Abstract excerpt
The effects of presence or absence of individual endogenous virus (ev) genes on production traits was studied in a highly productive commercial layer cross. Age and BW at first egg, egg production, egg weight, and mature BW were recorded for each bird. The birds were examined for presence of ev gene fragments by Southern analysis. A general linear model was used to determine significance of effects of the 21...
