| Molecular genetics is an additional tool which provides information for the detection and exploitation of genes or chromosomal regions with large influence on economic traits. This comes from the development of dense maps of linkage disequilibrium among genetic markers for many livestock species. Although each type of genetic marker has advantages and disadvantages, the only polymorphisms with enough density to meet important requirements for gene mapping are the Single Nucleotide Polymorphisms Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2013 |
| The Red Sindhi breed is an important genetic resource to be preserved and used in tropical conditions. Some studies have shown small effective population size and high coefficient of inbreeding. These aspects show increased risks of loss of genetic diversity, impairing possible genetic gains to be achieved with selection, and even increasing the risk of future extinction of the breed. The following partner institutions worked on the project: Embrapa Dairy Cattle, Embrapa Tropical Semi-Arid, Emep Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2012 |
| 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 |
| The last decades' expansion of açaí palm cultivated areas in the Amazon was significantly high, it being the source of new jobs and income opportunities for the local population. Even though, the participation of the açaí fruit in the region's agribusiness is rather inexpressive when compared to the volume of fruit production in Brazil.

| This project proposes to develop selected pure lineages of maternal traits for high reproduction performance, weight gain, longevity and functional structure: selected pure lineages of terminal paternal traits for high performance, weight gain, food conversion and meat quality; and to define usage strategies to optimize genetic material (crossbreeding to form matrices and slaughter animals) with this material's cost reduction to producers. The strategy is to develop technical cooperation contrac Status: Completed Start date: Wed Sep 01 00:00:00 GMT-03:00 2010 |
| 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 action plans include technical cooperation activities with educational and international research institutions and the affiliation of Brazil Status: Completed Start date: Sat Sep 01 00:00:00 GMT-03:00 2012 |
| 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 |
| One of the largest livestock problems in Southern Brazil has been the scantiness of varieties of forage species more adapted to this region. In addition, due to global warming and the demand for increased productivity with reduced use of inputs, there is a need of studies on germplasm tolerance to abiotic stresses such as drought, and the evaluation of symbiotic organisms to promote biological nitrogen fixation in grasses. Thus, this project aimed to develop improved populations of some of the m Status: Completed Start date: Sun Jan 01 00:00:00 GMT-03:00 2012 |
| 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.
