Effect of egg weight on hatchability and hatchling weight in Fayoumi, Desi and crossbred (Rhode Island Red X Fayoumi) chickens
Aim: An experiment was conducted to determine the effect of egg weight on hatchability, embryonic deaths and hatchling weight of three rural breeds (Fayoumi, Desi and crossbred (Rhode Island Red X Fayoumi) chickens. Materials and Methods: Three different egg weight groups classified into small: (<41g), medium (41-45g) and large (> 45g) were used in the experiment. A complete randomized design w...

متن کاملGenetic Parameters for Production Traits of Rhode Island Red and White Plymouth Rock Breeds Selected under Tropical Condition in Thailand
Egg production data on Rhode Island Red and White Plymouth Rock hens selected for 11 generations under a tropical environment in Thailand were used to estimate genetic parameters for age at first eggs (AFE), body weight at first eggs (BFE), weight of first eggs (WFE), egg production from 1 day to 17 weeks of lay (EGG) and average egg weight at 17 week of lay (EWT). Estimated heritability for AF...
