The meeting was called to order at 9 a.m.  Voting members present were Stan Melroe, Lyle Warner, Allan Tellmann, Steve Metzger and Raymond Erbele. Non-voting members present were Dr. Greg Lardy and Dr. David Buchanan.  Also present was Lori Capouch

 

The committee appointed Steve Metzer to chair the meeting by consensus.

 

The committee briefly discussed the guidelines for the Agricultural Research Fund and procedures for conducting the meeting.

 

The following presentations were heard:

 

Global gene regulation in Escherichia coli 0157:H7 on the surface of beef

Researcher: Birgit Pruess

Amount requested:  $10,000

 

The Escherichia coli isolate 0157:H7 is a highly virulent pathogen and one of the predominant causes of E. coil associated food-borne disease in the United States.  With this project, researchers will start the development of a new antimicrobial spray that constitutes a nutrient or metabolic intermediate for the bacteria that they will find harder to become resistant against. This nutrient or metabolite when sprayed on the surface of the beef will affect cellular processes, such as cell division or acid resistance.  The new sprays could be used alone or in combination with one of the current acid sprays.

 

Impact of cattle health on beef quality

Researcher: Robert Maddock

Amount requested: $6,500

 

The health of cattle in feedlots may be an important factor affecting the value, tenderness, and taste of beef.  Researchers propose to examine the relationship between cattle health and meat quality.

 

Effects of an integrated crops/livestock system on beef cow growth performance, soil quality and economic risk

Researcher: Eric Scholljegerdes

Amount requested:  $10,229

 

The objectives of this project are to determine whether cows can effectively be grown on annual crops compared to perennial grass plus hay feeding or Altai wild rye.  In this trial, researchers will use 42 Angus cows divided up into eight cows per pasture and two pastures per treatment. Treatments will be 1) grass pasture plus hay feeding (control); 2) Altai wild rye continuously grazed; or 3) swath grazing annual crops.  This experiment will evaluate the effects of these feeding systems on animal performance, soil quality, and economic indicators.

 

Impacts of fatty acid supplementation prior to breeding on circulating progesterone and prostaglandin F2apha metabolite concentrations in beef heifers

Researcher: Kimberly Vonnahme

Amount requested: $6,720

 

Hormone analysis will be performed to determine if diet modulates reproductive success.

 

Impacts of maternal exercise on litter size, offspring growth, and muscle fiber characteristics

Researcher:  Kimberly Vonnahme

Amount requested: $10,270

 

The objective of this project is to determine if exercise during pregnancy may influence meat quality in offspring

 

Ruminal by-pass supplementation of L-Arginine in ruminants: impacts on reproduction

Researcher: Joel Caton

Amount requested: $8,860

 

This project is designed to provide baseline data evaluating targeted by-pass amino acids fo supplementation to ruminant livestock.

 

Development of quantitative methods of evaluating analgesic drug efficacy in lame dairy cows

Researcher: Sarah Wagner

Amount requested:  $5,337

 

This project was withdrawn.

 

Odor setback estimation tool from livestock and poultry facilities in North Dakota

Researcher: Shafiqur Rahman

Amount requested:  $15,000

 

The objective of this study is to develop a science based method to estimate odor setback distance from livestock and poultry production facilities and the surrounding area.

 

Nutrient levels in stockpiled and composted livestock and poultry manure in North Dakota livestock operations

Researcher: Shafiqur Rahman

Amount requested: $14,000

 

The objective of this project is to measure nutrient contents of manure from different livestock and poultry species (i.e. beef, dairy, swine, sheep, bison and poultry) as stockpiled/stored, and composted in North Dakota livestock operations.

 

Rabies in North Dakota: rapid diagnosis and risk factors associated with infection

Researcher: N.W. Dyer

Amount requested: $13,740

 

The project is based on two primary objectives: 1) the development of a polymerase chain reaction (PCR) assay which can be added to the existing rabies diagnostic menu at the NDSU-VDL.  This would allow for more accurate diagnosis, particularly in cases where decomposed tissue has been submitted for testing.  This process will require a validation process which compares results from existing test methods in the lab to the new assay. 2) Analysis of epidemiologic information which will contribute to researchers’ knowledge of risk factors associated with exposure to the rabies virus.  This information has recently become more important as medical providers no longer are able to routinely dispense post exposure rabies treatment for people who feel they have had exposure to the virus.  The epidemiologic survey will provide information which can reduce public exposure to the virus.

 

Does post-fasting hyperphagia in finishing swine improve feed utilization, rate of gain,a nd reduce feed production costs?

Researcher: Eric Berg

Amount requested: $10,290

 

This study will examine if cyclical fasting improves rate of gain, feed efficiency, and shortens days to market of finishing swine.

