Summary: The study evaluated the effects of dietary deoiled soy lecithin supplementation on milk production, plasma and milk fatty acid content, and apparent fatty acid digestibility in lactating dairy cows. The results showed that lecithin supplementation had an impact on dry matter intake, milk fat composition, and fatty acid profile, but did not significantly affect milk yield.

Summary: The objective of this study was to determine the effects of supplementing transition dairy cows with a low inclusion dry glycerol product in the pre-and post-partum periods. The results showed that supplementation with glycerol before calving can reduce weight loss and increase feed intake, while supplementation after calving can reduce blood glycerol and NEFA concentrations, as well as decrease milk fat content.

Summary: Previous studies have shown that a high-fat diet contributes to liver fibrosis progression, and recent research focuses on the effects of different fat sources on non-alcoholic steatohepatitis. Specifically, trans fatty acid (TFA) and cholesterol-rich diets, but not saturated fatty acid (SFA) diets, have been found to significantly contribute to hepatic fibrosis in animal models.

Summary: This study analyzed the effects of fat and protein supplementation on milk fat composition, structure, and solid fat content in dairy cattle. The results showed that fat supplementation had more significant changes on milk fat TAG composition and increased the solid fat content. These alterations may impact the absorption of fat and minerals in infant milk-based products and the processing of milk fat.

Summary: The study showed that supplementing NaHCO3, MgO, and CaMg(CO3)2 in a high-starch diet can promote milk fat output by modulating diurnal ruminal pH and ruminal volatile fatty acids profile in dairy cows. CaMg(CO3)2 has similar ability to MgO in promoting milk fat synthesis and alleviating the duration of time ruminal pH remains below 5.8.

Summary: The study indicates that a high-fat diet may increase the risk of breast cancer, especially in postmenopausal women. Individuals with high intake of animal fat and polyunsaturated fatty acids are more likely to develop BC, but there is no association in premenopausal women.

Summary: This study investigated the feasibility of using corn stover hydrolysate (CSH) as a carbon source for the production of palmitoleic acid (POA) by engineered S. cerevisiae. Although the growth of yeast was inhibited by CSH to some extent, the POA production with CSH was slightly higher than that with pure glucose. The C/N ratio of 120 and the addition of 1 g/L lysine increased the POA titer. Under optimized conditions, a high POA content of 57.5% (v/v) and a highest POA titer of 6.56 g/L were achieved.

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: During diestrus, there is an accumulation of fatty acids and oxylipins in the uterine lumen, which may serve as a mechanism to supply these lipids to the developing conceptus in late diestrus.

Summary: The leather industry pollution increases the levels of lead and arsenic in cows' blood, leading to decreased antioxidant activity and reduced linoleic acid content in milk. Heavy metal exposure through the leather industry affects the synthesis of unsaturated fatty acids in milk by inducing oxidative stress in cows.

Summary: The objective of this study was to evaluate the effects of varying the ratio of dietary palmitic and stearic acids on nutrient digestibility, production, and blood metabolites of early-lactation Holsteins under mild-to-moderate heat stress. The results showed that feeding diets rich in palmitic acid can increase the fat-corrected milk production of lactating cows and improve feed efficiency.

Summary: The study suggests that replacing soybean meal with corn dried distillers grains with solubles (cDDGS) in animal feed, along with the addition of beef tallow or coconut oil, can improve meat quality in terms of water holding capacity and fat content. Additionally, the type of dietary fat used can affect the fatty acid composition and meat quality traits.

Summary: The study demonstrated that cefminox sodium (CMNX) has a therapeutic effect on fatty accumulation in animal and cell models. CMNX reduced fatty liver in mice on a high-fat high-sugar diet and alleviated fatty accumulation in liver cells. The mechanism behind this effect involves inhibition of fatty acid synthesis and facilitation of fatty acid oxidation.

Summary: The study aimed to investigate the impact of week of lactation and experimental nutrient restriction on milk metabolites and fatty acids in early-lactation cows. The results showed that certain milk metabolites can serve as potential biomarkers for energy status in early-lactation cows, with changes observed in response to both week of lactation and nutrient restriction. Additionally, different milk components exhibited varied responses to these factors, suggesting the complexity of metabolic regulation during early lactation in dairy cows.
