While specific studies on nutritional interventions were not highlighted in the provided data, it is well-established that good nutrition supports overall animal health and resilience against infections. Figure 1 Classification of herds in the Norwegian control program for bovine respiratory syncytial virus (BRSV) and bovine coronavirus (BCoV). Samples of milk and serum are analyzed for antibodies against BRSV and BCoV using a BCoV/BRSV multiplex immunoassay (Adopted from Stokstad et al., 2020) 3.4 Environmental management Environmental management involves maintaining clean and hygienic living conditions for animals to reduce the risk of disease. This includes regular cleaning and disinfection of animal housing, proper waste disposal, and ensuring adequate ventilation. The Norwegian BRSV/BCoV control program also emphasizes the importance of improving the animal's environment as part of a comprehensive disease prevention strategy (Stokstad et al., 2020). Additionally, a study on biosecurity practices in Belgian cattle farms found that better environmental management practices, such as reducing animal-to-animal contact and controlling professional visits, could significantly lower the risk of disease transmission (Sarrazin et al., 2014). Effective environmental management is thus a crucial component of disease prevention and control in livestock farming. 4 Disease Control Methods 4.1 Early detection and diagnosis Early detection and diagnosis are critical components in the control of animal diseases. Effective surveillance systems are essential for the timely identification of disease outbreaks, which allows for prompt intervention and minimizes the spread of infections. Diagnostic tests play a crucial role in this process, enabling the early detection of infected animals and facilitating the implementation of control measures. For instance, the availability of adequate diagnostic tests is vital for the early detection of notifiable diseases, which can significantly impact livestock health and human health (Álvarez et al., 2019). Surveillance systems systematically collect, collate, and analyze data on disease occurrence, helping to detect changes in disease trends and distribution (Fenner et al., 1987). In animal shelters, diagnostic tools are used to identify infectious diseases such as heartworm, with protocols in place for testing and managing infected animals (Colby et al., 2011; DiGangi, 2020). 4.2 Quarantine and isolation practices Quarantine and isolation practices are fundamental in preventing the spread of infectious diseases among animal populations. These measures involve separating healthy animals from those that are suspected or confirmed to be infected. Quarantine is particularly important during the introduction of new animals into a herd or shelter, as it helps to prevent the introduction of new pathogens. Effective quarantine and isolation protocols are essential for controlling diseases such as canine parvovirus and feline upper respiratory disease in animal shelters (Steneroden et al., 2011). Movement control and quarantine are also key strategies in the broader context of disease eradication
