“…The results of our study show that the development of resilient, disease-tolerant animals improves the economic performance and the economic sustainability of the farm. This finding is in line with those of Nieuwhof and Bishop [65], Knight-Jones and Rushton [66], Winter and Green [37], Nathues et al [67], Limon et al [68], and Tadesse et al [69], who concluded that the reduction of incidences of infectious and noninfectious diseases has direct economic benefit for the farms and the industry. These studies follow a similar approach to ours, considering the associated costs of prevention and treatment but also the reduced animal performance and the corresponding production losses.…”

In this study, a farm-scale mathematical programming model for sheep and goat farms is proposed to simulate economic performance, including new resilience sheep traits that allow animals to counteract the presence of infectious and noninfectious diseases. The model was developed in the Small Ruminants Breeding for Efficiency and Resilience (SMARTER) Horizon 2020 project. The SMARTER model is a comprehensive and adaptable linear programming model that enables the assessment of hypothetical scenarios/challenges related to animal traits that prevent infectious and noninfectious diseases. The optimal performance and the structure of the farm are modeled under the presence of infectious and noninfectious diseases (disease plan) and under conditions where no diseases occur (future plan). A comparison of the model solutions, between presence and absence of diseases, provides suggested adjustments to the farming system and insights into the potential shape of new sustainable farm system profiles for the sheep and goat sector. Technical and economic data from five different sheep farms and one goat farm in Greece and France were used in this empirical application to assess different scenarios in the presence of mastitis, parasitism, and lameness in the flocks. The results showed that the profitability and sustainability of the farms are significantly improved when the resilience of animals reduces the impact of the diseases (the highest increase in gross margin was 23.5%). However, although there is substantial improvement in the economic performance of the farms that rear healthy animals, this does not affect the production and management plan of the farmer and does not alter the farm’s structure.

“…This describes that a sheep and goats virus will continue its propagation among susceptible members of the sheep and goats, if no environmental changes or external influences intervene. This finding is higher as compared to the report of Tadesse et al [ 38 ] in Chifra districts of Afar region, who reported a R0 of 1.41. The values of R0 indicate that a single SP and GP virus infected animal can transmit for 1.84 sheep and goats for Haroye kebele and three sheep and goats for Kundi kebele's respectively.…”

“…Due to the significant implications of these new outbreaks, additional investigations into the reasons for northward incursions into the central regions are required. SPP outbreaks were more prevalent during summer months than during winter months, possibly due to the contagious nature of SPPV and the mode of virus transmission [30,31]. When sheep are confined to stall keeping during the winter in Russian Central and Northern regions, important mechanisms of SPPV infection transmission are mitigated by subsequent isolation and movement control.…”

Sheeppox (SPP) is a transboundary infectious disease that affects sheep and goats, leading to significant losses in countries with extensive small ruminant breeding programs. While sporadic SPP outbreaks have been observed in the Russian Northern Caucasus and the Far East, the number of SPP outbreaks in the Russian Central and Far East regions has increased recently. However, there is a lack of epidemiological data on SPP virus (SPPV) in the Northern latitudes. In this study, we conducted epidemiological and genetic analyses of SPP outbreaks in Russia from 2013 to 2021 using whole-genome sequences of five selected isolates. The epidemiological data revealed an elevated risk of SPP outbreaks during the summer months, although outbreaks were not limited to this period. A phylogenetic analysis of the whole-genome sequences of selected SPPVs obtained directly from clinical samples revealed a unique cluster of SPPV isolates circulating in Central Russia, which was related to previous isolates from the European part of Russia. In contrast, SPPVs obtained from the Russian Far East showed genetic similarity to isolates detected in Southeast Asia. The whole-genome sequences demonstrated that the reported outbreaks were not related to the NISKHI vaccine strain, which was used to combat lumpy skin disease and SPP in Russia. Based on the study findings and GenBank data, we propose a novel cluster designation system for SPPV genomic sequences.
