Effects Of Increasing Concentrations Of Distillers Dried Grains With Solubles (Dldgs) On Growth Performance Of Weaning Pigs, Thomas E. Burkey, Phillip S. Miller, Swapna Sheperd, Roman Moreno, Erin E. Carney
Nebraska Swine Reports
The objective of this experiment was to evaluate growth performance of weanling pigs introduced to low concentrations (5%) of DDGS during phase 2 of the nursery period followed by high concentrations (30%) during phase 3 of the nursery period Overall (day 0 to 42), pigs fed 5 or 30% DDGS in phase 2 (and 30% DDGS in phase 3) had decreased (P < 0.05) average daily gain (ADG) compared to control pigs. In addition, pigs fed 30% DDGS (during phase 2 and 3) had decreased (P < 0.05) body weight (BW) compared to control pigs and pigs that only received DDGS during phase 3. However, pigs fed 0% DDGS during phase 2 followed by 30% DDGS in phase 3) had similar BW, ADG and average daily feed intake compared to pigs fed the control diet. This research indicates that the inclusion of DDGS during phase 2 of the nursery may negatively affect growth performance, particularly when followed by inclusion of high concentrations of DDGS during phase 3 of the nursery period. However, growth performance may be maintained when high concentrations of DDGS are included in the diets of pigs (with no previous exposure to DDGS) late in the nursery period.

Nebraska Swine Reports
An experiment was conducted to determine the effects of energy restriction during the gilt development period on lifetime sow reproductive performance of two maternal lines. There were essentially no interactions among line, dietary treatment, and parity. The Large White x Landrace gilts were heavier before and after dietary treatments, matured later, and had greater longissimus muscle area compared to Nebraska Line gilts. Restricting energy intake during the developmental period increased litter weaning weight but had no affect on litter size. Nutritional management of prolific sow lines during the gilt development period does affect sow and litter performance. However, these results …

Nebraska Swine Reports
Gilts of two genetic lines were developed with either ad libitum access to feed or energy restriction (75% of ad libitum) to determine effects on subsequent sow performance and longevity. Gilts can be developed with regimens in which energy is restricted during the growing period but the proportion that express pubertal estrus may be reduced in leaner, faster growing lines. Effects on subsequent farrowing rates are small. Sow weight and buckfat at farrowing and weaning of Parity 1 litters affect the likelihood of producing a Parity 2 litter, but these effects are dependent on lean growth rate of the line …

Nebraska Swine Reports
Pigs treated alike vary in performance due to their different genetic makeup and to environmental effect we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an "equal" group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

Speakers included faculty from the University of Minnesota, Iowa State University, and Kansas State University and veterinary practitioners from Iowa and Minnesota. Many of the topics focused on details relating to on-farm and off-farm biosecurity measures. Economic impacts of PRRSV and PCV2 infections were discussed in terms of specific case reports.
Does Dam Parity Affect Progeny Health Status?, Thomas E. Burkey, Phillip S. Miller, Rodger K. Johnson, Duane Reese, Roman Moreno
Does Dam Parity Affect Progeny Health Status?, Thomas E. Burkey, Phillip S. Miller, Rodger K. Johnson, Duane Reese, Roman Moreno
Nebraska Swine Reports
A preliminary experiment was conducted to investigate the health status of progeny derived from different parities; health status was characterized by evaluating the ability of Pl and P3 dams to produce and passively transfer immunoglobulins (IgA and IgG) to their progeny. At parturition, circulating concentrations of IgA and IgG were greater (P < 0.01 ) in P3 dams compared to P1 dams. As expected, during lactation, concentrations of IgA and IgG were greater (P < 0.002) in colostrum compared to milk (mid- and late-lactation). No parity differences were observed in immunoglobulin concentrations in colostrum or milk obtained from P1 and P3 dams. However, when immunoglobulins were quantified in the progeny of Pl and P3 dams a parity x time interaction was observed for circulating IgG (P < 0.03) and a trend for a parity x time interaction was observed for IgA (P = 0.06). Within a time point (d), serum IgG was greater (P < 0.001) in P3 progeny compared to P1 progeny for each time point measured. These results suggest that health status, as indicated by circulating immunoglobulin concentration, in neonatal pigs, may be affected by dam parity.

Estimation Of The Lysine Requirements For High-Lean Growth Pigs, Phillip S. Miller, Roman Moreno, Thomas E. Burkey, Rodger K. Johnson
Nebraska Swine Reports
An experiment was conducted to determine the lysine regime required to maximize growth performance for high-lean-growth potential barrows and gilts beginning at 45 lb and concluding at approximately 260 lb. There were four growing-finishing phases and four lys treatments within phase (Grower-1, 44 lb to 79 lb; Grower-2 79 lb to 132 lb; Finisher-1, 132 lb to 189 lb; and Finisher-2, 1891b to 260 lb). Dietary treatments were corn-soybean meal based supplemented with 0.15% crystalline lysine. The formulation of 2 dietary treatments was aimed to provide lysine below the requirement, while the other 2 dietary treatments provided lys above the …
Dietary Fiber In Sow Gestation Diets - An Updated Review, Duane Reese, Allen Prosch, Daryl A. Travnicek, Kent M. Eskridge
Dietary Fiber In Sow Gestation Diets - An Updated Review, Duane Reese, Allen Prosch, Daryl A. Travnicek, Kent M. Eskridge
Nebraska Swine Reports
Twenty-four published reports dating from 1975 to 2007 were examined to determine the overall effects of feeding gestation sows additional fiber. Sow and litter traits among trials were weighted by the number of litters for each treatment within each trial. Overall, sows can successfully consume high-fiber diets during gestation with few deleterious effects. Positive effects from feeding high-fiber diets were evident in litter size (0.2 to 0.6 pigs/litter) and sow lactation feed intake (0.5 to 0.8 lb/day), but they are not largely evident until the second reproductive cycle following exposure to the diet. It's possible that to ensure sow and …

