Abstract

The aim of this study was to increase bovine pregnancy rate by intra-vaginal biostimulation penis like device (PLD). A total of 336 heifers/cows were AI, in which PLD was used in 193 animals. Animals were grouped as A (only AI) and B (PLD after AI). The overall pregnancy rate was 70.0%. Pregnancy rate in group B was significantly (P=0.004) higher than that of group A. Cows of >7.5 years old is showed lower pregnancy rate in group A, but higher in group B. The heifers were showed more responsive to PLD than others parity. The parity 5 or more in group B was responded to PLD and showed higher pregnancy rate than that of group A. It was found that age was significantly positive correlation parity whereas significantly negative correlation with breed. It is concluded that PLD will increased the pregnancy rate of cows through biostimulation on vagina.
