Contributing factors to repeat breeding and postpartum anestrus and pregnancy rate subsequent to hormonal intervention in crossbred dairy cows

A cross-sectional study was conducted from January to July 2021 determine the prevalence and contributing factors repeat breeding (RB) postpartum anestrus (PPA) in crossbred dairy cattle central highland of Ethiopia. Furthermore; a retrospective used collect data on occurrence RB PPA associated risk factors. The pregnancy rate determined by rectal palpation day 60 after hormonal therapy using double PGF2α GnRH combination with PGF2α. (Ovsynch). 33.85% 30.73%, respectively. Body condition score, parity, milk yield, herd size, abortion, mastitis all revealed statistically significant association (p < 0.05) PPA. Cows previous history abortion were 2.58 times at than those without. Similarly, cows 2.63 more that didn’t encounter disease. Previously aborted older greater parity numbers 2.89 1.23 affected PPA, Moreover, endometritis retained fetal membrane showed (p<0.05) anestrus. rates treated + (Ovsynch) 41.46% 29.17%, It is concluded research area influenced body condition, daily yield cow. Reproductive health problems including membranes, endometritis, Although use or has resumed cyclicity cows, are yet low. Hence, utilizes detailed assay profiles reproductive-related blood metabolites should be done.
