Meeting Minutes

Tuesday, May 17^th- General gathering and introduction of new members and guests. Review committee meeting agenda and discuss priority areas. Wednesday, May 18^th- Met at Iowa State University, Kildee Hall. Welcome by Don Beermann, department chair. Administrative report from John Lawrence in person, and NIFA report from Steve Smith via video conference.  Considerable discussion about potential collaboration between committee members, including topics such as antibiotic alternatives, water needs, and information needed to help support new NRC. Experiment Station Reports were held over the two day meeting- Faculty from the 11 institutions that attended the meeting presented research focused on the challenges and opportunities in each state. Much of the summarized research fell within the specific goals of the NCCC-308 committee. Wednesday afternoon included a tour of Summit Farms, Alden, Iowa, including confined cow operations and farm to feedlot operations. Also toured Iowa State University Beef Nutrition Research Farm. Thursday May 19^st- Luis Tedeschi, Texas A&M University and member of the 2016 Beef NRC committee presented an excellent overview of the new NRC publication that was released May 16. This was a great opportunity for the members to get a first look at the new publication and Dr. Tedeschi gave an extensive workshop on how to use the new software as well. Discussion included conversation about how the software could be utilized and improved and things the next NRC committee should consider including or expanding upon. Experiment Station Reports continued in the afternoon. Committee administration meeting and plans for 2017- The group decided to hold the meeting in Fargo, ND at North Dakota State University. The group also tentatively planned on Colorado State University for 2018.

SHORT-TERM OUTCOMES

 

General:

 

Again in 2015 members of the NCCC308 committee achieved goals that address nutrition and management issues related to performance, carcass value, and environmental sustainability of beef feedlot operations.  This year, 12 committee members met to discuss novel approaches to integrate individual contributions into a cohesive report that is meaningful to our clientele.  Written station reports were submitted by 10 members (IA, NE, SD, TX, MI, WI, ND, IN, OK, and OH). Our current report demonstrates the overall outcomes, outputs, activities, milestones and impacts as a group.  In addition to committee member participation, our guests included future beef nutritionists (graduate students), Iowa beef extension personnel, and Luis Tedeschi of Texas A&M as an invited speaker to inform the group about the new beef NRC publication. An overarching goal of our group is to maintain the sustainability of the beef feedlot industry, and successful achievement of our committee goals in 2015 supports this outcome.    

 

Objective 1.  Enhance the utilization of C from energy feeds to compete in an energy economy and improve national food security.

 

Ethanol plants are modifying their production to extract more oil, protein and fiber for use in other industries which changes the nutrient content and energy value.  When ethanol and other biofuel byproducts are fed, the particle size or intensity of processing method may be adjusted to improve energy utilization.  Corn stalks and other low quality residues are abundant and new processes or treatments can improve digestibility.  Members from MN, NE, IA, CO, ND, MI and IA contributed to our understanding of diets or methods to improve energy utilization from feedstuffs.

 

Objective 2. To enhance the environmental sustainability of the feedlot industry through conservation and nutrient management.

 

Many of the requirements for mineral concentration determined by the National Research Council were established using feeding and management practices that do not reflect current industry standards. To better understand trace mineral requirements data were presented on the source and concentration in finishing diets and industry trace mineral strategies were compared with the National Research Council standards.  Similarly, mineral composition of beef and Holstein carcasses were reported and compared to current prediction equations.  Methane production from feedlot manure in anaerobic digesters can decrease gaseous losses from feedyards and provide an alternative source of energy.  The amount of soil contamination in the manure appears to have an impact on the production of methane.  Methane production, performance, and volatile fatty acid concentrations were measured in finishing diets using a novel approach.  Endophyte-infected tall fescue can depress cattle growth due to ergot alkaloid-producing endophytes but novel endophyte-infected tall fescue can improve performance.  The mechanism for differences in performance between fescue hybrids is unknown.  Members from NE, CO, and IL presented research related to this objective.

 

Objective 3.  To enhance the production efficiency and quality of feedlot cattle through management strategies and technologies.

 

The impact of vitamin and mineral supplementation was evaluated by four universities (OH, IL, IA, ID) to determine the effects on toxin binding, fetal development and subsequent performance of progeny in the feedlot, antioxidant activity, oxidative stress, and source of trace mineral (organic vs inorganic).  Five universities evaluated different management practices that use beta-agonists, implants, direct fed microbials, and essential oils (MN, NE, IL, WI, IN) to determine optimal management strategies when these products are used.  Grain adaptation, forage concentration in finishing diets, genetic influences on feed efficiency, and slatted floors with rubber mats were also evaluated by members of the committee (ND, MI, IA).

 

Outputs

 

Committee members from 11 states made 55 presentations to stakeholders in state, regional, national or international meetings. The presentations included webinars, cattle producer meetings, and scientific meetings across the US. Findings associated with NCCC308 Objectives were presented. In 2014, members of the committee published 55 refereed journal articles, 20 papers in proceedings, 29 experiment station publications, and 55 abstracts on project objectives. In addition, committee members published 49 articles in trade publications and newsletters. These outputs were communicated to academia, beef producers, feed industries, pharmaceutical industries, and consulting nutritionists and veterinarians.

 

Activities

 

Objective 1.  Enhance the utilization of C from energy feeds to compete in an energy economy and improve national food security.

