6 wrz 2022 · Bovine respiratory disease (BRD) is a general term for a range of respiratory disorders that can affect the lower respiratory tract in cattle. BRD is the second most common disease impacting the global beef industry, after neonatal calf diarrhoea [1], being a particular burden in young cattle and pre-weaned calves.
Conditions that negatively affect dry matter intake and nutrient absorption, such as heat stress, subacute respiratory acidosis (SARA), and the inadvertent inclusion of mycotoxins in the diet may result in altered immune function and increased susceptibility to respiratory disease.79, 80, 81, 82 SARA can also have a direct effect on respiratory ...
12 sty 2022 · The bovine respiratory microbiome is strongly associated with health and disease and may provide insights for alternative therapy when treating BRD. The niche-specific microbiome communities that colonize the inter-surface of the upper and the lower respiratory tract consist of a dynamic and complex ecological system.
16 lut 2024 · Bovine Respiratory Disease (BRD) poses a significant challenge in managing cattle health. This intricate disease affects both the upper and lower respiratory tracts in cattle and is influenced by various environmental, host, and microbial factors.
1 sie 2008 · Bovine respiratory disease complex (BRDC) is the most common and costly disease of cattle. The important prevalence of this multifactorial syndrome results from interactions between different...
This review aims (1) to summarise briefly the anatomical, histological and physiological peculiarities of the bovine respiratory system and (2) to consider the effect of breed, heritability and external factors at each step of the oxygen transport chain, by focussing essentially on respiratory function.
Among lower respiratory tract disorders, infectious BRD is due to airborne pulmonary infection by viruses and bacteria, including mycoplasma, but also to the hematogenous spread of infection (thromboembolic pneumonia) and to parasites (verminous pneumonia), while non-infectious BRD includes atypical interstitial pneumonia (acute pulmonary ...
