The identification of animals with more efficiency in feed utilization is one of the alternatives to overcome the challenges as increased production costs, increased consumer awareness regarding food safety, animal welfare and environmental impacts of the agriculture and livestock. As feeding expenses account for the main cost of livestock activity, differences among animals in converting diet to beef and milk are of great relevance. Animals that use feed more efficiently need to consume less to

Development programs aimed at increasing production, improve milk quality and assist genetic selection of livestock are strategic initiatives to modernize the dairy chain in Brazil. Farmers, mostly family-scale, need special guidance to access technological information and training programs to increase production and improve productivity of the dairy herd. In addition, action plans and strategies to improve milk quality are essential in order to promote their inclusion in the formal dairy market

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. In this proje

Dairy cattle breeds of European origin stand out for their high productive and reproductive efficiency in temperate climates, but they usually do not present this efficiency in tropical climate, in conditions such as high temperature and humidity, high incidence of endo and ectoparasites and low level of management. On the contrary, Zebu breeds in selection programs to increase milk production are naturally adapted to such conditions, that is, they produce well in less sophisticated managerial p

Bovine tick parasitism is a determinant of estimated losses of US $ 3.4 billion annually in Brazil. Much of these losses are due to mistakes made in the controlling attempts. The three main mistakes made are the use of an inappropriate acaricide at the wrong time and in the wrong way. In view of this situation, Embrapa Dairy Cattle implemented the acaricide effectiveness testing, a free service based on the determination of the most suitable product for application in each property, based on sam

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

Selection for desirable bovine phenotypes has been practiced since the domestication of cattle, which occurred approximately 10,000 years ago. This process of domestication has brought about a marked change in behavioral and morphological characteristics in the subspecies and, together with the development of breeds and genetic breeding programs, has given rise to the enormous variety of patterns and racial types known today. Since then, traditional breeding tools, based on quantitative theory,

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

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
