Description The present experiment was undertaken to estimate the level of certain major (Ca, P, Ca : P and Mg) and trace (Cu, Co, Fe and Zn) elements in plasma of cyclic and anestrus Sahiwal heifers and also evaluate the efficacy of mineral supplementation alone and combination of GnRH with PGF2α and Progesterone administration for the induction of estrus in anestrus heifers. A total of 30 Sahiwal heifers (6 cyclic and 24 anestrus heifers) were selected from the Bull Mother Experiment Farm, Anjora, Durg. The animals were maintained in farm managemental condition. All the heifers were of more than 33 months of age. The animals did not show any sign of estrus even after achieving 33 months of age, were classified as “pubertal anestrus” heifers. The blood plasma mineral (major and trace) level was estimated and compared between cyclic and anestrus groups. The results showed that there was non-significant difference in plasma level of major elements (Ca, P, Ca : P and Mg) between cyclic (9.50 ± 0.31mg/dl, 4.74 ± 0.48 mg/dl, 2.11 ± 0.24 and 1.68 ± 0.009 mg/dl) and anestrus (9.10 ± 0.25 mg/dl, 4.44 ± 0.47 mg/dl, 2.34 ± 0.176 and 1.68 ± 0.005 mg/dl) heifers, respectively. The plasma level of trace element Co and Zn showed non-significant difference between cyclic and anestrus Sahiwal heifers. Among the trace elements the level of Fe and Cu found to be significantly (P < 0.05) higher in cyclic than anestrus Sahiwal heifers. Mineral supplementation alone, along with GnRH administration and combination of GnRH with PGF2α administration resulted estrus induction in 16.66 %, 33.33 % and 33.33 %, respectively, during observation after the completion of treatment in anestrus Sahiwal heifers. Progesterone administration in a single dose and in multiple dose (10 dose) resulted estrus induction in 80% and 60% of anestrus Sahiwal heifers, respectively.
