Repeat breeding in cattle inversely affects the profitability of dairy industry by decreasing the conception rate. Selected 18 repeat breeder cows reared under ideal farm conditions and divided them in to three groups of six animals each viz., group I, II and III with four primiparous cows and two second parity cows in each group. The cows in group I were treated with intrauterine preparation containing aqueous solution of povidone iodine (5%w/v) and metronidazole (1%w/v) (Utrodin IU), followed by uterine lavage with 120 mL of normal saline and inseminated them in the oestrus after skipping the first heat. The animals in group II were treated with an IM injection of buserelin acetate (Gynarich) post AI. The cows in group III were treated with both Utrodin IU and Gynarich post AI. The conception rate observed in group I, II and III were 66.67% (4/6 cows), 66.67% (4/6 cows) and 83.33% (5/6 cows), respectively. The results of the study indicated that combined use of intrauterine preparation containing metronidazole and povidone iodine, along with GnRH was more satisfactory than their individual use in improving the conception rate of repeat breeder Frieswal cattle under farm conditions in Kerala.Â
