Beak and feather disease virus (BFDV) is a member of the genus Circovirus and causes psittacine beak and feather disease (PBFD) in Psittaciformes. PBFD is a severe disease generally characterized by immunodeficiency and beak and feather disorders. Although Circovirus spp. have been detected in several nonpsittacine species, little is known about the symptoms and the disease associated with this infection in birds other than Psittaciformes. In this study, we report the identification of Circovirus infection in a flock of Gouldian finches showing beak and feather disorders. Sequence analyses on the rep gene of the virus highlighted a strong similarity at nucleotide and amino acid levels with the corresponding regions of BFDV from psittacine species. By contrast, it was more distant to circoviruses identified in finch and canary.

Light is an important factor affecting the feather pecking behavior in poultry. To evaluate the quality of lighting in production of a local broiler breed, this study was designed to investigate the effects of light color on the growth performance (body weight, feed conversion ratio and upper beak length), welfare parameters (walking step, plumage damage and hormone level) relating to feather pecking and their correlations. One hundred and twenty 49-day-old Youhuang broilers were randomly distributed into 3 lighting treatment groups (warm white, cold white and red) and reared for 4 weeks.

Background: Cellulitis caused by Escherichia coli is a common cause of condemnation of broiler chickens at slaughter worldwide and is associated with economic losses and a possible negative impact on animal welfare. The study objective was to monitor clinical signs and immune responses after subcutaneous E. coli inoculation (1.

In 2021, record snowstorms swept the United States, causing wildlife die-offs that may have been associated with rapid natural selection. Our objective was to determine whether the snowstorms caused natural selection in Eastern Bluebirds ().

Lymphoma was diagnosed in two wild tawny frogmouths (Podargus strigoides) presented to the Australian Wildlife Health Centre, Healesville Sanctuary, Victoria. The first case presented with extensive feather loss refractory to treatment. Bacterial and fungal folliculitis and beak and feather disease virus were excluded as primary causes, and the bird was euthanised due to poor response to treatment.

Article Synopsis
- This study identifies and presents the genomes of two viruses found in cockatiel feces: psittaciform chaphamaparvovirus 5 (PsChPV-5) and beak and feather disease virus (BFDV).
- The genome of PsChPV-5 is 4,366 base pairs long, while BFDV measures 2,009 base pairs.
- Both viruses display the typical genomic features associated with their respective viral groups.
