In previous projects, Embrapa Dairy cattle developed nanostructured intramammary formulations of mastitis, which show potential therapeutic use in the treatment of bovine keratoconjunctivitis. Infectious bovine keratoconjunctivitis is a contagious disease that affects the eyes of cattle of all age groups, mainly calves, caused by Moraxella bovis. The disease is rarely fatal, but production losses are high. The costs caused by this disease involve weight loss, falling milk production and

Family farming is an economically important segment nationwide, but has many weaknesses of social and technological order. Parallel to this, concerns about the negative environmental impacts of agriculture, livestock and forestry are getting increasingly important on the agenda of society, and the use of inadequate agricultural practices is one of the main causes of degradation of cultivated areas. Given the growing worldwide demand for food, fiber, wood and biofuels, and the consequent need for

The project was conducted in order to identify and evaluate alternatives to produce genetically modified embryos and, subsequently, genetically modified ruminant animals, by identifying methods or procedures that enable the production of ruminant transgenic embryos in a more efficient way, reducing time and costs. Such procedures, associated with the insertion of genes of interest, may allow the generation of genetically modified animals capable of producing recombinant proteins important for an

Grassland intensification strategies such as fertilization and irrigation can be used to shorten the period required for recovery of paddocks under rotational management and thus to increase the productivity. In rotational stocking grazing, the definition of the resting and grazing periods of the paddocks, besides determining the total number of paddocks, exerts a great influence on the quantity and quality of the forage produced. The post-grazing residue, determined by the grazing period and th

Milk production systems in Brazil are based, for the most part, on the use of tropical grass pastures as the main source of nutrients for animals. Keeping high levels of pasture-based milk production depends on the following factors: supply of forage in quantity and quality, maximum duration of the grazing season, rational use of energy, protein and mineral supplements, and definition of management strategy that aims at productivity by area. Therefore, intensive pasture management results in for

Improper handling for tick control favors the proliferation of resistant populations. In addition, there is a growing demand for minimum use of chemicals to control pests, in order to preserve the environment and ensure free waste food. In this context, biological control using entomopathogenic nematodes may represent a promising alternative and, therefore, constitute line of research that has been conducted at Embrapa Dairy Cattle. In this stage of the survey, performed in partnership with UFRR

What is the cost of producing one liter of milk in Brazil? Any answer between R$ 0.10 and R$ 1.70 is true. But, also, it is not essentially true. This occurs for two major reasons, both resulting from a lack of standardization. The first reason is that there is an immense amount of production systems in Brazil, from the South to the North. Therefore, in Brazil, rural properties are not standardized, as in Europe, the USA, Canada and Oceania. Each farm is a farm. The second reason is that there i

The breeding programs of Dairy Gir, Guzerat, Red Sindhi and Girolando breeds are conducted at Embrapa Dairy Cattle in work integrated with the respective breeders' associations, as follows: ABCGIL (Brazilian Association of Dairy Gir Breeders), CBMG2/ACGB (Brazilian Center of Guzerat Genetic Breeding / Association of Guzerat and Girolando Breeders Brazil), ABCSindi (Brazilian Association of Red Sindhi Breeders) and Girolando Association. It also includes the participation of the following institu

Brazil is the fifth largest producer of milk in the world with 35 billion liters produced in 2015. However, Brazilian dairy farmers still need improve milk quality and reduce production costs. One of the major limiting factors to increase the efficiency and competitiveness of milk production in Brazil is the management of dairy farms. In this context, Embrapa Gado de Leite developed, in partnership with the Central Cooperative of Rural Producers of Minas Gerais -(Cooperativa Central dos Produtor
