Abstract:
Laparoscopic artificial insemination is an advanced assisted reproductive technique that enables such deep intrauterine deposition of semen and helps bypass the physical barrier of the caudal reproductive tract in small ruminants, leading to higher pregnancy rates. In order to apply laparoscopic artificial insemination to large-scale dairy goat breeding to improve production efficiency, 896 infertile does were selected for laparoscopy for statistics of visualized reproductive disorders; 500 does selected after estrus synchronization for cervical insemination, and 500 selected for uterine horn insemination by laparoscopy were observed for the conception rate. The results showed that only 3.50%(31/896) of infertile dairy goats had normal appearance of ovary and uterus, and the rest had reproductive diseases.The pregnancy rates via laparoscopy yielded higher pregnancy rate(85.20%) with a reduced inseminated volume and a faster postoperative recovery when compared to the cervical insemination(58.00%,P<0.05). The findings suggested that the laparoscopic examination would be helpful to identify the infertile does, and the application of laparoscopic technology in the large-scale breeding of dairy goats can effectively improve the reproduction rate and reduce the breeding cost of pasture.
