There aren't bacteria in MY colostrum.
Why do we try to deny things that we don't want to believe? A national study of colostrum revealed this about "total plate counts":
- fresh samples 33% above 100,000 cfu/ml
- frozen samples 39% above 100,000 cfu/ml
- refrigerated samples 77% above 100,000 cfu/ml
- fresh samples 12% above 1,000,000 cfu/ml
- frozen samples 11% above 1,000,000 cfu/ml
- refrigerated samples 38% above 1,000,000 cfu/ml
Now you can see why the first two questions I ask when trouble shooting scours problems on a farm is, "When was the last time you cultured "as-fed" colostrum samples for bacteria?" and "May I see the results?"
When was the last time you sampled "as-fed" colostrum and had it cultured for bacteria.
