Effects Of Cattle Grazing Cropresidues On Soil Bulk Density (2000), R.K. Taylor, John W. Slocombe Jan 2000

Effects Of Cattle Grazing Cropresidues On Soil Bulk Density (2000), R.K. Taylor, John W. Slocombe

Kansas Agricultural Experiment Station Research Reports

Effects of cattle grazing on soil bulk density were measured at two sites in central Kansas. Samples were taken at depths of 0 to 3 in. and 3 to 6 in. from grazed and ungrazed areas at five locations in each field. No statistical difference (P>0.01) between bulk densities of the two areas occurred at the 3 to 6 in. depth for either site. However, soil in the grazed areas had significantly higher (P<0.01) bulk density than that in the ungrazed areas at the 0 to 3 in. depth at both sites.

Optimal Parity Distribution – When Is The Best Time To Cull Sows? (2000), Kevin C. Dhuyvetter Jan 2000

Optimal Parity Distribution – When Is The Best Time To Cull Sows? (2000), Kevin C. Dhuyvetter

Kansas Agricultural Experiment Station Research Reports

The economic impact of alternative sowculling strategies was examined by simulating costs and returns for a farrowing-to-weaning swine operation. Culling strategies considered were to sell sows after parity 1 (P1) through parity 10 (P10). These 10 culling strategies resulted in different parity distributions. The optimal parity distribution is a complex issue, because it is related to conception rates, litter size, feed intake, as well as other factors. Results of this analysis indicate that the most economical time to cull a sow is after her eighth or ninth parity. This results in a breeding herd comprised of 18 to 20% gilts …

Market Versus Formula-Derived Prices For Segregated Early-Weaned Pigs (2000), Kevin C. Dhuyvetter Jan 2000

Market Versus Formula-Derived Prices For Segregated Early-Weaned Pigs (2000), Kevin C. Dhuyvetter

Kansas Agricultural Experiment Station Research Reports

A formula for deriving the price of segregated early-weaned (SEW) pigs using prices of grain, soybean meal, and market hog was estimated based on return on investment being equal for all three phases of production—farrowing, nursery, and finishing. The USDA- reported SEW pig prices were compared with formula-derived prices. The level of correlation between these two series was sensitive to how prices of grain, soybean meal, and market hog were chosen. Using expected prices in the formula resulted in SEW prices that were correlated strongly with reported market prices. Using hindsight cash prices in the formula resulted in SEW formula …

In Vitro Degradation Of Betaine By Ruminal Microbes (2000), C.A. Löest, C.K. Armendariz, Evan C. Titgemeyer Jan 2000

In Vitro Degradation Of Betaine By Ruminal Microbes (2000), C.A. Löest, C.K. Armendariz, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

An in vitro study was conducted to evaluate the degradation of betaine sources by rumen microbes. Five sources of betaine (anhydrous betaine, betaine-HCl, feed-grade betaine, lipidcoated betaine, and concentrated separator byproduct) were incubated in rumen fluid collected from steers fed grain- or forage-based diets. In vitro degradation of betaine was slower with the high roughage diet than the grain diet. Betaine from concentrated separator by-product was degraded most rapidly, but no large differences occurred among the other four sources. The disappearance of betaine from lipid-coated product indicates that it did not resist ruminal degradation. Although betaine from all sources was …

Impacts Of Corn And Fed-Cattle Prices On Price Slides For Feeder Cattle (2000), Kevin C. Dhuyvetter, Ted C. Schroeder Jan 2000

Impacts Of Corn And Fed-Cattle Prices On Price Slides For Feeder Cattle (2000), Kevin C. Dhuyvetter, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Several important determinants need to be considered when analyzing price slides (priceweight relationships) for feeder cattle. The two most economically important determinants of price-weight slides are expected fed-cattle price and corn price. Price-weight slides increase notably when corn prices decline (i.e., the premium for light-weight calves increases as feed prices decrease). Likewise, when expected fed-cattle prices increase, price-weight slides increase. Knowing this information can help producers who forward contract feeder cattle, backgrounders making decisions regarding feeding calves to various weights, and producers making feeder cattle purchase decisions.

Raw Milk Quality: The Processor's Point Of View, Karen A. Schmidt Jan 2000

Raw Milk Quality: The Processor's Point Of View, Karen A. Schmidt

Kansas Agricultural Experiment Station Research Reports

Raw milk quality is important to the processor for many reasons, this quality can be assessed by several different tests. Quality tests are used to ensure that the raw milk meets legal USDA standards as well as some of the individual requirements of the processor. Although some quality tests can be done in a matter of minutes, others require up to several days to complete. Because milk quality deteriorates relatively quickly, it is important to concentrate on those tests that provide the greatest amount of information in the shortest time. This information then is extrapolated to assess the "actual raw …
