Analysis egg production and egg weight curves by two mathematical models in Japanese quail (Coturnix.C. Japonica)‎

Abstract EN

This study was conducted at the Japanese quail farm of Animal Resource Department/College of Agriculture/University of Basra.

Data of egg production and egg weight were analyzed by using two mathematical models.

A total of 148 birds were used ; 136 females and 12 males.

Family 2 showed highest b parameter values and highest c parameter value compared to other families respecting egg production curves.

R2 values of most families obtained by either Wood or Rational functions were high respecting egg production curve description.

Family 4 showed highest b and R2 values in comparison with other families respecting using Wood function in egg weight curve description.

Family 4 showed highest R2 value compared to other families.
