Additive-Treated Corn Silage, Harvestore Cornlage, And Sodium Bicarbonate Supplement For Yearling Steers, S. Soderlund, K. Bolsen, H. Ilg, J. Hoover
Kansas Agricultural Experiment Station Research Reports
Steers fed Silo Guard II® treated corn silage gained 3.5% faster and were 8.3% more efficient than those fed the control silage. Cornlage (54% dry matter corn silage in an oxygen-limiting structure) produced numerically slower and less efficient gains than either treated or untreated silage, but differences in silages were not statistically significant. Steers fed sodium bicarbonate throughout the trial consumed 8.5% more silage, gained 14% faster (P<.05), and were 3% more efficient than those not fed bicarbonate; performance of steer fed bicarbonate for the first half of the trial was intermediate. Steers fed cornlage had a higher rumen fluid acetate:propionate ratio (P<.05) than those fed the control or Silo Guard II silages but there were no significant differences due to bicarbonate in rumen fluid volatile fatty acids. Silage DM recoveries and aerobic stabilities were similar for the control and Silo Guard II silages. Cornlage was less stable in air than the other two silages.
Effect Of Lasalocid Or Monensin On Feedlot (Grain) Bloat In Cattle, E.E. Bartley, Tiruvoor G. Nagaraja
Effect Of Lasalocid Or Monensin On Feedlot (Grain) Bloat In Cattle, E.E. Bartley, Tiruvoor G. Nagaraja
Kansas Agricultural Experiment Station Research Reports
Lasalocid or monensin (600 mg per 1000 lb body weight daily) was tested on cattle bloating on high grain diets. Bloat was reduced 92% by Lasalocid and 64% by monensin. When fed throughout the finishing period, lasalocid at 300 mg per 1000 lb body weight effectively prevented bloat from developing. However, 600 mg was required to control bloat in cattle that were already bloating.

Whole-Plant Forage, Grain Or Non-Heading Sorghum Silages, Cornlage, And Feed Flavor Supplements For Growing Calves, K. Bolsen, H. Ilg, M. Hinds, J. Hoover, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Four whole-plant silages produced in 1981 and 1982 were evaluated using 176 calves in two growing trials. Based on comparative rates and efficiencies of gain, feeding values were 115, 100, 78.5, and 62 for the cornlage, grain sorghum, forage sorghum, and non-heading sorghum silages, respectively. The poorer values for the forage and non-heading silages were due, in part, to low feed intakes. Rolling the grain and forage sorghum silages to break 85% to 95% of the kernels did not improve their value, and the good performance by calves suggests that the whole grain was well utilized.. A feed flavor supplement, …

Eight years of records for 1495 2-year old beef heifer calvings from two Kansas ranches were analyzed to determine the cause and effect"¢ of calving difficulty on subsequent reproductive performance and weaning weights of progeny. The study involved two herds of Simmental cattle (spring and fall calving) and one herd of fall calving Angus cattle. Heifers were classified as either requiring or not requiring assistance with their first calf. Herds were analyzed separately. Percentages of heifers requiring assistance for the Angus, spring calving Simmental and fall calving Simmental herds were 36%, 57% and 38%, respectively. In all herds, calves from …
High-Moisture Or Dry Corn, Roughage Sources, And Protein Supplements For Short-Fed Finishing Steers, B. Young, H. Ilg, K. Bolsen
High-Moisture Or Dry Corn, Roughage Sources, And Protein Supplements For Short-Fed Finishing Steers, B. Young, H. Ilg, K. Bolsen
Kansas Agricultural Experiment Station Research Reports
Dry corn, stave ensiled high-moisture corn (HMC), stave ensiled HMC treated with urea, and Harvestore ensiled HMC were evaluated in a steer finishing trial. Alfalfa hay and corn silage were the roughages and soybean meal or urea, the nitrogen sources. There were no differences in steer performance for corn treatments, but steer performance was significantly improved when alfalfa hay rather than corn silage was the roughage. Urea supplements significantly depressed steer performance compared with soybean meal additions; a combination of urea and soybean meal gave intermediate performance.

