The economic impact and control measures of bovine respiratory disease : a qualitative approach
| Resumo: | Bovine Respiratory Syncytial Virus (BRSV) is a well-known cattle virus, and a key intervenient in the genesis of Bovine Respiratory Disease (BRD). Given its importance, the development of a DIVA vaccine has been established as one of the objectives of a European research project named SAPHIR. BRD is one of the most widespread and costly cattle diseases worldwide but, despite the recognition of its relevance and the substantial investments made in control expenditures, there is still a considerable lack of knowledge concerning its actual economic impact in the dairy and meat cattle value chain. With the objective of collecting primary data concerning epidemiology, presence of risk factors, production losses and expenditures in BRD prevention and treatment on Portuguese farms, two questionnaires were developed and implemented using a convenience sample of five dairy and five meat farms. This case study led to the conclusion that, despite being present in the majority of the farms surveyed, there seems to be an over-all lack of data concerning the quantification of BRD’s economic impacts in primary production, regardless of their recognition and considerable expenditures on medical and prophylactical tools. As proposed, the case study allowed for the identification of gaps concerning BRD and its management, with future work needing to be focused on obtaining a deeper knowledge regarding the meat cattle value chain, evaluating the existence of detailed treatment and vaccination records at farm level, as well as accurate disease prevalence and incidence, and quantification of existing production losses. Considerable control expenditures were also seen in a case study conducted by researchers from the Royal Veterinary College under the SAPHIR project. Despite their presence at farm level, it seems rather difficult to establish a direct correlation between risk factors and disease presence and magnitude. This finding reflects the complex multifactorial nature of BRD, and was transversal to both studies. |
