This study aims to investigate the impact of modern management practices on reproduction and pregnancy in crossbred dairy goats (Boer×Local). The goats were maintained at the Mountain Research Centre for Sheep and Goats at the State Agricultural University to develop a dairy goat breed suitable for the climatic conditions and local needs. This research focuses on the effects of estrous synchronization and artificial insemination (AI) on pregnancy rates. In this study, 20 female goats were divided into two groups. Group I was treated with cloprostenol (125 µg) for estrous synchronization, and estrous signs were observed over the course of one week. In Group II, a buck goat was used as a biological stimulator for estrous detection and synchronization (buck effect). Estrous signs were recorded. For AI, frozen semen was obtained from the Maharashtra Goat and Sheep Research and Development Institute in India. Insemination was performed twice at 12 h intervals, and only semen with over 60% progressive motility was used. Pregnancy detection was conducted using ultrasonography and kidding records. Pregnancy was confirmed via transabdominal ultrasound on day 25 post-mating, and goats were re-examined on day 60 of pregnancy to check for fetal viability. The results indicated that estrous synchronization and AI significantly affected pregnancy rates and reproductive quality. This research will assist farmers and researchers in improving management prac-tices in dairy goat reproduction and emphasizes the necessity of employing scientific and modern tech-niques in the livestock industry.
