In Vivo And In Vitro Expression Of Porcine Zinc Transporter (Znt) 1 Mrna, Huyen Tran, Phillip S. Miller, Thomas E. Burkey
Nebraska Swine Reports
Preliminary experiments were carried out to evaluate in vivo expression of zinc transporter (ZnT) 1 mRNA in a panel of tissues obtained from weaned pigs and to evaluate in vitro changes in Z n T l mRNA in a porcine jejunal epithelial cell line (IPEC-J2) treated with low (40 yM) or high (80 yM) concentrations of zinc sulphate (ZnSO,) or, in a separate experiment, with low (50 yg/ml) or high (1 00 yg/mL) concentrations of antibiotics (as gentamicin; GENT). Lipopolysaccharide (LPS; 10 ng/mL) was included as a negative control in both experiments. Zinc transporter 1 mRNA was detected in all …

Effect Of Dam Parity On Litter Performance And Passive Immunity, Erin E. Carney, Huyen Tran, Justin W. Bundy, Roman Moreno, Matthew Anderson, Jeffrey Perkins, Philip S. Miller, Thomas E. Burkey
Nebraska Swine Reports
Preliminary experiments (reported in the 2008 Nebraska Swine Report) suggest that progeny health status may be affected by dam parity. However, the preliminary experiments only included a small population of sows and their progeny. Therefore, the objective of the current experiment was to evaluate litter performance and the production and passive transfer of immunoglobulins (Ig) in dams (P1 vs. P4) and their progeny. Litter birth weight tended (P < 0.10) to be greater for P4 progeny compared to P1 progeny. No effects of dam parity were observed on circulating Ig in dams during gestation or at parturition. However, concentrations of IgA tended (P < 0.09) to be greater for P4 sows compared to P1 gilts in samples of colostrum and milk and serum IgG concentrations were greater (P < 0.02) for P4 progeny compared to P1 progeny across all preweaning samples. These results suggest that litter performance and health status may be affected by dam parity.

Effects of allowing gilts ad libitum access to feed until breeding age or developing them with 25% energy restriction from 123 days of age to breeding on reproductive success through parity 1 were studied with a total of 639 gilts of two lines that differ in lean growth and reproduction. Gilts of the two lines had common sires, an industry maternal line, but dams were from different populations. One line of gilts, LW x LR, represented standard industry Large White x Landrace cross females. The other gilts, L45X, were daughters of Nebraska selection Line 45 that has been selected 27 …

Nebraska Swine Reports
Forty pigs were used in a 14-week, 4-phase regime study conducted to evaluate the feeding value of diets with varying concentrations of DDGS for growing-fi nishing pig formulated on a standardized ileal digestibility (SID) lysine (lys) basis, DDGS withdrawal at the last feeding phase, and ractopamine (RAC)supplementation four weeks prior harvesting. Treatments consisted in 0, 15 or 40% dietary DDGS inclusion supplemented or not with RAC (4.5 ppm) four weeks prior harvesting. Increased dietary DDGS inclusion resulted in a linear reduction in average daily gain (ADG) during the Grower 1 period (P = 0.002). There were no treatment effects (P …

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
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 …

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.

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.

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 …

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 …

Impact Of Repeated Out-Of-Feed Events And Fineness Of Grind On Grow-Finish Performance, Mike Brumm, Sheryl Colgan
Nebraska Swine Reports
Out-of-feed events are a growing problem in nursery and grow-finish facilities due to issues associated with feed delivery to bulk bins and bridging of feed in bulk bins. Reports of bridging are increasing as producers continue to reduce the fineness of grind for complete diets in order to improve feed conversion. A study was conducted to examine the effect of repeated out-of-feed events and diet particle size on barrow performance in a wean-to-finish facility beginning six weeks after weaning. Corn-soybean meal based diets were either coarse (1,266 microns) or medium ground (1,019 microns) for the duration of the experiment. Within …

Litter size plays a major role in the economics of pork production. Even modest increases in average litter size can have considerable effects on overall profitability. Two major components of litter size – ovulation rate and embryonic survival – have been used in a selection index project ongoing for several generations at the University of Nebraska–Lincoln (UNL). Additionally, the Chinese Meishan breed is one of the most prolific breeds, producing four to five more pigs per litter than white crossbred females. We investigated the role of the gonadotropin-releasing hormone (GnRH) receptor and gonadotropin subunit genes in determination of ovulation rate …

The amount of drinking water needed daily by the pig depends on numerous influences, including temperature, diet, stage of production and health. Within a 24-hour period under thermal-neutral conditions, grow-finish and gestating swine demonstrate a peak in water usage in late afternoon while lactating females consume water more consistently throughout the day. In times of heat stress, grow-finish pigs alter their water usage pattern with a peak between 8 to 9 a.m. and second peak around 5 to 8 p.m. Daily drinking water needs for pigs range from less than 0.5 gal/pig/day for newly weaned pigs to greater than 1.5 …

The business decisions pork producers make are extremely important. Decisions increase in importance at the same time they become harder to make. In business management studies, time has been devoted to learn how such decisions can be made. Less study has been expended on how producers currently make decisions. In the United States, family producers have traditionally made decisions with information they could gather independently. The ability to create decision making information is difficult. Producers need to remember the key success item — that of effective management led by sound decisions. The process of decision making involves skills and abilities …
