Use of zilpaterol hydrocholoride to reduce odors and gas production from the feedlot surface when beef cattle are fed diets with or without ethanol byproducts

Purpose

Many malodorous compounds emitted from the feedlot surface of beef finishing facilities result from protein degradation of feces and urine (Mackie et al., 1998; Miller and Varel, 2001, 2002). The inclusion of wet distillers grain with solubles (WDGS) in beef finishing diets has been shown to increase nitrogen excretion (Spiehs and Varel, 2009; Hales et al.,…

Modeling water movement in beef cattle bedded manure pack


Why Examine Moisture Content of a Manure Pack?

Bedded manure is a valuable fertilizer source because it contains essential macronutrients (nitrogen (N), phosphorus (P), and potassium (K)) for crop production. Previous research with beef cattle bedded manure packs demonstrated that water-soluble macronutrients accumulated toward the bottom of the packs with water movement.…

Mono-Slope Beef Barns

There is growing interest in feeding cattle in bedded confinement buildings for a multitude of reasons including (but not limited to): performance advantages, limited space for open lots, and keeping manure dry as well as preventing feedlot run-off and reducing environmental concerns. Oftentimes these confined cattle are housed in mono-slope barns.…
