Special Issue Information

Dear Colleagues,

Poultry raw materials, irrespective of their geographic origin, stand as one of the most prevalent sources of animal protein in the human diet. The expanding scope of production and ongoing breeding endeavors endows this field with significance not only from an economic standpoint but also from the perspective of scientific investigation. The multitude of factors influencing the quality of eggs and poultry meat ensures that research on this subject grows constantly, thereby yielding fresh insights into bird physiology, breeding and rearing practices, as well as the conditions related to bird welfare.

The Special Issue, ‘Enhancing Product Excellence in Poultry: Key Factors Influencing Egg and Meat Quality’ invites submissions of original research articles or comprehensive review papers on all aspects that may impact the quality of poultry raw materials. Areas of interest encompass a broad spectrum of topics, including bird husbandry and breeding, modifications in feed additives and feeding programs, bird welfare, and the chemical composition of meat and eggs. Additionally, we encourage papers addressing the less common avian species classified as poultry.

In recent years, the free-range system for laying hens has increased, driven by societal sensitivity to animal welfare. This study aimed to comparatively analyze the total lipid, cholesterol, and fatty acid composition of egg yolks of late-age laying hens reared in enriched cages (C) and the free-range system (FR). Eggs were collected from Lohmann Brown Classic hens at the 68th, 70th, 72nd, and 74th week of age. The concentrations of total lipids and cholesterol were not affected (p > 0.05) by either factor. Egg yolk from the FR group showed lower (p < 0.01) monounsaturated fatty acids and higher (p < 0.01) polyunsaturated fatty acid (PUFA) compared with that of the C group. From a nutritional point of view, the PUFA n-6/n-3 and the PUFA/SFA ratios of egg yolk from the FR group were favorably lower and higher (p < 0.01) compared with the C one. Conversely, hen age did not affect (p > 0.05) the fatty acid composition of yolks. Interactions between factors were found for total n-3 and n-6 PUFA and the n-6/n-3 ratio (p < 0.01), as well as the thrombogenic index (p < 0.05). In conclusion, the results confirmed that the free-range system may improve the nutritional yolk fatty acid profile and its positive impact on human health. Full article
