Minutes from the Symposium committee conference calls from June 27, 2002, September 24, 2002 were summarized. The onsite participants prepared a draft agenda for the symposium and it was emailed to the conference call participants. During the conference call the dates (November 4-5, 2003), location (Kansas City Airport Marriott in conjunction with the AFIA Nutrition Council Meeting), and agenda for the conference were prepared. Subsequent Symposium committee conference calls will be held December 5, 2002 and January 14, 2003.
After the conference call, station reports were presented and discussed from CA, IA, ND, WA, and WI. Executive committee for WCC-203 for 2003 will be Marc Bauer, Chairman, and Lou Armentino, vice chairman and Secretary. The 2003 meeting will be held in conjunction with the Symposium on November 4-5, 2003 at Kansas City. Meeting adjourned at 11:30 am November 15, 2002.

Accomplishments

1. Quantify the production, use, environmental impacts, and economic value of products from the processing of agricultural commodities.

Most of the reported work under this objective related to economic value and animal performance when fed byproduct feeds and on environmental impact as described below and on determining maximum and optimum inclusion rates in diets of farm animals.

Marketing studies were conducted at N. Dakota and production of numerous byproducts was reported for California for a 10-year time frame. Comparison of US production of byproducts to international production was reported (California).

Feeding byproduct feeds has important beneficial environmental impacts because the byproducts are diverted from being a burden to the environment as landfill or direct land application and are instead utilized as useful animal feeds. In addition, these byproduct feeds may have characteristics that also produce a beneficial environmental impact at the farm level. Methane is a greenhouse gas produced on livestock farms. Production occurs in the ruminant animal and also during the anaerobic storage of animal waste. Reducing animal methanogensis has beneficial effects in reducing greenhouse gas emissions and in improving the energetic efficiency of converting feed to animal products. Tallow, a byproduct of the meat processing industry, and yellow grease, a byproduct of the restaurant industry, were shown to reduce methanogenesis from 157 to 98 l/animal/day in cows fed a grass hay diet (Washington State University). In addition, a preliminary patent application has been filed on a byproduct extract that has anti-methanogenic properties (WSU).

Ammonia emission from livestock units is a cause for concern in air and water quality. Ruminant animals can secrete waste N in the form of urine urea or fecal N. Fecal N is less likely to contribute to ammonia loss and more likely to be incorporated into plant growth. A study was conducted to measure the effect of delivering digestible carbohydrate to the lower intestine to divert blood urea N into feces and away from urine via enhanced lower gut fermentation. In this experiment, abomasal infusions of pectin were used to enhance lower gut fermentation (U. Wisconsin). Although pectin is not itself a significant byproduct feed, many high fiber byproduct feeds are likely to enhance lower gut fermentation because they contain fermentable fiber and they are small enough to pass rapidly from the rumen thereby providing increased carbohydrate substrate to the lower intestine. Results of this trial suggested that the strategy might work. There were trends for a shift in N from urine to feces. The trial was underpowered due to the loss of one of four cows and nitrogen balance measures were confounded by a reduced feed and N intake in the pectin treatment. The trial will be replicated in the future to better gauge the size and significance of the effect.

Wet milling of corn is an established method for fractionating corn into various food, feed and fuel products. A new wet corn-milling product was fed to thirty lactating Holsteins. Feeding 40% of this byproduct in the diet (replacing both concentrate and forage) improved efficiency of milk production in comparison to diets not containing byproducts (U. Nebraska). Use of corn and sorghum in a dry milling process for ethanol production is a growing industry in the U.S. A study compared feeding these materials wet or dry at 15% of the diet in lactating cows and also compared wet sorghum or wet corn distillers grains fed at 30% of ration DM to steers. Performance was superior to non-byproduct diets in steers, with corn and sorghum byproduct found equal to each other. Efficiency of milk production in lactating cows was similar across the different byproducts fed (U. Nebraska). Wet corn gluten feed at 18.5% of diet DM was predicted to give the best lactation performance in similar trials at North Dakota.

Byproduct feeds provide neutral detergent fiber in a physically reduced form. Corn gluten feed (wet milling byproduct) fiber was found to be 74% as effective as alfalfa fiber for maintaining fat test but only 11% as good at providing beneficial physical characteristics to the diet. Corn gluten feed was also shown to be an effective forage replacement for dairy heifers.

Feeding systems can have an impact on using byproduct feeds and often these feeds are limited to total mixed ration strategies. Research with 102 crossbred beef heifer showed that wheat middlings could be self fed and produce equal response to a mixed ration. These results would allow wheat middlings to be fed in more extensive, low cost operations that lack feed mixing equipment (N. Dakota). Feed storage is critical in use of wet byproducts. Wet corn gluten feed could be co-ensiled with whole plant corn (U. Nebraska). Methods to improved ensiling of wet beet pulp using dry byproduct adjuncts showed that 35% DM provided the best ensiling and that addition of urea was also beneficial (N. Dakota).

Forage level and physical form can interact with byproduct and other concentrate feeds. Studies at U. Nebraska showed inclusion of alfalfa hay improved the utilization of NDF from Corn Gluten Feed. In order to remove passage effects in these types of interactions, five byproduct feeds (beet pulp, soy hulls, wheat middlings, corn gluten feed and soybean hulls) were incubated with different forages and compared to barley and corn grain. Barley and corn were expected to decrease OM digestion relative to byproduct feeds but this did not occur (N. Dakota). Four ruminally and duodenally cannulated steers were used to test the effect of alfalfa or corn stover on use of concentrated separator by-product. Concentrated separator byproduct improved the ruminal and total tract N digestibility with stover more than it did with alfalfa (N. Dakota).

2. Improve the assessment of the nutritional value of by-products.

Measurement of animal methane production is a costly procedure. A low cost means to evaluate the effect of byproduct feeds on ruminal methanogenesis would greatly improve the ability to estimate the economic and environmental impacts of feeding different byproducts. Efforts were made to correlate two more easily measured ruminal parameters (fluorescence of F420, a key methanogenic enzyme, and concentration of Coenzyme M) with actual methane production. Results with F420 were not deemed useful or reliable but Coenzyme M may be a useful indicator of a byproduct (or other feeds) impact on ruminal methanogenesis (WSU).
Workers at U. Nebraska applied the techniques developed for comprehensive fiber analysis by the Florida station to evaluate 23 feeds commonly fed in the Midwest. The resulting analysis is an important improvement in developing strategies to best use these feeds and to explain the performance obtained in feeding trials.

3. Disseminate information on the use of by-products.

As per minutes of meeting and conference call, planning for the Third National Alternative Feeds Conference was conducted. The conference will be held Nov 4 and 5, 2003 at the Kansas City Marriott in conjunction with the AFIA Nutrition Council Meeting. Symposium agenda is attached.
