“…Although there were differences in SFA content (P = 0.0019), they were of minor practical importance. This finding is in agreement with results of other authors (Cabrera et al, 2006;Milinsk et al, 2003;Pardio et al, 2005). Cabrera et al (2006) related this finding to the generally lower absorption of SFA and the fact that hens tend to maintain an optimal saturated: unsaturated FA ratio for growth and hatchability of chicks.…”

“…The difference in lipid content per 100 g of yolk was not significant (P = 0.6721). The results were similar to those reported by Milinsk et al (2003), but seem to be in disagreement with the results obtained by Cabrera et al (2006), who noticed that yolk weight has been significantly affected by the addition of sunflower and rice oils. No mortality of hens occurred during the trial, with the exception of one hen that died in the 5th week of the experiment.…”

“…The same results have been obtained in experiments with laying hens. Introducing elevated amounts of different PUFAs and conjugated fatty acids (CLAs) in feed resulted in the elevated amount of these FAs in eggs (Cabrera et al, 2006;Cherian, Traber, Goeger, & Leonard, 2007;Pardio et al, 2005). Several studies reported that linseed oil (LO) based diet gave the highest concentration of n-3 PUFA in yolk (Baucells, Crespo, Barroeta, Lopez-Ferrer, & Grashorn, 2000;Pita, Carvalho, Neto, and Mendonca Junior, 2010;Oliveira et al, 2010).…”

“…Therefore, the higher palmitoleic content in the eggs from hens fed the MBM + TA diet followed those from hens fed MBM + SO diet and reflected the palmitic acid content in these diets, as shown in Table 2. Cabrera et al (2006) also observed higher palmitoleic acid in yolks from hens fed animal fat sources (TA and pressed-fat of bovine viscera) than those from hens fed vegetable sources (sunflower and rice oils).…”

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.
