The Effects Of Substituting Deproteinized Whey Or Pure Lactose For Dried Whey On Starter Pig Performance, W B. Nessmith Jr, J R. Bergstrom, J W. Smith Ii, K Q. Owen, J A. Loughmiller, R E. Musser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen Jan 1995

The Effects Of Substituting Deproteinized Whey Or Pure Lactose For Dried Whey On Starter Pig Performance, W B. Nessmith Jr, J R. Bergstrom, J W. Smith Ii, K Q. Owen, J A. Loughmiller, R E. Musser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A study was conducted to evaluate the effects of replacing all or half of spray-dried, edible-grade whey with deproteinized whey or pure lactose on starter pig performance. No differences in pig performance were observed. Therefore, high quality deproteinized whey and lactose are effective replacements for the lactose provided by dried whey in starter pig diets.; Swine Day, Manhattan, KS, November 16, 1995


Can Augers Be Used To Blend Diets On The Farm?, S L. Johnston, Robert H. Hines, S L. Traylor, Joe D. Hancock, Keith C. Behnke Jan 1995

Can Augers Be Used To Blend Diets On The Farm?, S L. Johnston, Robert H. Hines, S L. Traylor, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Growing/finishing gilts were fed two-, three-, four-, or five-phase diet regimens from 77 to 276 lb. The diets were mixed in either a conventional, horizontal ribbon mixer or a 9 ft auger. No interactions occurred among the mixer type and phase-feeding treatments. Pigs fed diets blended with the auger had similar ADG but slightly (4%) worse F/G compared to those fed diets mixed in the mixer. Finally, the three-phase regimen gave the lowest F/G and the lowest cost of gain.; Swine Day, Manhattan, KS, November 16, 1995


Mixing And Clean-Out Properties Of Sulfamethazine And Carbadox In Swine Feed, T Herrman, Keith C. Behnke, T Loughin Jan 1995

Mixing And Clean-Out Properties Of Sulfamethazine And Carbadox In Swine Feed, T Herrman, Keith C. Behnke, T Loughin

Kansas Agricultural Experiment Station Research Reports

Results of this study suggest that carbadox was incorporated uniformly in the feed by mixing. However, the two medicated feed additives containing sulfamethazine did not incorporate uniformly in the feed. The causal mechanism for the poor mixing performance of sulfamethazine was not discovered; however, assay variability was eliminated as a primary source of variation. Flushing the feed mixing, conveying, and sack-off systems twice with ground corn did not eliminate drug carryover. Further investigation of the mixing and clean-out properties of medicated feed additives is warranted.; Swine Day, Manhattan, KS, November 16, 1995


Effects Of Lactose Sources On Nursery Pig Growth Performance, W B. Nessmith Jr, J R. Bergstrom, J W. Smith Ii, K Q. Owen, B T. Richert, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband Jan 1995

Effects Of Lactose Sources On Nursery Pig Growth Performance, W B. Nessmith Jr, J R. Bergstrom, J W. Smith Ii, K Q. Owen, B T. Richert, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A study was conducted to evaluate different sources of pure lactose as a substitute for spray-dried, edible-grade whey in starter diets. Results suggest that pure lactose can replace the lactose provided by dried whey in phase I starter diets. However, numerical differences in growth performance occurred among the lactose sources used.; Swine Day, Manhattan, KS, November 16, 1995


Dietary Lysine And Slaughter Weight Affect Growth Performance And Carcass Characteristics In Boars And Barrows, M M. Rantanen, Robert H. Hines, I H. Kim, K G. Friesen, Joe D. Hancock Jan 1995

Dietary Lysine And Slaughter Weight Affect Growth Performance And Carcass Characteristics In Boars And Barrows, M M. Rantanen, Robert H. Hines, I H. Kim, K G. Friesen, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

During the growing and finishing period, the boars ate less, had better F/G, and were less fat than barrows. A high plane of nutrition (high vs moderate lysine concentrations for the growing-finishing phases) and decreasing slaughter weight from 260 to 220 lb also improved efficiency of gain and carcass leanness. However, many notable interactions occurred among the gender x lysine x slaughter weight treatments. Also, year (rotational-cross of average health status and lean growth potential vs a terminal-cross of high lean growth potential after repopulation of the farm) had pronounced effects on growth performance and carcass merits such that ...


