Influence Of Rumen Bypass Fat Fed In A Range Supplement On The Performance Of Cows And Calves Grazing Bluestem Range, L. Corah, B. Cochran, D. Harmon, T. Goehring

Kansas Agricultural Experiment Station Research Reports

Adding rumen bypass fat to a range supplement reproductive characteristics, cow weight and condition performance during a 43-day postpartum feeding period.


Effects Of Mga And Prostaglandin On Estrus Induction And Synchronization In Cows And Heifers, R.C. Perry, G.W. Boyd, T.B. Goehring, L.R. Corah Jan 1987

Effects Of Mga And Prostaglandin On Estrus Induction And Synchronization In Cows And Heifers, R.C. Perry, G.W. Boyd, T.B. Goehring, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Four trials were conducted to evaluate the effectiveness of Melegestrol Acetate (MGA ®) and prostaglandin (PGF) in inducing and synchronizing estrus. In trial 1, treated heifers were fed MGA for 7 days and given a PGF injection on either the first or last day of MGA feeding. The 7-day estrus response was higher (P<.01) for treated heifers than untreated controls. In trial 2, treated cows were fed MGA for 7 days and given a PGF Injection on the last day of MGA feeding or 13 days after the last day of MGA feeding. The 7-day estrus response was also higher (P<.01) in treated cows. In trial 3, 59 cows were fed MGA for 7 days followed by a PGF injection, and exposed to bulls for 66 days. The MGA-PGF treatment was ineffective in synchronizing estrus and hastening conception. In trial 4, feeding MGA for 7 days successfully synchronized estrus in. cycling cows, but first service conception rates were reduced by 10% in the Kansas study and by 16% in a four state study.


Effect Of Supplemental Protein:Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant Jan 1987

Effect Of Supplemental Protein:Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Feeding a low crude protein (12%) supplement depressed dormant bluestem range-grass fiber digestibility, whereas moderate (27%) and high (41 %) protein supplementation maintained forage digestibility and encouraged intake. Increased intake for moderate and high protein groups appeared to be associated with increased rumen dry matter and indigestible fiber fill.


Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas Jan 1987

Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas

Kansas Agricultural Experiment Station Research Reports

Whole-plant corn silages were treated with USO3M or Silo-Best Soluble® in one trial and with Garst M-74® in a second trial. In Trial 1 all three silages were well preserved and moderately stable in the air. USO3M silage lost less dry matter during fermentation than control or Silo-Best silages. Cattle fed the USO3M silage made 7.6% faster gains and were 5.2% more efficient than those fed the control silage. Cattle performance with the Silo-Best Soluble and control silages was similar. In trial 2, heifer gains were nearly identical for both control and Garst M-74 silages.


Effects Of Trenbolone Acetate And Zeranol Implants On Performance, Carcass, And Meat Traits Of Young Bulls And Steers, R.D. Johnson, Michael E. Dikeman Jan 1987

Effects Of Trenbolone Acetate And Zeranol Implants On Performance, Carcass, And Meat Traits Of Young Bulls And Steers, R.D. Johnson, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Implanting young bulls and steers with trenbolone acetate and zeranol (Ralgro ®) resulted in increased slaughter weights and carcasses that tended to have more marbling than those of control bulls. Furthermore, steaks from both implanted bulls and implanted steers tended to have less detectable connective tissue. Control bulls had larger scrotal circumferences and heavier testicle weights than implanted bulls. Other secondary sex characteristics were not affected, but in these bulls slaughtered at an average age of 13.6 months, sexual development was minimal. Implanting steers with trenbolone acetate and zeranol resulted in performance and carcass and meat quality slightly superior to ...


Compudose® Compared With Synovex-H® For Finishing Yearling Heifers, S.B. Laudert Jan 1987

Compudose® Compared With Synovex-H® For Finishing Yearling Heifers, S.B. Laudert

Kansas Agricultural Experiment Station Research Reports

Feedlot heifers implanted once with either Compudose® or Synovex-H® performed similarly, with daily gains of 3.16 vs 3.27 lbs, respectively. Compudose retention in the ear was 97.5%. Implant site abscess rate was 2.5% for Compudose and 13.7% for Synovex-H.


