Economics Of Adding Fat And Increasing Lysine:Calorie Ratio In Diets For Growing-Finishing Gilts, M De La Llata, Michael R. Langemeier, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 1,200 gilts was used to evaluate the economics ofadding fat and increasing lysine:calorie ratio in diets for growing-finishing pigs. Diets were fed in four phases and consisted of a 2 x 4 factorial arrangement with two levels of fat (0 and 6%) and four increasing lysine:calorie ratios. Eight economic scenarios combining com, soybean meal, fat, and hog prices with two packer grading systems were created. Stochastic dominance analysis was performed on 64 alternatives (8 treatments x 8 scenarios). The third "and fourth (higher) lysine: calorie ratios increased income over feed cost when fat was ...


Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Pork Chop Display Color Stability, Warnerbratzler Shear, And Sensory Panel Traits, A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach Jan 1999

Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Pork Chop Display Color Stability, Warnerbratzler Shear, And Sensory Panel Traits, A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred (PIC) gilts were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet), chromium nicotinate (0 or 50 ppb), and L-carnitine (0 or 50 ppm) on display color stability, Warner-Bratzler shear, and sensory panel traits of pork chops. Dietary additions of MTO, chromium nicotinate, and L-camitine to growing and finishing swine diets had minimal effects on quality characteristics and display color stability of pork chops. Therefore, producers probably can take advantage of any production or carcass cutability improvement from these feed supplements without affecting muscle quality of pork chops.; Swine Day, Manhattan ...


Market Hog Price Discovery, Ted C. Schroeder, J Mintert Jan 1999

Market Hog Price Discovery, Ted C. Schroeder, J Mintert

Kansas Agricultural Experiment Station Research Reports

Cash hog markets are declining in importance, and use of formula pricing of market hogs is increasing. Producers need more information to assist them in price discovery and formula price negotiations with pork packers. Lean hog futures and pork wholesale plus by-product values offer useful pricing information for producers. However, using these markets as sources ofprice information is not without challenges. This report highlights issues involved in hog market price discovery and examines the usefulness of lean hog futures and wholesale pork values in price discovery.; Swine Day, Manhattan, KS, November 18, 1999


Effects Of Modified Tall Oil And Creatine Monohydrate On Growth Performance, Carcass Characteristics, And Meat Quality Of Growing-Finishing Barrows, P R. O'Quinn, B S. Andrews, J C. Woodworth, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach Jan 1999

Effects Of Modified Tall Oil And Creatine Monohydrate On Growth Performance, Carcass Characteristics, And Meat Quality Of Growing-Finishing Barrows, P R. O'Quinn, B S. Andrews, J C. Woodworth, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to evaluate the effects of modified tall oil (MTO; .50% of the diet) and creatine monohydrate (CMH; 25 g/pig/day for 10 days prior to slaughter) on performance, carcass characteristics, and meat quality of finishing barrows. Feeding MTO improved ADG and F/G during the growing phase and improved F/G over the entire trial and during the 10 day CMH loading period. Feeding MTO reduced backfat, but neither CMH nor MTO affected other carcass characteristics or meat quality measures at 24 h postmortem. These data suggest that MTO improves performance and reduces backfat with ...


Interactive Effects Of Modified Tall Oil And Fat Source On Growth Performance And Carcass Characteristics Of Finishing Barrows And Gilts, J C. Woodworth, P R. O'Quinn, A T. Waylan, J T. Sawyer, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach Jan 1999

Interactive Effects Of Modified Tall Oil And Fat Source On Growth Performance And Carcass Characteristics Of Finishing Barrows And Gilts, J C. Woodworth, P R. O'Quinn, A T. Waylan, J T. Sawyer, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

A total of 144 pigs (initially 90 lb) was used to determine the interactive effects of fat source: none (NF), 6% choice white grease (CWG), or 6% poultry fat (PF); modified tall oil (MTO, 0 or .5%); and sex (barrows or gilts) on growth performance and carcass characteristics. Regardless of fat source, MTO improved belly firmness but did not influence growth performance. Gilts were leaner, had increased loin muscle area, and had softer bellies compared to barrows. Added fat decreased ADFI and improved F/G. Pigs fed PF had the best F/G, but the fattest carcasses and softest loins ...


Effects Of Pelleting And Pellet Conditioning Temperatures On Weanling Pig Performance, M U. Steidinger, Michael D. Tokach, P R. O'Quinn, J C. Woodworth, Leland J. Mckinney, B S. Borg, J M. Campbell, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1999

Effects Of Pelleting And Pellet Conditioning Temperatures On Weanling Pig Performance, M U. Steidinger, Michael D. Tokach, P R. O'Quinn, J C. Woodworth, Leland J. Mckinney, B S. Borg, J M. Campbell, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two studies were conducted to evaluate" the effects of pelleting and pellet conditioning temperature of diets containing 5% spray-dried animal plasma (SDAP) on weanling pig growth performance. In Exp. 1, conditioning temperatures evaluated were 140, 150, 160, and 170°F. In Exp. 2, pellet conditioning temperatures were 140, 155, 170, 185, and 200°F. The results suggest that pellet conditioning temperatures above 170°F decrease weanling pig performance from d 0 to 7 after weaning. Pellet conditioning temperature should not exceed 170OF (exit temperature of 180°F) for nursery diets containing 5% SDAP.; Swine Day, Manhattan, KS, November 18, 1999

