“…The betalains from beetroot had no pigmentation effect on the lipids of the yolk possibly because of its hydrophilic chemical nature. Similar results were obtained by Kopriva et al (2014), who, when adding 1 to 2% of beet to the diets of laying hens, did not observe any effects on yolk colour.…”

Compounds such as pigments, antioxidants, and pro-vitamins A are found in carrots and beetroots and could increase the nutritional value of eggs when added to diets for laying hens. This research evaluated retinol concentrations and egg yolk colour with addition of freeze-dried carrot (Daucus carota L.) and beetroot (Beta vulgaris L.) meal in the diets of 240 Hisex Brown laying hens. The hens were distributed in a completely randomized design in five groups according to five experimental diets: (1) maize and soybean meal; (2) sorghum and soybean meal; (3) sorghum and soybean meal plus 0.8% of freeze-dried carrot meal; (4) sorghum and soybean meal plus 0.8% of freeze-dried beetroot meal; (5) sorghum and soybean meal plus 0.4% of freeze-dried carrot meal and 0.4% freeze-dried beetroot meal. The diet containing maize and soybean meal resulted in a more intense egg yolk colour and higher retinol levels in comparison to other diets (P < 0.05). However, carrot meal increased egg yolk colour and beetroot meal increased egg yolk retinol concentration in comparison to sorghum and soybean meal diets (P < 0.05). The inclusion of 0.8% of the carrot and beetroot meal in the diet is not enough to reach the intensity of yolk colour and yolk retinol concentration obtained through the diet containing maize, however, it increases retinol level and yolk colour in comparison to the diet containing sorghum without carrot and beetroot meal.

A rapid development in the potential use of phytogenic feed additives has occurred mainly due to the 2006 EU ban on the use of antimicrobial substances as growth stimulators; however, they are also used as sensory, technological additives or substances positively affecting the quality of animal products. The use of phytogenic additives in form of extracts, predominantly essential oils, has been tested in a number of animal species; however, there is still a lack of scientific findings on the safety and efficacy of their use, or on their effect on the quality of animal products. The aim of this review was to sum up current scientific knowledge on phytogenic additives in animal nutrition.

“…Changes in animals' feeding are the most commonly studied and applied way to modify meat properties and quality (Vieira et al, 2021;Gül et al, 2022). Earlier authors suggest that, due to the composition of red beets, their inclusion in poultry diets could modify productive performance and affect certain egg parameters, such as yolk color or antioxidant compounds (Kopřiva et al, 2014;Souza et al, 2019;Al-Waeli et al, 2021;Şengül, 2021). However, few researchers have investigated beetroot as animal feed, and the majority of recent work has focused on the application of beetroot as an additive in meat preparations (Domínguez et al, 2020).…”

The survey was carried out to establish the impact of red beet powder (RBP) on performance parameters and egg quality in laying quails. One twenty hundred (120) female laying quails aged 22 weeks were randomly assigned into five groups of 4 females each, and six replicates. Treatments diets were formed by adding 0, 0.2, 0.4, 0.6, and 0.8% RBP to the basal diet. The dietary inclusion of RBP did not affect performance parameters and egg production (P > 0.05) except feed conversion ratio, which was quadratically affected (P < 0.05). The feed conversion ratio was improved in the 0.4% group with concerning control. The inclusion of RBP did not modify the yolk color (L*, a*, b*) or egg quality (P > 0.05). However, the yolk index showed the highest value (P < 0.05) in quails fed 0.2% RBP. Free radical scavenging capacity (DPPH) of the yolk decreased (P < 0.05) when RBP levels increased above 0.6%. In contrast, the 0.6% RBP group had the highest level of thiobarbituric acid reactive substances (TBARS). Data from the present study provide valuable information to include RBP as an ingredient without affecting performance and egg production. It is an interesting option within the framework of the circular economy and of reusing vegetable products to use this ingredient in animal feed.
