| 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 ...

| Productivity and forage quality of elephantgrass (Pennisetum purpureum) are directly affected by weed interference. The difficulty of control of these species is one of the main barriers to production and use of the forage as feedstock, as well as to the production of biomass for energy use. Despite the great progress in agro-ecological weed control techniques, herbicides are still indispensable. Thus, the rational use practices of these products should be improved in order to produce quality fo Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of Status: Completed Start date: Mon Jun 01 00:00:00 GMT-03:00 2015 |
| Biological control of the cattle tick through entomopathogenic nematodes by cadaver insect technique 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 Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| Pastures of Cynodon spp. and elephantgrass ( Pennisetum purpureum Schum.) have their productivity and forage quality directly affected by weed interference. The difficulty of controlling weeds is one of the main obstacles to growing and using these forage crops as an input in animal feeding, as well as in the production of elephantgrass biomass for energy use. Despite the progress in agroecological weed control techniques, herbicides are still indispensable, especially in crops on ... Status: Completed Start date: Sat Jul 01 00:00:00 GMT-03:00 2017 |

| Cattle tick parasitism causes losses of three billion dollars a year in Brazil. The main factor behind this is errors made in combating ticks, leading to the selection and proliferation of populations resistant to commercial acaricides. In addition to this problem, there is a demand for sustainable control strategies. Biological control using entomopathogenic nematodes (EPNs), a line of research conducted at Embrapa Dairy Cattle, represents a promising alternative. Recent research has developed Status: Completed Start date: Thu Jul 01 00:00:00 GMT-03:00 2021 |
| 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 |
| Mastitis, a disease that affects dairy herds worldwide and causes huge economic losses to the Brazilian dairy sector has the Staphylococcus aureus bacteria as one of the major etiologic agents. S. aureus is an infectious pathogen, which can be isolated from clinical infections, but is most often associated with chronic and subclinical mastitis, with an augmentation of the somatic cell count (SCC) in milk. This pathogen has several virulence factors, which are important in the bac Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014 |
| 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 |
