the present study was conducted to estimate correlations among performance and egg quality traits in iranian native fowl. data were collected from 21,679 birdsat the isfahan native fowl breeding center to derive genetic parameters for performance traits and egg quality traits were measured on eggs of 1,020 birds. genetic correlations of performance and egg quality traits were estimated with a b...

In order to assess the effects of the sinusoidal vibrations on indices that characterise the internal quality, five samples of 30 eggs were stressed for 5 h with a constant acceleration of 0 5 g (root mean square value, r.m.s.) at frequency linearly increasing with the time in the 5–20, 20–35, 35–50, 50–65 and 65–80Hz ranges (one range for each sample). Vibration tests were carried out by means...
