Summary: A total of 60 green turtle eggs were obtained from sampling sites in Terengganu and Sabah, Malaysia. Bacteria from these eggs were isolated and identified, revealing 12 genera with 12 different species. The most frequently isolated bacteria were Salmonella and Proteus. While there were slight differences in crude protein and crude fat content between the samples from the two sites, there were no significant differences in the nutritional compositions, fatty acid contents and amino acid compositions. However, heavy metal concentrations differed significantly between the two sites.

Summary: This study investigated the effects of supplementing different levels of sunflower hulls to the complete feed of late-gestation pregnant ewes on the nutritive and fatty acids profile of colostrum. Results showed that inclusion of sunflower hulls at levels greater than 20% may have negative effects on some fatty acid parameters, while up to 20% can be used without negative effects on colostrum fat content and fatty acids profiles.

Summary: This study investigated the effect of consuming 300 mg of egg yolk choline per day on cognitive function in Japanese adults. The results showed that the intake of egg yolk choline improved verbal memory, which is a part of cognitive functions. However, more well-designed and large-scale studies are needed to confirm these effects.

Summary: This study found that adding hesperidin to quail diets can increase the weight of eggs and certain fatty acid contents, but may affect the fracture resistance of the eggshell.

Summary: This study aimed to investigate the effects of autoclave heating (AH) on the chemical composition, antioxidant properties, and functionality of undried fresh brewers' spent grain (BSG). The results showed that AH could modify the fatty acid composition, reduce the levels of certain compounds regardless of the water ratio, and improve the total flavan-3-ols content, antioxidant activities, and water-holding capacity of BSG.

Summary: Supplementing laying hens with 3% Hermetia illucens larvae meal can improve egg weight and protein quality, but may have negative effects on eggshell thickness and yolk index during the early stages of the experiment. Additionally, the supplementation enhances the antioxidant capability and immune function of the hens.

Summary: Fatty acids play a critical role in the embryonic development of cephalopods, but little is known about their allocation to eggs during oogenesis. We studied the fatty acid profiles of the ovary and eggs in the oviduct of the Argentine shortfin squid to understand how nutrients are utilized for egg production. We found significant differences in fatty acid profiles between the ovary and eggs, suggesting consistent nutrient allocation to eggs regardless of the maturity stage of the ovary.

Summary: The fatty acid composition of Japanese rock ptarmigan's yolk was analyzed and compared to commercially reared poultry species. The findings showed higher levels of polyunsaturated fatty acids in ptarmigan yolk samples compared to commercially reared poultry. The difference between commercial controls and ptarmigan was greater than the difference between different groups of ptarmigan, suggesting that genetic factors may play a role in the fatty acid profile of Japanese rock ptarmigan.

Summary: This study investigated the enrichment of egg yolks and tissues of laying hens with very long chain omega-3 fatty acids (VLCn-3 FA) using two different oils. The results showed that both oils increased the VLCn-3 FA content in egg yolks, liver, breast, thigh, and adipose tissue compared to the control group, with AHI oil having a greater enrichment effect than FLAX oil. Additionally, the enrichment efficiency of VLCn-3 FA in egg yolks decreased with higher oil levels, particularly with FLAX oil.

Summary: This study investigated the effects of including poultry byproducts compost in the diet on yolk fatty acid profile, egg sensory characteristics, and serum biochemical indices of laying hens. The results showed that adding different levels of compost to the diet did not significantly affect the yolk fatty acid composition and egg sensory characteristics, as well as serum biochemical indices. Therefore, poultry waste compost can be used up to 10% in layer rations without detrimental effects and can effectively reduce feed cost.
