Construction And Ventilation Of Dairy Barns., C. F. Curtiss

Bulletin (Iowa Agricultural Experiment Station)

The importance of efficient ventilation of dairy barns has been emphasized by the recent investigation of the causes conducive to the development and contagion of tuberculosis in cattle. Bulletin No. 7, of United States Bureau of Animal Industry, on Investigations Concerning Bovine Tuberculosis, says: “Fully nine-tenths of all diseased animals have been infected by inhaling the tubercle bacilli dried and suspended in the air.” Without proper ventilation the tubercle bacilli and other disease germs must be much more readily inhaled, and it is a matter of record that the worst diseased herds are found in poorly lighted and poorly ventilated ...


Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin 2017 University of Tennessee, Knoxville

Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

Tractor rollovers are a leading cause of death in the agricultural industry. While rollovers continue to happen, Roll-Over Protective Structures (ROPS) have shown great ability to prevent or reduce the casualties and injuries associated with rollover events. One authority on the subject even goes so far as to claim that “that fatality rates due to tractor overturns could be reduced by a minimum of 71% if all tractors in the U.S. were equipped with ROPS,” (NIOSH, 2009). The potential of this promising statistic has been devalued slightly due to the misapplication of foldable ROPS by leaving the ROPS in ...

Reduction Of Particulate Matter And Ammonia By Spraying Acidic Electrolyzed Water Onto Litter Of Aviary Hen Houses: A Lab-Scale Study, Lilong Chai, Yang Zhao, Hongwei Xin, Tong Wang, Atilgan Atilgan, Michelle Soupir, Kai Liu

Tong Wang

Particulate matter (PM) concentrations are high in cage-free aviary hen houses due to accumulation of litter on the floor and hen activities. The use of a spraying agent such as acidic electrolyzed water (AEW) to mitigate PM levels and disinfect houses has been reported, and high spray dosages will reduce PM to a low level. However, spraying a high dose of AEW may generate high levels of ammonia (NH3) due to an increase in litter moisture content (LMC). Lab-scale experiments were conducted to assess the effect of AEW spray dosage and pH on PM and NH3 emissions from the litter ...

Cross-Institutional Exploratory Of Faculty Compensation Models To Incentivize Distance Learning Participation, Mitchell L. Springer, Mark T. Schuver, Thomas J. Brumm

Thomas J. Brumm

In higher education, courses and curriculum are purportedly the intellectual property of the academic departments. Academic departments, then, provide instructors or faculty to teach. The assignment of faculty to teach in distance-based programs directly implies there needs to exist some level of financial incentive for the home department of those faculty, as well as direct incentive to the faculty who are involved in teaching. After all expenses are accounted for, then,what model for faculty compensation provides the greatest level of incentive to participate in professional studies? Building on previous scholarship and over a year of additional research,this paper ...


Grain Test Weight Deception, Carl J. Bern, Thomas J. Brumm 2017 Iowa State University

Grain Test Weight Deception, Carl J. Bern, Thomas J. Brumm

Thomas J. Brumm

Test weight is used as an indicator of general grain quality and is a measure of grain bulk density. Test weight, but not overall grain weight, normally increases during drying. Erroneous calculations using test weights can incorrectly infer that drying systems that increase test weight also increase the number of bushels that can be sold. This bulletin explains the use of test weight in the grain industry, how it can be used to determine grain value, and why some calculations involving test weight can be deceptive.

Use Of Recycled Containers For Hermetic Maize Storage In East Africa, A. Yakubu, L. A. Wilson, C. J. Bern, T. J. Brumm

Thomas J. Brumm

Affordable, pesticide-free, and reliable maize storage containers for seed and food purposes are not available in many subsistence farming cultures. As a result, subsistence farmers lose their crop to pests and are forced to dispose of their maize for a low price right after harvest thus, robbing them of profit and food for the rest of the year. The objective of this research was to develop information to enable utilization of recycled sanitary hermetic maize storage containers. Use of these containers will allow farmers to preserve their maize for as long as they wish, using locally available resources. A market ...

Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)

This investigation included a 6-year study of the effects of irrigation, stand and fertility treatments on com yields on a clay loam soil near Ames, Iowa. The data obtained from 1956 to 1961 indicated that variations in yields were caused by all three variables. Significant yield differences caused by irrigation treatments were greatest in 1956, 1959 and 1960. The highest mean irrigated yields averaged over stand and fertility treatments usually correlated best with the irrigation treatment where the soil moisture was maintained at or above 60 percent of the available moisture content (AMC). The greatest yield response to irrigation occurred ...

Steven K. Mickelson

Non point-source (NPS) pollution is a major cause of surface water quality degradation due to the transport of chemicals, nutrients, and sediments into lakes and streams. Vegetative buffers comprise several effective landscape Best Management Practices (BMPs) that include Vegetative Filter Strip (VFS) buffers, grassed waterways, terraces, and wetlands. However, some BMPs are ineffective due to concentrated surface flow, improper cropland/contributing area to VFS buffer area ratios, and flowpaths that completely bypass vegetative buffers. The primary objective of this study was to assess the effectiveness of VFS buffers and other vegetative BMPs to intercept surface runoff by quantifying the accuracy ...
