A Comparison Of Selected Breed Crosses On Growth Rate During Long-Term Grazing (1986), Jack G. Riley, Ronald V. Pope
A Comparison Of Selected Breed Crosses On Growth Rate During Long-Term Grazing (1986), Jack G. Riley, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Brahman crossbred and Simmental crossbred calves gained similarly during a 312-day, native range grazing study. Longhorn crossbreds gained less than the Brahman or Simmental crosses but more than the British crossbreds, which served as controls. Most of the gain advantage was obtained during the summer portion (April 30-September 20) of the project.
A Comparison Of Synovex-S® And Steer-Oid® Implants For Finishing Cattle (1986), G. Goldy, Jack G. Riley, Ronald V. Pope
A Comparison Of Synovex-S® And Steer-Oid® Implants For Finishing Cattle (1986), G. Goldy, Jack G. Riley, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
There were no significant differences in performance or carcass traits for finishing cattle implanted with either Synovex-S® or STEER-oid®. The 122-day trial used 180 steers, with each treatment having 15 replicates.

Fusobacterium necrophorum was the predominant bacterial isolate from 49 liver abscesses. Biotype A tended to occur in pure infections and produced a more severe tissue reaction than biotype B, which tended to occur as a mixed infection.
Adding Fat And/Or Sodium Bicarbonate To Steer Finishing Rations That Contain Wheat (1986), J.R. Brethour, B. Lee, Jack G. Riley
Adding Fat And/Or Sodium Bicarbonate To Steer Finishing Rations That Contain Wheat (1986), J.R. Brethour, B. Lee, Jack G. Riley
Kansas Agricultural Experiment Station Research Reports
Adding .6 pound fat or .22 pound sodium bicarbonate (soda) to finishing rations containing rolled wheat significantly improved performance and appeared to increase the substitution value of wheat. Both fat and soda increased feed intake. The improved gains from adding fat corresponded to increased energy intake. However, soda seemed to enhance nutrient utilization. There was more response to fat when we fed 100 percent vs. 50 percent wheat, but feeding 100 percent wheat depressed performance, with or without fat, to unsatisfactory levels.
Influence Of Ionophore Addition To High-Grain Diets On Net Nutrient Absorption (1986), D.L. Harmon, T.B. Avery
Influence Of Ionophore Addition To High-Grain Diets On Net Nutrient Absorption (1986), D.L. Harmon, T.B. Avery
Kansas Agricultural Experiment Station Research Reports
Adding ionophores to a high grain diet increased glucose absorption and decreased the transport of urea back into the gut. These changes are consistent with the antibiotic effects of these compounds. Decreased microbial activity in the gut and shifts in the pattern of absorbed nutrients may help explain the improvements in feed efficiency seen with ionophore addition.
Additive-Treated Corn Silage For Growing Cattle (1986), K. Bolsen, R. Smith, H. Ilg, D. Axe
Additive-Treated Corn Silage For Growing Cattle (1986), K. Bolsen, R. Smith, H. Ilg, D. Axe
Kansas Agricultural Experiment Station Research Reports
The response of corn silage to the additive, Silo-Best Soluble®, was not consistent for the farm silo criteria measured. Ensiling temperatures and chemical compositions were similar for control and treated silages, except for ethanol, which was lower in the treated silage. Dry matter recovery favored the treated silage in both the top and bottom halves of the silos and in buried bags. Although daily gains were similar for calves fed control and treated silages, feed conversion was slightly better for those fed control silage.
Effect Of Rotational Grazing By Yearlings On Early-Intensive, Double-Stocked, Native Grass (1986), F. Brazle, Gerry L. Kuhl
Effect Of Rotational Grazing By Yearlings On Early-Intensive, Double-Stocked, Native Grass (1986), F. Brazle, Gerry L. Kuhl
Kansas Agricultural Experiment Station Research Reports
Continuous, early-intensive (double-stocked) grazing vs. early-intensive grazing using a two-pasture, 16 to 18-day rotation were compared in three experiments. No significant differences were found (P>.15) in daily gains of stockers or forage remaining after the 2 ½ month grazing season
Effects Of Compudose® Implants From Birth To Slaughter On Carcass And Meat Traits Of Young Bulls And Steers (1986), T.D. Hopkins, Michael E. Dikeman
Effects Of Compudose® Implants From Birth To Slaughter On Carcass And Meat Traits Of Young Bulls And Steers (1986), T.D. Hopkins, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Implanting young bulls with Compudose® three times from birth to slaughter resulted in performance similar to that of nonimplanted bulls, but decreased masculinity development. Implanted bulls tended to have higher marbling scores, more tender meat, more youthful carcasses, and lighter lean color than nonimplanted bulls. Although both implanted and nonimplanted bulls were more efficient and gained faster in the feedlot than implanted steers, the steers showed very little carcass masculinity and had finer-textured lean. Implanted steers had more youthful carcasses and lower Warner-Bratzler shear values than nonimplanted bulls. However, nonimplanted bulls grew faster, were more efficient, had larger ribeyes and …
Aborting Feedlot Heifers With Alfavet® Or Bovilene® (1986), S. Laudert, G. Boyd, Gerry L. Kuhl
Aborting Feedlot Heifers With Alfavet® Or Bovilene® (1986), S. Laudert, G. Boyd, Gerry L. Kuhl
Kansas Agricultural Experiment Station Research Reports
Alfavet® (alfaprostol), an experimental prostaglandin analog for inducing abortion in feedlot heifers, was evaluated for efficacy. Abortion was induced within 8 days following injection of 5 mg alfaprostol in 45 of 51 heifers (88.2%) ranging from 40 to 150 days in gestation. Bovilene® (fenprostalene), injected at 1 mg per head resulted in abortion in 45 of 49 heifers (91.8%) of similar pregnancy status. Both products were 95-100% effective from 40 to 120 days of pregnancy, but only 75% effective from 121 to 150 days.
