Tenosynovitis in broilers and broiler breeder flocks
New Zealand Veterinary Journal, 1978Abstract Tenosynovitis in commercial broiler breeder flocks, characterised by severe lameness, resulted in malnutrition and eventual culling of these chickens. Histologically there was metaplasia of tendons, tendon sheaths, connective tissues and infiltration with heterophils. Although Staph. aureus was isolated from some specimens, it is probable that

Pose estimation and behavior classification of broiler chickens based on deep neural networks
Computers and Electronics in Agriculture, 2020Poultry behavior is an important indicator for diagnosing poultry diseases. Accurate pose estimation is the basis of poultry behavior analysis, and it provides poultry disease warning methods.

Infectious tenosynovitis in broilers and broiler breeders in Egypt
Veterinary Research Communications, 1984Two infectious tenosynovitis-producing viruses were isolated from tendon sheaths and synovial fluids of 59 broilers and 15 broiler breeders obtained from different flocks in Egypt during June to October 1983. The viruses grew well on the chorioallantoic membrane of developing chicken embryos, produced small localized white pock lesions with oedematous ...

Avian Diseases, 1994
Ten 3-day-old chicks were submitted from a flock experiencing high mortality. Necropsy revealed lacrimation, diarrhea, pleural effusion, hemorrhage and ulceration of the proventriculus, and swollen, hemorrhagic livers. Numerous yellow granules were present in the crop. Assayed crop contents contained 39 ppm diazinon [O,O-diethyl O-(2-isopropyl-4-methyl-

Pasteurella multocida, the etiologic agent of fowl cholera, was isolated from six broiler flocks in Georgia during summer 1988. The flocks ranged in age from 20 to 46 days, represented four companies, and spanned a distance of 50 miles. Increased mortality and lameness were the clinical signs present in all affected flocks. Bacterial isolation and agar

British Poultry Science, 1978
The effect of various factors on the incidence of leg abnormalities, with particular reference to twisted leg, in broilers was studied. The incidence of twisted legs was influenced by strain and for males was twice that for females. There was also a higher incidence in cages than on litter with the type of cage floor having an effect: broilers reared ...

Transmissible proventriculitis in broilers
Avian Pathology, 2007This article reviews transmissible proventriculitis in poultry from 1971 to 2006. The disease is important in commercial broilers worldwide, resulting in reduced profits. The aetiology of this disease is unknown and different clinical presentations often result in a confused or complicated diagnosis.

SUMMARY A total of 3750 broiler chicks were reared on the floor in two experiments replicated 8-12 times. Rate of growth, feed efficiency, mortality, and coccidial lesions were investigated comparing two anticoccidial agents and a negative control group. Lesion scores (severity of 1-4) were determined on sacrificed chicks at 3/2 and 7 weeks of age.
