Chemical composition of eggs for consumption from laying hens raised in two different breeding systems
Session
Agriculture, Food Science and Technology
Description
To study the influence on the chemical composition of eggs from hens breeding in two breeding systems: the intensive system in cages and in the extensive system in yards, 54 samples of hens' eggs were analyzed from 18 different farms from both systems in the Peja Region in Kosovo. Eggs were analyzed for chemical components such as water, total nitrogen, protein, fat, energy and ash content. It turned out that egg samples from free home breeding have higher values of chemical components than egg samples from industrial breeding in protein (13.83% vs. 12.93%), total nitrogen (2.21% vs. 2.07%), fat (14.13% vs. 8.87%), energy (186.7 Kcal against 134.84 Kcal) and ash (0.98% against 0.88%). It seems that the changes in the content of chemical components in the researched egg samples were influenced by breeding, environmental, climatic, stressful and nutritional factors, which are different in the two breeding systems of hens for eggs, especially in the winter period when the study was carried out.
