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: The direct binding of rumenic acid to cardiac myosin-2 motor domain affects the release rate of orthophosphate and the Ca2+ responsiveness of cardiac muscle. Rumenic acid can increase myocardial metabolic load and inhibit force generation in trabeculae without affecting the number of force-generating motors. Molecular docking studies show how rumenic acid binding site and associated pathways can differ among isoforms of myosin-2.

Summary: Studies have shown the potential benefits of consuming conjugated linoleic acid (CLA) and ruminant trans fatty acids (R-TFAs) in reducing the risk factors of metabolic syndrome (MetS). Encapsulation of CLA and R-TFAs can improve their oral delivery and further decrease the risk factors of MetS.

Summary: This study isolated probiotic strains from raw cow milk of the Lahaul valley capable of producing cis-9, trans-11 CLA isomer, and exhibiting antioxidant and food formulation abilities. Genome sequencing revealed the presence of antibiotic-resistance and virulence genes in Enterococcus faecalis LJM:05. The strain Latilactobacillus curvatus LGM:16 was used to develop curdled milk with superior probiotic features, antioxidant activity, and CLA-producing ability.

Summary: Conjugated linoleic acid (CLA) supplementation in lightly exercising horses may result in mitochondrial adaptations and protection against myofiber perturbation in skeletal muscle. Significant differences were observed in mitochondrial enzyme activities and antioxidant status between horses supplemented with soybean oil and CLA. Superoxide dismutase activity tended to increase over time in the soybean oil group, while glutathione peroxidase activity tended to be higher in the soybean oil group compared to the CLA group at week 12.

Summary: Essential fatty acid deficiency is common in Cystic Fibrosis (CF) patients, but pancreatic supplementation does not solve the issue, suggesting a different underlying pathology. Although the pathological mechanisms are largely unknown, CF animal models have been developed to study the molecular mechanisms associated with CF, including the relationship between CFTR and essential fatty acids. Further research is needed to fully understand the essential fatty acid status in these animal models and to identify the best model for developing therapeutics.

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 found a positive association between industrial TFAs intake and an increased risk of colon cancer, especially in individuals over 50 years old. In contrast, ruminant TFAs intake does not appear to be associated with CRC. Awareness and regulatory actions regarding hydrogenated oils are needed due to their high consumption in both developed and less developed countries.

Summary: This article discusses the role of conjugated linoleic acid (CLA) in ruminant dairy products and its regulatory mechanism on milk fat synthesis. CLA has multiple benefits, including anticancer, anti-inflammatory, immune regulation, and lipid metabolism regulation, and it has a positive impact on infant growth and health. The isomer cis-9, trans-11 CLA helps to increase milk fat content, while trans-10, cis-12 CLA inhibits it. CLA is also an important factor in determining the quality of ruminant dairy products.

Summary: The present study aimed to assess the counts, viability, and functionality of circulating and endometrial polymorphonuclear leukocytes (PMN) isolated from clinically and metabolically healthy multiparous dairy cows in the peripartum period. The findings showed that endometrial PMN in the healthy postpartum uterus are highly dynamic compared to their circulating counterparts in terms of counts, viability, and functionality.

Summary: To meet the 1.5 degrees C target, strategies to reduce methane emissions from ruminants must be implemented, including decreasing CH4 per unit meat or milk and decreasing absolute CH4 emissions. The adoption of the most effective strategies could achieve the goal by 2030, but not by 2050.

Summary: An isotope dilution model is constructed to partition the uptake of phenylalanine and tyrosine by the liver of lactating dairy cows. The model allows calculation of uptake rate, hydroxylation, synthesis, and degradation of protein. Measurement of plasma flow rate and amino acid concentrations, along with isotopic enrichments, are required for model solution.

Summary: This study aimed to predict nitrogen excretion in feces and urine of lactating dairy cows by collecting data from different continents. The study found that simple models based on dry matter intake or nitrogen intake performed well in predicting fecal nitrogen excretion, while simple models based on milk urea nitrogen and nitrogen intake performed better in predicting urinary nitrogen excretion. In the absence of intake data, complex equations using easily measured variables can be used to predict fecal, urinary, or total manure nitrogen excretion, but these equations have lower performance.

Summary: This study aimed to compare the effects of static and oscillating dietary protein feeds on nitrogen use efficiency and milk production performance in lactating dairy cows. The results showed that oscillating feeds increased urinary nitrogen excretion in lactating dairy cows, but had no significant effect on milk production performance or nitrogen use efficiency.

Summary: This study developed empirical models to predict enteric methane emissions from sheep using a global database. The models showed that including variables such as body weight and organic matter digestibility improved prediction accuracy. Age-specific equations were also found to enhance prediction performance. The study concluded that predicting sheep methane production requires considering variables such as dry matter intake, body weight, and rumen propionate proportion, and appropriate universal equations can be used across different diets and climatic conditions.

Summary: This study aimed to explain the variability in the mitigating effect of 3-NOP and investigate the interaction between diet composition and 3-NOP dose using meta-analytical approaches. The results showed that models including only the 3-NOP dose had a significant reduction effect on methane production, yield, and intensity. However, the reduction efficiency was lower for diets with higher neutral detergent fiber content. Updating meta-analyses with new data improved model performance.

Summary: This study used blood metabolic data to cluster lactating cows into imbalanced and balanced metabolic states. Predictive models based on milk composition were developed to determine the metabolic status of cows during early lactation. The combination of specific parameters improved the predictive performance of the models.

Summary: This study aimed to investigate the effects of dietary linseed oil (LSO) supplementation and DGAT1 K232A (DGAT1) polymorphism on the composition and crystallization of bovine milk fat. The results showed that LSO supplementation increased unsaturated triacylglycerols and reduced saturated triacylglycerols in the milk fat. The DGAT1 KK genotype was associated with higher levels of odd-chain saturated triacylglycerols and increased high-melting fraction.

Summary: This study evaluated the impact of different sampling schemes on the estimated daily H2 and CH4 emissions from dairy cattle. Sampling every 0.5 hours was needed for accurate estimation of daily H2 emissions, while less frequent sampling intervals were sufficient for CH4 emissions. The study highlights the importance of accurate sampling schemes for reliable estimation of emissions from cattle.

Summary: The effect of mixed silage on various factors such as chemical composition, ensilability, in vitro cellulase digestibility, and plant secondary metabolites were assessed. The results showed that the fermentation quality of mixed silage made from sugarcane and Mucuna pruriens beans was better than that made from sugarcane and Canavalia ensiformis beans. The ensiling process also decreased the content of plant secondary metabolites.
