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

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 Jan 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 ...


Additional L-Carnitine In The Gestating Sow Diet Improves Carcass Characteristics Of The Offspring, R E. Musser, Duane L. Davis, K Q. Owen, R E. Campbell, S Hanni, J S. Bauman, M Heintz, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz Jan 1999

Kansas Agricultural Experiment Station Research Reports

A total of 232 sows was used to determine the effects of an additional 50 ppm of L-carnitine in the gestation diet on sow and offspring performance. No differences were observed in either the immediate or subsequent number of pigs born or born alive per litter (P>.l 0). No differences were observed in pig weight at birth, weaning, or d 60 of age. Muscle fiber analysis of newborn pigs indicated a tendency for a larger cross-sectional area of the semitendinosus muscle; increased primary (slow-twitch, red) fibers; and a higher ratio of primary to secondary fibers (fast-twitch, white). No differences ...


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 Jan 1999

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 ...


Lack Of Interaction Between Lysine Levels Fed In Growing And Finishing Diets, Rops Steve, Heintz Marty, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1999

Lack Of Interaction Between Lysine Levels Fed In Growing And Finishing Diets, 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 ...


Effects Of Increased Feed Intake In Early Gestation On Sow Farrowing Performance And Offspring Carcass Characteristics, R E. Musser, Duane L. Davis, M Heintz, J Bauman, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1999

Kansas Agricultural Experiment Station Research Reports

Three hundred and ninety-four PIC sows were used to determine the effects of increased feed intake during two critical stages of fetal development on farrowing performance and offspring carcass characteristics. Sows were fed 8 Ibid for one of three periods, d 10 to 30, d 30 to 50, or d 10 to 50 of gestation in comparison to a control level of 4 Ibid. Treatments did not affect the number of pigs farrowed. Sows fed 8 Ibid of complete diet from d 10 to 30 of gestation tended to have offspring with heavier hot carcass weight (P = .16) compared to ...

Kansas Agricultural Experiment Station Research Reports

Forty-seven growing pigs (initially 65 ± 2 lb) were used in a metabolism study to determine the effects of a single respiratory disease challenge on growth performance, infrared thermal radiation, and serum acute phase proteins. Thirty pigs were challenged with Actinobacillus pleuropneumonia, and seven pigs were assigned to an ad libitum-fed nonchallenged control group. Ten additional nonchallenged pigs were pair-fed the feed intake of an A. pleuropneumonia-challenged counterpart. There were five 4 d collection periods (d 4 to 7, d 8 to 11, d 12 to 15, d 16 to 19, and d 22 to 25), and the A. pleuropneumonia ...
