Siruvidai and Peruvidai chicken are the major indigenous chicken ecotypes of Tamil Nadu state, India. A study was conducted to assess the fertility and hatchability of Siruvidai chicken hatching eggs incubated in a homestead incubator. The fertility, hatchability and embryonic mortality were recorded.

Avian poxviruses cause pox in different kind of birds. In the present study, investigations of a cutaneous form of pox in pigeons were reported. In June 2017, a Pigeon showing clinical lesions of yellowish crust/nodules on and around beak and eyes and feet was observed in a scattered group of around 40 pigeons. Lesions were collected aseptically in a container with 50% glycerol phosphate buffer solution. After processing of clinical specimen the inoculums were inoculated into chicken embryonated eggs by using chorioallantoic membrane route.

Fowlpox virus (FWPV) and Pigeonpox virus (PGPV) isolates from domesticated fowls and pigeons from Jammu region were inoculated on chorioallantoic membrane (CAM) of chicken embryonated eggs (CEE) through three passage levels to observe their cytopathic effects (CPE) and underlying pathology. Development of PGPV induced lesions was earlier than FWPV, and more severe. PGPV progressed from small white opaque lesions from first passage; to CAM thickening, haemorrhages and very prominent and extensive pock lesions at second; and by third passage, focal areas of necrosis was evident.

F-1 and LaSota strains of NDV were propagated in laboratory using 10-day old embryonated hen eggs via allantoic cavity route. One group of thirty chicks were infected with F-1strain and other with LaSota strain with 105 egg infective doses in 100 µl of virus via oral and ocular route. Sequential sera samples and tracheal samples at day 0, 3,7,14, 21 and 28 post infection were collected and titre of antibodies indicative of humoral immune response was determined by indirect ELISA.

During various Capripox outbreaks in Jammu region, either sheep or goats were found to be affected separately by the disease showing the characteristic cutaneous lesions. Even when both sheep and goats were reared together, the disease was restricted to either host only. Clinical scab samples obtained from both sheep and goats were designated as putative Sheep poxvirus (SPPV) and Goatpoxvirus (GTPV). The isolates were processed and inoculated on the chorioallantoic membrane (CAM) of chicken embryonated eggs (CEE) to study the growth characteristics of the isolates.

The present study was aimed to explore embryonic mortality pattern of fertile eggs of Vanaraja chicken reared on deep litter system. The study was conducted in the year 2016 at Hatchery Unit of West Bengal University of Animal and Fishery Sciences, Mohanpur campus (Nadia District). Birds were divided in 3 age groups as 27 to 40, 41 to 72 and 73 to 92 weeks. Eggs were grouped into three categories; 38 to 41.3, 41.6 to 54.8 and> 55g.

The highly pathogenic H5N1 is a major avian pathogen that crosses species barriers and seriously affects humans as well as some mammals. It mutates in an intensified manner and is considered a potential candidate for the possible next pandemic with all the catastrophic consequences. Methods: Nasal swabs were collected from donkeys suffered from respiratory distress. The virus was isolated from the pooled nasal swabs in specific pathogen free embryonated chicken eggs (SPF-ECE).
