“…Quirino et al (2009) recorded 33.23% lipid content in yolk after the addition of soybean oil. Hayat et al (2009) found that the total lipid content was higher after flaxseed addition compared to the control group, as we did in our trial. In a study by Ansari et al (2006), flaxseed supplementation (0, 5, 10 and 15% of the diet) did not affect the total fat content of the yolks at any level.…”

The aim of this study was to determine the effect of pumpkin and flaxseed oils on the fatty acid profile and nutrient changes in table eggs. At 38 weeks of age, Lohmann Brown Lite hens were divided into three groups depending up the diet. The birds were housed in individual cages (6 hens per cage) with a space allowance of 943.2 cm 2 per hen, and given diet standard complete feed mixture for laying hens. Hens from experimental groups were fed with complete feed mixtures supplemented by pumpkin (group E1) or flaxseed (group E2) oils at a dosage of 3%. The experiment lasted 52 days. In the last week of the trial, the eggs were collected for chemical analysis. Twelve eggs from each dietary treatment were randomly selected and analysed. Significant differences between control and group E1 in the content of crude protein (P ˂ 0.05), between both experimental groups (E1 and E2) in the content of ash (P ˂ 0.01) in yolk, and between control and the experimental groups in the content of dry matter (P ˂ 0.05) in albumen were detected. Significant (P ˂ 0.01) differences were found in contents of myristic, palmitic, heptadecanoic, oleic, linoleic, and cis-11,14-eicosadienoic acids between control and experimental groups E1 and E2. Compared to control, higher (P ˂ 0.01) concentrations of monounsaturated fatty acids, lower concentrations of saturated fatty acids and also lower contents of polyunsaturated fatty acids in the experimental groups were observed. The supplementation of flaxseed oil had a positive effect on the content of n-3 α-linolenic acid. Albumen, laying hens, nutrients, plant fats, yolk

“…The laying hens in all dietary treatment groups consumed a similar amount of feed throughout the trial, which suggests that there was no palatability problem or inhibitor effect such that reported when the diets were supplemented with high levels of flaxseed (Hayat et al, 2010). Furthermore, including purslane meal into the diets did not influence FCR, which is similar to the reports of previous studies in which ALA rich sources such as flaxseed (Hayat et al, 2009;Al-Nasser et al, 2011) or flaxseed oil (Mazalli et al, 2004;Kartikasari et al, 2014) were supplemented in the diet.…”

“…Purslane were not affected by the supplementation of dietary ALA, suggesting that the use of 6% purslane meal as a source of ALA can be applied without affecting physical egg quality. The absence of an effect on egg weight by high ALA diets is in accordance with the previous studies (Grobas et al, 2001;Hayat et al, 2009, Kartikasari et al, 2014, using purslane may be associated with the amount of feed intake (Nobakht, 2014). In addition, Evaris et al (2015) reported that diets supplemented with 200 g/kg purslane meal did not affect egg quality.…”

“…This strategy rests on the ability of laying hens to convert ALA to DHA. Some researchers reported that the n-3 fatty acid level of eggs increased by adding plant sources of n-3 PUFA (ALA), such as flax seed (Hayat et al, 2009), hemp seed (Gakhar et al, 2012) or chia seed (Ayerza, 2009). For example, the inclusion of 10% flaxseed (~33% ALA) in the diets of laying hens resulted in a higher accumulation of n-3 fatty acids than a control diet (Bean and Leeson, 2003).…”

