Effects Of Grinding Corn Through A 2-, 3-, Or 4-High Roller Mill On Pig Performance And Feed Preference Of 25- To 50-Lb Nursery Pigs, J. T. Gebhardt, J. A. De Jong, M. D. Tokach, J. C. Woodworth, J. M. Derouchey, R. D. Goodband, K. F. Coble, C. R. Stark, C. K. Jones, S. S. Dritz

A total of 410 pigs were used in two experiments to determine the effects of grinding corn through various roller mill configurations on feed preference and performance of nursery pigs.

In Exp. 1, 320 pigs (DNA 400 × 200, initially 23.6 lb) were randomly allotted to 1 of 4 dietary treatments with 16 pens per treatment and 5 pigs per pen for a 21-d growth trial. The 4 dietary treatments used the same corn-soybean meal-based formulation that was mixed from the same batch of ingredients. Corn was ground through the same 4-high roller mill, but using different roller configurations. Experimental …

Effects Of Grinding Corn Through A 2-, 3-, Or 4-High Roller Mill On Milling Characteristics, And Commercial Finishing Pig Growth Performance And Carcass Characteristics, J. T. Gebhardt, K. F.

A total of 922 pigs [PIC TR4 × (FAST Large white × PIC Landrace), initially 88.3 lb] were used in a 97-d experiment to determine the effects of grinding corn through various roller mill configurations on milling characteristics as well as growth performance and carcass characteristics of finishing pigs in a commercial setting. Pens were randomly allotted to 1 of 4 experimental treatments by initial BW with 11 pens per treatment and 21 pigs per pen. All diets were fed in 5 phases with the same corn-soybean meal-based diets containing 20% dried distiller’s grains with solubles. Experimental treatments included: (1) …

Evaluating The Accuracy Of The 3-Sieve Particle Size Analysis Method Compared To The 12-Sieve Method, G. E. Bokelman, S. C. Stewart, A. L. Baldridge, J. C. Woodworth, S. S. Dritz, J. R. Kalivoda, C. R. Stark, C. K. Jones

The 3-sieve particle size analysis method was developed to estimate the particle size of ground grain within feed mills without the time and expense required for a 12-sieve analysis. The 3-sieve method is more simplistic because it is hand-shaken and uses fewer sieves but has drawbacks because it is not as precise as the 12-sieve method. Because shaking is not automated, technician variation may impact results. Furthermore, the accuracy of the original 3-sieve method has been questioned because the method was developed for corn between 400 to 1,200μm, and the industry now grinds various grains more finely. Some …

Finely Grinding Cereal Grains In Pelleted Diets Offers Little Improvement In Nursery Pig Growth Performance, G. E. Bokelman, J. A. De Jong, J. R. Kalivoda, A. Yoder, C. R. Stark, J. C. Woodworth, C. K. Jones

Kansas Agricultural Experiment Station Research Reports

Five experiments were conducted to determine the effects of corn particle size and diet form on nursery pig performance and feed preference. In Exp. 1, 192 nursery pigs (PIC 327 × 1050; initially 14.7 lb and 26 d of age) were used in a 35-d experiment. Pens of pigs were balanced by BW and allotted to 1 of 4 treatments with 6 pigs per pen and 8 pens per treatment. The same corn and soybean meal-based diet formulation was used for all treatments. The 2 × 2 factorial consisted of the main effects of corn particle size (400 vs. 700 …
