Haematological profiles play a key role in diagnosis of array of reproductive disorders. Postpartum lactating anestrous Ongole cows were treated with estrus and ovulation hormonal protocols Heatsynch (Group A) and G6G (Group B) and haematological analysis was done following estrus induction. The mean of haemoglobin level was ±, ± and ±, ± g/dl on day of selection (0 day), on day of induced estrus in Heatsynch and G6G groups, respectively. The mean PCV was ±, ± and ±, ± per cent on day of selection (0 day), on day of induced estrus in Heatsynch and G6G groups, respectively. The mean level of PCV was statistically significant () between conceived and non-conceived cows, in both the treatment groups | Haematological profile of postpartum anestrous ongole cows treated with hormonal protocols