Abstract. The aim of the study was to evaluate the effects of inclusion plant source of n-3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the diets of layers on production performance and physical quality of eggs. A total of 125 Hy-Line Brown hens (38 weeks old) were placed at individual cages and assigned to five dietary treatments. The dietary treatments were supplemented with 0, 1.5, 3.0, 4.5 and 6.0% purslane meal. Laying hens were fed for five weeks following a seven day adaptation period. Water and feed were provided ad libitum. Feed intake (FI) measured weekly and feed consumption ratio (FCR) was calculated at the end of the trial. A total of 25 egg yolk samples of day 35 (n = 5 egg yolks for each treatment) were collected to analyse physical quality of eggs. The data were analyzed using analysis of variance. Differences between treatment means were further analyzed using Duncan's New Multiple Range Test (DMRT). Results showed that the incorporation of plants rich in ALA did not modify FI, FCR, and egg production. Supplementation of purslane meal in the diets had no effect on physical quality of eggs, including egg weight, yolk weight, albumen index, yolk index and Haugh Unit (HU). The average of egg weight and yolk weight were 60,5 and 15.3 g, respectively. Diet containing purslane meal increased yolk colour. In conclusion, laying hens that fed diet supplemented with purslane meal rich in ALA improved yolk colour and did not change the production performance of the laying hens or the qualities of the eggs. Key words: Portulaca oleracea, alpha-linolenic acid, production performance, egg qualityAbstrak. Tujuan dari penelitian ini adalah mengetahui pengaruh lemak n-3 dari tanaman dalam bentuk alphalinolenic acid (ALA, 18:3n-3) pada pakan ayam petelur terhadap performa produksi dan kualitas fisik telur. 125 ayam Hy-Line Brown (38 minggu) ditempatkan pada kandang terpisah dan diberi 5 perlakuan pakan yang diberi tambahan 0, 1,5, 3,0, 4,5 dan 6,0% tepung krokot. Ayam petelur diberi pakan selama 5 minggu dan 7 hari adaptasi. Pakan dan air diberikan ad libitum. Asupan pakan (FI) diukur setiap minggu dan rasio konsumsi pakan (FCR) dihitung pada akhir percobaan. Sejumlah 25 sample kuning telur pada hari ke 35 (n= 5 kuning telur dari setiap perlakuan) diambil untuk dianalusa kualitas fisiknya. Data dianalisa menggunakan Analysis of Variance (ANOVA). Perbedaan antara perlakuan kemudian dilanjutkan dengan Duncan's New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa suplemen tanaman kaya ALA pada pakan tidak mempengaruhi kualitas fisik telur, termasuk berat telur, berat kuning telur, indeks albumen, indeks kuning telur dan Haugh Unit (HU). Rataan berat telur dan berat kuning telur berturut-turut adalah 60.5 dan 15.3. Pakan mengandung tepung krokot meningkatkan warna kuning telur. Disimpulkan bahwa ayam petelur yang pakannya disuplementasi dengan tepung krokot yang kaya ALA meningkatkan warna kuning telur tetapi tidak mengubah performa produksi ayam telur atau kualitas telur.

This study aimed to determine the effect of different dietary level of rice bran extract (RBO) on the laying performance, egg quality, blood parameter, cholesterol, and fatty acids in yolk of Hy-Line Laying hens. In all, 144 Hy-Line Brown laying hens (29 weeks old) were randomly allocated to one of 4 dietary treatments, with 4 replicates per treatment. A commercial basal diet was used and three additional diets were prepared by supplementing 2.5, 5.0 or 10.0 g/kg of RBO to the basal diet. The experimental diets were fed on an ad libitum basis to the bird during 8 weeks. Hen-day egg production increased (quadratic, p<0.05) with inclusion level of RBO, but feed intake, egg weight, and egg mass were not influenced by inclusion of level of RBO in diet. However, the supplementation of RBO did not have an effect on eggshell strength, eggshell thickness, egg yolk color, and HU during the feeding trial. There were no significant differences in the level of leukocyte. However, heterophil and lymphocytes decreased (quadratic, p<0.01) with inclusion level of RBO. H:L ratio tended to decrease (linear p=0.08) with inclusion level of RBO. As expected, increasing inclusion level of RBO in diets decreased (linear, p<0.01) the concentrations of total cholesterol in plasma. AST, ALT, glucose, and albumin were not affected by inclusion of RBO in diets. Egg yolk cholesterol increased (linear and quadratic, p<0.05) with inclusion level of RBO in diet. The results of this study indicate that dietary supplementation of RBO improves laying performance and decreased total cholesterol and egg yolk cholesterol levels in laying hens. Therefore, dietary RBO is considered a valuable functional ingredient to improve the performance of birds.
