The Use Of Real-Time Ultrasound To Model The Growth Performance And Lysine Requirements Of Growing-Finishing Pigs On Commercial Farms, J W. Smith Ii, A P. Schinckel, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Eighty pigs, 40 barrows and 40 gilts, on two commercial finishing operations were used to model growth and accretion rates. Major differences were observed between the two farms. This analysis indicates that realtime ultrasound can be used to develop lean and lipid accretion curves for formulating farm-specific diets that optimize lean growth performance in commercial operations.; Swine Day, Manhattan, KS, November 21, 1996


Omitting Vitamin And Trace Mineral Premixes, And(Or) Reducing Inorganic Phosphorus During Late Finishing Did Not Affect Growth Performance, Carcass Traits, Or Muscle Quality, I Mavromichalis, Donald H. Kropf, G A. Kennedy, Robert H. Hines, B W. Senne, I H. Kim, S L. Johnston, Joe D. Hancock Jan 1996

Omitting Vitamin And Trace Mineral Premixes, And(Or) Reducing Inorganic Phosphorus During Late Finishing Did Not Affect Growth Performance, Carcass Traits, Or Muscle Quality, I Mavromichalis, Donald H. Kropf, G A. Kennedy, Robert H. Hines, B W. Senne, I H. Kim, S L. Johnston, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Omitting the vitamin and trace mineral premixes and(or) adding 2/3 less supplemental inorganic phosphorus source (from .55% down to .40% total P) to diets during late finishing (191 to 265 lb) had no effect on growth performance, carcass characteristics, or muscle quality in high-lean pigs. Thus, this concept can be used to decrease the cost of feeding terminal-cross pigs to heavy weights, while decreasing excretion of minerals from intensive swine operations.; Swine Day, Manhattan, KS, November 21, 1996


Evaluation Of Various Specialty Protein Sources As Replacements For Spray-Dried Animal Plasma In Diets For Segregated Early-Weaned Pigs, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, J W. Smith Ii, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1996

Evaluation Of Various Specialty Protein Sources As Replacements For Spray-Dried Animal Plasma In Diets For Segregated Early-Weaned Pigs, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, J W. Smith Ii, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We used high-health status, weanling pigs to evaluate six different protein sources as replacements for spray-dried animal plasma. Spray-dried blood meal, spray-dried egg, spray-dried wheat gluten, extruded soy protein concentrate, select menhaden fish meal, and soybean meal each replaced 2.5 or 5.0% spray-dried animal plasma. Pigs fed increasing levels of spray-dried blood meal, spray-dried egg, or soybean meal had decreased ADFI; however, increasing levels of select menhaden fish meal, extruded soy protein concentrate, and spray-dried wheat gluten had no influence or increased ADFI. For the high-health pigs used in this trial, select menhaden fish meal, extruded soy protein ...


Dietary Lysine Requirement For Optimal Growth Performance And Carcass Characteristics Of Late Finishing Gilts, J A. Loughmiller, I H. Kim, J C. Woodworth, J W. Smith Ii, J R. Bergstrom, K Hongtrakul, W B. Nessmith, R E. Musser, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach Jan 1996

Kansas Agricultural Experiment Station Research Reports

In Exp. 1, increasing dietary lysine from .40% to .70% linearly improved ADG, F/G, 10th rib fat depth, and percentage lean in finishing gilts from 200 to 250 lb. Increasing dietary lysine also tended to improve longissimus muscle area. Results from Exp. 2 indicate no improvement in growth or carcass performance of gilts fed greater than .60% lysine. The combined results of Exp. 1 and 2 indicate that finishing gilts from 200 to 250 lb requires between .60% to .70% (18 to 20 g/d) dietary lysine to maximize both growth performance and carcass characteristics.; Swine Day, Manhattan, KS ...


