초록

Least square means for egg weight (EW), average shell thickness (ST), shape index (SI), shell surface area (SA) and shell breaking strength (BS) were determined in the Philippine native (PN) and F2 upgrades with New Hampshire (NH-N) and White Leghorn (WL-N) blood, respectively. Eggs of PN were smaller in size but had higher SI while their egg shells were thinner and weaker than those of the two upgrades. Highest EW, SA and BS means were observed in WL-N. Significant (p<0.01) positive correlations of EW and SI with SA and BS were noted.
