Relationship of cow weight, cow condition and dosage of prostaglandin on synchronized heat
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Simms, D.; Corah, L.
Simmental cows on two Kansas ranches received either 2 or 3 ml injections of prostaglandin cloprostenol (Estrumate). Dose levels had little effect on response rate in either small or large cows. However, for each unit increase in body condition score, 12% more cows expressed heat.

Effect of Bovatec,Oxytetracycline (OTC), Bovalec Plus OTC and Rumensin-Tylan combination on feedlot performance and liver abscess control in finishing steers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Lee, B.; Laudert, S.
Adding Bovatec, OTC, Bovalec plus OTC or Rumensin-Tylan to finishing steer diets did not significantly improve average daily gain in the 133 day feeding period, but did improve (P<.05) feed to gain ratios. The Rumensin-Tylan combination was the only treatment that reduced (P<.05) liver abscess incidences.

Effect of Actaplanin on performance of grazing steers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Lomas, Lyle W.; llomas
Feeding actaplanin in a loose mineral mix or twice weekly in a supplement significantly improve gains of grazing steers. The greatest improvement in performance was found with average daily actaplanin intakes of 255 or 257 mg per head in the two trials.

Effect of Lasalocid on the sexual development of beef heifers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Corah, L.; Riley, Jack G.
Lasalocid (Bovatec®) improved daily gain of replacement heifers by .20 lb per day and reduced the time to first heat in heifers fed on a lower level of energy, but had no significant affect in the higher energy group. Feeding Lasalocid did not affect conception rates.

Comparison of Compudose®, Ralgro® and Synovex-C® for suckling steer calves
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Simms, D.D.; Schalles, R.
The comparative growth-promoting value of Compudose, Ralgro, Ralgro + Ralgro reimplant, and Synovex-C + Synovex-C reimplant was evaluated on five Kansas ranches with 674 suckling steer calves in seven trials conducted during 1982 and 1983. The Ralgro + Ralgro reimplant program increased gain significantly (P<.05) over controls, with an average improvement of 3.9%. Either a single Ralgro or Compudose implant at branding increased gain about 2.6%. Implanting with Synovex-C produced 1% improvement in gain.

Effect of a single Ralgro implant on conception rates and calving difficulty in first calf beef heifers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Bolze, R.P.; Corah, L.R.; Pruitt, R.J.
Three hundred and seventy four heifers from two Kansas ranches were used to determine if a single Ralgro implant given either at two months of age or at weaning would influence pelvic development and subsequent calving difficulty or conception rates. The study involved two hers of Simmental (spring and fall calving) and one herd of fall calving Angus cattle. Ralgro did not influence conception rates as yearlings, or percentages of heifers requiring assistance with their first calf. Implanted heifers had larger pelvic areas as yearlings, but the advantage disappeared by two years of age. Pelvic area in assisted vs unassisted two year old heifers did not differ.

Toxicity problems with ammoniated dry roughages
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Simms, D.; Kuhl, Gerry L.; Brethour, J.
In two trials conducted at the Fort Hays Experiment Station, symptoms of toxicity (hyperexcitability, circling, convulsions, death) were observed in several newborn calves (l to 14 days of age) nursing cows consuming ammoniated forage sorghum hay. None of these symptoms was observed in calves nursing cows consuming untreated hay. No toxicity symptoms were observed in the cows on any treatment. However, several instances of similar symptoms in cattle consuming ammoniated forages have been reported in growing calves and adult cattle in Kansas, Texas, California, and Kentucky. The primary forages involved in these incidents were forage sorghum, hybrid sudan, cereal grain, brome, and fescue hays. To date, no problems have been reported with ammoniated wheat straw or other Poor quality forages. Analyses of the treated forages associated with several of these toxicity incidents have shown relatively high levels of imidazole compounds-chemicals with convulsive properties previously implicated in toxicity with ammoniated molasses.

Implant comparisons for finishing steers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Laudert, S.; Kuhl, Gerry L.; Walker, M.
A one hundred and forty day field trial was conducted to evaluate the relative performance of steers implanted with Compudose, Ralgro and Synovex-S. Daily gains of cattle receiving a single initial implant were increased 8.0% with Compudose, 12.7% with Ralgro and 21.5% with Synovex-S compared to non-implanted controls. Steers on a reimplant program with Ralgro and/or Synovex-S gained 23.6 to 24.9% faster than controls, with no significant difference due to implant brand or sequence.

