Poultry nutrition and the challenges associated with the residues of antibiotics in poultry meat

Duration of the project

01.02.2019. - 30.09.2019.

Countries and institutions involved in the project

Lithuanian University of Health Sciences
University of Hohenheim
Institute of Food Safety, Animal Health and Environment BIOR

Aim of the project

Management and hygienic conditions are the main keys to produce poultry healthy meat with good quality. During the rearing of the animals many things can happen which may result in an impairment of the health of the animals. Here, diseases caused by bacteria are of main importance as they are treated with antibiotics. The most critical points are that antibiotics are widely used in poultry production and that most of these antibiotics are also used in human medicine. There the incidence of multi-resistant bacteria is continuously increasing and many people believe that this is mainly caused by the excessive use of antibiotics in animal production. Despite the use of antibiotics in animal production is continuously decreasing the incidence of multi-resistant bacteria in humans is still increasing. This development is also important for zoonotic bacteria like Salmonella and Campylobacter. This problem may, at least partly, be overcome by the use of phytogenic feed additives.

The aim of the proposed project is thus to elucidate the actual incidence of antibiotic residues in the countries of the project partners (Lithuania, Germany, Latvia). This knowledge is of interest as there are distinct differences in the management of the production.

Main activities of the project

The main activity of the project is to organize research visits to compare the production situation in the participating countries and to get an inside into the relevance of antibiotic resistant bacteria in poultry meat.

In the frame of the project, research visits will be organized in Germany, Lithuania and Latvia. The main objective is to exchange the knowledge between the researchers from the foreign countries and the researchers from the host institution. This helps to better understand the current situation in poultry meat production and the impact of antibiotic residues in poultry meat.
