Fat percentage and milk progesterone level were observed to be highly conerlated both in co and buffalo milk. The progesterone level in first-milk and full milk varied with fat percentage. Progesterone level in milk of pregnant cows and buffaloes wwas significantly higher as compared to non pregnant animals. On the basis of progesterone level in milk pregnancy could be succesfully diagnosed. In non pregnent animals the success rate of diagnosis was 100 percent on 20th day after inseminatin in both the species.
