Abstract
J emb er R e gency as o n e o f t he r e genci e s wit h t he l a rgest beef c a ttl e p o pul a ti o n in East J a v a, r e c o r ded a high number of FMD cases. In the beef cattle farming business, reproduction is a key factor in the success of beef cattle breeding, therefore this study aims to determine how much impact FMD has on abnormalities in the cattle reproductive system so that it can be known what reproductive disorders occur, the factors that most influence abortion during FMD and the potential economic losses for farmers and business actors engaged in this field in Jember Regency. This study is a quantitative descriptive study aimed at determining the incidence of post-FMD reproductive disorders, identifying the main factors influencing abortion, and estimating the economic losses resulting from abortion and reproductive disorders based on the increase in days open and calving intervals. The results of the study showed that reproductive disorders after FMD were found in 56 % of studied animals with the largest percentage being ovarian hypofunction at 27 %. The incidence of abortion during FMD outbreaks reached 12 % and the most influential factor in the incidence of abortion was FMD virus infection. The economic losses caused by abortions were estimated at IDR 210,840,000 (approximately USD14,000), while the losses due to reproductive disorders calculated on the basis of increased days open and calving intervals were estimated at IDR 1,015,200,000 (approximately USD67,700). Based on the results of this study, it is necessary to further study service per conception, conception rate and calving rate so that the value of the livestock’s reproductive efficiency is known more precisely.