Consumer Acceptance Of Low-Dose Irradiated, Boneless, Pork Chops, S E. Luchsinger, Zepeda C.M. Garcia, Edgar Iv Chambers, M E. Hollingsworth, Melvin C. Hunt, James L. Marsden, Sally L. Stroda, Canas E. Rubio J, Curtis L. Kastner, W G. Kuecker, T Mata, Donald H. Kropf Jan 1995

Consumer Acceptance Of Low-Dose Irradiated, Boneless, Pork Chops, S E. Luchsinger, Zepeda C.M. Garcia, Edgar Iv Chambers, M E. Hollingsworth, Melvin C. Hunt, James L. Marsden, Sally L. Stroda, Canas E. Rubio J, Curtis L. Kastner, W G. Kuecker, T Mata, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Acceptance of irradiated, chilled, boneless, pork chops and nonirradiated controls by consumers was not different. Coupled with consumer concerns about food safety and well-documented improvement in consumer attitudes about irradiated foods, the potential for market acceptance is very promising.; Swine Day, Manhattan, KS, November 16, 1995


Effects Of Dry-Extruded Whole Soybeans On Growth Performance Of Nursery Pigs And Growth Performance, Carcass Characteristics, And Stomach Morphology Of Finishing Pigs, I H. Kim, Robert H. Hines, L L. Burnham, Terry L. Gugle, Joe D. Hancock Jan 1995

Effects Of Dry-Extruded Whole Soybeans On Growth Performance Of Nursery Pigs And Growth Performance, Carcass Characteristics, And Stomach Morphology Of Finishing Pigs, I H. Kim, Robert H. Hines, L L. Burnham, Terry L. Gugle, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

In a 3 I-d nursery experiment, replacing soybean meal (SBM) with dry-extruded whole soybeans (DEWS) tended to improve F/G (6% overall difference), but ADG was not affected. Adjusting the diet with DEWS to the nutrient:calorie ratio of the diet with SBM did not greatly improve growth performance compared to the diet that was simply formulated to the same concentration of lysine as the diet with SBM. In a second experiment (with finishing pigs), 50 and 100% of the SBM in a corn-based diet was replaced with DEWS. Replacement resulted in 2% greater ADG and 8% better F/G ...


Influence Of Increased Vitamin Levels For The First 35 D Postweaning On Breeding And Subsequent Lactation Performance Of Sows, G Lynch, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 1995

Influence Of Increased Vitamin Levels For The First 35 D Postweaning On Breeding And Subsequent Lactation Performance Of Sows, G Lynch, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Four hundred and eight sows were used to evaluate the effects of feeding high levels of vitamins (2 to 7 times average inclusion rate) for the first 35 d postbreeding on later reproduction performance. number of pigs born alive and number born dead following feeding high vitamin levels showed a numeric advantage compared with sows fed the control diet. These numeric responses resulted in trends toward higher number weaned (9.75 vs 9.54) and litter weaning weight (l 07.8 vs 105.4 lb). Further research needs to be conducted to determine which vitamin or vitamins may have an ...


The Effects Of Increasing Dietary Energy Density On Growing-Finishing Pig Growth Performance And Carcass Characteristics, J W. Smith Ii, R M. Musser, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach Jan 1995

The Effects Of Increasing Dietary Energy Density On Growing-Finishing Pig Growth Performance And Carcass Characteristics, J W. Smith Ii, R M. Musser, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred gilts were used in a growth trial to evaluate the effects of increasing dietary energy density on growing-finishing pig growth performance and carcass characteristics. In this trial, adding fat to corn-soybean meal diets with a constant calorie: lysine ratio to increase the energy density during the growing phase (98 to 160 lb) improved feed efficiency with no influence on growth rate. However, increasing the energy content of the diet by adding fat had no benefit during the finishing phase (160 to 233 lb).; Swine Day, Manhattan, KS, November 16, 1995


Flavor And Aroma Of Low-Dose Irradiated, Boneless, Pork Chops, S E. Luchsinger, Zepeda C.M. Garcia, Edgar Iv Chambers, M E. Hollingsworth, Melvin C. Hunt, James L. Marsden, Sally L. Stroda, Canas E. Rubio J, Curtis L. Kastner, W G. Kuecker, T Mata, Donald H. Kropf Jan 1995