Effect of ammonia level and treatment temperature on intake and digestibility of wheat straw by lambs
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Laytimi, A.; Bolsen, K.; Janicki, B.
Replicate, covered wheat straw (WS) stacks were treated with 1.5 or 3.0% anhydrous ammonia in three environmental chambers at 37, 68, or 95 F, for 23 days. Then digestibility was measured (wethers). Rations were 88% wheat straw and 12% supplement. The control wheat straw was non-ammoniated but contained 5% urea in the supplement. Stack temperatures increased rapidly within 2.5 hours post-ammoniation, and equilibrated at chamber temperatures for the rest of the treatment period. Both crude protein (CP) and in vitro matter digestibility of the WS increased with ammonia level and treatment temperature. Percent of the ammonia recovered increased with temperature and was always higher with the low ammonia level treatment. Ammoniation improved ration intakes and dry matter digestibility, but did not increase CP digestibility which decreased as temperature increased. Ammoniation solubilized the hemicelluloses, cellulose, and lignin and increased the digestibility of the fiber components.

Comparison of Compudose with Ralgro or Synovex-S reimplant programs for finishing steers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Laudert, S.B.; Davis, G.V. Jr.
Finishing yearling steers reimplanted with Synovex-S or Ralgro gained 6.8 and 4.2% faster, respectively, than those implanted with Compudose. However, feed efficiency was not significantly different among treatments. Steers implanted with Compudose gained 5.1% faster and more efficiently than those implanted with a single Ralgro.

Sodium bicarbonate and feed flavor supplements for calves fed forage sorghum silage
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Bolsen, K.; Axe, D.
High-moisture forage sorghum silage was fed to 108 steer calves to measure the effect of sodium bicarbonate and feed flavor (Omniflavor®) on calf performance. Overall performance was similar for all three rations by the end of the 94-day trial, but at days 29 to 56, when weather conditions were extremely cold, bicarbonate and Omniflavor each gave improved rate and efficiency of gains.

Single vs. reimplant programs for finishing steers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Riley, Jack G.; Pope, Ronald V.; rvpope
Finishing yearling beef steers were used to compare various implant programs in a 167-day trial. All implant programs increased daily gain ranging from 6.6 to 25.4% over non-implanted controls and improved feed efficiency ranging from .5 to 13.9%. Steers implanted with Ralgro® initially and reimplanted 75 days later with Synovex-S gained the fastest and most

The weather in 1982 and 1983
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Dean Bark, L.
The 1983 weather in Kansas upset carefully laid plans and confounded the best management techniques. Yet the averages for 1982 and 1983 appear very similar. In Manhattan, the average temperatures were 54.04 F for 1982 and 54.06 for 1983. Precipitation totals were 32.88 in. for 1982 and 35.74 in. for 1983. However, those who watched their crops dry up in the summer of 1983 after delayed planting because of wet fields, and suffered with their livestock through heat stress in July and August and cold stress during December know differently. Neither our crops nor our livestock ever experience “average” weather. They experience the extremes of weather, and growth and gain are at the mercy of the variability. We can get a better picture of the last two years’ weather by looking at the actual daily values and comparing them to the normal-or average-for that time of the year.

CULBAC® and ADD-F® (formic acid) additives for sudangrass and high moisture shelled corn silages
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Bolsen, K.; Hinds, M.; Ilg, H.
Laboratory silos were used in three trials to evaluate sudangrass (slightly or moderately wilted) and high moisture corn silages, each receiving the following treatments: (1) control (no additive); (2) CULBAC® dry; (3) CULBAC® liquid; and (4) ADD-F® (formic acid). Although the 12 silages were well preserved visually, there were differences in their chemical compositions. Silages treated with CULBAC dry had the highest DM recoveries and probably the most efficient fermentations. As expected, formic acid restricted the amount of fermentation, but surprisingly, it did not improve DM recovery.

