We were in a drought before this but the weekend all this come about, it flooded.
Contamination and lack of sanitation is a big issue with the problem but I have been told that the Coccodia are species specific and do not cross over.TCRanch":ykda5lq5 said:zirlottkim":ykda5lq5 said:These were weaned heifer calves that I had problems with recently. The other two times was spring, very young calves and seems it was wet conditions at the time. Another cattleman in the area had issues back then also. No one that I know of locally is having trouble now. Except me.Stocker Steve":ykda5lq5 said:How common is this?
How much is caused by calving in wet conditions?
We had one outbreak in one pasture during the drought & weren't the only ones around here. A lot of seasoned ranchers said it was because all the birds (including geese, ducks, etc) had flocked to what's left of the ponds & contaminated them. Our vet didn't rule that out as a possibility. Fortunately ours was a mild case and I mixed Corid pellets in with their cubes, cleared it right up.

If you do feed minerals with something that does control coccidiosis and the cows are the only ones to eat it for the months prior to calving, there are less ozotes shed by the cows for the calves to ingest. So, minerals with whatever are an indirect preventative in the calves. That is the strategy recommended on sheep and it works great. Sort of the clean ground theory. Like the old man said, "The best way to get out of trouble is to never get into it".

Just to be clear. Transmission is not cow to calf, calf to calf. There is not "direct transmission". The oocysts are excreted in the manure and are not infective until they sporulate and develop into the sporozoite. They sporulate on the substrate the animals are housed in. The host has to ingest the sporozoite to become infected.
ozotes. Not familiar with that term. Do you mean oocysts?
This is an extremely large group of protozoans. They are species specific with exceptions.
I had a supposedly knowledgeable cow man look at my calves when they first got sick. He said I had a Vitamin B deficiency. So on his advice I gave the sickest a shot of Vitamin B. Next day I sent fecal samples to vet and coccidiosis was diognosed. After reading your post, I went to Corid site and read this:How CORID worksNesikep":3anso4tw said:I think it was while reading the Corid literature that I found this protozoan requires a certain B vitamin to live/reproduce.. It also has an incubation time of 4-6 weeks, which is the exact age my calves get it, if they do.. seems as though every year I have a couple.. they look and feel awful, but unlike bacterial scours, don't go off milk and I've never had a loss. I did learn to not keep heifers that have had it really badly as it damages their gut permanantly, and this isn't evident while they're on milk, so they look like nice animals at weaning and fall apart over the next winter and aren't efficient feed converters. Corid works by blocking the absorption of the B vitamin.
I had some eureka moments regarding what calves eat, etc but I've forgotten it now.

Structurally, CORID mimics thiamin (Vitamin B1) which is required by coccidia for normal growth and reproduction. When coccidia ingest CORID, they experience thiamin deficiency and starve from malnutrition. I think I was shooting myself in the foot.

Margonme":1zpke6wq said:Rumensen and bovatec are not parasiticides. Meaning they do not kill the coccidia. They act to enhance the calves absorption of electrolytes, nutrients, etc. They also enhance the digestive environment thus promoting better health and immune response.
