“…Nevertheless, this is the first estimated projection of the nationwide effects of BRD on confined cattle reared in Brazil, and provides an insight of the approximate economic impacts of BRD on the local beef industry, using the indices determined during this investigation as baseline input data. Although the annual estimated cost identified during this study is below the $750 million that is associated with BRD in the USA [25], the amount of cattle on feed in the USA is comparatively more elevated than in Brazil, so the value herein described should not be underestimated. However, the projected total economic loss ($11.85 million) due to BRD will affect the local beef cattle producing industry, considering that this amount represented only 1.83% of all cattle reared in Brazil.…”

“…The information herein obtained is of fundamental importance to guide and alert local beef cattle producers on the importance of curbing expenses associated with BRD, since there was no available data that considered the peculiarities associated with feedlot cattle production in Brazil. Consequently, the data contained in this study can be compared with those of similar investigations done in North America [24][25][26][27][28], where the impacts due to BRDrelated disease are well established [6].…”

Introduction: A feedlot is an intensive farming system for finishing livestock. Bovine respiratory disease (BRD) is a cause of morbidity and mortality in beef cattle, especially in feedlots. Methodology: This study investigated the morbidity and mortality of BRD in a beef cattle feedlot in southeastern Brazil using: clinical diagnoses, therapy, morbidity, and mortality. Pulmonary fragments were collected from five steers, on feed from 3-32 days, with lesions of pneumonia for identification of BRD infectious agents PCR. Results: 188,862 steers were on feed and morbidity was 7.05% (13,315/188,862), mortality 0.64% (1,214/188,862). The causes of morbidity were: BRD (6.13%), lameness (0.29%), trauma (0.21%), clostridiosis (0.13%) and polioencephalomalacia, PEM (0.12%). The causes of mortality were: BRD (0.21%), trauma (0.17%), and clostridiosis (0.13%). When all sick cattle were considered (n=13,315), BRD (86.9%) was the principal cause of morbidity, followed by lameness (4.13%), trauma (3.05%), and clostridiosis (1.82%). The cost of BRD-associated cattle mortality and morbidity was estimated at $14,334.00/10,000 and $16,315.40/10,000 respectively. It was projected that the economic effects due to BRD-associated morbidity in Brazil were $6.31 million/annum, while losses due to mortality were $5.54 million, resulting in an annual loss of $11.85 million. Coinfections in cattle with pneumonia due to Mannheimia haemolytica and Pasteurella multocida were identified in 4/5 steers tested. Conclusions: This is the first longitudinal study that investigated the incidence of BRD in feedlot cattle from Brazil, and the results herein described indicate that BRD contributed significantly to the development of mortality and morbidity of cattle on feed.

“…These costs are unequivocally brought by respiratory diseases [65,119,157] since about 25% of the calves experience at least one episode of respiratory disease during the first year of life, with frequencies over six birth years ranging from 14 to 38%. The incidence of bovine respiratory diseases is greater in male calves than in female calves during both preweaning and feedlot periods [133].…”

How Mannheimia haemolytica defeats host defence through a kiss of death mechanism

-Mannheimia haemolytica induced pneumonias are only observed in goats, sheep and cattle. The bacterium produces several virulence factors,whose principal ones are lipopolysaccharide and leukotoxin. The latter is cytotoxic only for ruminant leukocytes, a phenomenon that is correlated with its ability to bind and interact with the ruminant β2-integrin Lymphocyte Function-associated Antigen 1. This paper globally reviews all the information available on host-pathogen interactions underlying respiratory mannheimiosis (formerly pasteurellosis), from the stable and the Petri dish to the biochemical cascade of events triggered by the leukotoxin inside ruminant leukocytes. One conclusion can be made: the most widespread cattle respiratory disease with the most important impact on beef production worldwide, is probably due to a tiny ruminant-specific focal variation in the CD18-and/or CD11a-expressing genes.

“…The overall cost to the industry has been estimated as $750 million per year (Griffin, 1997). A single treatment for BRD has been estimated to cost $15.57 (Faber et al, 1999) due to expenses related to pharmaceutical products and supplies, whereas total associated costs of BRD treatment as it relates to loss of production and decreased carcass value have been reported at $92.26 (McNeill et al, 1996).…”

The primary objective of this study was to estimate variance components and heritability of bovine respiratory disease (BRD) incidence in beef calves before weaning and during the finishing phase. The second objective was to investigate the impact of BRD incidence and treatment frequency on performance and carcass traits. Bovine respiratory disease is the biggest and most costly health challenge facing the cattle industry. The 2 populations used consisted of 1,519 preweaned calves and 3,277 head of feedlot cattle. The incidence rate of BRD in preweaned calves was 11.39%, and among treated cattle, 82.1% were treated once, 13.9% were treated twice, and 4.0% were treated 3 times or more. The incidence of BRD (P = 0.35) and the number of treatments (P = 0.77) had no significant effect on weaning BW. Heritability estimates of the entire preweaned population for BRD resistance and number of treatments were 0.11 ± 0.06 and 0.08 ± 0.05, respectively. The genetic correlation estimates for BRD incidence with weaning BW and birth BW were low (−0.02 ± 0.32 and 0.07 ± 0.27, respectively). The same estimate for the number of BRD treatments with weaning BW and birth BW was 0.25 ± 0.35 and 0.30 ± 0.27, respectively. The observed BRD incidence rate for feedlot cattle was observed at 9.43%. Incidence of BRD significantly (P < 0.01) decreased overall and acclimation ADG by 0.06 ± 0.01 kg/d and 0.28 ± 0.03 kg/d, respectively. Carcass traits were also significantly (P < 0.05) affected by BRD incidence; untreated cattle had a 9.1 ± 1.7-kg heavier HCW. Results were similar in the analysis of treatment frequency. The heritability estimate of BRD incidence and the number of treatments were 0.07 ± 0.04 and 0.02 ± 0.03, respectively. Estimates of genetic correlations of BRD incidence with production traits were −0.63 ± 0.22 for acclimation ADG, −0.04 ± 0.23 for on-test ADG, −0.31 ± 0.21 for overall ADG, −0.39 ± 0.21 for final BW, −0.22 ± 0.22 for HCW, −0.03 ± 0.22 for LM area, 0.24 ± 0.25 for fat, and −0.43 ± 0.20 for marbling score. Similar results for the number of treatments and production traits were −1.00 ± 0.68 for acclimation ADG, −0.04 ± 0.39 for on-test ADG, −0.47 ± 0.41 for overall ADG, −0.66 ± 0.40 for final BW, −0.58 ± 0.45 for HCW, −0.12 ± 0.38 for LM area, 0.42 ± 0.50 for fat, and −0.32 ± 0.37 for marbling score. Because of the high economic cost associated with BRD incidence, even these modest estimates for heritability of BRD resistance should be considered for incorporation into beef cattle breeding programs. ABSTRACT:The primary objective of this study was to estimate variance components and heritability of bovine respiratory disease (BRD) incidence in beef calves before weaning and during the finishing phase. The second objective was to investigate the impact of BRD incidence and treatment frequency on performance and carcass traits.
