Effects Of Grazing System And Use Of A Pasture-Phase Implant On Grazing And Finishing Performance Of Steers, Robert T. Brandt Jr., C.T. Milton, Clenton E. Owensby Jan 1995

Effects Of Grazing System And Use Of A Pasture-Phase Implant On Grazing And Finishing Performance Of Steers, Robert T. Brandt Jr., C.T. Milton, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Results are presented from the first year of a 2-year study to evaluate the effects of grazing system (intensive-early stocking or IES vs season-long grazing or SLG) with or without a pasture-phase implant (Synovex-S®) on grazing and subsequent finishing performance. Compared to a SLG system, IES resulted in faster rate of gain on pasture and more beef produced per acre, although SLG resulted in greater total pasture gain per animal. Implanting improved rate of gain and increased beef per acre, particularly for IES steers. In the feedlot, IES steers gained weight faster and more efficiently than SLG steers. However, SLG ...

Effect Of Bacterial Inoculants On The Preservation And Nutritive Value Of Whole-Plant Corn Silages, K.K. Bolsen, D.W. Rice, M.A. Hinds, C. Zimmermann, Matthew A. Young

Kansas Agricultural Experiment Station Research Reports

Inoculated and control corn silages were compare d using pilot-scale silos. Inoculated silages (Pioneer inoculant 117 4 and 1132) had significantly higher lactic to acetic acid ratios, and numerically lower values for DM loss, acetic acid, ethanol, and ammonia-nitrogen than the control silage"”evidence that both inoculants produced a more efficient fermentation . Although the inoculated silage rations had higher DM intakes than the control, nutrient digestibilities were similar for the three silages . These results are consistent with numerous studies that compared untreated and inoculant-treated silages over a wide range of crops and ensiling conditions in our research during the past ...

Influence Of Degradable Intake Protein On Site And Extent Of Digestion In Beef Cows Consuming Low-Quality, Tallgrass-Prairie Forage, H.H. Köster, R.C. Cochran, E.S. Vanzant, G. St Jean, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Five Angus x Hereford cow s with ruminal and duodenal fistulas were used to evaluate the effect of providing increasing degradable intake protein (DIP) o n the site and extent of digestion of dormant, tallgrass-prairie forage. The DIP was provided from sodium caseinate, divided in two equal portions and infused intraruminally twice daily. Levels of DIP were: 0, 180, 360, 540, and 720 g/day. Supplemental DIP generally improved utilization of low quality forage, with maximum effects on duodenal N flow and forage organic matter intake at 540 g DIP/day.

How The Price Of Different Breeds Of Feeder Cattle Has Changed Over Time, F.K. Brazle, J.R. Mintert, J. Iii Sartwelle, R.P. Jr. Bolze, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Data on feeder steer characteristics, breeds, and prices were collected in 1986/87 and 1993 at Kansas and Missouri feeder cattle auctions to identify changes in buyers' preferences for various breeds. Results from models of feeder steer price/characteristics indicate that the relative value of many breeds changed over time. Relative to Hereford steers, Angus, Hereford x Angus cross, Continental cross, and low percentage Brahman steers all gained in price from 1986/87 to 1993. Longhorn Cross steers' price declined relative to Hereford steers over the same time period.

Kansas Agricultural Experiment Station Research Reports

The 1994 growing season was characterized by near norm al rainfall and temperatures. Both whole-plant DM and grain yields were excellent for all hybrid s. The middle-season Pioneer 947 hybrid had the highest grain yield. The two dual-purpose hybrids had the highest whole-plant DM yields, and the male sterile (Golden Harvest H-1) and the grain sorghum (DeKalb 42Y) had the lowest. Strong winds in the first week in September caused substantial lodging in three of the four tall middle- and late-season hybrids (DeKalb FS-5 and Golden Harvest H-2 and H-68). Two of the short height, dual purpose hybrids (Northrup King ...

Kansas Agricultural Experiment Station Research Reports

One hundred twenty medium-framed steers were fed one of six high (90%) concentrate rations: control (0), 5, 10, or 15% pelleted wheat middlings (WM) replacing the concentrate (dry rolled corn) and 5 or 10% pelleted WM replacing the roughage (chopped alfalfa hay). Increasing WM replacement of the concentrate increased both dry matter (DM) intake and feed/gain ratio linearly, without influencing daily gain or final weight. WM replacement of the roughage decreased DM intake linearly, but it ha d no effect on daily gain, final weight, or feed efficiency . The data indicate that WM could replace only 5% of the ...


Optimal Urea Level In Corn-Based Finishing Diets Containing Alfalfa As The Roughage Source, C.T. Milton, Robert T. Brandt Jr. Jan 1995

Optimal Urea Level In Corn-Based Finishing Diets Containing Alfalfa As The Roughage Source, C.T. Milton, Robert T. Brandt Jr.

Kansas Agricultural Experiment Station Research Reports

One hundred medium-growth potential, crossbred yearling steers (766 lb) were used to identify the optimal level of urea in finishing diets, based on growth and carcass traits. The corn-base d diets had no urea o r contained .35, .70, 1.05, or 1.40% urea (dry matter basis) and no other supplemental protein. Alfalfa hay (10% of DM) was the roughage source and contained 16% crude protein. Feed efficiency and gain were improved by .35% urea, with little improvement from higher additions. Regression analysis indicated that the optimal level of urea for gain and feed efficiency was .5% of dietary ...


