Abstract

A new method for milk sample collection and storage, based on a dried milk sampling technique, is proposed. The method includes application of a whole milk sample to a porous membrane followed by drying. One hundred whole milk samples (dried and liquid) taken on day 21 post insemination were analysed for progesterone by ELISA and results for both dried and liquid samples were well correlated (r=0.911). Milk progesterone ELISA accuracy for pregnancy diagnosis in cows was 87%.
