The presence of enterotoxigenic Staphylococcus and its enterotoxins in milk and dairy products is a concern for industry and government agencies responsible for public health. S. aureus is the species most often associated with outbreaks or cases of staphylococcal food poisoning. As this microorganism is an important pathogen of mastitis in cattle, the udder of the infected animal is one of the main sources of contamination of raw milk. Other species of Staphylococcus hav

Milk is a complex substance that presents different characteristics depending on the management of animal factors. The alizarol test is typically used at collection points, which often generates divergences between the industry and farmers because of faulty results and subjectivities. More refined tests are only accomplished in laboratories when the milk reaches the industry. A very critical problem is the occurrence of Unstable Non-Acid Milk (UNAM), as there are changes in the milk's physical-c

Factors associated with environment and management and those directly related to animals, such as the health of the mammary gland, have major influence on milk quality. In dairy herds, the prevalence of mastitis can easily reach values of 70%, which causes loss of production, alteration in milk composition, increased somatic cell count (SCC) and to a lesser intensity, increased total bacterial count (TBC) in wholesale milk. The objective of the team in this project was to carry out a phase I and

The Experiment Stations of Embrapa Dairy Cattle have a strategic infrastructure for conducting research projects and experiments with direct and practical application of results. Keep livestock (young and adult animals) and infrastructure in the production systems in permanent operation require significant investment in terms of labour and financial funds. In the experiment stations, many factors or variables related to milk production are controlled in order to increase the accuracy of results

The Compost Barn system has the purpose of reducing costs in the implementation and maintenance of animal facilities, improving herd production and sanitary indices, and enabling the correct use of dairy farming organic waste (feces and urine). The system consists of a large covered space for the cows to rest. The floor is covered with sawdust, wood cutting scraps and composted manure. The main objective of Compost Barn is to ensure comfort to the animals and a dry place for them to stay during

The presence of Staphylococcus spp. in milk and milk products is a concern for dairy farmers, industry and government agencies responsible for public health. Because these microorganisms are important pathogens of mastitis, the udder of the infected animal is a major source of contamination of raw milk.

Cattle farming is one of the most important activities of Brazilian agribusiness. Brazil is the world's largest beef exporter, holds the world's largest commercial herd, and is the world's third largest producer and consumer of beef and the world's seventh largest milk producer, with about 4% of the world's total. In spite of its large overall production, Brazilian cattle farming remains low in productivity, indicating a great potential for improvement and expansion of this sector of the economy

Bovine mastitis, which in most cases has S. aureus and S. agalactiae as causal agents, is an important disease in the livestock sector of Brazil due to losses it originates in the milk production chain and derivatives. In particular, S. aureus has a high zoonotic potential and is often associated as a cause of food poisoning outbreaks. Thus, controlling such microorganism in cows suffering from mastitis becomes crucial. However, this is an arduous task, since this bacteri ...

Dairy farming is one of the most important economic activities in the agribusiness of the State of Minas Gerais, which is the largest milk producer in Brazil (28% of production). The dairy production chain is one of the most important in the state, employing labor, generating revenues of around R $ 2.4 billion/year and guaranteeing income for a large part of the population. However, most properties have low productivity due to several factors related to the herd, such as health, genetic potentia
