Choline is vital in a variety of physiological processes that influence brain development, growth, and carcass characteristics in birds and mammals. In this study, we investigated the influence of graded supplemental choline chloride on growth performance, carcass quality, and liver characteristics in grow-finish pigs. Pigs (672 barrows and 588 gilts) were obtained from a commercial nursery facility at 8 weeks of age and assigned to treatment based on body weight and sex, with 21 same-sex pigs comprising a replicate pen. Each dietary treatment was provided to 15 replicate pens, with 8 pens of barrows and 7 pens of gilts per each of 4 dietary treatments, which included: 1) C0, basal diet containing 0% of supplemental choline chloride; 2) C300, C0 + 0.06% supplemental choline chloride, to provide 300 mg/kg of choline ions; 3) C600, C0 + 0.12% supplemental choline chloride, to provide 600 mg/kg of choline ions; and 4) C900, C0 + 0.17% supplemental choline chloride, to provide 900 mg/kg of choline ions. Feed and water were provided ad libitum throughout the study, and pigs were managed using standard commercial practices. Data were analyzed by two-way ANOVA using the MIXED procedure of SAS, with factors including dietary treatment and sex. There was no dietary impact (P > 0.05) on growth performance. Pigs receiving intermediate levels of supplemental choline had higher (P < 0.05) tenderloin weights compared with other dietary treatments. Furthermore, and as expected, sex differences were denoted in both growth performance and carcass characteristics. Overall, graded supplementation of choline chloride did not significantly alter growth performance or carcass characteristics of pigs raised in a commercial setting.

Background: Supplementing choline and docosahexaenoic acid (DHA) to pregnant gilts modified fetal pig hepatic global DNA methylation induced by gestational malnutrition, suggesting that gene expression and regulation and its associated metabolic pathways are affected in the liver of offspring during growth and development.
Objective: To investigate the effect of maternal supplementation of choline, DHA and their interaction on hepatic mRNA expression, miRNA regulation and metabolic pathways in the fetal pigs born to malnourished mothers.
Methods: The abundance of mRNA and miRNA was profiled in fetal liver from sows with undernutrition supplemented with choline and DHA in a 2 × 2 factorial design.

Fatty liver impairs liver function and reduces productivity in dairy cows. Our previous in vivo findings demonstrated that branched-chain amino acids (BCAA) or branched-chain ketoacid (BCKA) improved liver function and lactation performance in dairy cows; however, the underlying mechanisms remain unclear. This study aimed to assess the impact of BCAA or BCKA supplementation on intracellular triglyceride (TG) accumulation, lipid metabolism, antioxidant response, and apoptosis in hepatocytes.

Background: Pregnancies complicated by maternal obesity are characterized by metabolic differences affecting placental nutrient transport and fetal development. Docosahexaenoic acid (DHA) is critical for fetal brain development and is primarily incorporated into phosphatidylcholine (PC). Recent evidence suggests that choline may enhance PC-DHA synthesis; however, data on the impact of maternal plasma choline on placental phospholipid DHA content in females with obesity are limited.

Background: Bacterial pathogens frequently encounter host-derived metabolites during their colonization and invasion processes, which can serve as nutrients, antimicrobial agents, or signaling molecules for the pathogens. The essential nutrient choline (Cho) is widely known to be utilized by a diverse range of bacteria and may undergo conversion into the disease-associated metabolite trimethylamine (TMA). However, the impact of choline metabolism on bacterial physiology and virulence remains largely unexplored.
