For obtaining optimum protection from Coccidiosis Vaccine, the companies marketing cocci vaccine must provide detailed literature in local language, so that right from application/ administration of vaccine to completion of 3 to 4 cycles (life) are completed for optimum immunity development.
Most of the mistakes/ deficiencies are made due to lack of knowledge about vaccine application, otherwise, none of the farmer wants to waste expensive cocci vaccine.

Dear Wijaya Saputra
Interesting things have already been said by other bloggers.
1- Regarding your numbers:
Except HH1, excretion peak is completed at 21d of age that is perfectly consistent with the 3rd life cycle of coccidia shredded on the floor.

2- Bloody feces and probably an upsurge of oocysts excretion at 35-37 days of age is often a consequence of a non-homogeneous cocci-vaccine application and/or birds to birds transmission.
Do you manage the 1-d old bird cocci-vaccine at the hatchery?
=> Make sure of the best liquid or gel homogeneity at the application stage.

Brooding management could help to compensate partially non-homogeneous vaccine application.
=> The birds must be confined to a max of half of the house with a set of drinker and feeder lines for at least 10 days with adequate relative humidity and temperature to make a good sporulation condition on brooding paper.
Important: By providing 60% brooding paper coverage below the feeder and water lines would provide the extra feed and water spillage needed to stimulate bird activity and appetite as early as possible. This method may provide the needed coverage to allow progeny vaccine oocysts to remain at the litter surface for ingestion by the bird (low-level oocyst cycling). The removal of the paper is a normal practice has to be completed only after 10 days after vaccination.

- Amprolium Management:
250 ppm of Amprol 50% should be sufficient. It is effective against 1st generation of trophozoites and schizonts and shows peak activity early in day 3 of cycle. As pointed out by Jarred, the administration Amprol, at 15-16 d of age is too early… Non-well infected birds will not have enough life-cycle coccidia to develop their own and efficient immunity. I would complete it between 27-29 days of age.
hope my words will be helpful.

Interesting thoughts of brooding management!

How many birds would you place per square meter for the first 10 days? How many birds will you allow per nipple?

Thanks!

Dear Salak,
This not such how many birds per m2 that is important for brooding…
I guess that 1/3 or a 1/2 free total floor (with sufficient water and feed lines) for animal proximity.
If you do not have enough nipples, you can manage water plate on the brooding paper as the feed supply.
Regards

I am a vet technician, now a master's vet student, I would like to learn more about the topic.

What are the causes of crack eggshell in laying hen?

Dear Dr Abdullah,
Many causes … and not easy to respond without any data about the laying flock.
But except an error, unbalanced or insufficient amount minerals and trace mineral into the feed, an increase of crack eggshell is often a consequence of low intestinal absorption.
Then, we have to investigate the causes of the low efficiency of intestinal absorption: EN symptoms, coccidiosis breaks…
I recommend to use additive will have a positive effects on intestinal integrity (as example butyric acid, MOS, Local antioxydant agent…).

Thank you sir,but sir,we are in serious need of thought about Newcastle disease which is the second most deadly disease affecting poultry in most african Countries particularly Nigeria

Not an expert about this Sorry.
See with your supplier of Newcastle disease vaccine what is the best (most appropriate) practices to complete in African countries conditions (climate, breeds, barn,...).

We have a mesogenic strain of Newcastle disease vaccine called mukteswar strain or R2B vaccine. It is live vaccine with ICP VALUE 1.30 (highly invasive), excellent for birds weighing above 500gms to be given intramuscular or subcutaneous. We inject our breeders and layer birds at 7/8 WEEKS and again just before lay. Excellent results. It works even on the face of outbreak. Orthodox, but it works. It produces nervous lesions in a few birds (1%) an indication it is working. Try it, you will be amazed. New strains of Newcastle claims still need verification.

Sir, in summer we have seen thin eggshell and hairline cracked and dotted on eggshells.
I'm using organic mineral regularly and increased some dose in summer but the problem starts in summer when the temperature is rising. What is the solution?

As for the improvement about eggshell strength, please try Xtract6930 and you will be surprised at the result, it's very consistent. please contact Pancosma if you need samples and explore the reason.

Against egg shell cracked, we had a positive experience with use of vegetal extract named Epatolife containing Schizandra Chinensis, Boswellia Serrta, Arpagophytum Procumbens. Scizandra Chinensis regenerate the epatocities permitting a greater production of bile, improving the intestinal absorption of calcium for less productions of intestinal calcium soap, reducing egg breakage.
