Summary: This study measured the size distribution of bovine colostrum fat globules (CFG) and analyzed its relationships with postpartum milkings, parity, and fatty acids profile. The results showed that CFG size almost doubled during the postpartum milkings, while lactation had little effect on CFG size. The fatty acids profile analysis also revealed significant differences between the fourth postpartum milking and the previous milking. Based on these findings, the first three postpartum milkings can be considered as colostrum, while the fourth milking represents transition milk.

Summary: This study investigated the effects of milking frequency, breed, and stage of lactation on the size of milk fat globules (MFG) and the composition of fatty acids (FA) in sheep milk. It was found that milking frequency had no impact on MFG size, but lactation stage had a significant effect. FA composition also varied according to lactation stage and breed.

Summary: This study investigated the effects of fat supplements containing different levels of palmitic acid (PA) and stearic acid (SA) on milk production and nutrient metabolism in lactating dairy cows. Supplementing PA increased milk fat yield, while a blend of PA and SA increased energy-corrected milk without decreasing intake. The fatty acid profile of fat supplements can influence their digestibility and effects on milk synthesis.

Summary: This study evaluated the influence of adherence to the healthy food pyramid, dietary pattern in the Mediterranean region, and maternal body composition on breast milk fatty acid pattern in lactating women. The study found that olive oil consumption was negatively associated with palmitic acid levels in breast milk, while intake of cereals and legumes was positively associated with saturated fatty acids. Intake of proteins and vegetables was positively associated with omega-3 fatty acids and negatively with the omega-6:omega-3 ratio in breast milk. Maternal age and physical activity also had an impact on breast milk fatty acid pattern.

Summary: The study aimed to investigate the profile of MFGM proteins during MFD induced by CLA. The results provide evidence for an important role of MFGM proteins in regulating MFG diameter, and they facilitate a mechanistic understanding of diet-induced MFD.

Summary: This study used a lipidomics approach to investigate the differences in lipidome and fatty acid composition among human, bovine, and caprine milk fat globule membrane (MFGM). The results revealed variations in lipid classes and fatty acids between different types of MFGM, providing valuable insights for the design of new infant formula.

Summary: The digestibility and content of 16C and 22C fatty acids in milk fat are influenced by different treatments, with 1-carbon donors having no effect on the digestibility of 22C fatty acids. The content and yield of 16:0 and 22:6 in milk fat show significant differences between different treatments.

Summary: The study compared the effects of dietary lipid supplements with different fatty acid compositions on milk performance in early lactation dairy goats fed a high-concentrate diet. The results showed that PALM and FLAX supplementation increased milk fat concentration, with PALM also leading to a slight increase in milk fat yield. The impact of these changes on the nutritive value of dairy products requires further investigation.

Summary: Differences in lipid droplets between infant formula and human milk can affect fat digestion and metabolism in infants. There is growing interest in simulating human milk fat, particularly in terms of fatty acids and triacylglycerols. Attention should also be given to the impact of fat modification on milk fat globules in next-generation infant formula.

Summary: The association between dietary fat and fat quality and puberty timing is inconsistent. This study found that children with higher intakes of total fat and polyunsaturated fatty acid (PUFA) were more likely to reach puberty at an earlier age, while intakes of saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) were not independently associated with puberty development.

Summary: The study showed that moderate pulsed electric field treatment can modify the structure of milk fat globules, leading to changes in milk stability, lipolysis, and fatty acid composition. Different sizes of milk fat globules have varying responses to PEF, which is significant for the development of new products and ingredients containing milk fat.

Summary: Obesity is associated with disruptions in adaptive immune system. This study investigates the effects of dietary fatty acids on T-cell maintenance in bone marrow. The findings reveal a critical role of dietary fatty acids in the selective acquisition of T-cell subsets, particularly the maintenance of CD4(+) T cells by oleic acid.

Summary: Summer grazing has a positive effect on the quality of milk fatty acids, with an increase in concentrations of long-chain fatty acids and polyunsaturated fatty acids, while concentrations of short- and medium-chain fatty acids decrease.

Summary: This article reviews studies on the composition of human milk fat globule (MFG) components over the course of lactation. It discusses the changes in concentrations of phospholipids, gangliosides, cholesterol, fatty acids and proteins and their potential implications for infant health. The article also highlights factors such as maternal diet and geographical location that can influence MFG composition.

Summary: It was found in the study that the supplementation of gilts with n-3 and n-6 enriched diets had significant effects on serum composition, fatty acid levels, and offspring weight compared to the control group. Offspring from gilts supplemented with n-3 had higher body weight, increased daily weight gain, and higher serum EPA levels. These results demonstrate the beneficial effects of PUFA-enriched cow's milk supplementation for the offspring of gilts.
