Beef tenderness is the most important trait affecting consumer beef eating satisfaction. Cuts from muscles with superior tenderness (tenderloin, ribeye, striploin) are consequently most highly valued, but because of recent record-high beef prices, the need to identify more economical cuts that will meet consumer expectations for tenderness is greater than ever. The eye of round (Semitendinosus) has traditionally been marketed as a lower-value cut, primarily owing to its inherent toughness. Tenderness improves throughout postmortem aging and continues to improve in muscles aged for greater than 35 days. Retail steaks from the Semitendinosus receive, on average, 17 days of aging, with ...


Effects Of Growth-Promoting Technologies On Muscle Structural Characteristics And Meat Tenderness, S. M. Ebarb, J. S. Drouillard, K. J. Phelps, J. A. Noel, M. A. Vaughn, D. D. Burnett, J. M. Gonzalez 2015 Kansas State University

Effects Of Growth-Promoting Technologies On Muscle Structural Characteristics And Meat Tenderness, S. M. Ebarb, J. S. Drouillard, K. J. Phelps, J. A. Noel, M. A. Vaughn, D. D. Burnett, J. M. Gonzalez

Kansas Agricultural Experiment Station Research Reports

Skeletal muscle tissue consists of two main structures that elicit strong influences on cooked meat tenderness: myofibrillar and connective tissues. The myofibrillar component consists of contractile and cytoskeletal proteins that aid in muscle contraction and support. A large portion of meat science literature documents the effects that postmortem aging elicits in terms of weakening the myofibrillar component to improve tenderness. Connective tissue is primarily comprised of collagen, the most abundant protein within the body. The function of this tissue is to support the myofibrillar component and transfer the force of contraction. Collagen, characterized by its solubility, is most commonly identified ...

The use of growth-promoting technologies has become a common practice in the beef cattle industry as producers strive for efficient growth and greater lean deposition. Two common technologies include exogenous hormonal implants and beta-adrenergic agonists (β-AA). Combination implants containing estrogen and testosterone increase muscle mass by elevating protein synthesis and/or reducing protein degradation. The increase in protein synthesis allows the animal to produce more lean muscle tissue. Optaflexx (Elanco Animal Health, Greenfield, IN) is a popular β-AA that works as a repartitioning agent to redirect nutrients toward muscle deposition and away from adipose tissue production. The two technologies utilize ...


Denitrification And Nitrous Oxide Emissions In Annual Croplands, Perennial Grass Buffers, And Restored Perennial Grasslands, Javed Iqbal, Timothy B. Parkin, Matthew J. Helmers, Xiaobo Zhou, Michael J. Castellano 2015 Iowa State University

Denitrification And Nitrous Oxide Emissions In Annual Croplands, Perennial Grass Buffers, And Restored Perennial Grasslands, Javed Iqbal, Timothy B. Parkin, Matthew J. Helmers, Xiaobo Zhou, Michael J. Castellano

Agronomy Publications and Papers

Inclusion of perennial vegetation filter strips (PFSs) in the toeslope of annual cropland watersheds can decrease NO3–N losses to ground and surface waters. Although PFSs are similar to riparian buffers, the processes responsible for NO3–N removal from PFSs are not well understood. Our objectives were to (i) determine the importance of denitrification as a sink for NO3–N loss from PFSs and (ii) evaluate how PFSs alter the biophysical processes that affect the relative importance of N2O and N2 emissions. To address our objectives, we used a coupled field laboratory approach with ...


Comparing Nitrate Sink Strength In Perennial Filter Strips At Toeslopes Of Cropland Watersheds, David C. Mitchell, Xiaobo Zhou, Timothy B. Parkin, Matthew J. Helmers, Michael J. Castellano 2015 Iowa State University

Comparing Nitrate Sink Strength In Perennial Filter Strips At Toeslopes Of Cropland Watersheds, David C. Mitchell, Xiaobo Zhou, Timothy B. Parkin, Matthew J. Helmers, Michael J. Castellano

Agronomy Publications and Papers

Integration of perennial filter strips (PFS) into the toeslopes of agricultural watersheds may decrease downstream nitrate (NO3) losses. However, long-term NO3 removal depends on the relative importance of several NO3 sinks in the PFS. Plant biomass and labile soil organic matter (SOM) are temporary NO3 sinks, while stable SOM is a long-term, but potentially finite, NO3 sink. In contrast, denitrification is a permanent NO3 sink. We investigated the relative importance of these NO3 sinks in PFS at the toeslope of row crop watersheds in Iowa. Using 25- × 30-cm in situ mesocosms, we added ...


Can Peers Improve Agricultural Revenue?, Tisorn Songsermsawas, Kathy Baylis, Ashwini Chhatre, Hope Michelson 2015 University of Illinois at Urbana-Champaign

Can Peers Improve Agricultural Revenue?, Tisorn Songsermsawas, Kathy Baylis, Ashwini Chhatre, Hope Michelson

Kathy Baylis

Crop revenues vary greatly among farmers and the source of that variation is not fully understood. Using a household survey from India, we estimate peer effects on cash crop revenue. Results show that 60% of farmers' revenue can be explained by peers. Peer effects in input expenditure and land allocation cannot fully explain the variation in revenue, implying peers may also associate with management, negotiation and marketing strategies. Although caste-based networks are important, their effect is substantially smaller than that of self-reported peers. Peer effects are strongest for agricultural peers and in the cultivation of a new crop.

Invasiveness Of An Exotic Gall Wasp Is Influenced By Interactions With Exotic And Endemic Organisms, Ignazio Graziosi 2015 University of Kentucky

Invasiveness Of An Exotic Gall Wasp Is Influenced By Interactions With Exotic And Endemic Organisms, Ignazio Graziosi

Theses and Dissertations--Entomology

American chestnut was once a crucial component of North American forests, but it was functionally eliminated by the introduction of the chestnut blight fungus. Chestnut is recently experiencing resurgence, but the introduced Asian chestnut gall wasp, a specialist herbivore, threatens chestnut recovery. I characterized this invasion and the interactions developing with host associates as the gall wasp spread in North America. Gall wasp dispersal is attributable to host plant distribution, effects of prevailing winds during adult insect emergence, and to topography. This knowledge may be useful to more accurately predict locations of future gall wasp infestations. Gall wasp invasiveness is ...

Case Study: Minimizing Food Wastage From Farm To Consumer Products – A Systems Approach, David Masser 2014 University of Pennsylvania

Case Study: Minimizing Food Wastage From Farm To Consumer Products – A Systems Approach, David Masser

The Last Food Mile Conference

Sterman Masser, Inc. is committed to minimizing food loss throughout the process of growing, harvesting, and packaging a consumer ready product through the use of cutting edge technology industry leading techniques. Combining Integrated Pest Management with crop rotations and more resistant potato varieties, SMI has minimized the potential for crop destroying fungi and insects to propagate. In response to hazards from rocks in the soil and the stresses from harvesting we have acquired rock crushers capable of pulverizing everything down to a powder and new harvesters designed to reduce the stresses of harvesting. Potatoes, coming from the fields, enter our ...
