The 2011 meeting of the NCCC-208 Committee was hosted by South Dakota State University on May 24 26th, 2011. Prior to the meeting an agenda was circulated and travel arrangements made my attending members.
On the afternoon of May 24th, Ben Holland met Casey Maxwell and Kendall Swanson in Brookings and travelled to the Opportunities Farm, near Lennox. They picked up Steve Loerch, Tara Felix, Jon Schoonmaker, and Steve Rust at the airport in Sioux Falls en route to the farm. At the Opportunities farm they were met by Dan Loy, Stephanie Hansen, Mary Drewnoski, Alfredo DiCostanzo, and Jeff Jaderburg. The Opportunities Farm manager, Matt Loewe, and Ben Holland guided a tour of the farm. The group traveled to Mad Marys steakhouse in Flandreau, SD for supper. There John Mrozinski presented data from his Masters Thesis on economics of operating facilities at the Opportunities Farm and Ben Holland presented a cattle performance summary of the farm.
On the morning of May 25th, the group traveled to Redstone Feeders near DeSmet, SD and visited with Bill and Todd Wilkinson regarding their operation and facilities. Following the tour, they returned to the SDSU Animal Science Complex in Brookings where John Lawrence joined by video conference. Dr. Lawrence discussed current situations in USDA regarding the percent of federal dollars required to be used for multi-state and integrated programs. He also discussed progress on the 2012 Farm Bill, and changes on programming priorities, citing the pull back on the NIFA-AFRI climate change request for applications.
The committee underwent a midterm review in 2010, and was successful. Dr. Lawrence stressed the importance of the committee documenting collaborative and coordinated efforts in its station reports and suggested an executive summary under each committee objective, followed by short-term outcomes, etc. After the video conference ended, it was suggested by Steve Loerch that Jon Schoonmaker assist Ben Holland in developing a format for the 2011 and future reports. A question was raised as to what activities were. The 2012 meeting was set to be held at Purdue University, and Jon Schoonmaker will be secretary. A suggested site for the 2013 meeting is the University of Minnesota. Following the business meeting, lunch was served the SDSU graduate students.
After lunch, the group toured the feedlot at the SDSU Ruminant Nutrition Center and metabolism facilities in the Animal Science Complex discussing research methods and capabilities. Station reports were then held until the meeting was adjourned for supper and discussion at 6:00 pm.
The meeting resumed at 8:00 am on May 26th when Steve Smith joined by telephone to give a report on personnel changes and funding opportunities within NIFA. He pointed out the broad spectrum of the recent requests for applications for the foundational programs and indicated RFAs would be coming soon in other program areas. He encouraged members to closely read RFAs in order to find appropriate programs to apply to. He also encouraged soliciting and submitting stakeholder input, and encouraged members to contact him with further questions. Station reports were resumed at 8:45 am and were concluded at 10:45 am. Dr. Aimee Lutz presented some of her work on the hormonal regulation of feed intake and composition of gain in growing cattle. The meeting adjourned at 11:30 am.
Section A: Short term outcomes
Objective 1. To enhance the utilization of alternative feedstuffs including those which are available as a result of increased biofuel production while reducing reliance on cereal grains.
Iowa State University
Producers may be able to feed greater amounts of dietary sulfur than previously recommended by the NRC when sufficient levels of roughage are included in the diet.
Wet or modified distillers grains can be stored successfully for long periods with minimal costs and 7-12% storage losses.
Calcium oxide-treated stover may be fed at up to 20% of the diet dry matter along with modified distillers grains as a partial replacement for corn grain in feedlot diets without adversely affecting daily bodyweight gains or feed efficiency.
University of Minnesota
Conventional distillers grains and low-fat distillers grains, at 35% inclusion, can be fed in place of dry rolled corn without affecting live performance or carcass characteristics. Both distillers grains treatments led to increased PUFA compared with the dry-rolled corn control. Low-fat distillers grains may lead to greater lipid oxidation compared with a dry-rolled corn control or a traditional distillers grains-containing diet.
