Ensuring a promising conception rate of non-descript zebu cows maybe an appropriate approach for cattle development and rural livelihood enhancement in Bangladesh. The study was designed to determine the factors affecting conception rate of non-descript local zebu cattle (n = 307) under Artificial Insemination (AI) program using frozen semen. The demographic factors were recorded by interviewing the farmers. All cows were examined for pregnancy diagnosis by rectal palpation of genital tract at 60-80 days post AI. The overall conception rate of zebu cows was 57.7% and the required service per conception was 2.19. The conception rate in cows that received 2nd and 3rd service was significantly (p1.5 L milk?day had significantly (p<0.05) higher conception rate than others. It is concluded that conception rate of non-descript indigenous zebu cows is influenced by postpartum insemination interval, interval from estrus to AI, parity, feeding practice, milk yield and age of zebu cows.