Removing Vitamin And Trace Mineral Premixes From Finisher Diets (154 To 247 Lb) Did Not Affect Growth Performance, Carcass Characteristics, Or Meat Quality, I H. Kim, J H. Lee, J S. Park, Donald H. Kropf, S L. Johnston, P Sorrell, Robert H. Hines, Joe D. Hancock Jan 1996

Removing Vitamin And Trace Mineral Premixes From Finisher Diets (154 To 247 Lb) Did Not Affect Growth Performance, Carcass Characteristics, Or Meat Quality, I H. Kim, J H. Lee, J S. Park, Donald H. Kropf, S L. Johnston, P Sorrell, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Average daily gain; ADFI; F/G; dressing percentage; tenth rib fat thickness and depth; and color, firmness, and marbling of the longissimus muscle were not influenced by omitting the vitamin and(or) trace mineral premixes from diets during finishing (154 to 247 lb). Thus, omitting vitamin and trace mineral premixes can decrease diet costs without decreasing performance or meat quality of high-lean pigs.; Swine Day, Manhattan, KS, November 21, 1996

Explaining Differences In Efficiency Among Farrow-To-Finish Producers, W W. Rowland, Michael R. Langemeier, Allen M. Featherstone, Bryan W. Schurle

Kansas Agricultural Experiment Station Research Reports

To remain competitive, hog operations will need to continue to improve production efficiency and manage costs. Kansas Farm Management Association data from 1992 to 1994 were used to measure technical, economic, and overall efficiency for 43 farrow-to-finish operations in Kansas. On average, the farms had .89 technical, .75 economic, and .67 overall efficiencies. Efficiency was related positively to the number of litters produced and pounds of pork produced per litter. Efficiency was related negatively to percentage of labor hired, feed conversion rates, and capital investment per litter. Pounds of pork produced per litter and feed conversion had the largest impacts ...

Survey Of Pork Products Available To Consumers, S Hollinger, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

A survey was conducted to investigate the variety and price per pound of pork products available to consumers. The survey was conducted in the largest store of each of the three leading supermarket chains in Manhattan, KS. The 217.3 pork products per store (642 total) were categorized into fresh pork, smoked/cured pork, sausages, lunch meats, and pastry/pork combinations, which represented 7.4, 13.9, 32.5, 20.4, and 24.4% of the pork products surveyed, respectively. Retail cuts from the loin were the most numerous and highest priced in the fresh pork category. Retail cuts from ...

Effects Of High Oil Corn And Fat Level On Growth Performance Of Nursery Pigs, J R. Bergstrom, C J. Samland, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband Jan 1996

Effects Of High Oil Corn And Fat Level On Growth Performance Of Nursery Pigs, J R. Bergstrom, C J. Samland, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Two studies were conducted to evaluate the effects of adding high oil corn to nursery diets as compared to other sources of fat. The results of both studies suggest that addition of fat to the nursery pig diet, regardless of the source, has no significant influence on growth performance until late in the nursery phase.; Swine Day, Manhattan, KS, November 21, 1996


The Effects Of Porcine Reproductive And Respiratory Syndrome (Prrs) Vaccination On Postweaning Growth Performance, S D. Pretzer, K M. Claussen, J R. Bergstrom, Steven C. Henry, R Phillips, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1996

Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of a modified-live virus vaccine for PRRS virus on nursery growth performance. The pigs used in this study were obtained from a herd with substandard nursery growth performance attributed to PRRS virus infection. We failed to detect the presence of active circulating field strain virus in either the controls or vaccinated pigs. However, we did detect a strain similar to the vaccine virus strain on d 34 after weaning in the vaccinated pigs. The vaccinated pigs had poorer growth performance from d 7 to 14 after vaccination and were lighter in weight for the remainder of ...


Effect Of Dietary L-Carnitine On Growth, Carcass Characteristics, And Metabolism Of Swine, K Q. Owen, H Ji, C V. Maxwell, G C. Tremblay, S I. Koo, S A. Blum, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach Jan 1996

Kansas Agricultural Experiment Station Research Reports

Thirty six Yorkshire gilts (initially 123 lb BW) were used to investigate the effect of dietary carnitine on growth performance, carcass characteristics, fatty acid oxidation, and enzyme kinetics. Dietary carnitine reduced fat deposition in favor of protein deposition, stimulated fatty acid oxidation, induced the expression of pyruvate carboxylase, increased the capacity of pyruvate carboxylase flux, and decreased the capacity of branch chain keto-dehydrogenase.; Swine Day, Manhattan, KS, November 21, 1996


Influence Of Pellet Size On Growth Performance In Nursery Pigs And Growth Performance, Nutrient Digestibility, And Stomach Morphology In Finishing Pigs, S L. Traylor, Keith C. Behnke, P Sorrell, Fred J. Fairchild, Robert H. Hines, Joe D. Hancock Jan 1996

