Combating Coccidiosis

We all know that coccidiosis is a common and significant disease of commercial poultry farms all around the world. This disease causes impaired feed efficiency and reduced weight gain, mortality, and increased susceptibility to other diseases including necrotic enteritis.

We also know that elimination of this parasitic disease by common management practices is very difficult, if not impossible. Anti-coccidial drugs have been used for many years in the poultry industry in order to deal with this disease. Development of resistance to drugs and also recent moves toward restricting use of drugs in poultry diets has put pressure on the industry to look for alternatives.

Vaccination is currently an option available to the poultry industry. What do you think of using vaccines to prevent coccidiosis? Do you think that the industry should only use vaccines and terminate use of anti-coccidial drugs? What about a combination of vaccines and drugs?

    When you using a vaccine you are able to know when the pressure in NE or Cocci will be present, that mean that you could using some other solution for prevent this pressure in the same time. It's true that we have a resistance to drugs available, it's why we make some rotation in the production, but please think about also some natural solution, in extract of plants, essential oils and organics acids, a synergy of natural ingredient could help you to target same objective with very similar application price, we working in ABF and organics production since more than 5 years and we see less resistance with Natural products. A good management of breeding is also essential, lighting, temperature, humidity, air pressure, ... are also very important in your success. David -Synergie Eurobec Inc. (info@eurobec.ca)

    Vaccines are the best tool for success at controlling of the coccidiosis, especially adding to rotation programs. We have lots of success in our farm by using the vaccines in rotation programs.

    The safety of the digestive system is important to a chive the equation of the feed due to meat (broiler) or egg (layers and breeders). So the infection or any disorder in the intestinal like coccidiosis which is caused the regressing in the advantages which we aim from the feed.
    In my country we use few kinds of the coccidiostasis like (salinomycin, diclazoril, toltrazoril, amprolium, sulfaquenoxalin, monensine, etc.), but in the last time we find the resistant of the coccidian to the drugs especially Diclazoril.
    But we can contribute the frequent of the coccidian in the one stock to the pad rearing system (bad litter and flour management).

    In my point of view good management practice is the corner stone to compete such a challenge and impact and on the other hand the intermittent sulfa-based therapy and last not the least is the vaccine and i think they are the most reliable and beneficial methods to protect your flock.

    Coccidiosis..it's true that vaccines helps control the coccidiosis but the true control of coccidiosis is the control of supervisor and watchmen in the farm so it's not becoming a relevant diseases.

    This subject is important. In my opinion, using vaccines is the best method to control diseases. But, this depend on the efficiency of vaccination. If there is any body who can tell us his experience in this field, we will be thankful.

    David mentioned the use of natural products. We have been succesfully using a symbiotic combination of patented natural products to successfully elminate vaccines and coccidiastats.

    Anticoccidial drugs are being restricted? This is news for me. Can you provide more details. While vaccines may be helpful in fighting the cocci, they do not restore performance to the same extent the anticoccidials drugs do. And ultimately performance is the end in mind.

  • no-profile-image


    Anticoccidials remain essential for poultry production. The use of vaccine in Europe is only dedicated to high margin/high profit markets (breeders, organic broiler. Vaccine faces issues in term of performance, litter management and costs. Use of anticoccidials remain the long term solution to produce safe, affordable meat and by respecting animal welfare.

    I have seen a flock where there was use of vaccine for some birds and coccidiostat for remaining birds. The inference was, the birds with vaccine were very much protected as compared to birds which were on coccidiostats where there was huge mortality.

    Although anticoccidial drugs makes coccidiosis vaccines breakdown but in case there is early detection of any traces of breakdown, we should not hesitate to administer anticocci drugs.

    Vaccination is good but in case the vaccine fails especially at our farm (in Africa) but immediately we noticed the symptoms of coccidiosis, we administered anticocci.

    Considering the relatively high cost of the vaccine, and the emerging concerns about coccidiostats, residues and their regulation, research has been done on use of probiotics. This can be a cheaper and more effective way to fight coccidiosis.

    Wonder if there is any good method of verifying the immunity of chicks vaccinated against coccidiosis (including E.Necatrix) ..any reliable test such as Elisa...etc???

    Dan McDermott mentioned success with natural products for coccidiosis. Could you please provide details. I currently have about 50 broilers and need help! Thank you!

    I m living in a area where peoples having little sense about the proper hygenic and good managemental practices so if we are suffering such sort of problmes I think herbal/natural ingredients with the help of probiotics will give good assisstance for resolving the coccidiosis problmes. vaccinations are not available in every part and also not a 100% results.

    I think the best ways to control coccidiosis is vaccination

    In Viet Nam, Coccidiosis is always a challenge to poultry farmers. We often use some common anticoccidial like: diclazuzil, totrazuzil, Sulfa but not really effective. Our company is now raising free-range layers without antibiotic as well as minimising of using other other medicines. So, I'm interested in natural products to deal with coccidiosis. Could someone tell me the name of ones. And I'd like to look for in VN. Thanks so much.

    Country like Pakistan we have no restriction for using any kind of medicine in feed regarding coccidiosis, problem is seasonal when the feed material options are limited reasons for necrotic enteritis are frequent,,mycotoxin levels are not on safe side ,cocidiosis become a frequent problem ,so the factors regarding necrotic enteritis should properly controlled.

    @ Dr M Asif raza. Can you explain that in Pakistan there is no problem that you guys are facing regarding coccidiosis?

    I live in Southeastern North Carolina USA (Wilmington Area) and would like to know where I may purchase vaccines for poultry for small flocks (200-400 chickens). It is a major issue for me trying to raise broilers.

    Una buena alternativa es usar Sulfato de cobre a dosis de 0,5 grs por litro de agua de bebida por 2 dias cada 15 dias. En producción 1 dia a la semana en igual dosis. Tambien extracto de granada (Punica granatum) 500 grs de fruta hervir en un litro de agua para 10.000 aves.
