“…The average of eggshell thickness in this study ranged from 0.409 to 0.430 mm, and the eggshell strength ranged from 3.43 to 4.62 kg/cm 2 . These results were similar to that reported by An et al (2019) who found eggshell thickness and eggshell strength of eggs from laying hens fed with lycopene or tomato paste were 0.35-0.36 mm and 4.39-4.74 kg/cm 2 , respectively.…”

“…The inclusion of boiled tomato waste powder in laying hens diet did not affect Haugh unit, eggshell thickness, and eggshell strength of laying hens (Table 3). It has been reported that the inclusion of lycopene in laying hens diet did not have an effect on the Haugh unit (Honda et al, 2019;An et al, 2019). The average Haugh unit of laying hens in this study ranged from 69 to 81.…”

This study was performed to evaluate the effect of inclusion of boiled tomato waste powder in laying hens diet on growth performances and egg quality. Tomato waste used in this experiment was surplus and unsold mature tomato from the last harvest on the field. The tomato waste was boiled in boiling water (100 ºC) for 8 minutes to convert their lycopene structure from trans to cis, which is easily absorbed by the poultry digestive tract. In a completely randomized design, 200 Isa Brown laying hens were divided into five groups with different inclusion levels of boiled tomato waste powder (0, 3, 6, 9 and 12%) in an iso-nitrogenous (16%) and iso-caloric (2600 kcal/kg) diet. Daily feed intake, hen day egg production, egg weight, egg mass, feed conversion ratio, eggshell thickness, and eggshell strength were measured. The obtained results showed that boiled tomato waste powder in the diet did not significantly affect daily feed intake, feed conversion ratio, egg production and egg quality. In conclusion, the tomato boiled powder could be used up to 12% in laying hens diet with no effect on performance and egg quality of laying hens.

“…Only carotenoids that do not have provitamin activity, including lycopene (Imran et al, 2020) and astaxanthin (Davinelli et al, 2018), are able to accumulate in chicken egg yolks, while β-carotene is transformed into vitamin A, which although it enters the yolks of chicken eggs, does not affect their colour (Shevchenko et al, 2017a). Feeding laying hens with oil extracts of lycopene and astaxanthin in different doses for 90 days did not affect the indicators characterizing their quality, namely egg weight, albumen height, Haugh unit, strength and shell thickness, which is consistent with the results of studies by An et al (2019). Previous studies have also shown that carotenoids on the example of β-carotene have a positive effect on the morphological parameters and chemical composition of quail eggs (Shevchenko et al, 2017b).…”

Ensuring an attractive commercial appearance of egg yolks involves the introduction to the feed of laying hens of the dyes of various origins. Recently, egg producers have preferred natural dyes, which include carotenoids: lycopene and astaxanthin, which can be deposited in chicken egg yolks. The aim of this study was to determine the quality of egg yolks, colour intensity and carotenoid composition of yolks when oil extracts of lycopene (20, 40 and 60 mg/kg feed) or astaxanthin (10, 20 and 30 mg/kg feed) are included in the chickens’ diet. 45 High Line W36 chickens at the age of 24 weeks were used for the experiment. Feeding laying hens with supplements of lycopene oil extracts at doses of 30, 40 and 60 mg/kg and astaxanthin at doses of 10, 20 and 30 mg/kg of feed for 30 days in increasing concentrations did not affect egg weight, albumen height, Haugh unit, strength and the thickness of the shell. The addition of lycopene to the diet of chickens at doses of 20 mg/kg of feed increased the content of lycopene, unidentified carotenoids and the total content of carotenoids in the yolks, but did not change the intensity of their colour. Increasing the dose of lycopene in the diet of chickens to 40 and 60 mg/kg of feed increased the content of lycopene in yolks and the intensity of their colour to 7.4 and 8.0 points against 5.6–6.1 points in the control, but did not affect the content of β-carotene and total carotenoids in the yolks. The addition of astaxanthin oil extract at doses of 10, 20 and 30 mg/kg of feed increased the content of astaxanthin, β-carotene and total carotenoids in chicken egg yolks and increased the intensity of their colour to 12.8, 14.8 and 14.4 points on a 16-point colour scale YolkFanTM. To obtain chicken table eggs with a given colour of the yolks, it is advisable to use the addition of astaxanthin oil extract in doses from 10 to 20 mg/kg of feed for 30 days. The results of the research can be used to develop a technology for the production of functional table eggs enriched with carotenoids of natural origin with an attractive colour for consumers.

“…In particular, there was a significant interaction between the effects of breed and diet on lutein content, which showed that the combination of MA dietary treatment and the SF breed resulted in a higher accumulation of lutein in the yolk. Feeding lutein to laying hens enhances hepatic SOD activity (Jang et al, 2014), while feeding them with lycopene increases yolk oxidative stability (An et al, 2019). The present study revealed similar findings, although the carotenoid types were dissimilar.…”

The effects of dietary carotenoids on egg yolk were investigated in this study. Forty Rhode Island Red (RR) and 40 Silky Fowl (SF) hens that were 60 weeks old were used. Hens of each breed were randomly divided into four dietary groups. One group was fed a basal diet (crude protein 17%, metabolizable energy 2800 kcal/kg) only, whereas the other groups received a specific additive, namely, paprika extract, marigold petal extract, or Paracoccus cell powder, in addition to the same basal diet. The color and carotenoid content of egg yolk and singlet oxygen quenching activity were measured after 4 weeks.The total carotenoid content, zeaxanthin content, and singlet oxygen quenching activity in the yolk differed significantly between breeds and between diets (two-way ANOVA).The lutein content in egg yolk was affected by breed and diet, as well as by the interaction between these two factors. Regarding the Roche Yolk Color Fan values, only the effect of diet was significant. In terms of objective egg yolk color, there was a significant difference in lightness and yellowness between breeds. The total carotenoid content was higher in SF than in RR in all the groups. Likewise, the levels of zeaxanthin and lutein in the yolk were higher in SF than in RR (P < 0.05). The results of the present study suggest that dietary carotenoids are effective feed additives for laying hens, especially SF, to improve the color and singlet oxygen quenching activity of egg yolk.
