Comparative Value Of Dry-Rolled Corn, Distiller’S Dried Grains, And Wheat Middlings For Receiving Diets (1999), S.E. Ives, D.W. Anderson, R.H. Wessels, James S. Drouillard Jan 1999

Comparative Value Of Dry-Rolled Corn, Distiller’S Dried Grains, And Wheat Middlings For Receiving Diets (1999), S.E. Ives, D.W. Anderson, R.H. Wessels, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Two 28-day receiving experiments were conducted using 620 exotic x British cross steers to evaluate differences in growth performance, morbidity, and mortality when fed diets containing dry-rolled corn, distiller's dried grains with solubles, or wheat middlings. All diets contained approximately 60% concentrate and 40% roughage (alfalfa hay). Gain and efficiency tended to be poorer for cattle fed the wheat middling-based diet than for those fed corn. No notable differences were evident in terms of the percentage of cattle treated for respiratory disease. Feed intake and daily gain were improved slightly when corn was replaced by distiller's dried grains, but efficiency …

Effects Of Supplementing Limit-Fed, Wheat Middling-Based Diets With Either Soybean Meal Or Non-Enzymatically Browned Soybean Meal On Growing Steer Performance (1999), C.M. Coetzer, E. Coetzer, R.H. Wessels, James S. Drouillard Jan 1999

Effects Of Supplementing Limit-Fed, Wheat Middling-Based Diets With Either Soybean Meal Or Non-Enzymatically Browned Soybean Meal On Growing Steer Performance (1999), C.M. Coetzer, E. Coetzer, R.H. Wessels, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Seventy two individually fed Angus x Hereford steers (660 lb) were limit-fed, 16.7% CP wheat middling-based diets with 1.9 or 3.8 percentage units of additional CP from either soybean meal (SBM) or non-enzymatically browned soybean meal (NEBSBM). A limitfed, rolled corn-based diet (16.7% CP) also was included. Steers were fed once daily for 70 days at 2.25% of BW. The SBM provided 30% bypass protein, and NEBSBM provided 68%. Average daily gain and efficiency improved linearly with increasing level of NEBSBM (P<.05; ADG=2.482 + .106 (increase in % CP); feed to gain=6.26 - .22(increase in % CP)), but not with increasing levels of SBM. Steers fed the wheat middling diets had lower ADG and efficiency than those fed the corn control diet. These data suggest that bypass protein may be first limiting in highconcentrate, limit-fed growing diets composed predominantly of wheat middlings.

Effect Of Level Of Non-Enzymatically Browned Soybean Meal In Limit-Fed, Grain Sorghum Diets For Growing Heifers (1999), R.D. Hunter, James S. Drouillard, Evan C. Titgemeyer Jan 1999

Effect Of Level Of Non-Enzymatically Browned Soybean Meal In Limit-Fed, Grain Sorghum Diets For Growing Heifers (1999), R.D. Hunter, James S. Drouillard, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Grain sorghum-based diets were fed in a limit-feeding trial involving 72 heifers for 100 days. Heifers were fed one of four diets designed to provide 12.5%, 14.9%, 17.3%, and 19.6% crude protein. Protein levels in the diets were altered by providing up to 20% of the diet as non-enzymatically browned soybean meal (Soypassâ) at the expense of dry-rolled grain sorghum. Performance of heifers (gain and feed efficiency) tended (P=.15) to improve linearly as protein concentration of the diets was increased. The greatest improvements were observed at concentrations up to 17.3%.

Using Arsoy™ As A Protein Supplement In Growing Cattle Diets (1999), T.T. Marston, K.K. Kreikemeier, L.E. Wankel, G.L. Huck, T.J. Wistuba Jan 1999

Using Arsoy™ As A Protein Supplement In Growing Cattle Diets (1999), T.T. Marston, K.K. Kreikemeier, L.E. Wankel, G.L. Huck, T.J. Wistuba

Kansas Agricultural Experiment Station Research Reports

Arsoy™ Soybean Feed is a by-product from the manufacture of soy protein isolate. It contains nearly 30% crude protein, but there is little documentation about its feeding value. Therefore, we fed basal growing diets of corn silage and stover to 196 crossbred heifers and supplemented those diets with soybean meal, Arsoy, or a combination of soybean meal and high moisture corn to determine the feeding value of Arsoy. Our results suggest that Arsoy can be substituted for soybean meal in growing cattle diets, without any negative impact on animal performance, dry matter intake, or feed efficiency.

