Abstract

This study was conducted to examine the effect on performance, egg quality criteria and egg cholesterol level of adding different ratios of flaxseed oil instead of sunflower oil to the compound feed of laying hens. A total of 210, 30-week old Lohmann LSL laying hens were acquired for the study. The study groups consisted of a control group (5% sunflower oil (SO) + 0% flaxseed oil (FO) and trial 1 (4% SO + 1% FO), trial 2 (3% SO + 2% FO), trial 3 (2% SO + 3% FO), trial 4 (1% SO + 4% FO) and trial 5 (0% SO + 5% FO) groups. The study lasted for 8 weeks. The feed consumption was not different among the experimental groups. Feed utilization rate was higher in group 2 compared to those of other between 0-8 weeks (P<0.001). Between weeks 0 to 8, all trial groups were found have significantly higher levels of linoleic acid, one of the fatty acids found in yolk, compared to the control group (P<0.001). Additives were not found to affects levels of cholesterol in yolk, with no significant differences found between groups. In short, sunflower oil and flaxseed oil added to laying hen rations did not create any differences in terms of egg quality criteria or egg cholesterol levels, but higher levels of flaxseed oil added to the rations resulted in linearly higher levels of linolenic acid content of yolk, and use of the two oil additives together increased egg yields.

Highlights

This study was conducted to examine the effect on performance, egg quality criteria and egg cholesterol level of adding different ratios of flaxseed oil instead of sunflower oil to the compound feed of laying hens
Of the saturated fatty acids, acetic and butyric acids are formed as the final products of carbohydrates; capric, caproic and caprylic acids are found in vegetable oils, and in very small concentrations, in butter; lauric acid is found in coconut oil, cinnamon, palm kernel, and bay leaf; myristic acid is found in coconut oil and palm kernel; and palmitic and stearic acids are found in all animal fats and vegetable oils (Ergün et al 2014)
Of the unsaturated fatty acids, palmitoleic acid and oleic acid are found in vegetable oils and animal fats; linoleic acid is found in sunflower seeds, soybeans, corn, peanuts, and cotton seeds; Altaçlı et al - Journal of Agricultural Sciences (Tarim Bilimleri Dergisi), 2022, 28(1): 107-114 linolenic acid is found in flaxseed oil and fish oil; and arachidonic acid is found in peanuts and animal phospholipids (Ergün et al 2014)

Summary

Introduction

This study was conducted to examine the effect on performance, egg quality criteria and egg cholesterol level of adding different ratios of flaxseed oil instead of sunflower oil to the compound feed of laying hens. Quality foods have balanced amounts of nutrients such as protein, fat, carbohydrate, minerals and vitamins, which can be found in foods of vegetable and animal origin in varying amounts. Animal products such as meat, milk and eggs play an important role in human nutrition, and there has been a growing trend in recent years to pay more attention to the quality of the food we consume. Of the unsaturated fatty acids, palmitoleic acid and oleic acid are found in vegetable oils and animal fats; linoleic acid is found in sunflower seeds, soybeans, corn, peanuts, and cotton seeds; Altaçlı et al - Journal of Agricultural Sciences (Tarim Bilimleri Dergisi), 2022, 28(1): 107-114 linolenic acid is found in flaxseed oil and fish oil; and arachidonic acid is found in peanuts and animal phospholipids (Ergün et al 2014)
