“…These findings highlight the multifactorial nature of goat abortion, with infectious agents, environmental factors, and management practices all playing a role. Abortion in small ruminants not only leads to reproductive losses [12,13] but also poses zoonotic risks, as some causative agents can transmit to humans [14][15][16][17].…”

Background Small ruminants are the principal component of livestock production in Tigray region, Ethiopia. But their productivity is affected by various factors. According to farmers and expert observation, goat abortion is among the leading causes of production losses in Tanqua-Abergelle district. However, study findings that examine the extent of distribution and economic impact of abortion cases in goats in the district are scarce. This retrospective study investigated the occurrence of abortion and its associated risk factors in three goat breed types at Abergelle Agricultural Research Center goat breeding site over a seven year period. The study included a total of does above one year old, and data were collected from a casebook that was specifically prepared for abortion cases. A thorough follow up was conducted to identify abortion cases. Additionally, a community survey was conducted in selected villages where the research center is located. Results The overall abortion proportion was 29.8% in the goat farm. Begait goat breeds had the highest abortion proportion (50.9%, CI 0.36–0.64) in 2015/16. Multivariate logistic regression analysis identified year, season, age and breed as major risk factors of abortion occurrence at flock level. Accordingly, the likelihood of goats experiencing abortion during the dry season (proportion = 34) was 1.87 times higher compared to those in the wet season (proportion = 22.8). Begait breeds had a higher incidence of abortion (proportion 37.5%, OR 4.87, CI 2.49–10.35) compared to other breeds. Age was negatively associated with abortion, suggesting that older goats (OR = 0.67) had a higher relative risk than younger goats (OR = 0.57). Moreover, the study noted a high incidence of abortion during the years 2014/15 to 2016/17 (proportion = 35.7–39.7). Within-breed analysis revealed that age and season were significant risk factors for Abergelle and Begait breeds, respectively by using a multivariate logistic regression analysis. A community survey indicated that 89.7% households responded their goats experienced abortion. Conclusions This study highlighted the high prevalence of goat abortion at Abergelle and identifies important risk factors associated with its occurrence. The findings can inform targeted interventions to reduce abortion rates and improve goat productivity in the district.

“…Among them, various infectious agents can cause serious disease in human beings. As a consequence, abortion results reproductive loss in small ruminants [10,11] and the infectious causative agents can also have severe zoonotic implications [12,13,14,15]. Goat rearing is the rst and the most important economic activity in Tanqua Abergelle district with an estimated 154,330 goat population in the district [16, 1].…”

Background Abortion is among the leading cause of production losses in Tigray. A retrospective study on abortion cases were conducted for over seven years in goat farm located in Tanqua Abergelle district of Ethiopia with the objectives of investigating the occurrence of abortion and associated risk factors. Results The study illustrated that the overall abortion rate observed was 29.8% in the goat farm. The highest abortion rate was observed in Begait goat breeds (50.9%, CI 0.36–0.64) during the 2015/16 study year. The chi-square test and univariable regression analysis revealed that the overall abortion rate significantly varied with breed type, season, age, and year (P < 0.05) but no variation with parity (P > 0.05). Accordingly, goats during the dry season (OR 1.74, CI 1.28–2.37) were more likely to have abortion than during the wet season (OR 0.29, CI 0.23–0.37) and Begait breeds (rate. 37.5%, OR 3.5, CI 1.85–7.23) show higher abortion as compared to the other breeds. Looking at the within breeds (animal level), the factors parity, age, years and season (p < 0.05) were among the important factors in Abergelle breeds, season and study years (P < 0.05) were significantly differed in Begait breeds, and none of the factors were important in cross breeds for the occurrence of abortion. A survey at the community level (outside the farm) revealed that 26 out of 29 (89.7%) households responded that their goats experienced abortion. Conclusions The results showed that high abortion rate and seasonally and/or yearly varied abortion cases were observed along with causative agents remained to be investigated. This research finding could provide essential information for the breeding research center and nearby farmers to introduce better management, and abortion prevention methods. In addition, appropriate investigation to identify the causes of abortion should be the next research direction.
