Kansas Agricultural Experiment Station Research Reports

Crude glycerol is a by-product of the biofuels industry, which has the potential to be used as a feed ingredient in animal diets. However, little is known about glycerol’s nutritional value or how it impacts feed quality and feed processing efficiency. Three experiments were conducted to evaluate the effects of glycerol on production efficiency of a pellet mill. In all three experiments, diets were manufactured, pelleted, and data collected at the KSU Grain Science Feed Mill. All diets were steam conditioned to 85°F and pelleted at 150°F using a CPM pellet mill equipped with a 4 mm × 32 mm …

Comparison Of Feed Efficiency Rankings Of Heifers Fed Low And High Energy Dense Diets, J.A. Christopher, T.T. Marston Jan 2007

Comparison Of Feed Efficiency Rankings Of Heifers Fed Low And High Energy Dense Diets, J.A. Christopher, T.T. Marston

Kansas Agricultural Experiment Station Research Reports

Concepts related to energy efficiency in cattle have been the basis for many research projects. Even though differences in individuals have long been recognized, little effort has been focused on the causes of the observed variations. The concept of residual feed intake was first introduced in 1963, and is calculated as the difference between actual feed intake by an animal and its expected feed intake based on body weight and growth rate. Residual feed intakes are phenotypically independent of the production traits used to calculate expected feed intake. Consequently, residual feed intake values can be useful in comparing individuals differing …

Effects Of Increasing Added Choice White Grease In Corn And Sorghum-Based Diets On Growth Performance And Fat Quality Characteristics Of Finishing Pigs (2007), J M. Benz, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz Jan 2007

Effects Of Increasing Added Choice White Grease In Corn And Sorghum-Based Diets On Growth Performance And Fat Quality Characteristics Of Finishing Pigs (2007), J M. Benz, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

One hundred twenty crossbred barrows and gilts (TR4 × 1050) with an initial weight of 119.9 lb were used in an 83-d experiment to evaluate the effects of increasing added fat to corn or sorghum-based diets on growth performance and fat quality characteristics of finishing pigs. Treatments were arranged in a 2 × 2 × 3 factorial based on grain source (corn or sorghum), gender, and added fat (0, 2.5, or 5% choice white grease, CWG). At the end of the trial, jowl fat and backfat samples were collected. Pigs fed sorghum-based diets had increased (P<0.01) ADG compared with pigs fed corn-based diets. Pigs fed increasing CWG had increased (P<0.01) ADG. Pigs fed corn-based diets tended to have improved (P<0.06) dressing percentage, 10th rib BF, and percentage lean when compared with pigs fed sorghum-based diets. Barrows tended to have greater (P<0.06) dressing percentage and decreased (P<0.07) percentage lean when compared to gilts. Pigs fed increasing CWG had increased (P<0.02) 10th rib backfat, tended to have increased (P<0.08) hot carcass weight, and tended to have decreased (P<0.07) percentage lean. There was a fat level by grain source interaction (P<0.03) for percent C 18:2 fatty acids and iodine value in jowl fat. The interaction was due to the greatest increase in IV and percentage C 18:2 fatty acids occurring when CWG was increased from 2.5 to 5% for corn-based diets, while the greatest increase was from 0 to 2.5% CWG for sorghum-based diets. Despite this interaction, adding CWG increased (linear, P<0.02) percentage C 18:2 fatty acids and iodine value in jowl fat. Pigs fed corn-based diets had increased (P<0.01) iodine values and percentage C 18:2 fatty acids in jowl fat and backfat compared with pigs fed sorghum-based diets. Increasing dietary CWG increased (P<0.01) iodine value in jowl fat and backfat, increased (P<0.01) percentage C 18:2 fatty acids in backfat, tended to increase (P<0.06) percentage 18:2 fatty acids in jowl fat, and decreased (P<0.01) percentage saturated fatty acids in jowl fat and backfat. In summary, substituting sorghum for corn in diets for finishing pigs can be an effective way to reduce iodine value without affecting growth.; Swine Day, 2007, Kansas State University, Manhattan, KS, 2007

Kansas Agricultural Experiment Station Research Reports

One of the challenges regarding implementation of a national animal identification system is the logistics of reading and reporting EID (electronic identification) tag numbers as cattle move through the production cycle. Many small producers would have difficulty justifying the investment required to install an RFID (radio frequency identification) reader system that would only be used seasonally to track relatively small numbers of cattle that are entering commerce. A proposed solution to this issue is to install an RFID reader on commercial cattle trailers so that cattle can have EID tags read as they are loaded and unloaded during transport from …

Gnrh Removal In The 7-11 Co-Synch For Timed Insemination Of Beef Heifers, D.R. Eborn, David M. Grieger

Kansas Agricultural Experiment Station Research Reports

The use of artificial insemination can improve genetics, shorten the calving season, and increase weaning weights by having more calves born earlier in the breeding season. Reasons that this technology has not been used by many producers may include poor conception rates, time, and cost. Research has been directed at shortening the synchronization time and controlling time of ovulation to eliminate estrous detection using a timed artificial insemination. Use of a progestin, like the Eazi-Breed CIDR or melengestrol acetate (MGA), is desirable because they are effective in synchronizing estrus and they can also induce cyclicity in anestrus or prepubertal females. …

