On-Farm Hog Processing Demonstration For Teenage Exhibitors: Blending Academic, Laboratory, And Farm-Based Learning, Katherine A. Wells, Chris L. Bruynis, Lyda G. Garcia

Journal of Extension

COVID-19 challenges induced a U.S. meatpacking industry bottleneck. [University] Extension identified the need and responded by creating a three-step hands-on training for teenage junior fair exhibitors. [University] Extension Meat Scientist and graduate students assisted in demonstrating an on-farm hog harvest and processing event in collaboration with a local Extension office for 4-H and FFA teenagers. To add a practical perspective, a local hog-producing and harvesting family was asked to assist with the event. An online post-survey reflected 90-100% gains in five educational areas and 100% said they would a similar event in the future and recommend it to a friend.

Effects Of Harvest Season On Carcass Characteristics Of Lambs In The Intermountain West, J. R. Whaley, T. W. Murphy, C. L. Gifford, W. J. Means, J. P. Ritten, H. N. Mckibben, C. M. Page, W. C. Stewart

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

Objective: The objectives of this study were to survey characteristics including hot carcass weight (HCW), 12th rib fat thickness (RFT), body-wall thickness (BWT), longissimus muscle area (LMA), USDA yield grade (USDA YG), percentage closely trimmed retail cuts (RC), and calculated yield grade (Calc YG) of lamb carcasses in the Intermountain West to determine the effects of season of slaughter and interrelationships among carcass characteristics.

Materials and Methods: Lamb carcass characteristics were evaluated in 2 commercial Intermountain West processing plants over one year (n = 10,027). Carcasses were evaluated by season: spring (December–April, n = 2,322) and summer (May–August, n …

To continue the series that began in 1994, the National Beef Quality Audit (NBQA) – 2016 was conducted to quantify the quality status of the market cow and bull beef sector, as well as determine improvements made in the beef and dairy industry since 2007. The NBQA-2016 was conducted from March through December of 2016, and assessed hide-on carcasses (n = 5,278), chilled carcasses (n = 4,285), heads (n = 5,720), and offal items (n = 4,800) in 18 commercial processing facilities throughout the United States. Beef cattle were predominantly black-hided; 68.0% of beef cows and 67.2% of beef bulls …

Evaluation Of Absorbezz On Swine Reproductive Health And A Comparative Study Of Two Commercially Available Swine Show Feeds, Scott G. Sutton

Electronic Theses and Dissertations

The efficacy of a feed supplement fed to gilts and sows was tested in study I. The supplement was stated to improve reproductive soundness, conception rates, immune health, and overall well-being of livestock. Thirty gilts were split into a control group (Base diet) and a treatment group (Absorbezz® 0.32 mL on base diet). Upon completion of the trial results indicate the treatment group significantly underperformed (

Two commercially available show pig growing rations were tested in study II to find a high quality, cost efficient product. A total of 10 pigs (5 barrows, 5 gilts), at an average weight of …

National Beef Quality Audit-2016: Transportation, Mobility, And Harvest-Floor Assessments Of Targeted Characteristics That Affect Quality And Value Of Cattle, Carcasses, And By-Products, L.C.

The National Beef Quality Audit-2016 (NBQA-2016) was conducted to assess current transportation, mobility, and quality characteristics of U.S. fed steers and heifers. Data were collected at 17 beef processing facilities between March and November 2016. About 8,000 live cattle were evaluated for transportation and mobility, and about 25,000 carcasses were evaluated on the slaughter floor. Cattle were in transit to the slaughter facility for a mean duration of 2.7 h from a mean distance of 218.5 km using trailers with dimensions ranging from 17.84 m2 to 59.09 m2. Area allotted per animal averaged 1.13 m2 and ranged from 0.85 m2 …

Reducing The Length Of Time Between Harvest And The Secondary Gonadotropin-Releasing Factor Immunization Improves Growth Performance And Clears Boar Taint Compounds In Male Finishing Pig, A K. Lealiifano, John R. Pluske, R R. Nicholls, F R. Dunshea, R G. Campbell, D P. Hennessy, D W. Miller, Christian F. Hansen, Bruce P. Mullan

Animal production and livestock research articles

The objective of this study was to evaluate whether altering the timing of the secondary anti-gonadotropin-releasing factor (GnRF) immunization closer to slaughter in male finishing pigs would reduce the increase in P2 fat depth (6.5 cm from the midline over the last rib), while still limiting the incidence of boar taint. Entire male pigs are immunized against GnRF to reduce the concentration of testicular steroids that in turn limits the incidence of boar taint. Additionally, testicle measurements and color measurements were taken to examine whether they could be used to differentiate nonimmunized entire males from immunized male pigs. A total …

Characterization Of Biological Types Of Cattle (Cycle Viii): Carcass, Yield, And Longissimus Palatability Traits, T. L. Wheeler, L. V. Cundiff, S. D. Shackelford, M. Koohmaraie

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

The objective of this experiment was to evaluate alternative sources of tropically adapted cattle germplasm and compare them with Angus- (AN) and Hereford- (HE) sired steers. Carcass, yield, and longissimus thoracis palatability traits from F₁ steers (n = 621) obtained from mating AN and United States Meat Animal Research Center III cows to HE, AN, Brangus (BR), Beefmaster (BM), Bonsmara (BO), or Romosinuano (RO) sires were compared. Data were adjusted to constant age (426 d), carcass weight (340 kg), fat thickness (1.0 cm), fat trim percentage (25%), and marbling (Small⁰⁰) endpoints. For Warner- Bratzler and slice …

South Dakota Beef Report, 1986

Angus bulls averaging 620 lb were used to study the effects of implants on performance, carcass characteristics and reproductive parameters of intact males. Sixty-six bulls were randomly assigned to four treatments. These treatments were (1) nonimplanted, (2) implanted with 36 mg of Ralgro every 60 t o 70 days, (3) implanted with 220 mg of Synovex-S every 60 t o 70 days, (4) implanted with 24 mg of Compudose every 180 days. Body weights were taken a t the initiation of the trial and every 28 days. Blood samples were collected v i a jugular venipuncture weekly for 9 weeks …
