| Description: |
Although the nutritional value of eggs in human nutrition is well known, efforts are still being made to increase it. That can be achieved by selecting nutrients and supplements for laying hens feed rations. The aim of this study was to examine the effect of different amounts of flaxseed oil in the diet of laying hens on the fatty acid composition of eggs. To achieve that goal, experimental groups (three groups) of laying hens were supplemented with 1.5%, 3% and 4.5% flaxseed oil (as a substitute for corn). The control group of laying hens was fed without the addition of flaxseed oil. Feed rations were formulated according to recommendations for the ISA Brown hybrid. Each group comprised 40 individuals raised in the same conditions. Samples for analysis of the fatty acid composition of eggs were taken on days 14, 35 and 70 of the experiment, which lasted 10 weeks (from week 23to week 32). The fatty acid composition of eggs was examined using a standard procedure. On all days of the study (days 14, 35 and 70), the content of SFA was higher in eggs of the control groups of laying hens than in experimental groups and decreased with an increase in the amount of flaxseed oil in the feed. The content of MUFA was higher in the eggs of experimental groups of laying hens than in the eggs of the control group on all days of the study. The content of PUFA was found to increase with an increase in the amount of flaxseed oil in feed rations given to experimental groups and was higher than in the control group of laying hens. The ratio of n-6/n-3 fatty acids, as the most important indicator of nutritional value of any food, including eggs, was significantly more favorable on all days of the study in the eggs of experimental groups of laying hens than in the eggs of the control group. The use of flaxseed oil in the diet of laying hens can increase the nutritional value of eggs to such an extent that eggs produced in that way can be declared functional food. ; Zbornik kratkih sadržaja |
