Nebraska Supreme Court Rules City Can Regulate Animal Feeding Operation, J. David Aiken
Nebraska Supreme Court Rules City Can Regulate Animal Feeding Operation, J. David Aiken
Nebraska Swine Reports
Nebraska statutes authorize second class cities and villages to adopt regulations protecting municipal water supplies from pollution within 15 miles of their community borders. Livestock facility regulations implemented by the second class city of Alma that were stricter than those of the Nebraska Department of Environmental Quality were upheld by the Nebraska Supreme Court. However, similar municipal regulations may be vulnerable to future legal attacks.

Dietary Antimicrobials In A Wean-To-Finish Facility, Mike Brumm
Nebraska Swine Reports
The routine use of growth-promoting antimicrobial feed additives is under increasing pressure worldwide. In response to this pressure, it is important that producers and their advisors understand under what circumstances these additives are likely to be effective or ineffective, allowing for improved decisions regarding their use. An experiment was conducted to examine the routine use of antimicrobial feed additives in a wean-to-finish facility. The weaned pigs used in this experiment were purchased from a source where grow-finish pigs were positive for PRRSV, circovirus-2 and Mycoplasma hyopneumoniae and had a previous history of Actinobacillus pleuropneumoniae (APP) related problems. Experimental treatments were …
Crop Residue Cover And Manure Incorporation — Part I: Reduction Of Cover, David P. Shelton
Crop Residue Cover And Manure Incorporation — Part I: Reduction Of Cover, David P. Shelton
Nebraska Swine Reports
Manure incorporation represents a compromise between best management practices for soil erosion control and manure management. Manure should be incorporated into the soil for odor control, increased availability of nutrients and control of potential manure runoff. However, soil and crop residue disturbance should be minimized for soil erosion control. This field study was conducted to: 1) determine the influence that commercially available soil-engaging components used to simultaneously apply and incorporate manure have on the reduction of crop residue cover [Part I - this article]; and 2) determine and evaluate some of the factors that may influence the amount of residue …

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.
Energy And Nitrogen Utilization Of Corn Rootworm Protected Corn (Event Mon 863) And Similar Non-Transgenic Corn In Young Pigs, Robert L. Fischer, Phillip S. Miller
Energy And Nitrogen Utilization Of Corn Rootworm Protected Corn (Event Mon 863) And Similar Non-Transgenic Corn In Young Pigs, Robert L. Fischer, Phillip S. Miller
Nebraska Swine Reports
This experiment was conducted to compare the nutritional value, measured by digestible and metabolizable energy, and nitrogen digestibility in young pigs fed either corn rootworm protected test corn (event MON 863, RX740CRW) or a genetically similar non-transgenic control corn (RX740). The experiment used 12 barrows with an initial body weight of 74.5 lb. The pigs were housed individually in stainless steel metabolism crates and were randomly allotted to one of two corn treatments, either corn rootworm protected corn or non-transgenic control corn. Diets were formulated to contain 97.5% of test or control corn and 2.5% minerals and vitamins. The duration …

Nebraska Swine Reports
Two 4-week experiments were conducted to determine body composition and lysine utilization for protein deposition (PD) in barrows and gilts. Thirty-two growing pigs (16 barrows and 16 gilts; average initial body weight of 40.4 lb) were used in each experiment. Pigs were randomly allotted to one of seven dietary treatments. Four pigs (two barrows and two gilts) were killed at the start and the remaining pigs were killed at the end of the experiments to determine body composition. There were two replications per treatment in each experiment for a total of four replications. Dietary treatments consisted of a basal diet …

