ABSTRACT

Cyclicity and conception rate after induction protocol in infertile dry cows was assessed in terms of the induction of oestrus in anoestrus cows and conception in repeat breeder’s cows in the study. There were four anoestrous and two repeat breeder cows in G-1 out of them two anoestrus became cyclic, one repeater animal conceived after treatment. Where as in G-2, three anoestrus and three repeat breeder animals given induction protocol where two anoestrous cows became cyclic and two repeaters conceived. The analysis of data revealed higher response in G-2 as compared to G-1 (66.67 Vs. 50 %, respectively) with the higher conception rate (50 Vs. 33.33 %, respectively). It indicates better fertility response in G-2 as compared to G-1.