Dehydrated Paunch And Vegetable By-Products For Growing Beef Cattle (1999), T.A. Nutsch, R.D. Hunter, James S. Drouillard Jan 1999

Dehydrated Paunch And Vegetable By-Products For Growing Beef Cattle (1999), T.A. Nutsch, R.D. Hunter, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Crossbred beef heifers (avg wt 653 lb) were used in a feeding experiment to determine the relative feed value of dried paunch content, two separate vegetable processing by-products, and combinations of by-products with dryrolled corn. Consumption of the vegetable byproduct diets, both of which contained a high percentage of fat, was less than expected. Performance of cattle fed the by-product diets was less than that of cattle fed high-energy diets comprised of corn. However, when combined with corn, the vegetable by-product yielded performance similar to that of corn alone.

Soy Molasses As A Feed Ingredient For Finishing Cattle (1999), C.K. Schoenholz, R.D. Hunter, T.A. Nutsch, James S. Drouillard Jan 1999

Soy Molasses As A Feed Ingredient For Finishing Cattle (1999), C.K. Schoenholz, R.D. Hunter, T.A. Nutsch, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Eighty Angus x Hereford cross steers were used in an individual feeding study to compare soybean molasses (a by-product of soybean meal manufacture) and soybean meal as ingredients in finishing diets containing flaked corn or a combination of high-moisture corn and dryrolled corn. Supplementation with soy molasses resulted in higher (P<.05) feed intakes in the cattle fed the high-moisture corn diet but had no effect on intakes of cattle fed the flaked diets. No such changes were noted for supplementation with soybean meal. In general, carcass traits were not influenced by level or type of supplement. Soy molasses appears to have feed value equal to or greater than that of soybean meal when compared on a protein basis. Its value as a source of supplemental nutrients appears to be greater in steam-flaked diets than in high-moisture diets.

Role Of Methionine As A Methyl Group Donor In Cattle (1999), C.A. Löest, R.H. Greenwood, Evan C. Titgemeyer Jan 1999

Role Of Methionine As A Methyl Group Donor In Cattle (1999), C.A. Löest, R.H. Greenwood, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Holstein steers were used in two 5 x 5 Latin square experiments to evaluate the sparing of methionine by alternative sources of methyl groups (betaine or choline). Steers were housed in metabolism crates and limit fed a diet high in rumen degradable protein. To increase energy supply, volatile fatty acids were infused into the rumens, and glucose was infused into the abomasum. An amino acid mixture, limiting in methionine, was infused abomasally to ensure that non-sulfur amino acids did not limit protein synthesis. Treatments for Exp. 1 were abomasal infusion of 1) water (control), 2) 2 g/day additional L-methionine, 3) …

Effect Of Ruminal Versus Postruminal Administration Of Degradable Protein On Utilization Of Low-Quality Forage By Beef Steers (1999), C.A. Bandyk, R.C. Cochran, T.A. Wickersham, C.G. Farmer, Evan C. Titgemeyer Jan 1999

Effect Of Ruminal Versus Postruminal Administration Of Degradable Protein On Utilization Of Low-Quality Forage By Beef Steers (1999), C.A. Bandyk, R.C. Cochran, T.A. Wickersham, C.G. Farmer, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Twelve ruminally fistulated steers were used to evaluate the effects of supplying a highly degradable protein source (casein) both ruminally and postruminally on intake and digestibility of low-quality native hay. Both protein supplementations substantially increased voluntary intake, organic matter digestion, rate of passage, ruminal ammonia, and blood urea concentrations, but intakes were considerably greater when protein was given ruminally as opposed to postruminally.

Wheat Bran And Second Clears As Supplemental Energy Sources For Beef Cows Grazing Winter Pasture (1999), C.G. Farmer, R.C. Cochran, D.D. Simms, J.S. Heldt, C.P. Mathis

Kansas Agricultural Experiment Station Research Reports

Ninety spring-calving Hereford x Angus cows grazing low-quality, tallgrass-prairie forage during the winter were fed 5 lb/day of a supplement containing combinations of wheat bran (high in digestible fiber) and second clears (high in starch). The by-product combinations accounted for 47 to 49% of each supplement, as follows: 1) 100% wheat bran; 2) 67% wheat bran, 33% second clears; and 3) 33% wheat bran, 67% second clears. Cow performance was measured by changes in body weight and body condition score. The combinations of wheat bran and second clears had no significant effects on cow performance, calf birth weights, calf performance, …

