High preweaning mortality (PWM) rates for piglets are a significant concern for the worldwide pork industries, causing economic loss and well-being issues. This study focused on identifying the factors affecting PWM, overlays, and predicting PWM using historical production data with statistical and machine learning models. Data were collected from 1,982 litters from the United States Meat Animal Research Center, Nebraska, over the years 2016 to 2021. Sows were housed in a farrowing building with three rooms, each with 20 farrowing crates, and taken care of by well-trained animal caretakers. A generalized linear model was used to analyze the various sow, …

Swine are a major reservoir of an array of zoonotic Salmonella enterica subsp. enterica lineage I serovars including Derby, Typhimurium, and 4,[5],12:i:- (a.k.a. Monophasic Typhimurium). In this study, we assessed the gastrointestinal (GI) microbiome composition of pigs in different intestinal compartments and the feces following infection with specific zoonotic serovars of S. enterica (S. Derby, S. Monophasic, and S. Typhimurium). 16S rRNA based microbiome analysis was performed to assess for GI microbiome changes in terms of diversity (alpha and beta), community structure and volatility, and specific taxa alterations across GI biogeography (small and large intestine, feces) …
Evaluation Of Boron Supplementation In Swine And Poultry, Tyler B. Chevalier
Evaluation Of Boron Supplementation In Swine And Poultry, Tyler B. Chevalier
Theses and Dissertations--Animal and Food Sciences
The objectives of this dissertation were to evaluate dietary boron (B) supplementation as sodium borate in various swine models and broiler chicks through a series of experiments. The initial experiment evaluated supplemental B (0, 25, 50, and 100 ppm B) on serum insulin, glucose, and clinical chemistry panel of growing pigs. Serum insulin/glucose ratio tended to decrease linearly with increasing supplemental B in a fasting state (P = 0.08). These findings were more noticeable (linear effect, P = 0.02) in a postprandial state (~ 50 minutes following a meal). A series of follow-up studies further evaluating B supplementation (0, 5, …
Foreword, Swine Day 2023
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.

Kansas Agricultural Experiment Station Research Reports
A total of 360 weanling barrows (DNA 200 × 400; initially 13.0 ± 0.07 lb) were used in a 38-d study to evaluate the effects of diets containing different levels of a novel Zn source (HiZox, Animine Precision Minerals, Annecy, France) and different levels of crude protein (CP) in low acid-binding capacity at pH 4 (ABC-4) diets on growth performance and fecal characteristics. Pigs were randomly assigned to pens (5 pigs per pen) and pens were assigned to 1 of 6 treatments with 12 pens per treatment. Diets were fed in 3 phases: phase 1 from d 0 to 10, …
Effects Of Increasing Energy Or Lysine In Soybean Meal-Based Diets On Early And Late Finishing Pig Performance, Ty H. Kim, Jamil E. G. Faccin, Robert D. Goodband, Mike D. Tokach, Joel M. Derouchey, Jason C. Woodworth, Jordan T. Gebhardt

Kansas Agricultural Experiment Station Research Reports
A total of 2,265 finishing pigs (337 × 1050 PIC; initially 110.7 ± 6.14 lb) were used in two 28-d trials to determine the effect of increasing energy or lysine in soybean meal-based diets on early and late finishing pig performance. Pigs were housed in mixed gender pens with 27 pigs per pen and 21 pens per treatment. Soybean meal (SBM) NE values used in diet formulation were either 946 kcal/lb (78% NE of corn; NRC) or 1,212 kcal/lb (100% NE of corn). The treatments were structured as a completely randomized design. Treatments consisted of: 1) a diet containing a …
Effects Of Increasing Levels Of Soybean Meal In Nursery Diets On Growth Performance And Fecal Characteristics Of 22- To 60-Lb Pigs, Jamil E. G. Faccin, Robert D. Goodband, Mike D. Tokach, Joel M. Derouchey, Jordan T. Gebhardt, Jason C. Woodworth
Effects Of Increasing Levels Of Soybean Meal In Nursery Diets On Growth Performance And Fecal Characteristics Of 22- To 60-Lb Pigs, Jamil E. G. Faccin, Robert D. Goodband, Mike D. Tokach, Joel M. Derouchey, Jordan T. Gebhardt, Jason C. Woodworth
Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted to determine the effects of increasing soybean meal (SBM) on late nursery pig performance. In Exp. 1, a total of 266 pigs (241 × 600 DNA; initially 22.2 ± 0.37 lb) were used in a 21-d trial with 14 replicate pens per treatment and 4 to 5 pigs per pen. Pens of pigs were randomly assigned to 1 of 4 dietary treatments which were corn-based with SBM levels of 25.0, 28.9, 32.5, or 36.2%. In Exp. 2, a total of 340 pigs (241 × 600 DNA; initially 29.8 ± 0.40 lb) were used in a 21-d …
