The effect of supplementation ARA oil on production performance, egg quality, fatty acid composition in laying hens were examined on this study. The aims on this study to producing ARA enriched eggs to meet infant nutrition requirements. A total of 450 Roman White laying hens with a similar egg production rate and good body condition at 55 weeks of age were randomly divided into 5 treatments. Each treatment was replicated 6 times with 15 hens per replicate.  Hens were fed basal diets with 0, 2,5%, 1,25%, 0,625%, and 0,3125% ARA oil addition. The supplementation ARA oil was effect to decreased egg production, egg weight, egg mass, daily feed intake and FCR (P<0.05) during 9-12 week, but on egg quality parameters showed slightly changed during the 1-12 week but not consistency and that change was not statistically significant. Arachidonate acid (ARA) was increased by supplementation ARA oil (P<0.05). This effect was detected in directly proportional to the addition of ARA oil on diet. This is opposite effect to DHA, DHA was decreased by supplementation ARA oil (P<0.05) and also effect to ratio ARA/DHA was increased (P<0.05) by supplementation ARA oil.

Laying Performance

The objective of this study was to determine the effects of diet supplemented with marigold on egg yolk fatty acid composition and egg quality parameters. Sixty hens were assigned into three groups and fed diets supplemented with 0 (control), 10 g kg−1, or 20 g kg−1marigold for 42 days. Eggs collected at the 6th week of the study were analyzed for fatty acid analysis. Laying performance, egg quality parameters, and feed intake were also evaluated. Yolk color scores in the group fed the 20 g kg−1marigold-supplemented diet were found greater than control (10.77 versus 9.77). Inclusion of 20 g kg−1marigold in diet influenced egg weights adversely compared to the control. Diet supplemented with 10 g kg−1or 20 g kg−1marigold increased the levels of C16:0 and C18:0 and decreased levels of C16:1 (n-7) and C18:1 (n-9) in the egg yolk. Also, diet including marigold increased total saturated fatty acids (SFA) and decreased monounsaturated fatty acids (MUFA) in the egg yolk.

Algal Oil

AbstractThe aim of this study was to evaluate the effect of algal oil with very high level of docosahexaenoic acid (DHA, C22:6n-3) used as fat source in the diet for laying hens, on egg yolk lipids fatty acid composition, as well as egg production and egg quality indices, in comparison with other dietary fat sources. The experiment was carried out on 168 ISA Brown hens (25 to 60 wks of age), allocated to 7 groups of 12 replicates (cages), with two birds in each cage. The experimental diets were supplemented with 2% of different fat sources, i.e. soybean oil (SO), coconut oil (CO), rapeseed oil (RO), linseed oil (LO), camelina oil (CAO), fish oil (FO), or algal oil (AO). Laying performance indices, i.e. egg production, mean egg weight, feed intake, feed conversion ratio, or egg and eggshell quality parameters were not affected by used fat sources (P>0.05). Dietary fat sources significantly influenced on egg yolk lipids fatty acids composition. Thus, AO addition caused some changes in the yolk lipid profile that were favorable from the dietary perspective, i.e., increased concentration of eicosapentaenoic acid (EPA) and DHA (P<0.05). However, boiled eggs from hens fed a diet with AO were characterized by an inferior flavour and taste to those from other groups. In conclusion, the results of this experiment, have shown that the use of AO in the laying hens nutrition is an efficient way to increase the deposition of n-3 long chain polyunsaturated fatty acids (n-3 LCPUFAs) in eggs, without negative effect on egg performance, however further researches, aiming to establish optimal AO dietary level that does not adversely affect the organoleptic properties of eggs, are needed.

Mealworm Larvae

The purpose of this study was to investigate the effects of different levels of mealworm (Tenebrio Molitor) larvae meal in Japanese quail (Coturnix coturnix japonica) diets on performance, egg quality, yolk color, and yolk fatty acid composition. A total of forty-eight, 14 weeks-old laying quails were used with 4 replicates in control (basal diet), mealworm larvae meal (MLM) 2% or 4 % treatment groups. Results showed that independently of inclusion level dietary MLM did not affect performance and egg quality parameters. However, color values (L*, a*, b*) of egg yolk changed with the inclusion of both levels of MLM to diet (p<0.5). Outcomes also displayed dietary MLM altered the fatty acid composition of egg yolk dependably the additional level (p<0.5). Diets containing 2 and 4 % MLM did not affect total saturated fatty acid (ƩSFA) content, however, increased total monounsaturated fatty acids (ƩMUFA) (p<0.5). Both supplemental levels of dietary MLM decreased significantly the total polyunsaturated fatty acids (ƩPUFA) of the yolk compared to the control group (p<0.5). According to outcomes of this study, MLM may use in safe as feed material instead of soybean meal at levels of 2 or 4 % without effect on performance parameters in laying quail diets.
