“…Egg qualities, i.e., eggshell strength, thickness, or Haugh unit were not affected by dietary treatments as reported previously (Kim et al, 2008;Rotolo et al, 2010;Akdemir et al, 2012). In contrast to our findings, dietary LP at 100 or 200 ppm linearly increased Haugh unit in quails (Sahin et al, 2008). Here we confirmed the well-established LP effect on intensifying yolk color, which is the consequence of direct incorporation of LP into the egg yolk, as seen in this study and reported elsewhere (Kim et al, 2008;Sahin et al, 2008;Rotolo et al, 2010;Akdemir et al, 2012;Sun et al, 2014a).…”

“…It is known that LP-enriched eggs were inversely associated with a decrease in MDA contents in egg yolks (Sahin et al, 2008) due to the role of LP as a natural antioxidant (Di Mascio et al, 1989). Similarly, we found that a decreased serum or egg yolk MDA content was observed in both LP20 and TP17 groups, compared with the control group.…”

“…For example, no effect of dietary LP on laying performance in Chinese native breeding hens (Sun et al, 2014a) or commercial hybrid laying hens (Kim et al, 2008;Rotolo et al, 2010) was reported. However, Sahin et al (2008) and Akdemir et al (2012) noted that dietary LP or tomato-related products increased feed intake and egg production with the increasing LP supplementation in Japanese quails or laying hens. Sahin et al (2006b) observed that dietary LP at 100 ppm did not affect feed intake and egg weight, but increased egg production in Japanese quails.…”

“…Previous studies focused on the impact of LP on the blood lipid profiles, hosts' antioxidant systems or oxidative stability of poultry meats (Dotas et al, 1999;Olsen et al, 2008;Sahin et al, 2008;Akdemir et al, 2012;Sun et al, 2014a). However, there is a lack of research into the oxidative stability of eggs under long-term storage conditions.…”

The present study was undertaken to investigate the effect of dietary, synthetic lycopene or tomato paste on laying performance and egg qualities in laying hens, and on lipid oxidation of stored eggs. One hundred and sixty 38-week-old Hy-line Brown laying hens were randomly housed in cages (two birds per cage, five cages per replicate) equipped with nipples and a trough-type feeder and subjected to one of four experimental diets. Each treatment had four replicates. A corn and soybean meal base diet was added with or without either synthetic lycopene to contain 10 or 20 mg per kg of diet, or with 17 g of tomato paste per kg of diet.The feeding trial lasted four weeks. Feed intake did not differ between dietary treatments.Laying hens fed diets containing lycopene or tomato paste laid lighter eggs (P<0.05) compared with those fed on the control diet. Egg production was higher (P<0.05) in tomato paste-fed layers, but lower (P<0.05) in those fed on a diet containing 20 mg/kg of lycopene compared with the control diet-fed counterparts. Dietary lycopene did not affect egg quality, except for yolk color, nor did serum lipid profiles. Malondialdehyde (MDA) content in serum samples and eggs that had been stored at 24°C for four weeks was reduced (P<0.05) by lycopene or tomato paste. Adding lycopene or tomato paste into a diet of laying hens increased the incorporation of lycopene into the liver and egg yolk. Collectively, the present study shows that addition of low levels of lycopene or tomato paste into the layers' diet is an effective nutritional strategy to enhance oxidative stability of fresh eggs.

This research aimed to examine the effects of fish oil and tomato powder supplementation on egg quality of Mojosari ducks. A total of one hundred and forty Mojosari ducks (consisted of 20 male and 120 female ducks), aged at 40 weeks old, were randomly allotted into 20 flocks (each flock consisted of 1 male and 6 female ducks). Method used was experiment in a Completely Randomized Design with 5 treatments and 4 replications. Dietary treatments used were T0: basal diet (control), T1: basal diet + 1% FO, T2: basal diet + 2% FO, T3: basal diet + 1% FO + 1% TP; T4: basal diet + 2% FO + 1% TP. Data were analyzed using one-way analysis of variance (ANOVA). Result showed that supplementation of fish oil and tomato powder did not significantly affect (P>0.05) external egg quality (egg shape index, shell surface area, shell thickness and specific gravity). Dietary treatments also had no significant effect (P>0.05) on internal egg quality (albumen volume, yolk volume, albumen index, yolk index and Haugh unit). It is concluded that there was no detrimental effect of fish oil and tomato powder supplementation in Mojosari ducks diet on external and internal egg quality.
