Kansas Agricultural Experiment Station Research Reports
This file includes the 2023 Swine Day Research Report introduction, standard abbreviations, K-State Vitamin and Trace Mineral Premixes statement, biological variability and chances of error explanation, and acknowledgments of our supporters. We hope that the information in the 2023 Swine Day Research Report will be of benefit as we attempt to meet the needs of the Kansas swine industry.
Effect Of The Feed Additive Fytera Start On Growth Performance And Stool Quality Of Nursery Pigs Fed Nutritional And Pharmacological Copper And Zinc Diets, Ty H. Kim, Jason C. Woodworth, Mike D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jordan T. Gebhardt, Chris P. A. Van De Ligt
Effect Of The Feed Additive Fytera Start On Growth Performance And Stool Quality Of Nursery Pigs Fed Nutritional And Pharmacological Copper And Zinc Diets, Ty H. Kim, Jason C. Woodworth, Mike D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jordan T. Gebhardt, Chris P. A. Van De Ligt
Kansas Agricultural Experiment Station Research Reports
A total of 340 barrows (DNA 200 × 400; initially 13.4 ± 0.17 lb BW) were used in a 38-d growth study to determine the effect of Fytera Start (Selko, Indianapolis, IN) in diets with or without pharmacological levels of Zn and Cu on growth performance and stool quality of nursery pigs. Fytera Start is a blend of botanical extracts that has recently been introduced for use in nursery pig diets. Pigs were weaned at approximately 21 d of age, randomly allotted to pens based on initial BW, and then allotted to 1 of 4 dietary treatments in a completely …
Evaluating The Effects Of Hiphorius Phytase Added In Diets At Or Below The P Requirement On Nursery Pig Growth Performance And Bone Mineralization, Macie E. Reeb, Jason C. Woodworth, Joel M. Derouchey, Mike D. Tokach, Robert D. Goodband, Jordan T. Gebhardt, Jon R. Bergstrom
Evaluating The Effects Of Hiphorius Phytase Added In Diets At Or Below The P Requirement On Nursery Pig Growth Performance And Bone Mineralization, Macie E. Reeb, Jason C. Woodworth, Joel M. Derouchey, Mike D. Tokach, Robert D. Goodband, Jordan T. Gebhardt, Jon R. Bergstrom
Kansas Agricultural Experiment Station Research Reports
A total of 297 pigs (DNA 241 × 600; initially 8.64 ± 0.181 kg) were used in a 21-d trial to determine the effects of HiPhorius phytase on growth performance and bone characteristics. Pens of pigs were assigned to 1 of 5 treatments in a randomized complete block design with 5 pigs per pen and 12 replications per treatment. The first three diets were formulated to contain 0.09% aP; without added phytase (control), or the control diet with 600 or 1,000 FYT/kg of added phytase (considering a release of 0.15 or 0.18% aP, respectively). The remaining two diets were formulated …
Effects Of Altering Dietary Acid-Binding Capacity-4 With Specialty Soy Protein Sources Or Acidifiers On Nursery Pig Performance And Fecal Dry Matter, Ethan B. Stas, Mike D. Tokach, Jason C. Woodworth, Joel M. Derouchey, Robert D. Goodband, Jordan T. Gebhardt
Effects Of Altering Dietary Acid-Binding Capacity-4 With Specialty Soy Protein Sources Or Acidifiers On Nursery Pig Performance And Fecal Dry Matter, Ethan B. Stas, Mike D. Tokach, Jason C. Woodworth, Joel M. Derouchey, Robert D. Goodband, Jordan T. Gebhardt
Kansas Agricultural Experiment Station Research Reports
A total of 300 pigs (241 × 600 DNA; initially 13.2 lb) were used to evaluate the effects of altering the dietary acid-binding capacity-4 (ABC-4) with specialty soy protein sources or acidifiers on nursery pig performance and fecal dry matter (DM). At weaning, pigs were allotted to 1 of 5 dietary treatments. There were 5 pigs per pen and 12 replications per treatment. Pigs were fed experimental diets in two phases with phase 1 fed from d 0 to 10 post-weaning followed by phase 2 from d 10 to 24. Diets were formulated with increasing ABC-4. A single low ABC-4 …
Determining The Phosphorus Release Curve For Sunphase Ht Phytase From 250 To 2,000 Ftu/Kg In Nursery Pig Diets, Ty H. Kim, Katelyn N. Gaffield, Mike D. Tokach, Joel M. Derouchey, Jason C. Woodworth, Robert D. Goodband, Jordan T. Gebhardt, Ying Zhou, Xuerong Song, Xiuyi Wu, Mikhail Y. Golovko, Svetlana A. Golovko

Kansas Agricultural Experiment Station Research Reports
A total of 280 pigs (DNA 241 × 600; initially 22.9 ± 0.52 lb BW) were used in a 21-d growth study to determine the available P (aP) release curve for Sunphase HT phytase (Wuhan Sunhy Biology Co., Ltd.; Wuhan, P.R. China). At approximately 19 d of age, pigs were weaned, randomly allotted to pens, and fed common starter diets. Pigs were blocked by average pen body weight (BW) and randomly allotted to 1 of 7 dietary treatments on d 21 post-weaning, considered d 0 of the study. Dietary treatments were derived from a single basal diet, and ingredients including …