Flavor And Aroma Of Low-Dose Irradiated, Boneless, Pork Chops, S E. Luchsinger, Zepeda C.M. Garcia, Edgar Iv Chambers, M E. Hollingsworth, Melvin C. Hunt, James L. Marsden, Sally L. Stroda, Canas E. Rubio J, Curtis L. Kastner, W G. Kuecker, T Mata, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Irradiation and irradiation source had little to no effect on flavor and aroma of boneless pork chops, either frozen or chilled. Coupled with consumer concerns about food safety and well-documented improvement in consumer attitudes about irradiated foods, irradiation of boneless pork chops has promising potential for market acceptance.; Swine Day, Manhattan, KS, November 16, 1995


Test Weight Affects The Milling Characteristics Of Grain Sorghum, S L. Traylor, Timothy J. Herrman, Keith C. Behnke, Joe D. Hancock Jan 1995

Test Weight Affects The Milling Characteristics Of Grain Sorghum, S L. Traylor, Timothy J. Herrman, Keith C. Behnke, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

As test weight was reduced from normal to intermediate (i.e., from 58 to 52 lb/bu), little change occurred in milling characteristics of grain sorghum. However, as test weight was decreased from intermediate to light (52 to 39 lb/bu), production rate slowed and cost of grinding increased dramatically. Decreasing screen opening size from 8/64 in to 3/64 in also decreased production rates and increased electrical energy costs, with these effects much more pronounced in light test-weight sorghum.; Swine Day, Manhattan, KS, November 16, 1995


Effects Of Distillers Grains On Growth Performance In Nursery And Finishing Pigs, B W. Senne, P S. Sorrell, I H. Kim, S L. Traylor, Robert H. Hines, Joe D. Hancock, Keith C. Behnke Jan 1995

Effects Of Distillers Grains On Growth Performance In Nursery And Finishing Pigs, B W. Senne, P S. Sorrell, I H. Kim, S L. Traylor, Robert H. Hines, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Rate and efficiency of gain were not affected by adding as much as 20% distillers dried grains in isocaloric diets for nursery pigs or 30% in isocaloric diets for finishing pigs. These results demonstrate that the previously suggested maximums of 5% distillers dried grains in nursery diets and 10% distillers dried grains in finishing diets are too conservative. Finally, because the 20% (nursery) and 30% (finishing) treatments were the greatest concentrations used in our experiments, additional growth assays are needed to determine the maximum limits for distillers dried grains in diets for pigs.; Swine Day, Manhattan, KS, November 16, 1995


Interactions Among Lactose, Spray-Dried Animal Plasma, And Soybean Meal Levels May Affect Segregated Early-Weaned Pigs, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, R E. Musser, K Q. Owen, J W. Smith Ii, B T. Richert, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1995

Kansas Agricultural Experiment Station Research Reports

Pigs weaned in a segregated early weaning (SEW) environment achieved maximum performance when fed a sequence of diets containing a gradual decrease in spray-dried animal plasma. Furthermore, pigs weaned at approximately 19 days responded positively to 20% soybean meal. Increased levels of lactose enhanced the increases in performance from soybean meal.; Swine Day, Manhattan, KS, November 16, 1995


Estimated Budgets For Separate-Site Swine Production, Kevin C. Dhuyvetter, Michael D. Tokach, R D. Jones Jan 1995

Estimated Budgets For Separate-Site Swine Production, Kevin C. Dhuyvetter, Michael D. Tokach, R D. Jones

Kansas Agricultural Experiment Station Research Reports

Budgets were developed to help Kansas swine producers analyze the economics of separate-site production. Return on investment (ROI) was estimated at 9.5%in each of the three production phases. Returns over total costs were very sensitive to transfer price between phases (weaned pig and feeder pig price) as well as production efficiencies and input costs.; Swine Day, Manhattan, KS, November 16, 1995


Effects Of Crowding And Intermittent Feed Intake On Growth Performance And Development Of Stomach Lesions In Finishing Pigs, P Sorrell, L L. Burnham, I H. Kim, G A. Kennedy, Robert H. Hines, Joe D. Hancock Jan 1995

Effects Of Crowding And Intermittent Feed Intake On Growth Performance And Development Of Stomach Lesions In Finishing Pigs, P Sorrell, L L. Burnham, I H. Kim, G A. Kennedy, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Pigs in uncrowded pens (12 ft^2/pig) consumed more feed, gained at a greater rate, and tended to develop fewer stomach lesions than pigs in crowded pens (6 ft^2/pig). Pigs with ad libitum access to feed consumed more feed and gained at a greater rate than pigs deprived of feed for 24-h periods twice each week. The resulting intermittent feed intake increased the severity of stomach lesions but only for uncrowded pigs. In conclusion, crowding slowed growth for all pigs and increased the severity of stomach lesions. Intermittent feed intake also slowed growth, but its effects on ...


