Swine Extension

Reprinted with permission from Vol. 90, No. 11, November 5, 2018 As we described in part 5 of this series, the relatively high fiber content of dried distillers grains plus solubles (DDGS) significantly reduces the ratio of net energy (NE) to gross energy (GE) in corn DDGS fed to swine. As a result, there has been tremendous interest in supplementing DDGS diets with various commercially available carbohydrases and proteases to increase the NE:GE ratio in corn DDGS. Swiatkiewicz et al. (2015) summa rized responses from adding various enzymes to corn DDGS diets for swine (Table 1). In general, the majority of these studies showed improvements in nutrient digestibility when enzymes were added to corn DDGS diets, but these were often not associated with improvements in growth performance. Several studies summarized evaluated only phytase responses and not com bination...

By Drs. Jerry Shurson and Pedro Urriola, University of Minnesota Department of Animal Science © 2018 Feedstuffs. Reprinted with permission from Vol. 90, No. 10, October 1, 2018 The gross energy (GE) content of corn dried distillers grains plus solubles (DDGS) – at 5,429 kcal/kg of dry matter – is much greater than the 4.45 kcal/kg of dry matter for corn, 4,730 kcal/kg for soybean meal and the GE of other common ingredients used in swine diets.  However, the efficiency with which pigs utilize GE in DDGS, as measured by the net energy (NE)-to-GE ratio, is low (0.49) compared with corn – at 0.49 versus 0.68, respectively (National Research Council, 2012) – but NE:GE can vary from 0.42 to 0.46 among DDGS sources with variable crude fat content (Kerr et al., 2015). Of all of the chemical components in feed ingredients, lipids provide the greatest amount of NE (kcal/kg), followed by crude protein and starch, with a limited amount provided from dietary fiber (Noblet and van Milgen...

Reprinted as posted on Swine in Minnesota blog A scientific article written by Dr. Fabian Chamba Pardo when he was doing his PhD in the Torremorell lab was recently published in the journal of Preventive Veterinary Medicine . The study presented aimed to look at the various factors influencing the influenza infection status of piglets at weaning. Highlights Sow vaccination decreased influenza infections in piglets at weaning. Influenza positive gilts at entry were associated with positive piglets at weaning. More work is needed to assess herd closure, gilt isolation and gilt vaccination.

By Erin Cortus, Assistant Professor and Extension Engineer, University of Minnesota Originally appears in The LAND – October 19/October 26, 2018 Fall is a transition season. After crop removal, while temperatures are cool and before soil is frozen, is an opportune time to transfer manure from manure storages to the soil for next year’s crop use. Ventilation goes hand in hand with manure pumping activities. However, fall weather also means large temperature and wind fluctuations are likely, and these conditions influence ventilation system management and performance. This article dives into ventilation strategies and considerations while pumping manure. But first…manure pumping safety considerations are widely published and shared, but it never hurts to share them one more time! Manure pumping includes both agitation and pumping or removal out of the barn. Agitation creates a larger disruption of the manure volume. Any disruption of stored manure promotes the release of gase...

Swine producers and agribusinesses in Southern Minnesota are welcome to attend a Swine Energy Management Seminarat the Knights of Columbus Hall, 920 East 10th Street, Fairmont on Thursday, November 15 from 10:00 a.m. - 12:30 p.m.  Attendees will hear about: Mapping out your plan for Energy Efficiency: An Energy Audit - Jill Eide, Certified Energy Manager of Great River Energy Great River Energy incentives for Farm Energy Audits What an Energy Audit covers How to use your Energy Audit: rebates, NRCS and REAP funding Panel of area farmers who have implemented smart energy technologies Straight talk about on-farm solar energy from UMN Extension CERTs Program - Fritz Ebinger Financial and energy modeling Tax credits and explanation of utility fee structure On-farm siting considerations

Heavy rains this summer and fall have caused concerns about the development of fungi molds in grain. Some fungi molds in grain can produce harmful compounds called mycotoxins. Pigs consuming mycotoxins above their tolerance level will face health and reproductive problems. Producers can find facts to help them manage fungi molds in feed grains here: https://z.umn.edu/ManageMycotoxinsInFeedGrain

By: Liz Stahl, Crops Extension Educator and Seth Naeve, Extension Soybean Agronomist As posted on the Minnesota Crop News Blog While almost impossible to accomplish in most years, harvesting soybeans at a moisture content between 13 to 15% helps maximize yields while minimizing harvest losses. Cool, cloudy, and rainy conditions this fall, however, have led to large increases in soybean moisture content. With cool conditions in the forecast, soybeans may be harvested at much higher moisture levels this fall than usual. Continue Reading

Are you looking for financing for your farm and not sure where to begin or want to know about the variety of financing options? "Micro-Loans, Grants, and Traditional Farm Financing" workshop is presented by the University of Minnesota Extension's Women in Ag Network (WAGN). The WAGN is a collaboration of Extension with USDA's Minnesota Farm Service Agency. When: December 13, 2018 - Registration at 9:45 a.m.; Program 10:00 a.m. - 2:00 p.m. with lunch Where: Willmar Regional Extension Office, 1802 18th St. NE, Willmar, MN Cost: $15 (includes lunch) Register: z.umn.edu/WAGN-Financing ; deadline to register is December 7, 2018

The United States Department of Agriculture's Farm Service Agency (FSA) offices have updated their guidance for the Market Facilitation Programs (MFP). FSA has further clarified ownership dates for inventory numbers. MFP Pig Ownership Number of live animals in ownership. Producers may select any date from July 15, 2018 through August 15, 2018 as the date for which ownership is reported. Hogs must be produced for commercial marketing.

By Dr. Jerry Shurson, University of Minnesota Department of Animal Science © 2018 Feedstuffs. Reprinted with permission from Vol. 90, No. 9, September 4, 2018 Despite the high nutritional and economic value of adding high amounts of dried distillers grains plus solubles (DDGS) to growing/finishing pig diets, one of the challenges has been to minimize its effect on reducing carcass yield and pork fat quality. However, it is well documented that feeding DDGS has no appreciable effects on pork lean quality and sensory charac teristics and, therefore, provides a con sumer eating experience similar to pork produced from pigs fed corn/soybean meal diets (Xu et al., 2010b; Leick et al., 2010; McClelland et al., 2012). One of the most consistent effects of feeding DDGS diets to growing/finishing pigs is a slight reduction in carcass yield. Although this response does not always occur when feeding DDGS diets, it is fairly common. The reduction in carcass relative to liv...
