Conference in Kazimierz Dolny

Feed Materials and Additives – Current Requirements

The 28th International Scientific and Technical Conference on “Feed Materials and Additives – Current Requirements” took place between 28 and 29 March 2011 in Kazimierz Dolny on the Vistula. It was organized by the National Research Institute of Animal Production (NRIAP), the National Feed Laboratory in Lublin, and the National Veterinary Research Institute (PIWet – PIB) in Puławy in cooperation with the Lublin Branch of the Polish Academy of Science and the Department of Pharmacology and Toxicology of the Polish Society of Veterinary Sciences.

The conference was opened by the directors of the institutes: Prof. Jędrzej Krupiński (Director of the National Research Institute of Animal Production) and Prof. Tadeusz Wijaszka (Director of the National Veterinary Research Institute). The aim of the conference was to present feed producers, veterinary inspection inspectors and the employees of the Veterinary Hygiene Establishment with the results of research on the monitoring of nutrients, undesirable substances and harmful feed materials, and concerning the evaluation of using feed additives in feed products, taking into consideration current legal requirements. Research workers from the Ukraine and Germany also participated in the conference. The delegation of the employees from the State Scientific Research Control Institute of Veterinary Preparations and Fodder Additives in Lviv was headed by its Director, Prof. Ihor Kotsiumbas. The Institute of Animal Husbandry UAAN in Kharkiv was represented by Sergey Shapovaov Ph.D. Prof. Friedrich Schöne from the Thuringian State Institute of Agriculture (Jena, Germany) also took part in the conference. The Institute of Agriculture in Jena serves as the national reference laboratory in the field of feed additives used in animal nutrition.

Lectures were given by research workers from the National Veterinary Research Institute in Puławy and the National Research Institute of Animal Production, as well as representatives of other national and foreign research establishments (Germany, Ukraine) and institutions which establish “feed law” regulations or supervise their implementation.

One of the key issues was paying attention to new requirements concerning feed materials and feed mixtures as well as feed additives and products that contain them, in terms of safety and quality evaluation, in connection with the coming into force of the Regulation (EC) No 767/2009 of the European Parliament and of the Council on the placing on the market and use of feed and the Commission Implementing Regulations. Particular attention was paid to the evaluation of nutrient tolerances in feed materials and feed mixtures, feed additive tolerances in feed products, and homogeneity of feed products based on the results of proficiency testing and interlaboratory comparisons, monitoring studies in research units, and monitoring studies as part of the official control of feedingstuffs.

Considerable attention was paid to the methods of analysis of nutrients, feed additives, active substances, medicated feeds, undesirable chemical pollutants, and microbial feed materials and feed mixtures. Relevant reports were presented mainly as posters (22 posters).

Consideration was given to threats related to undesirable chemical (e.g. dioxins, mycotoxins) and microbiological pollutants (e.g. Salmonella) and threats associated with feed processing and feed production technology (feed processing aids, cross-contamination). Much attention was given to evaluating the lawful use of feed additives, particularly coccidiostats, in terms of observing the maximum content and the related risk for animals, products of animal origin (cross-contamination) and the environment.

Here are some of the presented papers. Prof. Tadeusz Wijaszka (Director of the National Veterinary Research Institute) discussed issues concerning the official control of feed and animal feed safety. Selected issues associated with the official control of feed additives in the Ukraine were presented by Prof. Ihor Kotsiumbas from the Institute in Lviv. The importance of iodine for humans, iodine additives used in the feeding of farm animals and their effect on the quality of animal products origin were presented by Prof. Friedrich Schöne from the Thuringian Institute of Agriculture. A paper referring to the importance of iodine in human and animal nutrition was presented by Prof. Franciszek Brzóska (National Research Institute of Animal Production), who discussed current monitoring results of iodine content in consumer milk in Poland. A content-rich paper on analysis of threats and risks in the food safety assurance system with consideration of feeds and animal nutrition was given by Prof. Krzysztof Kwiatek (National Veterinary Research Institute). A paper on the official control of feed materials and feed mixtures in 2010 was presented by Dr Jacek Boruta from the General Veterinary Inspectorate (GIW) in Warsaw. Papers were given on the evaluation of nutrient and feed additive tolerances in light of current requirements and the evaluation results of feed homogeneity. It is worth noting some interesting papers concerning the presence of dioxins in domestic feeds (Prof. Jadwiga Pliszczyńska), medicated feeds (Prof. Andrzej Posyniak), coccidiostat use and control under new conditions (Prof. Teresa Szprengier-Juszkiewicz), and control of anabolic drugs in feeds (Barbara Woźniak Ph.D.).

Company offers were presented by representatives of Foss Polska, Aqua Lab, Noack Polen and Lab-Invest. The representatives of these companies also demonstrated their own products in the stalls.

The lectures generated interest in the conference topic, as evidenced by animated discussions and the questions asked. Questions and some problems raised during the conference will be presented in the forthcoming issue of Pasze Przemysłowe (Commercial Feeds). Conclusive answers were not always possible, and some problems will need additional analyses and arrangements to be solved. It is not without significance that the participants were able to meet others interested in the same topics, share experiences, participate in backstage discussions of problems bothering feed producers, laboratory staff at the Veterinary Hygiene Establishment and Veterinary Inspection inspectors. The need to look for new solutions, which are confirmed and substantiated by acknowledged scientific research was emphasized. An opinion was expressed about the need to continue such meetings. The summaries of conference papers and reports were published as conference proceedings and some issues will be presented in the forthcoming issue of Pasze Przemysłowe in the form of a monograph.
