The levels of lactogenic activity in the serum of rabbits during pregnancy and early lactation have been determined. The accuracy and sensitivity of the radioreceptor assay used were increased by several technical improvements. Lactogenic activity remained low throughout pregnancy and increased at parturition; the highest values were reached on day 5 of lactation. No lactogenic activity was detected in placental extracts of rabbits, suggesting that the lactogenic activity measured in the serum is solely of pituitary origin. These results are discussed in relation to the main stages of development of rabbit mammary glands.
