Poultry Infectious Diseases Control

From June 18th until 21st, 2019; Sverdlovskiy, Pedigree Poultry Breeding Unit, held another seminar in Yekaterinburg for mid-level veterinarians under the title “Sverdlovsk Production and Scientific Systems named after G.P. Gracheva”.

The seminar was devoted to a relevant topic, Control of Infectious Diseases in Poultry. Drawing up effective preventive vaccination schemes in poultry farming.

As in previous Sverdlovskiy seminars, the event was educational in nature and aimed at training mid-level specialists, primarily veterinarians. Therefore, the practical focus of the reports and presentations was highly significant; for speakers shared their practical experiences with the audience. Nonetheless important, was the informal socializing between participants during their free time.

The list of participants included representatives of the poultry farms in Russia and neighboring countries including Ukraine, Tajikistan, and Kazakhstan.

Speakers' speeches covered a wide range of issues in the field of preventive vaccination:
  • Vaccination methods and programs,
  • Bacterial diagnosis and antibiotic use strategies,
  • Poultry infectious diseases and measures for their prevention,
  • Features of reading and interpretation of diagnostic test systems, …etc

The report of the representative of InterKlin LLC, Andrey Chernikov, was devoted to poultry farming equipment, namely, cold and hot fog generators, various pressure washers that allow to perform high-quality disinfection of poultry houses and, therefore, prevent the birds’ infectious diseases.

The speech by Natalia Vinokurova, head of the poultry faming department at “Virumbio”, was practically useful. Her presentation was dedicated to reading and interpreting the results on IDEXX sets. The relevance of this report is associated with the complexity of the diagnostic system interpretation, with the need to consider a lot of details during the test recognition. The correctness of assignment of the preventive or therapeutic measures depends on the diagnostic success, which means the health of the birds and the success of the entire enterprise.

The report of the consultant expert of BPR Sverdlovsky LLC, Vladimir Volchkov, revealed the urgent problems of the birds’ health - those problems that may be faced by the poultry farms. These are the diseases of viral and bacterial etiology and their prevention. According to the expert, minimization of the risk of infectious diseases is possible “by observing preventive measures, by maintaining the breeding and genetic stock of your poultry, and by optimal feeding”.

Maria Orlova, a leading veterinarian at BPR Sverdlovsky LLC, spoke about the sanation measures, that will provide the necessary biosecurity for the poultry enterprises. Among such measures are the limitation for vehicles and/or people access to the production territory; and strict monitoring the cleanliness of the premises.

Several reports were devoted directly to the poultry diseases, such as the infectious bronchitis, Gumboro disease, enterococcosis, salmonellosis, …etc., and their preventive vaccination.

“The previous seminar brought together at one venue, specialists who are responsible for poultry health and for the prevention of infectious diseases,” commented Ivan Grachev, deputy director of marketing at BPR Sverdlovsky LLC.. “The topic of infectious diseases and preventive vaccination is always acute, and nowhere else should you keep an eye on the topic as here, since the epizootic situation is changing rapidly, viruses are mutating and previous vaccines may no longer be effective. The success of an enterprise depends on the quality of poultry health prevention; moreover, healthy products are a socially significant, strategic task in any country. I am glad that all the speeches at our seminar were of a high level, and have provided the audience with up-to-date information.”.

For an in-depth familiarization with seminar’s topics, we offer a few flash interviews with participants. Those interviewers noted the practical usefulness of the seminar and discussed the relevant topics, for example, the rejection of antibiotics in the poultry farming.

Vladimir Ivanovich Volchkov
Consultant Expert, BPR Sverdlovsky

– What message did you want to convey to your audience with your speech?

– My report addresses the problems that poultry farms can may face. These are issues of bird diseases of viral and bacterial etiology. In my speech, I wanted to communicate that it is possible to minimize the risk of diseases by compliance of all preventive measures, by maintaining the breeding and genetics of your poultry; and by optimal feeding. That is how we work at Sverdlovskiy PPBU and get optimal results across generations. Such healthy birds are sold to different regions and farms.

Adding, here at this seminar, there are representatives of farms to which BPR Sverdlovsky supplies its breeding products. These are the farms from the regions of Russia and other countries including Tajikistan, Uzbekistan, and Kazakhstan. The distribution area for the Sverdlovskiy PPBU chickens is very large. This poultry production unit is characterized by the epizootic well-being. The most demanded productive crossings are sold like hot cakes and are very successful among the buyers.

– What impressed you at the seminar?

– I was impressed with the competence of the people who work in the poultry industry companies, in the vaccine manufacturing companies. We heard consistent, prepared reports that today are relevant at present for veterinarians at different farms.

– Do you have any wishes to the participants of the conference?

– Wishfully, that all that was proposed here in the reports, be applied on farms. I usually tell everyone: when working with the crossings from Sverdlovskiy PPBU, follow their recommendations very carefully. If you do it, you will achieve success!

Alexey Alekseevich Gnatyuk
Key-Client Account Manager, Vic Trading House

– How relevant is the topic of infectious disease prevention?

