Information flows and environments in business contexts: the meat sector case of Salmanca/Spain

Organizational environments are related to hierarchic levels existing in a determined organization, and they influence in the formal and informal flows origin and in their monitoring and/or extinction. Informational environments are a result of organizational environments, of which focus is information and knowledge. Information flows are a fundamental element to informational environments, in a way that there´s no informational environments if there´s no information flows. Informational flows are natural reflections from their environments, in terms of content and in the way they occur. This qualitative and quantitative research was developed in three stages, in a way to allow the comprehension of the phenomena related to information and knowledge environments and information flows that occur in the meat sector from the Province of Salamanca, Spain. We used Laurence Bardin´s ‘Analysis of Content’, more specifically the ‘Categorical Analysis’ technique to data analysis. As data collection procedure we accomplished a field research, applying a questionnaire as an intentional sample of the meat industries segment from the Province of Salamanca, Spain. From data tabulation and analysis, we infer that information environments and flows are relevant to these companies business development, as well as we emphasized the need of information and knowledge management deployment, in a way to insure organizational processes quality, industrial chain production and companies competition to conquer potential markets.

Modelling energy utilization in poultry

Models of daily energy requirement can help to establish better and more profitable feeding programs for poultry. Studies have been conducted at UNESP-Jaboticabal-Brazil with the aim of studying energy utilization in broiler breeders, laying hens, and broilers, and to establish metabolisable energy requirement models. The factorial approach was used to partition the energy requirements into maintenance, growth, and production components. The resulting models consider body weight, weight gain, egg production, and environmental temperature for the determination of the energy requirements of poultry. These models were evaluated in performance trials and provided good estimates. Therefore, they can be used to establish nutritional programs. The aim of this chapter is to describe the development of these models and to outline the results of our studies at UNESP.

Salmonela em carcaça de aves

The genus Salmonella was characterized in 1885. It is divided into two species and six subspecies or subgenera. Belonging to the family Enterobacteriaceae is composed of Gram-negative rods, usually producing mobile gas from glucose, except in those serovars S. gallinarum and S. Pullorum. Salmonela is one of the biggest problems in public health for its wide occurrence in humans and in animals, where they occupy the center of the epidemiology of enteric salmonelosis. These are responsible for significant rates of morbidity and mortality. Several outbreaks of food transmitted diseases are described involving meat birds. Sources of salmonela in broiler chicks infected stem, feed and farm environment. Currently, S. enteritidis and S. typhimurium are the two most prevalent serovars. In this context, the sum is increased resistance to antimicrobial drugs is including the latest generation of its indiscriminate use in veterinary medicine. This fact represents risk to human and animal health. New strategies have been adopted by the Brazilian poultry industry to control salmonela in broilers, but the contamination by this pathogen is still present in slaughterhouses putting public health at risk

Análise higiênico-sanitária de produtos cárneos comercializados na cidade de Botucatu

Brazil is one of the largest producers of animal protein. In 2010, the production of meat (beef, pork and poultry) was estimated at 24.5 million tons and 75% was consumed in the country. The meat is a primary source of water and fat and contains between 20% and 35% protein, providing all essential amino acids and several micronutrients and vitamins. Due to the large consumption of this food, its quality is extremely important and the research of some indicators microorganism become essential in order to ensure the hygienic and sanitary quality, indicating contamination of fecal origin, with the possible presence of pathogens or to identify food spoilage. Thus, the aim of study was to determine the microbiological quality of 90 samples handled meat products and pre- prepared marketed in Botucatu city, according to the parameters required by ANVISA (RDC  12, 2001). Among the samples analyzed, all of them were negative for Staphylococcus coagulase positive and were within the limit allowed by ANVISA for the Clostridium sulfite reducer (up to 3 x 103 CFU/ g). The presence of Salmonella was confirmed in only one sample (1.1%), against to the legal parameters. About thermotolerant coliforms, 54.4% of the samples were outside the acceptable limit by law (up to 5 x 103 MPN/g). Therefore, the presence of these microorganisms indicates inadequate hygiene conditions of foodhandlers and equipment used in the, which are considered inadequate for consumption

Stability of a Lipase Extracted from Seeds of Pachira aquatica in Commercial Detergents and Application Tests in Poultry Wastewater Pretreatment and Fat Particle Hydrolysis

A protein extract containing a plant lipase from oleaginous seeds of Pachira aquatica was tested using soybean oil, wastewater from a poultry processing plant, and beef fat particles as substrate. The hydrolysis experiments were carried out at a temperature of 40°C, an incubation time of 90 minutes, and pH 8.0-9.0. The enzyme had the best stability at pH 9.0 and showed good stability in the alkaline range. It was found that P. aquatica lipase was stable in the presence of some commercial laundry detergent formulations, and it retained full activity up to 0.35% in hydrogen peroxide, despite losing activity at higher concentrations. Concerning wastewater, the lipase increased free fatty acids release by 7.4 times and promoted the hydrolysis of approximately 10% of the fats, suggesting that it could be included in a pretreatment stage, especially for vegetable oil degradation.
