Öğe Effect of adding linseed and selenium to diets of layer hen's on performance, egg fatty acid composition and selenium content(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Gurbuz, Emel; Balevi, Tahir; Coskun, Behic; Citil, Ozcan BarisIn a 4x3 factorial experiment, six hundred 31-week-old laying hens were fed diets containing 0, 25, 50 and 100 g/kg linseed with control, 0.3 mg/kg organic selenium (OrSe) and 0.3 mg/kg inorganic selenium (InSe) to determine the effects of diet on performance, eggshell parameters, egg fatty acid composition and selenium (Se) content of eggs. Laying hens were randomly assigned to 12 experimental groups with 5 replications. Linseed supplementation decreased egg production (d 1-30), feed consumption (d 1-30 and 1-90) and egg weight (d 60-90 and 1-90). Shell weight and thickness decreased when dietary linseed was increased. There were interactions between Se and linseed in feed consumption, feed efficiency, damaged egg ratio and shell thickness. The inclusion of InSe and OrSe increased the Se content of the eggs. Docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), alpha-linolenic acid (ALA) and n-3 fatty acid concentrations in egg yolks increased with increasing dietary linseed. There were also interactions between linseed and Se in ALA and n-3 fatty acid concentrations. In conclusion, the addition of linseed to the diets increased DHA, EPA, ALA and n-3 fatty acid concentrations in egg yolks, and the addition of Se increased the Se content of the eggs. Egg fatty acids (ALA, n-3 fatty acid) were increased by supplementing dietary linseed with OrSe.Öğe The effects of dietary flaxseed oil supplementations on fatty acids composition of the yolks in quail (coturnix coturnix japonica) eggs(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2011) Citil, Ozcan Baris; Yildirim, Iskender; Parlat, Sinan SefaThis experiment was carried out to determine effects of Japanese quail diets which is supplemented with different levels of omega-3 fatty acids compositions in yolk. In this study, one hundred-twenty laying quails at 10 weeks of age (Coturnix coturnix japonica) were used. They were divided into 4 tretament groups, each group included 30 quails. The diets in treatment groups contained different levels of flaxseed oil 0, 1.0, 2.0, and 3.0%, respectively. At the end of the experiment lasted for 21 days, 7 eggs taken from each group were subjected to analysis. The fatty acid compositions of egg yolks were determined by gas chromatography. Twenty seven different fatty acid components were determinated in the compositions of quail egg yolks. No differences were found in oil content among the groups. The increased ingestion of linolenic acid in diet reduced the formation of arachidonic acid in egg yolks of the treatment groups. The omega-3 fatty acid levels were higher in all treatment groups than that of control group. Supplemental flaxseed oil at the level of 3% increased the concentration of omega-3 in egg yolk. At the end of the experiment, the omega-3/omega-6 ratio increased from 0.05 (control) to 0.18 (3.0%). It was observed that when flaxseed oil amounts was increased in quail rations, omega-3 fatty acid amounts in egg yolk was improved.Öğe THE EFFECTS OF SEASONS ON CHOLESTEROL CONTENT AND FATTY ACID COMPOSITIONS OF MUSCLE OF HELIX ASPERSA LIVING IN KONYA, TURKEY(AFRICAN NETWORKS ETHNOMEDICINES, 2014) Citil, Ozcan Baris; Tekeli, Yener; Danahaliloglu, Hatice; Bucak, SerbayBackground: The aim of the present study is the determination of the effects of seasonal variations on the proximate analysis, cholesterol content and fatty acid compositions of Helix aspersa. Materials and Methods: Garden snails (Helix aspersa) were picked up by hand from the Central Anatolia Region of Turkey, in autumn (November) and spring (April) in 2011. Fatty acid methyl esters (FAMEs) and cholesterol analysis were analyzed by gas chromatography (GC). The protein contents of snail muscle were determined with Kjeldahl distillation units. Statistical comparisons were made by using SPSS Software (version 16.0). Results: Thirty different fatty acids of different saturation levels were detected. As the predominant fatty acids, stearic acid (C18:0), oleic acid (C18:1 omega 9), linoleic acid (C18:2 omega 6), palmitic acid (C16:0), arachidonic acid (C20:4 omega 6), eicosadienoic acid (C20:2) and linolenic acid (C18:3 omega 3) were found in Helix aspersa. Palmitic acid (C16:0) was identified as the major SFA in autumn and spring. Linoleic acid (C18:2 omega 6), eicosadienoic acid (C20:2) and arachidonic acid (C20:4 omega 6) have the highest levels among the PUFAs. In the present study, omega 3 were found 5.48% and 13.94% in autumn and spring, respectively. Conclusion: Linolenic acid and omega-3 fatty acid amounts in the spring increased significantly but cholesterol content was not affected in Helix aspersa both in season.Öğe Effects on Fatty Acid Compositions of Muskule Grape Leaves (Vitis vinifera L.) of Different Harvest Times(ASIAN JOURNAL OF CHEMISTRY, 2012) Akin, Aydin; Citil, Ozcan BarisThe present study, deals with the fatty acid profile in six different harvest times of Muskule grape leaves grown in Turkey. The fatty acid profile was determined using gas chromatography. Twenty eight fatty acids were detected in grape leaf oils. Generally, C 18:1 oleic acid, C 14:0 myristic acid, C 18:0 stearic acid, C 18:2 omega 6 linoleic acid, C 16:0 palmitic acid and C 18:3 omega 3 linolenic acid were found to be the major fatty acids in all dates. The monounsaturated fatty acids were determined at 37.43, 41.43, 45.18, 50.05, 51.75 and 54.96 % in 16.05.2010, 31.05.2010, 16.06.2010, 03.07.2010, 20.07.2010, 07.08.2010, respectively. Monounsaturated fatty acids content was found to be more than the polyunsaturated fatty acid content in all times. Despite of the saturated fatty acid showed a decrease against time; there was an increasement with the monounsaturated fatty acids.