Influence Of Pellet Size On Growth Performance In Nursery Pigs And Growth Performance, Nutrient Digestibility, And Stomach Morphology In Finishing Pigs, S L. Traylor, Keith C. Behnke, P Sorrell, Fred J. Fairchild, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Pellet size (i.e., 3/32 in., 5/32 in., 5/16 in., and 1/2 in. diameter) had little effect on growth performance during the early stages (d 0 to 5) of the nursery phase. However, the 5/32 in. diameter pellets supported the best efficiencies of gain during the overall nursery (d °to 29) and finishing phases.; Swine Day, Manhattan, KS, November 21, 1996

Determining The Optimal Isoleucine:Lysine Ratio In Diets For The Segregated Early-Weaned Pig, J R. Bergstrom, J A. Loughmiller, R E. Musser, W B. Nessmith Jr, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz Jan 1996

Determining The Optimal Isoleucine:Lysine Ratio In Diets For The Segregated Early-Weaned Pig, J R. Bergstrom, J A. Loughmiller, R E. Musser, W B. Nessmith Jr, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A 14-d growth trial was conducted to evaluate effects of increasing isoleucine: lysine ratios on growth performance of the segregated early-weaned pig. Twelve experimental diets included two levels of lysine (1.15%and 1.50% digestible lysine) and six digestible isoleucine: lysine ratios (40, 45,50, 55, 60, and 65% relative to lysine) in a 2 x 6 factorial arrangement. From d 0 to 14, growth performance was improved by feeding 1.50% digestible lysine. A linear improven1ent in growth performance occurred from d 0 to 7 as the isoleucine:lysine ratio increased. Although a significant quadratic response was not ...


Effects Of Added Choline On Performance Of Weanling Pigs, K Hongtrakul, I H. Kim, J A. Loughmiller, J W. Smith, H Cao, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen Jan 1996

Effects Of Added Choline On Performance Of Weanling Pigs, K Hongtrakul, I H. Kim, J A. Loughmiller, J W. Smith, H Cao, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A 28-d growth assay was conducted to determine the effects of added choline on weanling pig performance. Pigs were fed a control diet without added choline or diets containing 150 g/ton of added choline. No differences in pig growth performance were observed. These results suggest that added choline can be removed from weanling pig diets.; Swine Day, Manhattan, KS, November 21, 1996


The Effects Of Dietary Energy Density And Lysine:Calorie Ratio On The Growth Performance Of The 20 To 55 Lb Pig, J W. Smith Ii, W B. Nessmith Jr, J R. Bergstrom, K Hongtrakul, J A. Loughmiller, R E. Musser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen Jan 1996

Kansas Agricultural Experiment Station Research Reports

A 21-day growth trial was conducted to determine the effect of various carbohydrate sources with or without moist extrusion processing on growth performance of segregated early-weaned pigs. Treatments included five different carbohydrate sources (corn, corn starch, rice, wheat flour, and grain sorghum) with or without moist extrusion processing in a 2 x 5 factorial arrangement. No interactions were observed among carbohydrate sources and extrusion processing. Growth performance was not improved by extrusion processing. Surprisingly, pigs fed corn had poorer growth performance compared to those fed other carbohydrate sources. These results suggest that corn starch, rice, wheat flour, and grain sorghum ...


Evaluation Of The Total Sulfur Amino Acid Requirement Of Finishing Pigs, J A. Loughmiller, J W. Smith Ii, J R. Bergstrom, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen Jan 1996

Evaluation Of The Total Sulfur Amino Acid Requirement Of Finishing Pigs, J A. Loughmiller, J W. Smith Ii, J R. Bergstrom, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Sixty four gilts (initially 120 lb) were used to evaluate the effects of increasing total sulfur amino acid (TSAA):lysine ratios on growth performance and carcass characteristics. Diets included two levels of lysine (.55% and .70% total lysine) and three TSAA:lysine ratios (60, 65, and 70% of lysine) arranged in a 2 x 3 factorial. A tendency for a lysine x TSAA interaction was observed for ADG and ADFI. Increasing TSAA:lysine ratio decreased ADG and ADFI in pigs fed .55% lysine; however, ADG and ADFI were increased in pigs fed .70% lysine and 65% TSAA:lysine. Pigs fed ...


