“…Linseed oil inclusion to layer diet at 2.5% reported to increase the egg yolk PUFA content with no significant change in egg yolk cholesterol content (Batkowska et al, 2021). Furthermore, Duan et al (2021) suggested that LO inclusion by 2% can be beneficial for the production of functional eggs enriched with docosahexaenoic and α-linoleic acids. However, the optimum amount of LO addition to layer diet for the best egg production with high PUFA content and low cholesterol egg content still unknown.…”

Chicken eggs are considered one of the most common high nutritive value animal protein foods sources consumed all over the world. Recently, with the increasing of health-conscious there is a growing interest in producing and consuming functional foods especially for individuals suffering from chronic diseases. The current study aimed to investigate the effect of dietary linseed oil (LO) inclusion, as enriched-source of omega-3 polyunsaturated fatty acids, on egg production performance and egg yolk cholesterol content, blood hematology and biochemical composition of commercial laying hens. A total of 180 Hy-Line brown laying hens 36-week-old were randomly divided into four groups (9 replicates x 5 birds each). The four groups were fed a basal diet formulated to contain; 0, 2, 4 or 6% LO for six weeks. Results showed a significant improvement in egg production performance with dietary LO inclusion ranged from 3 to 4%. Data revealed a significant reduction in egg yolk cholesterol content by 15, 17 and 21% for the 2, 4 and 6% LO groups, respectively, compared to the 0% LO group. Meanwhile, blood high-density lipoprotein was significantly increased, while the low-and very-low-density lipoprotein cholesterols were significantly decreased by LO treatment, compared to the 0% LO group. Dietary LO did not show any adverse effects on the measured blood hematological or plasma biochemical parameters of the layers. It can be concluded that inclusion of LO into layer's diets can be safely used to enhance egg production. Furthermore, LO inclusion might have a beneficial impact on reducing egg cholesterol content which can be considered as an adding value for consumer's general health. The economic efficiency evaluation reviled that diet fortified by 6% LO is the most efficient diet in respect of the current Saudi Arabia market's prices.

“…Previous studies have found that perilla seed extract (PSE) lowers blood lipids in mice and breeder hens and affects egg quality and fatty acid composition [23][24][25]. PS consumption by the hens could also influence the unsaturated fatty acid content of the eggs and thus improve their nutrition [26,27].…”

The aim of this study was to investigate the effects of adding perilla seed meal (PSM) to the diet on reproductive performance, egg quality, yolk fatty acids, antioxidant capacity and liver lipid metabolism in breeding hens. A total of 192 31-week-old yellow-feathered hens were randomly divided into 4 treatments with 6 replicates of 8 birds for 8 weeks. The chickens were fed a typical corn–soybean meal diet containing 0% (control), 0.3%, 0.6%, and 1% PSM. The results showed that PSM can change the productivity of laying hens. Adding 0.6% PSM to the feed reduced the mortality rate of chickens. Adding 1% PSM improved the fertilization rate and hatching rate of chickens. Regarding egg quality, the albumen height and Haugh unit were improved in the 0.6% PSM group. The content of MUFAs and PUFAs in the egg yolk was increased in all the PSM groups, while SFAs were only increased in the 0.6% PSM group. Among the indicators related to lipid metabolism, serum GLU decreased in all the PSM groups. The 0.6% PSM group had a reduction in serum and liver TG, as well as reductions in serum LDL-C and ALT. The same results were observed for the abdominal fat percentage in the 0.6% PSM group. Liver lipid metabolism-associated gene expression of FAS and LXRα was decreased in all the PSM groups, and the mRNA expression of ACC and SREBP-1c was significantly reduced in the 0.6% PSM group. HE staining showed that the vacuoles in the liver tissue gradually decreased with increasing PSM doses, especially the 1% PSM dose. Lipid droplets with a similar trend were observed using Oil Red O staining. In the results of the antioxidant capacity test, the serum T-AOC was increased in the 0.6% and 1% PSM groups, and the SOD in both the serum and liver was significantly increased in all the PSM groups. The expression of antioxidant-related genes such as Nrf2, NQO-1, HO-1, CAT and GSH-Px was significantly upregulated in the 1% PSM group. In conclusion, the PSM diet improved the lipid metabolism and antioxidant capacity of breeding hens. PSM reduces mortality and improves fertilization and hatchability in the late laying period of chickens, resulting in greater benefits. We recommend adding 0.6% PSM to layer feed, which improves the physical condition of the hens and brings higher economic benefits.
