Feeding Nucleotides With Corn Germ Meal Or Dried Corn Distillers Grains Does Not Promote Growth Performance Of Receiving And Growing Calves, M. L. Detray, S. P. Montgomery, E. Titgemeyer, A. E. Wertz-Lutz, Christopher Vahl, A. T. Schilling, W. R. Hollenbeck, Dale Blasi

Kansas Agricultural Experiment Station Research Reports

Corn germ meal is often used in swine and poultry diets, but very little information exists on the effects on beef cattle and on newly arrived stressed cattle. When formulating receiving and growing diets, calf health and stress are important factors to consider. Including nucleotides, an immune-boosting feed additive may aid in gastrointestinal health of an animal and furthermore improve growth performance. The objective of these experiments was to determine: 1) the effects of corn germ meal in comparison to dried corn distillers grains on growth performance and 2) the effects of nucleotides on growth performance, by receiving and growing ...

Particle Size Of Dry-Rolled Corn Affects Starch Digestibility But Not Feedlot Performance, E. F. Schwandt, J. Wagner, T. Engle, S. J. Bartle, D. U. Thomson, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Dry-rolling corn is a common practice in feedlots located in the Midwestern and Northern Plains regions of the United States. Optimizing total digestive tract starch utilization in diets containing dry-rolled corn is essential for maximizing efficiency. However, recommendations often suggest that grain be coarsely cracked to avoid producing an excessive amount of fine material that could potentially increase the rate of fermentation, reduce rumen pH, and cause digestive disturbances.

Wet distillers byproducts may be effectively used as a protein and energy source for feedlot finishing cattle and can replace a portion of the dry-rolled corn in the diet. The average ...

Kansas Agricultural Experiment Station Research Reports

An inherent challenge of long hauled, highly stressed calves is decreased feed intake upon destination arrival. Highly stressed, newly received stocker calves not consuming adequate amounts of energy are prone to a variety of disorders such as Bovine Respiratory Disease Complex and decreased performance throughout the feeding period. One mechanism that can be used to increase energy intake upon arrival is to make the diet more energy dense. Often times, this is accomplished by the addition of cereal grains high in fermentable carbohydrate including starch. Unfortunately, this has also been linked to increasing morbidity due to metabolic disorders. The goal ...

A Survey Of Dry Processed Corn Particle Size And Fecal Starch In Midwestern U.S. Feedlots, E. F. Schwandt, D. U. Thomson, S. J. Bartle, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Optimizing grain processing practices in cattle feeding operations is critical to reaching maximum feed utilization efficiency. An increased degree of grain processing has consistently shown improved dry matter and starch digestibility; however, it exists with conflicting results on improving performance in finishing cattle. These inconsistencies are likely due to diet composition, such as roughage and co-product level, that could offset the effects of reduced particle size on rate of fermentation thus reducing the risk of digestive dysfunction.

Finishing diets are commonly formulated with processed grain to increase utilization of starch and improve animal performance. Processing methods including steam-flaking, grinding, or ...


Tenderness, Juiciness, And Flavor Contribute To The Overall Consumer Beef Eating Experience, L. N. Drey, T. G. O'Quinn Jan 2017

Tenderness, Juiciness, And Flavor Contribute To The Overall Consumer Beef Eating Experience, L. N. Drey, T. G. O'Quinn

Kansas Agricultural Experiment Station Research Reports

Overall beef palatability can be attributed to three primary traits, tenderness, juiciness, and flavor, as well as the interaction among these traits (Smith and Carpenter, 1974). Multiple authors have worked to identify which of these palatability traits contributes the most to overall eating satisfaction and have historically identified tenderness as the most important palatability trait (Savell et al., 1987; Miller et al., 1995a; Savell et al., 1999; Egan et al., 2001). Overall eating quality of beef steaks may excel at one or even two of these traits, yet fail to meet consumer eating expectations due to the unsatisfactory level of ...
