Managing Pig Feed Costs In Niche Pork Production, Mark S. Honeyman, Peter J. Lammers, Sherry Hoyer

Iowa Pork Industry Center Fact Sheets

The rising price of corn has created increased interest in alternative feedstuffs by livestock producers, and niche market pork producers are no exception. Unfortunately, there is currently no single replacement for corn in Midwest pig diets, even at today’s market prices. Thus, managing factors that you can more easily control is critical for continued success in pork production.

Evaluation Of Mixing Wet Distillers Grains With Ground Hay In A Bunker And Covering Modified Distillers Grains To Extend Storage Life—A Demonstration Project, Daryl R. Strohbehn, Daniel D. Loy, Joe Sellers, Kevin Maher, Dennis R. Maxwell

Iowa State Research Farm Progress Reports

The ethanol industry is rapidly expanding. As much as 40 percent of the energy cost is associated with drying of the feed co-products. Distillers grains are excellent sources of nutrients for the diets of beef cattle, but have a short shelf life. To expand the use of wet distillers feeds to more producers, longer term, low-cost storage methods are required. Studies done in 2006–2007 showed that bagging these products was an effective management practice, but was higher in cost than acceptable to some producers. Additionally, availability of bagging equipment is limited, thus encouraging other storage methodologies to be investigated.

Iowa State Research Farm Progress Reports

Cow-calf producers are asking questions concerning the use of wet distillers grain in their operations. Most small to moderate sized cow-calf producers cannot use a semi-load of wet distillers grain fast enough before it spoils, therefore, methods for extended storage are needed to use this product in their operation. Previous feedlot work suggested distillers grain are excellent sources of nutrients for the diets of feedlot cattle, but have not been used to a large degree in heifer development programs. The goal of this trial was to evaluate the use of modified distillers grain with solubles mixed with ground hay and ...

The sustained growth of the ethanol industry in the upper Midwest is well documented. There are many ways this affects the cattle industry. Increased demand for corn by the industry has driven prices to record highs in 2008. The increased cost and demand for corn have forced cattle producers to evaluate the many ways to use the by-products produced by the ethanol industry. Increased ethanol production has led to larger supplies of the byproduct dried distillers grains with solubles (DDGS). Companies have started to market pelleted versions of this product that may be economical for cattle producers to use to ...


Cattle Temporal And Spatial Distribution In Midwestern Pastures Using Global Positioning (A Progress Report), Douglas Allen Bear, James R. Russell Jan 2009

Cattle Temporal And Spatial Distribution In Midwestern Pastures Using Global Positioning (A Progress Report), Douglas Allen Bear, James R. Russell

Iowa State Research Farm Progress Reports

Previous research has shown that grazing cattle tend to congregate in riparian zones of pastures to obtain water and shade for thermoregulation. However, problems associated with thermoregulation may be increased because of the presence of endophyte-infected tall fescue in pastures. Defining relationships between cattle distribution, such pasture characteristics as size, shape, shade distribution, botanical composition, and climatic factors related to heat stress, will provide the basis for development and implementation of management practices that minimize nonpoint source pollution possibly associated with grazing cattle.


Modifying An Outdoor Farrowing Hut For Alternative Indoor Farrowing During Summer And Winter, Mark S. Honeyman, Lyle T. Rossiter Jan 2009

Modifying An Outdoor Farrowing Hut For Alternative Indoor Farrowing During Summer And Winter, Mark S. Honeyman, Lyle T. Rossiter

Iowa State Research Farm Progress Reports

Niche pork markets have expanded rapidly. In the Midwest, frequently there are shortages of pigs born in the winter and summer and surpluses of pigs born in spring and fall. Most producers can meet the niche market requirements by farrowing outdoors in spring and fall. But farrowing outdoors in Midwest winters is difficult. Winter-farrowed sows will also farrow in the hot summer months, another challenging time due to heat and humidity. Therefore, the objective of this project was to modify an outdoor farrowing hut for winter and summer farrowing indoors to meet niche pork market requirements.

Environmental Factors Impacting Response To Bovine Viral Diarrhea Vaccines In Angus Calves, Matthew Schneider, Richard G. Tait Jr., James M. Reecy, Julia Ridpath

Iowa State Research Farm Progress Reports

Bovine respiratory disease is a very significant disease affecting feedlot cattle across the US. We are interested in investigating the genetic control of response to respiratory disease vaccines as a method of reducing respiratory disease in feedlots in the future. When beginning to investigate genetic control of a new trait, it is important to characterize nongenetic effects on that trait. Therefore, the objective of this study was to evaluate the impact of environmental factors on the serological response to vaccination for a commercial bovine viral diarrhea (BVDV2) vaccine.

Iowa State Research Farm Progress Reports

This study looked at the use of condensed corn distillers solubles (CCDS) as a feed source for steers backgrounded on pasture as well as steers being fed in the feedlot. In addition, a treatment group was finished on pasture with CCDS as a part of their ration. The two feedlot rations were isocaloric and isonitrogenous. The pasture finishing steers were fed a ration based on the feedlot ration containing CCDS but were not fed any hay. The goal of this study was to establish the benefits, as well as the limitations, of feeding CCDS to feedlot and backgrounded steers.
