Colostrum is heat-treated to kill CAE at lower temps than pastuerization. It's 60C (140F) for 60 minutes NOT 115 F. 115F is not going to be adequate.
This is how I do it:
2 saucepans
glass pint jar
Thermos
3 digital food thermometers
metal spoon
2 saucepans full of water. In one saucepan, put a pint jar of colostrum & enough water to be even with the colostrum level in the jar. Put a thermometer in both pans of water and the other in the colostrum.
Heat until the colostrum is 140F. Fill the Thermos with 140F water to get the Thermos suface to the right temp, then pour out the water, pour in the colostrum, and close it up tight. Wrap the thermos up in a bunch of blankets or a featherbed.
An hour later, the colostrum should still be around 138F, with most pathogens killed but the IGgs okay.
Heating to 145F will cause loss of the IGgs and colostrum that is heated until it curdles or clumps is worthless.
Cow colostrum for a Johnnes-free herd is a good substitute and I've had good luck with cow colostrum from clean vaccinated herds.