Increasing the dietary S concentration from 0.25 to 0.50% led to a reduction in DMI and ADG, but did not affect feed efficiency. Low sulfur steers had greater marbling scores and 12th rib backfat, and had a higher percentage of USDA Choice-grading carcasses than high sulfur steers.
Substrate S concentration did not affect final pH of incubations. Total gas production increased with increasing starch concentrations. Total H2S release was affected by starch concentration, but not by sulfur concentration.
Increasing dietary S concentration generally increased H2S gas concentration. Distillers grains inclusion and increasing roughage inclusion generally increased culture pH.
Inclusion of a Saccharomyces cerevisiae fermentation product did not affect DMI or ADG. Inclusion of a Saccharomyces cerevisiae fermentation did not affect marbling, LM area, or backfat thickness.
The Ohio State University
Sulfuric acid in DDGS and not organic acid production may be responsible for the low rumen pH observed and may influence the maximum inclusion of DDGS in cattle diets.
Monensin supplementation decreased H2S concentration and may decrease the risk of polioencephalomalacia for cattle fed high DDGS diets.
Cattle fed 60% DDGS diets benefitted from increased dietary forage and the effects of monensin and forage were additive for ADG and HCW.
Despite the lack of starch in DDGS, propionate concentrations increased with increasing dietary DDGS. Low rumen pH contributes to increased production of H2S, alters rumen VFAs, and creates a hostile environment for fiber fermentation. Thus, the low rumen pH resulting from the sulfuric acid present in DDGS may be a primary cause for reduced intake, growth rate, and increased incidence of PEM when high dietary levels of DDGS are fed.
Rumen concentrations of acetate (A), propionate (P), and A:P were not affected by monensin supplementation. Contrary to some in vitro data, our study suggests that monensin does not increase the risk of S-induced PEM when cattle are fed 60% DDGS diets.
Daily urine output increased linearly with increasing dietary inclusion of DDGS. Urine pH decreased linearly with increasing dietary DDGS. These data suggest urine is a major route for excretion of acid when high S diets containing DDGS are fed.
Oklahoma State University
Feedlot performance was drastically decreased for cattle fed a WDGS transition ration compared to a traditional ration. There were no effects of transition method (two-ration blend vs. traditional) on feedlot performance.
Purdue University
Gestating heifers fed forage supplemented with distillers grains (DG) produced progeny with increased birth and feedlot entry weights compared to gestating heifers fed corn silage.Milk production was not different, but milk from DG supplemented heifers contained elevated long-chain fatty acids, PUFA, CLA, and milk urea nitrogen. In addition, milk from DG supplemented heifers had lower concentrations of short-chain and saturated fatty acids than from heifers not fed DG. Feedlot performance of progeny was not affected by gestation supplementation. However, steers from heifers fed DG had greater dressing percentage than steers from non-supplemented heifers.
Diets containing 0, 30, or 60% DDGS fed during the early feeding period (d 1 99) to early weaned (134 d of age) steers did not impact finishing performance. However, dressing percentage, HCW, fat thickness, rib-eye area, and %KPH were affected quadradically by DDGS level, increasing from 0 to 30% DDGS and decreasing from 30-60% DDGS.
South Dakota State University
Performance by yearling steers fed 40% by-product finishing diets was used to estimate relative energy content of evolving by-products of ethanol production. The diets were based on DRC. The DRC was assumed to contain 100 Mcal/cwt NEM and 68 Mcal/cwt NEG. By-products, their EE and glycerol content, and estimated NEG were: WCGF-DDGS blend (Golden Synergy) 8.2% EE, 6.8% glycerol, 65.8 Mcal NEG; WDG (w/o syrup) 8.9% EE, 4.2% glycerol, 71.5 Mcal NEG; and WDGS 12.2% EE, 8.0% glycerol, and 78.1 Mcal NEG.