Swine Manure Management, James P. Murphy Jan 1996

Swine Manure Management, James P. Murphy

Kansas Agricultural Experiment Station Research Reports

Manure nutrients help build and maintain soil fertility. Manure also improves tilth, increases waterholding capacity, lessens wind and water erosion, improves aeration, and promotes beneficial organisms. When wastes include runoff or dilution water, they can supply water as well as nutrients to crops. The economic value of manure fertilizer is calculated from its available nitrogen (N), phosphorus (P), and potassium (K) at commercial fertilizer prices. These values change with the costs of fertilizer and handling practices.; Swine Day, Manhattan, KS, November 21, 1996


Dietary Total Sulfur Amino Acid Requirement For Optimal Growth Performance And Carcass Characteristics In Finishing Gilts, J A. Loughmiller, Michael D. Tokach, Evan C. Titgemeyer, I H. Kim, J R. Bergstrom, J W. Smith Ii, Robert D. Goodband, Jim L. Nelssen Jan 1996

Dietary Total Sulfur Amino Acid Requirement For Optimal Growth Performance And Carcass Characteristics In Finishing Gilts, J A. Loughmiller, Michael D. Tokach, Evan C. Titgemeyer, I H. Kim, J R. Bergstrom, J W. Smith Ii, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Finishing gilts (initially 163 lb) were fed .58% total lysine (.50% apparent digestible) and total sulfur amino acid (TSAA) concentrations of .26,.285, .31, .335, and .36% (.225 to .325% apparent digestible). These values represent TSAA: lysine ratios of 45, 50, 55, 60, and 65%. Results suggest a linear decrease in ADG and ADFI along with poorer F/G with increasing TSAA levels. However, gilts fed .285% TSAA (50% of lysine) had the best ADG and F/G. No effect was observed on any carcass criteria. Based on the results of this study, the TSAA requirement is not greater than ...

Effects Of Fat And Sodium Bicarbonate On Growth Performance And Stomach Morphology In Finishing Pigs, S P. Sorrell, I H. Kim, Robert H. Hines, G A. Kennedy, L L. Burnham, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Pigs fed diets with soybean oil consumed less feed; grew more efficiently; and had greater last-rib backfat thickness, keratosis, and ulceration in their stomachs than pigs fed diets without soybean oil. Pigs fed diets with NaHC03 tended to eat more feed and had numerically greater ADG, but feed/gain and carcass measurements were not affected. NaHC03 decreased ulceration scores only for pigs fed diets without added fat.; Swine Day, Manhattan, KS, November 21, 1996


Influence Of Lysine Concentration On Growth Performance And Carcass Characteristics Of Finishing Pigs, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz Jan 1996

Influence Of Lysine Concentration On Growth Performance And Carcass Characteristics Of Finishing Pigs, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We used a total of 11,653 pigs to examine the influence of a lysine phase-feeding regimen on growth performance and carcass characteristics in finishing pigs. We found that the lysine regimen did not affect ADG. Also, the low-lysine regimen was adequate for maximizing growth performance and carcass characteristics of barrows. However, the low-lysine regimen was inadequate to optimize feed efficiency in gilts. Further analysis indicated that the largest differences in feed efficiency were for the 115 to 160 lb period in gilts. Later in the growth period, feed efficiency of gilts was similar across dietary lysine regimens.; Swine Day ...


Effects Of Expanders (High Shear Conditioning) On Growth Performance In Finishing Pigs, S L. Johnston, S L. Traylor, Robert H. Hines, S P. Sorrell, I H. Kim, G A. Kennedy, Joe D. Hancock, Keith C. Behnke Jan 1996

Effects Of Expanders (High Shear Conditioning) On Growth Performance In Finishing Pigs, S L. Johnston, S L. Traylor, Robert H. Hines, S P. Sorrell, I H. Kim, G A. Kennedy, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Diets that had been processed using standard, long-term, and expander (high shear) conditioning tended to support greater ADG than an unconditioned meal control diet. Pelleting was necessary to maximize efficiency of growth, but only with standard and long-term conditioning. Indeed, the best efficiencies of gain were for pigs fed the expander processed diets, with no additional benefits from pelleting the expanded mash.; Swine Day, Manhattan, KS, November 21, 1996


Use Of Sorghum-Based Distillers Grains In Diets For Nursery And Finishing Pigs, B W. Senne, I Mavromichalis, S L. Johnston, P S. Sorrell, I H. Kim, Robert H. Hines, Joe D. Hancock Jan 1996

