I normally usep palpation as a way to determine if a cow has settled or not, but I am not very proficient before about 75 to 90 days, the blood test suggests a 90% accuracy in about the 30 day range of conception for less than $3.00 a test.
Opinions?? pros?? cons???
Seems to me it might be worth the cost to get a jump of 45 to 60 day on a rebreed situation, especially if you cannot catch them in a natural heat! and that is not always possible.