Finishing steers fed dry-rolled corn-based finishing diets with supplemental nitrogen from soybean meal (SBM), slow release non-protein nitrogen (SRN, Optigen, Alltech Inc., Nicholasville, KY), or SBM and OPT had similar finishing performance and carcass characteristics.
Cover crops including a mixture of turnips, radishes, lentils, oats, and millet provided a suitable pasture for grazing weaned calves for 45-d when supplemented with a DDGS-based supplement. However, ADG was less for steers on pasture (1.56 lb/d) than on a corn-based backgrounding diet (2.90 lb/d). After all calves were placed on similar backgrounding diets for 45 additional days, cover-crop calves had superior ADG and feed efficiency, resulting in a less expensive backgrounding system overall.
Utah State University
Steers grazing tall fescue, with or without N fertilizer, had higher concentrations of C18:3 cis-9, cis-12, cis-15 and C18:2 cis-9, trans-11 fatty acids (FA) in subcutaneous fat compared with those fed a high-concentrate barley-based feedlot diet (0.41 vs. 0.20 and 0.48 vs. 0.25 g/100 g FA, respectively; P < 0.01). However, steers in the feedlot had higher concentrations of C18:1 cis-9 and C18:1 cis-11 FA than grazing steers. Nitrogen fertilization of tall fescue had minor impacts on the fatty acid composition of subcutaneous fat.
University of Wisconsin
Feed efficiency was improved for steers fed 40 vs.20% inclusion of dried distillers grains (DDGS) and for steers fed chopped hay versus corn silage in feedlot finishing diets, whereas DDGS inclusion level and fiber type did not affect carcass cutability characteristics.
Objective 2. To enhance quality and safety of beef through emerging pre-harvest technologies and management strategies.
University of Minnesota
Neither soy glycerin nor corn processing method stimulated E.coli O157:H7 shedding. Within 20 days of treatment initiation, all calves, regardless of treatment, were basically devoid of E. coli shedding.
At day 14 of sampling, no E. coli O157 was present in any cattle, regardless of treatment.
Modified distillers grains inclusion at 30% of dietary DM increased DMI and tended to decrease feed efficiency compared with no distillers grains inclusion, and led to 13% lower iterated dietary ME values compared with diets without distillers grains. Inclusion of soy glycerin at 10% of dietary DM did not affect any live performance or carcass measurements.
In three Minnesota feedlots, overall E. coli O157:H7 prevalence measured 4.15%, and ranged from 1.03 to 6.38%. Dietary distillers grains inclusion of greater than 25% did not result in increased E. coli O157:H7 shedding compared with dietary distillers grains inclusion of less than 25%.
Overall prevalence of E. coli O157:H7 was 11.7% at a Minnesota fed cattle packing plant.
E. coli O157:H7 probability was lower when cattle were fed distillers compared to those not fed distillers grains. Prevalence of E. coli O157:H7 tended to be lower in winter compared to spring and fall.
The Ohio State University
Gestational energy source did not affect feedlot performance or carcass traits of progeny; however, it did affect glucose clearance rate and initial insulin response. Days on feed increased insulin resistance and decreased glucose tolerance when cattle were fed a high-grain diet.
Purdue University
Supplemental vitamin D (0.25 x 106 IU for 165 d or 5.0 x 106 IU for 10 d) did not improve tenderness in cattle fed 0 or 8.3 mg/kg zilpaterol hydrochloride (Zilmax). Short-term vitamin D supplementation resulted in lower HCW, less 12th-rib fat thickness, and smaller longissimus muscle area than long-term vitamin D. Zilmax increased final BW and HCW.
Neither dietary beta-carotene inclusion nor source of beta-carotene affected feedlot performance or marbling scores of finishing steers and heifers. Synthetic B-carotene (1x, 5x, or 10x NRC requirements) increased longissimus muscle area linearly.
