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.
Thanks for your input and accordingly chicks reared on floor/deep liter should start coccidiostats medication from 18th day onwards instead of day one.
If this is true that it can reduce feed cost to that extent up to first two weeks or 18 days to be precise. Kindly share authentic research data on this point for the larger benefit of poultry industry.

Dr. S.S Chabbra I must add here that date count for baby chicks should start from day of hatch rather than the day of arrival in the farm. Some birds arrive farms up to 5 days after hatch. They survive nutritionally on yolk stalk till feeding starts from the farm. Nowadays nutritional gels are introduced into their boxes by some hatcheries but not all during transportation to the farm. My arguments here is if, for example, baby chicks arrive farm three days after hatch owing to transportation time to the farm. Every date calculation on the farm should be as from three days behind.
Nowadays cocci is a great problem in broiler farm where rare in deep litter system although anticoccidial drugs are used. However with the present of anticoccidial which groups of water-soluble anti cocci drug can be used?
In general, cocci is related to wet litter. In Saudi Arabia RH is around 20% or even less round the year. Here I have seen cocci in broilers in very dry dusty litter.
Cocci is a young age disease. I have seen many outbreaks in layers. It becomes very difficult to treat cocci in laying birds.
Should we consider if coccidia are changing for their survival?

If the litter is very dry, it is better to look at the oocysts not in the feces but in the litter material, and determine whether the oocyst is sporulated, that is, invasive.
I doubt that at a humidity of 20% the oocyst is able to sporulate.
Dr. S.S Chabbra, In order to understand whether to use any drugs for the prevention of cocci on deep bedding, you need to understand how important you are to weight gain and feed conversion, how strong the cocci pressure (OPG), and the invasiveness of the oocysts. After that, you can make a decision

DR JAKARIA AHMED 25% Amprolium plus 25% sulphaquinoxaline is the best combination for now both for prevention and treatment strategies. Originally it was 16.66% Amprolium and 16.66% sulphaquinoxaline combination but the newer combination is owing to current heightened resistance on the side of eimeria stages to coccidiostats
Disinfection of the litter with spray, but i think it would not do more to oocysts, then wat precautionary measures, should we adopt to get rid of oocysts in the litter !
Anjum Naqi
t seems to me that disinfection of the litter will not give the desired effect, since not every disinfectant can destroy the shell of the oocyst, and it is almost impossible to do such treatment in the presence of chickens. Disinfection to remove oocysts from the environment is best done without bedding during the preparation of the chicken coop for colonization. This will reduce the number of oocysts by 3 times, which in turn will reduce invasion in the future and allow the immune system to work without even a subclinical disease. We conducted such an experiment on a livestock of 1.5 million chickens.
Ihave gone through ur findings on how to prevent oocyst in poultry litter thanks for your contributions i sat to wait for new welcome development God bless
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.

For Coccidiosis prevention program can we use (Amprolium/Toltacox alternately ) in water
and ( Sacox/Nimax) in feed simultaneously to avoid risk of coccidiosis, because this farms are high loaded with coccidia as known from outbreaks previous history.
These two way shuttle programs effect on birds or are there any antagonistic reaction?
Dr Charles Ibe
If we rearing in floor-slat shed , can we use (Amprolium/Toltacox alternately ) in water
and ( Sacox/Nimax) in feed simultaneously as prevention of coccidiosis,
Amprolium is a weak coccidiostat if used alone. Toltraziril is a coccidiocide. Use Amprolium in combination with sulphaquinoxaline! Alternate it with another coccidiostat. Sulphur drugs are only for rearing birds. Or use toltraziril to alternate with dicalzuril . Two of them are coccidiocides. I prefer coccidiostats because they give the birds a measure of graded immunity as time goes on. I had not used feed grade anticoccidia. Some one else can give us a clearer picture!