Effects Of Rumensin® Ruminal Delivery Devices In Grazing Cattle On Subsequent Feedlot Performance, Jack G. Riley, B. Cochran, Ronald V. Pope Jan 1987

Effects Of Rumensin® Ruminal Delivery Devices In Grazing Cattle On Subsequent Feedlot Performance, Jack G. Riley, B. Cochran, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Rumensin® Ruminal Delivery Devices put in place 76 days prior to steers entering a feedlot resulted in an average reduction in daily dry matter intake of 3.6% and a small 1.8% increase in daily gain during a controlled 28-day feeding phase. All steers were fed an 85% concentrate feedlot diet fortified with 30g/ton of Rumensin® and 10 g/ton of tylan®.


Raw Soybeans As A Protein Source For Growing Cattle, S. Anderson, Robert T. Brandt Jr. Jan 1987

Raw Soybeans As A Protein Source For Growing Cattle, S. Anderson, Robert T. Brandt Jr.

Kansas Agricultural Experiment Station Research Reports

A 60-day growth trial with 170 exotic crossbred steers (avg. wt. 626 lbs) was conducted to assess the value of raw soybeans in silage-based diets. Protein supplements were based on 1) urea, 2) urea plus soybean oil (SBO), 3) soybean meal (SBM), 4) SBM plus SBO, 5) rolled (RSB), and 6) whole (WSB) soybeans. Soybean oil was added to treatments 2 and 4 in amounts equivalent to that contributed from raw soybeans. Total diets were 11.5% crude protein. Steers fed SBM gained faster (P<.05) and consumed more feed than those fed RSB or WSB. However, SBO added back to the SBM diet resulted in performance similar to that of steers fed RSB or WSB (P=.47). This suggests that the protein value of SBM and raw soybeans was similar, but that small increments (less than 2% of diet dry matter) of soybean lipid inhibited ruminal diet digestion and(or} utilization. There was no advantage for rolling raw soybeans vs. feeding them whole (P=.45). Costs of gain were urea < raw soybeans < soybean meal.


Evaluating Serving Capacity Of Yearling Beef Bulls - A Field Trial, G. Boyd, L. Corah Jan 1987

Evaluating Serving Capacity Of Yearling Beef Bulls - A Field Trial, G. Boyd, L. Corah

Kansas Agricultural Experiment Station Research Reports

Results from two trials showed that serving capacity (SC) can be successfully evaluated in yearling beef bulls under field conditions and is influenced by sire line (P<.01). Also, providing sexual experience to low SC yearling bulls can improve SC and should be a standard part of the test. Scrotal circumference and breeding soundness examination scores, both traditional measures of bull fertility, were unrelated to SC.


Effects Of Pneumo-Guard H® And Vitamin E On Gain And Health Of Stockers Purchased As Steers And Bulls, F. Brazle Jan 1987

Effects Of Pneumo-Guard H® And Vitamin E On Gain And Health Of Stockers Purchased As Steers And Bulls, F. Brazle

Kansas Agricultural Experiment Station Research Reports

Pneumo-Guard H® and injectable Vitamin E did not improve cattle gain or reduce treatments required per animal during a 29-day receiving trial. Stockers purchased as steers gained faster (P<.001) and required fewer (P<.001) treatments per animal than bulls castrated on arrival.


Effect Of Bovatec® Level In Supplemental Feed On Performance And Forage Utilization Characteristics Of Wintering Beef Cattle, R.C. Cochran, L.R. Corah, K.A. Jacques, T.B. Avery, K.O. Zoellner, J.F. Higginbotham Jan 1987

Effect Of Bovatec® Level In Supplemental Feed On Performance And Forage Utilization Characteristics Of Wintering Beef Cattle, R.C. Cochran, L.R. Corah, K.A. Jacques, T.B. Avery, K.O. Zoellner, J.F. Higginbotham

Kansas Agricultural Experiment Station Research Reports

Various levels of lasalocid (Bovatec®) added to a protein supplement did not improve weight or condition change of beef cows grazing poor quality winter pasture. Similarly, calf birth weight and most forage utilization characteristics (e.g., intake, passage rate, and fermentation characteristics) were not altered by Bovatec level. Although forage digestibility was influenced by Bovatec level, changes were not sufficient to influence performance characteristics.