Combinations Of Nonprotein Nitrogen And Natural Protein Affect Performance Of Finishing Steers Fed Flaked Corn Diets, B.J. Healy, Robert T. Brandt Jr., T.P. Eck Jan 1995

Combinations Of Nonprotein Nitrogen And Natural Protein Affect Performance Of Finishing Steers Fed Flaked Corn Diets, B.J. Healy, Robert T. Brandt Jr., T.P. Eck

Kansas Agricultural Experiment Station Research Reports

Two hundred crossbred steers (7 85 lb) were used to evaluate the effects of the relative proportion of supplemental nitrogen derived from soybean meal (SBM) and urea. Treatments included an unsupplemented negative control and four 13% CP diets containing SBM:urea proportions (nitrogen basis) of 100:0, 67:33, 33: 67, and 0:100. Steers fed the control diets gained 38% slower (P<.01); ate 4% less feed (P<.10); were 33% less efficient (P<.01); and had lighter carcasses (P<.01) with less backfat (P<.01), less kidney, pelvic, and heart fat (KPH; P<.12), less ribeye area (REA; P<.11) , and less marbling (P<.01) than nitrogen-supplemented steers. Among steers fed supplemented diets, feed intake increased linearly as proportion of SBM increased (P<.01) . Daily gain (P<.05) and feed:gain (P<.05) responded quadratically and was best for steers fed combinations of the nitrogen sources. Similarly, hot carcass weights and backfat thickness were greater (P<.06) for steers fed the mixed supplements. There was a tendency for a linear increase in KPH as proportion of urea in the diet was increased (P<.14). Yield grade, ribeye area, and marbling were unaffected by SBM:urea proportions. In high-concentrate finishing diets, at least some of the supplemental nitrogen should be derived from a natural, degradable-protein source.

Kansas Environmental Regulations, Joseph P. Harner, L. Hess, James P. Murphy

Kansas Agricultural Experiment Station Research Reports

The Kansas Department of Health and Environment (KDHE) enforces two different regulation s in the state of Kansas. One set of regulation s is from the Federal Environmental Protection Agency (EPA) and applies to larger operations. The other is a set of Kansas regulation s created by our state legislature for smaller operations. EPA regulations pertain to confined feeding operation s in excess of 1,000 animal units and require an EPA National Pollution Discharge Elimination System (NPDES) permit. Because an animal unit for the NPDES permit is defined as one beef animal, a feedlot with a capacity of 1 ...

Top Spoilage Losses For Corn And Forage Sorghum Silages Stored In Bunker Silos, D.L. Holthaus, B.S. Dalke, L. Pfaff, John E. Boyer, K.K. Bolsen, Matthew A. Young

Kansas Agricultural Experiment Station Research Reports

Corn and forage sorghum silages were stored in small bunker silos for 180 days. Dry matter (DM) and organic matter (OM) losses, fermentation characteristics , in-situ DM digestibility, and temperatures were measured at 10, 20, and 30 inches from the original silage surface. Sealing the exposed surface increased DM and OM recoveries and improved fermentation quality and nutritive value in both crops, regardless of depth. The unsealed corn silages were much hotter within the top 3 ft than sealed silages, indicating aerobic losses. As expected , the unsealed silages from both crops deteriorated severely i n the top 20 inches. Placing a ...

Kansas Agricultural Experiment Station Research Reports

A 6-year study was designed to measure the influences of stocking rate and grazing system on performance of cow-calf pairs grazing tallgrass prairie. This paper summarizes the initial 3 years. Late-season rest-rotation was compared to continuous grazing over low, moderate, and high stocking rates. No differences (P>.10) were observed in body weight of cows or calves as a result of grazing system or stocking rate. However, calf weaning weight tended (P=.20) to be greater with continuous grazing than with late season rest-rotation. Cow body condition score was unaffected (P>.10) by stocking rate or grazing system. Conception rates ...

Radiometric Measurement Of Forage Quantity, R.C. Cochran, G. Towne, K. C. Olson

Kansas Agricultural Experiment Station Research Reports

A 16-band multispectral radiometer (MSR) was used to measure the amount of forage biomass present on several dates in native tallgrass prairie pastures during the 1992 to 1994 growing seasons. Reflectance data collected with the MSR were used a s inputs for a neural network computer program. The neural network used the reflectance data to predict forage biomass. Biomass estimates made with the MSR were found to predict actual biomass, as measured by hand-clipping, across all plant growth stages with an error of approximately 6%. Radiometric determination of biomass is a reliable alternative to hand-clipping and can be accomplished in ...

Kansas Agricultural Experiment Station Research Reports

The meat industry and Food Safety and Inspection Service (FSIS) strive to minimize carcass contamination during slaughter and subsequent processing. Because microbial contamination during slaughter cannot be avoided completely, decontamination methods must be addressed. This overview emphasizes process intervention studies conducted at Kansas State University to determine the most effective intervention points and technologies to control microbiological hazards in meat and meat products. Our research shows that trimming of gross contamination followed by washing is a reasonable approach to minimizing microbial contamination on beef carcasses. We also found that sanitation of subprimal cuts may be just as effective as treating ...

Factors Affecting Premature Browning In Cooked Ground Beef, Melvin C. Hunt, K.E. Warren, Donald H. Kropf, M.A. Hague, C.L. Waldner, Sally L. Stroda, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Some ground beef patties developed an internal, brown cooked color and looked well-done at temperatures as low as 13 1EF, whereas normal patties were re d to pink. The premature brown color was not relate d to percent fat; patty compaction; animal source and maturity; pH (5.5 to 5.8); or concentrations of raw patty heme and nonhemeiron, myoglobin, and total pigment. Because oxidation-reduction potential and total reducing activities were higher (P<.05) and TBA numbers were lower (P<.05) in normal than prematurely brown patties, the brown color is apparently related to greater patty oxidation.
