Abstract

The present study was conducted to evaluate some parameters of external and internal egg quality of some pure dual chicken breeds. A total of 500 eggs (100 eggs from each breed) were collected to study for egg (weight, shape index), albumen (weight, percentage), yolk (weight, percentage) and shell (weight, percentage, thickness, strength) quality. The eggs were analysed in the laboratory of Department of Poultry Science and Small Animal Husbandry of Slovak University of Agriculture in Nitra. The results showed that the egg weight and egg length of New Hampshire were significantly higher (P 0.05). Differences in albumen weight, albumen percentage, yolk weight and yolk percentage of tested dual chicken breeds were statistically no significant (P>0.05). Albumen height was significantly higher (P 0.05) in egg shell thickness and strength.

Highlights

Gardini and Villa (2003) recorded that local breed are an evidence of great achievement of many generations of breeding
An increasing number of local chicken breeds are under threat of extinction, and valuable genotypes and traits are at risk of being lost (Blackburn, 2006; Dávila et al, 2009)
In the present study it has been observed that New Hampshire has significantly (P < 0.05) higher albumen height than Plymouth Rock Buff and Sussex Light

Summary

Introduction

Gardini and Villa (2003) recorded that local breed are an evidence of great achievement of many generations of breeding. An increasing number of local chicken breeds are under threat of extinction, and valuable genotypes and traits are at risk of being lost (Blackburn, 2006; Dávila et al, 2009). Egg quality is factor which contributes for better economy price of fertile and table eggs. Egg quality is factor which contributes for better economy price of fertile and table eggs (Kocevski et al, 2011). From the point of view of consumers, egg weight is the most important quality trait. The internal quality of egg is very important from the consumers’ point of view but it cannot be assessed without breaking the egg. The interior of hens egg consists of the yolk and white or albumen. The present study was conducted to evaluate of external and internal egg quality of New Hampshire, Oravka (Slovakian breed), Plymouth Rock, Rhode Island Red and Sussex Light chicken breeds