South Dakota State University
Steers were identified as having CC, CT, or TT single nucleotide polymorphisms of the leptin gene. During backgrounding (720 to 950 lb) steers were fed to allow 2.5 or 2.9 lb ADG. A common finishing diet and common harvest endpoint (0.47 in. ribfat) followed backgrounding. When marbling was expressed relative to total carcass fatness, the CC genotype resulted in lower (P < 0.06) marbling than the TT genotype, regardless of backgrounding management. The CT genotype expressed marbling similar to the CC genotype if backgrounded at the lower ADG, but marbled similar to the TT genotype if backgrounded at the higher ADG (interaction P = 0.12).
Plasma ghrelin and leptin concentrations increased for cattle fed a high-grain diet from weaning to finish as they became increasingly fatter. However, cattle initially fed a high-forage diet had similar plasma leptin concentrations but low plasma ghrelin concentrations at a similar subcutaneous fat thickness. Abundance of growth hormone secreteagogue receptor (GHS-R), to which ghrelin binds, was present in bovine liver and adipose tissue, but not sternomandibularis muscle. Abundance of GHS-R did not differ as a result of dietary treatment in bovine liver and adipose tissue. Abundance of GHS-R in bovine liver and adipose tissue increased as cattle became increasingly fatter. Differences in plasma ghrelin concentrations relative GHS-R abundance in liver and adipose tissue warrants further investigation into the role of ghrelin in growth and efficiency in cattle.
Nutrient restriction and abundance during a specific period in mid-gestation altered expression of genes involved in the development of adipose tissue but did not influence calf birth weight or crown-rump length. This justifies further investigation into the long-term impact of maternal nutrition on growth and carcass composition of beef offspring.
Utah State University
Plant tannin extracts inhibited the in vitro growth of pathogenic and ruminal acidosis-causing bacteria. In one experiment, chestnut tannins (CNT) were the most effective followed by mimosa (MT) tannins across all pathogen studied while quebracho tannins (QT) did not affect bacterial growth. In another experiment, CNT decreased the growth of Streptococcus bovis 73% at 24 h.
Objective 3. To enhance the environmental sustainability of the feedlot industry through N, P, K, and S management by improving nutrient utilization and excreted nutrient conservation.
Michigan State University
As DDGS replaced high moisture corn in finishing diets (0, 40%, or 60% DDGS) sulfur increased linearly from 13.3 to 44.6 g/d and total S expelled increased linearly. However, total S air emissions/unit of S intake were greatest for 40% and least for 0% DDGS. Retention of S was similar across level of DDGS inclusion. In a second study, finishing diets containing 40% DDGS resulted in greater H2S emissions than diets containing 0% DDGS, but the addition of 6 ppm Mo and 60 ppm Cu to 40% DDGS diets numerically reduced H2S emissions 23% compared to no additional Mo and Cu. The addition of Mo and Cu did not change the route of S removal from the animal.
Objective 4. To enhance the health and production efficiency of feedlot cattle through management strategies and technologies which enhance cattle comfort and wellbeing.
Michigan State University
Tail docking did not affect finishing performance or carcass quality of cattle finished in a slatted-floored barn (7 hd per pen; 20 ft2/hd; 160 d on feed) compared to cattle whose tails were not docked. However, the incidence of tail lesions was higher for calves without docked tails (n=12) compared to those with docked tails (n=1; P = 0.004). Tail docking did not affect the incidence of lameness of other health indices.
Oklahoma State University
There were no differences on feedlot performance between bull calves surgically castrated by knife or elastration. Knife cut calves experienced greater morbidity than elastrated calves. Steers had greater ADG, improved feed efficiency and lower morbidity compared to bulls, resulting in improved cost of gains. Bulls should be bought at 6.1% discount compared to steers due to decreased performance.
Management information was able to be effectively and securely communicated to and from active ear tags in scenarios where cattle were managed in a manner consistent with common production practices.