Effect Of Limited-Creep Feeding Calves Of Spring-Calving Cows Grazing Native Grass, F. Brazle, Gerry L. Kuhl, L. Corah, K. Zoellner Jan 1987

Effect Of Limited-Creep Feeding Calves Of Spring-Calving Cows Grazing Native Grass, F. Brazle, Gerry L. Kuhl, L. Corah, K. Zoellner

Kansas Agricultural Experiment Station Research Reports

Two limited-creep feeding trials were conducted with spring-born, suckling calves on native grass. The high-energy creep rations containing an ionophore were fed during the last 63 or 85 days before weaning in the two trials. Creep intake was limited with salt to about 1.5 lb per calf daily. Calves consuming the limited-creep feeds gained .26 to .31 lb more per head daily and required 4.4 to 5.5 lb of creep per lb of extra weaning weight.


Color Formation And Retention In Fresh Beef, Donald H. Kropf, Melvin C. Hunt, D. Piske Jan 1987

Color Formation And Retention In Fresh Beef, Donald H. Kropf, Melvin C. Hunt, D. Piske

Kansas Agricultural Experiment Station Research Reports

We conducted two studies in response to a severe problem with ground beef color encountered by beef fabricators and retailers. We concluded that: (1) Loss of muscle chemical-reducing capability upon grinding, with subsequent color deterioration, results from both the mechanical effect of grinding and incorporation of oxygen into the beef. (2) Flat, thin, surface muscles from beef carcasses retain more ability to bloom (turn bright red) if they are removed by hot boning or after a relatively short chill period.


Effect Of Commercial Inoculants On The Fermentation Of Alfalfa, Corn, Forage Sorghum, And Triticale Silages, K. Bolsen, H. Ilg, A. Laytimi, R. Hart, V. Chain, L. Nuzback, Daniel Y.C. Fung Jan 1987

Effect Of Commercial Inoculants On The Fermentation Of Alfalfa, Corn, Forage Sorghum, And Triticale Silages, K. Bolsen, H. Ilg, A. Laytimi, R. Hart, V. Chain, L. Nuzback, Daniel Y.C. Fung

Kansas Agricultural Experiment Station Research Reports

Fourteen commercial inoculants were evaluated in seven trials using alfalfa, corn, forage sorghum, and triticale silages. Microbial profiles of the inoculants and of the crops differed widely. Viable lactic acid bacteria (LAB) supplied per gram of fresh crop by the inoculants ranged from less than 103 to over 103. Only the alfalfas had 10 or fewer LAB per gram of crop when the forages were treated and as a result, fermentation responses were excellent for those inoculants that supplied 10 or more LAB per gram of treated crop. Corn and triticale underwent a very rapid fermentation rate with very little ...


Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully Jan 1987

Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully

Kansas Agricultural Experiment Station Research Reports

Several spaying and ovarian autografting methods were tested in three field trials with 658 grazing heifers. None of the techniques examined were found to have a beneficial effect on heifer gains compared to intact controls. Heifers' initial weight, frame size, and body condition score were associated with cattle performance; however, their relative impact on gains varied across the three trials.


Effect Of Stocker Receiving Diet On Subsequent Pasture Gains, F. Brazle, Gerry L. Kuhl, D. Harmon Jan 1987

Effect Of Stocker Receiving Diet On Subsequent Pasture Gains, F. Brazle, Gerry L. Kuhl, D. Harmon

Kansas Agricultural Experiment Station Research Reports

Seven diets were fed for 27 days to newly arrived heifers to evaluate their impact on stocker gains during the receiving and pasture periods. The diets were as follows: soybean hulls plus soybean meal; suncured alfalfa plus wheat middlings; dehydrated alfalfa plus grain sorghum; distillers dried grain plus cottonseed hulls; brome hay plus 2 lb protein supplement/day; prairie hay plus 2 lb protein supplement/day; and a commercial receiving ration. During the receiving period, diets of soybean hulls plus soybean meal, distillers dried grain plus cottonseed hulls, and the commercial receiving ration produced the highest cattle gains. The soybean ...


Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle, B. Kirch, S. Hamma, K. Bolsen, H. Ilg, J. Hoover Jan 1987

Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle, B. Kirch, S. Hamma, K. Bolsen, H. Ilg, J. Hoover

Kansas Agricultural Experiment Station Research Reports

Four trials were conducted to determine the feeding value of whole-plant forage and grain sorghum silages. In general, growing cattle fed grain sorghum hybrids (NK2778, Funk's 550, DeKalb 42Y, DeKalb E67) out performed those fed forage sorghum silages. Only moderate to high grain-content, forage sorghums (Buffalo Canex, Pioneer 947, Acco 351) gave performances that approached the grain sorghums. Low grain-content and nonheading forage sorghums (DeKalb 25E, Funk's G-1990) resulted in the poorest cattle performance. These studies indicate that grain content of a sorghum silage is the major determinant of cattle performance and that whole-plant grain sorghums should produce ...


Effect Of Environmental Temperature And An Inoculant On The Fermentation Of Forage Sorghum Silage, K. Bolsen Jan 1987

Effect Of Environmental Temperature And An Inoculant On The Fermentation Of Forage Sorghum Silage, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

The inoculants, BioPower®, increased the rate and efficiency of ensiling in Acco Paymaster 351 forage sorghum regardless of storage temperature. The untreated, 60 F silage fermentated slower and had higher pH, lower lactic acid, and higher acetic acid values than its 90 F counterpart.


Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope Jan 1987

Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Stocking rate in an intensive-early stocking system (1.25, 1.50, or 1.76 acres per steer) did not influence steer gains. Available forage on loamy upland sites was lower after steer removal on July 15 for the highest stocking rate. However, after late season rest, available forage was similar for all stocking rates. Steer gains were consistently greater for groups implanted with Compudose® (estradiol 78β or Compudose plus a Rumensin® (monensin) ruminal delivery device. The Rumensin device alone was successful in increasing average daily gain only at the highest stocking rate.


Effect Of Maturity At Harvest On Yield, Composition, And Feeding Value Of Forage And Grain Sorghum Silages, S. Hamma, B. Kirch, B. Downey, J. White, K. Bolsen Jan 1987

Effect Of Maturity At Harvest On Yield, Composition, And Feeding Value Of Forage And Grain Sorghum Silages, S. Hamma, B. Kirch, B. Downey, J. White, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

In the last 2 years, three trials were conducted to determine the influence of hybrid and stage of maturity at harvest on silage yield, composition, and nutritive value for 15 forage and nine grain sorghum hybrids. Agronomic data, such as days to half bloom, plant height, and whole-plant dry matter (OM) and grain yields, were also obtained. In Trial 1, Pioneer 947, Acco Paymaster 351, and DeKalb 25E forage sorghum hybrids had different whole-plant OM and crude protein (CP) contents. Whole-plant OM increased, whereas CP generally decreased with advancing maturity. Hybrid affected both DM intake and CP digestibility. Results indicated ...


Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem, E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques Jan 1987

Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem, E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques

Kansas Agricultural Experiment Station Research Reports

Supplementing beef steers consuming immature bluestem with 0, 1, 2, or 4 lbs of sorghum grain daily did not affect forage intake. Thus, total intake increased as level of grain increased. Total dry matter, cell wall, and starch digestibilities were mildly depressed with increasing grain. Rumen fill and rates of passage were similar for all treatments, and differences in rumen fermentation characteristics were minimal.


