analyze , Improve and Control ( DMAIC ) to develop a Six Sigma project in an industry the food industry. The objective was to demonstrate a potential for reducing the occurrence of crushed cans in potting milk powder industry in a White Belt project. The food industry accounts for about 9 % of Brazil's gross domestic product ( GDP ), generating thousands of jobs . Among the major sectors of the food industry is the manufacturing sector of milk , occupies approximately 10 % of the total turnover of the food industry . Brazil is considered today one of the eight largest producers of milk powder in the world. The milk powder is packed , mostly for aluminum cans that are lined internally with varnishes and other materials to protect the milk of metals from aluminum. When the cans are dented food protection is compromised and may lead ingestion causing dis-eases such as botulism. Aiming to solve the problem of dented cans methodology was used as a case study with a quantitative approach through the DMAIC method. Some quality tools used in each step of the project as brainstorming , cause and effect diagram , flowchart , ef-fort and impact matrix, 5W1H , among other Pareto diagram is presented . A survey about the disposal of cans in the company verifying a mean loss and, from this histor-ical , a goal loss was calculated was performed . With the target set we calculated the annual saving design . During application of DMAIC was found that the highest rate of loss occurred in transportation between the factory and the factory that fills cans milk . Several actions were taken to resolve problems that resulted in dented cans and the first two months of phase control it was found that the smaller losses calculated target resulting in a saving for the company. The short time of implementa-tion of the Improve phase did not allow a more detailed a ...

Staphylococcus is one of the more important causes of the called Foodborne Disease(FD), being that from the 40 species described from genus, the more important is Staphylococcus aureus. During years believed that the S. aureus was the only specie from genus able to produce enterotoxins, responsable for the clinical frame in humans, but latest studies report the isolation of other species both positive coagulase (PC) as negative with enterotoxigenic potential. The symptoms of this intoxication appear after a short period of incubation (2-6 hours) and usually characterized by nausea, vomits, abdominal ache, diarrhea, and rarely is fatal. For the toxin to be formed in food is necessary that bacteria population to be at least 105 UFC/g, being that such toxins characterized by presenting great resistance front of gastrointestinal proteases and of homemade termical treatment. Among the main foods that might carry the microorganism, the milk and its derivatives have highlights. The contamination of the product might happen as from the milk from cows with clinical and/or subclinical mastitis, as the Staphylococcus genus is one of the main agents etiologic from this disease, equipments utensils badly sanitized equipments and utensils and from the manipulators. The control of these factors configures as fundamental condition for the achievement of a safe, quality product, which doesn’t offer risk to the consumers