The Effect Of Gnrh On Pregnancy Rates In Estrus-Synchronized Beef Heifers (1986), M. Ferguson, L. Corah
The Effect Of Gnrh On Pregnancy Rates In Estrus-Synchronized Beef Heifers (1986), M. Ferguson, L. Corah
Kansas Agricultural Experiment Station Research Reports
Injecting 100 mcg of GnRH into cycling heifers at artificial insemination following estrus synchronization with either prostaglandin or Syncro-Mate-B® did not improve first service conception rate. However, GnRH improved first service conception in Syncro-Mate-B®-treated heifers that did not exhibit estrus prior to breeding and were bred by appointment.
Evaluation Of Rumensin® In Late Season, Salt-Limited, Protein Supplements Fed To Grazing Steers And Heifers (1986), L.R. Corah, F.K. Brazle
Evaluation Of Rumensin® In Late Season, Salt-Limited, Protein Supplements Fed To Grazing Steers And Heifers (1986), L.R. Corah, F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
Even though an average daily Rumensin® consumption of over 100 mg per was achieved in all three trials, it did not significantly improve daily gains of steers or heifers grazing late-season native range. Late-season protein supplementation improved average daily gain by over .2 lb per head.
Effect Of Moisture, Bale Type, And A Preservative On Alfalfa Hay Quality And Feeding Value (1986), A. Laytimi, J. Arledge, C. Grimes, K. Bolsen
Effect Of Moisture, Bale Type, And A Preservative On Alfalfa Hay Quality And Feeding Value (1986), A. Laytimi, J. Arledge, C. Grimes, K. Bolsen
Kansas Agricultural Experiment Station Research Reports
In the first of two alfalfa hay experiments, lambs fed small bale hays averaged 16% better gains and feed conversions than those fed large bale hays; Fresh Cut®-treated hay gave 9% better performance than untreated hays; and medium-moisture hays produced 12% faster and more efficient gains than low-moisture hays. In the second experiment, hay baled above 30% moisture had excessive heating, more discoloration and mold growth, higher storage losses, and lower dry matter and protein digestibilities compared with 15% moisture hay.
Effect Of Sodium Bicarbonate And Sodium Bentonite On Digestion And Ruminal Fermentation Of Forage Sorghum Silage-Based Rations Fed To Growing Steers (1986), K. Jacques, D. Axe, T. Harris, D. Harmon, K. Bolsen
Effect Of Sodium Bicarbonate And Sodium Bentonite On Digestion And Ruminal Fermentation Of Forage Sorghum Silage-Based Rations Fed To Growing Steers (1986), K. Jacques, D. Axe, T. Harris, D. Harmon, K. Bolsen
Kansas Agricultural Experiment Station Research Reports
One percent sodium bicarbonate increased intake of a 50% silage-50% grain ration, but had no effect on intake of an 84% sorghum silage ration. Adding concentrate (rolled sorghum grain) lowered rumen pH slightly and decreased acid detergent fiber and starch digestion. The bicarbonate had no effect on digestibility, but 2% bentonite lowered digestibility of neutral and acid detergent fiber. Neither compound affected ruminal fermentation characteristics.
Effect Of Maturity At Harvest On Yield And Composition Of Hybrid Grain And Forage Sorghum Silages (1986), R. Smith, K. Bolsen, T. Walter, B. Kirch
Effect Of Maturity At Harvest On Yield And Composition Of Hybrid Grain And Forage Sorghum Silages (1986), R. Smith, K. Bolsen, T. Walter, B. Kirch
Kansas Agricultural Experiment Station Research Reports
Results from two trials indicate that grain sorghums can produce high, whole-crop dry matter yields in a short time. Although grain sorghum whole-crop silage may yield less tonnage than forage sorghum, its higher crude protein and grain-to-forage ratio could more than compensate for the difference. Maximum yields, both whole-crop and grain, were obtained at late-dough maturity in both years. However, since high quality silages were made at each harvest stage, grain sorghums had a relatively long harvest season. Grain sorghums had a dry matter content suitable for ensiling over the range of maturities studied. In addition, their yield and nutrient …

Experimental Implant Evaluated In Grazing Yearling Steers (1986), S. Laudert, C. Sauerwein
Kansas Agricultural Experiment Station Research Reports
An experimental implant containing Beta-estradiol increased (P<.05) daily gain of grazing yearling steers by 15.5% compared to controls. Compudose implants increased (P<.01) daily gain by 13.5%. There was no gain difference between the experimental implant and Compudose.
Effects Of Monensin And Sodium Propionate On Net Nutrient Absorption In Steers Fed High-Grain Diets (1986), D.L. Harmon, T.B. Avery
Effects Of Monensin And Sodium Propionate On Net Nutrient Absorption In Steers Fed High-Grain Diets (1986), D.L. Harmon, T.B. Avery
Kansas Agricultural Experiment Station Research Reports
Adding either monensin or sodium propionate alone or in combination to the diet of steers fed high-grain diets resulted in increased net absorption of glucose. Monensin reduced ammonia output and gut uptake of urea. We propose that increased propionate availability reduces the utilization of glucose by gut tissues. allowing more glucose to reach the portal system. These changes may contribute to the increased feed efficiency seen when monensin is fed.
