“…The findings of this study provide an important benchmark for the GBADs programme to better understand the benefits that farmed animals offer society, e.g., asset and output value within the TEV concept; compared to the economic burden of animal diseases (e.g., Gilbert et al, 2023 ; Rasmussen et al, 2022 ). The study outcomes offer a baseline for discussions among peak bodies of the livestock and aquaculture sectors, national governments and intergovernmental organisations, e.g., World Organisation of Animal Health, FAO; about potential investment needs in improved animal health, the link between animal health and the future of the global food system as well as the benefits that animals provide society beyond their direct market use value.…”

“…This is because the pooled mortality was estimated in each group of mortality cause separately, without considering a common ceiling. Rasmussen et al proposed a model that makes it possible to aggregate the impacts of a range of endemic diseases in livestock without overlap to prevent potential double counting and overestimation of individual disease impacts (35). Further research will include to use the results of this study in that comorbidity model to account for the productivity and mortality losses attributable to each disease/condition in backyard chickens.…”

Background: Backyard chicken farming is usually subsistence and predominates in low-income countries and, to a lesser extent, in middle-income countries. Chicken flocks are generally raised by households in a low-input, low-output system in contact with other flocks, livestock and wildlife. This low biosecurity setting predisposes chickens to diseases and injuries. A systematic review was conducted to assess the impact of diseases and other causes of mortality in backyard chickens from low and middle-income countries. Results: Out of the 40,121 studies identified, 78 studies were selected. Only a limited number of studies (n=7) assessed productivity impact (weight and egg production losses). Results from the meta-analyses showed that the three main causes of mortality in a production cycle are viral diseases (24.5%, 12.4-42.7), the mix of bacterial and viral diseases (24.2%, 6.2-58.2) and bacterial diseases (11.2%, 4.6-25.0). These three mortality causes also account for the highest proportion of the economic losses for infectious diseases. In the case of non-infectious causes, predation and cachexia are responsible for the highest economic losses in backyard chickens. Conclusions: Infectious diseases account for the highest economic and mortality losses examined in the selected studies. However, losses due to other causes, such as predation should not be overlooked. These results could be used to support animal health policy in informing resource allocation to preventive measures to enhance food security.

“…The Global burden of animal disease (GBADs) is a program, launched in 2018 [21][22][23], aiming measuring and understanding the global burden of animal diseases. GBADs has been working on estimation of biomass and economic value across all livestock species to have common denominators to estimate direct and indirect losses caused by animal diseases worldwide.…”

Background Equids play a crucial role in the Ethiopian economy, transporting agricultural inputs and outputs in the dominant subsistence agricultural systems and the critical link for value chains throughout the country. However, these species are often neglected in policies and interventions, which reflects the data and information gaps, particularly the contribution of working equids to Ethiopia. Objective To assess population dynamics, distribution, biomass, and economic value of equids in Ethiopia. Materials and methods Equine population data were obtained from the Ethiopian Central Statistics Agency (CSA) annual national agriculture surveys published yearbooks from 2004 to 2020. Parameters such as the number of effective service days and daily rental value were obtained from interviews and literature to estimate the stock monetary and service value of equids. Descriptive statistics were used to assess population dynamics and the geographical distribution was mapped. Results The estimated total Ethiopian equid population increased by more than doubled (by 131%) between 2004 and 2020 from 5.7 (4.9–6.6) million to 13.3 (11.6–15) million with 2.1 million horses, 10.7 million donkeys, and 380 thousand mules. Similarly, the number of households owning a working equid has increased. Equine populations are unevenly distributed across Ethiopia, although data were lacking in some districts of the country. The per human-capita equine population ranged from 0–0.52, 0–0.13, and 0–0.02 for donkeys, horses, and mules, respectively. The equid biomass was 7.4 (6.3–8.4) million Tropical livestock unit (TLU) (250 kg liveweight), 10% of total livestock biomass of the country. The stock monetary value of equids was USD 1,229 (651–1,908) million, accounting for 3.1% of total livestock monetary value and the services value of equids was USD 1,198 (825–1,516) million, which is 1.2% of Ethiopian 2021 expected GDP. Conclusion The Ethiopian equine population has grown steadily over the last two decades. Equids play a central role in transportation and subsistence agriculture in Ethiopia and contribute significantly to the national economy. This pivotal role is insufficiently recognized in national livestock investments.
