Poultry Science, 2014 Rearing broilers on flat or sloping wire flooring is an effective method for consistently triggering lameness attributable to bacterial chondronecrosis with osteomyelitis (BCO). Portable obstacles known as speed bumps (SB) also consistently trigger modest incidences of BCO when they are installed between feed and water lines in litter flooring ...

Bacterial chondronecrosis with osteomyelitis ('femoral head necrosis') of broiler chickens: A review
Avian Pathology, 2000Bacterial chondronecrosis with osteomyelitis (BCO) in chickens was first reported in 1972 and is now recognized as an important cause of lameness in broiler chickens. Recent systematic studies of causes of lameness in birds reared in Northern Ireland have shown that it was the most common cause of lameness, being present in 17.3% of lame birds ...

Poultry Science, 2017 Lameness in broiler chickens is a significant animal welfare and financial issue. Bacterial chondronecrosis with osteomyelitis (BCO) leading to lameness can be enhanced by rearing young broilers on wire flooring. Using the wire floor system, we identified Staphylococcus agnetis as the predominant isolate in BCO of the proximal tibiae and femora, and ...

Poultry Science, 2014 Two experiments (E1, E2) were conducted to compare the influence of sires (sire A on dam C vs. sire B on dam C) and straight-run versus sex-separate rearing on the incidence of bacterial chondronecrosis with osteomyelitis (BCO) in broilers. Fertile eggs from commercial breeder flocks were incubated and hatched at the University of Arkansas Poultry ...

CABI Reviews, 2020
Abstract Bacterial chondronecrosis with osteomyelitis (BCO) is one of the leading causes of lameness and welfare concerns in the modern broiler. The avian bone physiology and remodeling process is complex and dependent on numerous bone and vascular cell types and pathways working harmoniously. The rapid growth rate of the leg bones in

New genes involved in the Bacterial Chondronecrosis with Osteomyelitis in commercial broilers
Livestock Science, 2018Abstract Locomotor problems have a great economic impact on world poultry production, because difficulty of locomotion leads to a decrease in animal performance and an increase in partial or total carcass condemnation. In addition, locomotor problems greatly affect the chicken welfare.

Leg disorders in poultry: bacterial chondronecrosis with osteomyelitis (BCO)
2017Bacterial chondronecrosis with osteomyelitis (BCO) is widely recognized as one of the most common causes of lameness in broilers. This chapter starts by summarizing the pathogenesis of BCO. Experimental models that successfully trigger BCO are then reviewed. Sources of bacteria that infect the bones are discussed, with the primary emphasis on bacterial

Osteomyelitis remains a serious inflammatory bone disease that affects millions of individuals worldwide and for which there is no effective treatment. Despite scientific evidence that Staphylococcus bacteria are the most common causative species for human bacterial chondronecrosis with osteomyelitis (BCO), much remains to be understood about the ...

Bacterial chondronecrosis with osteomyelitis (BCO) lameness is the most prevalent skeletal disorder in poultry, implicated by the inherent risk of the high growth rate of modern broilers. The non-synchronization of massive body mass accretion vs maturation of the structural bone induces vulnerability to bone microfracture and immunosuppression, leading