– This topic will always be relevant, and especially in our country. Why? Because one of the features of Russian poultry farming is its large-scale involvement, density, and a lot of poultry.

– What will you apply from what you have heard?

– People are interested in practically applied theory. What works in theory, is different than what works in practice. A lot of such practical details were voiced at the conference, and that is very useful for work. Despite the fact that I visit a lot of various events and seminars, I have heard a lot of new things here, clarified and noted them. Wishing for the organizers to stay on such tracks!

– The impressions of the seminar are very good. Much new on the topic of infectious diseases. It was helpful to listen to the vaccine manufacturers themselves. Reports on preventive measures, for example, enterprise sanitation procedures, were also useful.

Ilya Vadimovich Kazantsev
Technical Consultant, Ph.D. in Veterinary Sciences, Elanko Rus LLC

– Tell us about your speech?

– I presented two Elanko products that are currently available in the Russian market: the vaccine against Gumboro and salmonellosis diseases. Under the current epizootic situation, it is impossible for poultry to live without immunization. I have presented in my report vaccines that will effectively protect the birds, demonstrated the documental vaccine-usage evidence and its advantages over the competitive products.

– How relevant is the topic of preventive vaccination?

– Vaccination is one of the cornerstones in poultry farming, thanks to which we can effectively protect our birds and provide consumers with safe food products.

- How does antibiotic therapy affect end-product safety for consumers?

– The uncontrolled use of antibiotics is very bad. Why? Because there is a group of antibiotics in veterinary medicine that often intersect with those antibiotics used in human medicine. Accordingly, we must use such drugs that would not harm humans. This is first. Secondly, unfortunately growing up poultry today without any antibiotics is possible; but it is very difficult. And that will be for a high price for the product, due to the fact that there will be a natural loss of poultry, since we cannot now provide either sterile feed nor sterile conditions. In any case, the bacteria will come and the poultry will die. Accordingly, we need to support it periodically. Each antibiotic has its own run-out period recommended by the manufacturer. As a consequence, if we comply with the requirements for dosage and run-out period, then, in my opinion, it is quite possible to use these drugs.

– Any wishes for the organizers?

– I would like to have more poultry raising colleagues, preferably, to gather more poultry farms representatives. This is new knowledge, new communication

Alexander Sergeevich Marukhnenko
Veterinarian, BPR Sverdlovsky

– What did you like at the seminar?

– The most interesting thing in other speeches is prevention vaccination and interpretation of EIA test systems. I think it is the most pressing issue, not only for me, but also for other veterinarians. I would, also, like to mention the first speaker; who told about infectious diseases. The topic is interesting and very important, given the epizootic situation in the country and the world.

– What is currently the epizootic situation?

– It is rather challenging. This is due to the fact that the virus mutates constantly. A clinical picture is blurry nowadays, if we compare the clinical findings of infectious diseases with those that were found 10-15-20 years ago. As a rule, any disease described in a book, doesn’t coincide with the picture that we see at the workplace. Therefore, it is important to keep an eye open and constantly monitor changes in the pathology.

– How far do vaccines keep up with changing viruses?

– The preventive vaccination is quite effective, and one strain can be used for several serotypes of viruses, so vaccines are functional.

– How critical is the use of antibiotics?

– Europe is now trying to get away from antibiotics. And in Russia, as I understand it, there is the same tendency. At our production venue, at BPR Sverdlovsky, we are gradually shifting away from antibiotic therapy, in favor towards the usage of probiotics and organic acids.

My wishes to the participants is good luck, success in hard work!

Natalia Vinokurova
Head of Poultry Farming Department, Virumbio

– What did you come to the seminar with?

– I came to the seminar to read a report on the topic of "Readings and Interpretation of IDEXX Test System". This topic is always relevant, since the EIA diagnostics is very popular at poultry farms. But, unfortunately, there are just few places where it is possible to learn the EIA reaction formulation and readings. So, the veterinarians have to learn to read the test systems in practice. Therefore, we widely introduce trainings in readings and interpretation. This is relevant for the mid-level doctors, as a rule, the young specialists who are just starting their work path. In my speech, I will touch upon the topic of the test system quality, reasons for trusting them, ways of best practical use, some points you should pay attention to when using test systems. I also draw attention to the practical issues during the reaction interpretation. Two types of specialists deal with test systems - a veterinarian and a laboratory assistant, where each has his/her own specifics. We cover all these issues.

– Tell us about your company.

– IDEXX presents a wide range of test systems for the diagnostics of not only poultry diseases, but also, animal diseases. These are the high-quality systems, and many people put them into practice. IDEXX was the first company in the world that developed test systems. Back in the 60s, the company transferred from human test systems to disease diagnostic systems for animals and poultry. Those test systems are made in America and Europe.

– What are your impressions of the seminar?

– The seminar covers various topics relating to poultry operations, feeding, and health control. The program is very eventful, the seminar is competently organized. It is good that the organizers always focus on training veterinarians. The training sessions are at a very high level. And, of course, there is always an interest in listening to what new things are in the field of poultry health. Have an idea about other’s experience.

