| 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 Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2008 |
| Bovine mastitis is considered the main disease of dairy herds in the world, causing the greatest economic losses to the dairy sector. In Brazil, production losses caused by mastitis are estimated between 12 and 15%, accounting to more than three billion liters of milk per year. In addition, mastitis poses risks to public health, due to the possibility of contamination of milk with antibiotic residues or with microorganisms and their toxins. The high frequency of mastitis pathogens resistant to t Status: Completed Start date: Wed Jul 01 00:00:00 GMT-03:00 2015 |
| This project articulates, in conjunction with the Brazilian Association of Holstein Cattle Breeders, dairy cooperatives and artificial insemination centers, the restructuring of the management of zootechnical data bases in order to carry out studies on new methodological procedures, essential for the modernization the current genetic evaluation system.

| The productivity indices of dairy farming in Brazil are low when compared to countries with technologically advanced dairy farming. Productivity can be significantly improved through the use of animals with higher genetic value for milk production and appropriate management techniques. Worldwide, the Holstein breed is predominant for milk production, being also the most used in Brazil, both as a pure breed and in crosses, as a contribution to the development of the Girolando breed.

| Currently, the stockbreeding production systems have been becoming more sustainable and efficient, making Brazil the world's largest meat producer, grounded in undeniable quality. The country has the world's most diversified stockbreeding system, which is able to compete in international markets with distinguished products, especially buffalo originated ones (for instance their low cholesterol meat), guaranteeing these products a privileged position in demanding markets. Raising buffaloes, today Status: Completed Start date: Wed Oct 01 00:00:00 GMT-03:00 2008 |
| Despite the growth in the production and productivity rates of dairy farming in Brazil, the globalization of the economy, the fluctuations in domestic and foreign food prices, the changing feeding habits of the population, with the growing interest in functional foods as well as foods from agroecological or organic production systems, coupled with the strong demand for genetically improved and adapted animals, are relevant factors that have challenged research and development agencies in proposi Status: Completed Start date: Mon Sep 01 00:00:00 GMT-03:00 2008 |
| Pasture as an exclusive feeding source accounts for almost 90% of the beef consumed in Brazil and for most of the nearly 35 billion liters of milk produced annually in the country. It is estimated today that, in Brazil, grasses of the genus Brachiaria are cultivated in approximately 84 million hectares. In Brazil, the most cultivated species of Brachiaria are B. decumbens, B. brizantha, B. humidicola and B. ruziziensis. With the increasing agricult ...

| Pastures assume a prominent position in the Brazilian agricultural scenario, covering about three quarters of the cultivated area nationwide. In addition to the physical aspect, pastures are the main feeding source for the Brazilian herd. Pastures account for almost 90% of the beef consumed in Brazil and for most of the 21 billion liters of milk produced annually in the country. It is estimated today that in Brazil grasses of the genus Brachiaria are cultivated in approximately 84 millio Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008 |
| In the last century, the wide use of Guzerá breed in crossbreeding led to the expressive reduction of their effective population size, to worrying numbers. Due to its adaptation to diverse environmental conditions, its potential for dual-purpose production (i.e. meat and milk), and its risk of extinction, in 1991, this breed was included by FAO (Food and Agriculture Organization of the United Nations) in the list of genetic resources to be preserved. In view of this, and due to the demand for br ... Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008 |
| The dairy activity in Brazil has undergone extensive changes. If, on the one hand, the industry tends more and more to value items associated with the quality of milk, such as fat, protein, total milk solids, etc., the prices paid or the incentives applied are arbitrary or defined based upon the financial return arising from one unit of the product. On the other hand, the dairy farmer does not know if the received incentive value, when it exists, is interesting from the point of view of returnin Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008 |