Impacts Of Wheat Milling By-Products In Supplements On The Intake And Digestion Of Steers Consuming Low-Quality Forage (1999), C.G. Farmer, R.C. Cochran, D.D. Simms, J.S. Heldt, C.P. Mathis Jan 1999

Impacts Of Wheat Milling By-Products In Supplements On The Intake And Digestion Of Steers Consuming Low-Quality Forage (1999), C.G. Farmer, R.C. Cochran, D.D. Simms, J.S. Heldt, C.P. Mathis

Kansas Agricultural Experiment Station Research Reports

Sixteen ruminally fistulated steers were used to evaluate the effects of feeding supplements containing combinations of two wheat-milling by-products on forage intake, digestibility, and ruminal characteristics. The by-products accounted for 47 to 49% of each supplement and were as follows: 1) 100% wheat bran; 2) 67% wheat bran, 33% second clears; and 3) 33% wheat bran, 67% second clears. All supplements contained about 30% CP. Compared with unsupplemented controls, forage intake and digestibility were significantly higher for supplemented steers. However, no differences occurred among by-product treatments. In conclusion, if the protein content is adequate, the choice of bran (high digestible …

Effect Of Interseeding Legumes Into Endophyte-Infected Tall Fescue Pastures On Forage Production And Steer Performance (1999), Lyle W. Lomas, Joseph L. Moyer, Gary L. Kilgore Jan 1999

Effect Of Interseeding Legumes Into Endophyte-Infected Tall Fescue Pastures On Forage Production And Steer Performance (1999), Lyle W. Lomas, Joseph L. Moyer, Gary L. Kilgore

Kansas Agricultural Experiment Station Research Reports

A total of 135 steers grazed high-endophyte tall fescue pasture interseeded with either lespedeza, red clover, or ladino clover during 1995, 1996, and 1997. Legume cover, forage dry matter production, grazing steer performance, and subsequent feedlot performance were measured. Legume treatment caused no differences in forage availability. Grazing gains corresponded to the amount of legume coverage present. Results of this study indicate that interseeding high endophyte fescue pastures with ladino clover produced higher stocker gains during the grazing phase than interseeding with lespedeza or red clover. Legume treatment had no effect on subsequent finishing gains.

Nutritional Evaluation Of Corn And Sorghum Crop Residues (1999), R.K. Taylor, Gary L. Kilgore, James J. Higgins, Dale A. Blasi, Stewart R. Duncan Jan 1999

Nutritional Evaluation Of Corn And Sorghum Crop Residues (1999), R.K. Taylor, Gary L. Kilgore, James J. Higgins, Dale A. Blasi, Stewart R. Duncan

Kansas Agricultural Experiment Station Research Reports

Crop residue samples from 22 grazed and nongrazed corn and sorghum residue fields across Kansas were collected every 2 weeks during the 1997/98 winter feeding season to evaluate quality and yield. Corn residue averaged about 2 ½ tons of total dry matter (DM)/acre, with the leaf fraction (attached and unattached) constituting about 60% of that residue. Unattached leaves represented 85% of the total leaf DM. Yield estimates for sorghum residue averaged over 2 tons/ acre. The stem component represented 55 to 60% of the total DM collected, and about 58% of the leaves remained attached to the stem.

Effect Of Date Of Harvest On The Yield And Nutritional Quality Of Native Grass Hay (1999), J.C. Baker, S.R. Tonn, S.I. Paisley, David E. Kehler, Dale A. Blasi Jan 1999

Effect Of Date Of Harvest On The Yield And Nutritional Quality Of Native Grass Hay (1999), J.C. Baker, S.R. Tonn, S.I. Paisley, David E. Kehler, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Native grass hay meadows in three Kansas Flint Hills counties were sampled at 2-week intervals during the 1997 and 1998 growing seasons to determine the effect of harvest date on forage quality and dry matter (DM) yield. Each sample was weighed and analyzed for crude protein (CP), acid detergent fiber (ADF), and phosphorus (PHOS). The CP and PHOS contents declined, whereas ADF and DM yield increased as harvest date progressed. Although CP, ADF and DM yield were related highly to harvest date, the association for PHOS content was only moderate. Because harvest date of native grass hay can significantly influence …
