Brief Summary of Minutes of Annual Meeting

Call to order and introductions: Chair David Beede called the meeting to order at 1:15 p.m. He asked attendees to introduce themselves and reviewed the agenda. Agenda is attached to meeting minutes. Mike Schutz and Tamilee Nennich, local hosts, welcomed the group to Indiana and explained plans for dinner and the farm tour on Saturday.

Washington update: Charlotte Kirk-Baer; USDA/CREES advisor for NC-1042 addressed several topics regarding the reorganization of USDA and impacts of the new Farm Bill. The budget for CSREES will continue until March 2009. Changes in farm bill specify reorganization within USDA to create a Research Education and Extension office with an Undersecretary of Agriculture (6 divisions). The Under secretary of REE will be a USDA chief scientist. A National Institute of Food and Agriculture will replace CSREES by Oct 2009. It will establish an Agricultural and Food Research Initiative that combines NRI and Initiative for future agriculture and food systems. Secretary must prepare a roadmap for agricultural research, extension and education. NIFA will have new funding for specialty crops, organic, and beginning farmer and rancher programs (for extension). Funding will be 60% fundamental: 40% applied research and multi-institutional grants will be important. Integrated grant proposals will look closely at extension role in terms of involvement and budgeting. Strong extension components will get extra emphasis.

David Beede added at the end of the Washington update that MSU has done a dairy survey that gave producer information relevant to this discussion (http://www.mdr.msu.edu).

Administrative advisor report: Dave Benfield: Stakeholder input is very important. The new NRI will have more flexible programs  more emphasis on integrated and applied projects. There will still be 406 programs with earmarks for states. Difference now is that those programs will become competitive. Could change some state programs. Adding a leverage section for annual reports will help show impact. Papers that are collaborative between stations needed to be highlighted. Cross disciple funding is very important.

2009 Oversea Meeting Plans  Lisa Holden reported for the planning committee on their finding for an overseas meeting in 2009 or 2010. The on-line member survey had 18 total responses with 11 negative 7 positive; of the positive Netherlands, France, Spain, Italy, and UK were listed as locations of interest. Several options were considered in terms of cost and it was determined that a minimum of $2000+ per person would be needed. Some trips were over $3000 per person. The consensus was to not try an overseas trip in 2009, but maybe 2010.

Station reports: Dave Beede asked members to present their state project reports with a limit of 10 minutes per station. States were asked to report in the same order as the project objectives. Stations reporting on Thursday afternoon were: Objective 1: MN, NH, Purdue, PA, Objective 2: PA, MD, Purdue, NH, SD.

The group had an excellent dinner at the Lafayette Brewing Company.

Friday, October 17, 2008

Welcome by: Marshall Martin, Asst. to Director of Agricultural Research programs, Purdue University.

Station reports: Objective 2: NE, MI, CA, FL, Objective 3: PA, VA, FL, GA, UT, WI.

12:20 p.m.: Invited speaker  Dr. Susan Eicher with USDA Livestock Behavior Research unit (Purdue) reported on the different research projects being conducted at their facility and possible areas of collaboration.

1:15 a.m.: Members were asked about plans for future work. Areas listed were: energy use by a dairy  conventional vs organic; heifer raising  benchmarking; coproducts  environmental twist; new and beginning farmer plus small and medium farms; nutrition vs greenhouse gases (cuts across areas but more on the manure side); distillers grains and methane production; imaging to determine body condition of cows, heifers/deaths/size; sustainability of a dairy; and lameness/environment/cow comfort.

1:30 p.m.  The committee was divided into two groups with the charge to come up with a concept for future work/grants to come from NC-1042. The general concept developed by each group is given below.

Group 1 Title: Strategies for Sustaining Multi-generational Family Farms: Developing Internal Herd Growth.

Hypothesis: Sustainability of the family farm depends on the ability to growth herd numbers in order to incorporate the next generation into the business.

Objectives: To develop decision systems to support viability of multi-generation family farms through nutrition and management decisions that enhance internal herd growth such as: a. utilize heifer database data to predict herd performance; b. projection of cow numbers (culling rates, use of sexed semen, heifer); c. profitability indicators for growth and production (from birth of calves through calving); d. common tools to be presented in multiple states through extension education; and e. need to incorporate expertise in family decision making (maybe someone from NE 177).

Group 2: Title: Long-term Sustainability of Dairy Farm Systems in the United States Objectives: 1) assess management strategies that concurrently optimize resource use efficiency and environmental quality, and 2) encourage adoption of multifunctional management strategies to promote long-term dairy farm sustainability in the U.S.