Effects Of Organic Acid Salts On The Quality Characteristics Of Whole Muscle Hams, Karaline A. Poovey, Dennis E. Burson, Roger W. Mandigo, Susan L. Cuppett, Harshavardhan Thippareddi
Nebraska Swine Reports
The use of organic acid salts in the meat industry enhances product shelf life and safety. Minimal research is available evaluating the effects of high levels of organic acid salts on quality and sensory attributes of ready-to-eat products. Whole muscle hams were cured with brine solutions containing one of the following organic acid salt additions: 0% Control; 2.5 or 3.5% L-sodium lactate and sodium diacetate; 1.3,2.5, or 3.5% buffered sodium citrate; 1.3,2.5, or 3.5% buffered sodium citrate and sodium diacetate. The increased use of organic acid salts decreased product moisture and cooking yield (P < 0.05). Sensory panelists perceived decreased overall acceptability, with increased sourness/acidity and bitterness. Moderate levels of organic acid salts provided more acceptable products while maintaining many sensory attributes. Meat processors choosing to use organic acid salts in ready-to-eat products should be cautious as product yield losses and flavor changes may outweigh benefits at certain levels.

Association Of Odor Measures With Annoyance: Results Of An Odor-Monitoring Field Study, Richard R. Stowell, Christopher G. Henry, Richard K. Koelsch, Dennis D. Schulte
Nebraska Swine Reports
Multiple assessments of ambient odor were made by trained individuals around a swine finishing operation in eastern Nebraska. Assessor responses were analyzed to determine relationships between field odor measurements/ ratings and ratings of annoyance potential, and to identify candidate measurement threshold values for causing annoyance. The likelihood of annoyance increased as odors became more offensive, intense, and concentrated, with r2 values of 0.89, 0.81, and 0.64, respectively. Candidate thresholds were sought to delineate both “any degree of stated annoyance" and "consequential annoyance," defined as likely causing a change in behavior or activity level and instilling some memory of the …

Validating The Odor Footprint Tool Using Field Data, Richard R. Stowell, Kara R. Niemeir, Dennis D. Schulte
Nebraska Swine Reports
Trained participants monitored odors around a 4,800-head finishing site in eastern Nebraska during 2005 and 2006. “Mobile odor assessors” monitored odors within the downwind odor plume and reported that odors at off-site locations (at least 200 feet away) were consequentially annoying in 20 out of 192 assessments. On-site odor levels were considered annoying in 33 of 39 instances. For the same off-site locations and times, modeling predicted 18 annoying events, resulting in 90% prediction rate (18 vs. 20) of annoying frequency. Five residents regularly monitored for odors outside their residences and made 1,007 assessments. On 42 occasions, or 4.2% of …

Nebraska Swine Reports
A study was conducted to evaluate the effect of feeding 0,5,10 or 15% distillers dried grains with solubles (DDGS) on carcass quality, color stability, and sensory characteristics of the longissimus muscle (LM) of finishing pigs. Live weight and hot carcass weight decreased as dietary DDGS increased (P < 0.05). Dressing percentage did not differ among treatments (P - 0.72). After 10 days of retail display, no differences were observed among treatments for color or color change (P > 0.05). No differences in shear force were observed (P = 0.34). Total unsaturated fatty acids increased and total saturated fatty acids decreased (P < 0.05) as dietary DDGS increased. Treatments did not affect sensory characteristics (P > 0.05). The results of this investigation suggest that dietary DDGS inclusion altered fatty acid profile of the backfat of pigs by reducing total saturated fatty acid and increasing total unsaturated …

Effect Of Increasing Lysine:Net Energy Ratio On Growth Performance And Plasma Urea Nitrogen Concentration Of Late-Finishing Barrows Fed Low-Protein Amino Acid-Supplemented Diets And Ractopamine, Roman Moreno, Phillip S. Miller, Thomas E. Burkey
Nebraska Swine Reports
An experiment was conducted to determine the optimum lysine (lys):Net energy (NE) ratio of low-crude protein (CP) amino acid (AA)-supplemented diets needed in conjunction with ractopamine (RAC) to improve growth performance of late-finishing barrows from the University of Nebraska-Lincoln (UNL) herd. Treatments consisted of jive low CP, AA-supplemented diets with addition of ractopamine (16% CP; 4.5g/ton), formulated to contain 3.35, 3.95,4.57, 5.2 and 5.83 g of lys/Mcal of NE. A corn-soybean meal diet with no RAC supplementation served as negative control (20% CP; 5.24 g of Lys/Mcal of NE). Treatment did not affect growth performance (P > 0.05). Despite the lack …
