Sažetak:
The aim of this study was to investigate the nutritional composition of commercial eggs from Lohman Brown hens through fat and fatty acid content analysis, as well as to evaluate the effect of hen age on the above parameters. Egg samples (n=108) were collected every two weeks from 21- to 55- week old hens during the 2015/2016 autumn/winter period. The results revealed significant differences in fatty acid composition dependent on hen age (p < 0.05). When comparing eggs from the youngest, against those from the oldest hens, total saturated fatty acids (SFA) were found to be statistically significantly higher in the youngest hens (p < 0.05), whereas individual SFA shares did not statistically significantly differ between the two (p > 0.05). The total polyunsaturated fatty acid (PUFA) content was statistically significantly higher in eggs laid by 55- week old hens as compared to those laid by 21- week old hens. The n-6/n-3 and PUFA/SFA ratios were more favourable in the elder hens. In general, the results revealed hen ageing-based variations in fatty acid composition of their eggs, in particular in the representation of linoleic (LA), alpha-linolenic (ALA) and arachidonic acid (AA), for which statistically significant hen age-based differences were found.
