Coccidiosis control methods - Samuel Rochell

Dr. S.S Chabbra

Dear Sirs,

Thank you for your solicitation.

Based on your experience who are the major poultry producers in India?
How do you envision their feather development in the global marketplace?

Kind regards,

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.

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.

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.

Can anybody give a recommendation on how we can manage space after coccivav D vaccination when given around 4th day (post management of vaccination?

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.
