Dietary Supplementation with Different ω-6 to ω-3 Fatty Acid Ratios Affects the Sustainability of Performance, Egg Quality, Fatty Acid Profile, Immunity and Egg Health Indices of Laying Hens

The supplementation of different ω-6/ω-3 ratio to the diets laying hens has been studied evaluate effects on performance, egg quality, health indices, fatty acid profiles, and immune response. One-hundred twenty, 50-weeks-old were divided into three groups fed with polyunsaturated acids (PUFA) at ratio: 16.7:1, 9.3:1, 5.5:1, respectively. Each group contained eight replicates five hens. Hens diet highest had significantly increased weight gain compared those 5.5:1 9.3:1 ratios. In contrast, ratios laid more eggs, mass, greater livability, a better FCR than control group. However, PUFA showed improved thrombogenic, atherogenic, hypocholesteremia, hypocholesteremia/hypercholesteremia indices. conclusion, while enriched ω-3 in eggs boosted response
