Kansas Agricultural Experiment Station Research Reports
A total of 330 pigs (241 × 600, DNA; initially 10.7 lb) were used to determine the influence of dietary protein source on growth performance in nursery pigs. At weaning, pigs were randomly allotted to 1 of 6 dietary treatments with 4 or 5 pigs per pen and 12 replications per treatment. Dietary treatments were arranged in a one-way treatment structure with diets containing different protein sources; enzymatically treated soybean meal (HP 300; Hamlet Protein, Findlay, OH), spray-dried bovine plasma (APC Corp, Ankeny, IA), fermented soybean meal (ME-PRO; Prairie Aquatech, Brookings, SD) with or without fish solubles (TASA, Lima, Peru), …

Characterizing Variation In Nursery Pig Growth Performance Based On Different Allotment Strategies, Jenna J. Bromm, Mike D. Tokach, Jason C. Woodworth, Robert D. Goodband, Joel M. Derouchey, Jordan T. Gebhardt
Kansas Agricultural Experiment Station Research Reports
A total of 360 pigs (200 × 400, DNA; initially 13.8 ± 1.83 lb BW) were used in a 42-d nursery trial to evaluate multiple procedures to allot pigs to pens and pens to treatment in swine nursery research. At placement, pigs were randomly assigned to 1 of 3 different allotment strategies. For the first strategy (random), pigs were allotted to pens using a completely randomized design. For strategy 2 (body weight distribution), pigs were sorted by body weight into 1 of 5 groups. Pigs were then randomly assigned to pen so there was 1 pig from each weight group …

Kansas Agricultural Experiment Station Research Reports
A total of 360 pigs (DNA 200 × 400; initially 13.8 ± 1.83 lb BW) were used in a 42-d nursery trial to determine the effects of the addition of an environmental enrichment, in the form of ropes tied to the feeder dividers, on feed intake and growth performance of weanling pigs. Pigs were weaned at approximately 21-d of age and randomly assigned to 1 of 2 treatments with 5 pigs per pen and 36 pens per treatment. At placement, a rope was secured to each of the dividers in the feed pans of the feeder (3 ropes/feeder) and remained …

Ensley
Kansas Agricultural Experiment Station Research Reports
Three hundred-fifty pigs (initially 26.2 ± 1.23 lb) were used to evaluate the effects of bone and analytical methods on the assessment of bone mineralization response to dietary P and vitamin D in nursery pigs. Pens of pigs (5 or 6 pigs/pen) were randomized to 6 dietary treatments in a randomized complete block design with 10 pens per treatment. Treatments were formulated to have varying levels of P, phytase, and vitamin D to provide differences in bone characteristics. After feeding diets for 28 d, eight pigs per treatment were euthanized for bone, blood, and urine analysis. The response to treatment …
Prevalence Of Escherichia Coli In A Swine Nursery Facility Pre- And Post-Disinfection, Macie E. Reeb, Kellen Habib, Jason C. Woodworth, Joel M. Derouchey, Mike D. Tokach, Robert D. Goodband, Jordan T. Gebhardt, Sara E. Gragg
Prevalence Of Escherichia Coli In A Swine Nursery Facility Pre- And Post-Disinfection, Macie E. Reeb, Kellen Habib, Jason C. Woodworth, Joel M. Derouchey, Mike D. Tokach, Robert D. Goodband, Jordan T. Gebhardt, Sara E. Gragg
Kansas Agricultural Experiment Station Research Reports
During the spring of 2021, the Kansas State University Swine Early Wean Facility (SEW) experienced a notable increase in piglet morbidity and mortality. Piglet diarrhea was observed approximately 2 to 3 weeks post-weaning along with an increase in number of sudden mortalities. Necropsy samples were collected and confirmed for clinical diagnosis ofEscherichia coliK88 infection by the Kansas State University Veterinary Diagnostic Laboratory.E. coliK88 can negatively impact performance of pigs and typically manifests as diarrhea, which can continue until death because of severe dehydration and metabolic acidosis or from terminal septicemia. Once present,E. coli, including …

Kansas Agricultural Experiment Station Research Reports
A total of 350 weanling barrows (DNA 200 × 400, DNA; initially 13.0 ± 0.08 lb) were used in a 38-d study to evaluate the effects of different benzoic acid feeding strategies on nursery growth performance and fecal dry matter. Pigs were randomly assigned to pens (5 pigs per pen) and pens were allotted to 1 of 5 dietary treatments with 14 pens per treatment. Diets were fed in 3 phases: phase 1 from weaning to d 10, phase 2 from d 10 to 18, and phase 3 from d 18 to 38. Dietary treatments were formulated to provide 0, …

A total of 320 pigs (DNA 241 × 600; initially 26.2 ± 0.48 lb BW) were used in a 21-d growth study to determine the available P (aP) release curve for Smizyme TS G5 2,500 (Barentz, Woodbury, MN). 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 8 dietary treatments on d 18 post-weaning, considered d 0 of the study. Dietary treatments were derived from a single basal diet and ingredients including phytase, monocalcium P, limestone, …
