Summary: This study evaluated short-term variations of trans fatty acids (TFA) in plasma lipoproteins and ruminal fermentation parameters of non-lactating cows subjected to ruminal pulses of vegetable oils. Results showed an accumulation of several C18:1 TFA in plasma and lipoproteins, especially on the third day of pulsing. Different C18:1 TFA responded differently to treatments over time.

Summary: The study shows that PUFA in SBO combined with CT are effective in modulating ruminal BH and CH4 production, but high doses of added CT can reduce ruminal VFA concentration. A level of 0.4% GSTE added to diets containing 2.5% PUFA from plant origin may optimize ruminal fermentation and BH of C18:2 c9,c12 to fatty acid intermediates. Adding 0.4% grape seed tannin extract with 2.5% soybean oil is suitable for improving in vitro ruminal fermentation and BH.

Summary: Inclusion of dietary vegetable sources rich in UFA in sheep diets helps improve cheese composition by decreasing saturated FA content and increasing polyunsaturated FA content. However, the effects on milk yield, milk fat percentage, and milk protein percentage are not significant, with significant heterogeneity present.

Summary: Extracts of Cistus ladanifer condensed tannins showed moderate effects on rumen fermentation, with a decrease in volatile fatty acids production and microbial fatty acids. However, the biohydrogenation process was minimally affected, suggesting a possible adaptative response of the microbial population to the stress induced by the tannins.

Summary: Conjugated linoleic acid (CLA) has protective effects against various diseases and can improve human health. The levels of CLA in milk can be increased through grazing feeding, which provides higher amounts of CLA precursors compared to balanced diets. Agronomic practices, such as nitrogen fertilization and regrowth age, can also increase the content of CLA precursors in pastures. This technique of increasing CLA levels in milk adds nutritional value to the milk.

Summary: Supplementation of betaine in the diet improved zootechnical performance, decreased abdominal fat and sebum thickness in geese at 63 days of age, and reduced triglyceride and total cholesterol content in serum. Betaine also increased hormone sensitive lipase activity while decreasing fatty acid synthase activity in geese, leading to reduced lipid droplet area. Further research is needed to fully understand the mechanisms behind these effects.

Summary: Microbial digestion is crucial for ruminants, and disruptions can impact product quality and efficiency for human consumption. The conversion of unsaturated fatty acids in the rumen can result in a variety of fatty acids. Certain dietary conditions can lead to a shift towards trans-10 fatty acids instead of the usual trans-11 fatty acids, which causes milk fat depression in dairy cows.

Summary: The study compared the effects of tannins from different sources on the fatty acid composition in sheep's ruminal fluid. The results showed that both sampling time and animal diet had a significant impact on the tested parameters. The addition of tannic acid had a greater influence on the fatty acid profile in the rumen compared to oak bark extract. The increased concentrations of certain fatty acids suggested that tannic acid may inhibit the initial stage of fatty acid biohydrogenation.

Summary: The study investigated the correlation between rumen bacterial community composition and rumen lipid metabolism in 40 beef steers. The results showed that certain bacterial genera had significant impacts on the presence of specific fatty acids. The relationship between genera and fatty acids varied according to the breed, indicating the influence of host genetic background. These findings provide insights into the activity of the rumen population in lipid metabolism.

Summary: This study found that dietary intake of C18:2n-6 can improve populations of fibrolytic bacteria and rumen fermentation indices, while a mixture of pure C18:2n-6 and C18:3n-3 is recommended for effectively reducing enteric methane emissions and resisting biohydrogenation in the rumen with less impact on rumen microbes.

Summary: The intermittent application of a FMD, with low carbohydrate/protein content and high dietary fiber, can reduce obesity and glucose intolerance induced by a high-fat high-sucrose diet in mice. It also decreases adipocyte size, increases expression of lipolysis genes and HSL protein in white adipose tissue, and reduces HFHSD-induced lipid accumulation in the liver. RNA sequencing shows elevated expression of genes involved in fatty acid oxidation with FMD intervention.

Summary: Livestock, particularly ruminant animals like cows, sheep, and goats, contribute significantly to greenhouse gas emissions, primarily through methane production. This study explores the potential of sage, pine, and clove essential oils as natural additives to manipulate ruminal fermentation and the biohydrogenation of polyunsaturated fatty acids. The essential oils were found to reduce gas and methane production, affect rumen pH, ammonia levels, and fatty acid profiles. Overall, this research suggests that these essential oils have the potential to reduce methane emissions and improve the quality of livestock products.

Summary: Human CES2 plays a crucial role in protecting and reversing steatohepatitis by inducing lipolysis and fatty acid oxidation, inhibiting lipogenesis, and improving mitochondrial function. Targeting hepatic CES2 may be a promising strategy for treating NAFLD.

Summary: This study uses economic analysis to estimate the impact of feeding dietary supplements on milk production in dairy cows experiencing heat stress, and compares the results with actual animal experiment. The pre-experimental economic analysis suggests that feeding betaine, fat, or betaine plus fat would require increased milk production to be equally profitable as the control diet. The post-experimental results show that supplementing diets with fat or betaine alone can exceed the milk production threshold, while feeding both does not result in the expected extra milk production.

Summary: Supplementing the diet of lactating cows with ingredients that increase energy density or reduce internal heat production can mitigate the negative impacts of hot weather on milk yield. While fat supplementation improved milk production, it also increased body temperature, while betaine supplementation reduced body temperature but did not affect milk yield. Surprisingly, the combination of fat and betaine did not show clear benefits in terms of milk production or body temperature, indicating a need for further research on their interaction during hot weather conditions.