Omitting Vitamin And Trace Mineral Premixes From Diets During Late Finishing (190 To 250 Lb) Did Not Reduce Growth Performance, Carcass Leanness, Or Muscle Quality, I H. Kim, L L. Burnham, Robert H. Hines, M M. Rantanen, I Mavromichalis, Joe D. Hancock, Donald H. Kropf, Keith C. Behnke Jan 1995

Omitting Vitamin And Trace Mineral Premixes From Diets During Late Finishing (190 To 250 Lb) Did Not Reduce Growth Performance, Carcass Leanness, Or Muscle Quality, I H. Kim, L L. Burnham, Robert H. Hines, M M. Rantanen, I Mavromichalis, Joe D. Hancock, Donald H. Kropf, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Average daily gain; F/G; dressing percentage; tenth rib fat thickness; and depth, marbling, color, and firmness of the longissimus muscle were not influenced by omitting the vitamin and(or) trace mineral premixes from diets during late finishing (190 to 250 lb). Thus, our data suggest that the KSU vitamin and trace mineral premixes can be omitted during late finishing to reduce cost of gain without decreasing growth performance, carcass merit, or muscle quality.; Swine Day, Manhattan, KS, November 16, 1995


Particle Size (1,000 Vs 500 Um) Affects Nutritional Value Of Simple And Complex Diets For Weanling Pigs And Broiler Chicks, I H. Kim, M R. Cabrera, Robert H. Hines, M M. Rantanen, Joe D. Hancock, Keith C. Behnke Jan 1995

Particle Size (1,000 Vs 500 Um) Affects Nutritional Value Of Simple And Complex Diets For Weanling Pigs And Broiler Chicks, I H. Kim, M R. Cabrera, Robert H. Hines, M M. Rantanen, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Nursery pigs fed complex diets had greater ADG than those fed simple diets, and as particle size was reduced, ADG and F/G tended to improve. There was a trend for reducing particle size to increase ADG more for pigs fed simple versus complex diets, but the response in efficiency of gain was of similar magnitude regardless of diet complexity. A second experiment was designed to determine if broiler chicks were an acceptable model for predicting the effects of feed processing procedures on nursery pigs. Chicks responded somewhat differently than pigs to the diet complexity x particle size treatments, with ...


Sodium Sulfite And Extrusion Affect The Nutritional Value Of Soybean Products For Nursery Pigs, L L. Burnham, I H. Kim, Robert H. Hines, Terry L. Gugle, Joe D. Hancock Jan 1995

Sodium Sulfite And Extrusion Affect The Nutritional Value Of Soybean Products For Nursery Pigs, L L. Burnham, I H. Kim, Robert H. Hines, Terry L. Gugle, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Extruded soybeans improved rates and efficiencies of gain when fed to nursery pigs in place of soybean meal (SBM). Sodium sulfite (an extrusion aid) increased extruder throughput and improved d 13 to 35 and overall efficiency of growth in pigs fed extruded soybeans and unextruded SBM. Further research is needed to determine if greater sodium sulfite concentrations will continue to increase extruder throughput and to elucidate the mechanism for improved growth performance of pigs fed sodium sulfite with unextruded SBM.; Swine Day, Manhattan, KS, November 16, 1995


Effects Of Various Fractions Of Spray-Dried Plasma Protein On Performance Of Early-Weaned Pigs, K Q. Owen, K G. Friesen, B T. Richert, J W. Smith Ii, L E. Russell, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach Jan 1995

Effects Of Various Fractions Of Spray-Dried Plasma Protein On Performance Of Early-Weaned Pigs, K Q. Owen, K G. Friesen, B T. Richert, J W. Smith Ii, L E. Russell, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to determine the individual protein fraction (IgG, low molecular weight peptides and albumin) contained in spray-dried plasma protein responsible for stimulating feed intake. In Exp. 1, pigs (21 d of age) fed a diet containing the IgG protein fraction had similar performance to pigs fed a plasma protein diet. In Exp. 2, two fractions of spray-dried porcine plasma, IgG and albumin, were evaluated with pigs (10 d of age). Pigs fed either fraction had performance similar to pigs fed plasma protein.; Swine Day, Manhattan, KS, November 16, 1995


