Oestrus Induction and Fertility Response in Post Partum Anoestrus Buffaloes using CIDR Alone or in Combination with Antioxidants

The present study was carried out to study the effect of ControlledInternal Drug Releasing Device (CIDR-B) with and without antioxidants (vitamin E & selenium) on oestrus induction response and oxidative stress parameters in postpartum anoestrus buffaloes located in different villages of R. S. Pura areas of Jammu district. A total of 18 postpartum anoestrus buffaloes were equally divided into three groups with 6 buffaloes in each group. Group I animals were kept as control, Group II animals were treated with CIDR protocol and Group III animals were treated with CIDR protocol and were given two intramuscular injection of vit. E-Care-Se (50 mg α-tocopherol acetate and 1.5 mg selenium per ml, Vetcare, Banglore) at the dose rate of 1ml/50 kg BWT. on day 0 and day 7, respectively. Oestrus induction response was 100% in treated animals and onset of oestrus occured within 70.50±6.38 h and 68.33±3.12 h and mean duration of oestrus was 22.33±1.14 h and 20.75±1.30 h in Group II and III, respectively. The pregnancy rate was 0.00%, 50% and 83.33% in Group I, II and III respectively. Among the oxidative stress parameter, a significant decrease in lipid peroxidation (LPO) and superoxide dismutase (SOD) level along with significant increase in catalase (CAT) and glutathione peroxidase (GPx) level was observed by treating post partum anoestrus buffaloes with CIDR protocol either alone or in combination with vitamin E and Selenium.
