Ok, now I've read it for the second time, I've gone ahead and bookmarked this post. So grateful Bob.OK, Let's Revisit the Chicks & Medicated Feed vs Medication
First to put one misconception to bed. One in which I too was caught up.
After a feed review where I evaluated 11 different Medicated Chick feeds, there are NO non-pathogenic strains of coccidia in use. That is incorrect and I apologize for repeating that bad information. Let me say that again so it is clear.
THERE ARE NO FEEDS WITH NON-PATHOGENIC COCCIDIA
Of the 11 feeds I evaluated:
So what does this mean.
- 9 use Amprolium (Corid)
- 1 uses Monensin (Cobon)
- 1 claims that Diatomaceous Earth in the feed will kill coccidia
DO NOT USE MEDICATED FEED AND MEDICATION AT THE SAME TIME
Amprolium imitates Thiamine (vitamin b1) which is essential for Coccidia to grow. When Coccidia ingest Amprolium instead of Thiamine they experience Thiamine deficiency and starve from malnutrition. Your chicks also need Thiamine.
IMPORTANT: Because of this Amprolium has a very narrow margin for error. Overdosing can lead to hemorrhagic diathesis (spontaneous bleeding) and death.
DO NOT EVER TREAT CHICKS THAT ARE ON MEDICATED FEED WITH AMPROLIUM
The medicated feed is already dosed correctly for your chicks. The use of medicated feed alone is effective at the prevention of coccidiosis.
However, if you chicks are already showing symptoms of coccidiosis you should use a NON-MEDICATED feed and MEDICATE them. This will enable you to use a higher dose of Amprolium in order to get on top of the infection.
Treatment
So what is the prescribed treatment for coccidiosis?
The Poultry DVM recommends a therapeutic dose of 0.024% in water to reach therapeutic levels. If you are utilizing Corid 9.6% liquid solution, that would be 2 teaspoons per gallon of water. Treat for a minimum of 5 and up to 7 days. This must be their only source of water for those days. No rain puddles etc.
After the initial dose taper to 0.012% for another 5 to 7 days. That would be 1 teaspoon per gallon of water.
If you are going to use Medicated Feed at the end of the second treatment you can switch them to medicated feed and you should be fine.
If you are NOT going to use medicated feed, you need to switch to a final tapering dose of 0.006% for 7 days. That would be ½ teaspoon per gallon.
Storage
Chicks are not going to drink a lot of water. How long can I store this stuff? Any medicated water which the chicks have not consumed in 24 hours should be discarded. Prepared solutions may be stored in clean, closed, and labeled containers for up to 3 days at temperatures between 41°-77° F or 5°-25° C.