Elpwa And Molasses Additives For High Moisture Sorghum Grain, J. Heidker, H. Ilg, K. Bolsen, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
ELPWA (a lactobacillus inoculant with antioxidant), molasses, or both combined were evaluated as additives to high moisture sorghum grain ensiled in concrete stave silos. ELPWA treated grain had the greatest temperature increase during ensiling. Final lactobacillus counts were higher in the ELPWA + molasses treated grain, however, the initial rate of increase was greatest in ELPWA or molasses treated grains. Control and molasses treated grains had the fastest decline in pH and the lowest final pH. Aerobic stability of the ensiled grain depended on the strata of the silo sampled and the temperature to which the grain was exposed but …

Stocking Rate, Supplementation And Implants For Steers Grazing Bluestem Pasture In Early Summer, R. Held, E.F. Smith, Jack G. Riley, Clenton E. Owensby
Kansas Agricultural Experiment Station Research Reports
Native bluestem pastures were grazed from May 10 to July 15, 1982 by steers averaging 599 lbs, at stocking rates 1.82, 1.5, 1.2 acres per steer. Daily gains were similar for all rates, but gain per acre increased with increased stocking rate. Half of the steers were self-fed a salt-limiting sorghum grain-Rumensin® mixture, at about 1.8lb per steer per day. Supplementation increased daily gain (P<.05) but actual differences were small (2.08 vs. 1.91 lb per day). Gain per acre was increased 7 lbs by supplementation. Herbage yields at mid-July were least on the heavily stocked pastures, but by October regrowth on all pasture was equal. Stocking rate did not affect botanical composition. There were no significant gain differences for steers implanted with either Compudose®, Ralgro® or Synovex®, even though 24 percent of the Compudose implants were lost by mid-summer.

Kansas Agricultural Experiment Station Research Reports
Data were collected on 85,195 cattle sold in 15 Kansas auctions during October and November 1981. Buyers discounted sick cattle heavily, 'and discounts were heavier on sick calves than yearlings. The discount for bulls vs. steers increased as weight increased, but the discount for heifers vs. steers decreased with increasing weight. Buyers pay little if any premium for thin cattle, but severely discount very thin or fat cattle. Cattle with average fill sold as well or better than shrunk cattle. Gaunt or tanked cattle were heavily discounted. Best prices were paid for lots of 20 to 40 head, with heavy …

Survey Of Kansas Cow-Calf Producers, Jack G. Riley
Kansas Agricultural Experiment Station Research Reports
Results of a 1982 survey were compared to a similar survey conducted 5 years earlier to determine if the acceptance of management practices had changed during that time period. The cow herd size was similar in both surveys but there was a 6% increase in crossbred cows and a substantial change in sire breed. The breeding season had been shortened to 110 days but was still too long. There was no apparent change in acceptance of semen testing or pregnancy check but 23% more producers were using a worming program. Fly control ear tags were not available in 1977-78 but …

Management Options For Pregnant Feedlot Heifers, M. Simon, L.E. Keay, G. Kiracofe, Jack G. Riley
Kansas Agricultural Experiment Station Research Reports
Heifers that were 167 days pregnant when slaughtered gained faster and more efficiently than open heifers, or heifers that had been aborted with a prostaglandin analog at 83 or 138 days, unless the slaughter weight was adjusted for the 1.7% lower carcass yield (dressing %). When the slaughter weights for all these management options were adjusted using the carcass yield of open heifers, there was no difference in gain except for the depressed performance associated with late abortions. However, open heifers were 6.7% more efficient than heifers pregnant when slaughtered. Heifers aborted at 138 days had substantially reduced gains and …

Two trials were conducted to evaluate the effectiveness of revaccinating recently processed cattle with modified live IBR and BVD vaccine. Revaccination decreased total illness 24 to 26%. A significant reduction in clinically sick calves occurred by 48 hours after revaccination and continued for the reminder of the observation period.
Comparative Intake Of Bone Meal And Calcium Phosphate Mineral Mixtures As Phosphorus Sources For Grazing Steers And Lactating Cows, F. Brazle, Gerry L. Kuhl, T. Wary, Dale L. Lanham
Comparative Intake Of Bone Meal And Calcium Phosphate Mineral Mixtures As Phosphorus Sources For Grazing Steers And Lactating Cows, F. Brazle, Gerry L. Kuhl, T. Wary, Dale L. Lanham
Kansas Agricultural Experiment Station Research Reports
Steers on native grass consumed equal amounts of mixtures containing 50% trace mineralized salt and either 50% bone meal or 50% calcium phosphate. Lactating cows consumed about 60% more of the bone meal:salt mixture. This research verifies that both products are palatable supplemental phosphorus sources and that choice of product should be a function of cost per unit of phosphorus.
