Flooding And Stored Grain, Charles R. Hurburgh, Daniel D. Loy Jun 2008

Flooding And Stored Grain, Charles R. Hurburgh, Daniel D. Loy

Integrated Crop Management News

Floodwaters have soaked many grain bins on farms and at commercial elevators. With only a few exceptions, flood soaked grain is not useable for feed or food. Flooding affects both the stored grain and the storage structures.


A Comparison Of Alternative Winter Farrowing Systems, Mark S. Honeyman, Randy Breach, Lyle T. Rossiter Jan 2008

A Comparison Of Alternative Winter Farrowing Systems, Mark S. Honeyman, Randy Breach, Lyle T. Rossiter

Iowa State Research Farm Progress Reports

Niche pork markets have expanded rapidly. Many of the niche pork markets are seasonally short of pigs born in the winter months. The purpose of this demonstration was to compare two alternative winter farrowing systems that meet niche pork production criteria.


Impact Of Grazing Management On Cattle Distribution And Physical Characteristics Of The Riparian Zones Of Pastures, Mathew M. Haan, James R. Russell, Douglas A. Bear Jan 2008

Impact Of Grazing Management On Cattle Distribution And Physical Characteristics Of The Riparian Zones Of Pastures, Mathew M. Haan, James R. Russell, Douglas A. Bear

Iowa State Research Farm Progress Reports

Grazing management practices that allow cattle to congregate near pasture streams may result in the loss of vegetative cover and accumulation of manure near pasture streams. These conditions may cause loading of the streams with sediment, phosphorus, and pathogens carried in surface runoff. The loss of vegetation and increased compaction associated with concentrated cattle traffic may promote stream bank erosion causing further impairment of stream water quality. The objectives of the current study were 1) to evaluate cattle distribution patterns, in relation to a pasture stream/pond and 2)to evaluate the effects of stocking rate and the botanical composition ...

Development Of Methodologies To Reduce The Dcad Of Hay For Transition Dairy Cows, Ronald L. Horst, Kenneth T. Pecinovsky, Jesse Goff Jan 2008

Development Of Methodologies To Reduce The Dcad Of Hay For Transition Dairy Cows, Ronald L. Horst, Kenneth T. Pecinovsky, Jesse Goff

Iowa State Research Farm Progress Reports

Ration formulation for dairy cows prior to parturition must control the diet cation-anion difference (DCAD) if hypocalcemia and milk fever are to be avoided. One key to reducing hypocalcemia is to avoid incorporation of high K forages into the ration. The excessive K content of these forages can cause metabolic alkalosis in the cow and subsequently hypocalcemia and milk fever. Alfalfa and other cool season grasses are often used in dairy rations. Reducing K content of forages can be achieved by restricting K fertilization so that soils do not support luxury K consumption by the crops. Because K is the ...


Evaluation Of Bagging To Extend Storage Life Of Wet And Modified Distillers Grains—A Demonstration Project, Daryl R. Strohbehn, Daniel D. Loy, Daniel G. Morrical, Joe Sellers, Dennis R. Maxwell Jan 2008

Evaluation Of Bagging To Extend Storage Life Of Wet And Modified Distillers Grains—A Demonstration Project, Daryl R. Strohbehn, Daniel D. Loy, Daniel G. Morrical, Joe Sellers, Dennis R. Maxwell

Iowa State Research Farm Progress Reports

The ethanol industry is rapidly expanding. As much as 40% of the energy cost is associated with drying 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 storage methods are required.


Feeding Ddgs To Finishing Pigsin Deep-Bedded Hoop Barns, Mark S. Honeyman, David R. Stender, Wayne B. Roush, Don Hummel Jan 2008

Feeding Ddgs To Finishing Pigsin Deep-Bedded Hoop Barns, Mark S. Honeyman, David R. Stender, Wayne B. Roush, Don Hummel

Iowa State Research Farm Progress Reports

The ethanol industry in Iowa has rapidly expanded in the last several years. A major coproduct of ethanol production is dried distillers grains with solubles(DDGS). Higher prices for corn and ample supplies of DDGS has generated interest in feeding DDGS to finishing pigs. Challenges in feeding DDGS supplemented diets to finishing swine include problems of feed flowability in bulk bins and feeders, reduced feed intake, and softer, oilier fat in pork carcasses. Pelleted diets have improved flowability and may stimulate feed intake, but thus far no studies have examined feeding DDGS-supplemented dietsin pelletted form to pigs. The objective of ...


Effects Of Feeding Iowa-Grown Field Pea On Finishing Pig Performance, Josephat G. Njoka, Mark S. Honeyman, Thomas G. Miller Jan 2008

Effects Of Feeding Iowa-Grown Field Pea On Finishing Pig Performance, Josephat G. Njoka, Mark S. Honeyman, Thomas G. Miller

Iowa State Research Farm Progress Reports

Field peas(Pisum sativum L.) are a valuable and versatile nutrient source for a range of livestock species in several regions of the world. Interest in growing field peas as a feedstuff for livestock is increasing in the upper Midwest. Peas are a relatively new crop in Iowa where corn and soybean meal are the primary ingredients of swine diets. The growing season,seed characteristics, and other agronomic factors influence the nutrient content of peas. Hence, it is important to understand the nutrient levels of locally grown peas before incorporating them in swine diets.
