Department of Animal Science: Faculty Publications

No information is currently available on the profile of producers and production process of dry-aged beef in Brazil, to the best of the authors’ knowledge. We surveyed 37 Brazilian companies that were producing dry-aged beef in 2020 to investigate this market. The absolute and relative frequency of responses was calculated to obtain the sum, average, minimum, and maximum values. From the respondents, dry-aged beef was first produced in 2009, and most producers are located in big cities. Most respondents control and monitor chamber temperature; however, humidity and air velocity only are monitored. The aging period (mostly between 22 to 60 …

Use Of Bedding Materials In Beef Bedded Manure Packs In Hot And Cool Ambient Temperatures: Effects On Ammonia, Hydrogen Sulfide, And Greenhouse Gas Emissions, Jeff P. Jaderborg, Mindy J. Spiehs, Bryan L. Woodbury, Alfredo Dicostanzo, David B. Parker

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Throughout the Upper Midwest, producers have observed increased land and fertilizer prices, resulting in increased popularity of confinement feeding facilities such as mono-slope and hoop barns with bedded packs. Environmental and public pressure has been placed on the agriculture community to reduce ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gas (GHG) emissions from concentrated animal feeding operations (CAFOs). This study was conducted to determine the effects of bedding material (corn stover (CS), bean stover (BS), wheat straw (WS), or pine wood chips (PC)) and ambient temperature (15°C (COOL) or 30°C (HOT)) on NH3, CH4, CO2, N2O, and H2S flux in …

Use Of Bedding Materials In Beef Bedded Manure Packs At Hot And Cold Ambient Temperatures: Effects On Odorous Volatile Organic Compounds And Odor Activity Values, Jeff P. Jaderborg, Mindy J. Spiehs, Bryan L. Woodbury, Alfredo Dicostanzo, David B. Parker

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Beef cattle producers are beginning to raise cattle in confinement facilities such as slatted-floor barns, hoop barns, and mono-slope facilities. Hoop and mono-slope facilities typically use bedding packs as part of their manure management system, with crop residues being the most commonly used bedding material. This study was conducted to determine the effects of bedding material, i.e., corn stover (CS), bean stover (BS), wheat straw (WS), or pine wood chips (PC), and environmental ambient temperature, i.e., cold (15°C) or hot (30°C), on the concentrations of odorous volatile organic compounds (VOCs) in air samples collected in the headspace above lab-scale bedded …