Use Of Sorghum-Based Distillers Grains In Diets For Nursery And Finishing Pigs, B W. Senne, I Mavromichalis, S L. Johnston, P S. Sorrell, I H. Kim, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to etermine the effects of sorghum-based distillers dried grains with solubles in isocaloric diets for nursery and finishing pigs. Rate and efficiency of gain in nursery pigs were decreased with 45% or more distillers grains. For finishing pigs, efficiency of gain was improved as distillers grains was increased to 60% of the diet, and carcass fatness was increased by about .1 inch at the highest concentration.; Swine Day, Manhattan, KS, November 21, 1996


Effects Of Antibiotics On Shedding Of Salmonella Typhimurium In Experimentally Inoculated Pigs, D R. Hyatt, J C. Galland, Jerome C. Nietfeld, C Irwin, C Davison, Steven S. Dritz Jan 1996

Effects Of Antibiotics On Shedding Of Salmonella Typhimurium In Experimentally Inoculated Pigs, D R. Hyatt, J C. Galland, Jerome C. Nietfeld, C Irwin, C Davison, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

The objective of this experiment was to determine if antibiotics used as feed additives and disease treatment for livestock affect duration of shedding and colonization of tissues with Salmonella typhimurium in pigs. No statistically significant difference was detected in duration or amount of shedding of S. typhimurium between pigs receiving antibiotics and control pigs. Antibiotics prevented colonization of tissues by S. typhimurium. The odds (OR= .02) of isolating S. typhimurium in at least one of four tissues examined were significantly less from pigs treated with antibiotics than from control pigs (two-tailed Fisher exact test, P= .009).; Swine Day, Manhattan, KS ...


Evaluation Of Spray-Dried Cheese Food As A Supplemental Protein Source For Weanling Pigs, J A. Loughmiller, P S. Graf, J R. Bergstrom, R E. Muser, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz Jan 1996

Evaluation Of Spray-Dried Cheese Food As A Supplemental Protein Source For Weanling Pigs, J A. Loughmiller, P S. Graf, J R. Bergstrom, R E. Muser, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A growth study was conducted to determine the effects of substituting spray-dried cheese food for spray-dried plasma protein on weanling pig performance. Five dietary treatments included the control diet or diets with cheese food replacing 25, 50, 75, and 100% of the plasma on an equal lysine basis. Day 0 to 14 ADG and ADFI were decreased linearly as spray-dried cheese food increased. However, this decrease was most apparent when cheese food was included at more than 4% of the diet. No effects of cheese food inclusion were seen for F/G from d 0 to 14 postweaning or for ...


Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance, E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 1996

Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance, E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

High producing sows were used to evaluate the effect of spray-dried blood cells as a dietary protein source on lactation performance and subsequent reproductive performance. No significant differences were observed between sows fed a corn-soybean cells-based diet or a diet containing 2.5% spray-dried blood cells for lactation performance or subsequent reproductive performance. Therefore, spray-dried blood cells can be used as a partial replacelnent for the protein source in lactation diets.; Swine Day, Manhattan, KS, November 21, 1996


Determining The Optimal Threonine:Lysine Ratio In Starter Diets For The Segregated Early-Weaned Pig, J R. Bergstrom, W B. Nessmith Jr, C A. Civis, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband Jan 1996

Kansas Agricultural Experiment Station Research Reports

A 14-day growth trial was conducted to determine the threonine: lysine ratio necessary to optimize growth performance of the segregated early-weaned (SEW) pig. Twelve experimental diets included two levels of lysine (1.15% and 1.5% apparent digestible lysine) and six apparent digestible threonine: lysine ratios (40, 45, 50, 55, 60, and 65 %) in a 2 x 6 factorial arrangement. Growth performance was improved by feeding 1.5% rather than 1.15% digestible lysine. Growth performance decreased linearly as the digestible threonine: lysine ratio increased. Although a significant quadratic response was not observed, this reduction in growth performance did not ...


Influence Of A Probiotic/Trace Mineral Mixture On Growth Performance And Salmonella Choleraesuis Shedding In Nursery Pigs, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz Jan 1996

Influence Of A Probiotic/Trace Mineral Mixture On Growth Performance And Salmonella Choleraesuis Shedding In Nursery Pigs, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We tested a probiotic/trace mineral mixture using a bacterial challenge model in high-health status pigs. We examined the influence of the mixture on growth performance, hematologic parameters, haptoglobin concentration, and Salmonella choleraesuis shedding in nursery pigs. A successful model of S. cholereasuis challenge was established. However, the probiotic/trace mineral mixture did not influence growth performance, bacterial shedding, or other parameters examined in this experiment.; Swine Day, Manhattan, KS, November 21, 1996
