“…Thus, there is the potential to use these behaviors for algorithm development to detect recovery status in calves in future research. We suggest that minimizing the duration of BRD status in calves is essential to promote calf well-being 10 .…”

“…Other sickness behaviors in calves, such as self-isolation behavior 6 , depressive behaviors with signs of physical pain 7 , labored breathing 8 , and lateral lying 9 can be directly observed (e.g., by video recordings). Thus, it is likely that BRD bouts compromise a calf’s welfare and the time a calf experiences disease should be minimized 10 . Bovine Respiratory Disease Complex (BRD) also presents a sustainability issue since calves often require multiple antimicrobial interventions to treat the disease.…”

Calves with Bovine Respiratory Disease (BRD) have different feeding behavior and activity levels prior to BRD diagnosis when compared to healthy calves, but it is unknown if calves who relapse from their initial BRD diagnosis are behaviorally different from calves who recover. Using precision technologies, we aimed to identify associations of feeding behavior and activity with recovery status in dairy calves (recovered or relapsed) over the 10 days after first antimicrobial treatment for BRD. Dairy calves were health scored daily for a BRD bout (using a standard respiratory scoring system and lung ultrasonography) and received antimicrobial therapy (enrofloxacin) on day 0 of initial BRD diagnosis; 10–14 days later, recovery status was scored as either recovered or relapsed (n = 19 each). Feeding behaviors and activity were monitored using automated feeders and pedometers. Over the 10 days post-treatment, recovered calves showed improvements in starter intake and were generally more active, while relapsed calves showed sickness behaviors, including depressed feed intake, and longer lying times. These results suggest there is a new potential for precision technology devices on farms in evaluating recovery status of dairy calves that are recently treated for BRD; there is opportunity to automatically identify relapsing calves before re-emergence of clinical disease.

“…The parasite-stress theory of values is based on existing knowledge of parasitic ecology and evolution (i.e., infectious disease). Infectious illnesses were a major source of morbidity and mortality throughout human evolution (Bull et al, 2021). By this idea, values are adaptive responses to illness risks.…”

Travel risk and management views of tourists have a key role in their choice of locations while the COVID-19 epidemic is still causing travel-related concerns. Despite many studies available in the western world, the effect of COVID-19 has been less explored in Nepal. Thus, this research aims to investigate travel risk and management perception in post-COVID tourism activities in Nepal. Based on pathogen stress theory and explanatory research design, this study seeks a causal relationship between Travel Risk and Management in Nepal. Following the purposive sampling technique, data collection is done using KOBO Toolbox through a structured questionnaire. Findings revealed that Risk Management, Transportation Patterns, Distribution Channel, Avoidance of Overpopulated destinations, Hygiene and Safety are significant to Travel risk and management perception whereas Risk Management, Travel risk and management perception, Service Delivery, Distribution Channel, Hygiene and Safety are significant to COVID-19 pandemic in Nepal which supports pathogen-stress theory. Furthermore, travel risk and management perception partially mediate the favorable association between avoidance of overpopulated destinations and the COVID-19 pandemic. Additionally, the primary problems faced by the traveler were securing a comfortable hotel and selecting a destination where COVID risk is minimum. However, the COVID-19 break has caused health concerns among visitors, causing many to cancel their holiday plans. Therefore, in the post-pandemic phase, tourists are more concerned about the influence of the COVID-19 pandemic on their travel activities and choice.

“…Since the 1960s, bovine respiratory disease (BRD) has been a major challenge for the beef and dairy industry, particularly in veal calf farming, as well as for veterinarians and researchers. Clinical BRD may require the application of antimicrobial drugs, increased labor, and decreased welfare [1][2][3]. Additionally, reduced profitability due to decreased performance and death is frequent [4].…”

The prevention of bovine respiratory disease is important, as it may lead to impaired welfare, economic losses, and considerable antimicrobial use, which can be associated with antimicrobial resistance. The aim of this study was to describe the prevalence of respiratory viruses and to identify risk factors for their occurrence. A convenience sample of 764 deep nasopharyngeal swab samples from veal calves was screened by PCR for bovine respiratory syncytial virus (BRSV), bovine parainfluenza-3 virus (BPI3V), bovine coronavirus (BCoV), influenza D virus (IDV), and influenza C virus (ICV). The following prevalence rates were observed: BRSV, 2.1%; BPI3V, 3.3%; BCoV, 53.5%; IDV, 4.1%; ICV, 0%. Logistic mixed regression models were built for BCoV to explore associations with calf management and housing. Positive swab samples were more frequent in younger calves than older calves (>100 days; p < 0.001). The probability of detecting BCoV increased with increasing group size in young calves. Findings from this study suggested that young calves should be fattened in small groups to limit the risk of occurrence of BCoV, although an extended spectrum of risk factors for viral associated respiratory disorders such as nutritional aspects should be considered in future studies.
