“…Improvements in egg yolk color when the diets of hens were supplemented with rosehip meal were previously reported by Vlaicu et al [ 6 ] and were attributed to the high content of carotenoid pigments in rosehips. Many consumers prefer eggs with a more intensely pigmented yolk because they associate the intense color with high contents of nutrients, especially xanthophylls and lutein, which play a role in the prevention of certain eye diseases [ 51 ].…”

The present study was conducted to investigate the effects of introducing hemp seeds, as a source of PUFAs, into a standard diet with or without dried fruit pomace (dried blackcurrant (DB) or dried rosehip (DR)), as a source of natural antioxidants, on the laying performance of hens and the FA profile, cholesterol level, antioxidant content, and lipid oxidative status in the yolks of fresh eggs or eggs stored at 4 °C for 28 days. The experiment used 128 Tetra SL hens at 35 weeks of age, which were divided into four groups and randomly assigned to four dietary treatments: a standard corn–wheat–soybean meal diet (C), standard diet containing 8% ground hemp seed (H), hemp seed diet containing 3% dried blackcurrant pomace (HB), and hemp seed diet containing 3% dried rosehip pomace (HR). The laying rate, feed conversion ratio (FCR), egg weight, and yolk weight were improved by the use of hemp seeds. The yolks of the H, HB, and HR eggs had a lower cholesterol (p ˂ 0.01) and SFA content, while the concentration of total and individual PUFAs (n-6 and n-3 FAs) was significantly higher (p ˂ 0.01) compared to C. In addition, the introduction of hemp seeds into the diets alone or with dried fruit pomace (DB or DR) led to increased (p ˂ 0.001) content of α-linolenic acid (ALA, 18:3n-3), eicosapentaenoic acid (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3) and hypo-/hypercholesterolemic FA ratio and decreased arachidonic acid (AA, 20:4n-6) content, n-6/n-3 ratio, and thrombogenicity index (TI) compared to the control eggs. The introduction of dried fruit pomace (DB or DR) into the diets had no effect on the laying performance of the hens or the cholesterol content and FA profile of the egg yolks, compared to the diet supplemented only with hemp seeds. The dried fruit pomace improved the color, accumulation of antioxidants, and oxidative stability of fats in the yolks of the fresh eggs and eggs stored at 4 °C for 28 days. The DR was found to have the most desirable effects, producing the most intense color of egg yolks, the highest content of natural antioxidants, and the best oxidative stability of yolk lipids.

Hemp seed meals contain high protein and unsaturated fatty acids which have the potential as a substitute for soybean meal and yield eggs rich in unsaturated fatty acids. Therefore, the study aimed to evaluate the impact of dietary hemp seed meal as a substitute for soybean meal protein on productive performances, egg quality, and yolk fatty acid composition. A total of 120 Lohmann Brown laying hens aged 50 weeks were separated into 4 groups and 10 repetitions with 3 birds each. Birds received treatment without hemp seed meal (control group), or soybean meal substituted with 4%, 8%, and 12% hemp seed meal. Dietary 4% hemp seed meal significantly increased (p < 0.05) feed efficiency and egg production compared to the 8% and 12% hemp seed meal group. Meanwhile, feed intake, egg weight, body weight loss, egg shape index, albumen index, albumen weight, Haugh unit, yolk weight, yolk index, and eggshell thickness had no significant influence (p > 0.05). However, dietary 8% and 12% hemp seed meal significantly increased (p < 0.05) eggshell weight and yolk color score compared to the control and 4% hemp seed meal group. There was a significant increase (p < 0.05) in omega-3 fatty acid levels and a significant decrease in yolk omega-6 to omega-3 fatty acids ratio with an increase in dietary hemp seed meal. It concluded that dietary 4% hemp seed meal as soybean meal substitution was able to increase egg production, and feed efficiency compared to the level of 8% and 12% hemp seed meal. Increasing dietary levels of hemp seed meal increased eggshell weight, yolk color, and omega-3 fatty acids content, and decreased the omega-6 to omega-3 fatty acids ratio.