Research Objectives: 1) Identify, understand, quantify, and characterize dairy farm systems and their interrelated ecosystem services and community interactions; 2) Define, conceptualize, and represent dairy farm agroecosystems into innovative empirical predictive computer models that include farm biophysical production systems, environmental impacts, ecological services, and social and economic indicators; 3) Collect, analyze, and parameterize field observations to calibrate and validate models. 4) Integrate stochastic analysis and portfolio theory to develop agroecosystem indicators to assess dairy farm long-term sustainability.

Extension Objectives: 1) Encourage, engage, and involve key stakeholders to participate in project inception, development, and implementation through a participatory systems model approach; 2) Promote extensive dissemination of multifunctional management strategies through eXtension, and Cooperative Extension channels; 3) Promote innovative incentive programs to dairy farm managers adopt multifunctional management strategies; and 4) Prepare six one-day workshops in each one of the involved locations to (i) educate dairy producers and other pertinent stakeholders on multifunctional management strategies of dairy agroecosystems sustainability and to (ii) evaluate project effectiveness by assessing changes in knowledge, attitude, management, and adoption practices; document success histories; and propose continuation of work. The focus will be on long-term effect.

Business Meeting David Beede called the Business meeting to order at 3:30 p.m. Minutes of the 2007 NC-1119 meeting were approved as written. He made a few comments relative to the ending of NC1119 and its final report. Due to limited space, the final report had to be pared down considerably. If anyone wants to read the report they can go to the NIMSS site. A vote of thanks was given to Dave for his efforts in putting together the final report.

Location and date for 2009 meeting: As stated earlier, Lisa Holden reported for the planning committee on options and costs to have the 2009 meeting in Europe. Based on the survey taken of the members, the 2009 will not be held in Europe, but will try for 2010. After discussion on alternate sites, a motion to go to British Columbia for the 2009 meeting was put forward. The motion was approved. Paul Kononoff will make the initial contacts and Steve Berry, and Allen Young will help make any additional arrangements for the meeting. The tentative date was set for ~Oct. 15, 16, 17, 2009. It was suggested to maybe start on Thursday morning to allow more free time to sight-see.

Website and Historian report: Mike McGilliard reported that the historian report needs to be updated and will be done soon. He also reported that the NC1042 website has been updated by adding links to spreadsheets developed by VA and PA members. He also stated that if anyone has other links they want put on this site, let him know.

Publications and symposia report  Hugh Chester-Jones reported that this group has been involved with symposiums at the Midwest Dairy Sectional meeting. He also suggested that there may be a possibility to write a journal article on some topic for the meeting (possibly a literature review). He suggested that the group develop a symposium for the Midwest meeting of March 2010 with the idea ready by August 15, 2009. The Long-term Sustainability of Dairy Ecosystems group will go first and the other group will go the next year.

Election of Secretary for 2008-09  Ken Kalscheur moved to nominate Paul Kononoff as secretary for 2008-2009. Motion approved. Committee confirmed that Allen Young is the new chair for the 2009 meeting.

Other business: It was moved to thank both Mike Schutz and Tamilee Nennich for hosting an excellent meeting. In addition a motion was made to thank David Beede for chairing this years NC-1042 meeting. Both motions were seconded and approved enthusiastically.

Meeting was adjourned by 4:30 p.m.

The group had an excellent meal at Brunos in West Lafayette.

October 18, 2008 (Saturday): Farm Tours

7:00 a.m.: Depart for tour.

The group visited the Purdue Dairy, Forgey and Foergs Riverview Dairy (pasture-based), Sam and Pam Jones Robotic Dairy, and Fair Oaks Dairy. All dairies were very interesting, making for an enjoyable tour.

Returned to Lafayette at around 4:00 p.m. EDT.

A series of projects on feeding calves were conducted by MN. A limited feeding study with young heifers did not improve feed efficiency, but offered acceptable growth and body weight gain. Another study to reduce milk replacer (MR) feeding rate and/or the number of MR feedings resulted in similar performance and health compared to the control calves. Calves fed MR supplemented with animal plasma and nutritional additives APL showed similar performance and health to calves fed all milk protein milk replacers. Another study looked at including a rumen fermentation enhancer in the grain mix did not improve heifer performance. Another looked at the form of corn in the calf starter (CS) or milk feeding schedule. Once a-day milk feeding did not change CS intake as was anticipated. Also delaying socialization for 14 d resulted in similar growth as compared to calves grouped housed for 112 d. Finally, feeding a MR containing organic trace minerals with or without organic Se did not affect pre- and immediate post weaning calf performance and health compared to calves fed MR with inorganic trace minerals.

