An outbreak of avian pox was detected among captive peacocks (Pavo cristatus) at Baghdad Zoological Park during spring, 1978. A total of 45 of the 60 birds in the aviary developed pox lesions around the beaks and eyes. Morbidity was 75% and mortality was 13%. A virus isolated from the skin lesions produced large plaques on the chorioallantoic membrane of developing chicken embryos and induced cytopathic effect characteristic for pox viruses in chicken embryo cell cultures. The virus neither haemagglutinated nor haemadsorbed to chicken erythrocytes. It was ether resistant and chloroform sensitive. Chickens inoculated with the virus by scarification developed localized pox-like lesions, while turkeys had only transient swelling of feather follicles at the site of inoculation. Virus partially purified with Genetron 113 was precipitated by antisera to fowlpox and pigeon pox viruses.

The gastrointestinal tract (GIT) of animals contains various helminth parasites, responsible for subclinical and clinical parasitism. The health situation of animals is seriously affected by these parasites and leads massive financial losses for the livestock trade. The present study was conducted to determine the prevalence and associated risk factors of GIT parasites in small and large ruminants of Mardan district and zoo animals of Golden Life Safari Park Khyber Pakhtunkhwa.

Newcastle disease has been endemic within the Iranian poultry industry for decades. However, the genetic nature of the circulating Hemagglutinin-Neuraminidase (HN) gene among Iranian domesticated bird populations is broadly unexplored. The presented study was carried out to gain insights into the biological and molecular characterization of four complete HN genes isolated from turkey, peacock, and broiler isolates in Iran between 2018 and 2020.

We describe unique reproductive features of two threatened Galliformes species, the Malaysian peacock-pheasant (Polyplectron malacense) and Bornean peacock-pheasant (P. schleiermacheri). These features pose challenges to successful captive breeding to build up sustainable populations for conservation purposes.

Article Synopsis
- Ectoparasitism in ornamental birds, particularly peacocks, poses significant health risks, with up to 13 lice species causing issues like anemia; thus, new treatments like isoxazolines are being explored.
- A study evaluated the effectiveness of afoxolaner on peacocks infested with Goniodes pavonis, comparing treated and untreated groups.
- Results showed that afoxolaner significantly reduced lice presence and improved the blood health of treated peacocks without adverse effects, indicating its potential as a safe and effective treatment.

Background: Newcastle disease (ND) is one of the most deadly diseases of poultry around the globe. The disease is endemic in Pakistan and recurrent outbreaks are being reported regularly in wild captive, rural and commercial poultry flocks. Though, efforts have been made to characterize the causative agent in some of parts of the country, the genetic nature of strains circulating throughout Pakistan is currently lacking.
