Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: The fatty acid content and level in different tissues of the Baikal grayling varied significantly, with C24 PUFAs being the main components. The highest rate of DHA synthesis was observed in the brain, while the lowest was likely in adipose tissue. Some tissues contained beneficial substances for human health.

Summary: It is important to consider the breeder age when obtaining chicks for broiler fattening, as it affects the mineral levels in eggs and bones. This study aimed to examine the changes in mineral levels, embryonic development, and bone characteristics according to breeder age. The results showed that older breeders produced eggs with higher weight and embryos with greater weight and length. The mineral levels in the shell, albumen, yolk, and bones of embryos and chicks were also higher in the older breeders. This information can be useful in designing in-ovo injections, formulating diets, and preventing bone diseases in broilers.

Summary: The chicken embryo model has emerged as an alternative to rodents in immune-based studies, offering advantages such as cost-effectiveness, time efficiency, and ease of use. It can be utilized for specific experimental hypotheses or preclinical testing, potentially serving as a valuable tool in biomedical research.

Summary: The transgenerational effects of certain nutrients, such as essential fatty acids, have gained attention in human medicine and animal sciences. In this review, the focus is on how maternal dietary n-3 or n-6 fatty acids can impact the remodeling of long chain n-3 and n-6 PUFA in hatching eggs and chick tissues, and its subsequent effects on chick growth and PUFA metabolism during early life.

Summary: This study evaluated the fatty acid (FA) composition in the milk of lactating Tibetan women and the consequences of dietary patterns. The milk was found to have high levels of total saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) compared to milk from other regions in China. However, total polyunsaturated fatty acids (PUFA) were slightly lower, and the concentration of docosahexaenoic acid (DHA) was significantly lower. The main n-3 FAs in human milk, including DHA and EPA, may be influenced by carbohydrate intake.

Summary: This study found that different ratios of EPA and DHA have different impacts on adipose tissue metabolism, with fish oil rich in EPA instead of DHA effectively reversing changes induced by obesity.

Summary: The study evaluated the embryo-toxicity of omega-3 fatty acids using in silico predictions and a chick embryo model. Results showed that DHA and EPA could lead to adverse effects on embryonic tissues and vessel apoptosis, indicating an essential pathway in the embryo-toxicity of omega-3.

Summary: This study aimed to determine whether the partial replacement of soybean meal (SBM) with defatted Hermetia illucens larvae meal (HIM) in the diet of laying hens is possible without negative impacts on performance indices, egg quality, and health. The results showed that the inclusion of HIM at any level in the diet did not affect the laying performance parameters of the hens. However, it did have notable effects on the cholesterol level and fatty acid profile in the egg yolks.

Summary: Reducing the expression of the LPC-DHA transporter MFSD2a specifically in the placenta resulted in reduced fetal brain weight and lower phospholipid DHA content in the fetal brain. These findings provide mechanistic evidence of the critical role of placental MFSD2a in maternal-fetal transfer of LPC-DHA for brain growth.

Summary: A recent study on chick retinas found that fatty acid binding proteins (FABPs) are highly expressed and play a role in regulating the function of glial cells and microglia. Inhibition of FABPs leads to transitions of glial cells to reactive states and suppresses the formation of progenitor cells, while inhibition of fatty acid synthase (FASN) increases microglia proliferation and suppresses progenitor cell formation.

Summary: A marine ecosystem survey conducted in September 2016 in the Arctic Ocean to the west and north of Svalbard showed that recent environmental changes have affected the diets and body condition of harp seals, with body condition slightly lower for older seals in 2016 compared to earlier samples. Polar cod and the pelagic hyperiid amphipod Themisto libellula continue to dominate the seal diet, with the absence of bottom associated species and the presence of alternative species such as Atlantic cod and blue whiting due to changes in ice edge localization.