– What did you mainly like?

– There are interesting topics relating to the vaccines and salmonellosis. An interesting report was presented in relation to the poultry immunology.

Maria Andreevna Orlova
Leading Veterinarian, BPR Sverdlovsky

– What is the main idea you wanted to pass on in your presentation?

– My report was about "Bio-protection of poultry farms, vaccination of manufacturing buildings". The key to the success of any poultry farm is the enterprise’s biosecurity; that is, how the company is organized, where it is located and what are the requirements for the personnel, service, and transportion. If all these things are observed, then many diseases and the passing on of infection can be avoided.

– What did you like at the seminar?

– I really liked the report of Natalia Vinokurova about test systems, because, in fact, the examination can’t always be correctly interpreted. It is necessary to have one’s experience. Natalia’s report was very informative. I, also, liked the report of Stanislav Rybak, which was interesting in content and presentation.

– How relevant is the topic of diseases and preventive vaccination? And how far, is it possible, to avoid the antibiotic therapy?

– In European countries, antibiotics in poultry farming is already prohibited. They, already, have certain methods developed there; ways of working without antibiotics, for example, they use the acidifiers. We are still on the way to this approach. We don’t have such strict control yet. However, we strive to follow the same path in abandonment of antibiotics, use some developments in practice, set experiments, use acidifiers, …etc.; and support the intestinal health of poultry.

The topic of infectious diseases has always been relevant, as long as, I have been working. Such diseases as the Newcastle disease, infectious bronchitis, …etc. have always been, are and will be available in the world. At present, they talk a lot about the avian flu, that someone is already vaccinating against it, someone is not. However, there is an avian flu problem, and it is relevant. For this purpose, biosecurity is required, so that transportation is processed, and we are calm and secure when a vehicle arrives to the enterprise. Just any vehicle should not arrive to the enterprise, just any person cannot walk-in, because you can bring a virus on yourself, on your clothes, or on your hair.

– Any wishes to the participants?

– We have to gather and exchange experience more often, because you can’t read all these things in books.

Tatyana Yurievna Linichenko
Veterinarian, Volzhskaya Poultry Farm CJSC

– What are your impressions of the seminar, organization of the event?

– I really liked the organization! The organizers were doing great! Everything is thought out – the meeting, food, accommodation. Everything is convenient and comfortable. And, of course, the seminar was useful and relevant. We received a lot of information and made conclusions. I liked the report of Ivashkina, the most. It was capacious, and informative.

– Will you apply anything in a real-case scenario at your farm?

– I’m taking back the theoretical knowledge from the seminar to the farm. There, we will discuss at the general council meeting what and how to implement. Maybe we’ll use something. It should be noted that each factory, as a rule, has its own vaccination system that depends on the site, gas contamination of the territory, and water quality. In vaccination, everything is purely individual.

– What are your wishes to the organizers?

– As for the subject, I think, it will be better to have less advertising and more information about diseases. More detailed description of the diseases. That is, I would like to have more detailed information on the diseases.

Alena Alekseevna Ignatieva
Veterinarian, Volzhskaya Poultry Farm CJSC

– What are your impressions of the seminar, organization of the event?

– Everything is fine, the organization is just wonderful. As for the reports, I can indicate what I liked the most. These are the reports by Markelova N.N., Ivashkina L.N., Vinokurova N.F., and Rybak S. I really liked these reports due to its practical focus, relevance, and possibility of practical application.

– What are your wishes to the organizers? Perhaps you would like to listen to a particular topic at other seminars or something else?

– If we talk about veterinary medicine, I would like to hear to the reports and developments relating to Newcastle disease; about vaccination, revaccination, the best methods and the titers used. In more detail, I would like to get acquainted with information on antibiotics: when and how to use them and whether, it is possible to, dispense with them at all. Also, what is better to use: probiotics, or acidifiers, and to what extent? I would like to have a more detailed study on these issues.

– Svetlana, please, share your impressions! What presentations were relevant? What will you definitely use back at home?

- I would like to thank the organizers for the invitation and hearty welcome, everything was comfortable and cozy. We obtained a lot of useful information, including in the takeaways; namely, the booklets. We will consider and apply all the information at our workplace.

Our factory (Zhas Kanat – 2006) is engaged in egg production, and the topic “Disease Prevention” is always relevant.

– What did you particularly like? Maybe you can specify certain presentations?

– Yesterday, Orlova Maria had a speech, she talked about enterprise security in a very accessible and understandable manner.

– Any wishes for the organizers?

– Many thanks for the invitations and gained experience!

Abdusamad Mavlonov

– What presentations were useful for you?

– Those that were devoted to poultry infectious diseases, such as, infectious bronchitis, and Newcastle disease, seemed most useful.

– Will you introduce something from what you heard at your farm?

– We will probably use everything that I learnt and got here at our Simurg poultry farm. We purchase parental flocks from Sverdlovskiy PPBU, therefore, of course, we listen to all the recommendations of the experts from Sverdlovskiy PPBU.