Effect Of Increasing Dietary Crude Protein Concentration On Growth Performance And Serum Insulin-Like Growth Factor-I Concentration, Robert L. Fischer, Phillip S. Miller
Nebraska Swine Reports
This study was conducted to investigate the effects of increasing dietary protein intake on growth performance and serum insulin-like growth factor-I (IGF-I) concentration in growing-finishing gilts. Thirty-nine crossbred gilts with an initial body weight of 74.3 lb were used in a 28-day growth study. The gilts were randomly allocated to one of five dietary treatments. The diets were standard corn soybean meal diets, which were formulated to contain 10, 14, 18, 22, or 26% crude protein by changing the ratio of corn to soybean meal in the diet. Pig and feeder weights were recorded weekly for the determination of average …
Update On Omega-3 Fatty Acids And Litter Size In Swine, Duane Reese
Update On Omega-3 Fatty Acids And Litter Size In Swine, Duane Reese
Nebraska Swine Reports
A literature review was conducted to examine the role that dietary omega- 3 fatty acids may have in improving litter size in swine. Omega-3 fatty acids are not normally present to any great extent in practical swine diets, but they are increasingly believed to be important in human and pet health. In all but one of the studies reviewed the number of pigs born alive improved (0.2 to 0.7 pigs litter) when sows were provided diets that contained more omega-3 fatty acids. In all the studies that reported litter size at weaning, positive responses were observed (0.3 to 1.3 pigs/litter) …
Team Approach To Management, Allen Prosch
Team Approach To Management, Allen Prosch
Nebraska Swine Reports
Managerial ability has been described as consisting of supervision and coordination. The coordination aspect is that function of deciding what business arrangements should be entered into. Pork producers are being called on to justify their right to do business with records that assure society that they have complied with regulations and used best management practices. Coordinating all the business activities to ensure compliance challenges the ability of any manager. The greater need for coordinating ability strongly suggests that pork producers who develop greater coordinating capacity will have a competitive advantage. Team management will be a necessary component in creating that …

Major Genes Affect Reproduction And Early Growth, Rodger K. Johnson, J. W. Holl
Nebraska Swine Reports
The Nebraska Index Line is reproductively superior to its contemporary control, producing approximately four pigs more per litter. However, the genes or quantitative trait loci (QTL) that cause these differences are unknown. A previous study with an F2 resource population created by crossing the NE Index and Control lines identified one QTL affecting ovulation rate, one QTL affecting number of fully formed fetuses, one QTL affecting number of pigs born alive, two QTL affecting number of stillborn pigs, five QTL affecting nipple number, and six QTL affecting age at puberty. However, individual birth weight and weaning weight had not been …

Livestock Friendly Counties Statute Enacted, J. David Aiken
Nebraska Swine Reports
LB754, adopted in 2003, (1) allows the Nebraska Department of Agriculture to designate counties as livestock friendly and (2) changes procedures for county livestock zoning permits. Counties must upon request specify what an applicant must do in order to obtain a livestock zoning permit. Counties must provide written statements regarding why a livestock zoning permit is granted or denied. Applicants can upon request be informed of whether they will receive a county zoning permit before applying to the Nebraska Department of Environmental Control for a livestock waste control facility permit. LB754 is the latest (but not the final) chapter in …
Property Valuation May Be Reduced By Proximity To Livestock Operation, J. David Aiken
Property Valuation May Be Reduced By Proximity To Livestock Operation, J. David Aiken
Nebraska Swine Reports
Livestock odors must be taken into account when counties determine the fair market value of rural residences for property tax purposes. Livestock odors may reduce property values and property valuation. Such reductions may lead to legal nuisance liability claims against livestock producers who are not protected by the Nebraska Right to Farm Act, and may also become a factor in livestock facility zoning decisions.

Role Of The Gonadotropin-Releasing Hormone (Gnrh) Receptor In Determination Of Ovulation Rate Between Lines Of Swine, Benjamin E. Bass, Ginger A. Mills, Brett R. White
Nebraska Swine Reports
Litter size plays a major role in the economics of swine production. Even modest increases in average litter size can have considerable effects on overall profitability. Two major components of litter size, 1) ovulation rate, and 2) embryonic survival, have been used in a selection index project ongoing for several generations at the University of Nebraska-Lincoln (UNL). To better understand the mechanisms of one component, ovulation rate, we are investigating the role of the gonadotropin-releasing hormone (GnRH) receptor in determination of this important trait. Although other factors may influence determination of ovulation rate, this receptor has an established physiological importance …
Where Can I Build Or Expand A Livestock Operation? A Case Study Of Cuming County, Nebraska, Christopher G. Henry, Jeff Arnold
Where Can I Build Or Expand A Livestock Operation? A Case Study Of Cuming County, Nebraska, Christopher G. Henry, Jeff Arnold
Nebraska Swine Reports
The impacts that setback distances of 1/4, 3/8, 1/2, 3/4, and 1 mile would have on the land area available to the livestock industry for expansion in Cuming County, Neb. were estimated using a geographic information system and the current county zoning requirements. These setbacks seem to be typical of distances cited in many county zoning regulations. Setback distances greater than 3/8 of a mile appear to be very exclusive to expansion of the livestock industry in Cuming County. Reciprocal setbacks that apply to new housing construction do not appear to be restrictive. It is expected that other Nebraska counties …

Supplementation On Sow And Litter Performance, Subsequent Weanling Pig Performance And Intestinal Development After An Immune Challenge, Steve J. Kitt, Phillip S. Miller, Robert L. Fischer
Nebraska Swine Reports
Sixteen sows were randomly assigned to two treatments: CON: Control corn-soybean meal diet; GLN: Cornsoybean meal diet + 2.5% crystalline glutamine. No differences (P > 0.10) between treatments were observed for sow weight loss, sow feed intake, or litter weight gain. Sow plasma glutamine concentration tended to be increased on days 7 and 21 (P < 0.13) in sows fed GLN. Milk glutamine concentration was increased (P < 0.08) on days 7 and 21 of lactation. However, suckling pig plasma glutamine concentration was not altered (P > 0.38) on day 21 by glutamine enriched milk consumption. On day 21, pigs were weaned to a common starter diet, sow treatment structure was maintained, and two additional treatments were imposed on weanling pigs and arranged in a 2 x 2 factorial: SAL: Saline injection on …

Nebraska Swine Reports
The objective was to determine whether genetic variation in susceptibility to Porcine Respiratory and Reproductive Syndrome virus (PRRSV) exists. One hundred pigs from each of two distinctly different populations (NE Index Line, I, and Duroc-Hampshire cross pigs, DH) were challenged with PRRSV at 26 days old. A littermate to each challenged pig was included in the experiment without PRRSV challenge to serve as a control. Body weight and temperature were recorded and blood samples were drawn from all pigs on the day of challenge and 4, 7 and 14 days post-challenge. All pigs were sacrificed and a necropsy was performed …

Manure incorporation represents a compromise between best management practices for soil erosion control and manure management. Manure should be incorporated into the soil for odor control, increased availability of nutrients, and control of potential manure runoff. However, soil and crop residue disturbance should be minimized for soil erosion control. Values to estimate the amount of residue cover that will remain following the use of common manure application/incorporation components have been presented in the article titled “Crop Residue Cover and Manure Incorporation — Part I: Reduction of Cover.” This article discusses some of the influence that injector/ applicator spacing, tire spacing, …

Thermal Conditions Within Pens Fitted With Differing Zone-Heating Options And Resulting Performance Of Newly Weaned Pigs In A Wean-To-Finish Facility, Richard R. Stowell, Sherri Colgan, Mike Brumm
Nebraska Swine Reports
Research was conducted to assess the effects of the type of zone heater and floor mat used in a wean-to-finish building on the thermal environment created for newly weaned pigs and resulting pig performance. Gas-fired brooder heaters were compared to electric heat lamps and farm-cut wood sheathing was compared to commercial [unheated] rubber floor mats. No consistent differences in air temperature near the heating zone were found between either of the treatments. However, black-globe temperatures in pens having gas-fired heaters and/or wood mats were consistently warmer than in their comparison pens. Temperature deviations during the 26-day study period were similar …
