Effects of diet bulk density on mixing uniformity

Thomas, Lori L.; Stark, Charles R.; Fahrenholtz, C. H.; Coble, Kyle F.; Hayashi, S.; Saensukjaroenphon, Marut; Woodworth, Jason C.; Goodband, Robert D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2015-04-26)

The objective of this study was to determine how the time required to create a uniformly mixed batch of feed is influenced by diets that differ in bulk density. Three 60-lb batches of a corn-soybean meal–based diet (high ...
Effects of electrostatic particle ionization on air quality, emissions, and growth performance of pigs housed in a thermo-regulated facility

De Jong, Jon A.; Card, Korrin N.; DeRouchey, Joel M.; Baumgartner, M.; Tomlinson, Peter J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2015-04-26)

Two identical 200-head nurseries at the Kansas State University Segregated Early Weaning Facility were used for 5 consecutive all-in, all-out groups to determine the effect of electrostatic particle ionization (EPI) on ...
Determining the optimal sampling method to estimate the mean and standard deviation of pig body weights within a population

Paulk, Chad B.; Tokach, Michael D.; Dritz, Steven S.; Nelssen, Jim L.; DeRouchey, Joel M.; Goodband, Robert D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2015-04-26)

The accuracy and precision of pig subsampling methods can determine the swine producer’s ability to sell pigs at optimal market BW and reduce economic discounts. The first objective of this experiment was to determine ...
Formation of fines during the pelleted feed manufacturing process and the resulting differences in nutrient composition of fines and pellets

De Jong, Jon A.; DeRouchey, Joel M.; Tokach, Michael D.; Goodband, Robert D.; Woodworth, Jason C.; Dritz, Steven S.; Erceg, Jake A.; McKinney, L.; Smith, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2015-04-26)

A 3-wk study was conducted at a commercial feed mill in northwest Iowa to determine where the formation of fines occurs during pelleted feed manufacturing and if differences are present in nutrient composition between ...
Effects of different feed mills and conditioning temperature of pelleted diets on nursery pig performance and feed preference from 14 to 50 lb

De Jong, Jon A.; DeRouchey, Joel M.; Tokach, Michael D.; Goodband, Robert D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2015-04-26)

A total of 644 pigs (PIC 1050 or 327 × 1050, initial BW~14 lb) were used in 3 experiments to determine possible explanations for poorer pig performance in previous studies with pigs fed pelleted diets compared with those ...
