摘要:

A125I-RIA for progesterone determination in cow skim milk, unskimmed milk and blood plasma was developed. Owing to its specificity, accuracy and easy management, it offers itself especially for routine work. First experience has been gained in field studies on fertility control of cows. Even early as one estrus cycle after insemination, non-pregnant cows can be discerned from presumably pregnant ones with a high degree of certainly. This renders possible the desirable soon reinsemination of such cattle. Insemination outside the estrus cycle was found to be one reason for supposed fertility disturbances.
