  1. Multiple comparisons were performed to calculate differences in the least square means (LSM) by the Duncan’s Multiple Range test. The numbers of DD (homozygous deletion type), ID (heterozygous type) and II (homozygous insertion type) birds were at least 270, 90 and 55. The data were presented as (LSM) ± Standard error (SE).
