The pandemic has had far-reaching, devastating effects on human society, the natural world, and the environment on a global scale. The many links in the food production chain, particularly agriculture and cattle, are also badly impacted in terms of product sustainability and monetary losses. There has been a considerable drop in meat, milk, and egg production because of the global epidemic. National and international movement limitations enacted as part of public health sector control efforts have impacted the accessibility of inputs for livestock producers and farm outputs, veterinary services, farmworkers, and animal care businesses. As COVID-19 impacted the global livestock sector which is continuing, understanding and implementing sustainable approaches in livestock production is needed for both academia and industry. To respond to this need, this study carried out a systematic review of the existing literature on the impact of COVID‑19 on the sustainability of livestock performance and welfare on a global scale. Significant consequences on livestock performance sustainability, worldwide animal welfare, and mitigation methods are discussed in this paper in light of the recent outbreak of COVID-19. Keywords: Livestock production; COVID-19; Supply chain; Animal welfare; Sustainability Introduction Worldwide anarchy in 2019 can be traced back to the pandemic Coronavirus epidemic that began that year. The disease has had such a terrible effect on people's health, economies, and social life all across the world that the World Health Organization (WHO) has declared it a pandemic (Zhou et al., 2020). A contributing element to the virus's virulence is the fact that COVID-19 was initially identified in zoo specimens (Tazerji et al., 2020). The virus destroyed all of the towns and ended life as it had been known before in a relatively short length of time. Although lockdown was an essential measure to halt the pandemic's spread, it had devastating unintended consequences for human and animal health and caused a financial disaster on a scale never previously witnessed. The inability of the populace to leave their homes has these results (Shehata et al., 2021). COVID-19 has also had a significant negative impact on agricultural sectors worldwide (Rahman et al., 2021). This has had an obvious effect on the long-term viability of animal production systems, especially those that produce meat and milk, as well as supply chains, trade, and consumers' purchasing patterns (Bekuma, 2020). Global food insecurity is a big issue, especially because of the pandemic's effect on cattle production systems. The situation has worsened as a result of organizational shifts in animal care. As COVID-19 impacted the global livestock sector which is continuing, understanding and implementing sustainable approaches in livestock production is needed for both academia and industry. However, there is a research gap between COVID-19's impact on livestock production and the sustainability of livestock performance. To fill up this research gap, this study carried out a systematic review of the existing literature on the impact of COVID‑19 on the sustainability of livestock performance and welfare on a global scale. The key concerns of this study are the long-term viability of livestock production and the impact that COVID-19 has had on the health and well-being of animals. This review accumulates information from various organizational reports, cited observations, and scientific papers in order to illustrate how the outbreak of COVID- 19 has affected livestock production all over the world, including the dairy, beef, and poultry industries, as well as their respective management systems. This kind of information and data might be helpful in making substantial efforts to improve the current situation and to assert learning for our future, with a particular emphasis on food security through sustainable livestock
