Commercial high-yielding corn hybrids have not been evaluated for their ability to pigment egg yolk. Therefore, the objective of this research was to investigate the effects of commercial hybrids with different carotenoid profiles as the only source of pigments in the diets of hens on yolk color and carotenoid content, as well as the carotenoid deposition efficiency into the yolk. Treatment diets, differing only in one of five corn hybrids, were offered in a completely randomized design in six cages per treatment, each with three hens. Treatment diets and yolks differed in carotenoid profile (contents of lutein, zeaxanthin, β-cryptoxanthin and β-carotene, p < 0.001), with total carotenoid contents ranging from 17.13–13.45 µg/g in diet and 25.99–21.97 µg/g in yolk. The treatments differed (p < 0.001) in yolk color, which was determined by yolk color fan (10.8–9.83) and CIE Lab (redness; range 12.47–10.05). The highest yolk color intensity was achieved by a diet with the highest content of zeaxanthin, β-cryptoxanthin and β-carotene. The deposition efficiency of lutein and zeaxanthin (25.52 and 26.05%, respectively) was higher than that of β-cryptoxanthin and β-carotene (8.30 and 5.65%, respectively), and the deposition efficiency of all carotenoids decreased with increasing dietary content. Commercial corn hybrids provided adequate yolk color and could be the only source of carotenoids in the diets of hens, which could reduce the cost of egg production and increase farmers’ income.

The aim of this study was to evaluate the effect of a supplementation diet for hens consisting of dried basil herb and flowers of calendula and dandelion for color, carotenoid content, iron-induced oxidative stability, and sensory properties of egg yolk compared with commercial pigment (control) and marigold flower. The plant parts were supplemented in diets at two levels: 1% and 3%. In response to dietary content, yolks from all diets differed in carotenoid profile (p < 0.001). The 3% supplementation level resulted in a similar total carotenoid content as the control (21.25 vs. 21.79 μg/g), but by 3-fold lower compared to the 3% marigold (66.95 μg/g). The tested plants did not achieve yolk color fan values as the control (13.47) or 3% marigold (11.47), and among them, calendula had the highest values (9.73). Despite the low carotenoid content in diets supplemented with basil herb, iron-induced malondialdehyde (MDA) concentration was low as for marigold (on average 106.83 vs. 92.68 ng/g after 250 min). The treatments differed in sensory color scores for fresh and hard-boiled yolks and flavor while other sensory properties were similar. In conclusion, the supplementation of plants in a hen diet may result in yolks containing carotenoids and other compounds showing a high antioxidant effect.

 The environment is very important for the performance of laying hens; thus, techniques are required to improve production systems, providing better welfare for poultry and consequent increase in the quality of the final product, the egg. This study aimed to evaluate the effects of rearing system, on the floor and in cage, on the performance and egg internal and external quality of laying hens. A total of 320 Hysex Brown laying hens, with 34-43 weeks days of age, was distributed in a completely randomized design, with two treatments, floor and cage, with 10 replicates each. The parameters evaluated were: individual feed intake, egg production per replicate, feed conversion per dozen eggs, egg weight; weight and percentage participation of shell, albumen and yolk, specific gravity, body weight variation and viability of birds. The results show that the birds raised on the floor showed best results as to egg production, besides the best internal and external quality, with greater weight of egg, yolk, albumen, shell and with lower losses of eggs. Because of the negative effects of the cage system, in general, hens presented lower results when compared to results of those raised on the floor.

This study aims to produce Pegagan duck eggs which is high in antioxidants to be used as functional comestibles. Efforts to achieve these goals can be done by adding a source of natural antioxidants in the form of legume leaves of Indigofera zollingeriana which contain active compounds of β-carotene. The study used a completely randomized design (CRD) consisting of 5 treatments (4 replications each), which were levels of Indigofera zollingeriana top leaf meal supplementation (R0 = 0%, R2 = 1%, R2 = 2%, R3 = 3% and R4 = 4%) in Pegagan duck rations. The observed variables are production performance; egg quality, both physically and chemically. Physical quality includes egg weight, eggshell percentage, egg white weight percentage (albumen), and weight percentage of egg yolk and egg yolk color. The quality of egg chemistry includes the content of vitamin A, β-carotene, cholesterol, and antioxidant activity of eggs. The data obtained were analyzed by variance analysis, followed by the Duncan Multiple Range Test. The results showed that supplementation of Indigofera zollingeriana top leaf meal in rations could improve egg quality and contain antioxidants. Supplementation of Indigofera zollingeriana top leaf meal with a dose of 4% in rations can increase the color of the yolk by 43.40%, reduce the inhibition rate by 11.38%, with an increase in the content of β-carotene by 75.23% and can maintain normal cholesterol in eggs.