Grain Processing Reduces E. Coli O157 In Feedlot Cattle, J.T. Fox, M.E. Jacob, S.L. Reinstein, James S. Drouillard, Tiruvoor G. Nagaraja Jan 2007

Grain Processing Reduces E. Coli O157 In Feedlot Cattle, J.T. Fox, M.E. Jacob, S.L. Reinstein, James S. Drouillard, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Escherichia coli O157 is an important food-borne pathogen for which the gastrointestinal tract of cattle is the major reservoir. Fecal shedding of E. coli O157 in cattle reflects the ability of the organism to persist in or colonize the gastrointestinal tract. Evidence suggests that the site of persistence or colonization is in the hindgut and not the rumen. Although the reasons are not known, it is likely that the ecosystem of the hindgut is more hospitable than the rumen. Therefore, we hypothesize that dietary factors that promote supply of substrates (starch, fiber, protein, or lipids) to the hindgut will have …

Kansas Agricultural Experiment Station Research Reports

Treating food with ionizing radiation improves product safety and helps maintain quality. The main selling point of irradiated foods is that it is microbially safe. Beginning in October 2002, companies could petition the FDA for permission to use terms like "electronic pasteurization" on the labeling for irradiated foods. Consumers are already familiar with pasteurization and they associate the term with a safe product. There needs to be a protocol in place to test for irradiation to verify that products meet regulatory requirements. Being able to differentiate between irradiated and nonirradiated food will aid in proving the authenticity and safety of …

Ultrasound Sorting Increases Feedlot Profitability, A. Garmyn, Daniel W. Moser

Kansas Agricultural Experiment Station Research Reports

Feedlot managers often market entire pens as mixed groups, resulting in lower-quality, over-finished, or heavyweight carcasses. As the cattle industry has moved towards valuebased marketing systems, finding a costeffective tool that predicts future carcass merit and sorts cattle into outcome groups, thus producing a more uniform product at harvest, is of great interest to feedyard managers. The objective of this research was to determine the profitability of sorting feedlot cattle at reimplant time by using ultrasound and computer technology to group cattle into uniform market groups.

Energy Supply Affects Leucine Utilization By Growing Steers, G.F. Schroeder, E.S. Moore, Evan C. Titgemeyer Jan 2007

Energy Supply Affects Leucine Utilization By Growing Steers, G.F. Schroeder, E.S. Moore, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

In growing pigs, when protein supply is adequate, protein deposition increases with an increase in energy intake. However, when amino acid supply is limited, protein deposition does not respond to increases in energy intake. These relationships between energy, protein supply and protein deposition, which are observed in monogastric animals, have been described as protein- and energydependent phases of growth. These relationships indicate that energy supply does not affect the efficiency of amino acid utilization, allowing the assumption of a constant efficiency across a broad range of energy intake. Although this type of relationship is assumed for cattle by most of …

Limit-Feeding A High-Concentrate Diet May Alter Nutrient Absorption, J.O. Wallace, W.F. Miller, B.J. Johnson, Christopher D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Feeding newly arrived cattle is commonly characterized by a few days of feeding longstemmed hay followed by a series of step-up diets, wherein concentrate levels are increased to promote ruminal adaptation to a highconcentrate finishing diet. This is done to give the rumen microbes time to adjust to larger amounts of readily fermentable starches in cereal grains. Rumen epithelial adaptation may be achievable by limit-feeding a finishing diet, with gradual increases in feed intake, until the cattle are on full feed. If this can be achieved without causing ruminal disorders and days off feed, then the cost of feeding cattle …

Dried Distiller’S Grains Improve The Performance Of Beef Cattle Intensively Grazing Early Summer Bluestem Pasture, M. Epp, B. Barnhardt, A. Bryant, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Distiller's grains are byproducts of the production of ethanol from grains and are an excellent source of protein and energy for cattle. The most prevalent use of distiller's grains is in the finishing beef production sector. There is limited research available that has evaluated effectiveness of distiller's grains as a supplement for grazing beef cattle. Digestible protein content in grass begins to decrease in midsummer, resulting in lower average daily gains. The objective of this study was to measure the daily gain of yearling steers supplemented with different levels of dried distiller's grains while grazing doublestock Flint Hills pastures.

Optimizing Use Of Distiller’S Grains With Solubles (Dgs) In Finishing Cattle Diets, E.R. Loe, M.E. Corrigan, M.J. Quinn, Brandon E. Depenbusch, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Rapid expansion of the fuel ethanol industry has increased availability of distillery byproducts. Distiller's grains with solubles (DGS) are the predominant byproduct of fermenting grains to fuel ethanol. During this process, the majority of starch is removed from the grain, and residual components of the grain are concentrated into the distiller's byproduct. Distiller's grains with solubles contain the bran, which is high in fiber; the germ, which is high in fat; and the protein. Given the relatively high fiber content of DGS, it is conceivable that DGS could serve as a replacement for roughage in finishing diets. One of the …