Researchers from VA and PA have developed a computer spreadsheet for dairy farm managers to determine cost-effective methods of feeding milk diets to calves during their first two months of life. The spreadsheet takes individualized farm costs and produces comparison charts. Sensitivity of the recommendations can be tested for rapidly rising or declining energy and feed costs. The decision is influenced significantly by herd size, with large herds more capable of spreading pasteurizer investment costs over more calves. Small family farms, for instance could save $5,000 per year pasteurizing waste milk for half their calves, whereas farms ten times as large could save 20 times that amount.

Studies were conducted at NH on addition of sodium bicarbonate to colostrum replacer fed to calves of dams fed anionic salts. Data is currently being analyzed.

A study was conducted in LA to determine effects of differing fat and protein levels in commercial milk replacers on the growth performance and rumen development of neonatal Holstein calves. These data indicate that increasing the dietary protein content of milk replacer without reducing fat content improved growth in young dairy calves without compromising health or rumen development. Another study was conducted to determine the effects of probiotics and yeast culture on rumen development and growth of neonatal Holstein dairy calves. Calves consuming feed containing P had an increase in acetate, with females showing a greater increase over males. Incorporating YC into starter may result in an increase in growth. However, this effect did not continue after weaning. Rumen development remains unaffected by the addition of YC and P to grain diets.

Work was continued at IN on the physiological impact of stress on dairy calves. Cortisol levels and other indicators of stress were evaluated in calves undergoing stress brought on by alternating isolation and mixing into novel groups on subsequent days for 10 days. Molasses intake, as a putative indicator of stress, was measured along with fecal samples for culturing of gut microflora and jugular blood samples to assess presence of stress hormones. Laboratory analysis and statistical association of stress with the various indicators continues. Other projects such as evaluating bedding substrates for calves in hutches in Midwest summer conditions and diets Dry Distillers Grains with Solubles (DDGS), and two diets with different inclusion rates of de-oiled DDGS are on-going.

Several studies were conducted in PA that pasteurization reduced the bacteria counts of waste milk. However, 2 farms did not reduce the bacterial population in approximately 50% of the samples, suggesting that incomplete pasteurization may be a common problem and monitoring pasteurizer performance is an important step in assuring the quality of waste milk after pasteurization. Other studies found that differences in N utilization between high concentrate (HC) and high forage (HF) diets were small and not evident until nitrogen intake increased to impractical levels. Also, feeding different ratios of forage to concentrate did not change total viable bacteria population.

Objective 2: To optimize lactating and dry cow decision-making as it relates to animal health, nutrient utilization, milk production, reproduction, and profitability (cows)

A computer program that calculates projected cash flows for individual dairy cows and optimizes breeding and replacement decisions was developed at FL. The program idea fits within the idea of precision agriculture, where management is fine-tuned based on individual cow performance. The program is also used to evaluate the profitability of crossbred vs. purebred cows. Other NC-1042 related projects focus on analysis of culling in DHIA records and economics of pregnancy diagnosis and sexed semen.

Research on the effects of feed sorting on chewing behavior, production, and rumen fermentation in lactating dairy cows was conducted in PA. Despite drastic differences in particle size between diets, there were no changes in chewing behavior, production, and rumen fermentation found in this study.

Several experiments were conducted in IN to determine the effectiveness of co-ensiling wet distillers grains with solubles (WDGS). When haycrop forage was direct cut, ensiled and mixed with WDGS at feeding, the cows ate less feed and produced significantly less milk than when the same silage was co-ensiled with WDGS. In addition, several studies have been undertaken to evaluate automatic recording of reticular temperatures of dairy cows. Care must be taken to ensure cows have not consumed large amounts of water before recording of reticular temperatures. The use of image identification for the assessment of body condition is being conducted. Also, an automated activity monitoring sensor was utilized in a study to examine various management factors affecting lying behavior of confined Holstein-Friesian dairy cows. Production level, time from most recent calving, day, and week were significant predictors of lying time, day, and week impacted the number of lying bouts.

Ohio research looked at the effects of daily variation in dietary protein concentration on milk production in mid-lactation cows. Variation in daily dietary CP content does not affect milk production in mid lactation if the cycle of variation is over a period of two days. Their findings have two important consequences. First, unless we can quantify the response to supply variation, it is impossible to design an economically efficient feed quality control program at the farm. Second, standard nutrient requirements tables are of little value in predicting the effect of variation in daily supplies. Researchers in CA studied lameness in dairy cows. Monthly lesion specific incidence reports of participating dairies are given to the dairy producer and claw trimmer. These are used to monitor claw health and make management decisions regarding preventative programs. A database is currently being analyzed for incidence rates and type of problem.

