Table 1 Allocation of birds into various groups for IBV challenge study in the oviduct of laying hens

From: Genes involved in mitochondrial biogenesis and function may not show synchronised responses to mitochondria in shell gland of laying chickens under infectious bronchitis virus challenge

Group Time-point (hr)

IBV T strain (20 birds) 10 birds 10 birds
Control (20 birds) 10 birds 10 birds
  1. Time-point (hr) refers to egg post-oviposition time as determined by video camera. At the time of processing of individual hen, the forming egg was either in the distal magnum/isthmus (5 h time-point) or in the shell gland (15 h time-point)
