ABSTRACT
The study aimed to enhance the rate of pregnancy of water buffalo by intra-vaginal bio-stimulation after AI. The study was conducted from August 2022 to July 2023 in the selected coastal area of Bangladesh. Sums of 75 adult female buffaloes were selected. Age, breed, parity, and others were recorded during selection. The animals were grouped into three experimental groups (group A: natural service, group B: conduct AI only, group C: using penis-like device-PLD following AI) and each group consisted of 25 animals. It was found that the average rate of pregnancy was 46.6%. The rate pregnancy in group A (64.0%) was higher than that of other groups. However, among the AI, the rate of pregnancy in group C (44.0%) was comparatively higher than that of group B (32%). This study also found that the pregnancy rate had a significant (P<0.05) result on parity, reproductive health, and previous records of calving difficulties. It could be concluded that the use of a penis-like device helps to raise the rate of pregnancy of cows subsequent to AI. However, the PLD must be modified to make the device more convenient and useful in buffalo cows. In further study, it is suggested to modify the device with the clitoral massage.
