New Info on Milk Replacers - Scary!

[Southern by choice]

Johnes Information Center posted some information about CMR's.
CMR's are Calf Milk Replacers.
I am posting this here as many use replacers and this may or may not pertain to the replacers you use for goats/sheep.

Viable MAP found in calf milk replacer

@Baymule do you think this should be cross posted in sheep section?
@farmerjan What about cattle section? Since this is about CMR's

 

[farmerjan]

Why am I not surprised. OH this is safe....blah, blah, blah. It certainly couldn't hurt to post in the cattle and sheep sections. There are alot of people that will use calf milk replacer for other species. I've done it. So how do you go about finding which ones are tested clean? And really, since it is supposed to be by direct contact with the cow and infected feces that the calf comes in contact with while sucking the cow, this sure blows that theory all out of the water.

"Johne’s disease (Paratuberculosis), cause: Mycobacterium avium subsp. Paratuberculosis (MAP)
How do sheep and goats get infected? Grazing MAP contaminated pastures and eating and/or drinking contaminated feed, water, or milk. Kids and lambs are more susceptible that adults. Cattle, sheep and goats can infect each other. How do humans get infected? Eating or drinking contaminated raw milk, uncooked meat, and unpasteurized dairy products. What are the animal symptoms? First signs may not appear until years after the onset of the infection. Signs include progressive loss of weight and condition despite good appetite, bottle jaw, and depression. Disease may be misdiagnosed as caseous lymphadenitis, ovine progressive pneumonia, chronic malnutrition, or internal parasitism. What are the human symptoms? Diarrhea and weight loss, it is associated with, or known as, Crohn’s disease in humans."

Powdered milk I guess isn't as treated as one would think I guess. This is really sad. Maybe this is why we are seeing more Johnes positive animals out there.

The worst part is studies in Europe have shown that whole milk off the shelves- pastuerized milk- from the grocery... had 25% having MAP.

from the JDS page:
CONCLUSIONS
Viable MAP were detected in 24 (28.9%) of 83 CMR samples collected at US dairy farms; 12 were positive by PMS-culture, 17 by PMS-phage assay, and 5 samples were positive by both of these tests. A further 2 CMR samples tested positive for MAP DNA by IS900 qPCR. The presence of viable MAP in CMR was significantly associated with higher total bacterial counts, but with none of the other microbiological parameters. This is the first report of viable MAP in CMR, but not the first report of viable MAP in powdered milk products. The source of the viable MAP detected cannot be verified, whether pre- or postprocessing contamination. It is unknown if the quantity of MAP detected in CMR would be sufficient to cause infection of a calf. However, the prospect that MAP has survived the manufacture of dried milk and whey-based products, which are destined for consumption by food animals could have far-reaching potential consequences; further testing of CMR collected directly at manufacturing sites using the PMS and liquid culture approach described above is warranted to verify our findings. The broader food safety implications of detecting viable MAP in this type of dried dairy product are not insignificant given that powdered infant formulae is consumed by young babies with immature immune systems.

You quoted the conclusions- is there a point?

 

[greybeard]

Yes. Easier to get to the crux of the results.
It's why the researchers always include a conclusion to begin with.

 

[Baymule]

Wow, so you have an orphan calf, lamb, kid, and you go buy milk replacer and expose your animal to a disease.

Yes, this should be cross posted.

There are studies that I have archived somewhere done throughout Europe about Crohns and MAP.
They are much tougher on MAP outside the US from what I have read.
