Abstract

In order to assess genetic attributes on immune traits of three varieties of domesticated Japanese quails developed by CARI (CARI-UJJAWAL, CARI-SUNEHERI AND CARI-BROWN) were chosen at random from the base populations and reared in individual cages to maintain sire and dam pedigree record system. Records of 160 progenies from 180 sires and 180 dams of each variety analysis carried using restricted maximum likelihood (REML) animal model. The progenies (480 birds) were exploited to predict the genetic variations in immune traits at 5th (Humoral) & 7th (cell mediated immunity) week of age. Analysis of data revealed that HA titre values was significantly (p<0.01) differed among the varieties and also the hatches. Sex had a no significant impact on the immune traits. For foot pad index test, varieties had significant (P<0.01) effect. But there was no significant effect between sex and also between hatches. Heritability estimates of the immunological traits based on the sire component of variance for antibody titre (HA) ranged from medium to high (0.25 to 0.44), and estimates were low in Foot pad index (0.011 to 0.171) in all the varieties.
