Blood minerals level in relation to various stages of estrous was determined in 35 Friesian and jersey cows. The experimental animals were divided in to following 4 groups 1. Friesian cows non cyclic. 2. Friesian cows repeat breeder 3. Jersey cows non-cyclic 4. Jersey cows repeat breeder. Blood serum was analyzed for calcium, In organic phosphorus and magnesium. The mean values of calcium 1.96, 2.68, 1.89 and 2.67 m mols-1 lit and of phosphorus were 1.46, 1.57, 1.42 and 1.50 m mols-1 lit in four above groups respectively. The mean concentration of magnesium was 0.80, 1.03, 0.84 and 0.99 m mols-1 lit respectively. The concentration of calcium and inorganic phosphorus was significantly higher in repeat breeder (2, 4 groups) than in non cyclic cows (1, 3 group). The calcium and phosphorus ratio (Ca : P) was significantly wider \lower 1.34:1, 1.33:1 in non-cyclic Friesian and Jersey cows than 1.70:1, 1.78:1 in repeat breeder Friesian and. Jersey cows respectively.
