Never seen the red and gold one shown above...
Any of the 50 IgG usually will say colostrum "supplement"... not Replacer.. anything over 100 says replacer on the pkg.
BUT... better than nothing. They cost about half what the actual 100IgG replacer ones cost... I have never seen a 200IgG replacer on any of the shelves here. I keep one or 2 pkgs... but also keep several qts frozen colostrum from my own cow(s)... in the freezer... Pints and Qts are quicker to thaw...then 1/2 gallons...... NEVER use the microwave... and a qt down the hatch is worth it's weight in gold compared to nothing... I will usually feed a 2nd qt in an hour or 2 after the first one....
A calf does not drink a 1/2 gallon all at once when brand new....
