The genetic parameters associated with egg production and related traits in a sex-linked dwarf strain of single comb White Leghorns (Gallus domesticus)

Creator:

Ngam, Joe Eric Tosah

Abstract:

The records of a population of sex-linked dwarf layers at the Oregon State Agricultural Experiment Station subjected to an accelerated selection for hen-housed egg production at 40 weeks of age for a period of over 11 years were analyzed for selection response, and for the estimation of genetic parameters. The...

Accelerated selection for hen-housed egg production and correlated responses in White Leghorns (Gallus domesticus)

Creator:

Cáceres, Oscar

Abstract:

The records of a population of White Leghorns at the Oregon State Agricultural Experiment Station, submitted to accelerated selection for hen-housed egg production on an individual and a family basis at 40 weeks of age for 18 years, were studied. An analysis was made to determine the relative efficiency of...
