Relationships among Some Quality Characteristics in Broiler Hatching Eggs

Türkçe

Relation among some parameters used for determining egg quality was studied in this research . Egg weight (EW), egg length (EL), egg width (EWd) and shape index (SI) was the studied parameters. A total of 1920 hatching eggs which were obtained from middle-aged (39 week) broiler breeders were used. In the first stage of this study, EW, EL, EWd were measured and SI values were calculated from these parameters. Average EW was 64.40 ± 0.04 g, EL was 57.35 ± 1.31 mm, EWd was 44.81 ± 0.61 mm and SI was 78.19 ± 0.10 in eggs of this study. In the second stage, coefficients of variation, correlation coefficients and regression equations were calculated for determining of relations among these parameters. Significant (p < 0.05) and significant correlation levels among EW and EL and EWd were determined (r = 0.582 and 0.734, respectively). Meanwhile, significant and high coefficient correlation among EW and SI was not found (p > 0.05) like egg width and egg length. Meanwhile, it was determined that egg width was more important variable than egg length and shape index for estimation of egg weight. Also, it was found that egg weight value could be estimated in higher accuracy by using egg width values instead of egg length and shape index values.
