In small ruminants, abortions may occur due to infectious and non-infectious causes. Infectious abortions are caused by bacteriological, virological, protozoal, or fungal factors. Infectious factors cause many different negative effects at the herd health level but also cause significant decreases in fertility characteristics. The present study aimed at evaluating the fertility, birth, and newborn findings of a goat flock that was synchronized with intravaginal sponge application and was found to be infected with Border Disease Virus (BDV). Medroxyprogesterone acetate-impregnated intravaginal sponge (Esponjavet, Hipra, Spain) and 500 IU PMSG (Oviser, Hipra, Spain) were applied to 192 goats in a Saanen goat flock farm with 340 broodstock to control the reproductive activities during nonbreeding season. After removal of the sponge, 150 goats (78%) had estrus response and mated with fertile bucks. A total of 115 goats (60%) became pregnant. Pregnancy diagnosis was performed by transrectal ultrasonography within 30-45 days after mating. Regarding re-control of pregnancies on the 90th day, 80 goats (42%) were determined to be pregnant. Some congenital deformities (brachygnathism, joint bletures, hair disorders, small and weak kids), abortions (8), stillbirths (8), and embryonic deaths (34) were also detected in the herd. BDV antibody and antigen tests were positive in serological tests of kids with clinical findings. This result was compatible with the findings of kids and pregnant goats. This study clearly demonstrated that it is beneficial to search for factors in terms of BDV in enterprises with fertility problems. Effective herd health programs are essential in rearing management and disease control in livestock. In dairy goat farms, these programs are intended to monitor, treat and prevent health problems as well as ensure animal welfare and they are prerequisites for providing sustainable and profitable dairy goat farms.
