This experiment was conducted to determine the optimum feeding strategy of a modified corn protein product (MCP; P4000; Cargill Starches, Sweeteners, & Texturizers, Blair, NE) on growth performance and fecal dry matter of nursery pigs. A total of 360 barrows (DNA 200 × 400; initially 12.0 ± 0.14 lb) were used in a 42-d growth trial. Pigs were weaned at approximately 21 d of age, randomly allotted to pens in 1 of 2 weight blocks based on initial BW (initially 10.8 and 13.2 lb), and then allotted to 1 of 6 dietary treatments in a completely randomized design. There were …

Effect Of Feed Form, Corn Particle Size, And Extrusion Of Corn On Broiler Performance, Marut Saensukjaroenphon, Caitlin E. Evans, Cassandra K. Jones, Charles R. Stark, Chad B. Paulk
Kansas Agricultural Experiment Station Research Reports
The pelleting and extrusion processes use both thermal and mechanical energies to alter the crystalline structure of the starch granule, which makes it more digestible than raw starch. The particle size of the ground corn particle in the diet also affects the rate at which gelatinization occurs in the extrusion process. There is limited research on broiler performance when feeding diets that contain different particle sizes of corn prior to extrusion. The objective of this study was to determine the effect of feed form, corn particle size and the extrusion of corn on growth performance of 21-d-old broiler chicks. To …

Kansas Agricultural Experiment Station Research Reports
The objective of this study was to determine the effects of whole corn moisture and hammermill screen size on subsequent ground corn moisture, particle size, and flow- ability. Whole yellow dent #2 corn was used for this experiment. Treatments were arranged as a 2 × 2 factorial design with two moisture concentrations (as-received and high) each ground using 2 hammermill screen sizes (1/8 and 1/4 in). Corn was ground using a laboratory scale 1.5 HP Bliss Hammermill (Model 6K630B) at 3 separate time points to create 3 replications per treatment. Increasing initial whole corn moisture was accomplished by adding 5% …

Kansas Agricultural Experiment Station Research Reports
Distillers grains, a by-product of the ethanol industry, have tremendous potential as an economical and nutritious supplement for grazing cattle. Distillers grains contain a high concentration of protein (25 to 30%), with more than two-thirds escaping degradation in the rumen, which makes it an excellent supplement for younger cattle. Recent advancements in the ethanol manufacturing process have resulted in extraction of a greater amount of fat; therefore, creating distillers grains that may contain less energy than corn. This research was conducted to compare performance of stocker cattle supplemented with corn or DDG at 0.5% body weight per head daily while …

Two experiments were conducted to determine the standardized ileal digestibility (SID) of amino acids in a high-lysine sorghum cultivar, followed by a growth trial to determine the effect of this sorghum on pig performance using increasing additions of feed-grade amino acids at the expense of soybean meal. In Exp. 1, ten growing barrows (initially 57.1 lb; Line 359 × 1050; PIC, Hendersonville, TN) were surgically fitted with a T-cannula at the terminal ileum and randomly assigned to 1 of 5 test diets in a 5-period, cross-over design. Experimental diets consisted of a corn-based diet, a diet containing high-lysine sorghum, or …

Cleaning Reduces Mycotoxin Contamination In Corn, A. Yoder, M. D. Tokach, J. M. Derouchey, C. B. Paulk, C. R. Stark, C. K. Jones
Kansas Agricultural Experiment Station Research Reports
A single load of corn naturally contaminated with aflatoxin (1,074 ppb), fumonisin (8.3 ppm), and ochratoxin A (206 ppb) was procured from central Oklahoma to evaluate the role of cleaning to remove mycotoxin contamination in corn. Corn was divided into twenty 333-lb lots, which were then cleaned using an EBM Gentle Roll corn cleaner to remove overs (material>1/2 inches) and unders (material<3/16 inches). The resultant 4 treatments included: 1) uncleaned corn; 2) overs from cleaned corn; 3) cleaned corn; and 4) unders from cleaned corn. Samples of each fraction were analyzed for mycotoxin content using multiclass liquid chromatography tandem mass spectrometry.
Cleaning generated approximately 6% screenings (unders + overs), and reduced (P<0.05) aflatoxin by an average of 26%. Cleaning also reduced (P<0.05) fumonisin by 45%, but did not impact ochratoxin A. Unders had nearly 4 times the aflatoxin and 7.5 times the fumonisin as the uncleaned corn. In conclusion, cleaning corn may substantially reduce mycotoxin contamination, but the resultant screenings should be used cautiously.

A total of 288 pigs (PIC 327×1050; initially 101.1 lb) were used in a 90-d study with 8 pigs per pen and 6 pens per treatment. Treatments were arranged in a 2 × 3 factorial with main effects of grain source (sorghum vs. corn) and crystalline AA supplementation (low, medium, or high). Amino acids ratios to Lys as well as standardized ileal digestibility coefficients used were set by NRC (2012). All diets were formulated …

Effects Of Varying Methodologies On Grain Particle Size Analysis, J. R. Kalivoda, C. K. Jones, C. R. Stark
Kansas Agricultural Experiment Station Research Reports
Particle size reduction is an important component of feed manufacturing that impacts pellet quality, feed flowability, and pig feed efficiency. The correct determination of particle size is important for feed manufacturers, nutritionists, and pork producers to meet target specifications. The current method for determining the geometric mean diameter (dgw) and geometric standard deviation (Sgw) of grains has been published by the ANSI/ASAE S319.4. This method controls many variables, including the suggested quantity of initial material and the type, number, and size of sieves. However, the method allows for variation in shake time, sieve agitators, and the use of a flow …