Implant Comparisons In Grazing And Finishing Spayed Heifers, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards Jan 1987

Implant Comparisons In Grazing And Finishing Spayed Heifers, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards

Kansas Agricultural Experiment Station Research Reports

Heifers that were flank-spayed plus rumen-ovarian autografted (FS+A) responded similarly to Ralgro®, Synovex-H®, and Synovex-S® implants on' pasture. Grazing heifers spayed by the Kimberling-Rupp technique also responded similarly to Synovex-H and Synovex-S implants. During the finishing phase, heifers implanted with Synovex-S gained 5.7% faster than heifers implanted with Ralgro, and those implanted with Synovex-H were intermediate in performance. There was no statistical interaction between spaying method and implant treatment during either the grazing or finishing phases.


Grazing And Feedlot Performance Of Heifers Spayed By Two Methods, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards Jan 1987

Grazing And Feedlot Performance Of Heifers Spayed By Two Methods, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards

Kansas Agricultural Experiment Station Research Reports

Two field trials were conducted to compare the pasture and finishing performance of heifers spayed by the Kimberling-Rupp(K-R) technique or by flank spaying plus autografting a piece of ovarian tissue into the rumen wall (FS+A). In trial 1, neither spaying method resulted in gains of grazing heifers different from that of intake controls; however, FS+A heifers gained 5.1% faster than K-R spayed heifers. In trial 2, grazing gains of heifers spayed by the two techniques were similar. During the finishing phase, no performance difference was found among intact, K-R, or FS+A heifers in trial 1 ...


Effect Of Terramycin® And Bovatec® In Free-Choice Mineral Mixtures On Gains Of Heifers Grazing Native Grass, F. Brazle, Gerry L. Kuhl, D. Harmon, S. Laudert Jan 1987

Effect Of Terramycin® And Bovatec® In Free-Choice Mineral Mixtures On Gains Of Heifers Grazing Native Grass, F. Brazle, Gerry L. Kuhl, D. Harmon, S. Laudert

Kansas Agricultural Experiment Station Research Reports

Supplementing heifers in an intensive-early grazing program with Terramycin ® or Bovatec ® in free-choice, mineral-soybean meal mixtures resulted in Comparable cattle performance. Both feed additive mixtures increased heifer gains about .3 lb per day compared to controls supplemented with a simple mineral mixture.


Efficacy Of Depo-Mga® In Feedlot Heifers, Jack G. Riley, Ronald V. Pope, L. O'Neill Jan 1987

Efficacy Of Depo-Mga® In Feedlot Heifers, Jack G. Riley, Ronald V. Pope, L. O'Neill

Kansas Agricultural Experiment Station Research Reports

Three levels of melengestrol acetate (30, 60, and 90 mg) injected subcutaneously as a liquid (DEPO-MGA ®) in the ear of heifers yielded high performance results comparable to feeding 0.5 mg of MGA per head daily. Heifers fed 0.5 mg MGA daily gained 6% faster and were 11% more efficient than heifers not receiving MGA. This study will be pooled with trials from 13 other locations in the U.S. to determine if further development and FDA clearance of DEPO-MGA ® will be pursued by the Upjohn Company.


Compudose® Vs Ralgro®/Synovex-S® Or Synovex-S®/Synovex-S® Reimplant Programs For Finishing Yearling Steers, S.B. Laudert, R.W. Lee Jan 1987

Compudose® Vs Ralgro®/Synovex-S® Or Synovex-S®/Synovex-S® Reimplant Programs For Finishing Yearling Steers, S.B. Laudert, R.W. Lee

Kansas Agricultural Experiment Station Research Reports

Three field trials were conducted with finishing yearling steers to compare the performance of cattle receiving Compudose® or Ralgro®/Synovex-S® and Synovex-S®/Synovex-S® reimplant combinations. No differences were found between Compudose and the reimplant programs in cattle daily gain, feed efficiency, or cost of gain. Compudose retention was 97.5% in the 1317 head implanted. Synovex-S implant site abscess rate ranged from 5.7 to 15.4%.