 

The degree of processing dry-rolled corn and particle size influences finishing performance (Colorado State University), gas production, methane production, and digestibility (North Dakota State University). The University of Nebraska evaluated finishing performance when either steam-flaked corn or dry-rolled corn were fed with de-oiled or full oil distillers grains were fed.  Additional byproduct research was conducted by Iowa State University to determine the use of novel distillers grains that had a portion of the fiber removed during cellulosic ethanol production and algae meal from the production of biodiesel.  The University of Nebraska evaluated the optimum inclusion of de-oiled distillers grains, and the impact of replacing corn grain with corn silage when varying concentrations of wet distillers grains are fed.  The University of Minnesota combined data in a meta-analysis to determine the optimal energy value of wet distillers grains concentration, effect of moisture content, and concentration of oil in the distillers grains.  Crop residues were evaluated as either pelleted corn stover combined with distillers grains at the University of Nebraska.  Residues were also evaluated using alkali treatment and moisture content in a collaborative experiment conducted by the University of Minnesota and University of Illinois.  The type of supplement (meal vs. liquid) was evaluated in backgrounding diets at the University of Illinois.

Objective 2. To enhance the environmental sustainability of the feedlot industry through conservation and nutrient management.

 

Trace mineral concentrations currently fed in commercial feedlots were compared with concentrations suggested by the National Research Council at Colorado State University.  Colorado State University also compared the concentration and source of Zn, Cu, and Mg on finishing performance.  The University of Nebraska determined the mineral composition of beef and Holstein carcasses using serial slaughter data.  The University of Nebraska measured methane emissions, volatile fatty acid concentrations, and performance when fat sources were compared with and without monensin and also methane production from manure with different amounts of soil or ash contamination in anaerobic digesters.

 

Objective 3. To enhance the production efficiency and quality of feedlot cattle through management strategies and technologies.

 

Perdue University and the University of Illinois evaluated the impact of dam mineral supplementation on progeny performance in the feedlot.  New technologies using novel feed ingredients such as direct fed microbials, interleukin-10, algae, clay minerals (saponite), or elevated mineral and vitamin concentrations were fed to determine the impact on performance, meat quality, animal health, temperament, feeding behavior, antioxidant capacity and digestibility in finishing diets by many of the committee members (WI, IN, NDSU, MN, NE, IA, OH).  The University of Wisconsin and University of Nebraska evaluated multiple implant strategies for beef and Holstein fed steers.  Iowa State University continued to evaluate feed efficiency ranking and the potential influence of nutrient digestibility on feed efficiency.  Michigan State University compared slatted floors with floors covered with rubber on lameness, hide cleanliness, and performance. 

 

Milestones

 

The committees milestones are a result from the interaction and collaboration that is generated at our annual meetings in four major areas: 1) determining effective uses of processing or alkali treatment of low quality residues in diets with distillers grains, 2) increasing our understanding of the effects of novel technology or management to improve performance, beef quality and animal welfare, 3) continuing to increase a database that allows us to predict the energy value of byproducts produced using different production methods at the ethanol plant, and 4) determining appropriate mineral concentrations to reduce the impact on the environment. 

 

Because of the interaction at the committee meeting in 2014, the University of Minnesota and Illinois collaborated in a project to determine whether alkali-treatment (CaOH₂) of corn stover or simply adding water to corn stover improved gains and feed efficiency of cattle during a backgrounding phase.  There were no differences in feed efficiency when alkali treatments were fed but the authors reported an increase in average daily gain and intake when water alone was added.  Perdue University reported that addition of calcium oxide at 1% of the diet enhances performance of cattle fed distillers grains.  The University of Nebraska replaced corn with pelleted distillers grains and corn residue and were able to maintain performance in diets with 40% distillers grains.  These results increase our understanding of treating low quality residues and the impact of altering ruminal pH when an alkali treatment is used with distillers grains.

 

Members of the committee continue to develop and test new approaches to improve performance, animal health, and carcass characteristics.  Feeding antibodies, vitamins, minerals with beta agonists, essential oils, direct fed microbials, implants and clay minerals was reported by the University of Wisconsin, Iowa State University, University of Illinois, University of Nebraska, North Dakota State University, University of Wisconsin and Perdue University (respectively).  These results suggest some products have an impact on economically important traits or metabolites. 

 

Data reported by Iowa State University, the University of Minnesota, Perdue University, and the University of Nebraska increase our understanding of the energy value of byproducts that have oil removed, byproducts that undergo a secondary cellulosic ethanol fermentation, and algae byproducts from oil production as a feed ingredient.  As the database for feeding de-oiled distillers grains continues to grow, we have determined that removing a portion of the corn oil reduces the energy content of the diet.  The concentration of oil in the distillers, corn processing method, and inclusion level of distillers grains all have an impact on animal performance.  Iowa State University reported on novel distillers grains that were fermented for cellulosic ethanol production and reported a decrease in energy value compared with traditional distillers grains.  The Iowa State University also determined the use of algae as an energy source is feasible but reports from Perdue University suggest it may decrease shelf life of retail product.  Colorado State University and North Dakota State University reported that in diets containing distillers grains particle size does not have an impact on performance or gas production (respectively).

 

Colorado State University and Ohio State University evaluated the source and concentration of trace minerals and compared concentrations fed in the industry with the National Research Council recommendations.  These experiments did not demonstrate a difference in performance when the source or concentration was changed suggesting additional supplementation of certain minerals is not warranted.  The University of Nebraska used samples from serial slaughter experiments to determine carcass mineral retention in beef and Holstein cattle.  When mineral retention was expressed as g/100 g protein gain, the results suggested current NRC predictions are accurate.
