Management of necrotic enteritis must be considered along with any holistic management of coccidiosis and litter hygiene to subclinically guarantee preimmunity to the flick must be considered.
We need to control necrotic enteritis because the mucus produced from the pathogenesis of this infection is an adequate substrate for the survival of coccidia proliferation in poultry.
I always advise in my practice an excellent feed grade antibiotics and ciccidiostat to check mate the incidences if necrotic enteritis and coccidiosis in vivo.
As for the litter, the risk if iocydt build up comes from poor litter management that create conducive microenvironment for the build up of infective oocytes which are usually in the surroundings of waterers and feeders.
We need to minimize the level of oocyst risk in these regions by using friendly animal welfare products to absorb excess water contamination around the stated risk regions to slow down the proliferation of oocytes and minimize outbreak, but sustain preimmunity for the flocks.
A few of these nanotechnology friendly environmental products must be synergized with good feed grade antibiotics and cocci diostant to put coccidiosis outbreak on hold in continuous broiler production.

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.
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.
