Introduction Eggs contain many vital nutrients. Therefore, eggs are produced all over the world. Egg quality is determined by its consumer acceptance with respect to several characteristics including cleanliness, freshness, surface area, mass, volume

Dietary effects of Ca-zeolite supplementation on some blood and tibial bone characteristics of broilers

Effect of cage tier and age on performance, egg quality and stress parameters of laying hens

Comparison of meat quality and fatty acid profile in slow-growing chicken genotypes fed diets supplemented with Origanum vulgare or Melissa officinalis leaves under the organic system

The objective of this study was to determine the effects of eggshell color of guinea fowl (Numida meleagris) eggs on eggshell quality and hatchery results. The highest mean grey value (MGV), integrated density (ID), lightness (L*) and Hue angle (H*) values were obtained in eggs with lighter eggshell color. The effects of color difference (DE*) value levels on egg characteristics were evaluated. Eggshell color presented different (p<0.01) MGV, ID, L*, redness (a*), yellowness (b*), H* and Chroma (C*) values. Eggs with lighter color presented thicker eggshells and lower egg weight loss on day 25 of incubation (p0.05). In conclusion, under the conditions of the present study, eggshell color influenced eggshell thickness and weight loss, but not hatching parameters of guinea fowl eggs. Further studies on this subject should be carried out.
