Gs. Brah et al., INHERITANCE OF OVIDUCT WEIGHT AND INTERRELATIONSHIPS WITH OTHER PRODUCTION CHARACTERS IN LAYER CHICKEN, Indian Journal of Animal Sciences, 65(3), 1995, pp. 326-330
Oviduct weight at 72 weeks of age in a selected strain (x = 41.7 g) sh
owed that non-normality of distribution in the form of negative skewne
ss. Sire component heritabilily was 0.65+/-0.32 for oviduct weight, 0.
75+/-0.32 for body weight and 0.86+/-0.33 for egg weight. Oviduct weig
ht had positive genetic correlations, being in the range of 0.52 to 0.
940, with body weight, egg weight, egg number, egg mass and egg produc
tion efficiency. The phenotypic correlations were also positive but lo
wer in magnitude.
