Kansas Agricultural Experiment Station Research Reports
The objective of this study was to establish a range of soybean meal quality to evaluate the correlations between official analytical methods and near-infrared reflectance spectroscopy (NIRS). Crushed soybean white flakes (Mark Hershey Farms, Lebanon, PA) exposed to mechanical oil extraction, but not heat processing, were used in this experiment. Ground samples (500 g) were put into cotton bags and autoclaved at 262°F for 0, 5, 10, 15, 30, 45, and 60 min at 29 PSI. This was done to simulate varying degrees of heat processing. A total of 2 samples per treatment were autoclaved in 3 separate blocks. The …

Kansas Agricultural Experiment Station Research Reports
A total of 467 sows were used in a study to evaluate the effect of feeding duration of increased lysine (Lys) and energy prior to farrowing on sow and litter performance, piglet survival, and colostrum quality. Sows were blocked by body weight and parity category on d 106 of gestation, and allotted to one of three dietary treatments: 1) 4.5 lb/d gestation feed (12.5 g SID Lys and 6.5 Mcal ME) until d 113 of gestation, then 6 lb/d lactation feed (28 g SID Lys and 9.4 Mcal ME) until parturition; 2) 4.5 lb/d gestation feed (12.5 g SID Lys …
Effect Of Phase-Feeding Strategies On Growth Performance And Carcass Characteristics Of Growing-Finishing Pigs: Strategies To Reduce Dietary Phases Using A Field Approach On Lysine Levels, M. B. Menegat, S. S. Dritz, M. D. Tokach, J. C. Woodworth, J. M. Derouchey, R. D. Goodband
Effect Of Phase-Feeding Strategies On Growth Performance And Carcass Characteristics Of Growing-Finishing Pigs: Strategies To Reduce Dietary Phases Using A Field Approach On Lysine Levels, M. B. Menegat, S. S. Dritz, M. D. Tokach, J. C. Woodworth, J. M. Derouchey, R. D. Goodband
Kansas Agricultural Experiment Station Research Reports
The objective of this study was to evaluate whether simplification of phase-feeding strategies using a field approach with lysine specifications slightly below the estimated requirement for maximum growth rate is possible without compromising overall performance and carcass characteristics of grow-finish pigs. A total of 1,188 pigs (PIC; 359 × 1050; initially 63.5 lb body weight (BW)) were used in a randomized complete block design with 27 pigs per pen and 11 pens per treatment under commercial research conditions. Treatments consisted of four feeding programs with lysine specifications set at 98.5% of estimated requirements for maximum growth rate and 97.5% of …
