Description |
Feeding of 0.1, 0.2 and 0.3% triptolide in bait for 5 days in no-choice feeding test to male Rattus rattus (Linnaeus) in laboratory resulted in average per day consumption of 10.76, 20.45 and 22.60 mg/kgbw of triptolide, respectively and 75.92-93.00% acceptance of treated bait over plain bait. No significant effect of triptolide treatment was observed on body weight and reproductive organ weights of rats after 30 days of termination of treatment. The sperm motility and viability in the cauda epididymal fluid of rats treated with 0.2% triptolide was found to be decreased significantly by 80.65 and 75.14%, respectively from that of untreated rats. The major effect of triptolide treatment on sperm morphology was sperm head tail separation which varied from 46.13-53.69% in treated groups of rats. Laboratory breeding revealed 66.67, 100.00 and 33.33% decrease in pregnancy rate of females paired with males treated with 0.1, 0.2 and 0.3% triptolide, respectively. Treatment of poultry farm with 0.005% bromadiolone followed by second treatment with 0.2% triptolide at 15 days interval for 5 days revealed significantly lower rodent population rebuild up (16.30%) than that observed in poultry farm treated only with 0.005% bromadiolone (51.87%). Only 25% of the rats trapped from poultry farm treated with triptolide revealed antifertility effects which may be due to partial recovery in effects after about 60 days of termination of treatment. Present studies suggest the potential of 0.2% triptolide in bait for 5 days in regulating post control population rebuild up of R. rattus in poultry farms. |