Comparative Feeding Value Of Grain Sorghum And Corn In Beef Cattle Diets, G. Goldy, K. Bolsen, Jack G. Riley Jan 1987

Comparative Feeding Value Of Grain Sorghum And Corn In Beef Cattle Diets, G. Goldy, K. Bolsen, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

Homozygous yellow endosperm grain sorghum had no advantage in feeding value over heterozygous yellow endosperm hybrids (P>.05). A heterozygous yellow endosperm hybrid, Funk's 550, had larger kernels (P<.001) and when dry rolled, produced more fine particles (P<.01). This may explain its trend toward improved feed efficiency, higher DM digestibility, and greater in vitro VFA production compared with the other dry processed grain sorghum hybrids tested. Our results do not support the traditional 12 to 16% price discount for grain sorghum relative to corn.


Effects Of Preweaning And Postweaning Implants On Suckling, Growing, And Finishing Steer Performance - A Three Trial Summary, D.D. Simms, T.B. Goehring, R.W. Lee, Robert T. Brandt Jr., S.B. Laudert, Gerry L. Kuhl Jan 1987

Effects Of Preweaning And Postweaning Implants On Suckling, Growing, And Finishing Steer Performance - A Three Trial Summary, D.D. Simms, T.B. Goehring, R.W. Lee, Robert T. Brandt Jr., S.B. Laudert, Gerry L. Kuhl

Kansas Agricultural Experiment Station Research Reports

Over 500 crossbred steers were used in three trials to compare lifetime implant strategies and to study the effects of implanting during the suckling period on performance in the growing and finishing periods. Contrary to previous research, implanting in the suckling period did not increase suckling gain. Implanting in the growing period increased (P<.05) average daily gain, and the implant response in the growing period was not influenced by suckling implant treatment. Steers implanted twice during the finishing period had similar finishing gains regardless of prior implant treatment. Steers implanted only once during the finishing phase gained less (P<.05) than those implanted twice, and while their gains were higher than those of control steers, the difference was small (P>.05). Implanting steers in the finishing phase tended to improve feed conversion but again the difference was not statistically significant. All implant treatments increased (P<.05) lifetime average daily gains and total gain, and there was no difference among implant combinations. Implant treatments increased lifetime gains by 30 to 54 lbs. Because implanting in the suckling period did not reduce cattle performance during the growing and finishing periods, there appears to be no basis for discounting the price of previously implanted cattle. Additionally, this study emphasizes the importance of reimplanting cattle during long finishing periods


Feeding Value Of Wheat And Sorghum Grain As Indicated By Absorbed Nutrients, K.L. Gross, D.L. Harmon, T.B. Avery Jan 1987

Feeding Value Of Wheat And Sorghum Grain As Indicated By Absorbed Nutrients, K.L. Gross, D.L. Harmon, T.B. Avery

Kansas Agricultural Experiment Station Research Reports

Steers fed diets based on dry-rolled wheat or sorghum grain alone or combined (50:50) showed no differences in net portal fluxes of glucose, L-lactate, ammonia, urea, or α-amino nitrogen. Portal blood flow was increased in steers fed the 50:50 diet. Total volatile fatty acid flux into the portal blood tended to be lower for steers fed the sorghum grain diet, which may partially explain the lower feeding value of sorghum grain compared to wheat or the two grains combined.


Influence Of Mixtures Of High Moisture Corn And Dry Rolled Wheat On Finishing Performance And Carcass Characteristics, B.J. Bock, Robert T. Brandt Jr., D.L. Harmon Jan 1987

Influence Of Mixtures Of High Moisture Corn And Dry Rolled Wheat On Finishing Performance And Carcass Characteristics, B.J. Bock, Robert T. Brandt Jr., D.L. Harmon

Kansas Agricultural Experiment Station Research Reports

Dry rolled wheat and high moisture corn were fed singly and in three combinations in a 132-day finishing trial. Daily gain, feed intake, and final live weight were greatest on the 75% corn:25% wheat diet. Feed efficiencies and carcass characteristics were not affected by grain combination. Daily gain and feed intake tended to decrease as percentage of wheat in the diet increased above 25%.
