Comparison Of Ivermectin And Extended-Release Eprinomectin Deworming Treatment On Stocker And Subsequent Feedlot Performance And Carcass Characteristics Of Fall-Born Angus Heifers, Christopher A. Clark, Patrick J. Gunn, Joe Dedrickson, Jerry Sorenson

Iowa State Research Farm Progress Reports

Severe parasite infections in beef cattle are sometimes associated with decreased growth and performance and clinical disease. Stocker cattle are exposed to many parasites and appropriate deworming strategies can help to minimize parasite burdens when cattle are on grass. Feedlot cattle are often dewormed at arrival and have minimal exposure to additional parasites once placed in the feedlot. The purpose of this study was to evaluate stocker and feedlot performance and carcass characteristics relative to treatment with deworming agents of varying durations of activity.

Iowa State Research Farm Progress Reports

Consumer interest in the potential benefits of grass-finished beef is high, but adoption of this approach to cattle feeding has been limited in Iowa. Although some producers successfully meet this niche market demand, consistently producing a high-value carcass from forage-fed cattle is challenging. Intramuscular fat or marbling is a major factor in quality grading of beef. Marbling is heavily influenced by cattle genetics and energy concentration of the diet. Finishing cattle on grain is a proven approach to consistently produce a high-value carcass for the commodity beef market. Researchers at Iowa State University have pioneered the use of ultrasound measurements ...

Effects Of Calf Age And Dam Age On Circulating Bvdv Ii Antibody Levels Prior To Vaccination In Angus Weanling Calves, Erika Diane Downey, Richard G. Tait Jr., Mary Sue Mayes, Dorian J. Garrick, Julia Ridpath, James M. Reecy

Iowa State Research Farm Progress Reports

Newborn calves passively acquire antibodies from their dams via consumption of colostrum immediately after birth. Colostrum quality and quantity may differ by dam age affecting the amount of circulating maternally derived antibodies. The objective of this study was to evaluate if there are differences in calf titers of maternal antibodies based on age of dam and age of calf. This knowledge is important for determining vaccination strategies because passively acquired antibodies for bovine viral diarrhea virus I and II (BVDV) have been shown to block the ability of calves to develop their own specific immune response to BVDV.

Cattle Temporal And Spatial Distribution In Midwestern Pastures Using Global Positioning (Three-Year Progress Report), Douglas A. Bear, James R. Russell, Daniel G. Morrical

Iowa State Research Farm Progress Reports

Previous research has shown that grazing cattle tend to congregate in streamside 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 the development and implementation of management practices that minimize nonpoint source pollution possibly associated with grazing cattle.

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.

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.
