| Selection for desirable phenotypes has been practiced in cattle since their domestication approximately 10,000 years ago. This process, alongside breed development and genetic improvement programs, has led to the vast diversity of cattle breeds known today. Traditional breeding methods, grounded in quantitative theory, have facilitated continuous genetic gains in most economically important traits. However, until recently, selection has been conducted without knowledge of the specific genes infl Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2019 |
| 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 Status: Completed Start date: Thu Sep 01 00:00:00 GMT-03:00 2011 |
| The Minas Gerais State Network of Biotechnology for Agriculture (RMBA) includes Embrapa Maize & Sorghum (Sete Lagoas), Embrapa Dairy Cattle (Juiz de Fora), Federal University of Viçosa (UFV), Federal University of Lavras (UFLA), Federal University of Uberlândia (UFU), Veterinary College of the Federal University of Minas Gerais (EV / UFMG), Minas Gerais Agricultural Research Corporation (EPAMIG) and René Rachou Research Institute (Fiocruz Minas). The strategic objective of RMBA is the technologi ... Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2008 |
| The increase in productivity in dairy farming will be essential to ensure increases in the production and supply of milk and milk products to meet the world's growing population. Appropriate technologies should be developed and adopted to enable increased productivity in a sustainable way, ensuring greater milk production with reduced number of animals and farming area. The efficient use of dietary nutrients is one of the premises of sustainable production systems, since their inefficient use no Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014 |
| 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 |
| Losses caused by the parasitism by ticks in cattle are estimated at 3.24 billion dollars annually in Brazil, largely due to procedural errors, such as the systematic and often inappropriate use of acaricides, resulting in selection and proliferation of populations of acaricide-resistant ticks. In addition, there is a growing demand for new alternatives in pest control, aiming at minimum use of chemicals, in order to preserve the environment and ensure residue-free food. In this context, biologic Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014 |
| The gross value of livestock production in Brazil in 2019 was estimated at R$ 213.9 billion. In the ranking of products, in first and second place were beef (R$ 101.5 billion) and milk (R$ 49.8 billion), respectively. Brazil as an exponent in the production of food of animal origin has the health of beef and dairy herds as a strategic asset for the country. In this regard, the existence of national animal health programs is essential for maintaining and improving the health of cattle herds.

| Since Brazil has a strong prospect of becoming a major exporter of dairy products, the production chain of milk needs to prepare to overcome obstacles such as non-tariff barriers related to food safety and quality assurance. Thus, this project aimed to gather information and develop methodologies for addressing such a challenge. One of the goals was the physicochemical and microbiological characterization of four dairy products (Minas Standard cheese, curd cheese, condensed milk, and whey powder Status: Completed Start date: Tue Nov 01 00:00:00 GMT-03:00 2011 |
| 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 ...

| The development of the immune response in animals is quite complex and its modulation is a potential field for the maintenance of health condition of the herds. The control of the main diseases affecting animal production is made with the use of acaricides, antihelmintics and antibiotics that constitute risks to animal, human and environmental health. In this context new approaches to maintaining the health of livestock must be developed in order to minimize these risks and at the same time meet Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2019 |
