AB  - 1. The aim of the following experiment was to estimate transgenerational 
      epigenetic variance for egg quality traits using genealogical and phenotypic 
      information in meat-type quail. Measured traits included egg length (EL) and 
      width (EWD), albumen weight (AW), shell weight (SW), yolk weight (YW) and egg 
      weight (EW). 2. A total of 391 birds were evaluated for egg quality by collecting 
      a sample of one egg per bird, during three consecutive days, starting on the 14th 
      d of production. Analyses were performed using mixed models including the random 
      epigenetic effect. Variance components were estimated by the restricted maximum 
      likelihood method. A grid-search for values for the auto-recursive parameter (lambda) 
      was used in the variance components estimation. This parameter is directly 
      related to the reset (v) and epigenetic transmissibility (1 - v) coefficients. 3. 
      The epigenetic effect was not significant for any of the egg quality traits 
      evaluated. Direct heritability estimates for egg quality traits ranged in 
      magnitude from 0.06 to 0.33, whereby the higher estimates were found for AW and 
      SW. Epigenetic heritability estimates were low and close to zero (ranging from 
      0.00 to 0.07) for all evaluated traits. 4. The current breeding strategies 
      accounting for additive genetic effect seem to be suitable for egg quality traits 
      in meat-type quail.
