Maternal Undernutrition Affects Fetal Thymus DNA Methylation, Gene Expression, and, Thereby, Metabolism and Immunopoiesis in Wagyu (Japanese Black) Cattle.

We aimed to determine the effects of maternal nutrient restriction (MNR) on the DNA methylation and gene expression patterns associated with metabolism and immunopoiesis in the thymuses of fetal Wagyu cattle. Pregnant cows were allocated to two groups: a low-nutrition (LN; 60% nutritional requirement; = 5) and a high-nutrition (HN; 120% nutritional requirement, = 6) group, until 8.5 months of gestation.

Effects of nicotinamide riboside feeding on high-yield broiler performance, meat quality, and myopathy incidence.

The objective of this study was to examine the effects of nicotinamide riboside (NR) feeding on high-yield broiler growth and meat quality. Fertilized Cobb 700 by-product eggs ( = 3,240) were randomly assigned to one of four in ovo treatments and injected with 0 (), 250 (), 500 (), or 1,000 () mM NR at incubation-day 10. Chicks were hatched, vent sexed, and randomly placed 18 per pen in one of 32 floor pens.
