Abstract/ Executive Summary:

Controlled induction of parturition is a very useful tool for managing calving and post-parturition management and successful parturition in dairy farms. In the present study, 12 pregnant buffaloes were treated with dexamethasone in combination with cloprostenol for controlled induction of parturition in Lal Teer Livestock Research and Development Farm, Mymensingh, Bangladesh. The buffaloes were divided into two groups according to their gestation length. The gestation length of buffaloes of group-A was up to 330 days (305-330) and group-B was more than 330 days (331-345). Buffaloes were injected with 6 mL Roxadex and 2 mL Ovuprost intra-muscularly (Roxadex®, Nuvista Pharma Limited, Bangladesh containing 5 mg Dexamethasone sodium phosphate mL^-1 and Ovuprost®, Bayer Animal Health, New Zealand containing 250 μg Cloprostenol sodium mL^-1). Induction of parturition was occurred in all buffaloes in an average time 29.17±3.06 h after the treatment. The duration between treatment and the induction of parturition showed a significant difference (p<0.01) between two groups. Retention of placenta was recorded in 33.33% of animals and the occurrence of dystocia was 25.00%. The viability of newborn (calves) was 91.67% as compared with dead calves 8.33%. It was concluded that dexamethasone in combination with cloprostenol can be used successfully for induction of parturition in buffaloes of Bangladesh although there was a moderate incidence of dystocia and retention of placenta, which needs to be minimized by careful follow up, critical observation and prompt assistance. Further therapeutic trials are needed to minimize the incidence of retention of placenta and dystocia.

Objectives:

To observe the efficacy of Dexamethasone in combination with Cloprostenol in controlled induction of parturition of dairy buffaloes in Bangladesh.
To prescribe steps towards improvement of buffalo breeding

Methodology:

The study was performed on 12 pregnant buffaloes in Lal Teer Livestock Research and Development Farm, Mymensingh, Bangladesh to observe the efficacy of dexamethasone in combination with cloprostenol in controlled induction of parturition of dairy buffaloes in Bangladesh. The buffaloes were divided into two groups according to their gestation length. The gestation length of buffaloes of group A (n = 6) was up to 330 days (305-330) and group B (n = 6) was more than 330 days (331-345). Buffaloes were injected with 6 mL Roxadex and 2 mL Ovuprost intramuscularly (Roxadex®, Nuvista Pharma Limited, Bangladesh containing 5 mg Dexamethasone sodium phosphate mL^-1 and Ovuprost®, Bayer Animal Health, New Zealand containing 250 μg Cloprostenol sodium mL^-1). The number of responsive buffaloes (%), duration of response (h), nature of parturition, viability (%) and sex of new born as well as to their complication (%) (retention of fetal membrane and dystocia) were recorded. Placentas were considered retained if they were not released by 24 h after calving. Independent sample t-test and Pearson’s correlation analysis (Bivariate) were used (with the help of SPSS Statistics version 20) for analysis of data of this study.

Achievement/Findings:

Dexamethasone in combination with cloprostenol could be used for emergency or controlled induction of parturition of buffaloes in Bangladesh with lower incidence of dystocia, retention of fetal membranes and mortality of calves. The optimal dose, regime and route of administration need further investigation. The results of this study would enormously help to develop an intensive system for buffalo production in Bangladesh.