Wheat Gluten And Spray-Dried Plasma Protein Blends For Nursery Pigs, L L. Burnham, I H. Kim, Robert H. Hines, Joe D. Hancock Jan 1995

Wheat Gluten And Spray-Dried Plasma Protein Blends For Nursery Pigs, L L. Burnham, I H. Kim, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Using a 50:50 blend of spray-dried plasma protein (SDPP):spray-dried wheat gluten (WG) (i.e., with each as approximately 4% of the diet) gave the greatest ADG and ADFI, while reducing diet costs compared to the control diet (i.e., 8% SDPP). Even with a slight decrease in efficiency of gain, the marked decrease in diet cost will yield better cost of gain with a 50:50 blend versus using only SDPP.; Swine Day, Manhattan, KS, November 16, 1995


In Vitro Branched Chain Amino Acid Oxidation By Porcine Mammary Tissue, B T. Richert, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen Jan 1995

In Vitro Branched Chain Amino Acid Oxidation By Porcine Mammary Tissue, B T. Richert, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Mammary secretory tissue from six (three each of parity 1 and 2) lactating sows (d 10 to 17 of lactation) was obtained via biopsy for in vitro incubation to determine CO2 production fr01TI individual branched chain amino acids. Carbon dioxide production levels as percentages of the 14C-labeled amino acid metabolized by the mammary tissue were 2.57, 1.86, and 4.07% for isoleucine, leucine, and valine, respectively (P< .03). These results indicate that, in the lactating sow mammary gland, valine has the greatest oxidation rate of the branched chain amino acids.; Swine Day, Manhattan, KS, November 16, 1995

Summary Of Kansas State University Swine Enterprise Record 1995, B T. Richert, Michael R. Langemeier, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

The Kansas Swine Enterprise Record Program evaluates biological and economic performance and is part of a cooperative record-keeping project with extension personnel and swine producers in Kansas, Nebraska, and South Dakota. From July 1, 1994 to June 31, 1995, profit per cwt of pork produced for these producers (37 semi-annual and 20 annual data) averaged $4.75 for the first 6 months of 1995, but a loss of $1.22 occurred for the past year. Producers in the top one-third in terms of profitability had average profits of $3.44 per cwt, whereas producers in the bottom one-third had average ...


The Interactive Effects Of Turbozyme 160 And Diet Complexity On Starter Pig Growth Performance, M L. Lofing, J R. Bergstrom, W B. Nessmith Jr, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen Jan 1995

The Interactive Effects Of Turbozyme 160 And Diet Complexity On Starter Pig Growth Performance, M L. Lofing, J R. Bergstrom, W B. Nessmith Jr, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

These results suggest that feeding a complex starter diet improves initial (d 0 to 7 postweaning) growth performance of segregated early-weaned pigs. Feeding either a simple or complex diet with added Turbozyme 160 improves feed efficiency from day 0 to 14 postweaning. However, for the overall experimental period, neither a complex diet nor added Turbozyme 160 had any effect on growth performance.; Swine Day, Manhattan, KS, November 16, 1995

Kansas Agricultural Experiment Station Research Reports

A study was conducted to evaluate the effects of replacing spray-dried plasma protein with spray-dried whole egg from egg grading plants on starter pig performance. Up to 50% (3.5% of the diet) of spray-dried plasma protein can be replaced with spraydried whole egg (6% of the diet) without influencing performance of starter pigs.; Swine Day, Manhattan, KS, November 16, 1995


Determining The Optimal Threonine: Lysine Ratio In Starter Diets For The Segregated Early-Weaned Pig, J R. Bergstrom, K Q. Owen, B T. Richert, W B. Nessmith Jr, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz Jan 1995

Determining The Optimal Threonine: Lysine Ratio In Starter Diets For The Segregated Early-Weaned Pig, J R. Bergstrom, K Q. Owen, B T. Richert, W B. Nessmith Jr, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A 35-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% digestible lysine) and six digestible threonine:lysine ratios (50, 55, 60, 65, 70, and 75%) in a 2 x 6 factorial arrangement. Growth performance was improved by feeding 1.5% digestible lysine, rather than 1. 15% digestible lysine. However, growth performance was not improved by increasing dietary threonine. These data indicate that the threonine requirement is no more than 50% of digestible lysine.; Swine ...


