Influence Of Lysine Level Fed From 40 To 80 Lb On Growth Performance And Carcass Composition Of Barrows And Gilts (1999), Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
A total of 1,200 pigs was used to determine the influence of lysine level fed from 40 to 80 Ib on growth performance and carcass composition. Barrows and gilts were fed com-soybean meal-based diets with 6% added fat formulated to .80, .95, 1.10, 1.25, or 1.40% total lysine. Increasing dietary lysine improved ADG and F/G in a linear and quadratic manner with optimal ADG at 1.10% lysine and optimal F/G at 1.400/0 lysine. Economic returns over feed costs were similar at 1.10, 1.25, and 1.40% lysine.; Swine Day, Manhattan, KS, November 18, 1999

A trial was conducted to evaluate the effects of modified tall oil (MTO) on growth and body composition of adult ovariectomized rats. This trial was targeted as a model for postmenopausal women; thus, only data applicable to swine production are presented herein. Feeding MTO decreased adiposity, increased concentrations of certain lipids in tissues, increased vitamin E (octocopherol) levels in the adipose, and increased actual lean content. These data lend support to the carcass leanness and meat quality improvements routinely seen in swine from feeding MTO.; 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 (1999), 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
Effects Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts (1999), 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
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 effects …

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 diets …

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 …
Lack Of Interaction Between Lysine Levels Fed In Growing And Finishing Diets (1999), Rops Steve, Heintz Marty, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Lack Of Interaction Between Lysine Levels Fed In Growing And Finishing Diets (1999), Rops Steve, Heintz Marty, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz
Kansas Agricultural Experiment Station Research Reports
A total of 1,200 pigs were used to determine whether dietary lysine level fed in the growing phase influenced the response to lysine level fed in the finishing phase. Pigs were fed either an adequate or low lysine level during the growing (60 to 170 lb) and/ or finishing phase (170 to 265 lb). Feeding a deficient lysine level decreased ADG and F/G during the phase when the deficient diet was fed; however, lysine level fed in the growing phase did not influence the response in the finishing phase. Carcass parameters were influenced more by the lysine level fed in …

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
