title: Radioimmunoassay of progesterone in cow milk.
abstract: Fertilization checks in dairy cattle performed by estimation of progesterone in milk require a simple technique, the use of a sample taken independently of milking procedure and a simple management of the results. The laboratory equipped with a sample processor and pipetting device, high throughput counter for 125iodine and a tabletop computer can analyse about 1000 samples of fat-free milk in one day. The results are used for computer management of reproduction and veterinary service in farms with 600 to 2000 cows.
