Effect Of Dam Parity On Growth Performance And Immunity Of Weaned Pigs, Erin E. Carney, Huyen Tran, Justin W. Bundy, Roman Moreno, Phillip S. Miller, Thomas E. Burkey

Nebraska Swine Reports

The growth performance of weaned pigs derived from different parities has not been previously evaluated; however, unpublished and anecdotal observations suggest that progeny derived from first parity (PI) dams have reduced health status and growth performance compared to progeny derived from mature sows (2 P2). The objective of the current study was to evaluate the effect of dam parity on growth performance and immune response of PI and P4 progeny during the nursery phase o fproduction. Results from this experiment suggest that P4 progeny have increased body weight and growth performance during the nursery phase of production compared to PI …

Effect Of Dam Parity On Litter Performance And Passive Immunity, Erin E. Carney, Huyen Tran, Justin W. Bundy, Roman Moreno, Matthew W. Anderson, Jeffrey M. Perkins, Phillip 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 (PI 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.

Effect Of Corn Dried Distillers Grains With Solubles (Ddgs) On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts With Previous Exposure To Ddgs In The Nursery, Thomas E. Burkey, Philip S. Miller, Roman Moreno, Erin E. Carney

Nebraska Swine Reports

The objective of this experiment was to evaluate the effects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics of gilts, during growing-finishing, that were previously fed high concentrations of DDGS during the nursery phase. Overall (week 1 to 16), the following observations are noteworthy: 1) among pigs that were fed DDGS in the nursery, average daily gain (ADG) and final body weight (BW) tended (P < 0.10) to be lower during growing-finishing compared to pigs that did not receive DDGS in the nursery; 2) among pigs that received DDGS during growing-fi nishing, ADG tended (P < 0.10) to be lower compared to pigs that did not receive DDGS during growing-finishing; and 3) among pigs that received DDGS in both the nursery and during growing-finishing, ADG and fi nal BW was decreased (P < 0.04) compared to pigs with no prior exposure to DDGS. With respect to carcass characteristics, 10th-rib back fat was greater (P < 0.05) at the end of finisher 2 among pigs that did not receive DDGS in the nursery and hot carcass weight tended (P < 0.07) to be decreased among pigs that received DDGS in both the nursery and during growing-finishing. This research indicates that the inclusion of high concentrations of DDGS in both the nursery and growing-finishing periods may result in negative effects on growth performance and carcass characteristics.

Selection For Immune Responses To Porcine Circovirus (Pcvz) To Decrease Incidence Of Porcine Circovirus Associated Disease (Pcvad), Jared S. Bates, Roman Moreno, Alan R. Doster, Rodger K. Johnson

Nebraska Swine Reports

Genetic and environmental effects on incidence of Porcine Circovirus Associated Disease (PCVAD) and immune responses to Porcine Circovirus 2 (PCVZ), and their relationships with body weights were studied in 3,440 pigs of the Nebraska litter size selection lines. Pigs were weighed at birth, weaning, 65, and 180 days of age and scored for symptoms of PCVAD every 10 days from 70 to 180 days of age. Necropsies were performed to confirm accuracy of scoring. PCV2 viremia, and antibodies to PCV2, Porcine Reproductive and Respiratory Syndrome Virus, Mycoplasma hyopneumoniae and Actinobacilluspleuropneumoniae were measured in serum from blood samples drawn at various …

Nebraska Swine Reports

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 I 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 27generations …

Effects Of Distillers Dried Grains With Solubles (Ddgs) And Paylean" Supplementation On Growth Performance Of Growing-Finishing Pigs, Roman Moreno, Phillip S. Miller, Thomas E. Burkey, Matthew Anderson, Jeffrey Perkins, Donald R. Mcclure, Thomas Mcgargill

Nebraska Swine Reports

Forty pigs were used in a 14-week, +phase regime study conducted to evaluate the feeding value of diets with varying concentrations of DDGS for growing-finishing 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 …

Explanation Of Statistics Used In This Report

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. At the end of an experiment, the experimenter must decide whether observed treatment differences are due to "real" effects of the treatments or to random differences due to the sample of pigs assigned …

Feeding Value Of Diets For Growing-Finishing Pigs With Varying Concentrations Of Corn Distillers Dried Grain With Solubles (Ddgs), Roman Moreno, Philip S. Miller, Thomas E. Burkey, Matthew Anderson, Jeffrey Perkins, Donald Mcclure, Thomas Mcgargill

Nebraska Swine Reports

Two-hundred and forty pigs (61.73 lb) were used in a 16-week study conducted to evaluate the feeding value of diets with varying concentrations of distillers dried grains with solubles (DDGS) for growing-finishing pigs. Pigs were assigned to one of four dietary treatments. Treatments consisted of a standard diet formulated on a standardized ileal digestible lysine (SID lys) basis in which a portion of dietary corn and soybean meal were replaced to include 0, 5, 10 or 15% of DDGS in a 4-phase feeding regime. Treatment did not affect average daily gain (ADG), average daily feed intake (ADFI) or gain/feed (G:F) …

Economy Of Adding Fibrous Feedstuffs To Sow Gestation Diets, Duane Reese, Allen Prosch

Nebraska Swine Reports

A previous summary of research results indicated that sows fed high-fiber diets during gestation weaned 0.3 more pigs/litter on the average than sows fed lower-fiber, grain-based diets. Gestation diets containing 18% soybean hulls, 46% distillers dried grains with solubles (DDGS), 34% wheat midds, 25% wheat bran, 23% alfalfa meal, 25% sugar beet pulp, or 45% oats provide sows about 350 g/day of neutral detergent fiber (NDF), which may be sufficient to increase litter size weaned by 0.3 pigs per litter. An economic analysis suggests that feeding a diet containing these sources of NDF would increase sow feed ingredient costs from …

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.
