Determining The Accuracy Of Gestation Feed Drops (2008), J D. Schneider, Michael D. Tokach, Steven S. Dritz, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband Jan 2008

Determining The Accuracy Of Gestation Feed Drops (2008), J D. Schneider, Michael D. Tokach, Steven S. Dritz, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Objective: To determine the accuracy of three different types of gestation feed drops. Materials and methods: Econo, Accu, and Ultra feed drops (Automated Production Systems, Assumption, Illinois) were attached to feed lines at three angles (90Ëš, 75Ëš, and 60Ëš). Feed was collected and weighed at settings of 2, 4, 6, 8, and 10 lb (0.9, 1.8, 2.7, 3.6, and 4.65 kg) for the Econo and Accu feed drops and 2, 4, 6, and 8 lb for the Ultra feed drops. Results: There was a drop type × angle × feed level interaction (P<.01) for the feed settings versus the actual amount dropped. At 90Ëš, the relationship between the feeder setting (x) and actual quantity of feed dropped was best described by the regression equation (1.156x + 0.244) for the Econo, (1.010x + 0.072) for the Accu, and (1.009x + 0.231) for the Ultra feed drops. At 75Ëš, the regression equations were (1.014x — 0.139) for the Econo, (0.997x + 0.057) for the Accu, and (1.005x + 0.156) for the Ultra feed drops. At 60Ëš, the regression equations were (0.689x — 0.076) for the Econo, (0.989x — 0.249) for the Accu, and (0.951x + 0.026) for the Ultra feed drops. Implications: The type of feed drop and its angle relative to the feed line influences the amount of feed dispensed at a feeder setting. The Accu and Ultra feed drops more accurately dispense the correct amount of feed than the Econo feed drops.; Journal of Swine Health and Production; 16; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008

Kansas Agricultural Experiment Station Research Reports

Developing management strategies for Korral Kools will help producers provide cooling in the housing area while minimizing the operational cost of the Korral Kools system. Two experiments were conducted at a dairy in Saudi Arabia to evaluate operational time of Korral Kools for multiparous and primiparous dairy cows. For multiparous cows, running time per day of Korral Kools should be continuous, but for primiparous cows, no difference in performance was detected between 21 and 24 hours. However, producers need to be careful when reducing daily operation time of Korral Kools for primiparous cows because elevated core body temperatures were observed …

Packaging Atmospheres Alter Beef Tenderness, Fresh Color Stability, And Internal Cooked Color (2008), J.P. Grobbel, Michael E. Dikeman, George A. Milliken, Melvin C. Hunt Jan 2008

Packaging Atmospheres Alter Beef Tenderness, Fresh Color Stability, And Internal Cooked Color (2008), J.P. Grobbel, Michael E. Dikeman, George A. Milliken, Melvin C. Hunt

Kansas Agricultural Experiment Station Research Reports

Several meat quality traits affect consumers' overall purchase decisions and satisfaction with meat products, but color is the major factor affecting purchasing decisions. According to some researchers, tenderness is the most important palatability attribute in consumers' overall eating experience. Case-ready packaging in the meat industry is growing at a rapid rate and generally includes modified atmosphere packaging (MAP) with specific gases. Advantages of MAP include use of a centralized location, improved sanitation control, more consistent products, and increased marketing flexibility. Packaging beef in highoxygen (HiO2) MAP results in a desirable bright red lean color but can have detrimental effects on …

Packaging Atmospheres And Injection Enhancement Affect Beef Tenderness And Sensory Traits, J.P. Grobbel, Michael E. Dikeman, George A. Milliken, Melvin C. Hunt

Kansas Agricultural Experiment Station Research Reports

Case-ready meat provides many benefits, including quality and safety. Meat packaged in high-oxygen (HiO2) modified atmosphere packaging (MAP) has a desirable bright red display color but may have increased off- flavors and decreased tenderness. According to several international research reports, steaks aged and packaged in HiO2 MAP had more off-flavor, including warmed-over flavor, and were less tender and juicy than steaks aged in vacuum packaging (VP). Research at Kansas State University found that injection-enhanced beef quadriceps muscles packaged in HiO2 MAP were less tender and had more offflavors than those in ultra-low oxygen MAP. Detrimental effects of O2 on tenderness …

Vitamin A Restriction During Finishing Benefits Beef Retail Color Display Life (2008), M.J. Daniel, A.M. Arnett, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Because the beef industry commonly uses marbling as an indicator of meat palatability, determining the most cost effective methods of increasing quality grade in cattle is a high priority. Previous research showed that weaning calves at around 90 instead of 200 days of age can be beneficial in reducing cow production costs and increasing marbling in feedlot steers. Other studies demonstrated that high levels of vitamin A inhibit development of intramuscular fat. Vitamin A restriction is used commonly in Japanese cattle to increase marbling scores; this stimulated interest in applying this restriction in U.S. beef production systems. However, little research …

Dried Distiller’S Grains In Steam-Flaked Corn Finishing Diets With Decreased Roughage Levels (2008), M.L. May, M.J. Quinn, K.K. Karges, M.L. Gibson, Brandon E. Depenbusch, James S. Drouillard Jan 2008

Dried Distiller’S Grains In Steam-Flaked Corn Finishing Diets With Decreased Roughage Levels (2008), M.L. May, M.J. Quinn, K.K. Karges, M.L. Gibson, Brandon E. Depenbusch, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Distiller's grains are the primary coproduct derived from fuel ethanol production. As the fuel ethanol industry expands into the High Plains, distiller's grains are becoming increasingly available as an alternative feed for livestock. Optimizing the use of distiller's grains in flaked grain rations is important to maintaining a competitive advantage among feedlot producers in this region. Because distiller's grains are relatively high in fiber, it is conceivable that the level of roughages in feedlot diets could be reduced when distiller's grains are fed to cattle. Roughages normally have low energy density; therefore, the cost per unit of energy from roughages …