Several experiments were conducted by NE looking at effects of feeding distillers grains. They found that rations can be balanced for dairy cattle to include up to 25% DM WDGS and increase milk production and protein, maintain nutrient digestibility, and reduce nitrogen excretion. Also, inclusion of HPDDG at 20 % DM may increase milk production and efficiency without negatively affecting component concentration. Analytic methods for evaluating corn (co)products were developed as well as a measurement of to quantify the production of ruminal bacteria; which may enable us to measure the ruminally undegradable protein.

Work in MD has focused on building a system to continuously monitor body temperature (BT) within the vagina of postpartum cows. With correction factors, efficiency for detecting fever increased to 65%.

Two research areas were reported by MI. In the first, inclusion of distillers grains reduces unadjusted and fat-corrected milk yield but not milk fat percentage in more fermentable diets. Positive response of FCM to DG inclusion is greatest when overall diet fermentability is limited. In contrast, in more fermentable diets inclusion of DG reduced milk yield. In the second, feeding coconut oil at 5% of the dry matter in a high starch diet to lactating dairy cows had dramatic negative effects on feed intake and milk yield, reducing intake by 39% by 3 days after introducing coconut oil in the basal diet. We conclude that the 5% feeding rate is too much for practical feeding.

Wisconsin reported developing several different decision tools. The first was a "prototype" decision support system to assess the income over feed cost and the optimal utilization of corn grain for entire lactations diets. Preliminary results support largely the opportunity to decrease corn grain in the diet and increase the use of forage and grazing practices to improve net income over feed costs under multiple farm and current market situations. The next was a tool to compare lactation curves to Wisconsin benchmark lactation curves according to defined herd rolling herd average (RHA) and parity. The last is a decision tree tool to evaluate the economics of early post-partum mastitis test and treatment. This is still in the developmental stage.

Minnesota is conducting research on the comparison of cross-ventilated freestall barns and compost bedded pack barns with naturally ventilated freestall barns. Incidence of lameness and alternative bedding materials are being considered. Data is being collected.

South Dakota also reported work with de-oiled dried distillers grains with solubles. They found that the efficiency of N utilization for milk protein synthesis was not affected by including dDGS up to 30%. Also non-forage fiber from DG can partially substitute for starch from corn in dairy cow diets without affecting milk production and milk composition.

Researchers in New Hampshire evaluated in vitro methods to estimate digestibility of amino acids in the RUP fraction of blood meal and found that the guanidination method does not appear to be adequate to predict intestinal digestibility of Lys or RUP-Lys in BM samples. They also found that by treating wet brewers grain with a silage inoculant could increase shelf life increasing the opportunity for smaller dairy producers to feed a product that otherwise would be difficult due to spoilage.

Objective 3: To evaluate system components and integration of information into decision-support tools and whole farm analyses to improve efficiency, control variation, and enhance profitability, and environmental sustainability (whole farm)

Several studies from WI were reported. A whole farm simulation model for dairy farm expansion is in the process of being developed as well as a tool to evaluate (i) the convenience of Livestock Gross Margin insurance product over traditional milk puts and feed calls and (ii) the opportunity of using seasonal climate predictions to better hedge. Work has also begun on studies to measure the impact of six major dairy herd diseases to the income over feed costs (IOFC). In addition, energy and environmental impact will be used to create a model to quantify the energy intensity and environmental impacts of integrating bio-fuels production systems, new technologies and management practices on the energy, green-house-gas (GHG) and nutrient balance of individual farms. The Dairy Business Analysis Project (DBAP) has been continued with FL and GA where complete financial and production data are maintained for participating dairies and available for analysis. DBAP reports are often requested by dairies that try to secure loans and other people interested in the financial performance of Florida dairies, such as CPAs, lenders, and investors. DBAP data is also used in reports that describe the financial feasibility of environmental regulations proposed by the Florida Legislature.

Researchers from IN have developed a stochastic simulation model to assess the potential economic benefits associated with investments in precision dairy farming technologies, such as temperature monitoring or automatic body condition score (BCS). Preliminary results revealed that estrus detection and change in estrus detection rates are far and away the most important determinants of the decision to invest in an automatic temperature monitoring system and those assumptions about the desired changes in managing BCS are crucial to long term benefits of investing in an automatic BCS system. The efficacy of storing WDGS with corn or hay crop silage before ensiling provides an opportunity for small or medium-sized dairy farms to utilize WDGS in their feeding and feed cost control strategies. Large farms are able to better utilize WDGS because they can feed the product quickly and before spoilage may occur. Farms unable to utilize an entire load of WDGS quickly will benefit from alternative storage opportunities without negative consequences on dairy cattle performance.

Work at UT collected production and continuous environmental data from commercial dairies. A high correlation in temperature was found between sites. However, average humidity percent may be more variable than temperature and can alter several measures under the summer conditions. Also breed effects need to be considered as evidences by the differences between variables for Jersey and Holstein herds.
