Use of hyaluronidase enzyme for hastening the cervical dilatation in successfully detorted uterine torsion affected buffaloes
Keywords:Bubalus bubalis, buffaloes, cervix, fertility, hyaluronidase, uterine torsion
The successfully detorted uterine torsion buffaloes were either subjected to routine post-detorsion treatment (n=10) or in addition to routine treatment, intracervical hyaluronidase enzyme was administered (10,000 IU; 2.5 ml at each of 3, 6, 9, 12 o’clock position of cervix) immediately post-detorsion (n=10), followed by repeated administration at 6h interval (0, 6, 12, 18 h) till complete cervical dilatation or till 24 h post-detorsion. The time elapsed between successful uterine detorsion to complete cervical dilatation was reduced (P<0.05) in buffaloes subjected to enzyme treatment in comparison to their control counterparts (754.6±114.0 vs. 213.5±33.1 minutes). In buffaloes delivering dead fetus, following intracervical treatment, the interval between detorsion to complete cervical dilatation was reduced (P<0.05) to 240.8±44.0 minutes in comparison to their control counterparts (838.1±126.2 minutes). Moreover, following hyaluronidase treatment, the time interval from detorsion of a buffalo to complete cervical dilatation with respect to degree of uterine torsion was much lower (P<0.05) in treated compared to their control group counterparts having either <180o or ≥180o uterine torsion. The fertility parameters (number of days to first estrus and duration of service period) were improved (P>0.05) in hyaluronidase-treated buffaloes of both the groups (<18 h or ≥18 h duration of torsion) as compared to their control counterparts. Conclusion: Intracervical hyaluronidase treatment hastens the cervical dilatation in successfully detorted uterine torsion affected buffaloes with a subsequent potentially beneficial impact on fertility.