Effects Of Different Zinc Oxide Sources On Weanling Pig Growth Performance, J C. Woodworth, J T. Sawyer, C A. Maxwell, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 192 pigs (initially 13.61b and 18 d of age) were used in a 27-d growth assay to determine the effects of different ZnO sources on weanling pig growth performance. The four experimental treatments consisted of a control diet or three diets containing Zn from ZnO from one of three different sources. For the entire trial, no differences occurred in growth performance of pigs fed the different ZnO sources; however, all sources increased ADG and ADFI compared to pigs fed the control diet. Economics and ingredient availability should dictate which ZnO source to use in weanling pig ...


Predicting Lysine Requirements Using Protein And Lipid Accretion Curves For Growing-Finishing Barrows, M De La Llata, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1999

Predicting Lysine Requirements Using Protein And Lipid Accretion Curves For Growing-Finishing Barrows, M De La Llata, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of240 growing-finishing barrows (75 to 260 lb) were used to model accretion rates and the lysine:calorie ratio requirement based on lipid and protein content data obtained with a real-time ultrasound. Barrows were fed eight different diets consisting of four increasing lysine:calorie ratios and two levels of fat (0 and 6%). The modeled accretion rates effectively predicted the differences between treatments in agreement with the actual data. The modeled lysine:calorie ratio requirement accurately predicted the lysine:calorie ratios that maximized growth, evaluated by either the predicted or the actual data. Lipid and protein deposition rates were ...

Kansas Agricultural Experiment Station Research Reports

Three hundred twenty, 24 lb nursery pigs were fed for 19 days to compare the effects of increasing dietary lysine from L-Iysine HCl (L-Lys) or Peptide Plusâ„¢ (PP) on growth performance. Three dietary treatments (1.025, 1.15, and 1.275% lysine) were each formulated with L-Lys and PP. Negative and positive control corn-soybean meal-based diets were formulated to .90 and 1.275% lysine, respectively. Increasing dietary lysine to 1.275% from L-Lys or PP resulted in increased performance; however, pigs fed the positive control diet had the best overall performance.; Swine Day, Manhattan, KS, November 18, 1999

Margins Of Safety Can Be Lowered For Supplemental Copper, Zinc, Iron, And Manganese In Finishing Diets Without Affecting Growth Performance, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Finishing pig diets are commonly supplemented with copper, zinc, iron, and manganese with large margins of safety compared to those suggested by NRC requirements. In this study, pigs were fed a control diet that provided these minerals supplemented at concentrations similar to current KSU recommendations, diets containing 50 and 25% of the recommendation, or a combination of 50% of the recommendations until 145 lb and no added trace minerals from 145 lb until market. The trial used pigs from 100 lb until market weight at 265 lb. No differences in growth perfonnance or carcass characteristics were observed as a result ...


Examination Of Stocking Density And Marketing Strategies In A Commercial Production Environment, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1999

Examination Of Stocking Density And Marketing Strategies In A Commercial Production Environment, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

The influence of stocking density (7.4 or 6.6 sq ft per pig) and marketing strategy (0, 1, or 2 sorts before closeout) was examined in a commercial production environment. No interaction between stocking density and marketing strategy was observed. Higher stocking density had no negative effects on growth performance or carcass characteristics. The major advantage of one or two sorts was a reduction in sort loss of $.27/cwt carcass ($.52/pig) compared to no sorts. No differences were found between one and two sorts under the packer matrix used in this study.; Swine Day, Manhattan, KS, November ...


Manure Composition From Kansas Swine Lagoons, G L. Keeler, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz Jan 1999

Manure Composition From Kansas Swine Lagoons, G L. Keeler, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Analysis of 41 manure samples from Kansas swine lagoons revealed that nutrient concentrations were higher than previously reported values from the Nebraska Cooperative Extension Service and the Midwest Planning Service. In addition, high standard deviations indicated that considerable variation exists in composition of waste in swine lagoons. Although means from some lagoons were lower, most producers had manure that analyzed higher than previously published values from other sources. These data reveal the imnportance of individual analysis of lagoons for proper application to cropland to maximize yield and environmental stewardship. Additional research needs to be completed to provide a more detailed ...


Effects Of Spray-Dried Animal Plasma Source On Weanling Pig Performance, M U. Steidinger, P R. O'Quinn, J C. Woodworth, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz Jan 1999

Effects Of Spray-Dried Animal Plasma Source On Weanling Pig Performance, M U. Steidinger, P R. O'Quinn, J C. Woodworth, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Three studies were conducted to evaluate the effects of different spray-dried animal plasma (SDAP) sources on weanling pig performance. For this study, different sources of SDAP were obtained from each of the four largest marketers. In each experiment, a different lot of each of the four plasma sources was used. Pigs were fed either a control diet or one of four diets containing different plasma sources added at 5.0 % of the total diet. The results of these experiments suggest that larger differences occur between lots or batches of SDAP then between sources of SDAP, when weanling pig performance is ...


