Effect Of Sample Preparation And Extended Mix Times With Different Salt Particle Sizes On The Uniformity Of Mix Of A Corn-Soybean Meal Swine Diet, M. Saensukjaroenphon, C. K. Jones, C. H. Fahrenholz, C. R. Stark

Kansas Agricultural Experiment Station Research Reports

The uniformity of a feed mixture is determined from the coefficient of variation (CV) of 10 samples in a single batch of feed. The feed industry standard is a CV of less than 10% using a single source tracer, such as salt, trace minerals, or iron filings. The objectives of these experiments were to determine the effects of 1) extended mix time, 2) particle size of the marker, and 3) sample preparation on the CV in a corn-soybean meal swine diet. In Experiment 1, treatments were arranged in a 3 × 7 factorial with main effects of 3 salt particle …

The Effect Of Liquid Application Times, And Mixer Types With Different Wet Mix Times On Uniformity Of Mix, M. Saensukjaroenphon, C. K. Jones, C. H. Fahrenholz, C. R. Stark Jan 2016

The Effect Of Liquid Application Times, And Mixer Types With Different Wet Mix Times On Uniformity Of Mix, M. Saensukjaroenphon, C. K. Jones, C. H. Fahrenholz, C. R. Stark

Kansas Agricultural Experiment Station Research Reports

Liquid addition systems are often designed to add liquid ingredients with the shortest application time in order to increase the batching capacity and efficiency of the mixing process. The quantity of liquid that is added into the mixer affects batch cycle time, particularly when there is a programmed “wet mix” time, or mixing time after liquid application has completed. Shorter application time of liquids typically produces a larger droplet size, which may lead to greater clumping tendencies in the feed and less uniformity of liquid incorporation. Two experiments were conducted to determine the effect of liquid application time and wet …

Kansas Agricultural Experiment Station Research Reports

A total of 240 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, 2014, and 2015. Daily gains of steers that grazed MaxQ fescue, wheatbermudagrass, or wheat-crabgrass were similar (P>0.05) in 2010. The daily gains of steers that grazed wheat-bermudagrass or wheat-crabgrass were greater (P>0.05) than those that grazed MaxQ fescue in 2011 and 2012.

Evaluation Of Supplemental Energy Source For Grazing Stocker Cattle, L. W. Lomas, J. K. Farney, J. L. Moyer Jan 2016

Evaluation Of Supplemental Energy Source For Grazing Stocker Cattle, L. W. Lomas, J. K. Farney, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Seventy-two steers grazing smooth bromegrass pastures were used to evaluate the effects of supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics in 2014 and 2015. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as the primary source of energy. Supplements were formulated to provide the same quantity of protein and energy per head daily. Supplementation with the starch-based or fat-based supplement during the grazing phase resulted in higher (P<0.05) grazing gains than feeding no supplement during both years. In 2015, steers supplemented with the fat-based supplement had greater (P<0.05) grazing gains than those that received the starch-based supplement. In 2014, supplementation during the grazing phase had no effect (P>0.05) on finishing gain, feed intake, and feed:gain. Steers supplemented with the …

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas Jan 2016

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas

Kansas Agricultural Experiment Station Research Reports

Use of legumes in bermudagrass pastures has often increased summer cow gains. Forage production was greater where ladino clover was used in the Legume system than where Nitrogen (N) alone was used in the first sampling, but the reverse was true in midsummer. Estimated forage crude protein during 2015 was greater for the Legume than the Nitrogen system in the first and last samplings, but similar in mid-summer pasture. Cow performance over the season was increased 68% where legumes were used.

The Effect Of Enhancement On Trained Panel Beef Palatability Scores Is Dependent Upon Usda Quality Grade, K. V. Mckillip, A. K. Wilfong, J. M. Gonzalez, T. A. Houser, E. A. Boyle, J. A. Unruh, T. G. O'Quinn

Kansas Agricultural Experiment Station Research Reports

Quality grades are used to determine beef value. The U.S. Department of Agriculture grading system categorizes beef into levels of eating satisfaction with the highest being Prime and decreases until reaching the Canner quality grade. Currently the premium of Prime graded carcasses over Select is $16.73 (USDA, 2015). Traditionally, USDA Select cuts are known to have lower palatability ratings for juiciness, tenderness, and overall liking. Select steaks also fail to meet consumer eating expectations more than 33% of the time (Corbin, 2015). This failure rate represents a large cost for the industry. Product enhancement utilizing a water, salt, and phosphate …

Ruminally-Protected Lysine (Safegain) Improves Performance Of Growing Beef Cattle, V. A. Veloso, C. L. Van Bibber-Krueger, J. S. Drouillard Jan 2016

Ruminally-Protected Lysine (Safegain) Improves Performance Of Growing Beef Cattle, V. A. Veloso, C. L. Van Bibber-Krueger, J. S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Lysine frequently is cited as the first-limiting amino acid for cattle diets. Synthetic lysine, while routinely added to pig diets, is ineffective in fulfilling lysine requirements of cattle due to extensive degradation by microbes within the rumen. Lysine can be encapsulated with compounds, such as saturated fats, that minimize degradation by ruminal microbes, thereby assuring that a greater proportion of the amino acid is available for absorption post-ruminally. The purpose of this experiment was to measure the impact of SafeGain (H.J. Baker & Bro. Inc., Little Rock, AR), an encapsulated form of lysine sulfate, on rate of gain and feed …
