Prolactin Gene and Laying Performance in Aseel Birds

Egg productivity is the most important economic trait in egglaying poultry. Endocrine and environmental factors such as length of photoperiod and feeding allowance can influence egg production [1]. However, a genetic factor would be a prerequisite. Egg production is a polygenic inheritance trait with low to moderate heritability depending on the period involved, a major opportunity for improvem...

Feather pecking behavior in laying hens: hypothalamic gene expression in birds performing and receiving pecks.

Feather pecking (FP) is a welfare and economic problem in the egg production sector. Beak trimming, the current method used to reduce FP, is also criticized. The present study used gene expression to explore the biological mechanisms underlying this behavior, which could lead to a greater understanding of the cause and a tool to mitigate the problem. White Leghorn hens performing and receiving ...

Serological Monitoring of Avian Influenza in Migratory Birds of Iran

  Although migratory waterfowl is well known to be a major reservoir for avian influenza virus (AIV), there are only few recently published reports about the seroprevalence of AIV in this group of birds. To investigate the AIV antibody status in migratory waterfowl of Iran, we collected 217 serum samples from 25 different species of waterfowl during 2003 and 2004. These serum samples were teste...
