- ... Wet distiller‘s grains with solubles (WDGS) are a common feed ingredient in beef feedlot diets but the high nitrogen content of these diets creates air quality issues, primarily due to the aromatic compounds emitted during protein fermentation. Use of high moisture corn (HMC) instead of dry-rolled corn (DRC) in cattle feedlot diets has been shown to reduce some odors associated with excess starch ...

- ... BACKGROUND: Marbling, or intramuscular fat, is an important factor contributing to the palatability of beef. Vitamin A, through its active metabolite, retinoic acid, promotes the formation of new fat cells (adipogenesis). As intramuscular adipogenesis is active during the neonatal stage, we hypothesized that vitamin A administration during the neonatal stage would enhance intramuscular adipogenesi ...

- ... The present study compared ammonia (NH₃) emissions from Canadian beef production in 1981–2011. Temporal and regional differences in cattle categories, feed types and management systems, average daily gains, carcass weights, and manure handling practices were considered. A scenario-based sensitivity analysis in 2011 estimated the impact of substituting corn dried distillers’ grains with solubles (D ...
