In Exp. 2, pigs (initially 130 lb) were allotted to one of four dietary energy levels (1,250 ME/lb, 1,360 ME/lb, 1,475 ME/lb, 1,590 ME/lb). Increasing dietary ME levels ...


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

Optimal Parity Distribution – When Is The Best Time To Cull Sows?, 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 ...

Kansas Agricultural Experiment Station Research Reports

Decreasing the dietary electrolyte balance (dEB) in diets for lactating sows from 500 to 100 mEq/kg increased piglet survivability but had no effect on litter weight gain. Decreased dEB reduced pH and bacteria in the sows urine and, thus, could influence the health status of the reproductive tract.; Swine Day, Manhattan, KS, November 16, 2000


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

Market Versus Formula-Derived Prices For Segregated Early-Weaned Pigs, 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 ...


Effects Of Increasing L-Lysine Hcl In Corn-Soybean Meal Diets On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts, M De La Llata, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2000

Effects Of Increasing L-Lysine Hcl In Corn-Soybean Meal Diets On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts, M De La Llata, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

An experiment using 1,200 gilts (65 to 260 lb) was conducted to determine the effects of increasing L-lysine HCl in cornsoybean meal diets on growth performance and carcass characteristics. The dietary treatments consisted of a control diet with no added L-lysine HCl and six increasing levels of L-lysine HCl (1, 2, 3, 4, 5, and 6 lb/ton) replacing the lysine provided by soybean meal. A negative control treatment was used to ensure that dietary lysine was not above required levels. Increasing L-lysine HCl above 3 lb/ton decreased ADG and increased F/G. Backfat was increased and FFLI ...


Effects Of Freezing Pork Chops On Warner-Bratzler Shear Force And Cookery Traits, B S. Andrews, John A. Unruh, Melvin C. Hunt, Curtis L. Kastner Jan 2000

Effects Of Freezing Pork Chops On Warner-Bratzler Shear Force And Cookery Traits, B S. Andrews, John A. Unruh, Melvin C. Hunt, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Eighty-one boneless pork loins were used to determine the influence of freezing and pH on Warner-Bratzler shear force (WBS) values and cookery traits. Chops with lower pH (<5.5 to 5.5) had higher cooking losses than chops with intermediate pH (5.7 to 5.9) and higher pH (6.0 to >6.2). Similar to cooking losses, total moisture losses decreased with increased pH. Frozen chops had lower WBS values (more tender) than fresh chops. However, fresh chops had a higher total yield (lower moisture loss) than frozen chops.; Swine Day, Manhattan, KS, November 16, 2000
