Captive rearing of insect pests is necessary to understand their biology and to develop control methods. The avian nest fly, Philornis downsi Dodge and Aitken, is a blood-sucking parasite during its larval stage and a serious threat to endemic birds in the Galapagos Islands where it is considered invasive. In order to procure large numbers of flies for biological studies, rearing media and diet...

The growth kinetics of avian infectious bronchitis (AIB) virus in vitro have been investigated previously using different systems, including embryonated chicken eggs (Hitchner and White, 1955), and cell cultures of chick embryo kidney (Lukert, 1965 ; Bulow, 1966; Akers and Cunningham, 1968) or chick embryo liver (Lukert, 1965). Organ cultures of ciliated epithelium have been employed in various...

Objective(s): In veterinary medicine, zeolites are used as toxin binder in animal feed, ammonia purification of aquatic pools, animal smell and moisture control. This study investigated on the risk assessment of nano zeolite on development of embryonic chicken models, anomalies, tetratogenic and embryotoxic effects. Methods: Eggs (120 = n) were accidentally di...

AIM The objective of the present study was to examine pock forming ability of field strain and vaccine strain of fowl pox virus (FPV) in chorioallantoic membrane (CAM) of embryonated chicken eggs and its adaptation in chicken embryo fibroblast (CEF) cell culture. MATERIALS AND METHODS Dry scabs were collected from 25 affected birds in glycerin-saline and preserved at 4°C until processed. Viru...

A commercial egg-type chicken (ISA Brown; CEC) and a dual-purpose pure breed of the Korean Native Chicken (KNC) were compared for yolk to albumen (Y:A) ratio and their major egg characteristics at seven different ages. The eggs from KNC were significantly (P < 0.01) lighter in egg, albumen, and shell weight than those from CEC. However, the yolk weight and Y:A ratio of the eggs from KNC were si...