Silage additive update: 1984
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Bolsen, K.; Hinds, M.; Brethour, J.
Numerous commercial silage additives, whose manufacturers claim will improve silage quality, are available to Kansas farmers and ranchers. We believe that these claims must ultimately be documented with farm-scale research. To date, Manhattan and Ft. Hays farm-scale silo results clearly indicate that a few silage additives do improve silage quality and are cost-effective. Several of them have consistently reduced “in silo” losses. But results probably will not be favorable with all additives under every farm condition. Nor will research results obtained with one commercial product in our trials also apply to other products on the market, however similar in ingredient formulation.

High moisture corn ensiled with urea for cattle finishing rations
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Young, B.; Smith, R.; Bolsen, K.; Ilg, H.
Dry rolled corn, ensiled high moisture corn, and high moisture corn that was rolled and ensiled with urea or left whole and ensiled with urea were compared in two cattle trials. Dry corn gave the poorest cattle performance; rolled, ensiled high moisture corn gave the best. When corn was left whole, adding urea prior to ensiling increased dry matter losses in the silo and produced a butyric acid fermentation. Urea increased the bunk life of the ensiled high moisture corn.

Effects of rapid and delay silo filling and 1177® silage inoculant on performance of growing cattle fed corn and sorghum silages.
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Bolsen, K.; Ilg, H.; Hinds, M.; Milliken, George A.; Hoover, J.
Eight concrete stave silos (10 x 50 ft) were used in two trials to evaluate rapid (24 to 36 hr) and delay (15 days) filling, each with our without 1177® silage inoculant. Corn silage was used in Trial 1; forage sorghum in Trial 2. The delay-fill silages had a dry matter (DM) range of 34.4 to 39.9% in Trial 1 and 24.2 to 29.6% in Trial 1. All eight silages were well preserved with the four delay-fill silos having lower total fermentation acids than their rapid-fill counterparts. With corn silage, the rapid-fill silos had higher silage DM recoveries than the delay-fill silos. 1177® improved DM recovery in the rapid-fill silo but not in the delay-fill silo. With forage sorghum silage, the rapid-fill silos lost effluent which contributed to lower DM recoveries than in the delay-fill silos. 1177® improved DM recoveries with both fill procedures for the wetter sorghums. Steer performance was similar (P>.05) for all four treatments within each silage. When silage recovery and steer performance were combined, the 1177® treated silages produced more pounds of beef than their respective controls. When corn and forage sorghum silages were averaged, 1177® produced 3.3 lb more beef gain per ton of crop ensiled than uninoculated controls.

Comparison of Synovex-S and STEER-oid implants for feedlot steers
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Lee, B.; Laudert, S.
Synovex-S and STEER-oid were compared in a 133-day finishing trial to evaluate their effects on growth and carcass traits of yearling steers. No significant differences in average daily gain, feed intake, feed to gain ratio, carcass weight, ribeye area, fat thickness, quality grade or yield grade were detected between the two implants at the end of the trial. However, significant differences in feed efficiency were detected during days 0-35 and 36-63, possibly due to different release rates of the implants.

Feedlot performance of Angus and Brahman x Angus steers during cold weather
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Boyles, S.; Riley, Jack G.; Pope, Ronald V.; rvpope
Straightbred Angus steers gained .21 lb/day faster than Brahman x Angus steers during a 184-day winter feeding trial. Angus steers had a higher yield grade. more fat thickness at 12th rib, and graded 90% Choice. Brahman x Angus steers were 40 days younger at slaughter, had more carcass weight/day of age and larger loin eyes, but only graded 10% choice. There was no difference in feed efficiency.

Effect of sorghum type and harvest date on silage feeding value
(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14) Smith, R.; Bolsen, K.; Ilg, H.; Hinds, M.; Dickerson, J.; Hoover, J.; Pope, Ronald V.; rvpope
Five silages produced in 1982 were evaluated in two growing trials using 96 steer calves. Forage sorghum silage (heading) was assigned a feeding value of 100. Based on comparative rates and efficiencies of gain, feeding value for the grain sorghum silage averaged 107.5 in Trial 1. The non-heading forage sorghum silage had a value of 64.6 in Trial 1 but only 40.2 before freezing and 31.4 after freezing in Trial 2. The poor values for the non-heading silages were due, in part, to very low feed intakes. There was no advantage in harvesting the non-heading sorghum after a freeze. Rolling the grain sorghum silage to break 95 % of the grain did not improve its value. In Trial 2, adding alfalfa haylage to the non-heading silages did increase steer performance.