Influence Of Dietary Supplementation Of Modified Tall Oil And Vitamin E On Bacon Characteristics, A T. Waylan, P R. O'Quinn, J C. Woodworth, S I. Koo, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach Jan 1999

Influence Of Dietary Supplementation Of Modified Tall Oil And Vitamin E On Bacon Characteristics, A T. Waylan, P R. O'Quinn, J C. Woodworth, S I. Koo, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Seventy-two crossbred (PIC) barrows were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet) and vitamin E (0, 10, or 50 IU/lb of feed) on bacon quality characteristics. Feeding MTO to pigs during both. the growing and finishing phases increased bacon slice firmness. Feeding swine MTO and vitamin E had minimal effects on bacon production, proximate analysis, and quality traits. Therefore, any of these combinations of MTO with vitamin E can be fed to swine to improve carcass traits without affecting bacon.; Swine Day, Manhattan, KS, November 18, 1999

Predicting Lysine Requirements Using Protein And Lipid Accretion Curves For Growing-Finishing Gilts, M De La Llata, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of240 growing-finishing gilts (60 to 260 lb) was used to model accretion rates and the lysine:calorie ratio requirement based on lipid and protein growth. Real-time ultrasound measurements were used to estimate lipid and protein contents. These estimates then were translated into feed intake and lysine requirements. Gilts were fed one of eight different diet regimens, consisting of four increasing lysine:calorie ratios and two levels of fat (0 and 6%). Lipid and protein deposition rates could effectively model feed intake when pigs were fed lysine:calorie ratios close to their requirement. The modeled accretion rates effectively predicted ...


Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Bacon Characteristics, A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach Jan 1999

Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Bacon Characteristics, A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred (PIC) gilts were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet), chromium nicotinate (0 or 50 ppb), and L-carnitine (0 or 50 ppm) on bacon quality characteristics. Supplementation of MTO improved bacon slice firmness. Dietary additions of MTO, chromium nicotinate, and L-carnitine to diets for growing and finishing swine had minimal effects on other bacon characteristics. Therefore, producers probably can take advantage of any improvements in production or carcass cutability from these feed supplements without affecting bacon quality.; Swine Day, Manhattan, KS, November 18, 1999


Effects Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts, P R. O'Quinn, A T. Waylan, J C. Woodworth, K Q. Owen, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach Jan 1999

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to investigate the interactive effects of modified tall oil (MTO), chromium nicotinate (CrNic), and L-carnitine on growth performance and carcass characteristics of finishing gilts. For the overall trial, MTO increased ADG and ADFI, and CrNic improved F/G. A CrNic x MTO interaction occurred for belly firmness; feeding CrNic in diets without MTO improved firmness, but feeding it in diets with MTO decreased firmness. Feeding L-carnitine did not have any beneficial effects on either growth performance or carcass characteristics. The results of this trial indicate that either CrNic or MTO will improve growth performance with minimal ...

A New Treatment For Neonatal Scours, R L. Sedlacek, E K. O'Donnell, A K. Singh, R J. Bridges, Metre D.C. Van, Bruce D. Schultz

Kansas Agricultural Experiment Station Research Reports

Scours account for significant losses to the US swine industry every year. A common treatment for scours is the administration of broad-spectrum antibiotics, a practice with increasing unpopularity in the eyes of consumers. Currently, no treatment is available to reduce or eliminate the fluid losses associated with scours that is both inexpensive and easy to use. In the present study, a variety of prospective drugs were used to determine if a single compound might inhibit the effects of bacterial toxins in a laboratory setting. The results indicate that a new class of drugs, which we call DASUs, likely will prove ...

Kansas Agricultural Experiment Station Research Reports

Seventy-two crossbred (PIC) barrows were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet) and vitamin E (0, 10, or 50 IU/lb of feed) on display color stability, Warner-Bratzler shear, and sensory panel traits of pork chops. Feeding MTO in combination with high levels of vitamin E to pigs during both the growing and finishing phases improved display color stability and delayed lipid oxidation of the pork loin chops without affecting tenderness and sensory evaluations. Therefore, feeding swine MTO (.5%) with high levels of vitamin E (50 IU/lb of feed) can ...

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to investigate the interactive effects of modified tall oil (MTO) and vitamin E on growth performance and carcass characteristics of growing-finishing barrows. Feeding MTO resulted in increased ADG and improved F/G during the growing phase; otherwise dietary treatment did not affect growth performance during the rest of the trial or overall. Feeding MTO also decreased backfat thickness and increased belly firmness. Increasing vitamin E in diets containing MTO decreased drip loss percentage of the loin. These results indicate that MTO may function as a growth promoter; reduce backfat; and in conjunction with vitamin E, itnprove ...