A Comparison Of Risk And Return For Contract And Independent Hog Finishing, J L. Parcell, Michael R. Langemeier Jan 1995

A Comparison Of Risk And Return For Contract And Independent Hog Finishing, J L. Parcell, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Risks associated with independent hog finishing have prompted producers to seek alternative production and marketing methods. A means of reducing risk has developed through contract hog finishing. Research results indicate that risk-neutral producers require contract base payments ranging from $11.25 to $14.00 per head. Strongly risk-averse producers require contract base payments ranging from $4.75 to $7.75 per head. The lower ends of the ranges are for a contract with performance incentives. The upper ends of the ranges are for a flat contract without performance incentives. Calculated required base payments are similar to those payments currently received ...

Kansas Agricultural Experiment Station Research Reports

Irradiation and vacuum-packaging caused a more intense and stable red color in boneless pork chops. Irradiation up to 2.5 kGy increased cooked internal redness in chilled chops. Oxidative rancidity was greater in aerobic packaging than vacuum-packaging and in irradiated aerobic packaged chops than controls. Irradiation of vacuum-packaged boneless pork chops has promising potential for market acceptance.; Swine Day, Manhattan, KS, November 16, 1995


Effects Of Feeder Design And Pelleting On Growth Performance And Water Use In Finishing Pigs, M M. Rantanen, Robert H. Hines, I H. Kim, Joe D. Hancock Jan 1995

Effects Of Feeder Design And Pelleting On Growth Performance And Water Use In Finishing Pigs, M M. Rantanen, Robert H. Hines, I H. Kim, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Pigs fed from wet-dry feeders had 4% greater ADG with 50% less water usage than those consuming feed from dry feeders. Pelleting diets improved F/G by 4% compared to meal diets. However, the benefits of pelleting were primarily when a dry feeder was used, with little evidence to support use of both pelleting and wet/dry feeders for finishing pigs.; Swine Day, Manhattan, KS, November 16, 1995


The Effects Of Increasing Dietary Energy Density On Growing-Finishing Pig Growth Performance And Carcass Characteristics, J W. Smith Ii, R M. Musser, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach Jan 1995

The Effects Of Increasing Dietary Energy Density On Growing-Finishing Pig Growth Performance And Carcass Characteristics, J W. Smith Ii, R M. Musser, W B. Nessmith Jr, J R. Bergstrom, J A. Loughmiller, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred gilts were used in a growth trial to evaluate the effects of increasing dietary energy density on growing-finishing pig growth performance and carcass characteristics. In this trial, adding fat to corn-soybean meal diets with a constant calorie: lysine ratio to increase the energy density during the growing phase (98 to 160 lb) improved feed efficiency with no influence on growth rate. However, increasing the energy content of the diet by adding fat had no benefit during the finishing phase (160 to 233 lb).; Swine Day, Manhattan, KS, November 16, 1995


Low-Phosphorus Diets During Late-Finishing Decrease Cost Of Gain With Minimal Effect On Growth Performance, Carcass Characteristics, And Meat Quality, I Mavromichalis, I H. Kim, L L. Burnham, M M. Rantanen, Robert H. Hines, Joe D. Hancock, Donald H. Kropf, Keith C. Behnke Jan 1995

Low-Phosphorus Diets During Late-Finishing Decrease Cost Of Gain With Minimal Effect On Growth Performance, Carcass Characteristics, And Meat Quality, I Mavromichalis, I H. Kim, L L. Burnham, M M. Rantanen, Robert H. Hines, Joe D. Hancock, Donald H. Kropf, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Partially omitting (up to 66 %) the supplemental inorganic phosphorus (P) source from a late-finishing (190 to 250 lb) diet resulted in slightly greater ADG and backfat thickness, which probably resulted from the greater feed (energy) intake. Meat quality was unaffected by treatment. Thus, during late-finishing, a total P concentration of .40% can be used to decrease diet cost without decreasing performance or meat quality of high-lean pigs.; Swine Day, Manhattan, KS, November 16, 1995