Background and Aim: Green food is the natural diet for livestock and poultry. Therefore, production of green food in sufficient quantities to meet the current demand has emerged as an urgent problem today. The use of natural laylands results in green food shortage, which, in turn, necessitates the application of various methods of artificial production of green herbage. One of these methods is hydroponic cultivation of green grass as animal feed. Hence, this study was conducted to investigate the productive and reproductive qualities of geese of the parent herd. Materials and Methods: Complex scientific analysis was conducted to explore the effect of hydroponic green herbage used at various dosages (20%, 25%, 30%, and 35% of total diet weight) on the realization of the reproductive qualities of parent flock geese. The methodological framework of this research is the efforts of various foreign and domestic scientists on the topic under study. This research was conducted using generally accepted methods (i.e., experiment, comparison, analysis, and generalization), along with special methods (zootechnical, physiological, biological, hematological, morphological, statistical, and economic). Results: The optimal dosage of hydroponic green herbage for geese diet was established, which constituted 25-30% of the total diet weight and increased the poultry population survival rate by 2.0%, egg production rate by 3.8%, and the hatching egg yield by 4.9%. The carotenoid content in egg yolk ranged from 1.62 to 3.50 μg. The content of Vitamins A and B2 was higher by 3.19 and 2.32 μg, respectively, compared to that in the control. The production profitability level increased by 9.6%. Conclusion: By introducing 25-30% of hydroponic greens from the weight of the diet, it is possible to increase the safety of livestock by 2%, the yield of hatching eggs by 4.9%, egg production by 1.46-1.11 μg.

This study evaluated the effect of pequi peel meal in the diet for laying hens on performance and egg quality. Hy-Line® Brown hens (n=160) aged 55 weeks with 1642±63g body weight were distributed in a completely randomized design with five treatments and four replications of eight birds each. The treatments consisted of isometric substitution of corn by pequi peel meal at 0, 2.5, 5.0, 7.5 and 10%. The performance and internal and external egg quality were evaluated. Egg production, egg mass and feed conversion worsened linearly with increasing replacement of corn with pequi peel meal, while the yolk color increased linearly. The other variables related to performance and internal and external egg quality were not significantly affected by the treatments. It can be concluded that the use of pequi peel meal replacing corn in laying hen diet does not change the internal and external egg quality, improves the pigmentation of egg yolk, and impairs performance of laying hens.

We evaluated the carotenoid profile and concentration (by HPLC) and the phytochemical content of two OFSP varieties (Umuspo 3 and Ex-Igbariam) planted at three distances (20 cm, 30 cm and 40 cm) and harvested in two different periods (12thand 16thweeks after planting) respectively. Carotene contents of the outer peel and inner flesh of the sweet potato varieties were also determined. The results showed wide variation in the carotenoid and phytochemical content among the varieties at different planting spaces and harvest periods. Umuspo 3 planted at 20 cm, 30 cm and 40 cm had significantly greater carotenoid concentration than Ex-Igbariam variety. The predominant carotenoid was β-carotene with highest concentration obtained from 40 cm planting distance (92.82µg/g) and 30 cm (80.97µg/g) for Umuspo 3. Ex-Igbariam at 30 cm planting distance contained 2.51µg/g β-carotene when harvested after 16thweeks. Also the highest β-carotene concentration was from Umuspo 3 flesh sample planted 30 and 40 cm (409.45 and 441.15 mg/100g) and the peel for samples planted 30 and 40 cm (490.47 and 640.69 mg/100g, respectively) at the 12thweek of harvest. Flavonoids were present in significant amounts (310.62mg/100g) in Umuspo 3 planted at 30 cm and harvested after 12thweek while in total polyphenol, significant quantities of ≈42.12mg/100g was present in Ex-Igbariam spaced at 30 cm and 40 cm and harvested after 16thweek. Provitamin A carotenoid was calculated and Umuspo 3 pro-vitamin A carotenoid was significantly higher (p< 0.05) with highest concentration (742.26 RE/100g) present in samples from 40 cm planting distance. The results showed that planting space and harvesting period had significant impact on the carotenoid and phytochemical concentrations of OFSP varieties. Planting distances of 30 and 40 cm are recommended for high carotenoid content in the two sweet potato varieties.

Eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and carotenoids are needed as human dietary supplements and are essential components in commercial feeds for the production of aquacultured seafood. Microorganisms such as thraustochytrids are potential natural sources of these compounds. This research reports on the lipid and carotenoid production capacity of thraustochytrids that were isolated from coastal waters of Antarctica. Of the 22 isolates, 21 produced lipids containing EPA+DHA, and the amount of these fatty acids exceeded 20% of the total fatty acids in 12 isolates. Ten isolates were shown to produce carotenoids (27.4–63.9 μg/g dry biomass). The isolate RT2316-16, identified as Thraustochytrium sp., was the best producer of biomass (7.2 g/L in five days) rich in carotenoids (63.9 μg/g) and, therefore, became the focus of this investigation. The main carotenoids in RT2316-16 were β-carotene and canthaxanthin. The content of EPA+DHA in the total lipids (34 ± 3% w/w in dry biomass) depended on the stage of growth of RT2316-16. Lipid and carotenoid content of the biomass and its concentration could be enhanced by modifying the composition of the culture medium. The estimated genome size of RT2316-16 was 44 Mb. Of the 5656 genes predicted from the genome, 4559 were annotated. These included genes of most of the enzymes in the elongation and desaturation pathway of synthesis of ω-3 polyunsaturated fatty acids. Carotenoid precursors in RT2316-16 were synthesized through the mevalonate pathway. A β-carotene synthase gene, with a different domain organization compared to the gene in other thraustochytrids, explained the carotenoid profile of RT2316-16.

Β Carotene

Carotenoids are essential in the human diet for their important functions in health. Besides, they are responsible for the yellow pigments desirable for industrial quality in durum wheat. The remarkable carotenoid content of durum wheat endosperm is mostly due to lutein. However, lutein esters have not been previously detected in durum wheat as in other cereals such as common wheat, tritordeum or Hordeum chilense. Esterification increases carotenoid stability and allows greater retention and accumulation through the food chain. Therefore, carotenoid esterification is revealed as a new key target in breeding. We characterized the carotenoid profile of 156 accessions of the Spanish durum wheat collection, searching for landraces with esterification ability. Interestingly, four accessions produced lutein monoesters and diesters. Also, traces of lutein monoesters were detected in eleven accessions. The identification of the first durum wheat accessions with esterification ability reported herein is a remarkable advance for carotenoid biofortification. Furthermore, variation for the relative content of zeaxanthin, α-carotene and β-carotene was also observed. This diversity for the β,ε and β,β branches of the carotenogenic pathway also represents a new opportunity for breeding for specific carotenoids in biofortification programs.

The efficiency of introducing probiotics based on strains of Bacillus subtilis, Bacillus licheniformis and their consortium in the amount of 150 g/t of feed into the diets of laying quails has been studied. The experiment lasting 182 days has been carried out on four groups of quails with 30 heads in each. The quails have been housed in the broiler battery in compliance with the required microclimate conditions. Quails of all groups have been received the main diet (compound feed) developed taking into account their age and physiological characteristics. The quails of the 1st, 2nd and 3rd experimental groups in addition to the main diet received probiotics (150 g/t compound feed) based on strains Bacillus subtilis, Bacillus licheniformis and their consortium, respectively. It has been found that feeding the laying quails of the consortium of strains Bacillus subtilis and Bacillus licheniformis had the most significant positive impact on their productive performance, it allowed to increase egg production by 7,81 %, egg laying intensity by 5,0 %, egg mass yield by 9,77 %, while reducing feed expenditures for 10 eggs by 13,35 %. The yield of hatching eggs has been increased by 7,03 %, hatchability of chickens from laid and fertilized eggs by 8,33 and 8,35 %, brooding waste decreased by 21,74 %. Hematological parameters of quails during the whole experiment were within the physiological norm. The economic effect calculated on the basis of data on the cost of compound feed, probiotics and the cost of sold eggs of quail laying was 14,56 % in the 3rd experimental group (in relation to the control group).
