Woodworth, Joel M. Derouchey, Steve S. Dritz, Mike D. Tokach, Robert D. Goodband, Hilda Calderon Cartagena
Kansas Agricultural Experiment Station Research Reports
A multi-trial analysis was conducted to evaluate the effects of pharmacological levels of added IntelliBond Copper (IBC) on growing-finishing pig growth performance and carcass characteristics compared to pigs fed control diets containing typical additions of copper from a trace mineral premix. Data with 331 observations within 8 trials were included in the final database. Inclusion rates for IBC were either 150 (7 trials), or 200 (1 trial) ppm. Pigs fed IBC throughout the entire grow-finish period had greater (P<0.05) overall ADG, ADFI, and final BW and tended (P= 0.085) to be more efficient than pigs fed control diets. There was no evidence for differences (P …

Summary Of Methodology Used In Enterotoxigenic Escherichia Coli (Etec) Challenge Experiments In Weanling Pigs And Quantitative Assessment Of Observed Variability, Payton L. Dahmer, Joel M. Derouchey, Jordan T. Gebhardt, Chad B. Paulk, Cassandra K. Jones
Kansas Agricultural Experiment Station Research Reports
Post-weaning diarrhea in pigs can be caused by the F4 or F18 strains of enterotoxigenicEscherichia coli(ETEC). To evaluate interventions for ETEC, experimental infection via a challenge model is critical. To our knowledge, there is a lack of explanation for the variability in responses observed across ETEC challenge studies. Our objective was to quantitatively summarize the responses and variability among recent ETEC challenge studies and develop a tool for sample size calculation. The most widely evaluated response criteria across ETEC challenge studies are growth performance, fecal consistency and bacterial shedding, intestinal morphology, and immune responses. Factors that contribute to …

This trial was conducted to evaluate the optimum scale head settings for LeeO scale systems to balance accuracy, precision, and efficiency in weighing pigs. LeeO scales allow for the adjustment of both stabilization time (mSec) and stabilization weight (g). The pig weight that is accepted by the technology is only registered after staying within the set stabilization weight for the set stabilization time. Prior to beginning animal research, precision and accuracy were assessed for two scales. The nursery scale used a 25-lb test weight and the finisher scale used a 50-lb test weight.

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 …

Kansas Agricultural Experiment Station Research Reports
A total of 1,512 pigs (Line 337 × 1050 PIC; initially 10.4 lb) were used to evaluate lactose level and whey permeate form on nursery pig performance in a commercial environment. Pigs were weaned at approximately 19 d of age and were allotted to 1 of 4 dietary treatments arranged in a 2 × 2 factorial utilizing low or high lactose levels with either granular whey permeate (Dairylac 80, International Ingredients Corporation, Fenton, MO) or spray-dried whey permeate. There were 27 pigs per pen and 14 replications per treatment. Pigs were fed experimental diets in two phases with phase 1 …

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 …

The objective of these experiments was to evaluate the impact of varying SID Trp:Lys ratios on growth performance, removals, and mortality rates of PIC 337 × 1050 finishing pigs. In each experiment, pens of pigs were blocked by BW and randomly assigned to 1 of 5 dietary treatments in a randomized complete block design with 22 to 27 pigs per pen and 6 or 7 replications per treatment. In Exp. 1, 840 pigs (initially 101.2 ± 2.08 lb) were used from 101 to 161 lb. In Exp. 2, 801 pigs (initially 219.8 ± 3.44 lb) were used from 220 to …

A total of 2,160 mixed-gender pigs (PIC 337 × 1050; initially 54.8 ± 9.4 lb) were used in the 120-d study to compare feeding strategies (phase feeding vs. complete diet blending) at different SID Lys levels (90 vs. 100% of requirement estimates) on finishing pig growth performance, carcass characteristics, and economics. Pens of pigs were randomly assigned to 1 of 4 treatments following a completely randomized block design with barn and initial body weight as blocking factors. The treatments included two feeding programs, a 5-phase feeding strategy at either 90% (Phase-90) or 100% of SID Lys requirement estimates (Phase-100); or …

Pigs from 64 commercial sites across 14 production systems in the Midwest US were used to evaluate the baseline biological measurements used to determine bone mineralization. Three pigs were selected from each commercial site representing: 1) a clinically normal pig (healthy); 2) a pig with evidence of clinical lameness (lame); and 3) a pig from a hospital pen that is assumed to have recent low feed intake (unhealthy). Pigs ranged in age from nursery to market weight, with the three pigs sampled from each site representing the same age or phase of production. Blood, urine, metacarpal, fibula, 2nd rib, and …
