Samuel Rochell (University of Arkansas) explained the results of his research on coccidiosis vaccination and its impact on nutrient digestibility, during IPPE 2018 in Atlanta, USA.
Dear Samuel
In India Coccidiosis is most significant disease in breeding as well as in commercial layer and broiler farms.Regular preventive and curative treatment with several available coccidiostats are used to contain the disease.Coccidiosis Vaccination is still not practiced.
My question to you is to understand the effectiveness of this preventive method and the cost benefit if any. We are trying to import coccidiosis vaccine covering the prevalent coccidia species in India.
Your valuable guidance will help us take right commercial decision.
DR S S CHABBRA INDIA
In India now broiler breeders, layer breeders and commercial layers are being kept in cages hence coccidiosis in such birds have reduced to a greater extent. In case of commercial broilers this coccidiosis problem still exists where ever litter management is poor and ventilation is bad. Early observation in the flock for coccidiosis. If observed and medication with vitA is given. One can control this issue to some extent.
How effective is the coccidiosis vaccination as? Will it help in prevention and develop immunity against prevalent coccidiosis strains in our country and the cost involved?
In caged birds cocci disease chances r rara If rearing of caged bird is done on floor then vaccination at day one is beneficial In broilers coccidiostat in feed prevents cocci litter management plays a very important role in cocci control. Moisture in the litter must not exceed 30%.
We can reduce the cocci incidences by maintaining a very good farm environment with perfect disinfection which is suitable to kill oocysts, because coccidiosis is a purely managemental failure disease which will be spread through oocysts. Oocysts can survive years in the soil and there are multiple hosts/vectors for their survival, so it's always better to maintain better farm management conditions along with feeding coccidiostats like ionophores or others and administering effective vaccines according to the local infectious Eimeria species.
Surender Reddy Of course, you have right. But the sporulated oocysts are not simple to destroy. Most of the broiler breeder consider the oocysts are easy to destroy and this idea is wrong. Maybe a protocol for sporulated oocyst disinfection is welcome here.
Ing. Dragan Ionut in external environment farmers usually use disinfectant such as phenolic compound however these products are toxic. Alternative control mesures will be welcome
There is a simple solution of Cocci Vac spray at day one is best solution to protect Broiler breeders.We have complete control of Cocci in broiler breeder through Cocci Vac D in Pakistan.
Cocci Vac D is distributed by I.C.I in Pakistan.I do not remember that i have seen any Coccidiosis case during last 10 to 15 years in well manage farms heaving strict Bio security measure as we can not depend 100% on vaccines.Mostly anti coccidiosis medicines having some after effects.
Thank you.
I agree with Dr. M. Mazhar Khan. The best control measure is to vaccinate the birds between 1-5 days of age with Cocci Vac. We have used this method effectively since 1976 in all the farms I have supervised. I still would like some research to be done on the source of the Coccidia that infects birds in newly built poultry units which have been thoroughly disinfected with all the equipment and paraphernalia.
However if you experiencean outbreak, I suggest you use a coccidiocide to kill the adult coccidia and repeat the treatment before the newly sporulated oocysts reproduce to break the cycle. This would preclude the development of resistant coccidia.
The best control measure is to vaccinate the birds between 1-8 days of age with Cocci Vac and even late and this is the best one at breeder layer level and even one can do it late up to 3 wk my personal exp. and if the once done at the Farm next time that Farm can get 50% dose of the vaccine... further, some other exp has done for half dose for the birds and then with litter management it can be spread and introduce to rest of the houses at the farm ... Thanks
I agree with the expert opinion. In severe outbreaks caused by resistant oocysts I have succeeded in controlling by removing the infected litter, and liberal application of hydrated lime on the litter floor along with coccidial drugs in water feed.
Give an antibiotic for cocci at 8 day and weekly ones doing flame gun for disposal of oocytes from the droppings. That's the prevention method for coccidiosis.
Digestion of oocytes can only take place when proteolytic enzymes are produced. This is about as from 21st day. Anti coccidia medication strategy should start at about 18th day and not 8th day. Medication as a strategy should take place where bio securities are in deep suspect. The idea is to break the cycle, especially at syngamy stage.
Here in India, 99% of broilers are reared in deep litter, where good management has a very important role to play. Mostly first 2 months of layer and breeder are also done in deep litter. Here chances are more to get cocci. Vaccination does their part but if we maintain dry litter, we could avoid it significantly. If we only manage good biosecurity and do proper air/temp, water and litter management we can avoid almost every such disease. Something infected feed also plays a little role but it's rare.
After usage of cocci vac D through spray on day old or on fourth day can we use Amrpolium if yes than why we use the said vaccine in layer broiler Breeder etc
In Pakistan, we usually use cocci vaccines in Broiler breeders at day old age on hatchery through spray method. I have observed an outbreak of E.TENELLA at the age of 8th wk to 12 wks even at the 13th week in a flock with this ici vaccine I'm facing this TENELLA infection since last 6 yrs. For layer in cages we dont need cocci vaccination but for floor layers we can go for vaccination for broilers coccidiostats r the best solution to control cocci.
Dear colleagues! In my opinion, there is no universal scheme for prophylactics of coccidiosis for all farms. Each farm has its own scheme. And in each case there are individual dependencies. We have experience in the prevention of coccidiosis for 20 years, and very rarely there are similar situations. Therefore in each case it is necessary to understand separately. For example, I am convinced that vaccination is not suitable for integrated farms, but it can be suitable for small ones. Deep litter in my opinion is not a good solution for general sanitation on the farm. But in any case, everything must be looked at from different angles.