 

Influence of level of distillers grains plus soluble on animal performance, carcass characteristics, sulfur balance and ruminal hydrogen sulfide gas concentration in ruminants

Researchers: Christopher Schauer & Bryan Neville

Amount requested: $17,040

 

This project will look at the effects increasing dried distillers grains plus soluble have on animal performance, carcass characteristics, sulfur balance, and hydrogen sulfide gas concentrations in ruminants.  Sulfur balance will be evaluated in lambs fed a finishing ration containing 0, 20, 40 or 60 percent DDGs.  Lambs as well as beef steers will also be used to evaluate the ruminal hydrogen sulfide gas concentrations when feeding these diets.  Steers will be fed to a slaughter weight at which time animal performance and carcass data will be collected and analyzed.

 

Genome sequence analysis of Campylobacter fetus associated with human infection and bison abortion

Researcher: Catherine Logue

Amount requested: $25,000

 

(A formal presentation was not given for this project.)

This project is seeking funds to complete whole genome analysis of a sequenced Campylobacter fetus strain recovered from a human aneurysm case in North Dakota – there have been only thirteen such cases in the world and this isolate may be potentially linked to animal production exposure.  Researchers completion of the genome will allow them to exploit its potential for vaccine development and methods for treatment of animal and human disease.

 

Effect of initial creep-fed DFM on e. coli 0157:H7 proliferation and shedding when fed from pasture to final harvest

Researcher: Doug Landblom

Amount requested: $12,331

 

The research team hypothesizes that the continuous feeding of the direct fed microbials Lactobacillus acidophilus (LA-51) and propionibacterium freudenreichii (PF-24) on pasture and continuing through the final harvest will compete for rectal mucosal binding sites competitively excluding colonization capabilities of pathogenic e. coli 0157:H7 and other pathogenic serotypes.

 

Evaluation of low-input growing and finishing options for cattle producers

Researcher: Vern Anderson

Amount requested: $9,105

 

North Dakota cattlemen can capture more value from the exceptional genetics for growth and carcass merit in their calves.  New markets are developing in the state for finished beef and demand is good for locally produced meat. However, cow/calf producers with minimum facilities or smaller herds cannot easily or economically feed their calves after weaning.  Self-feeding minimizes equipment, labor and facilities costs and can be very safe with higher levels of co-products.  There is no comparative data available for self-feeding with modern cattle, feed products and nutritional knowledge.  This study proposes to compare performance and economics of feeder cattle with exceptional genetic potential fed in self-feeders or fed totally mixed rations delivered to fence line bunks daily.

 

Effect of feeding regimes on net profit for diverse entry weight feeder cattle

Researcher: Vern Anderson

Amount requested: $20,360

 

There is a wide variation in the weight of weaned calves with some herds calving later, and some maximizing genetics for growth.  Feedlots in North Dakota have a smorgasbord of feeds available including home grown forages and silages, a variety of co-products, protein sources and grains. Calves enter the feedlot from 350 lbs. to over 800 lbs. at weaning. Feeding regimes designed for maxim profit are probably not the same for this diversity of type and maturity.  This project proposes to compare modest gain and high gain treatments for both groups of calves in a scientifically valid design that will yield growth performance data, carcass quality traits and economic comparisons.  Calves from several North Dakota cow herds will be used for this study with a sampling of the largest calves and the smallest calves from the same herds constituting the populations sample. Data from this study will reveal the optimum feeding strategy for farmer feeders who want to background their calves and maybe retain ownership in the finishing yard, as well as feed yards that would buy weaned calves of diverse entry weights or heavier preconditioned feeder cattle.

 

Funding decisions

 

Steve Metzger declared a potential conflict of interest for the following projects.  Mr. Metzger will not be benefitting financially from either project:

 

            Evaluation of low-input growing and finishing options for cattle producers

 

            Effect of feeding regimes on net profit for diverse entry weight feeder cattle

 

Dr. Greg Lardy declared a potential conflict of interest for the following projects.  Dr. Lardy will not be benefitting financially from either project, he is serving as a mentor:

 

            Nutrient levels in stockpiled and composted livestock and poultry manure in North

            Dakota livestock operations

 

            Influence of level of distillers grains plus soluble on animal performance, carcass

            characteristics, sulfur balance and ruminal hydrogen sulfide gas concentrations in

            ruminants

 

It was the consensus of the committee that both committee members’ conflicts were not substantial enough to dismiss them from the meeting while the projects were being discussed.

 

The committee members discussed each project as a whole and then individually ranked the projects 1-3-5 with “1” representing the highest ranked proposals.  The individual rankings were used to determine the overall ranking of each project.

 

It was moved by Warner and seconded by Tellmann to grant negotiated funding as follows:
