Comparison Of Gleptosil With Iron Dextran For Anemia Prevention In Young Pigs (1982), D S. Pollmann, J E. Smith, Jeffrey S. Stevenson, D A. Schoneweis, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Gleptosil, a commercial iron product, was compared with iron dextran for the prevention of iron deficiency anemia in young pigs. Using 26 litters, pigs (within each litter) were randomly allotted to one of the three treatments: 1) control (no iron), 2) iron dextran (200 mg) and 3) Gleptosil (2OO mg). Blood was collected at 0, 10, 21 and 50 days post-treatment for red blood cell count (RBC), hematocrit (HCT), hemoglobin (HGB) concentration, serum iron concentration and serum iron-binding capacity (IBC). At 21 days, 30 pigs (one pig/treatment from each of 10 litters) were killed to determine mg non-heme iron (NHFe) …

Kansas Agricultural Experiment Station Research Reports
KSU breeding records show a higher farrowing rate for gilts that "lock" on the insemination spirette at both inseminations as opposed to gilts that "lock" at one insemination or at neither insemination. Continued research is focusing on factors affecting female response to insemination and fertility.; Swine Day, Manhattan, KS, November 11, 1982
Value Of Rhinitis Vaccination Of Young Pigs (1982), D S. Pollmann, D A. Schoneweis, G A. Kennedy
Value Of Rhinitis Vaccination Of Young Pigs (1982), D S. Pollmann, D A. Schoneweis, G A. Kennedy
Kansas Agricultural Experiment Station Research Reports
A study was conducted using 57 pigs from 10 litters to evaluate the value of rhinitis vaccination on performance, carcass quality, and health status. Pigs vaccinated with bordetella vaccine had fewer (P<.05) days to market and weight gains were superior (P<.05) to the non-vaccinated control group. Carcass quality and turbinate atrophy were not different among treatments. Turbinate scores were not related to growth rate.; Swine Day, Manhattan, KS, November 11, 1982

Repopulation Of Pseudorabies-Infected Swine Herds By Embryo Transfers (1982), J E. James, D M. James, P A. Martin, Duane L. Davis
Kansas Agricultural Experiment Station Research Reports
Embryos were transferred from two pseudorabies infected herds to recipients from a pseudorabies free herd. All 38 donor sows had serum titers for pseudorabies but no recipients or pigs that were farrowed had clinical signs or serum titers for pseudorabies. In total 805 embryos were transferred to 34 recipient sows and gilts of which 22 (65%) farrowed 208 pigs (189 farrowed alive).; Swine Day, Manhattan, KS, November 11, 1982
Evaluation Of Flavomycin In On-Farm Trials (1982), D S. Pollmann, D Simms, E Francis, T Orwig, F Brazle
Evaluation Of Flavomycin In On-Farm Trials (1982), D S. Pollmann, D Simms, E Francis, T Orwig, F Brazle
Kansas Agricultural Experiment Station Research Reports
Twelve on-farm trials with a total of 1572 pigs were conducted to evaluate the effect of Flavomycin in growing-finishing swine diets. In three of the twelve trials, average daily gain was increased (P<.06) and in seven of the trials, feed efficiency was improved numerically with Flavomycin over nonmedicated control and other feed additives (Aureomycin, Tylan, Stafac, Pen-Strep, and Lincomix). The percent improvement varied greatly by location of the trial.; Swine Day, Manhattan, KS, November 11, 1982
Hard Wheat Compared To Soft Wheat For Finishing Swine (1982), Robert H. Hines
Hard Wheat Compared To Soft Wheat For Finishing Swine (1982), Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Three feeding trials were conducted to compare soft winter wheat with hard winter wheat for finishing swine. In each trial, soft wheat diets supported weight gains and feed/gain ratio equal to those observed for pigs fed hard winter wheat diets. Both soft and hard wheat diets were compared with milo basal diets resulting in similar performances and reaffirming that wheat can replace all the milo in a swine diet. The study involving the method of processing the wheat diets indicated that rolled wheat diets resulted in pig performance superior to ground diets. Pelleting wheat diets was superior to both grinding …
Growing Vegetables And Flowering Plants In A Greenhouse Supplied With Swine-Building Exhaust Air (1982), J K. Greig, C K. Spillman, B A. Koch
Growing Vegetables And Flowering Plants In A Greenhouse Supplied With Swine-Building Exhaust Air (1982), J K. Greig, C K. Spillman, B A. Koch
Kansas Agricultural Experiment Station Research Reports
Exhaust air from a Kansas State University swine-farrowing house provides CO2 and possibly other gases that are being used by vegetable plants in a KSU greenhouse. In addition, a rock-storage system reduces fuel requirements of the greenhouse. Tomatoes and cucumbers have been the major food crops studied, but transplant production of geraniums, marigolds, snapdragons, and calendula also has been studied. Poinsettias were grown as a fall crop in 1980 and again in 1982.; Swine Day, Manhattan, KS, November 11, 1982

Kansas Agricultural Experiment Station Research Reports
Two studies were designed to test the effects of stunning method and time interval between stunning and bleeding on blood splashing in pork muscle. In study I, 82 market weight barrows and gilts were randomly assigned to one of two treatments using captive bolt stunning with either a short (18.5 sec) or a delayed (144.7 sec) time interval to bleeding. More (P.05) for the captive bolt-short, electric-short and electric-delayed time groups.; Swine Day, Manhattan, KS, November 11, 1982
Effect Of Test Weight Of Hard Winter Wheat On Performance Of Finishing Swine (1982), D S. Pollmann, Robert H. Hines
Effect Of Test Weight Of Hard Winter Wheat On Performance Of Finishing Swine (1982), D S. Pollmann, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Ninety crossbred pigs averaging 135 lbs. were used to evaluate the effect of reduced bushel weight of wheat on performance. Wheat (59 lb) fed to finishing pigs resulted in growth and feed efficiency similar to a milo base diet. Wheat of reduced bushel weight (51 lb and 45 lb) caused a linear effect upon feed efficiency because the pigs consumed more feed per day with equal average daily gain. The blending of equal parts of milo and 45 lb wheat resulted in similar growth rate and a slightly improved feed:gain ratio as compared to the pigs fed the 45 lb …
Varying Amounts Of Scabby Wheat Added To Growing-Finishing Rations (1982), B A. Koch, D S. Pollmann
Varying Amounts Of Scabby Wheat Added To Growing-Finishing Rations (1982), B A. Koch, D S. Pollmann
Kansas Agricultural Experiment Station Research Reports
Scabby wheat, infected with the fungus, Fusarium graminearum and grading No.4, replaced varying percentages of grain in a typical sorghum grain-soybean meal growing-finishing ration. Four pigs eating the control ration made an average daily gain of 1.91 pounds per day and a feed efficiency of 3.44. When 25% of the sorghum grain was replaced by scabby wheat, average daily gain dropped to 1.71 pounds per day and feed efficiency was 3.29. Replacing 50% of the sorghum grain with scabby wheat reduced average daily gain to 1.56 pounds with a feed efficiency of 2.99. Higher percentages of scabby wheat reduced feed …

Birth Sequence And Its Effects On Litter Size (1982), J D. Wheat, M S. Suba, G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Average farrowing interval and duration were 15.8 and 143.8 minutes for 1766 pigs born in 169 litters. Pigs born later in the litter were larger (r=.43) at birth. The correlation was -.14 between farrowing interval, average time between the birth of pigs within the litter, and litter 21-day weight. Sixteen pigs were classified as mummies and their birth sequences ranged from 1 to 15 with an average of 6.5. In 53.5 percent of the litters, the first pig born was a gilt and in 18.4 percent of the litters the first pig born was the largest in the litter. However, …
Influence Of Supplemental Light On Sow Performance During And After Lactation (1982), Jeffrey S. Stevenson, D S. Pollmann, Duane L. Davis, James P. Murphy
Influence Of Supplemental Light On Sow Performance During And After Lactation (1982), Jeffrey S. Stevenson, D S. Pollmann, Duane L. Davis, James P. Murphy
Kansas Agricultural Experiment Station Research Reports
A study involving 327 crossbred sows was conducted to determine whether providing supplemental light in farrowing rooms would influence litter weight, number of pigs weaned, piglet survival rate, and subsequent rebreeding performance of sows exposed to 16 hr supplemental light/day during lactation. Litter weight was increased 7.7 lbs or .85 lb per pig weaned. More sows exposed to 16 hr light (83%) were mated by 5 days after weaning than were control sows (68%).; Swine Day, Manhattan, KS, November 11, 1982
Eleven-Year Summary Of Ksu On-Farm Swine Testing Program (1982), David A. Nichols, D S. Pollmann, W G. Olson

Kansas Agricultural Experiment Station Research Reports
Records of approximately 11,000 boars and 6,000 gilts enrolled in the KSU on-farm swine test program were summarized. Both boars and gilts reached 220 lbs 5 days sooner in 1980 than 1970. Of the traits evaluated, the largest improvement was a reduction in backfat thickness of 25% from 1970 to 1980. Loin-eye area increased from 1970 to 1975 but declined from 1975 to 1980.; Swine Day, Manhattan, KS, November 11, 1982
Sorghum Grain Stillage For Pregnant Gilts (1982), G L. Allee, B A. Koch, K Jackson
Sorghum Grain Stillage For Pregnant Gilts (1982), G L. Allee, B A. Koch, K Jackson
Kansas Agricultural Experiment Station Research Reports
Gilts during pregnancy consumed approximately 29 pounds of milo stillage per day, when fed only stillage. Availability of water did not affect stillage consumption. Gilts fed stillage consumed only 2.2 pounds of DM per day which was not enough to maintain body weight. Gilts fed all the stillage they would consume and one pound of the control diet made similar weight gains and had similar reproductive performance as gilts fed three pounds of the control diet. This suggests that the energy value of the milo stillage is similar to that of the control diet (1620 kcal DE/lb DM) for gilts …
Effect Of Particle Size And Physical Form On Digestibility Of Sun-Cured Alfalfa For Pregnant Sows (1982), L J. Nuzback, D S. Pollmann, Keith C. Behnke
Effect Of Particle Size And Physical Form On Digestibility Of Sun-Cured Alfalfa For Pregnant Sows (1982), L J. Nuzback, D S. Pollmann, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
Sixteen pregnant crossbred sows (second parity) were employed in a digestion trial to evaluate the effect of particle size and physical form of sun-cured alfalfa. The treatment consisted of 1/4 inch meal, 1/4 inch pelleted, 1/2 inch meal, and ½ inch meal pelleted. Utilization of dry matter (DM), digestible energy (DE) and fiber components increased (P<.05) with the 1/4 inch particle size compared to 1/2 inch. Nitrogen utilization was not affected by the two particle sizes. Cellulose digestibility increased (P<.05) when pelleted but other digestion coefficients were not affected. During the third trimester, digestibility of DM, energy and fiber components increased (P<.05) compared to the first trimester. Apparent nitrogen digestibility increased (P<.05) in the third trimester but nitrogen balance and nitrogen retention decreased. The results of this study indicate that alfalfa is equally digested as meal or pellets and increased utilization by gestating sows can be expected with decreased particle size.; Swine Day, Manhattan, KS, November 11, 1982

Kansas Agricultural Experiment Station Research Reports
We compared mating performance and soundness of feet and legs of boars which were reared in group vs individual pens. Individually penned boars consumed more feed from 6 to 12 weeks of age and were heavier at 12 weeks of age. However, individually penned boars also were more unsound and tended to score lower in mating tests.; Swine Day, Manhattan, KS, November 11, 1982
Big Things - Little Things (1982), D D. Pretzer
Big Things - Little Things (1982), D D. Pretzer
Kansas Agricultural Experiment Station Research Reports
This study examined the economic effects of applying controllable management factors for farrow-to-finish operations. Average producers in Kansas market 7 pigs/litter with an average feed conversion of 4.58. Improvement in 9 areas of management increased profits on 240 litters by $43,680. Each item appears small. However "Big Things" come from the sum of "Little Things".; Swine Day, Manhattan, KS, November 11, 1982

Economics, Veterinary Service And Herd Health Programs (1982), Steven C. Henry
Kansas Agricultural Experiment Station Research Reports
Among the many changes in the swine industry during the past two decades, the concept of "Herd Health Programs" came to be. Still a buzz word with poorly defined activities, "Herd Health Programs" are part of our industry. Just listen in the halls during producer or veterinary meetings -- we discuss getting one, already having one, offering one, getting into the business of delivering several of them -- and none of us is quite sure what "one" is and, most of all, what it's worth. There should be no surprise that neither of us, producer or veterinarian, really has the …

Effects Of Whey Products On Performance Of Weaned Pigs (1982), S Pope, G L. Allee
Kansas Agricultural Experiment Station Research Reports
Three trials were conducted utilizing 458 pigs with an average age of 21 days to study the effects of adding whole whey, or partially delactosed whey from two sources in the diet of weaned pigs on growth, feed intake, and feed efficiency. Additionally, the optimum length of time to feed whole whey and the relationship of age at weaning and addition of whey to the diet were studied. The addition of whey to the diets increased performance of the pigs by 2 to 3 pounds at 8 weeks of age. Pigs fed 20% whole whey diets for 2 weeks performed …

Value Of Sprinklers To Reduce Heat Stress Of Lactating Sows (1982), David A. Nichols, James P. Murphy, D S. Pollmann, D R. Ames
Kansas Agricultural Experiment Station Research Reports
Twenty-eight sows and gilts were used to evaluate the value of drip sprinkling to reduce heat stress during lactation. Sprinkled sows had significantly lower respiration rates (P<.05) and consumed significantly more feed during the 21-day lactation. Number of pigs born live, dead, and weaned were not affected by sprinkling. Sprinkled sows tended to wean heavier pigs and lose less weight during lactation but these differences were not significant. These results indicate that a drip cooling for lactating sows is a low cost, effective method to reduce heat stress.; Swine Day, Manhattan, KS, November 11, 1982
Effects Of Limit-Feeding Finishing Swine On Performance And Carcass Measurements (1982), W Zook, G L. Allee
Effects Of Limit-Feeding Finishing Swine On Performance And Carcass Measurements (1982), W Zook, G L. Allee
Kansas Agricultural Experiment Station Research Reports
Two feeding trials with 138 crossbred pigs with an average initial weight of 129 pounds were conducted to determine the effects of limit feeding on average daily gain, feed efficiency and carcass measurements. Pigs were fed either ad libitum, restricted to 80 or 85% of ad Iibitum intake, or restricted to 2, 4 or 8 hours access to self-feeders. Average daily gain was decreased (P<.05) by reducing feed intake to 80 or 85% of ad Iibitum, and restricting pigs to 2, or 4 hours access to feed. Pigs allowed 8 hours access to feed gained at the same rate, with similar feed intake as pigs fed ad Iibitum. Feed efficiency was not different for any of the restricted fed treatments. However, pigs restricted to 80% of ad Iibitum had the best feed efficiency. Barrows and gilts responded similarly to restricted feeding.; Swine Day, Manhattan, KS, November 11, 1982

Effect Of Scabby Wheat In Starter Pig Diets (1982), D S. Pollmann, B A. Koch
Kansas Agricultural Experiment Station Research Reports
Two studies using a total of 64 starter pigs (averaging 16-18 lbs initial weight) to evaluate the influence of varying levels of vornitoxin-contaminated wheat on performance was conducted. In both trials it appears that when vomitoxin levels exceed 1 ppm, a reduction in performance was evident. Feed refusal was evident particularly the first week on the vomitoxin-contaminated wheat. No symptoms of sickness, nor an influence on tissue size and function, were observed. The pigs were unable to compensate for depression in gains after withdrawal of vomitoxin-contaminated wheat.; Swine Day, Manhattan, KS, November 11, 1982

Stability Of Commercially Available Lactobacillus Products (1982), D S. Pollmann, C A. Bandyk
Kansas Agricultural Experiment Station Research Reports
A study was conducted to determine the viability of three commercially available lactobacillus products in nonmedicated and medicated (lincomycin at 100 grams per ton) swine feed in several different environments over a 3-month period. Each product was stored in five environments: refrigeration (40°F), room temperature (70°F) in sealed container, room temperature in unsealed container, swine nursery (90°F) in a sealed container, and swine nursery in an unsealed container. Feed samples were counted for lactobacillus at weeks 0, 1, 3, 5, 7, and 12 with four replications. The three commercial products differed in stability while maintained in the various environmental conditions. …
Lysine And Dried Whey Additions In Starter Pig Diets (1982), D S. Pollmann, G A. Allee, Robert H. Hines
Lysine And Dried Whey Additions In Starter Pig Diets (1982), D S. Pollmann, G A. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
A total of 943 newly weaned (18 to 30 days of age) pigs were used in five trials to evaluate the addition of lysine and dried whey in starter diets. The results of these studies show that the lysine requirement is 1.2 to 1.3% during the nursery phase (up to approximately 50 lbs). When lysine levels are greater than 1.3% with added L-Iysine monohydrochloride, a reduction in performance will be evident (P<.05). Rolled dried whey appears to be inferior (P<.10) to spray dried whey in starter pig diets.; Swine Day, Manhattan, KS, November 11, 1982

Pregnant Sow Behavior When Housed In Groups And Singly (1982), J V. Craig
Pregnant Sow Behavior When Housed In Groups And Singly (1982), J V. Craig
Kansas Agricultural Experiment Station Research Reports
Pregnant sow housing varies considerably from area to area in Australia. Thus, group housing amounts to less than 10% in Queensland, but probably exceeds 50% in Victoria. Confinement of pregnant sows in individual stalls is the most common alternative to group housing, but sows on some farms are separated from each other by tethers. When group housing is replaced by individual stalls or tethers, piggery managers often cite "bullying" of subordinate sows by dominant ones, especially during feeding, as a major problem leading to the change. Nevertheless, animal welfare proponents object to physical isolation of pregnant sows. McBride proposes that …
