Effects of aging on oviposition pattern and egg production traits were studied based on records made between age at first egg and 130 wk of age in 479 hens from three selection lines. During the 1st laying yr (age at first egg to 71 wk of age), all three lines produced equal amounts of egg mass. A significant (P < or = .05) difference in total egg mass production (age at first egg to 130 wk of age) was found between a White Leghorn line selected for egg mass and a Rhode Island Red line selected… CONTINUE READING
