Abstract
This study was conducted in two parts. First part consisted of survey conducted through questionnaire to analyse the scenario regarding induction of parturition in bovines of Himachal Pradesh and second was a clinical study to record the clinical efficacy of four different parturition induction treatment protocols in advance pregnant cows. Overall, 24 pregnant cows (6 in each treatment protocols) suffering from cervico-vaginal prolapse and/or recumbency were induced calving using these protocols. These included 1; Dexamethasone, 2; PGF2α, 3; Dexamethasone + PGF2α in combination and 4; Dexamethasone + PGF2α + Valethamate Bromide + Diethylstilbestrol combination. Clinical findings were recorded which included response time from induction to parturition, postpartum reproductive parameters viz peak milk yield and first postpartum estrus and clinical complications like dystocia, retention of placenta post-induction. Blood samples were collected from cows at three stages viz; prior to induction treatment, just immediately after calving and 12 hrs post-calving and were analysed for hormonal and hematological profile.
Questionnaire analysis revealed that Dexamethasone, PGF2α and Valethamate Bromide combination was the most preferred treatment followed with combination of Dexamethasone and PGF2α by veterinarians, whereas, majority of veterinary pharmacists used later combination in field veterinary institutions. Use of Oxytocin in combinations was also reported by some pharmacists.
In present clinical study, although there was no difference in time taken from treatment to calving between different protocols (p>0.05), administration of Dexamethasone alone appeared comparatively the best. Post-partum complications were recorded in all the protocols used in this study. No difference was found in post-partum parameters between present induced and previous normal calving. Similarly there was no difference in hormonal or haematological profile between different protocols, however, cortisol levels decreased (P>0.05) 12 hrs post-calving when Dexamethasone alone was used for parturition induction.
